Open Issues in 3.7.16
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3418046 None | 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 | 5.5.0-5.6.0 |
| 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. | 3.7.0-3.7.16, 4.3.1-4.4.5 | |
| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |
| 3216922 None | 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 | 5.3.0-5.6.0 |
| 3216921 None | 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 None | 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 | |
| 3209699 None | 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, 5.3.0-5.6.0 |
| 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, 5.2.0-5.6.0 |
| 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 | 5.2.0-5.6.0 |
| 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, 5.2.0-5.6.0 |
| 3077737 | 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 | 4.3.1-4.4.5, 4.4.4-4.4.5 |
| 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 | |
| 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 | 4.3.1-4.4.5 |
| 3021693 | 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 | 4.3.1, 4.4.4-4.4.5, 5.2.0-5.6.0 |
| 3017190 | When you power cycle the switch, multiple interfaces came up in a PoE disabled state To work around this issue, run the sudo poectl -a | grep disabled command to find ports with disabled POE. Run the sudo poectl -e swp1-swp48 command to enable POE on affected ports. | 3.7.10-3.7.16 | |
| 3015881 | Traffic flows fail because the remote VTEP IP address is missing in the layer 3 neighbor table in hardware on the switch. This happens when there is a neighbor entry for the same /32 that we have also received a type-5 route for. When the route is learned after the neighbor entry there is a timing condition that can be hit that will cause the neighbor entry to get removed from hardware when the route is installed in hardware This condition has been seen when customers re-use the VTEP IP on an interface inside of a vrf. The neigh entry for the TEP IP is installed when a symmetric route is learned via that VTEP. The Type-5 route for the TEP IP is learned in the VRF if the customer has redistributed it or advertised it within BGP in the VRF. | 3.7.15-3.7.16 | |
| 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 | 5.1.0-5.6.0, 5.2.0-5.6.0 |
| 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 | 4.3.1-4.4.5 |
| 2972538 | With RADIUS enabled for user shell authentication, there might be a delay in local user authentication for non cumulus user accounts. | 3.7.15-3.7.16 | |
| 2965759 | On the EdgeCore AS4610-54T switch, the fan speed reports a minimum threshold in the logs. | 3.7.15-3.7.16 | |
| 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, 5.1.0-5.6.0 |
| 2959067 | ECMP produces errors indicating No More Resources and switchd crashes even when ECMP utilization is low. | 3.7.14.2-4.2.1 | 4.3.0-4.4.5 |
| 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, 5.0.0-5.6.0 | |
| 2947679 | If the clagd service stops during initDelay, the peerlink flag does not clear from any VNIs that become dual connected during this time. switchd uses the peerlink flag to program MLAG loop prevention. As a result of the overlapping stale flags, traffic destined for the VXLAN might drop. | 3.7.15-3.7.16 | |
| 2934939 | 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. | 3.7.12-3.7.16 | |
| 2899422 | Broadcom switches return a table full error when creating VXLAN gports, which causes {switchd to crash. | 3.7.15-4.3.0 | 4.3.1-4.4.5 |
| 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 | 4.3.1-4.4.5, 5.1.0-5.6.0 |
| 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 | 4.3.1-4.4.5 |
| 2866084 | When you reboot a VTEP, MAC address entries might become out of sync between the kernel FDB table and the EVPN MAC VNI table on remote VTEPs. The impacted MAC entries are installed against the rebooted VTEP IP address in the kernel FDB and the correct VTEP IP is present in the EVPN MAC VNI table. To work around this issue, clear all corrupted MAC address entries in the kernel FDB with the bridge fdb deldev command, then add “vxlan-learning”: “off” in the /etc/network/ifupdown2/policy.d/vxlan.json file:$ cat /etc/network/ifupdown2/policy.d/vxlan.jsonReboot the affected switches. | 3.7.12-4.3.0 | 4.3.1-4.4.5 |
| 2859177 | The cl-route-check –layer3 command fails with a memory error. For example:cumulus@switch:~$ sudo cl-route-check –layer3Traceback (most recent call last): | 3.7.15-3.7.16 | |
| 2853536 | MLAG between Cumulus Linux and Arista devices might result in some links being suspended by the Arista devices with the error LACP partner validation failedThis happens when you use the same LACP port ID for more than one bond member on the Cumulus Linux switch To work around this issue, run the net add bond command on the bond on the Cumulus Linux switch. For proper operation, you need to make the equivalent change on the device on the other side of the link. | 3.7.15-3.7.16 | |
| 2827336 | After bringing up a bridge port, there is a multi second delay before the bridge port is able to learn any MAC addresses or neighbors, which causes a forwarding delay (about six seconds with 300 or more VLANs). | 3.7.15-3.7.16 | |
| 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 | 5.0.0-5.6.0 |
| 2798979 | Configuring a route map to filter VNIs will cause type-3 routes not to be advertised even for L2VNIs permitted through the route map | 3.7.15-3.7.16 | |
| 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 | 4.3.1 |
| 2754791 | Remote MAC addreses in zebra are out of sync with bgpd. The zebra MAC addresses point to an incorrect (old) VTEP IP address and the sequence number is one higher than in BGP. | 3.7.14.2-3.7.16, 4.3.0-4.4.5 | |
| 2743186 | When you use MD5 passwords and you configure a non-default VRF before the default VRF in the /etc/frr/frr.conf file, numbered BGP sessions do not establish. | 3.7.15-5.1.0 | 5.2.0-5.6.0 |
| 2734107 | When withdrawal and advertisement processing occurs in short succession, type-2 routes with an IP are not imported into layer 2 VNIs. | 3.7.12-4.3.0, 4.4.0-4.4.1 | 4.3.1, 4.4.2-4.4.5 |
| 2728207 | CVE-2021-3570: A flaw was found in the ptp4l program of the linuxptp package. A missing length check when forwarding a PTP message between ports allows a remote attacker to cause an information leak, crash, or potentially remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |

