Open Issues in 5.6.0
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4154369 | When adding or removing routes in a virtual router with numerous configured routes, you might see certain IP addresses being routed incorrectly. This can result in packets exiting through incorrect ports or discarded packets. | 5.5.1-5.11.0 | 5.11.1-5.12.1, 5.12.0-5.12.1 |
| 4004453 | The NVUE commands to delete SNMP users, and change authentication passwords and encryption passphrases are not successful. | 4.3.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3982222 | When you enable SPAN on a bridge member, an ARP or Gratuitous ARP received during a failover event between locally attached redundant devices, such as load balancers, might fail to update the bridge MAC table to point to the interface with the newly active load balancer. To work around this issue, remove the SPAN configuration from the bridge member or ensure that the load balancer generates non-ARP traffic after the failover to properly update the bridge MAC table. | 5.4.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3980924 | When adding or removing routes in a virtual router with numerous configured routes, you might encounter incorrect routing of certain IP addresses. This can result in packets exiting through incorrect ports or being discarded. | 5.5.1-5.12.1 | |
| 3955615 | Cumulus Linux does not recognize QSFP_CMIS optical modules correctly. | 5.6.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3949367 | If you use NVUE to create an SNMP user with a password, then delete and recreate the user with additional encryption passwords (such as DES or AES), SNMP authorization fails for that user. | 5.3.1-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3927016 | Following an EVPN extended mobility event, where a host with IP address A and MAC address A moves within the fabric and now resides at IP address A and MAC address B, you might see traffic destined to this host experience drops as the flow is software forwarded on the egress VTEP. | 5.0.1-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3917601 | If a packet containing an all zero source MAC address (00:00:00:00:00:00) is learned on the ASIC, switchd sends the learn notification to the kernel but the kernel rejects the MAC address as invalid. The ASIC continuously sends the mac-learn notifications, which wastes CPU resources. To work around this issue, configure ACLs to match on the all-zero source MAC address and drop the invalid packets. | 5.5.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3897227 | During an LLDP update storm while deleting or adding LLPD neighbors, PTMD crashes as a result of mishandling multi-threaded LLPD processing. | 5.5.1-5.9.2 | 5.10.0-5.12.1 |
| 3895042 | After an NMS station does a full SNMP walk on the switch, you see the following message every 5 minutes:snmp : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/cumulus/bin/poectl -j -a This issue occurs because poectl is called on non-PoE switches. To work around this issue, remove or comment out the poetcl call from the /etc/snmpd.conf file, then restart the snmpd process with the sudo systemctl snmpd restart command#snmp ALL = NOPASSWD: /usr/cumulus/bin/poectl -j -a | 4.4.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3863858 | VRR interfaces might show dadfailed on their IPv6 link-local address. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3859422 | On rare occasions when certain events occur, such as changes to the topology in the network, when a bond comes online and directly transits to an STP blocking state, the slave ports might still be in a forwarding state. As a result, traffic is forwarded on a blocked port. | 5.2.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3854807 | When you enable Optimized Multicast Flooding (OMF) and change VLAN configuration, a few ports might carry multicast traffic even when they are not in the MDB or they are not router ports. | 5.6.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3854800 | The switch forwards multicast traffic to the CPU when PIM is enabled globally, regardless of the interface configuration. | 5.6.0-5.9.1 | 5.9.2-5.12.1, 5.10.0-5.12.1 |
| 3824750 | With the nvidia.nvue Ansible module, NVUE honors input from the Ansible module only; if you do not provide the full configuration, NVUE generates an exception. To work around this issue, always provide the full configuration. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3782996 | If you have installed a large number ACLs, you might see a switchd memory leak over a period of time that stops the switchd process because it is out of memory . | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3782543 | When you configure the BGP setting bgp max-med on-startup with vtysh, the MED on some peers might not be set to 4294967294 as expected on startup. The max-med might also fail to reset after the startup timer expires. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3773177 | When you try to upgrade a switch from Cumulus Linux 5.5 or earlier to 5.8.0 or later with package upgrade, you see errors for expired GPG keys that prevent you from upgrading. To work around this issue, install the new keys with the following commands, then upgrade the switch.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/c/cumulus-archive-keyring/cumulus-archive-keyring_4-cl5.6.0u5_all.deb | 4.0.0-4.4.5, 5.0.0-5.12.1 | |
