Open Issues in 4.3.3
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4037015 | The NVUE commands to delete SNMP users, and change authentication passwords and encryption passphrases are not successful. | 4.3.0-5.9.1 | 5.9.2-5.10.1, 5.10.0-5.10.1 |
| 3773177 | When you try to upgrade a switch from Cumulus Linux 5.5 or earlier to 5.8.0 or later with package upgrade, you see errors for expired GPG keys that prevent you from upgrading. To work around this issue, install the new keys with the following commands, then upgrade the switch.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/c/cumulus-archive-keyring/cumulus-archive-keyring_4-cl5.6.0u5_all.deb | 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3684998 | DHCP lease information is not collected in the cl-support file. | 4.3.0-5.6.0 | 5.7.0-5.10.1 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 | 5.6.0-5.10.1 |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 | 5.6.0-5.10.1 |
| 3429530 | On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.10.1 |
| 3330705 | When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. | 3.7.0-5.3.1 | 5.4.0-5.10.1 |
| 3327477 | If you use su to change to a user specified through TACACS+, the user becomes the local tacacs0 thru tacacs15 user instead of the named user to run sudo commands. As a result, the named user password might not match the local tacacs0 thru tacacs15 user password. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3321391 | On the NVIDIA SN2410 switch, ports with optical transceivers show FAULT errors in the sensor command output. | 4.2.1-5.3.1 | 5.4.0-5.10.1 |
| 3291548 | In EVPN deployments, a buffer lockup for split or pre-split ports can occur on Spectrum-2 and Spectrum-3 switches. As result, traffic coming in on these ports is dropped in the RX buffer. To work around this issue, restart switchd. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 3218207 | Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 | 5.3.0-5.10.1 |
| 3216921 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-3.7.16, 4.3.0-4.4.5 | |
| 3216759 | With the ip-acl-heavy TCAM profile, the following message might appear after you install an ACL with NCLU or cl-acltool and the ACL might not work correctlyhal_flx_acl_util.c:378 ERR hal_flx_acl_resource_release resource region 0 size 7387 create failed: No More ResourcesTo work around this issue, change the TCAM profile to acl-heavy or ip-acl-heavy with ACL non-atomic mode. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3168564 | In a large scale VXLAN configuration (for example if you have more than 8500 VLANs across ports), switchd might crash when you restart clagd or when all bonds go operationally down, then upOn Trident3 switches running Cumulus Linux 4.3.1, NVIDIA validates the VLAN scale limit for VXLAN deployments with 8500 VLANs across ports with LACP bypass disabled. | 4.3.1-4.4.5 | |
| 3163845 | If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. | 4.3.1-4.4.5 | |
| 3138746 | The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3131423 | During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3129819 | On the EdgeCore AS4610 switch, the clagd service loses communication after 198 days of uptime. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3119615 | In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.10.1 |
| 3117340 | When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service. To recover, restart the networking service with the sudo systemctl restart networking command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3093966 | On Broadcom switches, INPUT chain iptable rules filter IPv6 packets matching the rules. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3093863 | The snmpd process will slowly leak memory when you poll TCP-MIB objects. To work around this issue, restart the snmpd service to free memory with the systemctl restart snmpd command. | 3.7.16-4.4.3 | 4.4.4-4.4.5, 5.2.0-5.10.1 |
| 3089165 | A slow memory leak might occur in switchd} if the route fails to install in hardware when hardware resources are exhausted. | 4.2.1-4.4.3 | 4.4.4-4.4.5 |
| 3084027 | Under a high load, you might see ingress drop counters increase. The drops are classified as HwIfInDiscards in ethtool and shown as ingress_general in hardware. | 4.3.0-4.4.5, 5.0.0-5.10.1 | |
| 3073668 | On the EdgeCore AS4610 switch, when you change the speed of any of the SFP+ ports, the other SFP+ ports flap. | 3.7.12-3.7.16, 4.3.0-4.4.5 | |
| 3072613 | When you delete a bond interface with NCLU, BGP peer group configuration is removed. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3059135 | In an OSPF configuration, after you change the IPv6 subnet mask, the old address remains in the RIB as a connected OSPF route To resolve this issue, restart FRR with the sudo systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3046023 | The cl-resource-query command output shows ECMP nextHop Table exhaustion (above 100 percent utilization) and the switchd.log file contains ECMP resource errors with routes and next hops failing to install. | 4.2.1-5.1.0 | 5.2.0-5.10.1 |
| 3007564 | After you delete the last vxlan-remoteip configuration line from the /etc/network/interfaces file and run the ifreload -a command, the corresponding BUM flood entry is not removed. | 3.7.15-5.0.1 | 5.1.0-5.10.1, 5.2.0-5.10.1 |
| 2999341 | CVE-2021-3570The ptp4l program in linuxptp, an implementation of the Precision Time Protocol (PTP), does not validate the messageLength field of incoming messages, allowing a remote attacker to cause a denial of service, information leak, or potentially remote code execution Fixed: 1.9.2-1+deb10u1 | 4.2.1-4.4.1 | 4.4.2-4.4.5 |
| 2968495 | If switchd requires more time to update port or bond configuration after the port or bond flaps, the systemd watchdog times out. As result, systemd might assume that switchd is unresponsive and restarts it. | 4.2.1-4.4.2 | 4.4.3-4.4.5, 5.1.0-5.10.1 |
| 2961008 | SNMP reports the same ifType of ethernetCsmacd(6) for loopback interfaces. | 3.7.15-4.4.2, 5.0.0-5.0.1 | 4.4.3-4.4.5, 5.1.0-5.10.1 |
| 2951110 | The net show time ntp servers command does not show any output with the management VRF. | 3.7.15-3.7.16, 4.1.1-4.4.5, 5.0.0-5.10.1 | |
| 2940051 | In an MLAG configuration with traditional bridges, MAC addresses are seen over peer link during ifreload when adding new VLANS or bridges. | 3.7.14.2-3.7.15, 4.3.0-4.4.5 | 3.7.16, 5.0.0-5.10.1 |
| 2902013 | The NCLU commit command adds a five second delay. | 4.2.1-4.4.5 | |
| 2896450 | On the Dell N3248PXE switch, fixed RJ45 interfaces with PoE neighbors can end up in Paused mode after a switchd restart, which blocks traffic on that interface. To work around this issue, restart switchd a second or third time until all interfaces are functioning correctly, or reboot the switch. | 4.3.0-4.4.5 | |
| 2893895 | CVE-2020-35498: A vulnerability was found in openvswitch.

| 2845531 | If you update the MAC address of an SVI when the SVI is in a protodown state (for example, when no bridge ports that carry this VNI are operationally up or if the MAC address of the SVI’s parent bridge changes), clagd does not notice the change. The MLAG peer incorrectly maintains a PERMANENT neighbor entry for the SVI IP that points to the old MAC address. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 2838905 | On Broadcom ARM switches, the NTP clock slowly drifts to a very high offset (over 500ms) and the clock is not able to synchronize. To work around this issue, use the chrony implementation of NTP instead of ntpd. chrony synchronizes the system clock faster and with better accuracyInstructions for using chrony are here : https://docs.nvidia.com/networking-ethernet-software/knowledge-base/Network-Solutions/Chrony-on-Cumulus-Linux/ | 4.3.0-4.4.5 | |

| 2556369 | If you use NCLU to configure an ACL for eth0, you can’t designate it as an INPUT rule; the rule is automatically created as a FORWARD rule in the /etc/cumulus/acl/policy.d/50_nclu_acl.rules file.To work around this issue, manually create an ACL in the /etc/cumulus/acl/policy.d/ file with “-A INPUT -i eth0”. | 4.2.1-4.4.5 | |
| 2556082 | The NCLU net del vrf command does not delete a numbered VRF. For example:
| 4.2.1-4.4.5 | |
| 2556081 | You cannot set the time zone can with NCLU commands. | 4.1.1-4.4.5 | |
| 2555873 | On Mellanox switches, egress ACLs with VLAN keys do not filter layer 2 multicast or broadcast traffic. | 4.3.0-4.4.5 | |
| 2555763 | The NCLU net del bgp neighbor command does not delete the neighbor and displays an error similar to the following:
To work around this issue, use the FRR command to delete a neighbor. | 4.3.0-4.4.5 | |
| 2555613 | The net show configuration commands command incorrectly displays the NCLU syntax to disable IPv6 forwarding on interfaces. For example:
The correct NCLU command to disable IPv6 forwarding is net add vlan 1 ipv6 forward off (without the hyphen). | 4.2.1-4.4.5 | |
| 2555318 | If you try to enable BGP graceful restart when it is already enabled, you see an error similar to the following in the frr.log file:
This error has no functional impact. | 4.3.0-4.4.5 | |
| 2554986 | The ethtool utility doesn’t contain the latest values, as a result the Revision Compliance field shows Unallocated. | 4.2.1-4.4.5 | |
| 2554812 | If the RMAC of a layer 3 SVI changes, the show vrf vni command is not updated with the new value. However, the new RMAC is seen in the show evpn vni command and is present on self-originated EVPN routes. | 4.2.1-4.4.5 | |
| 2554783 | If you apply an outbound route map to a BGP peer that uses set as-path prepend last-as, advertised locally-originated routes have the ASN of the peer prepended to the AS path.This might trigger AS path loop prevention on the peer, where the peer ignores locally-originated prefixes. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 2554709 | The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. | 3.7.13-3.7.16, 4.2.1-4.4.5 | |
| 2554670 | When you have a large number of ACLs, the cl-acltool -L ip and cl-resource-query commands take a long time to complete. | 4.3.0-4.4.5 | |
| 2554582 | On switches with the Maverick ASIC, control traffic is dropped due to receive buffering. | 4.2.0-4.4.5 | |
| 2554533 | On the ARM platform, NTP peer associations slowly increase to larger offsets (~500ms). | 4.0.0-4.4.5 | |
| 2554466 | Kernel routes added by iproute2 are missing in FRR after an interface flap.To work around this issue, configure a static route in FRR. | 4.2.1-4.4.5 | |
| 2554299 | In a VRRP configuration, BGP unnumbered sessions for VRFs fail to establish after a networking restart. | 4.2.0-4.3.3 | 4.4.0-4.4.5 |
| 2554222 | The NCLU command to enable bridge learning fails. As a work around, enable bridge learning in the /etc/network/interface file. For example:
| 4.2.1-4.4.5 | |
| 2554218 | MLAG packets received on the peer link are dropped instead of routed. | 4.2.0-4.4.5 | |
| 2554202 | The output of the net show commit command does not show the last commit or the specified commit number but is empty instead. | 4.2.1-4.4.5 | |
| 2553989 | Default policer configured for LACP as an INPUT chain rule in 00control_plane.rules is meant to protect CPU from an LACP storm. When LACP storm is originating out of a single bond or bond member interface in a switch with multiple bond interfaces, there is a possibility of other LACP bond interface(s) going down. | 4.2.1-4.4.5 | |
| 2553887 | When using TACACS+ configured with a DEFAULT user providing privilege level lower than 16, TACACS+ configured users with privilege level 16 access might not be able to run privilege level 16 NCLU commands, such as net add and net del and see an error similar to the following:
To work around this issue, remove the DEFAULT user from the TACACS+ server. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2553677 | When you configure an SNMPv3 user with the net-snmp-config configuration command from the libsnmp-dev package, you get an error message similar to the one below:
To work around this issue, use the NCLU command to configure SNMPv3 user parameters; for example:
Alternatively, directly edit the /etc/snmp/snmpd.conf file as described in the documentation. | 3.7.13-3.7.16, 4.0.0-4.4.5 | |
| 2553237 | The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. | 4.2.0-4.4.5 | |
| 2553116 | When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition. Avoid setting the interface speed or duplex mode directly with ethtool. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2553015 | If a neighbour contains a special character in PortID for LLDP, the net show interface command does not display the LLDP information or the command might fail. | 3.7.10-3.7.16, 4.2.0-4.4.5 | |
| 2552691 | On the EdgeCore AS4610 switch, the eth0 interface remains down when physically connected to a 1G interface. To work around this issue, configure the link speed to 1000 and set auto-negotiation on for the eth0 interface, then flap eth0 with the ip link set eth0 down/up command to bring up the port. | 4.2.0-4.4.5 | |
| 2552453 | On the Mellanox switch, RoCE with PFC configuration is not applied to all ports in hardware when a range is used in the traffic.conf file.To work around this issue, use NCLU to configure RoCE with PFC or list individual ports in the traffic.conf file. | 4.2.0-4.4.5 | |
| 2552309 | The following messages are seen on an Edgecord Minipack-AS8000 running Cumulus Linux 4.2.0:
These messages are for internal validation purposes only and can be safely ignored. | 4.2.0-4.4.5 | |
| 2552294 | NCLU restarts FRR when removing a BGP VRF IPv4 aggregate-address command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2552266 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.7.14-3.7.16, 4.0.0-4.4.5 | |
| 2551666 | If you modify an interface name, then reuse the previous interface name for a different VLAN, the ifreload -a command generates an error similar to the following:
| 4.1.0-4.4.5 | |
| 2551578 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2551565 | If you toggle VRRP priority values between VRRP routers, then restart switchd, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affectedTo work around this issue, remove, then add back the VRRP configuration with NCLU or vtysh commands. | 3.7.13-3.7.16, 4.2.0-4.4.5 | |
| 2551335 | When TACACS+ is configured and the management VRF is enabled, users with privilege level 13 are prevented from running ip and cat commands. | 4.0.0-4.4.5 | |
| 2551305 | The net show configuration command provides the wrong net add command for ACL under the VLAN interface. | 3.7.12-3.7.16, 4.1.0-4.4.5 | |
| 2551273 | On a Mellanox SN2010 switch, the Locator LED is on after you upgrade Cumulus Linux. | 4.1.0-4.4.5 | |
| 2551221 | When span-to-cpu is enabled on L3 swp interface with an IP address configured, packets with destination IP as switchport’s IP address don’t reach switchport. To capture packets directed towards switcport’s IP, disable span-to-cpu and use tcpdump on swichport instead. | 4.2.0-4.4.5 | |
| 2551111 | If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. | 4.0.0-4.4.5 | |
| 2550974 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.16, 4.1.1-4.4.5 | |

| 2550444 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550443 | The net show rollback description command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550243 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:
| 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550056 | The ACCTON-DIAG option under the Cumulus Linux GRUB menu does not work. When you select this option, you see the following error:

These errors are result of user space acting on kernel events a bit slow. The mlxsw_minimal driver is added during kernel boot; An SDK reset causes the driver to be deleted and re-instantiated; User space handler for thermal zone add sees the add first; But the underlying device is deleted before it can act on it. This situation is rectified as the mlxsw_minimal driver is re-instantiated later; | 4.1.0-4.4.5 | |

| 2546991 | The FRR service does not provide a way for automation to know if the configuration applied properly. To work around this issue, execute the vtysh -f command in the automation file before starting the FRR service to validate the functional configuration and return an error code. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546895 | If you have configured a higher number of ports and VLANs (ports x VLANs) or the switch is a lower-powered (CPU) platform, the switchd service might fail to send a systemd keepalive within the watchdog timeout value (2 minutes by default) and you see an error similar to the following:bq. systemd[1]: switchd.service watchdog timeout (limit 2min)!To workaround this issue, either reduce the number of configured interfaces and, or VLANs, or increase the systemd timeout for switchd.serviceTo increase the systemd timeout:1.Edit the /etc/systemd/system/switchd.service.d/override.conf file and increase the WatchdogSec parameter2.Restart the switchd service with the sudo systemctl restart switchd.service commandsystemd attempts to restart the switchd service automatically (after the watchdog timeout).