| 2684452 | When a VTEP is rebooted, MAC address entries might become out of sync between the kernel fdb table and the EVPN MAC VNI table on remote VTEPs. The impacted MAC entries will be installed against the rebooted VTEP IP in the kernel fdb and the correct VTEP IP will be present in the EVPN MAC VNI table You can work around this issue with the following steps:1. Clear all corrupted mac entries in the kernel FDB with the bridge fdb deldev command2. Add “vxlan-learning”: “off” under /etc/network/ifupdown2/policy.d/vxlan.json$ cat /etc/network/ifupdown2/policy.d/vxlan.json3. Reboot the affected switch(es) | 3.7.12-3.7.16 | |
| 2669858 CM-32169 | OpenSSH is vulnerable to CVE-2020-14145, as described in https://www.fzi.de/fileadmin/user_upload/2020-06-26-FSA-2020-2.pdf. This is an information leak in algorithm negotiation that can allow man-in-the-middle attacks on initial connection attempts without a previously stored server host key on the client. If desired, mitigation using UpdateHostKeys and HostKeyAlgorithms is also given in that paper. | 3.7.14-3.7.16, 4.0.0-4.4.5 | |
| 2656291 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

| 2653400 None | 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. | 3.7.10-3.7.16 | |
| 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 | 4.3.1-4.4.5 |
| 2648658 | If you try to use more than one percent of max-ecmp-nexthops, you get an error indicating a failure. | 3.7.15-4.3.1 | 4.4.0-4.4.5 |
| 2638137 | When you delete a static route using NCLU, the configuration is not deleted from the running configuration or from the /etc/frr/frr.conf file. | 3.7.13-3.7.16 | |
| 2633245 | On the Dell N3048EP-ON switch, the SPF+ ports remain down after a power cycle. | 3.7.10-3.7.16 | |
| 2607965 | On the EdgeCore AS7726 switch, when you run the NCLU net show system command, you see the error Command not found. | 3.7.14.2-3.7.16 | |
| 2562347 | When you bring VXLAN interfaces up and down physically or administratively, the MTU for the SVIs changes to 1550 (the default value). | 3.7.14.2-3.7.16 | |
| 2556037 CM-33012 | After you add an interface to the bridge, an OSPF session flap might occur | 3.7.9-4.2.0 | 4.2.1-4.4.5 |
| 2555908 CM-32940 | If the you add the MLAG backup IP address to the MLAG peer in the secondary role while the peer link is down, the LACP sys-mac does not use the MLAG system MAC address (clagd-sys-mac) when the peer link comes back up To work around this issue, wait until the peer link is up to add the MLAG backup IP address. To recover from this condition, restart clagd with the sudo systemctl restart clagd command. | 3.7.12-4.0.1 | 4.1.0-4.4.5 |
| 2555528 CM-32750 | 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 | 4.3.0-4.4.5 |
| 2555175 CM-32528 | Control Plane Traffic (example - BGP peering from Leaf to Spine) goes down on Leaf due to Hold Down Timer Expiration of peer following prolonged link flaps on downlinks when vxlan enabled vlans are carried on the flapping link. | 3.7.15-3.7.16, 4.2.1-4.4.5 | |
| 2554785 CM-32275 | 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. Open the /etc/default/grub file with a text editor2. Edit the GRUB_CMDLINE_LINUX variable by adding the string intel_iommu=off at the end. 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 | 4.3.0-4.4.5 |
| 2554709 CM-32217 | 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 | |
| 2554588 CM-32149 | 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 | 4.3.0-4.4.5 |
| 2554369 CM-32006 | Certain Dell S4048-ON switches show an incorrect vendor name and hang when you issue the reboot command. | 3.7.12-4.2.1 | 4.3.0-4.4.5 |
| 2553887 CM-31700 | 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 CM-31605 | 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:

| 2552266 CM-30863 | 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 | |

| 2546203 CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior: * Both the inner and outer VLAN information is sent as part of VLAN TLVs in the LLDP packet. * If the outer VLAN ID is the same as the inner VLAN ID, only one VLAN TLV is sent with that VLAN ID in the LLDP packet. | 3.7.11-3.7.16 | |
| 2546131 CM-27581 | 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 | |

| 2543211 CM-25890 | 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 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2542979 CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-4.1.1 | 4.2.0-4.4.5 |
| 2542945 CM-25740 | 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 | |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |
| 2540885 CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.16 | |
| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | 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 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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 | |
| 2538256 CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.7.2-4.0.1 | 4.1.0-4.4.5 |
| 2537820 CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2537699 CM-23075 | 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 CM-23021 | 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 | |
| 2537378 CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.7.1-3.7.16 | |
| 2537188 CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.16 | |
| 2537104 CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.7.1-3.7.16 | 4.0.0-4.4.5 |
| 2537061 CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.7.1-4.0.1 | 4.1.0-4.4.5 |
| 2536608 CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.7.0-3.7.16 | |
| 2536384 CM-22386 | 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 | |
| 2536179 CM-22228 | 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 CM-22041 | 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 CM-22020 | 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 | |

| 2699464 | In a VXLAN fabric with ToR switches configured in a MLAG pair, BUM traffic received on a VXLAN tunnel is decapsulated and forwarded on the peer link bond. The BUM traffic is then encapsulated by the peer switch and sent back to the fabric. The issue has been seen in environments where the following conditions exist at the same time:1) high VNI scale2) switchd is busy processing updates3) clagd is in a transition state, such as Up, then Down, then Up. For example, when clagd restarts, the switch reboots, and so onThe problem is seen on the switch that experiences the clagd state transition. | 3.7.12-3.7.15 |

3.7.15 Release Notes
Open Issues in 3.7.15
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3418046 None | 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 | 5.5.0-5.6.0 |
| 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. | 3.7.0-3.7.16, 4.3.1-4.4.5 | |
| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |
| 3216922 None | 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 | 5.3.0-5.6.0 |
| 3216921 None | 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.