| 3766994 | Cumulus Linux 5.6 and 5.7 do not include FRR log rotation, which can result in a very large log file that affects disk usage. To work around this issue, run the following commands as the cumulus user on the Cumulus Linux 5.6 or 5.7 switch. The commands do not impact any other system function.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/f/frr-logrotate/frr-logrotate_8.4.3-0+cl5.7.0u1_amd64.deb | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3765395 | The nv unset nve vxlan flooding and nv set nve vxlan flooding enable off commands do not disable BUM flooding. To work around this issue, disable BUM flooding with vtysh commands:leaf01# configure terminal | 5.5.0-5.8.0 | 5.9.0-5.12.1 |
| 3753050 | On Spectrum 1 switches, switchd might crash due to an SDK health event or error. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3751952 | ifupdown2 tries to set the multicast database hash elasticity (bridge-hashel attribute) with a value of 4096. However, this attribute is now deprecated in the Linux kernel and the value is always 16. | 5.5.1-5.7.0 | 5.8.0-5.12.1 |
| 3739008 | The Lenovo MSN4600-VS2RC (PN SSG7B27990 Back-to-Front/C2P Airflow) might run the fan tray fans at a high speed because the software believes the PSU fans are running in the wrong direction. | 5.5.1-5.8.0 | 5.9.0-5.12.1 |
| 3738626 | If you configure a VNI before an SVI, you can’t add or remove the VRR address from the SVI. To work around this issue, configure the SVI before the VNI. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3730904 | When sending untagged frames to the CPU with an MTU higher than the SVD (single VXLAN device) MTU, the kernel might crash. | 5.4.0-5.8.0 | 5.9.0-5.12.1 |
| 3713419 | When monitoring system statistics and network traffic with sFlow, an aggressive link flap might produce a memory leak in the sFlow service hsflowd. | 5.1.0-5.7.0 | 5.8.0-5.12.1 |
| 3712007 | In RSTP mode when there is a bridge port flap, Cumulus Linux flushes, then re-adds dynamic MAC addresses on the peer link, which might cause short traffic disruption. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3710396 | In an eBGP multihop configuration with dynamic neighbors, Cumulus Linux does not update the configured TTL but uses the MAXTTL instead. This issue is only observed with dynamic peers. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3702431 | Traditional SNMP snippets do not take effect unless you first enable SNMP with the NVUE nv set service snmp-server enable on and nv set service snmp-server listening-address commands. Alternatively, you can use the equivalent REST API methods. | 5.4.0-5.8.0 | 5.9.0-5.12.1 |
| 3698680 | If you run the ifreload -a command when ACLs exist but nonatomic update mode is set in the switchd.conf file, traffic pauses on unaffected interfaces. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3696061 | When the MAC address of a neighbor changes, the zebra IP routing manager might crash. | 5.2.1-5.6.0 | 5.7.0-5.12.1 |
| 3695430 | When you configure extended nexthop encoding for a peer group, the peers in the group do not inherit the configuration. To work around this issue, configure extended nexthop encoding on each individual peer in the group. NVIDIA recommends that you upgrade to Cumulus Linux 5.6 or later to avoid this issue. | 5.4.0-5.6.0 | 5.7.0-5.12.1 |
| 3686389 | When you use NVUE commands to configure an untagged VLAN (PVID) on a bridge to a non-default value, nv show bridge commands still indicate that the untagged VLAN is 1 (the default value). The untagged VLAN you configured is properly set on bridge ports, but displays incorrectly in operational NVUE show commands. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3684998 | DHCP lease information is not collected in the cl-support file. | 4.3.0-5.6.0 | 5.7.0-5.12.1 |
| 3684268 | When multiple interfaces have addresses in the same network, deleting one of them might cause the wrong connected route from being deleted. | 5.6.0 | 5.7.0-5.12.1 |