| 2546874 | On the Dell S5232F, S5248F, S5296F, and S3048 switch, using the poweroff or halt commands does not fully power off the switch. | 4.0.0-4.4.5 | |
| 2546255 | On the EdgeCore Minipack-AS8000 switch, a 100G DAC link does not come up when auto-negotiation is enabled on the neighbor. This switch does not support 100G DAC auto-negotiation at this time. | 4.0.0-4.4.5 | |
| 2546225 | When you execute the following command on the Delta AG6248C switch, the switch reboots and then comes right back into Cumulus Linux without installing the new image. The install image is still in /var/lib/cumulus/installer, which causes issues with cl-support.
To work around this issue, use the onie-select command to access ONIE, and then use the nos-install command in ONIE to install a new binary image. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546131 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2545837 | If you use the NCLU commands to configure NTP and run the net add time ntp source command before you run the net add time ntp server command, the /etc/ntp.conf file is misconfigured.To work around this issue, run the net add time ntp server command before you run the net add time ntp source command. | 3.7.10-3.7.11, 4.0.0-4.4.5 | 3.7.12-3.7.16 |
| 2545520 | The length of the netlink message is not set properly for non-bridge family type messages. The same length is used for both bridge and non-bridge even though the bridge family type message has an extra attribute. This causes extra bytes to be left over in non-bridge family type netlink messages. | 3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |

| 2544723 | Setting ProtoDown on ports populated with SFP modules providing RJ-45 1000BASE-T interfaces does not cause the carrier to be dropped. The kernel shows carrier down; however, the remote device still shows a link. | 3.7.6-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2544463 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2544456 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2544311 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2544155 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2544113 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2543937 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543915 | When you enable a service in the management VRF, systemctl issues a warning similar to the following:Warning: The unit file, source configuration file or drop-ins of ntp@mgmt.service changed on disk. Run ‘systemctl daemon-reload’ to reload unitYou can safely ignore this warning. | 4.0.0-5.9.2 | 5.10.0-5.10.1 |

| 2543816 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11, 4.0.0-4.4.5 | 3.7.12-3.7.16 |
| 2543781 | NCLU does not allow you to configure OSPF NSSAs. For example:
To work around this issue, use FRR instead. For example:
| 3.7.7-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543724 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:

| 2543401 | On the Mellanox Spectrum-2 switch, the time required to establish a link (from the time a link is set to admin up until the link becomes operationally up) can take up to 15 seconds on 40G interfaces and up to 30 seconds on 100G interfaces.To work around this issue, wait up to 15 seconds on 40G interfaces and 30 seconds on 100G interfaces for the link to establish. | 4.0.0-4.4.5 | |
| 2543211 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2543164 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2543096 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542945 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:
| 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542837 | On Mellanox switches, policer iptables are not working as expected. For example, when using a policer with mode KB/MB/GB to rate-limit interfaces, the syntax is accepted but the data plane transfer speed is not affected by the rule. | 3.7.6-3.7.8, 4.0.0-4.4.5 | 3.7.9-3.7.16 |
| 2542305 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542301 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2541212 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2541029 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540753 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:
| 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540444 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540274 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540204 | When links come up after FRR is started, VRF connected routes do not get redistributed. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540192 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540155 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2540042 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto lines exist. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2539994 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539962 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2539670 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539124 | The net add interface command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538590 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2537699 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2537544 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2536576 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 4.0.0-4.4.5 | |
| 2536384 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 4.0.0-4.4.5 | |
| 2536242 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 4.0.0-4.4.5 | |
| 2535209 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.7.5-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2534734 | Span rules matching the out-interface as a bond do not mirror packets. | 4.0.0-4.4.5 | |
| 2533691 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 4.0.0-4.4.5 | |
| 2533337 | When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. | 4.0.0-4.4.5 | |
| 2531273 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. | 4.0.0-4.4.5 |

| 3773177 | When you try to upgrade a switch from Cumulus Linux 5.5 or earlier to 5.8.0 or later with package upgrade, you see errors for expired GPG keys that prevent you from upgrading. To work around this issue, install the new keys with the following commands, then upgrade the switch.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/c/cumulus-archive-keyring/cumulus-archive-keyring_4-cl5.6.0u5_all.deb | 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3759932 | When you migrate virtual machines from one rack to another rack, there might be occasional problems reaching the server after Vmotion. | 4.3.1-4.3.2 | 4.3.3-4.4.5 |
| 3684998 | DHCP lease information is not collected in the cl-support file. | 4.3.0-5.6.0 | 5.7.0-5.10.1 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 | 5.6.0-5.10.1 |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 | 5.6.0-5.10.1 |
| 3429530 | On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.10.1 |
| 3330705 | When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. | 3.7.0-5.3.1 | 5.4.0-5.10.1 |
| 3327477 | If you use su to change to a user specified through TACACS+, the user becomes the local tacacs0 thru tacacs15 user instead of the named user to run sudo commands. As a result, the named user password might not match the local tacacs0 thru tacacs15 user password. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3321391 | On the NVIDIA SN2410 switch, ports with optical transceivers show FAULT errors in the sensor command output. | 4.2.1-5.3.1 | 5.4.0-5.10.1 |
| 3291548 | In EVPN deployments, a buffer lockup for split or pre-split ports can occur on Spectrum-2 and Spectrum-3 switches. As result, traffic coming in on these ports is dropped in the RX buffer. To work around this issue, restart switchd. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 3218207 | Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 | 5.3.0-5.10.1 |
| 3216922 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users). | 3.7.0-5.2.1 | 5.3.0-5.10.1 |
| 3216921 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-3.7.16, 4.3.0-4.4.5 | |
| 3216759 | With the ip-acl-heavy TCAM profile, the following message might appear after you install an ACL with NCLU or cl-acltool and the ACL might not work correctlyhal_flx_acl_util.c:378 ERR hal_flx_acl_resource_release resource region 0 size 7387 create failed: No More ResourcesTo work around this issue, change the TCAM profile to acl-heavy or ip-acl-heavy with ACL non-atomic mode. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3168564 | In a large scale VXLAN configuration (for example if you have more than 8500 VLANs across ports), switchd might crash when you restart clagd or when all bonds go operationally down, then upOn Trident3 switches running Cumulus Linux 4.3.1, NVIDIA validates the VLAN scale limit for VXLAN deployments with 8500 VLANs across ports with LACP bypass disabled. | 4.3.1-4.4.5 | |
| 3163845 | If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. | 4.3.1-4.4.5 | |
| 3138746 | The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3131423 | During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3129819 | On the EdgeCore AS4610 switch, the clagd service loses communication after 198 days of uptime. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3119615 | In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.10.1 |
| 3117340 | When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service. To recover, restart the networking service with the sudo systemctl restart networking command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3093966 | On Broadcom switches, INPUT chain iptable rules filter IPv6 packets matching the rules. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3093863 | The snmpd process will slowly leak memory when you poll TCP-MIB objects. To work around this issue, restart the snmpd service to free memory with the systemctl restart snmpd command. | 3.7.16-4.4.3 | 4.4.4-4.4.5, 5.2.0-5.10.1 |
| 3089165 | A slow memory leak might occur in switchd} if the route fails to install in hardware when hardware resources are exhausted. | 4.2.1-4.4.3 | 4.4.4-4.4.5 |
| 3084027 | Under a high load, you might see ingress drop counters increase. The drops are classified as HwIfInDiscards in ethtool and shown as ingress_general in hardware. | 4.3.0-4.4.5, 5.0.0-5.10.1 | |
| 3073668 | On the EdgeCore AS4610 switch, when you change the speed of any of the SFP+ ports, the other SFP+ ports flap. | 3.7.12-3.7.16, 4.3.0-4.4.5 | |
| 3072613 | When you delete a bond interface with NCLU, BGP peer group configuration is removed. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3059135 | In an OSPF configuration, after you change the IPv6 subnet mask, the old address remains in the RIB as a connected OSPF route To resolve this issue, restart FRR with the sudo systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3046023 | The cl-resource-query command output shows ECMP nextHop Table exhaustion (above 100 percent utilization) and the switchd.log file contains ECMP resource errors with routes and next hops failing to install. | 4.2.1-5.1.0 | 5.2.0-5.10.1 |
| 3007564 | After you delete the last vxlan-remoteip configuration line from the /etc/network/interfaces file and run the ifreload -a command, the corresponding BUM flood entry is not removed. | 3.7.15-5.0.1 | 5.1.0-5.10.1, 5.2.0-5.10.1 |
| 2999341 | CVE-2021-3570The ptp4l program in linuxptp, an implementation of the Precision Time Protocol (PTP), does not validate the messageLength field of incoming messages, allowing a remote attacker to cause a denial of service, information leak, or potentially remote code execution Fixed: 1.9.2-1+deb10u1 | 4.2.1-4.4.1 | 4.4.2-4.4.5 |
| 2968495 | If switchd requires more time to update port or bond configuration after the port or bond flaps, the systemd watchdog times out. As result, systemd might assume that switchd is unresponsive and restarts it. | 4.2.1-4.4.2 | 4.4.3-4.4.5, 5.1.0-5.10.1 |
| 2961008 | SNMP reports the same ifType of ethernetCsmacd(6) for loopback interfaces. | 3.7.15-4.4.2, 5.0.0-5.0.1 | 4.4.3-4.4.5, 5.1.0-5.10.1 |
| 2951110 | The net show time ntp servers command does not show any output with the management VRF. | 3.7.15-3.7.16, 4.1.1-4.4.5, 5.0.0-5.10.1 | |
| 2940051 | In an MLAG configuration with traditional bridges, MAC addresses are seen over peer link during ifreload when adding new VLANS or bridges. | 3.7.14.2-3.7.15, 4.3.0-4.4.5 | 3.7.16, 5.0.0-5.10.1 |
| 2902013 | The NCLU commit command adds a five second delay. | 4.2.1-4.4.5 | |
| 2896450 | On the Dell N3248PXE switch, fixed RJ45 interfaces with PoE neighbors can end up in Paused mode after a switchd restart, which blocks traffic on that interface. To work around this issue, restart switchd a second or third time until all interfaces are functioning correctly, or reboot the switch. | 4.3.0-4.4.5 | |
| 2893895 | CVE-2020-35498: A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service.

| 2854787 | An unexpected software system shutdown can occur due to a thermal zones issue in the hw-management package. The following message might appear in /var/log/syslog before the shutdown:thermal thermal_zoneX: critical temperature reached (33 C), shutting down | 4.3.0-4.3.3 | 4.4.0-4.4.5, 5.1.0-5.10.1 |
| 2854784 | After building VLAN or VXLAN interfaces, MLAG becomes unstable. | 4.3.0-4.4.1 | 4.4.2-4.4.5, 5.0.0-5.10.1 |
| 2845531 | If you update the MAC address of an SVI when the SVI is in a protodown state (for example, when no bridge ports that carry this VNI are operationally up or if the MAC address of the SVI’s parent bridge changes), clagd does not notice the change. The MLAG peer incorrectly maintains a PERMANENT neighbor entry for the SVI IP that points to the old MAC address. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 2838905 | On Broadcom ARM switches, the NTP clock slowly drifts to a very high offset (over 500ms) and the clock is not able to synchronize. To work around this issue, use the chrony implementation of NTP instead of ntpd. chrony synchronizes the system clock faster and with better accuracyInstructions for using chrony are here : https://docs.nvidia.com/networking-ethernet-software/knowledge-base/Network-Solutions/Chrony-on-Cumulus-Linux/ | 4.3.0-4.4.5 | |
| 2821869 | The cl-route-check –layer3 command fails with a memory error. For example:cumulus@switch:~$ sudo cl-route-check –layer3Traceback (most recent call last): | 3.7.15-4.4.5 | 5.0.0-5.10.1 |
| 2820565 | SNMP does not start and you see errors similar to the following:cumulus@switch:~$ sudo systemctl status snmpd.service snmpd.service - Simple Network Management Protocol (SNMP) Daemon.To work around this issue, run the sudo systemctl restart snmpd.service command. | 4.3.0-4.4.5 | 5.0.0-5.10.1 |
| 2794766 | The Mellanox 3700C switch reports a slow memory leak in sx_sdk. Memory increases by about 240B/hour and does not free up. | 4.3.0-4.4.5 | 5.0.0-5.10.1 |
| 2792616 | If a neighbor entry (ARP or NDP) is used as a next hop of a route that is synchronized into hardware, the neighbor entry is not removed from hardware after the neighbor is no longer reachable. As a result, routed traffic matching this prefix is incorrectly hardware forwarded through the stale neighbor information. | 4.3.0-4.4.5 | 5.0.0-5.10.1 |
| 2783611 | If you remove ports from a bridge and add IP addresses in one ifreload, connected routes are bound to the wrong routing information field. | 4.3.0-4.4.1 | 4.4.2-4.4.5 |
| 2782033 | The following vulnerabilities have been announced in the openssl packages:CVE-2021-3711: buffer overflow vulnerability in SM2 decryption CVE-2021-3712: buffer overrun when processing ASN.1 strings in the X509_aux_print() function More details at https://www.openssl.org/news/secadv/20210824.txt Vulnerable: <= 1.1.1d-0+deb10u6Fixed: 1.1.1d-0+deb10u7 | 4.0.0-4.4.1 | 4.4.2-4.4.5 |
| 2781537 | In Cumulus VX, the iptables FORWARD chain does not count hits. To work around this issue, use -t mangle -A PREROUTING instead of FORWARD. | 4.3.0-4.4.5 | 5.0.0-5.10.1 |
| 2771871 | IPv4 and IPv6 neighbor entries in a FAILED state are incorrectly programmed into hardware as FORWARD entries instead of TRAP entries.

| 2555613 | The net show configuration commands command incorrectly displays the NCLU syntax to disable IPv6 forwarding on interfaces. For example:
The correct NCLU command to disable IPv6 forwarding is net add vlan 1 ipv6 forward off (without the hyphen). | 4.2.1-4.4.5 | |
| 2555318 | If you try to enable BGP graceful restart when it is already enabled, you see an error similar to the following in the frr.log file:

| 2554812 | If the RMAC of a layer 3 SVI changes, the show vrf vni command is not updated with the new value. However, the new RMAC is seen in the show evpn vni command and is present on self-originated EVPN routes. | 4.2.1-4.4.5 | |
| 2554783 | If you apply an outbound route map to a BGP peer that uses set as-path prepend last-as, advertised locally-originated routes have the ASN of the peer prepended to the AS path.This might trigger AS path loop prevention on the peer, where the peer ignores locally-originated prefixes. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 2554709 | The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. | 3.7.13-3.7.16, 4.2.1-4.4.5 | |

| 2553989 | Default policer configured for LACP as an INPUT chain rule in 00control_plane.rules is meant to protect CPU from an LACP storm. When LACP storm is originating out of a single bond or bond member interface in a switch with multiple bond interfaces, there is a possibility of other LACP bond interface(s) going down. | 4.2.1-4.4.5 | |
| 2553887 | When using TACACS+ configured with a DEFAULT user providing privilege level lower than 16, TACACS+ configured users with privilege level 16 access might not be able to run privilege level 16 NCLU commands, such as net add and net del and see an error similar to the following:
To work around this issue, remove the DEFAULT user from the TACACS+ server. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2553677 | When you configure an SNMPv3 user with the net-snmp-config configuration command from the libsnmp-dev package, you get an error message similar to the one below:
To work around this issue, use the NCLU command to configure SNMPv3 user parameters; for example:
Alternatively, directly edit the /etc/snmp/snmpd.conf file as described in the documentation. | 3.7.13-3.7.16, 4.0.0-4.4.5 | |
| 2553237 | The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. | 4.2.0-4.4.5 | |
| 2553116 | When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition. Avoid setting the interface speed or duplex mode directly with ethtool. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2553015 | If a neighbour contains a special character in PortID for LLDP, the net show interface command does not display the LLDP information or the command might fail. | 3.7.10-3.7.16, 4.2.0-4.4.5 | |
| 2552691 | On the EdgeCore AS4610 switch, the eth0 interface remains down when physically connected to a 1G interface. To work around this issue, configure the link speed to 1000 and set auto-negotiation on for the eth0 interface, then flap eth0 with the ip link set eth0 down/up command to bring up the port. | 4.2.0-4.4.5 | |
| 2552453 | On the Mellanox switch, RoCE with PFC configuration is not applied to all ports in hardware when a range is used in the traffic.conf file.To work around this issue, use NCLU to configure RoCE with PFC or list individual ports in the traffic.conf file. | 4.2.0-4.4.5 | |

| 2552266 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.7.14-3.7.16, 4.0.0-4.4.5 | |
| 2551666 | If you modify an interface name, then reuse the previous interface name for a different VLAN, the ifreload -a command generates an error similar to the following:
| 4.1.0-4.4.5 | |
| 2551578 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2551565 | If you toggle VRRP priority values between VRRP routers, then restart switchd, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affectedTo work around this issue, remove, then add back the VRRP configuration with NCLU or vtysh commands. | 3.7.13-3.7.16, 4.2.0-4.4.5 | |
| 2551335 | When TACACS+ is configured and the management VRF is enabled, users with privilege level 13 are prevented from running ip and cat commands. | 4.0.0-4.4.5 | |

| 2551273 | On a Mellanox SN2010 switch, the Locator LED is on after you upgrade Cumulus Linux. | 4.1.0-4.4.5 | |
| 2551221 | When span-to-cpu is enabled on L3 swp interface with an IP address configured, packets with destination IP as switchport’s IP address don’t reach switchport. To capture packets directed towards switcport’s IP, disable span-to-cpu and use tcpdump on swichport instead. | 4.2.0-4.4.5 | |
| 2551111 | If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. | 4.0.0-4.4.5 | |
| 2550974 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.16, 4.1.1-4.4.5 | |