| 3209699 None | 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, 5.3.0-5.6.0 |
| 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, 5.2.0-5.6.0 |
| 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 | 5.2.0-5.6.0 |
| 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 | |
| 3077737 | 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 | 4.3.1-4.4.5, 4.4.4-4.4.5 |
| 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 | |
| 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 | 4.3.1-4.4.5 |
| 3021693 | 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 | 4.3.1, 4.4.4-4.4.5, 5.2.0-5.6.0 |
| 3017190 | When you power cycle the switch, multiple interfaces came up in a PoE disabled state To work around this issue, run the sudo poectl -a | grep disabled command to find ports with disabled POE. Run the sudo poectl -e swp1-swp48 command to enable POE on affected ports. | 3.7.10-3.7.16 | |
| 3015881 | Traffic flows fail because the remote VTEP IP address is missing in the layer 3 neighbor table in hardware on the switch. This happens when there is a neighbor entry for the same /32 that we have also received a type-5 route for. When the route is learned after the neighbor entry there is a timing condition that can be hit that will cause the neighbor entry to get removed from hardware when the route is installed in hardware This condition has been seen when customers re-use the VTEP IP on an interface inside of a vrf. The neigh entry for the TEP IP is installed when a symmetric route is learned via that VTEP. The Type-5 route for the TEP IP is learned in the VRF if the customer has redistributed it or advertised it within BGP in the VRF. | 3.7.15-3.7.16 | |
| 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 | 5.1.0-5.6.0, 5.2.0-5.6.0 |
| 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 | 4.3.1-4.4.5 |
| 2973714 | 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 | 3.7.16, 4.3.1, 4.4.2-4.4.5, 5.0.0-5.6.0 |
| 2972538 | With RADIUS enabled for user shell authentication, there might be a delay in local user authentication for non cumulus user accounts. | 3.7.15-3.7.16 | |
| 2965759 | On the EdgeCore AS4610-54T switch, the fan speed reports a minimum threshold in the logs. | 3.7.15-3.7.16 | |
| 2964279 | When a VNI flaps, an incorrect list of layer 2 VNIs are associated with a layer 3 VNI. The NCLU net show evpn vni detail command output shows duplicate layer 2 VNIs under a layer 3 VNI. | 3.7.15, 4.4.2-4.4.5, 5.0.0-5.6.0 | 3.7.16 |

| 2947679 | If the clagd service stops during initDelay, the peerlink flag does not clear from any VNIs that become dual connected during this time. switchd uses the peerlink flag to program MLAG loop prevention. As a result of the overlapping stale flags, traffic destined for the VXLAN might drop. | 3.7.15-3.7.16 | |
| 2943442 | 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. | 3.7.15-4.3.0, 4.4.2-5.0.1 | 4.3.1, 5.1.0-5.6.0 |
| 2941560 | CVE-2021-45944 CVE-2021-45949: Multiple security issues were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which could result in denial of service and potentially the execution of arbitrary code if malformed document files are processed Vulnerable: <= 9.26a~dfsg-0+deb8u7Fixed: 9.26a~dfsg-0+deb8u | 3.7.0-3.7.15 | 3.7.16 |

| 2934940 CM-32683 | 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 | 3.7.16, 4.3.0-4.4.5 |
| 2934939 | 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.

| 2552266 CM-30863 | 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 | |

For the detailed security status of sudo please refer to its security tracker page at: https://security-tracker.debian.org/tracker/sudoVulnerable versions: < 1.8.27-1+deb10u1Fixed versions: >= 1.8.27-1+deb10u1To work around this iisue, disable (comment out) any sudoers entries in /etc/sudoers or files in /etc/sudoers.d that have entries with !root in them. Only root or other users with a uid of 0 that are affected. | 3.7.9-3.7.16 | 4.0.0-4.4.5 |
| 2544556 CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:
If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-4.1.1 | 4.2.0-4.4.5 |
| 2544463 CM-26599 | 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 CM-26595 | 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 CM-26516 | 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 | |
| 2544235 CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.16 | |
| 2544155 CM-26423 | 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 CM-26412 | 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 | |
| 2543900 CM-26288 | 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 CM-26256 | 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 | |
| 2543840 CM-26255 | On the Mellanox SN2700 switch, you cannot enable resilient hashing (RASH) and set the bucket size to 64 in the traffic.conf file. | 3.7.6-3.7.16 | |
| 2543800 CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.16 | 4.0.0-4.4.5 |
| 2543647 CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:
| 3.7.6-4.2.1 | 4.3.0-4.4.5 |
| 2543646 CM-26136 | 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 | |
| 2543627 CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543270 CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-4.1.1 | 4.2.0-4.4.5 |
| 2543211 CM-25890 | 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 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2542979 CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-4.1.1 | 4.2.0-4.4.5 |
| 2542945 CM-25740 | 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 | |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |
| 2540885 CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.16 | |
| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | 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 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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 | |
| 2538256 CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.7.2-4.0.1 | 4.1.0-4.4.5 |
| 2537820 CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2537699 CM-23075 | 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 CM-23021 | 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 | |
| 2537378 CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.7.1-3.7.16 | |
| 2537188 CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.16 | |
| 2537104 CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.7.1-3.7.16 | 4.0.0-4.4.5 |
| 2537061 CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.7.1-4.0.1 | 4.1.0-4.4.5 |
| 2536608 CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.7.0-3.7.16 | |
| 2536384 CM-22386 | 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 | |
| 2536179 CM-22228 | 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 CM-22041 | 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 CM-22020 | 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 | |
| 2533691 CM-19788 | 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 | |
| 2532017 CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-4.0.1 | 4.1.0-4.4.5 |

| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3418046 None | 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 | 5.5.0-5.6.0 |
| 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. | 3.7.0-3.7.16, 4.3.1-4.4.5 | |
| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |

| 2934939 | 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. | 3.7.12-3.7.16 | |

| 2552266 CM-30863 | 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 | |

| 2546225 CM-27627 | 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 | |
| 2546203 CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior: * Both the inner and outer VLAN information is sent as part of VLAN TLVs in the LLDP packet. * If the outer VLAN ID is the same as the inner VLAN ID, only one VLAN TLV is sent with that VLAN ID in the LLDP packet. | 3.7.11-3.7.16 | |
| 2546131 CM-27581 | 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 | |
| 2546010 CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.16 | |
| 2545997 CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.16 | |

To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.16, 4.0.0-4.4.5 | |
| 2544953 CM-26905 | When you update the hostname of a switch with the NCLU net add hostname command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.16, 4.0.0-4.4.5 | |
| 2544904 CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-4.1.1 | 4.2.0-4.4.5 |
| 2544829 CM-26829 | Frames received with a VLAN tag of 0 on an interface configured as a bridge port and forwarded to the CPU for processing might appear tagged with the native VLAN when viewed with tcpdump. | 3.7.8-3.7.16 | |
| 2544671 CM-26736 | Package : sudoCVE ID : CVE-2019-14287Debian Bug : 942322Joe Vennix discovered that sudo, a program designed to provide limited super user privileges to specific users, when configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification, allows to run commands as root by specifying the user ID -1 or 4294967295. This could allow a user with sufficient sudo privileges to run commands as root even if the Runas specification explicitly disallows root access Details can be found in the upstream advisory at https://www.sudo.ws/alerts/minus_1_uid.html We recommend that you upgrade your sudo packages.