| 3671288 | Routes and/or next-hops will no-longer be installed in kernel, and traffic related to these routes and/or next-hops will not be forwarded correctly. Flapping of EVPN prefixes from BGP updates and withdraws sometimes causes a race condition where the routes are never re-installed. An example of a trigger that can lead to this problem is a flapping peerlink. A reboot of each switch with missing routes will recover from this issue. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3669935 | When you add or delete VXLAN VNI and VLAN interfaces, a memory leak might occur in switchd. | 5.6.0 | 5.7.0-5.12.1 |
| 3668939 | When you enable MIB 1.3.6.1.4.1.40310.1 in the snmpd.conf file, you might see high CPU usage by the snmpd service. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3668809 | SN2410 switches manufactured or sold by OEMs (not Mellanox) might contain fans that do not support system fan direction detection. As a result, the following messages occur in the log:/usr/sbin/smond : : Path /run/hw-management/thermal/fan1_dir does not exist/usr/sbin/smond : : Path /run/hw-management/thermal/fan2_dir does not exist smond has been modified to determine dynamically (at run-time) if the fan has the capability. To drop the messages before they get to the log, create a file, such as /etc/rsyslog.d/18-drop_fan_dir_msgs.conf with the following contents, then restart rsyslogd with the systemctl restart rsyslog command# The lines below cause the offending message to be dropped from all logs:msg, ereregex, “.*Path /run/hw-management/thermal/fan[1-8]_dir does not exist” stop | 5.6.0 | 5.7.0-5.12.1 |
| 3664986 | If a core file is generated with a space in the name, Cumulus Linux generates cl-support files until the file is removed. To work around this issue, rename the core file without the space character. The next cl-support file generated will be moved into the cl-support archive and removed from the filesystem. | 5.6.0 | 5.7.0-5.12.1 |
| 3663182 | Changing non-default BGP timers with NCLU or vtysh commands sets the hold time and keep alive interval to 0 seconds. To work around this issue, restart the FRR service with the sudo systemctl restart frr.service command. | 5.3.1-5.6.0 | 5.7.0-5.12.1 |
| 3662354 | When you enable the FRR SNMP agent (agentx) and configure routing adjacencies with short timers (dead, keepalive, and hold time), the routing adjacencies might go down in certain scenarios; for example when you have frequent or concurrent client SNMP requests, you use custom SNMP MIB extensions, you poll OIDs with large responses, or during high CPU load. To work around this issue, you can increase the routing adjacency timers to accommodate SNMP processing. | 5.6.0 | 5.7.0-5.12.1 |
| 3655043 | After you upgrade to Cumulus Linux 5.6.0 with package upgrade, configuration changes you make with NVUE commands do not apply and you see the error message Invalid config [rev_id: 4] Default profile parameters can not be modified. Modification allowed on user created profiles. To workaround this issue:1. Remove the PTP configuration using the nv unset service ptp 1 enable syntax2. Save the configuration nv config apply. 3. Re-add the PTP config. Note: this procedure results in a switchd restart which will have an impact on the data plane. | 5.6.0 | 5.7.0-5.12.1 |
| 3655027 | If you create a new snippet with the same name as a snippet you deleted, you receive a warning message. To work around this issue, create the new snippet with a different name than any removed snippets. | 5.6.0 | 5.7.0-5.12.1 |
| 3650661 | Configuration changes to an already applied custom flexible snippet that includes a service restart does not restart the service when you apply the patch. | 5.6.0 | 5.7.0-5.12.1 |
| 3646119 | If you have VRFs configured and you change the global ASN in FRR, BGP crashes. To work around this issue, don’t unset more than one BGP instance at a time if one of the router bgp instances has VRF leaking configured. | 5.6.0 | 5.7.0-5.12.1 |
| 3644473 | When bulk interface flaps trigger, Cumulus Linux does not process the route.route_preferred_over_neigh=both configuration correctly due to the sequence of the events that occur when switchd creates and processes the route or neighbor and nexthop group. | 5.6.0 | 5.7.0-5.12.1 |
| 3643624 | The help text for the NVUE policer command nv set acl incorrectly indicates that the policer mode units are in bits per second. NVUE configures policers using bytes per second. | 5.6.0 | 5.7.0-5.12.1 |
| 3639058 | When you run the nv show service ntp command, you see an error message instead of the expected output. | 5.6.0 | 5.7.0-5.12.1 |
| 3632843 | When the switch receives a type-5 route in BGP and there is a network statement for the same prefix, BGP sometimes removes the request to track next hops from FRR. As next hop reachability changes, BGP no longer reacts to the change. To work around this issue, run the clear bgp * command for all peerings. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3630492 | On the NVIDIA SN2201 switch, the ledmgrd -d command output shows the system and PSU LED status as orange when the physical LED is green. | 5.5.1-5.7.0 | 5.8.0-5.12.1 |