| 2550444 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550443 | The net show rollback description command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550243 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:

| 2546225 | When you execute the following command on the Delta AG6248C switch, the switch reboots and then comes right back into Cumulus Linux without installing the new image. The install image is still in /var/lib/cumulus/installer, which causes issues with cl-support.
To work around this issue, use the onie-select command to access ONIE, and then use the nos-install command in ONIE to install a new binary image. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546131 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |

| 2543841 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.16, 4.0.0-4.4.5 | |
| 2543816 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11, 4.0.0-4.4.5 | 3.7.12-3.7.16 |
| 2543781 | NCLU does not allow you to configure OSPF NSSAs. For example:
To work around this issue, use FRR instead. For example:
| 3.7.7-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543724 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:
| 3.7.7-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543646 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2543401 | On the Mellanox Spectrum-2 switch, the time required to establish a link (from the time a link is set to admin up until the link becomes operationally up) can take up to 15 seconds on 40G interfaces and up to 30 seconds on 100G interfaces.To work around this issue, wait up to 15 seconds on 40G interfaces and 30 seconds on 100G interfaces for the link to establish. | 4.0.0-4.4.5 | |
| 2543211 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2543164 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2543096 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542945 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:
| 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542837 | On Mellanox switches, policer iptables are not working as expected. For example, when using a policer with mode KB/MB/GB to rate-limit interfaces, the syntax is accepted but the data plane transfer speed is not affected by the rule. | 3.7.6-3.7.8, 4.0.0-4.4.5 | 3.7.9-3.7.16 |
| 2542305 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542301 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2541212 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2541029 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540753 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:
| 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540444 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540274 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540204 | When links come up after FRR is started, VRF connected routes do not get redistributed. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540192 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540155 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2540042 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto lines exist. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2539994 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539962 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2539670 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539124 | The net add interface command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538590 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2537699 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2537544 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2536576 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 4.0.0-4.4.5 | |
| 2536384 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 4.0.0-4.4.5 | |
| 2536242 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 4.0.0-4.4.5 | |
| 2535209 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.7.5-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2534734 | Span rules matching the out-interface as a bond do not mirror packets. | 4.0.0-4.4.5 | |
| 2533691 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 4.0.0-4.4.5 | |
| 2533337 | When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. | 4.0.0-4.4.5 | |
| 2531273 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. | 4.0.0-4.4.5 |
Fixed Issues in 4.3.2
| Issue ID | Description | Affects |
|---|---|---|
| 3647731 | CVE-2023-38408: The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009 Mitigation: Do not use ssh-agent forwarding (the man page for ssh_config says that “agent forwarding should be enabled with caution”), or start the ssh-agent program with the -P option to allow only specific PKCS#11 libraries (or none with -P ‘') For Cumulus Linux 4.3.2, the /usr/bin/ssh-agent program has all permissions turned off (chmod 0) to prevent its execution if a vulnerable version is detected. | 4.0.0-4.3.1, 5.0.0-5.6.0 |
| 3544701 | If BGP remote-as is set to an integer and you try to configure the local-as for a BGP instance, you see the following error:% AS specified for local as is the same as the remote as and this is not allowedThis configuration is not allowed; it is considered to be eBGP and local preference is not advertised. | 5.0.0-5.5.1 |
| 3534654 | On a Broadcom switch, Q-in-Q VLAN operations do not clear when you remove a bridge port from a VXLAN-enabled bridge. This can result in unexpected double tagged packets if the outer VLAN is still used on the bridge. To work around this issue, restart switchd after you modify or remove double tagged bridge ports from a VXLAN-enabled bridge. | 4.3.1 |
| 3497002 | When BGP receives an EVPN type-5 route with a gateway IP overlay attribute, the gateway IP overlay attribute in the attr memory (which is already inserted in the attribute hash) might change. As a result, the modified attr memory might match with another attr in the attribute hash, which produces duplicate entries in the hash table. As a result, BGP might crash when deleting one of the duplicate attr structures. | 4.3.0-4.3.1 |
| 3486888 | If FRR learns a layer 2 entry against a VNI and you reconfigure the VNI later as a layer 3 VNI, the original layer 2 entry does not clear and remains in the forwarding database. | 4.3.0-4.3.1 |
| 3479967 | When you remove VRF configuration, the systemctl reload frr.service command returns a non zero exit code after erroneously running the invalid command no exit-vrf. | 4.3.1 |
| 3455998 | When you poll the BGP unnumbered MIB object 1.3.6.1.4.1.40310.4 after uncommenting the bgpun_pp.py pass persist script in the /etc/snmpd/snmpd.conf file, BGP session information is not retrieved. To work around this issue, add executable permissions to the script with the sudo chmod +x /usr/share/snmp/bgpun_pp.py command. | 4.3.1 |
| 3448171 | If a default route is withdrawn from the routing table and then learned again, traffic matching this entry will be software (cpu) forwarded. This will cause intermittent drops due to the CPU the rate-limiter This only impacts the default VRF and a default route learned dynamically In order to recover from this condition: 1. Restart switchd.service (sudo systemctl restart switchd.service)OR 2. Reboot the switch (sudo reboot) | 4.3.1 |
| 3434315 | IPv6 BGP sessions in a VRF do not be establish with MD5 authentication. | 4.3.0-4.3.1 |
| 3419962 | On a Broadcom switch, if you remove a double-tagged interface from a bridge that contains other double-tagged interfaces built on the same physical port (for example, you remove swp1.10.100 when swp1.10.200 is also a bridge port), traffic forwarding within the bridge might fail and you see critical warnings in the /var/log/switchd.log file similar to the following:switchd[8587]: hal_bcm.c:2207 CRIT knet_vlan_translate_delete(update): port 1 ext_vlan 10.100 int_vlan 2132: -11 | 4.3.1 |
| 3419953 | If you remove a double tagged bridge port from a bridge when a different interface exists with the same port and virtual ID, you might see a segmentation fault and a switchd crash due to incorrect initialization when Cumulus Linux creates the second double-tagged interface. To work around this issue, make sure you remove the double-tagged interfaces from the bridge in the /etc/network/interfaces file. | 4.3.1 |
| 3413826 | During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. | 4.2.1-4.3.1, 4.4.0-5.4.0 |
| 3410952 | If MLAG is configured but disconnected from an MLAG peer for an extended period of time (days or more), there is a long delay (up to a minute per day) before traffic forwarding stabilizes after the MLAG peer connection re-establishes. | 3.7.0-4.3.1 |
| 3401121 | sFlow is not able to sample packets in the egress direction. To work around this issue, add the following to the hsflowd.conf file to enable egress sampling:samplingDirection=outpsample { group=1 } | 4.3.0-4.3.1 |
| 3376798 | On Broadcom switches, Cumulus Linux does not create the hardware bridging domain for a traditional bridge with a VXLAN interface during switchd restart. The /var/log/switchd.log file includes the following exception logs shortly after switchd restarts:switchd[30158]: hal_bcm_l3.c:1617 find_egr_path_if_vxlan_overlay:vxlan overlay : nh PORT: port <#>, vlanMAC learning looks correct, but traffic does not flow as expected. | 3.7.0-4.3.1 |
| 3366612 | The base version of the Linux kernel is updated to the v4.19.273 stable release, which includes fixes for several CVE issues. | 4.3.1 |
| 3364996 | Under certain conditions, BGP can allow a combination of EVPN and non-EVPN paths to be put into a multipath group together. This results in erroneous programming of EVPN symmetric next hops and RMACs, which can result in momentary traffic drops. | 4.3.0-4.3.1 |
| 3336590 | On the Trident 2+ and Trident 3 switch when using VXLAN layer 2 VPNs and sending tunneled traffic where the inner IP header has a TTL of 1, the egress VTEP incorrectly forwards this traffic through the software path instead of the hardware data plane. This traffic is rate-limited to 100pps by default. To work around this issue, ensure that the traffic traversing the layer 2 tunnel has an inner IP header TTL value that is more than 1. If this workaround is not possible, contact Nvidia Support to determine other options. | 4.3.0-4.3.1 |
| 3334036 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-4.3.1 |
| 3334031 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-4.3.1 |
| 3319919 | Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-4.3.1, 4.4.0-5.3.1 |
| 3288385 | On the EdgeCore AS7326-56X and AS7726-32X switch, the fan speed reports a minimum threshold in the logs. | 4.3.1 |
| 3288343 | When you reboot a Broadcom switch with a static default route configured, the route might be installed in hardware without a next hop. This results in forwarded traffic to the CPU and drops. To recover from this issue, remove the default route configuration and reapply it. To prevent this issue, before rebooting the switch, split the default route configuration into two routes as below:ip route 0.0.0.0/1 10.1.1.1ip route 128.0.0.0/1 10.1.1.1 | 4.3.1 |
| 3269538 | The cl-ecmpcalc command prints the following error when the egress interface is a bond or SVI:ecmpcalc: will query hardwareTraceback (most recent call last):File “/usr/cumulus/bin/cl-ecmpcalc”, line 986, inisTrunkMbr, port = ecmp.getHdPort(hd_cmd)File “/usr/cumulus/bin/cl-ecmpcalc”, line 618, in getHdPortport = int(str4)ValueError: invalid literal for int() with base 10: ‘0t | 4.3.0-4.3.1 |
| 3267353 | In a QinQ configuration, if the VLAN priority is a non-zero value, double-tagged packets are translated to triple-tagged packets. | 4.3.1 |
| 3244739 | If you have a lot of inbound route maps that match lists with many regex statements, a large number of updates from the peer can cause the system to run out of memory. To work around this issue, reduce the number of regex matches in inbound route maps. | 4.4.0-5.2.1 |
| 3236349 | Using ARP suppression with a very large number of interfaces might result in missing ARP entries on the local device or buffer underrun warnings in the neighmgrd log. | 4.3.0-4.3.1 |
| 3235956 | With certain triggers on Broadcom switches, such as adding or deleting a VNI or reloading the network, Cumulus Linux might consider the underlay routes as overlay routes. In this case, switchd allocates the overlay next hop, which is incorrect and might affect traffic forwarding. | 4.3.0-4.3.1 |
| 3234031 | If BGP neighbor is set, negating with no no neighbor does not disable the setting. To work around this issue and disable the setting, restart the FRR service. | 4.2.1-4.3.1 |
| 3191517 | When the switch receives an LLDP frame from a Cisco router right after a ptmd restart, the ptmd service crashes. | 4.3.0-4.3.1, 4.4.0-5.2.1 |
| 2555175 | Control plane traffic (such as BGP peering from leaf to spine) goes down on the leaf due to the peer Hold Down timer expiration following prolonged link flaps on down links when VXLAN enabled VLANs are carried on the flapping link. Be sure to correct layer 1 issues, configuration issues, or misbehaving link partners that are causing the link flaps. | 3.7.15-4.3.1 |