| 2543800 CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.16 | 4.0.0-4.4.5 |
| 2543647 CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:
| 3.7.6-4.2.1 | 4.3.0-4.4.5 |
| 2543646 CM-26136 | 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 | |
| 2543627 CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543270 CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-4.1.1 | 4.2.0-4.4.5 |
| 2543211 CM-25890 | 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 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2542979 CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-4.1.1 | 4.2.0-4.4.5 |
| 2542945 CM-25740 | 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 | |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |
| 2540885 CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.16 | |
| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | 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 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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 | |
| 2538256 CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.7.2-4.0.1 | 4.1.0-4.4.5 |
| 2537820 CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2537699 CM-23075 | 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 CM-23021 | 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 | |
| 2537378 CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.7.1-3.7.16 | |
| 2537188 CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.16 | |
| 2537104 CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.7.1-3.7.16 | 4.0.0-4.4.5 |
| 2537061 CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.7.1-4.0.1 | 4.1.0-4.4.5 |
| 2536608 CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.7.0-3.7.16 | |
| 2536384 CM-22386 | 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 | |
| 2536179 CM-22228 | 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 CM-22041 | 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 CM-22020 | 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 | |
| 2533691 CM-19788 | 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 | |
| 2532017 CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-4.0.1 | 4.1.0-4.4.5 |

| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |

| 2934939 | 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. | 3.7.12-3.7.16 | |

| 2885238 | The following vulnerabilities have been announced in bluez, the Linux Bluetooth protocol stack:CVE-2019-8921: SDP infoleak; the vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation of BlueZ. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data CVE-2019-8922: SDP Heap Overflow; this vulnerability lies in the SDP protocol handling of attribute requests as well. By requesting a huge number of attributes at the same time, an attacker can overflow the static buffer provided to hold the response CVE-2021-41229: sdp_cstate_alloc_buf allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash Vulnerable: <= 5.43-2+deb9u2~deb8u3Fixed: 5.43-2+deb9u2~deb8u4 | 3.7.0-3.7.15 | 3.7.16 |

| 2552266 CM-30863 | 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 | |

| 2547068 CM-28046 | 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 | 4.3.0-4.4.5 |
| 2546991 CM-28003 | The FRR service does not provide a way for automation to know if the configuration applied properly.

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 | |
| 2546203 CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior: * Both the inner and outer VLAN information is sent as part of VLAN TLVs in the LLDP packet. * If the outer VLAN ID is the same as the inner VLAN ID, only one VLAN TLV is sent with that VLAN ID in the LLDP packet. | 3.7.11-3.7.16 | |
| 2546131 CM-27581 | 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 | |

| 3.7.6-4.2.1 | 4.3.0-4.4.5 |
| 2543646 CM-26136 | 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 | |
| 2543627 CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543270 CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-4.1.1 | 4.2.0-4.4.5 |
| 2543211 CM-25890 | 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 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |

| 2542945 CM-25740 | 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 | |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |
| 2540885 CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.16 | |
| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:

| 2540444 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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 | |
| 2538256 CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.7.2-4.0.1 | 4.1.0-4.4.5 |
| 2537820 CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2537699 CM-23075 | 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 CM-23021 | 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 | |
| 2537378 CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.7.1-3.7.16 | |
| 2537188 CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.16 | |
| 2537104 CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.7.1-3.7.16 | 4.0.0-4.4.5 |
| 2537061 CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.7.1-4.0.1 | 4.1.0-4.4.5 |
| 2536608 CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.7.0-3.7.16 | |
| 2536384 CM-22386 | 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 | |
| 2536179 CM-22228 | 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 CM-22041 | 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 CM-22020 | 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 | |
| 2533691 CM-19788 | 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 | |
| 2532017 CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-4.0.1 | 4.1.0-4.4.5 |
Fixed Issues in 3.7.14

| 2556019 CM-32997 | After you add an interface to a bridge using the NCLU net add bridge bridge ports command, the bridge can go down and its MAC address changesTo work around this issue, use Linux commands to add an interface to a bridge. | 3.7.9-3.7.13 |
| 2554687 CM-32205 | CVE-2020-28196: There is a denial of service vulnerability in the MIT Kerberos network authentication system, krb5. The lack of a limit in the “ASN.1” decoder could lead to infinite recursion and allow an attacker to overrun the stack and cause the process to crash. Vulnerable: <= 1.12.1+dfsg-19+deb8u5 Fixed: 1.12.1+dfsg-19+deb8u6 | 3.7.13 |
| 2554454 CM-32057 | The following vulnerability has been announced in the freetype / libfreetype6 packages: CVE-2020-15999: heap-based buffer overflow vulnerability in the handling of embedded PNG bitmaps in FreeType. Opening malformed fonts may result in denial of service or the execution of arbitrary code. Vulnerable: <= 2.5.2-3+deb8u4 Fixed: 2.5.2-3+deb8u5 | 3.7.13 |
| 2554332 CM-31981 | In an EVPN active/active environment, when one of the peers reboots and begins to refresh IP neighbor entries shared by the MLAG peer, some of the ARP messages might be dropped by the ARP policer of the MLAG peer. To work around this issue, increase the burst value of the ARP policers to 200 or higher. | |
| 2554232 CM-31929 | VXLAN encapsulated traffic is not routed to the next hop because the destination VTEP IP address is mis-programmed on the switch, which decapsulates the traffic unexpectedly. To work around this issue, restart switchd. | 3.7.12-3.7.13 |
| 2553876 CM-31695 | The following vulnerability has been announced in the ruby2.1 packages: CVE-2020-25613: WEBrick (bundled along with ruby2.1) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to “smuggle” a request. Vulnerable: <= 2.1.5-2+deb8u10 Fixed: 2.1.5-2+deb8u11. | 3.7.13 |
| 2553847 CM-31674 | The following vulnerabilities have been announced in the python3.4 packages: CVE-2019-20907: Avoid infinite loop with crafted tar file by improving header validation. CVE-2020-26116: Avoid injection of HTTP headers via the HTTP method without rejecting newline characters. Vulnerable: <= 3.4.2-1+deb8u8 Fixed: 3.4.2-1+deb8u9 | 3.7.13 |
| 2553738 CM-31622 | The following vulnerability has been announced in curl: CVE-2020-8231: In rare circumstances, when using the multi API of curl in combination with CURLOPT_CONNECT_ONLY, the wrong connection might be used when transfering data later. Vulnerable: <= 7.38.0-4+deb8u17 Fixed: 7.38.0-4+deb8u18 | 3.7.13 |
| 2553732 CM-31618 | 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 |
| 2553588 CM-31565 | 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 |
| 2553530 CM-31545 | 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 |
| 2553450 CM-31504 | 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 |
| 2553229 CM-31412 | 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 |
| 2553190 CM-31390 | The following vulnerabilities have been announced in libxml2: CVE-2017-8872: Global buffer-overflow in the htmlParseTryOrFinish function. CVE-2019-20388: A memory leak was found in the xmlSchemaValidateStream function of libxml2. Applications that use this library may be vulnerable to memory not being freed leading to a denial of service. CVE-2020-24977: Out-of-bounds read restricted to xmllint –htmlout. CVE-2020-7595: Infinite loop in xmlStringLenDecodeEntities can cause a denial of service. Vulnerable: <= 2.9.1+dfsg1-5+deb8u8 Fixed: 2.9.1+dfsg1-5+deb8u9 | 3.7.13 |
| 2553151 CM-31378 | The following security vulnerabilities have been announced in imagemagick:CVE-2017-12806: A memory exhaustion vulnerability was found in the function format8BIM, which allows attackers to cause a denial of service CVE-2019-13308, CVE-2019-13391: Heap-based buffer overflow in MagickCore/fourier.c in ComplexImages may cause a denial-of-service or other unspecified results Vulnerable: <= 6.8.9.9-5+deb8u20Fixed: 6.8.9.9-5+deb8u21 | 3.7.13 |