| 3627913 | The switch drops untagged VLAN traffic on single VXLAN bridge ports. | 5.6.0 | 5.7.0-5.12.1 |
| 3616643 | NVUE commands to set a route map exit policy match produce incorrect configuration in the /etc/frr/frr.conf file. | 5.6.0 | 5.7.0-5.12.1 |
| 3616338 | When you reboot an MLAG switch with 3000 or more VNIs, there might be extended traffic loss during reboot. To work around this issue, configure the clagd service initDelay to 300 seconds with the nv set mlag init-delay 300 command. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3614286 | To avoid unnecessary traffic loss, ifreload (ifupdown2) only flaps a bond to reset its MAC address when the bond MAC address is not present on any of the bond’s interfaces. Previously, ifupdown2 enforced the bond MAC address to be set to the MAC address of the first interface. | 5.6.0-5.7.0 | 5.8.0-5.12.1 |
| 3613258 | With VM migration from one VTEP to another, traffic loss might occur during a MAC move as locally learned MAC addresses are frequently refreshed between switchd and the kernel. | 5.2.1-5.6.0 | 5.7.0-5.12.1 |
| 3612959 | The interface name for a VLAN subinterface does not show correctly; the VLAN is appended to the interface again. | 5.6.0 | 5.7.0-5.12.1 |
| 3611215 | In an EVPN multihoming configuration, the switchd service produces error messages similar to the following:2023-09-07T15:45:56.055477+02:00 switch1 switchd7903: hal_mlx_flx_acl.c:2388 hal_mlx_flx_region_pull_bulk_counters failedThese error messages do not affect how the switch functions; however the messages fill up the switchd logs, which is not desirable. | 5.6.0 | 5.7.0-5.12.1 |
| 3610967 | In an EVPN symmetric routing configuration, running the NVUE nv set vrf command to derive layer 3 VNIs automatically might result in duplicate VLAN entries in the system. This most often occurs at scale when many VRFs have similar names. To work around this issue, manually specify a unique VLAN for each VRF. | 5.3.0-5.8.0 | 5.9.0-5.12.1 |
| 3610611 | Cumulus Linux assigns an IPv4 and IPv6 loopback address to a VRF interface by default. As a result, ping and route lookups for unique remote IP addresses on different VTEPs might not work if there is no source IP on the switch that belongs to the same subnet. To work around this issue, remove the loopback address on the VRF with the nv unset vrf ping command to use a source address (such as an SVI address) with the ip vrf exec command. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3609128 | When you use vi with root or sudo, visual mode is enabled by default due to a missing vimrc configuration file. This makes it difficult to copy and paste into vi. In CL5.7.0, the default configuration now includes set mouse-=aIn addition, the CL5.7.0 default configuration for vi now disables modelines, which can be a security risk. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3608014 | Software MAC learning might not work for a bridged VLAN subinterface on a bond (such as bond1.100) if you remove a VLAN subinterface completely from the configuration, then add it back with an identical configuration. To work around this issue, restart switchd. | 5.6.0 | 5.7.0-5.12.1 |
| 3606739 | The thermal control service, hw-management-tc.service, stops and switch fan speeds run at 100% when the ASIC temperature can’t be read. This can occur if the SDK is not started. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3603237 | If the secondary MLAG peer continuously reboots, you might experience momentary traffic loss. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3600588 | You can’t reset the root password by booting into Cumulus Linux single-user recovery mode. To work around this issue, follow the steps in https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-56/Monitoring-and-Troubleshooting/Single-User-Mode-Password-Recovery/. | 5.6.0 | 5.7.0-5.12.1 |
| 3599699 | Cumulus Linux assigns an IPv4 and IPv6 loopback address to a VRF interface by default. As a result, ping and route lookups for unique remote IP addresses on different VTEPs might not work if there is no source IP on the switch that belongs to the same subnet. To work around this issue, remove the loopback address on the VRF with the nv unset vrf command. Only remove the loopback address if you are not running NTP as NTP requires a loopback address to work. Alternatively, you can change the ping command to use a source address (such as an SVI address) with the ip vrf exec command. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3597456 | NVUE does not allow you to use the reserved name lo in an interface name. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3591918 | The nv action disconnect system aaa user command does not clear all the open sessions. To work around this issue, run the command as many times as the number of sessions to clear all the sessions. | 5.6.0-5.12.1 | |