| 4037015 | The NVUE commands to delete SNMP users, and change authentication passwords and encryption passphrases are not successful. | 4.3.0-5.9.1 | 5.9.2-5.10.1, 5.10.0-5.10.1 |
| 3773177 | When you try to upgrade a switch from Cumulus Linux 5.5 or earlier to 5.8.0 or later with package upgrade, you see errors for expired GPG keys that prevent you from upgrading. To work around this issue, install the new keys with the following commands, then upgrade the switch.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/c/cumulus-archive-keyring/cumulus-archive-keyring_4-cl5.6.0u5_all.deb | 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3759932 | When you migrate virtual machines from one rack to another rack, there might be occasional problems reaching the server after Vmotion. | 4.3.1-4.3.2 | 4.3.3-4.4.5 |
| 3684998 | DHCP lease information is not collected in the cl-support file. | 4.3.0-5.6.0 | 5.7.0-5.10.1 |
| 3647731 | CVE-2023-38408: The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009 Mitigation: Do not use ssh-agent forwarding (the man page for ssh_config says that “agent forwarding should be enabled with caution”), or start the ssh-agent program with the -P option to allow only specific PKCS#11 libraries (or none with -P ‘') For Cumulus Linux 4.3.2, the /usr/bin/ssh-agent program has all permissions turned off (chmod 0) to prevent its execution if a vulnerable version is detected. | 4.0.0-4.3.1, 5.0.0-5.6.0 | 4.3.2-4.4.5, 5.7.0-5.10.1 |
| 3534654 | On a Broadcom switch, Q-in-Q VLAN operations do not clear when you remove a bridge port from a VXLAN-enabled bridge. This can result in unexpected double tagged packets if the outer VLAN is still used on the bridge. To work around this issue, restart switchd after you modify or remove double tagged bridge ports from a VXLAN-enabled bridge. | 4.3.1 | 4.3.2-4.4.5 |
| 3497002 | When BGP receives an EVPN type-5 route with a gateway IP overlay attribute, the gateway IP overlay attribute in the attr memory (which is already inserted in the attribute hash) might change. As a result, the modified attr memory might match with another attr in the attribute hash, which produces duplicate entries in the hash table. As a result, BGP might crash when deleting one of the duplicate attr structures. | 4.3.0-4.3.1 | 4.3.2-4.4.5, 5.6.0-5.10.1 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 | 5.6.0-5.10.1 |
| 3486888 | If FRR learns a layer 2 entry against a VNI and you reconfigure the VNI later as a layer 3 VNI, the original layer 2 entry does not clear and remains in the forwarding database. | 4.3.0-4.3.1 | 4.3.2-4.4.5, 5.6.0-5.10.1 |
| 3479967 | When you remove VRF configuration, the systemctl reload frr.service command returns a non zero exit code after erroneously running the invalid command no exit-vrf. | 4.3.1 | 4.3.2-4.4.5 |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 | 5.6.0-5.10.1 |
| 3455998 | When you poll the BGP unnumbered MIB object 1.3.6.1.4.1.40310.4 after uncommenting the bgpun_pp.py pass persist script in the /etc/snmpd/snmpd.conf file, BGP session information is not retrieved. To work around this issue, add executable permissions to the script with the sudo chmod +x /usr/share/snmp/bgpun_pp.py command. | 4.3.1 | 4.3.2-4.4.5 |
| 3448171 | If a default route is withdrawn from the routing table and then learned again, traffic matching this entry will be software (cpu) forwarded. This will cause intermittent drops due to the CPU the rate-limiter This only impacts the default VRF and a default route learned dynamically In order to recover from this condition: 1. Restart switchd.service (sudo systemctl restart switchd.service)OR 2. Reboot the switch (sudo reboot) | 4.3.1 | 4.3.2-4.4.5 |
| 3434315 | IPv6 BGP sessions in a VRF do not be establish with MD5 authentication. | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3429530 | On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.10.1 |
| 3419962 | On a Broadcom switch, if you remove a double-tagged interface from a bridge that contains other double-tagged interfaces built on the same physical port (for example, you remove swp1.10.100 when swp1.10.200 is also a bridge port), traffic forwarding within the bridge might fail and you see critical warnings in the /var/log/switchd.log file similar to the following:switchd[8587]: hal_bcm.c:2207 CRIT knet_vlan_translate_delete(update): port 1 ext_vlan 10.100 int_vlan 2132: -11 | 4.3.1 | 4.3.2-4.4.5 |
| 3419953 | If you remove a double tagged bridge port from a bridge when a different interface exists with the same port and virtual ID, you might see a segmentation fault and a switchd crash due to incorrect initialization when Cumulus Linux creates the second double-tagged interface. To work around this issue, make sure you remove the double-tagged interfaces from the bridge in the /etc/network/interfaces file. | 4.3.1 | 4.3.2-4.4.5 |
| 3413826 | During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. | 4.2.1-5.4.0 | 5.5.0-5.10.1 |
| 3410952 | If MLAG is configured but disconnected from an MLAG peer for an extended period of time (days or more), there is a long delay (up to a minute per day) before traffic forwarding stabilizes after the MLAG peer connection re-establishes. | 3.7.0-5.4.0 | 5.5.0-5.10.1 |
| 3401121 | sFlow is not able to sample packets in the egress direction. To work around this issue, add the following to the hsflowd.conf file to enable egress sampling:samplingDirection=outpsample { group=1 } | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3376798 | On Broadcom switches, Cumulus Linux does not create the hardware bridging domain for a traditional bridge with a VXLAN interface during switchd restart. The /var/log/switchd.log file includes the following exception logs shortly after switchd restarts:switchd[30158]: hal_bcm_l3.c:1617 find_egr_path_if_vxlan_overlay:vxlan overlay : nh PORT: port <#>, vlanMAC learning looks correct, but traffic does not flow as expected. | 3.7.0-4.3.1 | 4.3.2-4.4.5 |
| 3366612 | The base version of the Linux kernel is updated to the v4.19.273 stable release, which includes fixes for several CVE issues. | 4.3.1 | 4.3.2-4.4.5 |
| 3364996 | Under certain conditions, BGP can allow a combination of EVPN and non-EVPN paths to be put into a multipath group together. This results in erroneous programming of EVPN symmetric next hops and RMACs, which can result in momentary traffic drops. | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3336590 | On the Trident 2+ and Trident 3 switch when using VXLAN layer 2 VPNs and sending tunneled traffic where the inner IP header has a TTL of 1, the egress VTEP incorrectly forwards this traffic through the software path instead of the hardware data plane. This traffic is rate-limited to 100pps by default. To work around this issue, ensure that the traffic traversing the layer 2 tunnel has an inner IP header TTL value that is more than 1. If this workaround is not possible, contact Nvidia Support to determine other options. | 4.3.0-4.4.5 | |
| 3334036 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-4.3.1 | 4.3.2-4.4.5, 5.4.0-5.10.1 |
| 3334031 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3330705 | When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. | 3.7.0-5.3.1 | 5.4.0-5.10.1 |
| 3327477 | If you use su to change to a user specified through TACACS+, the user becomes the local tacacs0 thru tacacs15 user instead of the named user to run sudo commands. As a result, the named user password might not match the local tacacs0 thru tacacs15 user password. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.10.1 | |
| 3321391 | On the NVIDIA SN2410 switch, ports with optical transceivers show FAULT errors in the sensor command output. | 4.2.1-5.3.1 | 5.4.0-5.10.1 |
| 3319919 | Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-5.3.1 | 5.4.0-5.10.1 |
| 3291548 | In EVPN deployments, a buffer lockup for split or pre-split ports can occur on Spectrum-2 and Spectrum-3 switches. As result, traffic coming in on these ports is dropped in the RX buffer. To work around this issue, restart switchd. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 3288385 | On the EdgeCore AS7326-56X and AS7726-32X switch, the fan speed reports a minimum threshold in the logs. | 4.3.1 | 4.3.2-4.4.5 |
| 3288343 | When you reboot a Broadcom switch with a static default route configured, the route might be installed in hardware without a next hop. This results in forwarded traffic to the CPU and drops. To recover from this issue, remove the default route configuration and reapply it. To prevent this issue, before rebooting the switch, split the default route configuration into two routes as below:ip route 0.0.0.0/1 10.1.1.1ip route 128.0.0.0/1 10.1.1.1 | 4.3.1-4.4.5 | |
| 3269538 | The cl-ecmpcalc command prints the following error when the egress interface is a bond or SVI:ecmpcalc: will query hardwareTraceback (most recent call last):File “/usr/cumulus/bin/cl-ecmpcalc”, line 986, inisTrunkMbr, port = ecmp.getHdPort(hd_cmd)File “/usr/cumulus/bin/cl-ecmpcalc”, line 618, in getHdPortport = int(str4)ValueError: invalid literal for int() with base 10: ‘0t | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3267353 | In a QinQ configuration, if the VLAN priority is a non-zero value, double-tagged packets are translated to triple-tagged packets. | 4.3.1 | 4.3.2-4.4.5 |
| 3236349 | Using ARP suppression with a very large number of interfaces might result in missing ARP entries on the local device or buffer underrun warnings in the neighmgrd log. | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3235956 | With certain triggers on Broadcom switches, such as adding or deleting a VNI or reloading the network, Cumulus Linux might consider the underlay routes as overlay routes. In this case, switchd allocates the overlay next hop, which is incorrect and might affect traffic forwarding. | 4.3.0-4.3.1 | 4.3.2-4.4.5 |
| 3234031 | If BGP neighbor is set, negating with no no neighbor does not disable the setting. To work around this issue and disable the setting, restart the FRR service. | 4.2.1-4.3.1 | 4.3.2-4.4.5, 5.3.0-5.10.1 |
| 3218207 | Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 | 5.3.0-5.10.1 |
| 3216922 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users). | 3.7.0-5.2.1 | 5.3.0-5.10.1 |
| 3216921 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-3.7.16, 4.3.0-4.4.5 | |
| 3216759 | With the ip-acl-heavy TCAM profile, the following message might appear after you install an ACL with NCLU or cl-acltool and the ACL might not work correctlyhal_flx_acl_util.c:378 ERR hal_flx_acl_resource_release resource region 0 size 7387 create failed: No More ResourcesTo work around this issue, change the TCAM profile to acl-heavy or ip-acl-heavy with ACL non-atomic mode. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3191517 | When the switch receives an LLDP frame from a Cisco router right after a ptmd restart, the ptmd service crashes. | 4.3.0-5.2.1 | 5.3.0-5.10.1 |
| 3168564 | In a large scale VXLAN configuration (for example if you have more than 8500 VLANs across ports), switchd might crash when you restart clagd or when all bonds go operationally down, then upOn Trident3 switches running Cumulus Linux 4.3.1, NVIDIA validates the VLAN scale limit for VXLAN deployments with 8500 VLANs across ports with LACP bypass disabled. | 4.3.1-4.4.5 | |
| 3163845 | If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. | 4.3.1-4.4.5 | |
| 3138746 | The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3131423 | During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3129819 | On the EdgeCore AS4610 switch, the clagd service loses communication after 198 days of uptime. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3119615 | In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.10.1 |
| 3117340 | When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service. To recover, restart the networking service with the sudo systemctl restart networking command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3093966 | On Broadcom switches, INPUT chain iptable rules filter IPv6 packets matching the rules. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3093863 | The snmpd process will slowly leak memory when you poll TCP-MIB objects. To work around this issue, restart the snmpd service to free memory with the systemctl restart snmpd command. | 3.7.16-4.4.3 | 4.4.4-4.4.5, 5.2.0-5.10.1 |
| 3089165 | A slow memory leak might occur in switchd} if the route fails to install in hardware when hardware resources are exhausted. | 4.2.1-4.4.3 | 4.4.4-4.4.5 |
| 3084027 | Under a high load, you might see ingress drop counters increase. The drops are classified as HwIfInDiscards in ethtool and shown as ingress_general in hardware. | 4.3.0-4.4.5, 5.0.0-5.10.1 | |
| 3073668 | On the EdgeCore AS4610 switch, when you change the speed of any of the SFP+ ports, the other SFP+ ports flap. | 3.7.12-3.7.16, 4.3.0-4.4.5 | |
| 3072613 | When you delete a bond interface with NCLU, BGP peer group configuration is removed. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3059135 | In an OSPF configuration, after you change the IPv6 subnet mask, the old address remains in the RIB as a connected OSPF route To resolve this issue, restart FRR with the sudo systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.10.1 |
| 3046023 | The cl-resource-query command output shows ECMP nextHop Table exhaustion (above 100 percent utilization) and the switchd.log file contains ECMP resource errors with routes and next hops failing to install. | 4.2.1-5.1.0 | 5.2.0-5.10.1 |
| 3007564 | After you delete the last vxlan-remoteip configuration line from the /etc/network/interfaces file and run the ifreload -a command, the corresponding BUM flood entry is not removed. | 3.7.15-5.0.1 | 5.1.0-5.10.1, 5.2.0-5.10.1 |
| 2999341 | CVE-2021-3570The ptp4l program in linuxptp, an implementation of the Precision Time Protocol (PTP), does not validate the messageLength field of incoming messages, allowing a remote attacker to cause a denial of service, information leak, or potentially remote code execution Fixed: 1.9.2-1+deb10u1 | 4.2.1-4.4.1 | 4.4.2-4.4.5 |
| 2968495 | If switchd requires more time to update port or bond configuration after the port or bond flaps, the systemd watchdog times out. As result, systemd might assume that switchd is unresponsive and restarts it. | 4.2.1-4.4.2 | 4.4.3-4.4.5, 5.1.0-5.10.1 |

| 2556369 | If you use NCLU to configure an ACL for eth0, you can’t designate it as an INPUT rule; the rule is automatically created as a FORWARD rule in the /etc/cumulus/acl/policy.d/50_nclu_acl.rules file.To work around this issue, manually create an ACL in the /etc/cumulus/acl/policy.d/ file with “-A INPUT -i eth0”. | 4.2.1-4.4.5 | |
| 2556082 | The NCLU net del vrf command does not delete a numbered VRF. For example:
| 4.2.1-4.4.5 | |
| 2556081 | You cannot set the time zone can with NCLU commands. | 4.1.1-4.4.5 | |
| 2555873 | On Mellanox switches, egress ACLs with VLAN keys do not filter layer 2 multicast or broadcast traffic. | 4.3.0-4.4.5 | |
| 2555763 | The NCLU net del bgp neighbor command does not delete the neighbor and displays an error similar to the following:
To work around this issue, use the FRR command to delete a neighbor. | 4.3.0-4.4.5 | |
| 2555613 | The net show configuration commands command incorrectly displays the NCLU syntax to disable IPv6 forwarding on interfaces. For example:
The correct NCLU command to disable IPv6 forwarding is net add vlan 1 ipv6 forward off (without the hyphen). | 4.2.1-4.4.5 | |
| 2555318 | If you try to enable BGP graceful restart when it is already enabled, you see an error similar to the following in the frr.log file:
This error has no functional impact. | 4.3.0-4.4.5 | |
| 2555175 | Control plane traffic (such as BGP peering from leaf to spine) goes down on the leaf due to the peer Hold Down timer expiration following prolonged link flaps on down links when VXLAN enabled VLANs are carried on the flapping link. Be sure to correct layer 1 issues, configuration issues, or misbehaving link partners that are causing the link flaps. | 3.7.15-4.3.1 | 4.3.2-4.4.5 |
| 2554986 | The ethtool utility doesn’t contain the latest values, as a result the Revision Compliance field shows Unallocated. | 4.2.1-4.4.5 | |
| 2554812 | If the RMAC of a layer 3 SVI changes, the show vrf vni command is not updated with the new value. However, the new RMAC is seen in the show evpn vni command and is present on self-originated EVPN routes. | 4.2.1-4.4.5 | |
| 2554783 | If you apply an outbound route map to a BGP peer that uses set as-path prepend last-as, advertised locally-originated routes have the ASN of the peer prepended to the AS path.This might trigger AS path loop prevention on the peer, where the peer ignores locally-originated prefixes. | 4.2.1-4.4.5 | 5.0.0-5.10.1 |
| 2554709 | The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. | 3.7.13-3.7.16, 4.2.1-4.4.5 | |
| 2554670 | When you have a large number of ACLs, the cl-acltool -L ip and cl-resource-query commands take a long time to complete. | 4.3.0-4.4.5 | |
| 2554582 | On switches with the Maverick ASIC, control traffic is dropped due to receive buffering. | 4.2.0-4.4.5 | |
| 2554533 | On the ARM platform, NTP peer associations slowly increase to larger offsets (~500ms). | 4.0.0-4.4.5 | |
| 2554466 | Kernel routes added by iproute2 are missing in FRR after an interface flap.To work around this issue, configure a static route in FRR. | 4.2.1-4.4.5 | |
| 2554299 | In a VRRP configuration, BGP unnumbered sessions for VRFs fail to establish after a networking restart. | 4.2.0-4.3.3 | 4.4.0-4.4.5 |
| 2554222 | The NCLU command to enable bridge learning fails. As a work around, enable bridge learning in the /etc/network/interface file. For example:
| 4.2.1-4.4.5 | |
| 2554218 | MLAG packets received on the peer link are dropped instead of routed. | 4.2.0-4.4.5 | |
| 2554202 | The output of the net show commit command does not show the last commit or the specified commit number but is empty instead. | 4.2.1-4.4.5 | |
| 2553989 | Default policer configured for LACP as an INPUT chain rule in 00control_plane.rules is meant to protect CPU from an LACP storm. When LACP storm is originating out of a single bond or bond member interface in a switch with multiple bond interfaces, there is a possibility of other LACP bond interface(s) going down. | 4.2.1-4.4.5 | |
| 2553887 | When using TACACS+ configured with a DEFAULT user providing privilege level lower than 16, TACACS+ configured users with privilege level 16 access might not be able to run privilege level 16 NCLU commands, such as net add and net del and see an error similar to the following:
To work around this issue, remove the DEFAULT user from the TACACS+ server. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2553677 | When you configure an SNMPv3 user with the net-snmp-config configuration command from the libsnmp-dev package, you get an error message similar to the one below:
To work around this issue, use the NCLU command to configure SNMPv3 user parameters; for example:
Alternatively, directly edit the /etc/snmp/snmpd.conf file as described in the documentation. | 3.7.13-3.7.16, 4.0.0-4.4.5 | |
| 2553237 | The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. | 4.2.0-4.4.5 | |
| 2553116 | When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition. Avoid setting the interface speed or duplex mode directly with ethtool. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2553015 | If a neighbour contains a special character in PortID for LLDP, the net show interface command does not display the LLDP information or the command might fail. | 3.7.10-3.7.16, 4.2.0-4.4.5 | |
| 2552691 | On the EdgeCore AS4610 switch, the eth0 interface remains down when physically connected to a 1G interface. To work around this issue, configure the link speed to 1000 and set auto-negotiation on for the eth0 interface, then flap eth0 with the ip link set eth0 down/up command to bring up the port. | 4.2.0-4.4.5 | |
| 2552453 | On the Mellanox switch, RoCE with PFC configuration is not applied to all ports in hardware when a range is used in the traffic.conf file.To work around this issue, use NCLU to configure RoCE with PFC or list individual ports in the traffic.conf file. | 4.2.0-4.4.5 | |
| 2552309 | The following messages are seen on an Edgecord Minipack-AS8000 running Cumulus Linux 4.2.0:
These messages are for internal validation purposes only and can be safely ignored. | 4.2.0-4.4.5 | |
| 2552294 | NCLU restarts FRR when removing a BGP VRF IPv4 aggregate-address command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2552266 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.7.14-3.7.16, 4.0.0-4.4.5 | |
| 2551666 | If you modify an interface name, then reuse the previous interface name for a different VLAN, the ifreload -a command generates an error similar to the following:
| 4.1.0-4.4.5 | |
| 2551578 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2551565 | If you toggle VRRP priority values between VRRP routers, then restart switchd, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affectedTo work around this issue, remove, then add back the VRRP configuration with NCLU or vtysh commands. | 3.7.13-3.7.16, 4.2.0-4.4.5 | |
| 2551335 | When TACACS+ is configured and the management VRF is enabled, users with privilege level 13 are prevented from running ip and cat commands. | 4.0.0-4.4.5 | |
| 2551305 | The net show configuration command provides the wrong net add command for ACL under the VLAN interface. | 3.7.12-3.7.16, 4.1.0-4.4.5 | |
| 2551273 | On a Mellanox SN2010 switch, the Locator LED is on after you upgrade Cumulus Linux. | 4.1.0-4.4.5 | |
| 2551221 | When span-to-cpu is enabled on L3 swp interface with an IP address configured, packets with destination IP as switchport’s IP address don’t reach switchport. To capture packets directed towards switcport’s IP, disable span-to-cpu and use tcpdump on swichport instead. | 4.2.0-4.4.5 | |
| 2551111 | If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. | 4.0.0-4.4.5 | |
| 2550974 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.16, 4.1.1-4.4.5 | |
| 2550793 | The NCLU net show bridge spanning-tree command displays the aging timer incorrectly. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550713 | Configuring the subinterface of a VXLAN uplink under another traditional bridge, which also has the VXLAN VNI enslaved, causes switchd to use high CPU due to very frequent VXLAN tunnel sync events.To work around this issue, do not enslave the subinterface of a VXLAN layer 3 uplink under a traditional bridge in a VXLAN configuration. | 4.1.1-4.4.5 | |
| 2550704 | On the Mellanox SN3420 switch, 25G SR optics only link up in force mode. | 4.3.0-4.3.3 | 4.4.0-4.4.5 |
| 2550642 | ACLs with SPAN target and in-interface as bond member are not supported on Spectrum-based switches | 4.2.0-4.4.5 | |
| 2550444 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550443 | The net show rollback description command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550243 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:
| 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550056 | The ACCTON-DIAG option under the Cumulus Linux GRUB menu does not work. When you select this option, you see the following error:
| 3.7.12-3.7.16, 4.1.1-4.4.5 | |
| 2549925 | When you run an Ansible script to replace the /etc/network/interfaces file, then run the ifreload -a command, you see errors similar to the following:
To work around this issue, run the ifreload -a command a second time. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2549872 | If you have an SVI with multiple VRR IP addresses and try to delete one of the VRR configurations, net commit or ifreload -a returns an error. | 3.7.12-3.7.16, 4.1.1-4.4.5 | |
| 2549782 | The JSON format output of the net show bgp l2vpn evpn summary command shows the incorrect neighbour state. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2549731 | When you create SPAN or ERSPAN rules in ebtables, the action fails to install if it is not in lowercase. Make sure that the SPAN or ERSPAN action is all lowercase; for example:
| 3.7.12-3.7.16, 4.1.1-4.4.5 | |
| 2549392 | When you configure an RD or RT with NCLU, you see duplicate VNI stanzas in the /etc/frr/frr.conf file.To work around this issue, manually edit the etc/frr/frr.conf file to define advertise-all-vni before the RD or RT configuration within the l2vpn EVPN address family, then reload the FRR service with the sudo systemctl reload frr command. | 4.1.0-4.4.5 | |
| 2549371 | When Optimized Multicast Flooding (OMF) is enabled with the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/switchd.conf file, the switch continues to flood IPv6 multicast traffic to all slave ports when there is no MLD join receive. | 3.7.11-4.3.3 | 4.4.0-4.4.5 |
| 2548924 | On the EdgeCore Minipack AS8000, storm control does not restrict unknown unicast, broadcast, or multicast traffic. | 4.1.1-4.4.5 | |
| 2548657 | When you upgrade Cumulus Linux on the EdgeCore AS7726-32X or AS7326-56X switch, you might see firmware errors similar to the following:
You can safely ignore these error messages. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2548579 | The following security vulnerability has been announced: CVE-2020-10531: An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp. | 3.7.12, 4.0.0-4.4.5 | 3.7.13-3.7.16 |
| 2548315 | The following security advisory has been announced for bash: CVE-2019-18276 Qualys scan QID 372268 setuid vulnerability When bash or bash scripts are run setuid, bash is supposed to drop privileges, but does so incorrectly, so that an attacker with command access to the shell can use enable -f for runtime loading of a new builtin that calls setuid() to regain dropped privileges.To work around this issue, do not make bash or bash scripts setuid. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2548310 | When the system boots, we might see " cumulus systemd-udevd[7566]: Process ‘/usr/bin/hw-management-thermal-events.sh add thermal_zone /sys /devices/virtual/thermal/thermal_zone25 thermal_zone25’ failed with exit code 1" errors. These errors are result of user space acting on kernel events a bit slow. The mlxsw_minimal driver is added during kernel boot; An SDK reset causes the driver to be deleted and re-instantiated; User space handler for thermal zone add sees the add first; But the underlying device is deleted before it can act on it. This situation is rectified as the mlxsw_minimal driver is re-instantiated later; | 4.1.0-4.4.5 | |