| 2553001 CM-31294 | When the following conditions exist, clagd might fail to establish a TCP control session across the subinterface (such as, peerlink.4094):* clagd uses an IPv6 link-local address (LLA) to establish the TCP connection (the clagd-peer-ip linklocal command configures an IPv6 LLA connection)* Subsequent VLAN changes are made to VLAN sub-interfaces or adding or removing SVIs This issue occurs because the hardware stores one entry per VRF to represent the IPv6 LLA. The hardware entry for the LLA is removed when another interface is changed because the software interfaces are represented by a single entity in hardware. As a result, packets destined to the local IPv6 LLA address are received on the port but do not get forwarded to CPU for further processing. To workaround this issue, use IPv4 addresses under peerlink.4094 and configure clagd to peer on IPv4 addresses. | 3.7.12-3.7.13 |
| 2552953 CM-31273 | The following vulnerability has been announced in the bind9 packages: CVE-2020-8622: Crafted responses to TSIG-signed requests could lead to an assertion failure, causing named, a Domain Name Server, to exit. This could be done by malicious server operators or guessing attackers. Vulnerable: <= 9.9.5.dfsg-9+deb8u19 Fixed: 9.9.5.dfsg-9+deb8u20 | 3.7.13 |
| 2552952 CM-31272 | The following vulnerability has been announced in the nss / libnss3 packages: CVE-2020-12403: The ChaCha20 symmetric key cipher algorithm did not correctly enforce the tag length which may have led to an out-of-bounds read and a lack of confidentiality. Vulnerable: <= 3.26-1+debu8u12 Fixed: 3.26-1+debu8u13 | 3.7.13 |
| 2552925 CM-31257 | On the EdgeCore AS-6712-32X, AS5812-54X and AS5812-54T switch models, the temp sensors (DIMM temp sensor) show ABSENT. The amber diagnostic light on the front of the switch might also be turned on due to this issue. These messages and the light are cosmetic issues only and do not otherwise impact the function of the switch. | 3.7.12-3.7.13 |
| 2552881 CM-31238 | 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 |
| 2552859 CM-31226 | Mellanox switches with the Spectrum ASIC fail to read PSU Fan/Temp sensors and report them as Absent. The following messages are observed in syslog:
| 3.7.13 |
| 2552756 CM-31158 | An issue has been found in python2.7, an interactive high-level object-oriented language. CVE-2019-20907: Opening a crafted tar file could result in an infinite loop due to missing header validation. Vulnerable: <= 2.7.9-2-ds1+deb8u5 Fixed: 2.7.9-2-ds1+deb8u6 | 3.7.13 |
| 2552647 CM-31086 | When you add a member to a bond that has a subinterface configured (such as peerlink.4094), the new member is assigned only the VLAN of the subinterface for forwarding. To work around this issue, bounce the bond or shutdown the new interface and use the remaining members over the bond. | 3.7.10-3.7.13, 4.2.0 |
| 2552608 CM-31055 | The following vulnerability has been announced: CVE-2019-20892: net-snmp before 5.8.1.pre1 has a double free in usm_free_usmStateReference in snmplib/snmpusm.c via an SNMPv3 GetBulk request. Fixed: 5.8.0-cl4.2.1u1, 5.8.0-cl3.7.14u1 | 3.7.13, 4.0.0-4.2.0 |
| 2552528 CM-31028 | 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 |
| 2552506 CM-31016 | Changing the order of the bridge ports might cause the bridge MAC address to change, which flaps the bridge and its ports. To work around this issue, manually set the MAC address of the bridge interface by adding hwaddress to the bridge stanza in the /etc/network/interfaces file. | 3.7.11-3.7.13, 4.0.0-4.2.0 |
| 2552352 CM-30914 | The following security vulnerabilities have been announced in the nss / libnss3 packages: CVE-2020-6829: Side channel attack on ECDSA signature generation CVE-2020-12400: P-384 and P-521 implementation uses a side-channel vulnerable modular inversion function CVE-2020-12401: ECDSA timing attack mitigation bypass Vulnerable: <= 3.26-1+debu8u11 Fixed: 3.26-1+debu8u12 | 3.7.0-3.7.13 |
| 2552351 CM-30913 | The following vulnerability has been announced in the libx11 packages: CVE-2020-14344: The X Input Method (XIM) client implementation in libX11 has some integer overflows and signed/unsigned comparison issues that can lead to heap corruption when handling malformed messages from an input method. Vulnerable: <= 1.6.2-3+deb8u2 Fixed: 1.6.2-3+deb8u3 | 3.7.0-3.7.13 |
| 2552301 CM-30885 | On a Mellanox switch with the Spectrum ASIC, you see LPC I2C driver errors similar to the following during boot:
| 3.7.13 |
| 2552298 CM-30882 | The following vulnerability has been announced in net-snmp: CVE-2020-15862: A privilege escalation involving the NET-SNMP-EXTEND-MIB support (which is enabled by default at compile-time). The fixed versions disable NET-SNMP-EXTEND-MIB support. Vulnerable: <= 5.8.0-cl3u11, <= 5.8.0-cl4u4 Fixed: 5.8.0-cl3.7.14u3, 5.8.0-cl4.2.1u1 | 3.7.13, 4.0.0-4.2.0 |
| 2552250 CM-30858 | A vulnerability was found in curl, a command line tool for transferring data with URL syntax. curl is installed by default on Cumulus Linux.CVE-2020-8177: When using when using -J (–remote-header-name) and -i (–include) in the same command line, a malicious server could force curl to overwrite the contents of local files with incoming HTTP headers. Vulnerable: <= 7.38.0-4+deb8u16 Fixed: 7.38.0-4+deb8u17 | |
| 2552249 CM-30857 | An issue has been found in luajit, a just in time compiler for Lua. CVE-2020-15890: An out-of-bounds read could happen because __gc handler frame traversal is mishandled. Vulnerable: 2.0.3+dfsg-3 Fixed: 2.0.3+dfsg-3+deb8u1 | |
| 2552205 CM-30827 | If the MAC address of an SVI changes, clagd does not update its permanent neighbor entry for the local interface, and it does not report the change to its MLAG peer. This leaves the MLAG peer in a state where its permanent neighbor for the MLAG peer’s SVI IP address continues to use the old MAC address, which causes routed traffic over this SVI to be dropped.To work around this issue, ifdown/ifup the SVI when a MAC address changes. | 3.7.12-3.7.13, 4.0.0-4.2.0 |
| 2551748 CM-30514 | 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 |
| 2551731 CM-30504 | When the OVSDB VTEP scale increases, the CPU utilization increases and eventually the switch (ptmd) fails to respond to the BFD, causing the BFD session to go down. As a result OVSDB cannot read the BFD socket status and outputs a warning in the ovs-vtepd debugs: PTM socket error: Bad file descriptor. | 3.7.12-3.7.13, 4.0.0-4.2.0 |
| 2551728 CM-30503 | In OVSDB high availability mode, if you create, then delete a binding, the FDB entry is not replaced and you see an error. | 3.7.12-3.7.13, 4.0.0-4.2.0 |
| 2551714 CM-30498 | There is a change to the default OVSDB bootstrapping process, where the script created now defaults to VLAN-aware bridge mode. If you want to use traditional bride mode, you need to force it by editing the ovs-vtep-ctl script generated by the bootstrap process. | 3.7.12-3.7.13, 4.0.0-4.2.0 |
| 2551693 CM-30486 | A host migrated to an 802.1X MAB port within the same broadcast domain fails to have the correct FDB entry installed if a dynamic FDB entry for that MAC address exists from previous connectivity in the broadcast domain. To work around this issue, manually delete the dynamic FDB entry that is associated with the uplink trunk port. | 3.7.12-3.7.13, 4.1.1-4.2.0 |
| 2551675 CM-30479 | When you restart clagd, the edge port setting on the peer link changes. | 3.7.2-3.7.13, 4.0.0-4.2.0 |
| 2551651 CM-30464 | The net show dot1x interface summary command output shows a MAC address with all zeros associated with a port. | 3.7.12-3.7.13, 4.0.0-4.2.0 |