| 2548117 | In OVSDB traditional bridge mode, adding or removing a VLAN binding causes a traffic forwarding outage for around 20 seconds or more on adjacent VLAN bindings. Cumulus Linux does not support traditional bridge mode with VMware NSX. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2548062 | When ports are split to 4x25G, RS FEC needs to explicitly configured on both ends (especially when interoperating with non-Mellanox switches). | 4.1.0-4.4.5 | |
| 2548044 | When a remote VTEP withdraws a type-3 EVPN route, Cumulus Linux purges all MAC address and neighbor entries installed in the corresponding layer 2 VNI through that remote VTEP from the local EVPN and kernel forwarding tables. This purge occurs even if the remote VTEP does not withdraw type-2 routes carrying the MAC address or neighbor entries. The entries stay missing from the local EVPN and kernel forwarding tables until BGP updates the MAC address and neighbor. | 3.7.12-3.7.15, 4.0.0-4.4.5 | 3.7.16 |

| 2546225 | When you execute the following command on the Delta AG6248C switch, the switch reboots and then comes right back into Cumulus Linux without installing the new image. The install image is still in /var/lib/cumulus/installer, which causes issues with cl-support.
To work around this issue, use the onie-select command to access ONIE, and then use the nos-install command in ONIE to install a new binary image. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546131 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |

| 2544311 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2544155 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2544113 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2543937 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543915 | When you enable a service in the management VRF, systemctl issues a warning similar to the following:Warning: The unit file, source configuration file or drop-ins of ntp@mgmt.service changed on disk. Run ‘systemctl daemon-reload’ to reload unitYou can safely ignore this warning. | 4.0.0-5.9.2 | 5.10.0-5.10.1 |
| 2543900 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.16, 4.0.0-4.4.5 | |
| 2543841 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.16, 4.0.0-4.4.5 | |
| 2543816 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11, 4.0.0-4.4.5 | 3.7.12-3.7.16 |
| 2543781 | NCLU does not allow you to configure OSPF NSSAs. For example:
To work around this issue, use FRR instead. For example:
| 3.7.7-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543724 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:
| 3.7.7-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2543646 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2543401 | On the Mellanox Spectrum-2 switch, the time required to establish a link (from the time a link is set to admin up until the link becomes operationally up) can take up to 15 seconds on 40G interfaces and up to 30 seconds on 100G interfaces.To work around this issue, wait up to 15 seconds on 40G interfaces and 30 seconds on 100G interfaces for the link to establish. | 4.0.0-4.4.5 | |
| 2543211 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2543164 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2543096 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542945 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:
| 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542837 | On Mellanox switches, policer iptables are not working as expected. For example, when using a policer with mode KB/MB/GB to rate-limit interfaces, the syntax is accepted but the data plane transfer speed is not affected by the rule. | 3.7.6-3.7.8, 4.0.0-4.4.5 | 3.7.9-3.7.16 |
| 2542305 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542301 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2541212 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2541029 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540753 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:
| 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540444 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540274 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540204 | When links come up after FRR is started, VRF connected routes do not get redistributed. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540192 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540155 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2540042 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto lines exist. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2539994 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539962 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2539670 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539124 | The net add interface command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538590 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2537699 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2537544 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2536576 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 4.0.0-4.4.5 | |
| 2536384 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 4.0.0-4.4.5 | |
| 2536242 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 4.0.0-4.4.5 | |
| 2535209 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.7.5-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2534734 | Span rules matching the out-interface as a bond do not mirror packets. | 4.0.0-4.4.5 | |
| 2533691 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 4.0.0-4.4.5 | |
| 2533337 | When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. | 4.0.0-4.4.5 | |
| 2531273 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. | 4.0.0-4.4.5 |
Fixed Issues in 4.3.1
| Issue ID | Description | Affects |
|---|---|---|
| 3216915 | Cumulus Linux 4.3.1 is available for Broadcom switches only. Do not upgrade a Mellanox switch to Cumulus Linux 4.3.1 On Broadcom switches, upgrading from Cumulus Linux 4.3.0 to CumulusLinux-4-latest with apt update and apt upgrade downloads and installs only the cumulus-newpackages-bcm package. This changes CumulusLinux-4-latest in the /etc/apt/sources.list to CumulusLinux-4-latest-BCM after which, when you run apt update and apt upgrade, the switch upgrades to Cumulus Linux 4.3.1On Broadcom switches, upgrading from Cumulus Linux 4.0.0 to 4.2.1 to CumulusLinux-4-latest with apt update and apt upgrade will upgrade to CumulusLinux 4.3.0, with CumulusLinux-4-latest-BCM listed in /etc/apt/sources.list. Doing apt update and apt upgrade again will then upgrade the switch to Cumulus Linux 4.3.1For Mellanox switches, the above procedure does not upgrade to Cumulus Linux 4.3.1. However, if you start the upgrade from Cumulus Linux 4.0.0 to 4.2.1, the switch might upgrade to Cumulus Linux 4.3.0. | |
| 3209699 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-4.3.0, 4.4.0-5.2.1 |
| 3185796 | When you enable ACL nonatomic update mode in the /etc/cumulus/switchd.conf file, the switch starts dropping ICMPv6 neighbor advertisement packets, which leads to an outage because the attached hosts are unable to communicate with each other. | 4.3.0 |
| 3138137 | The OID 1.3.6.1.4.1.40310.4.3.1.1.5 doesn’t return all BGP unnumered interfaces. To workaround this issue, avoid multiple BGP sessions to routers using the same ID. If you have multiple peering sessions across subinterfaces that live in distinct VRFs, configure a separate router ID per VRF. If there are multiple peering sessions to the same device in the same VRF, consider consolidating into a single BGP session by either peering across a bond or by using a multi hop session between loopbacks. | 4.3.0 |
| 3136940 | The clagd process uses 100 percent CPU and eventually crashes with an Unable to allocate memory error. | 4.3.0 |
| 3120423 | When you configure an interface in FRR to send IPv6 RAs before you configure the interface in the /etc/network/interfaces file, the switch does not process IPv6 RAs. To work around this issue, remove the interface configuration in FRR and reapply it. | 3.7.15-4.3.0, 4.4.0-5.1.0 |
| 3110729 | When you change the time with NTP or manually, the clagd service stops. | 4.3.0 |
| 3089474 | The clagd process uses 100 percent CPU and eventually crashes with an Unable to allocate memory error. | 4.3.0 |
| 3068962 | Cumulus Linux installation fails with the error Installation Problems, sub-task Installing Optional Packages. This occurs because the web server hosting the Cumulus Linux image remaps a 404 for a non-existent file image.optional_pkgs into a web page, which it then incorrectly attempts to use as a list of optional packagesTo work around this issue, on the web server hosting the image, create an empty file with the same name as the image with .optional_pkgs appended to the name. | 4.4.0-4.4.3 |
| 3066704 | The hostapd service stops working if an 802.1X interface goes up and down many times over a long period of timeTo work around this issue, restart the hostapd service with the systemctl restart hostapd command. | 3.7.15-4.3.0 |
| 3053063 | The update-ports.service fails because a blank space in the comment lines of the /etc/cumulus/ports.conf file causes parsing errorsTo work around this issue, remove the blank spaces in the commented lines, then restart the update-ports and switchd services. | 3.7.15-4.3.0 |
| 3031235 | In a static VXLAN configuration with a traditional or single VXLAN device, enabling bridge learning on the VNI leads to an incorrect warning and the setting is removed in the next commit. The warning is similar to the following:warning: vni10: possible mis-configuration detected: l2-vni configured with bridge-learning ON while EVPN is also configured - these two parameters conflict with each other | 4.3.0 |
| 3020254 | When ARP suppression is off, Cumulus Linux sends GARPs from neighmgrd for remote neighbors over VXLAN. | 3.7.15-4.3.0, 4.4.0-4.4.3, 5.0.0-5.1.0 |
| 2993469 | If you remove NGINX from the switch, then run apt autoremove, switchd does not reload because the libyaml-0-2 and python-yaml packages are missing; these packages are required for switchd consistency checking. To work around this issue, reinstall the libyaml-0-2 and python-yaml packages. | 4.3.0 |
| 2991514 | Cumulus Linux can take a long time (100 seconds) to sync a large number of VNIs on a bridge. | 3.7.15-4.3.0 |
| 2991501 | When you poll TCP-MIB objects, the snmpd process slowly leaks memory. To work around this issue, restart the snmpd service to free memory with the systemctl restart snmpd command. | 4.3.0 |
| 2949512 | On the EdgeCore AS4610-54T switch, the fan speed reports a minimum threshold in the logs. | 4.3.0 |
| 2943222 | Cumulus Linux lets you add more than one VXLAN interface to same VLAN on the same bridge. This is an invalid configuration as certain Cumulus Linux components, such as switchd, expect a single VNI for a given bridge or VLAN. | 3.7.15, 4.2.1-4.3.0, 4.4.2-5.0.1 |
| 2935121 | When you configure 199 VXLANs plus 199 VLANs, clagd crashes every few seconds. | 3.7.15, 4.3.0, 4.4.0-4.4.1 |
| 2932121 | When switchd restarts, the port watch daemon (portwd) attempts to send requests to switchd before switchd is ready. As a result, portwd goes into a failed state because there is no response from switchd. | 4.3.0 |
| 2906967 | You can’t have more than one VLAN subinterface on the same port on the same bridge. | 4.1.1-4.3.0 |
| 2899422 | Broadcom switches return a table full error when creating VXLAN gports, which causes {switchd to crash. | 3.7.15-4.3.0 |
| 2896733 | Traffic failover in a multicast topology with redundancy has the mroute stuck in a prune state and PIM join messages continue to send. To work around this issue, run the vtysh clear ip mroute command. | 3.7.15-4.3.0, 5.0.0-5.0.1 |
| 2875337 | In a scaled EVPN-MLAG configuration (observed with 400 or more VNIs and 20K or more MAC addresses – the actual scale might vary), when the peer link flaps causing all VNIs to come up at the same time, there might be high CPU utilization on the system for several minutes and the FRR service might restart. After FRR restarts or the CPU utilization settles down, the system functions normally. | 4.2.1-4.3.0, 4.4.0-5.0.1 |
| 2875301 | When an IPv4 address is not configured on a tenant VRF loopback interface, the switchd process slowly leaks memory, which results in unresolved next hops. To work around this issue, configure an IPv4 address on all VRF interfaces. | 4.3.0 |
| 2875296 | On a Mellanox Spectrum-2 switch, after running the systemctl restart networking service command on the MLAG primary switch, the secondary switch also closes its ports. To work around this issue, run the ifreload -a command to restart networking. | 4.2.1-4.3.0 |
| 2867058 | On the Dell Z9264F-ON switch, interfaces that use the QSFP28 module remain down after you restart switchd. | 3.7.15-4.3.0 |

| 2815645 | In an EVPN configuration, an FRR restart on a border leaf VRRP master causes a stale route for the VRRP VIP on some remote VTEPs to point to the VRRP backup after convergence. | 3.7.12-3.7.15, 4.3.0, 4.4.2-5.0.1 |
| 2792750 | If you change the clagd-vxlan-anycast-ip setting on both MLAG peers at the same time, both peers use their unique VTEP address indefinitely. | 3.7.15-4.3.0, 4.4.0-4.4.5 |
| 2786264 | When the switchd service restarts, any dropped traffic registered by WJH change to unregistered and WJH stops reporting all dropped traffic. This occurs because the WJH service does not restart automatically when the switchd service restartsTo work around this issue, manually restart WJH with the sudo systemctl restart what-just-happened.service command every time the switchd service restarts. | 4.3.0 |
| 2770030 | When you modify the default pre-auth policy located in /etc/cumulus/acl/policy.d/dot1x_preauth_dacl, after restarting hostapd the /etc/cumulus/acl/policy.d/dot1x_preauth_dacl directory is deleted and recreated with the default rule set that comes from the hostapd binary. | 4.3.0 |
| 2754723 | When route_preferred_over_neigh is set to FALSE in the /etc/cumulus/switchd.conf file, host routes (/32 or /128) are used for forwarding in hardware instead of a local neighbor entry. | 4.0.0-4.3.0, 4.4.0-4.4.1 |
| 2739398 | Cumulus Linux does not support a bond or bond member as a SPAN destination. | 4.4.0-4.4.5 |
| 2738625 | When you configure the switch with the minimum reserved VLAN of 150 and the internal VLANs are exhausted, the MLAG peer does not forward the VLAN. | 3.7.15, 4.2.1-4.3.0 |

| 2724191 | On the Celestica Seastone switch, when you run smonctl -v, the DIMM 1 Temp Sensor shows as absentThis is a cosmetic software issue and not indicative of a hardware failure on the system. | 4.3.0 |
| 2716822 | The /etc/cumulus/ports.conf file on the Dell Z9264F-ON switch does not show that Cumulus Linux does not support the 2x10G SFP+ ports. | 3.7.15-4.3.0 |
| 2705160 | Zebra rejects MAC IP updates from BGP when the MAC mobility sequence number that BGP sends is lower than the sequence number known to zebra When the MAC mobility sequence that BGP knows legitimately lowers (due to narrow timing conditions during convergence or after rebooting an MLAG pair one VTEP at a time), zebra rejects these updates and maintains a stale state. If the stale information that zebra uses points to the wrong VTEP address, traffic goes to the wrong VTEP and might drop. | 4.0.0-4.3.0, 4.4.0-4.4.5 |
| 2700701 | A default route learned from DHCP on eth0 in the management VRF might install in the default VRF if eth0 is disconnected and the original next hop is reachable in the default VRF. To work around this issue, delete the DHCP lease file for eth0 with the sudo rm /var/lib/dhcp/dhclient.eth0.leases command. | 4.3.0 |
| 2699399 | When you run the vtysh show ip bgp vrf command, the bgpd service crashes if you use vrf all. For example:spine01# show ip bgp vrf all statistics vtysh: error reading from bgpd: Success (0)Warning: closing connection to bgpd because of an I/O error!To workaround this issue, run the command against each VRF independently. | 3.7.15, 4.0.0-4.3.0 |
| 2699378 | Following an event that causes the peer link bond MAC address to change, such as a slave port state change, MLAG interfaces might be suspended due to a peer-ip-mismatch. This behavior is seen when you use a clagd-peer-ip linklocal configuration. | 4.3.0 |
| 2695314 | In a VRRP configuration, BGP unnumbered sessions for VRFs fail to establish after a networking restart. | 4.3.0 |
| 2685584 | A host migrated to an 802.1x port within the same broadcast domain does not have the correct static FDB entry installed if a dynamic FDB entry for that MAC address exists from previous connectivity in the broadcast domain. | 4.2.1-4.3.0 |

| 2668543 | When configured with NVUE, SVIs do not inherit the pinned MAC address of the bridge. | 4.3.0 |
| 2663119 | If you update the MAC address of an SVI using ifreload and hwaddress, the kernel maintains a stale permanent fdb entry for the old MAC address. | 3.7.15, 4.3.0, 4.4.0-4.4.3, 5.0.0-5.0.1 |
| 2660583 | In an MLAG configuration, the secondary MLAG switch does not use a unique address instead of the MLAG system MAC address when there is a double-failure (peer link failure and backup IP failure) | 4.3.0 |
| 2654715 | The cl-acltool takes a significant amount of time to run, which can slow down automation scripts. | 4.2.0-4.3.0 |
| 2652003 | When 802.1x MAB and a parking VLAN are configured on an interface, hostapd might install a static FDB entry if the interface is down. To work around this issue, delete 802.1x from the interface with the net del interface command, then add back the 802.1x configuration. | 3.7.10-4.3.0 |
| 2645609 | The NCLU net show route vrf and vtysh show [ip|ipv6] route vrf commands do not return any output. | 4.3.0 |
| 2644071 | When you stop clagd on the MLAG primary switch (for example, when you reboot the switch), in rare conditions the MLAG secondary switch might fail to properly assert itself as the MLAG primary switch. To work around this issue, change the primary designation by configuring the clagd priorities to ensure that you only reboot a switch that is in the MLAG secondary role. | 3.7.15, 4.3.0 |
| 2633062 | The following vulnerability affects the libgstreamer-plugins-base1.0-0 package. There is no CVE yet; the Debian advisory number is DSA-4903-1 Multiple vulnerabilities were discovered in plugins for the GStreamer media framework, which may result in denial of service or potentially the execution of arbitrary code if a malformed media file is opened Vulnerable: 1.14.4-2Fixed: 1.14.4-2+deb10u1 | 4.0.0-4.3.0 |
| 2628493 | On a PFC configured switch, non PFC enabled ports might transmit or receive traffic incorrectly after a reboot. To work around this issue, either run the echo 1 > /cumulus/switchd/config/traffic/reload command or the sudo systemctl restart switchd.service command. | 4.3.0 |
| 2613119 | The Mellanox 100G transceiver MMA1L30-CM Rev A3 is not recognized on the SN4600 switch even though the link is up. The ethtool output shows the error Cannot get Module EEPROM data: Invalid argument. | |
| 2556816 | When ARP suppression is enabled, RARP packets sometimes get dropped and are not flooded by the local VTEP. To work around this issue, disable ARP suppression. | 3.7.14-3.7.14.2, 4.3.0 |
| 2556775 | DSA-4859-1 (no CVE): zstd, a compression utility, was vulnerable to a race condition: it temporarily exposed, during a very short timeframe, a world-readable version of its input even if the original file had restrictive permissions. Vulnerable: <= 1.3.8+dfsg-3+deb10u1 Fixed: 1.3.8+dfsg-3+deb10u2 | 4.0.0-4.3.0 |

| 2556691 | The following vulnerabilities have been announced in the openssl packages: CVE-2021-23840: Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. CVE-2021-23841: The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. CVE-2019-1551: There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Vulnerable: <= 1.1.1d-0+deb10u4 Fixed: 1.1.1d-0+deb10u5 | 4.0.0-4.3.0 |

4.3.0 Release Notes
Open Issues in 4.3.0
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3351951 | Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-5.3.1 | 5.4.0 |
| 3336590 | On the Trident 2+ and Trident 3 switch when using VXLAN layer 2 VPNs and sending tunneled traffic where the inner IP header has a TTL of 1, the egress VTEP incorrectly forwards this traffic through the software path instead of the hardware data plane. This traffic is rate-limited to 100pps by default. To work around this issue, ensure that the traffic traversing the layer 2 tunnel has an inner IP header TTL value that is more than 1. If this workaround is not possible, contact Nvidia Support to determine other options. | 4.3.0-4.4.5 | |
| 3334036 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-5.3.1 | 5.4.0 |
| 3334031 | When you configure or unconfigure a BGP peer and interface towards a host, memory corruption can cause BGP to crash. | 4.3.0-4.4.5 | |
| 3330705 | When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. | 3.7.0-5.3.1 | 5.4.0 |
| 3330654 | When using TACACS+, if the /etc/nsswitch.conf file specifies passwd: files tacplus (files is listed before tacplus), the user name mapping might be incorrect; for example, the user name shown in the default prompt might be incorrect. When you use NVUE, this occurs when the priority for the authentication order of local is higher than tacacs. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.4.0 | |
| 3327477 | Using su to change to a user specified through TACACS+ results in becoming the local tacacs0 thru tacacs15 user instead of the named user to run sudo commands. When sudo asks for the password of the named user, it is unlikely to match that of the local tacacs0 thru tacacs15 user. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.4.0 | |
| 3291548 | In EVPN deployments, a buffer lockup for split or pre-split ports can occur on Spectrum-2 and Spectrum-3 switches. As result, traffic coming in on these ports is dropped in the RX buffer. To work around this issue, restart switchd. | 4.2.1-4.4.5 | 5.0.0-5.4.0 |
| 3269538 | The cl-ecmpcalc command prints the following error when the egress interface is a bond or SVI:ecmpcalc: will query hardwareTraceback (most recent call last):File “/usr/cumulus/bin/cl-ecmpcalc”, line 986, inisTrunkMbr, port = ecmp.getHdPort(hd_cmd)File “/usr/cumulus/bin/cl-ecmpcalc”, line 618, in getHdPortport = int(str4)ValueError: invalid literal for int() with base 10: ‘0t | 4.3.0-4.4.5 | |
| 3236349 | Using ARP suppression with a very large number of interfaces might result in missing ARP entries on the local device or buffer underrun warnings in the neighmgrd log. | 4.3.0-4.4.5 | |
| 3235956 | With certain triggers on Broadcom switches, such as adding or deleting a VNI or reloading the network, Cumulus Linux might consider the underlay routes as overlay routes. In this case, switchd allocates the overlay next hop, which is incorrect and might affect traffic forwarding. | 4.3.0-4.4.5 | |
| 3234031 | If BGP neighbor is set, negating with no no neighbor does not disable the setting. To work around this issue and disable the setting, restart the FRR service. | 4.2.1-5.2.1 | 5.3.0-5.4.0 |
| 3216922 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users). | 3.7.0-4.3.0, 4.4.0-5.2.1 | 4.3.1, 5.3.0-5.4.0 |
| 3216921 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-4.3.0, 4.4.0-4.4.5 | 4.3.1 |
| 3216759 | With the ip-acl-heavy TCAM profile, the following message might appear after you install an ACL with NCLU or cl-acltool and the ACL might not work correctlyhal_flx_acl_util.c:378 ERR hal_flx_acl_resource_release resource region 0 size 7387 create failed: No More ResourcesTo work around this issue, change the TCAM profile to acl-heavy or ip-acl-heavy with ACL non-atomic mode. | 3.7.15-4.4.4 | 4.4.5, 5.1.0-5.4.0 |
| 3209699 | RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) | 3.7.0-4.3.0, 4.4.0-5.2.1 | 4.3.1, 5.3.0-5.4.0 |
| 3192808 | When the switch receives an LLDP frame from a Cisco router right after a ptmd restart, the ptmd service crashes. | 4.3.0-5.2.1 | 5.3.0-5.4.0 |
| 3185796 | When you enable ACL nonatomic update mode in the /etc/cumulus/switchd.conf file, the switch starts dropping ICMPv6 neighbor advertisement packets, which leads to an outage because the attached hosts are unable to communicate with each other. | 4.3.0 | 4.3.1-4.4.5 |
| 3138746 | The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.4.0 |
| 3138137 | The OID 1.3.6.1.4.1.40310.4.3.1.1.5 doesn’t return all BGP unnumered interfaces. To workaround this issue, avoid multiple BGP sessions to routers using the same ID. If you have multiple peering sessions across subinterfaces that live in distinct VRFs, configure a separate router ID per VRF. If there are multiple peering sessions to the same device in the same VRF, consider consolidating into a single BGP session by either peering across a bond or by using a multi hop session between loopbacks. | 4.3.0 | 4.3.1-4.4.5 |
| 3136940 | The clagd process uses 100 percent CPU and eventually crashes with an Unable to allocate memory error. | 4.3.0 | 4.3.1-4.4.5 |
| 3135801 | Zebra rejects MAC IP updates from BGP when the MAC mobility sequence number that BGP sends is lower than the sequence number known to zebra When the MAC mobility sequence that BGP knows legitimately lowers (due to narrow timing conditions during convergence or after rebooting an MLAG pair one VTEP at a time), zebra rejects these updates and maintains a stale state. If the stale information that zebra uses points to the wrong VTEP address, traffic goes to the wrong VTEP and might drop. | 4.0.0-4.3.0, 4.4.0-4.4.5 | 3.7.16, 4.3.1 |
| 3131423 | During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. | 4.3.0-5.1.0 | 5.2.0-5.4.0 |
| 3129819 | On the EdgeCore AS4610 switch, the clagd service loses communication after 198 days of uptime. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3123556 | When you configure an interface in FRR to send IPv6 RAs before you configure the interface in the /etc/network/interfaces file, the switch does not process IPv6 RAs. To work around this issue, remove the interface configuration in FRR and reapply it. | 3.7.15-4.3.0, 4.4.0-5.1.0 | 4.3.1, 5.2.0-5.4.0 |
| 3119615 | In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.4.0 |
| 3117340 | When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service.

| 2556730 | CVE-2020-8625: A buffer overflow vulnerability was discovered in the SPNEGO implementation affecting the GSSAPI security policy negotiation in BIND, a DNS server implementation, which could result in denial of service (daemon crash), or potentially the execution of arbitrary code. Vulnerable: <= 9.11.5.P4+dfsg-5.1+deb10u2 Fixed: 9.11.5.P4+dfsg-5.1+deb10u3 | 4.0.0-4.3.1 | 4.4.0-4.4.5 |
| 2556691 | The following vulnerabilities have been announced in the openssl packages: CVE-2021-23840: Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. CVE-2021-23841: The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. CVE-2019-1551: There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Vulnerable: <= 1.1.1d-0+deb10u4 Fixed: 1.1.1d-0+deb10u5 | 4.0.0-4.3.0 | 4.3.1-4.4.5, 4.4.0-4.4.5 |

| 2556369 | If you use NCLU to configure an ACL for eth0, you can’t designate it as an INPUT rule; the rule is automatically created as a FORWARD rule in the /etc/cumulus/acl/policy.d/50_nclu_acl.rules file.To work around this issue, manually create an ACL in the /etc/cumulus/acl/policy.d/ file with “-A INPUT -i eth0”. | 4.2.1-4.4.5 | |
| 2556249 | On a Mellanox switch configured with the max acl-heavy or ip-acl-heavy profile, the cl-resource-query -j command takes a long time to run. | 4.3.0 | 4.3.1-4.4.5 |
| 2556082 | The NCLU net del vrf command does not delete a numbered VRF. For example:

| 2555873 | On Mellanox switches, egress ACLs with VLAN keys do not filter layer 2 multicast or broadcast traffic. | 4.3.0-4.4.5 | |
| 2555763 | The NCLU net del bgp neighbor command does not delete the neighbor and displays an error similar to the following:
To work around this issue, use the FRR command to delete a neighbor. | 4.3.0-4.4.5 | |
| 2555613 | The net show configuration commands command incorrectly displays the NCLU syntax to disable IPv6 forwarding on interfaces. For example:
The correct NCLU command to disable IPv6 forwarding is net add vlan 1 ipv6 forward off (without the hyphen). | 4.2.1-4.4.5 | |
| 2555318 | If you try to enable BGP graceful restart when it is already enabled, you see an error similar to the following in the frr.log file:
This error has no functional impact. | 4.3.0-4.4.5 | |
| 2554986 | The ethtool utility doesn’t contain the latest values, as a result the Revision Compliance field shows Unallocated. | 4.2.1-4.4.5 | |
| 2554812 | If the RMAC of a layer 3 SVI changes, the show vrf vni command is not updated with the new value. However, the new RMAC is seen in the show evpn vni command and is present on self-originated EVPN routes. | 4.2.1-4.4.5 | |
| 2554798 | On the Mellanox SN3700C switch, PIM multicast packets are duplicated at the egress VTEP. | 4.2.0-4.3.0 | 4.3.1-4.4.5, 4.4.0-4.4.5 |
| 2554783 | If you apply an outbound route map to a BGP peer that uses set as-path prepend last-as, advertised locally-originated routes have the ASN of the peer prepended to the AS path.This might trigger AS path loop prevention on the peer, where the peer ignores locally-originated prefixes. | 4.2.1-4.4.5 | 5.0.0-5.4.0 |
| 2554709 | The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. | 3.7.13-3.7.16, 4.2.1-4.4.5 | |
| 2554670 | When you have a large number of ACLs, the cl-acltool -L ip and cl-resource-query commands take a long time to complete. | 4.3.0-4.4.5 | |
| 2554582 | On switches with the Maverick ASIC, control traffic is dropped due to receive buffering. | 4.2.0-4.4.5 | |

| 2554261 | On Broadcom switches, when you create a VNI interface, switchd might crash with the following log message:switchd[6628]: log.c:72 CRIT backend/bcm/hal_bcm_vxlan.c:1285: | 4.3.0 | 4.3.1-4.4.5 |
| 2554222 | The NCLU command to enable bridge learning fails. As a work around, enable bridge learning in the /etc/network/interface file. For example:
| 4.2.1-4.4.5 | |
| 2554218 | MLAG packets received on the peer link are dropped instead of routed. | 4.2.0-4.4.5 | |
| 2554202 | The output of the net show commit command does not show the last commit or the specified commit number but is empty instead. | 4.2.1-4.4.5 | |
| 2553989 | Default policer configured for LACP as an INPUT chain rule in 00control_plane.rules is meant to protect CPU from an LACP storm. When LACP storm is originating out of a single bond or bond member interface in a switch with multiple bond interfaces, there is a possibility of other LACP bond interface(s) going down. | 4.2.1-4.4.5 | |
| 2553887 | When using TACACS+ configured with a DEFAULT user providing privilege level lower than 16, TACACS+ configured users with privilege level 16 access might not be able to run privilege level 16 NCLU commands, such as net add and net del and see an error similar to the following:
To work around this issue, remove the DEFAULT user from the TACACS+ server. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2553677 | When you configure an SNMPv3 user with the net-snmp-config configuration command from the libsnmp-dev package, you get an error message similar to the one below:
To work around this issue, use the NCLU command to configure SNMPv3 user parameters; for example:
Alternatively, directly edit the /etc/snmp/snmpd.conf file as described in the documentation. | 3.7.13-3.7.16, 4.0.0-4.4.5 | |
| 2553237 | The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. | 4.2.0-4.4.5 | |
| 2553116 | When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition. Avoid setting the interface speed or duplex mode directly with ethtool. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2553015 | If a neighbour contains a special character in PortID for LLDP, the net show interface command does not display the LLDP information or the command might fail. | 3.7.10-3.7.16, 4.2.0-4.4.5 | |
| 2552691 | On the EdgeCore AS4610 switch, the eth0 interface remains down when physically connected to a 1G interface. To work around this issue, configure the link speed to 1000 and set auto-negotiation on for the eth0 interface, then flap eth0 with the ip link set eth0 down/up command to bring up the port. | 4.2.0-4.4.5 | |
| 2552453 | On the Mellanox switch, RoCE with PFC configuration is not applied to all ports in hardware when a range is used in the traffic.conf file.To work around this issue, use NCLU to configure RoCE with PFC or list individual ports in the traffic.conf file. | 4.2.0-4.4.5 | |
| 2552309 | The following messages are seen on an Edgecord Minipack-AS8000 running Cumulus Linux 4.2.0:

| 2552266 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.7.14-3.7.16, 4.0.0-4.4.5 | |
| 2551666 | If you modify an interface name, then reuse the previous interface name for a different VLAN, the ifreload -a command generates an error similar to the following:
| 4.1.0-4.4.5 | |
| 2551578 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2551565 | If you toggle VRRP priority values between VRRP routers, then restart switchd, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affectedTo work around this issue, remove, then add back the VRRP configuration with NCLU or vtysh commands. | 3.7.13-3.7.16, 4.2.0-4.4.5 | |
| 2551335 | When TACACS+ is configured and the management VRF is enabled, users with privilege level 13 are prevented from running ip and cat commands. | 4.0.0-4.4.5 | |
| 2551305 | The net show configuration command provides the wrong net add command for ACL under the VLAN interface. | 3.7.12-3.7.16, 4.1.0-4.4.5 | |
| 2551273 | On a Mellanox SN2010 switch, the Locator LED is on after you upgrade Cumulus Linux. | 4.1.0-4.4.5 | |
| 2551221 | When span-to-cpu is enabled on L3 swp interface with an IP address configured, packets with destination IP as switchport’s IP address don’t reach switchport. To capture packets directed towards switcport’s IP, disable span-to-cpu and use tcpdump on swichport instead. | 4.2.0-4.4.5 | |
| 2551111 | If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. | 4.0.0-4.4.5 | |
| 2550974 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.16, 4.1.1-4.4.5 | |
| 2550793 | The NCLU net show bridge spanning-tree command displays the aging timer incorrectly. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550713 | Configuring the subinterface of a VXLAN uplink under another traditional bridge, which also has the VXLAN VNI enslaved, causes switchd to use high CPU due to very frequent VXLAN tunnel sync events.To work around this issue, do not enslave the subinterface of a VXLAN layer 3 uplink under a traditional bridge in a VXLAN configuration. | 4.1.1-4.4.5 | |
| 2550704 | On the Mellanox SN3420 switch, 25G SR optics only link up in force mode. | 4.3.0-4.3.1 | 4.4.0-4.4.5 |
| 2550642 | ACLs with SPAN target and in-interface as bond member are not supported on Spectrum-based switches | 4.2.0-4.4.5 | |
| 2550444 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550443 | The net show rollback description command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550243 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:
| 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2550056 | The ACCTON-DIAG option under the Cumulus Linux GRUB menu does not work. When you select this option, you see the following error:

| 3.7.12-3.7.16, 4.1.1-4.4.5 | |
| 2549392 | When you configure an RD or RT with NCLU, you see duplicate VNI stanzas in the /etc/frr/frr.conf file.To work around this issue, manually edit the etc/frr/frr.conf file to define advertise-all-vni before the RD or RT configuration within the l2vpn EVPN address family, then reload the FRR service with the sudo systemctl reload frr command. | 4.1.0-4.4.5 | |
| 2549371 | When Optimized Multicast Flooding (OMF) is enabled with the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/switchd.conf file, the switch continues to flood IPv6 multicast traffic to all slave ports when there is no MLD join receive. | 3.7.11-4.3.1 | 4.4.0-4.4.5 |
| 2548924 | On the EdgeCore Minipack AS8000, storm control does not restrict unknown unicast, broadcast, or multicast traffic. | 4.1.1-4.4.5 | |
| 2548657 | When you upgrade Cumulus Linux on the EdgeCore AS7726-32X or AS7326-56X switch, you might see firmware errors similar to the following:
You can safely ignore these error messages. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2548579 | The following security vulnerability has been announced: CVE-2020-10531: An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp. | 3.7.12, 4.0.0-4.4.5 | 3.7.13-3.7.16 |
| 2548315 | The following security advisory has been announced for bash: CVE-2019-18276 Qualys scan QID 372268 setuid vulnerability When bash or bash scripts are run setuid, bash is supposed to drop privileges, but does so incorrectly, so that an attacker with command access to the shell can use enable -f for runtime loading of a new builtin that calls setuid() to regain dropped privileges.To work around this issue, do not make bash or bash scripts setuid. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |

| 2548044 | When a remote VTEP withdraws a type-3 EVPN route, Cumulus Linux purges all MAC address and neighbor entries installed in the corresponding layer 2 VNI through that remote VTEP from the local EVPN and kernel forwarding tables. This purge occurs even if the remote VTEP does not withdraw type-2 routes carrying the MAC address or neighbor entries. The entries stay missing from the local EVPN and kernel forwarding tables until BGP updates the MAC address and neighbor. | 3.7.12-3.7.15, 4.0.0-4.4.5 | 3.7.16 |

| 2546991 | The FRR service does not provide a way for automation to know if the configuration applied properly. To work around this issue, execute the vtysh -f command in the automation file before starting the FRR service to validate the functional configuration and return an error code. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546895 | If you have configured a higher number of ports and VLANs (ports x VLANs) or the switch is a lower-powered (CPU) platform, the switchd service might fail to send a systemd keepalive within the watchdog timeout value (2 minutes by default) and you see an error similar to the following:bq. systemd[1]: switchd.service watchdog timeout (limit 2min)!To workaround this issue, either reduce the number of configured interfaces and, or VLANs, or increase the systemd timeout for switchd.serviceTo increase the systemd timeout:1.Edit the /etc/systemd/system/switchd.service.d/override.conf file and increase the WatchdogSec parameter2.Restart the switchd service with the sudo systemctl restart switchd.service commandsystemd attempts to restart the switchd service automatically (after the watchdog timeout).

| 2546225 | When you execute the following command on the Delta AG6248C switch, the switch reboots and then comes right back into Cumulus Linux without installing the new image. The install image is still in /var/lib/cumulus/installer, which causes issues with cl-support.
To work around this issue, use the onie-select command to access ONIE, and then use the nos-install command in ONIE to install a new binary image. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |
| 2546131 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |

| 2544113 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2543937 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |

| 2543401 | On the Mellanox Spectrum-2 switch, the time required to establish a link (from the time a link is set to admin up until the link becomes operationally up) can take up to 15 seconds on 40G interfaces and up to 30 seconds on 100G interfaces.To work around this issue, wait up to 15 seconds on 40G interfaces and 30 seconds on 100G interfaces for the link to establish. | 4.0.0-4.4.5 | |
| 2543211 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2543164 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2543096 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542945 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:
| 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542837 | On Mellanox switches, policer iptables are not working as expected. For example, when using a policer with mode KB/MB/GB to rate-limit interfaces, the syntax is accepted but the data plane transfer speed is not affected by the rule. | 3.7.6-3.7.8, 4.0.0-4.4.5 | 3.7.9-3.7.16 |
| 2542305 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.16, 4.0.0-4.4.5 | |
| 2542301 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2541212 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2541029 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540753 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:
| 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540444 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540274 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.16, 4.0.0-4.4.5 | |
| 2540204 | When links come up after FRR is started, VRF connected routes do not get redistributed. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540192 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540155 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2540042 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
| 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto lines exist. | 3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2539994 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:
| 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539962 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2539670 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539124 | The net add interface command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538590 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2537699 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2537544 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.16, 4.0.0-4.4.5 | |
| 2536576 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 4.0.0-4.4.5 | |
| 2536384 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 4.0.0-4.4.5 | |
| 2536242 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 4.0.0-4.4.5 | |
| 2535209 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.7.5-3.7.10, 4.0.0-4.4.5 | 3.7.11-3.7.16 |
| 2534734 | Span rules matching the out-interface as a bond do not mirror packets. | 4.0.0-4.4.5 | |
| 2533691 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 4.0.0-4.4.5 | |
| 2533337 | When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. | 4.0.0-4.4.5 | |
| 2531273 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. | 4.0.0-4.4.5 |
Fixed Issues in 4.3.0
| Issue ID | Description | Affects |
|---|---|---|
| 2959067 | ECMP produces errors indicating No More Resources and switchd crashes even when ECMP utilization is low. | 3.7.14.2-4.2.1 |
| 2687332 | When you configure BGP aggregate-address summary-only and any component route within the summary updates, all component routes within the summary update in the RIB on the device advertising the summary. This condition might result in increased CPU usageTo workaround this issue, remove the aggregate-address summary-only configuration, add a static route to Null0 for the prefix, and configure an outbound route map to restrict anything more specific than the desired prefix from being advertised. For example: Before:address-family ipv4 unicastAfter: ip route 10.10.0.0/16 Null0This example assumes no other static routes are present. Otherwise, you might need to configure additional route maps to limit the static routes being redistributed. | 3.7.12-4.2.1 |
| 2556334 | On the Mellanox SN-4700 switch, when you use a 2x100G configuration, the links do not come up. | |
| 2556279 | CVE-2021-3156: A serious heap-based buffer overflow has been discovered in sudo that is exploitable by any local user. It has been given the name Baron Samedit by its discoverer. The bug can be leveraged to elevate privileges to root, even if the user is not listed in the sudoers file. User authentication is not required to exploit the bug. Vulnerable: <= 1.8.27-1+deb10u2 Fixed: 1.8.27-1+deb10u3 | 4.0.0-4.2.1 |
| 2556217 | The following vulnerability affects lldpd: CVE-2020-27827: A packet that contains multiple instances of certain TLVs will cause lldpd to continually allocate memory and leak the old memory. As an example, multiple instances of system name TLV will cause old values to be dropped by the decoding routine. Fixed: 1.0.4-0-cl4.3.0u2 | 3.7.14-3.7.14.2, 4.0.0-4.2.1 |
| 2556215 | When you run any of the vtysh show bgp ipv4 or show bgp ipv6 statistics commands, the bgpd service crashes. | 4.2.1 |
| 2556010 | On Broadcom switches, after repeated VLAN or VXLAN configuration changes, switchd memory might not free up appropriately, which can lead to a crash. | 3.7.14, 4.0.0-4.2.1 |
| 2555761 | The following vulnerabilities were announced in the p11-kit (libp11-kit0) packages: CVE-2020-29361: Multiple integer overflows have been discovered in the array allocations in the p11-kit library and the p11-kit list command, where overflow checks are missing before calling realloc or calloc. CVE-2020-29362: A heap-based buffer over-read has been discovered in the RPC protocol used by thep11-kit server/remote commands and the client library. When the remote entity supplies a byte array through a serialized PKCS#11 function call, the receiving entity may allow the reading of up to 4 bytes of memory past the heap allocation. CVE-2020-29363: A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library. When the remote entity supplies a serialized byte array in a CK_ATTRIBUTE, the receiving entity may not allocate sufficient length for the buffer to store the deserialized value. Vulnerable: 0.23.15-2 Fixed: 0.23.15-2_deb10u1 | 4.0.0-4.2.1 |
| 2555690 | The NET-SNMP-EXTEND-MIB, disabled in Cumulus Linux 4.2.1 and 3.7.14 to prevent security vulnerability CVE-2020-15862, is re-enabled read-only. | 3.7.14-3.7.14.2, 4.2.1 |
| 2555588 | You can’t delete a BGP community list created with NCLU. | 4.2.1 |
| 2555531 | QinQ (802.1Q) packets routed to a layer 3 subinterface are still double tagged with the VLAN of the subinterface and the original inner VLAN when they leave the subinterface. | 4.2.0-4.2.1 |
| 2555528 | In an EVPN Active/Active configuration, when one of the peers reboots and begins to refresh IP neighbor entries shared by the MLAG peer, some of these ARP messages might be dropped by the MLAG peer’s ARP policer. To work around this issue, increase the burst value of the ARP policers to 200 or higher. | 3.7.14-4.2.1 |
| 2555492 | On Broadcom switches, when WARN level switchd log messages are generated, switchd might crash resulting in a core file generated on the system. | 3.7.14 |
| 2555484 | ospf6d restarts when you run the NCLU net show ospf6 databse command or the vtysh show ipv6 ospf6 database command. | 4.2.0-4.2.1 |
| 2555428 | When you change the SVI vlan-id value in the /etc/network/interfaces file, then run ifreload -a, the 802.1Q ID for the SVI in the kernel does not change.This operation is not supported in the kernel without recreating the SVI. To apply the change, run ifdown, then ifup for the SVI to recreate the interface. | 3.7.13-3.7.15, 4.2.1 |
| 2555426 | Broadcom switches running Cumulus Linux do not support EVPN Multihoming. When a BGP update with EVPN multihoming attributes is received, switchd crashes.EVPN Multihoming is supported on Mellanox switches only. | 4.2.1 |
| 2555400 | On the Edgecore AS7312 switch, eth0 and swp use the same MAC address. | 3.7.14-3.7.14.2, 4.0.0-4.2.1 |
| 2555380 | When you start asic-monitor, you might see increasing memory usage. | 4.2.1 |
| 2555373 | CVE-2020-27350: Missing input validation in the ar/tar implementations of APT, the high level package manager, could cause out-of-bounds reads or infinite loops, resulting in denial of service when processing malformed deb files. CVE-2020-27351: Various memory and file descriptor leaks were discovered in the Python interface to the APT package management runtime library, which could result in denial of service. Vulnerable: apt <= 1.8.2.1, python-apt <= 1.8.4.1 Fixed: apt 1.8.2.2, python-apt 1.8.4.3 | 4.0.0-4.2.1 |
| 2555339 | The following vulnerability has been announced in OpenSSL: CVE-2020-1971: A flaw in the GENERAL_NAME_cmp() function could cause a NULL dereference when both GENERAL_NAMEs contain an EDIPARTYNAME, resulting in denial of service. More information can be found at https://www.openssl.org/news/secadv/20201208.txt . Vulnerable: <= 1.1.1d-0+deb10u3 Fixed: 1.1.1d-0+deb10u4 | 4.0.0-4.2.1 |
| 2555223 | An EVPN route map filter matching a VNI on egress on the originating router might not set a large-community correctly:
To work around this issue, remove the VNI match to allow the tag to be applied on egress. The VNI match works if applied at some other non-originating router either in the ingress or egress direction. | 4.2.1 |
| 2554990 | When running traditional mode bridges at scale (for example, when you have more than 200 bridges and a large number of MAC addresses), MLAG bonds flap intermittently from dual to single connected, then back to dual connected, which causes a layer 2 loop and STP state changes. To work around this issue, either shut down one side of the MLAG bond or prune out VLANS over the bond. | 3.7.13-3.7.14.2, 4.0.0-4.2.1 |
| 2554982 | CVE-2020-28196: MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit. Vulnerable: 1.17-3 Fixed: 1.17-3+deb10u1 | 4.0.0-4.2.1 |
| 2554866 | On the Mellanox SN3420 switch, 1000BaseT and 1000Base-SX/LX modules do not link up. | 4.2.1 |
| 2554834 | CVE-2020-25709, CVE-2020-25710: Two vulnerabilities in the certificate list syntax verification and in the handling of CSN normalization were discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. An unauthenticated remote attacker can take advantage of these flaws to cause a denial of service (slapd daemon crash) via specially crafted packets. Vulnerable: <= 2.4.47+dfsg-3+deb10u3 Fixed: 2.4.47+dfsg-3+deb10u4 | 4.0.0-4.2.1 |
| 2554809 | Some non-Mellanox ethernet modules do not link up on the Mellanox SN3420 switch with Cumulus PSID in the Hardware revision. To see if a Mellanox SN3420 switch has the Cumulus PSID, check the output of mlxfwmanager for MSN3420-CxxxC_Ax in the Part Number Field. A Mellanox SN3420 switch with MSN3420-CxxxO_Ax has an Onie PSID and is unaffected by this issue.To work around this issue, use Mellanox ethernet modules with the Mellanox SN3420 switch, | 4.2.1 |
| 2554785 | After you reboot a Broadcom switch, switchd might fail to restart and you see logs in switchd.log similar to the following:Nov 12 12:20:05.063876 leaf01 switchd[9867]:Nov 12 12:20:05.064310 leaf01 switchd[9867]: hal_bcm_console.c:294 0:system_init:Nov 12 12:20:05.064428 leaf01 switchd[9867]: hal_bcm_console.c:294 system_init: Misc init failed: Operation timed outNov 12 12:20:05.064464 leaf01 switchd[9867]:Nov 12 12:20:05.091995 leaf01 switchd[9867]: hal_bcm_console.c:294 LED: Loading 256 bytes into LED program memoryNov 12 12:20:05.092029 leaf01 switchd[9867]:Nov 12 12:20:05.099547 leaf01 switchd[9867]: hal_bcm_console.c:294 PORT: Error: bcm ports not initializedNov 12 12:20:05.099579 leaf01 switchd[9867]:Nov 12 12:20:05.099646 leaf01 switchd[9867]: hal_bcm_console.c:294 Error: file /var/lib/cumulus/rc.datapath_0: line 81 (error code -1): script terminatedNov 12 12:20:05.099667 leaf01 switchd[9867]:Nov 12 12:20:05.099775 leaf01 switchd[9867]: hal_bcm_console.c:294 Error: file /etc/bcm.d/rc.soc: line 70 (error code -1): script terminatedNov 12 12:20:05.099798 leaf01 switchd[9867]:Nov 12 12:20:05.099871 leaf01 switchd[9867]: hal_bcm_console.c:294 ERROR loading rc script on unit 0Nov 12 12:20:05.099892 leaf01 switchd[9867]:Nov 12 12:20:05.099943 leaf01 switchd[9867]: hal_bcm_console.c:299 CRIT loading of rc script failed, aborting!To work around this issue, configure Cumulus Linux to boot with the ntel_iommu=off kernel command option:1.