| 2550606 CM-29982 | A VRRP role change over the EVPN network causes excessive BGP updates and connectivity issues to VIP for about one minute. | 4.1.1-4.2.0 |
| 2550375 CM-29838 | 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 |

3.7.13 Release Notes
Open Issues in 3.7.13
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3418046 None | 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 | 5.5.0-5.6.0 |
| 3376798 | On Broadcom switches, Cumulus Linux does not create the hardware bridging domain for a traditional bridge with a VXLAN interface during switchd restart.

| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |

| 2934939 | 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. | 3.7.12-3.7.16 | |

| 2546225 CM-27627 | 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 | |
| 2546203 CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior: * Both the inner and outer VLAN information is sent as part of VLAN TLVs in the LLDP packet. * If the outer VLAN ID is the same as the inner VLAN ID, only one VLAN TLV is sent with that VLAN ID in the LLDP packet. | 3.7.11-3.7.16 | |
| 2546131 CM-27581 | 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 | |

| 2543211 CM-25890 | 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 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2542979 CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-4.1.1 | 4.2.0-4.4.5 |
| 2542945 CM-25740 | 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 | |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |

| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | 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 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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 | |
| 2538256 CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.7.2-4.0.1 | 4.1.0-4.4.5 |
| 2537820 CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2537699 CM-23075 | 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 CM-23021 | 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 | |
| 2537378 CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.7.1-3.7.16 | |

| 2536384 CM-22386 | 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 | |

| 2535986 CM-22041 | 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 CM-22020 | 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 | |

| 2549397 CM-29322 | When the BGP Multi-protocol Unreach NLRI attribute is received in a BGP update without a next hop attribute, the BGP session is brought down unexpectedly. RFC 4760 defines that the next-hop attribute is not required for updates containing MP_UNREACH_NLRI. | 3.7.12 |
| 2548673 CM-29044 | A large number of flapping peers causes FRR to require a corresponding update to internal data structures that track peer information. Updating this internal data structure does not delete links that are down due to the flapping. The size of this array then grows to contain both current peers as well as peers that should have been deleted during the flap processing. The contents of this array is processed by FRR to poll the links, which consumes CPU for all items in the array. This additional polling consumes more CPU than necessary but has no functional impact. To work around this issue, restart FRR. | 3.7.11-3.7.12, 4.0.0-4.1.1 |
| 2548659 CM-29037 | When a link flap occurs while IPv6 traffic traverses interfaces, a kernel panic may occur with the following logs printed to the console:
| 3.7.12 |
| 2548585 CM-28995 | After you flap an MLAG peerlink, a rare condition might occur where routes and neighbors for VXLAN-enabled VLANs are misprogrammed as non-VXLAN routes and neighbors due to VNI state transitions. This results in a forwarding failure for traffic destined to these misprogrammed routes and neighbors. Note: Do not flap a VNI interface manually. The only expected time for a VNI interface to go down is when the MLAG secondary switch brings the VNIs protodown during a peer link failure where the backup IP address is still active. To recover from this condition, restart switchd with the sudo systemctl restart switchd command. | 3.7.10-3.7.12, 4.1.0-4.1.1 |
| 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.