For example: GRUB_CMDLINE_LINUX=“cl_platform=cel_e1031 console=ttyS1,115200n8 intel_iommu=off"3. Run the update-grub command4. Reboot the switch. | 3.7.11-4.2.1 |
| 2554730 | In an EVPN multihoming configuration, reloading FRR causes brief traffic loss. | 4.2.1 |
| 2554720 | If switchd successfully signals clagd that it is going down, clagd stops responding to keepalive echo requests from the peer instead of sending a good bye to the peer over both the peerlink and the backup switch. Eventually, the keepalive timer expires and the secondary switch becomes the primary, and brings the bonds and VNIs back up. However, if switchd does not successfully signal it is going down, (in the event of a crash), the primary switch continues to respond to keepalives, and the bonds and VNIs are down on both peers. | 3.7.12-3.7.14.2, 4.0.0-4.2.1 |
| 2554711 | On the Mellanox SN3700C switch, running cl-support with a large number of ports configured can cause switchd to crash. | 4.2.1 |
| 2554707 | On the Dell S5048F-ON switch, optical transceivers do not come up and the modules are in reset mode. | 4.0.0-4.2.1 |
| 2554588 | If you try to reconfigure a DHCP server after you delete the switch configuration with the net del all command, the dhcpd service fails because a duplicate process is runningTo work around this issue, edit the /usr/lib/python2.7/dist-packages/nclu/plugins/dhcp.py file to change:DHCPD_PID="-pf {0}” to:DHCPD_PID="-pf {1}" | 3.7.13-4.2.1 |
| 2554503 | If the peer link does not trunk all VLANs on an MLAG bond, all FDB entries learned through that MLAG bond are not redirected over the peer link when the MLAG bond goes down. As a result, traffic destined to the MAC addresses that arrives on the MLAG peer with the downed MLAG port is dropped. To work around this issue, ensure that the peer link trunks all VLANs that exist on all MLAG bonds. | 4.2.0-4.2.1 |
| 2554401 | On the Mellanox SN4600C switch, the fan speed fluctuates when only one PSU is plugged in. To work around this issue, use both PSUs. | 4.2.1 |
| 2554369 | Certain Dell S4048-ON switches show an incorrect vendor name and hang when you issue the reboot command. | 3.7.12-4.2.1 |
| 2554333 | The INPUT chain POLICE target acts as ACCEPT instead of continue. | 4.2.1 |
| 2554292 | With traditional bridges, a race condition occurs when Cumulus Linux tries to derive MAC addresses. To work around this issue, use a static MAC address; specify a MAC address in the /etc/network/interfaces file under the bridge’s stanza. | 4.2.1 |
| 2554258 | Interfaces configured to get an IP address with DHCP try only three times to secure a DHCP lease (instead of retrying indefinitely). If unsuccessful after the third try, the switch stops trying. | 4.2.1 |
| 2554253 | After upgrading the Mellanox SN2410 switch, the FAN is set to full speed. | 4.2.1 |
| 2554246 | When you back up and restore a configuration using the conf-backup utility, the switch might hang when rebooted. | 4.1.1-4.2.1 |
| 2553952 | On Mellanox Spectrum based switches running 4.1.0 or higher, if FORWARD chain ACLs are configured on the system, a switch port breakout action applied with a reload of the switchd service may cause switchd to crash. | 4.2.0-4.2.1 |
| 2553747 | On switches with the Spectrum ASIC, the IPv6 default route might be present in the kernel but missing in hardware when IPv6 RAs are received on SVIs configured with ip-forward off. | 3.7.11-3.7.14.2, 4.2.1 |
| 2553742 | The next hop for static routes configured in a non-default VRF might be incorrectly flagged as inactive. Remove and reconfigure the static VRF route to recover from this condition. | 4.2.1 |
| 2553731 | A ping via a dual-connected bond fails, and the audio stream is not routed or encapsulated through the layer 3 VNI. | 3.7.12-3.7.13, 4.0.0-4.2.1 |
| 2553586 | Multicast traffic on a VPN is sent to remote VTEPs that are not part of the VPN and the remote VTEPs receive multicast traffic encapsulated in a VXLAN ID that doesn’t exist. To work around this issue, disable IGMP snooping on the switch. | 3.7.12-3.7.13, 4.0.0-4.2.1 |
| 2553568 | After a MAC address moves from one remote VTEP to another, the MAC address continues to point to the old VTEP IP address in hardware. | 4.1.1-4.2.1 |
| 2553529 | In an MLAG configuration with a layer 3 VNI, when you bounce the peer link, all layer 2 VNIs listed under the layer 3 VNI are duplicated. To work around this issue, restart FRR with the sudo systemctl restart frr.service command. | 3.7.10-3.7.13, 4.1.1-4.2.1 |
| 2553468 | Digital Optical Monitoring (DOM) Data is displayed incorrectly on SFP fiber modules inserted in the Fiberstore N8500-48B6C, Celestica Questone, and Celestica RedstoneV switches. | 4.2.0-4.2.1 |
| 2553449 | On the the Dell N3248-PXE switch, when you insert two PSUs at different times, the newly inserted PSU is detected as OK but the fan and temp sensors are ABSENT. To work around this issue, remove power to both PSUs at the same time, then reinsert power simultaneously. | 3.7.12-3.7.13, 4.2.1 |
| 2553349 | When you delete a layer 2 VNI and VLAN, the layer 3 VNI reports an incorrect layer 2 VNI number. To work around this issue, either restart FRR or delete the VNI interface first, then delete the VLAN/SVI. | 4.2.0-4.2.1 |
| 2553278 | Leaked routes are sometimes missing from the destination VRF after a reboot. | 4.2.0-4.2.1 |
| 2553228 | On the Dell N3248PXE switch, RJ45 fixed copper ports that auto-negotiate with a 100M or 10M neighbor incorrectly negotiate a half-duplex link that generates errors. Half duplex modes are not supported on this platform. | 3.7.12-3.7.13, 4.2.1 |
| 2553219 | You cannot configure SNMPv3 trap-destinations in non-default VRFs with an authentication username that contains fewer than eight characters. | 3.7.12-4.2.1 |
| 2553118 | The Dell 100G-LR4 (Innolight) transceiver cannot link up due to a power budget exceeded error on the Mellanox SN4600C switch. | 4.2.0-4.2.1 |
| 2552939 | RX_DRP on a bond interface increases without any data traffic while the slave port does not increase. | 3.7.12-4.2.1 |
| 2552880 | IPv6 TCP or UDP connections (sourcing from an ephemeral port in the range 34048 to 35071) are not forwarded if the switch has more than one layer 2 VNI defined. The traffic might be locally switched on the bridge and dropped. To work around this issue, disable ARP/ND suppression to remove the internal ACL rule that affects the ports. | 3.7.13, 4.2.1 |
| 2552869 | On the Dell N3048EP switch, the module information from SFP ports is not displayed in the l1-show command.To work around this issue, use the ethtool -m command. | 3.7.13-4.2.1 |
| 2552853 | Tenant VRF BGP peers appear in the EVPN RMAC and nexthop tables, which causes the kernel RMAC to point at invalid IP address. | 3.7.12-3.7.14.2, 4.0.0-4.2.1 |
| 2552744 | Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks CVE-2020-14351 CVE-2020-29660 CVE-2020-29661 CVE-2020-25704 CVE-2020-28974 CVE-2020-25705 CVE-2020-28915 CVE-2020-25211 CVE-2019-19338 CVE-2020-0305 CVE-2019-18885 CVE-2019-19072 CVE-2020-12652 CVE-2020-24394 CVE-2020-25641 CVE-2019-3874 CVE-2019-5489. (CVE-2020-27825 CVE-2020-29369 CVE-2020-29372 CVE-2020-29534 are not applicable to Cumulus Linux)For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 4.2.0-4.2.1 |
| 2552742 | On the Mellanox SN2410 switch, you see switchd core and GBIN_MALLOC errors.To work around this issue, restart switchd. | 3.7.12-4.2.1 |
| 2552710 | The MLAG bonds on a secondary switch do not change to a unique MAC address on the peerlink. As a result, a backup double failure can occur where both peers go down. | 4.2.0-4.2.1 |
| 2552704 | In a traditional bridge configuration with ip-forward off, neighbors are synchronized to hardware with a switchd restart but are cleared when you flap the bridge interface. | 3.7.10-3.7.14.2, 4.0.0-4.2.1 |
| 2552687 | When you boot Cumulus VX 4.2 for the first time, ZTP does not execute because it thinks that the /etc/shadow file has been modified. This is due to the default password change implemented in CL 4.2.To work around this issue, boot the switch, manually change the password, then run sudo ztp -R to reset the ZTP script. | 4.2.0-4.2.1 |
| 2552527 | Ingress SPAN/ERSPAN does not mirror packets when the next hop is EVPN encapsulated. | 3.7.7-3.7.13, 4.0.0-4.2.1 |
| 2552354 | On the Mellanox SN4700 switch, you might see Bad signal integrity issues on 200G and 400G ports. | 4.2.1 |
| 2551873 | If you have an existing community list of any type, redefining the same sequence number results in the entire community list being deleted. To work around this issue, delete the community list sequence before trying to adjust it. | 4.2.0-4.2.1 |
| 2551747 | In OVSDB high availability mode, deleting > 200 VLAN bindings might cause ovs-vtepd to crash. Limit the deletion to 200 or fewer VLAN bindings. | 3.7.12-3.7.13, 4.0.0-4.2.1 |
| 2551687 | When you run cl-ecmpcalc to determine a hardware hash result, tests might fail. | 4.2.0-4.2.1 |
| 2551422 | On Mellanox switches with the Spectrum-2 switch, the lpm-balanced forwarding profile does not work. | 4.1.1-4.2.1 |
| 2551187 | dot1qVlanIndex in the dot1qVlanStaticTable of the SNMP Q-BRIDGE-MIB does not use VLAN ID and does not comply with RFC 4363. | 4.1.1-4.2.1 |
| 2551124 | When the dynamic or static flag on a bridge fdb (MAC) entry is changed to the opposite state, the new flag is not set appropriately in hardware. This can allow a static fdb entry to be unexpectedly learned dynamically on a different interface, or can prevent a dynamic entry from being updated or learned elsewhere. This condition can occur during a manual replacement of a local MAC address or when EVPN updates a dynamic MAC address to add or remove the Sticky Mac flag. Either situation results in the MAC address keeping the original flag in hardware. To work around this issue, delete or withdraw the fdb entry, then add the static MAC address directly. For example:
If you are unable to delete an EVPN-learned remote MAC address, you can replace the dynamic MAC address with a local static one, then delete the static MAC address. For example:
| 4.0.0-4.2.1 |
| 2550973 | After you enable ROCE with the net add interface command, you cannot verify the command because it is not shown in the net show config command output. | 4.1.1-4.2.1 |
| 2550906 | After you delete a bond, the deleted bond members have the deleted bond MAC address instead of their original MAC address, which might result in traffic being discarded. To work around this issue, perform a full switch restart. | 4.1.1-4.2.1 |
| 2550796 | On a Broadcom switch with the Trident2+ ASIC, ACL rules for VLANs are not applied after a reboot and the counters remain at zero. To work around this issue, either do not set acl.non_atomic_update_mode = TRUE in the /etc/cumulus/switchd.conf file or run the cl-acltool -i command after the reboot to install the ACLs. | 3.7.12-4.2.1 |
| 2550478 | VXLAN interface as in-interface or out-interface in an ACL is not supported in Spectrum-based switches. | 3.7.7-4.2.0 |
| 2550374 | CPU utilization may increase when clag-managed bond interfaces are operationally/LACP down but the physical carrier remains up on the bond member switchports. This condition occurs when clag bond redirection is enabled and bond members remain up while the parent bond does not negotiate LACP. This issue is resolved in Cumulus Linux 3.7.14. | 3.7.9-3.7.13, 4.0.0-4.2.1 |
| 2550348 | Due to a known limitation, DHCPv6 snooping is not supported on Mellanox platforms. Please refer the Mellanox support case | 4.2.0-4.2.1 |
| 2550276 | In LLDP, the snmp subagent loses all subsequent lldpRemSysName (1.0.8802.1.1.2.1.4.1.1.9) entries after an entry with a missing SysName is added.All the information from lldpctl is correct. Only the entries after the entry that is missing a SysName in lldpRemSysName disappear from the snmp subagent. | 3.7.12-4.2.1 |
| 2549838 | In vtysh, if you configure, then remove a layer 3 VNI for a VRF, the VNI is removed from zebra even if the VNI interface still exists in the kernel. If you configure a layer 2 VNI as a layer 3 VNI by mistake, removing the layer 3 VNI binding removes it from zebra but EVPN-learned MACs and neighbors are not installed into the kernel. To work around this issue, delete, then re-add the missing VNI. For example:
If you flap the link with the ip link set vni10100 down; ip link set vni10100 up commands, zebra does not re-add the VNI. | 3.7.12-4.2.1 |
| 2549784 | On Mellanox switches, when the networking service and switchd starts up, a rare condition might occur where switchd crashes and the following log message is generated:
| 4.1.0-4.2.1 |
| 2549225 | You might see the following gport error messages in switchd.log:

| 2548930 | On Mellanox Spectrum switches that contain an OSPF IP unnumbered neighborship with a high scale of prefixes being learned, a link flap might cause the neighbor entry to not be programmed in hardware. | 3.7.11-4.2.1 |
| 2548672 | When a multipath route that contains an EVPN path exists together with an IPv4 BGP path in the VRF, the RMAC to VTEP binding is incorrect. This invalid entry occurs because Cumulus Linux treats IPv4 routes received over the eBGP IPv4 peering incorrectly in the VRF. To work around this issue, remove the unnecessary eBGP IPv4 peering. | 3.7.12-3.7.15, 4.0.0-4.2.1 |
| 2548485 | If you configure the aggregate-addresssummary-only option before injecting a component of the same aggregate into the BGP table with the network or redistribute command, when you remove the aggregate-address configuration, the component stays suppressed; it is not advertised to peers. For example:Existing configuration:router bgp 1If you add network 50.0.0.1/32, you see the following (expected) BGP table entries:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath,Removing aggregate-address 50.0.0.0/8 summary-only at this point results in the following (unexpected) BGP table entry:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath,To work around this issue, remove, then re-add the component prefix routes. | 3.7.12-4.2.1 |

| 2547068 | Hardware platforms using the Intel D-1500 CPU series might reboot unexpectedly To work around this issue, contact your hardware vendor to inquire if a new version of BIOS with a microcode fix is available or manually disable CPU C-states in the kernel as outlined below To permanently disable C-states using a kernel boot parameter:1. Edit /etc/default/grub to add the argument processor.max_cstate=0 to the variable GRUB_CMDLINE_LINUX. For example, if /etc/default/grub file contains the line GRUB_CMDLINE_LINUX=“cl_platform=accton_as7726_32x console=tty0 console=ttyS0,115200n8 intel_iommu=off pcie_aspm=off”, change it to GRUB_CMDLINE_LINUX=“cl_platform=accton_as7726_32x console=tty0 console=ttyS0,115200n8 intel_iommu=off pcie_aspm=off processor.max_cstate=0”2. Run sudo update-grub3. Reboot the system with sudo rebootTo disable cstates in realtime on the current system, which does not persist through a reboot:1. Confirm that the libpci3 package is installed. Run dpkg-query -l libpci3 and confirm the following line is displayed:ii libpci3:amd64 1:3.2.1-3 amd64 Linux PCI Utilities (shared library)The first field above should read ii. If not, install the libpci3 package by running sudo apt upgrade;sudo apt install libpci32. Disable C-states by running the command ./cpupower idle-set -d 2C-states are disabled by default in Cumulus Linux 4.3.0 and later. | 3.7.9-4.2.1 |