| 2547880 CM-28488 | The following CVEs were announced that affect the cron package. All of these require untrusted local user access. CVE-2017-9525 is a local user privilege escalation attack: In the cron package through 3.0pl1-128 on Debian, and through 3.0pl1-128ubuntu2 on Ubuntu, the postinst maintainer script allows for group-crontab-to-root privilege escalation via symlink attacks against unsafe usage of the chown and chmod programs. CVE-2019-9704, CVE-2019-9705, CVE-2019-9706 are local user denial of service attacks. Note: the fix for CVE-2019-9705 imposes a limitation on the length of a crontab file (the vulnerability was that an unlimited size crontab file could cause excessive memory consumption). https://security-tracker.debian.org/tracker/DLA-1723-1 Vulnerable: <= 3.0pl1-cl3u1 Fixed: 3.0pl1-cl3u2 | 3.7.12 |

Note: The exact amount of CPU usage varies in each network based on a number of factors; however, it is unusual for lldpd to consume more than 30% CPU for an extended period of time.To work around this issue, you can do one of the following: * If the large number of VLANs is not absolutely necessary, manually prune the VLAN allowed list (if you use the range 1-2999, modify the bridge-vids list to include the VLANs being used).* Stop the lldpd service. (This approach might be undesirable if the switch is providing services that rely on LLDP such as Voice VLAN.) To stop the lldpd service (runtime setting), run the sudo systemctl stop lldpd.service command. To disable the lldpd service upon boot, run sudo systemctl disable lldpd.service. | 3.7.11-3.7.12, 4.0.0-4.0.1 |
| 2543792 CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:
| 3.7.9-3.7.12, 4.0.0-4.0.1 |
| 2543648 CM-26138 | You cannot specify a source and destination MAC address in an ERSPAN ebtables rule. For example, the following rule does not work:
| 3.7.6-3.7.12, 4.0.0-4.1.1 |
| 2543472 CM-26024 | On switches with the Spectrum ASIC, the underlay hashes VXLAN packets for a given overlay flow randomly. To work around this issue, configure the ECMP hash seed to the same value on the EVPN egress leaf switches. | 3.7.7-3.7.12, 4.0.0-4.0.1 |
| 2542767 CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12, 4.0.0-4.0.1 |
| 2535845 CM-21898 | On a Trident3 switch, IGMP packets are not policed by the police rule in the 00control ACL file. The packets are policed by the catchall policer in the 99control ACL file instead.-A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police –set-mode pkt –set-rate 100 –set-burst 100To work around this issue, let the CPU bound IGMP packet hit the following rule and change the policer rate to a desired value for IGMP packets: -A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police –set-mode pkt –set-rate 100 –set-burst 100Typically, the destination MAC address 01:00:5e:xx:xx:xx is used only for PIM/IGMP control and data stream packets. However, this workaround cannot handle data stream multicast packets that are not TCP/UDP; this is not typically done. | 4.0.0-4.0.1 |

| 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. | 3.7.0-3.7.16, 4.3.1-4.4.5 | |
| 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 | 5.4.0-5.6.0 |
| 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, 5.0.0-5.6.0 | |

| 2934939 | 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. | 3.7.12-3.7.16 | |

| 2885238 | The following vulnerabilities have been announced in bluez, the Linux Bluetooth protocol stack:CVE-2019-8921: SDP infoleak; the vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation of BlueZ. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data CVE-2019-8922: SDP Heap Overflow; this vulnerability lies in the SDP protocol handling of attribute requests as well. By requesting a huge number of attributes at the same time, an attacker can overflow the static buffer provided to hold the response CVE-2021-41229: sdp_cstate_alloc_buf allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash Vulnerable: <= 5.43-2+deb9u2~deb8u3Fixed: 5.43-2+deb9u2~deb8u4 | 3.7.0-3.7.15 | 3.7.16 |

| 2553001 CM-31294 | When the following conditions exist, clagd might fail to establish a TCP control session across the subinterface (such as, peerlink.4094):* clagd uses an IPv6 link-local address (LLA) to establish the TCP connection (the clagd-peer-ip linklocal command configures an IPv6 LLA connection)* Subsequent VLAN changes are made to VLAN sub-interfaces or adding or removing SVIs This issue occurs because the hardware stores one entry per VRF to represent the IPv6 LLA. The hardware entry for the LLA is removed when another interface is changed because the software interfaces are represented by a single entity in hardware. As a result, packets destined to the local IPv6 LLA address are received on the port but do not get forwarded to CPU for further processing. To workaround this issue, use IPv4 addresses under peerlink.4094 and configure clagd to peer on IPv4 addresses. | 3.7.12-3.7.13 | 3.7.14-3.7.16, 4.2.0-4.4.5 |

| 2548962 CM-29165 | With FRR or OSPF, you might see an inconsistent link-state advertisement. For example, when you configure the OSPF default originate route as metric-type 1 with a specific metric, Cumulus Linux shows the default originate route as an external metric-type 2 route with the default metric in the database. This issue typically occurs when both IPv4 and IPv6 default routes exist in the routing table. | 3.7.12-4.1.1 | 4.2.0-4.4.5 |

| 2548673 CM-29044 | A large number of flapping peers causes FRR to require a corresponding update to internal data structures that track peer information. Updating this internal data structure does not delete links that are down due to the flapping. The size of this array then grows to contain both current peers as well as peers that should have been deleted during the flap processing. The contents of this array is processed by FRR to poll the links, which consumes CPU for all items in the array. This additional polling consumes more CPU than necessary but has no functional impact. To work around this issue, restart FRR. | 3.7.11-4.1.1 | 4.2.0-4.4.5 |

| 2548585 CM-28995 | After you flap an MLAG peerlink, a rare condition might occur where routes and neighbors for VXLAN-enabled VLANs are misprogrammed as non-VXLAN routes and neighbors due to VNI state transitions. This results in a forwarding failure for traffic destined to these misprogrammed routes and neighbors. Note: Do not flap a VNI interface manually. The only expected time for a VNI interface to go down is when the MLAG secondary switch brings the VNIs protodown during a peer link failure where the backup IP address is still active. To recover from this condition, restart switchd with the sudo systemctl restart switchd command. | 3.7.10-4.1.1 | 4.2.0-4.4.5 |

| 2547068 CM-28046 | 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 | 4.3.0-4.4.5 |
| 2546991 CM-28003 | The FRR service does not provide a way for automation to know if the configuration applied properly.

| 2546950 CM-27982 | switchd crashes when dynamic VRF route leaking is enabled and the following is true:* The default route is leaked from VRF1 to VRF2 * Hardware-based dynamic VRF route leaking is configured ( vrf_route_leak_enable_dynamic is set to TRUE in the /etc/cumulus/switchd.conf file).You might see logs similar to the following in /var/log/syslog:
To work around this issue, use a route map to filter the default route (the source VRF is imported into the destination VRF). | 3.7.10-4.1.1 | 4.2.0-4.4.5 |
| 2546895 CM-27957 | 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). If the restart fails multiple times in a short time period, run the sudo systemctl reset-failed command followed by the sudo systemctl restart switchd command. | 3.7.11-3.7.16, 4.0.0-4.4.5 | |

| 2546451 CM-27737 | On the EdgeCore AS7326-56X switch, you might see the RPM of certain fans run over the maximum threshold. | 3.7.11-3.7.16 | |
| 2546385 CM-27698 | SNMP ifLastChange reports link transitions when there are none. | 3.7.6-3.7.16 | |
| 2546225 CM-27627 | 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 | |
| 2546203 CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior: * Both the inner and outer VLAN information is sent as part of VLAN TLVs in the LLDP packet. * If the outer VLAN ID is the same as the inner VLAN ID, only one VLAN TLV is sent with that VLAN ID in the LLDP packet. | 3.7.11-3.7.16 | |
| 2546141 CM-27586 | CPU usage might be higher than normal if you have a high number of interfaces x VLANs and lldpd is active. This issue is introduced with code changes in Cumulus Linux 3.7.11, where VLAN information is now available for LLDP to advertise to neighbors ([https://docs.cumulusnetworks.com/version/cumulus-linux-37/Layer-2/Link-Layer-Discovery-Protocol/#vlan-dot1-tlv]). You might see high CPU usage even if VLAN (dot1) TLV configuration is disabled.To check if lldpd is the heavy CPU resource user, run the following command:
Alternatively, check for messages in the /var/log/syslog directory similar to:
Note: The exact amount of CPU usage varies in each network based on a number of factors; however, it is unusual for lldpd to consume more than 30% CPU for an extended period of time.To work around this issue, you can do one of the following: * If the large number of VLANs is not absolutely necessary, manually prune the VLAN allowed list (if you use the range 1-2999, modify the bridge-vids list to include the VLANs being used).* Stop the lldpd service. (This approach might be undesirable if the switch is providing services that rely on LLDP such as Voice VLAN.) To stop the lldpd service (runtime setting), run the sudo systemctl stop lldpd.service command. To disable the lldpd service upon boot, run sudo systemctl disable lldpd.service. | 3.7.11-3.7.12, 4.0.0-4.0.1 | 3.7.13-3.7.16, 4.1.0-4.4.5 |
| 2546131 CM-27581 | 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 | |
| 2546010 CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.16 | |
| 2545997 CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.16 | |

| 2544953 CM-26905 | When you update the hostname of a switch with the NCLU net add hostname command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.16, 4.0.0-4.4.5 | |
| 2544904 CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-4.1.1 | 4.2.0-4.4.5 |
| 2544829 CM-26829 | Frames received with a VLAN tag of 0 on an interface configured as a bridge port and forwarded to the CPU for processing might appear tagged with the native VLAN when viewed with tcpdump. | 3.7.8-3.7.16 | |

| 2543164 CM-25859 | 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 CM-25815 | 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 | |
| 2543058 CM-25798 | The IP neighbor entry for a link-local next hop is not installed by FRR, which results in a forwarding failure for routes via that next hop. This is a rare problem that occurs with IPv4 route exchange over IPv6 GUA peering with no IPv4 addresses on the interfaces. To work around this issue, flap the peering to the peer router (which might be a route reflector) to recover. To avoid this issue, configure IPv6 router advertisements on the connecting interfaces. | 3.7.7-3.7.16 | 4.0.0-4.4.5 |
| 2543052 CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:
You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.16 | 4.0.0-4.4.5 |
| 2543044 CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.16 | 4.0.0-4.4.5 |
| 2542979 CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-4.1.1 | 4.2.0-4.4.5 |
| 2542945 CM-25740 | 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 | |
| 2542767 CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12, 4.0.0-4.0.1 | 3.7.13-3.7.16, 4.1.0-4.4.5 |
| 2542310 CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.16 | |
| 2542305 CM-25400 | 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 CM-25397 | 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 CM-24894 | 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 | |
| 2541165 CM-24878 | On the Dell N3048EP-ON switch, UPOE is supported only on ports 1 thru 12. (UPOE uses all four pairs of standard Ethernet cabling whereas PoE delivers power over two twisted pairs.) When you plug a UPOE device in a port higher than port 12, poectl reports that four_pair_mode_enabled is true. However, this configuration is not supported on the port so poectl should report that four_pair_mode_enabled is false. | 3.7.6-3.7.16 | |
| 2541029 CM-24799 | 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 | |
| 2540950 CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-4.1.1 | 4.2.0-4.4.5 |
| 2540885 CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.16 | |
| 2540863 CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.16 | |
| 2540753 CM-24618 | 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 CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540352 CM-24435 | 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 CM-24426 | 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 CM-24379 | 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 CM-24350 | 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 CM-24343 | 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 CM-24332 | 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 CM-24272 | 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 CM-24271 | 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 CM-24270 | 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 CM-24262 | 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 CM-24241 | 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 CM-24222 | 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 CM-24035 | 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 CM-23825 | 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 | |
| 2539081 CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev command. | 3.7.0-3.7.16 | 4.0.0-4.4.5 |
| 2538875 CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.16 | |
| 2538790 CM-23665 | 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 CM-23584 | 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 CM-23570 | 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 | |
| 2538302 CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.16 | |
| 2538294 CM-23417 | 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</ |