| 3590394 | Under rare conditions, running NVUE commands that capture output larger than 4k bytes from Linux tools or utilities might result in failures with 500 INTERNAL SERVER ERROR or Unrecoverable internal error messages. This issue occurs when there are non-ascii characters in large outputs that Cumulus Linux can’t decode. This failure is observed only in Cumulus Linux 5.6 and earlier. | 5.6.0 | 5.7.0-5.12.1 |
| 3587393 | If you use the NVIDIA SN5600 (Spectrum-4) switch with Ixia test equipment, you might experience delayed link up due to intermittent link flaps. To work around this issue when using copper cables:
To work around this issue when using fiber cables:
| 5.6.0-5.12.1 | |
| 3585467 | NVUE and ip link show traditional bridge VLAN subinterface counts incorrectly. The ingress (Rx) count increments correctly but the egress (Tx) count does not increment. This issues occurs because the hardware does not support transmit counters for a VLAN subinterface; therefore, no statistics from the hardware are updated. Statistics for software forwarded packets show correctly. | 5.0.0-5.6.0 | 5.7.0-5.12.1 |
| 3582826 | When you enable the FRR SNMP agent (agentx) and configure routing adjacencies with short timers (dead, keepalive, and hold time), the routing adjacencies might go down in certain scenarios; for example when you have frequent or concurrent client SNMP requests, you use custom SNMP MIB extensions, you poll OIDs with large responses, or during high CPU load. To work around this issue, you can increase the routing adjacency timers to accommodate SNMP processing. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3580435 | On the NVIDIA SN2410 switch with an Innodisk SSD, you might see the following message in syslog:smartd[501]: Device: /dev/sda [SAT], CHECK POWER STATUS spins up disk (0x00 -> 0xff)This is a cosmetic issue and does not affect how the switch operates. To prevent this message from occurring, run the hdparm -S 24 /dev/sda command to change the HD timeout. | 5.3.1-5.6.0 | 5.7.0-5.12.1 |
| 3576961 | The NVUE command to clear all ACL counters at once is not available. To work around this issue, run the cl-acltool -Z all command to reset the statistics for all ACL rules. | 5.5.1-5.6.0 | 5.7.0-5.12.1 |
| 3575800 | When you configure the peerlink interface with NVUE but do not configure the necessary MLAG parameters with nv set mlag commands (such as the backup IP address, peer IP address, and MLAG MAC address), NVUE apply fails with the following message:
| 5.6.0 | 5.7.0-5.12.1 |
| 3573800 | After you apply a change to the router MAC address on an SVI with the ifreload -a command, the old router MAC address still remains in the FDB table. To work around this issue, remove the old router MAC address with the sudo bridge fdb del <old_mac> dev bridge vlan <vlan_id> command. | 5.3.1-5.6.0 | 5.7.0-5.12.1 |
| 3567708 | In an EVPN multihoming environment with VRRP, when the master VRRP router fails, the standby router takes around 30 seconds to become active. | 5.3.1-5.6.0 | 5.7.0-5.12.1 |
| 3566980 | When running DHCP relay for IPv6 and a downstream interface flaps more than once, relaying might stop working. To recover, restart the dhcrelay6 service, making sure the specified downstream interfaces are up and running. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3556762 | On rare occasions, SPT switchover might not happen cleanly in PIM resulting in some dropped packets. If you use PIM-SM to replicate EVPN BUM traffic, you might see a brief drop of multicast traffic before recovering due to normal PIM-SM traffic timeout. | 5.5.0-5.12.1 | |
| 3554231 | CVE-2023-38408: The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009 Mitigation: Do not use ssh-agent forwarding (the man page for ssh_config says that “agent forwarding should be enabled with caution”), or start the ssh-agent program with the -P option to allow only specific PKCS#11 libraries (or none with -P ‘'). For Cumulus Linux 5.7.0, the /usr/bin/ssh-agent program has all permissions turned off (chmod 0) to prevent its execution if a vulnerable version is detected. | 4.0.0-4.3.1, 5.0.0-5.6.0 | 4.3.2-4.4.5, 5.7.0-5.12.1 |
| 3546857 | The nv show bridge vlan command does not show tagged and untagged VLAN information for the bridge | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3541653 | During warm boot with layer 3 traffic, you might experience packet loss for approximately 15 milliseconds. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3540510 | 400Gx8 ports only support traffic line rate with packets that are larger than 172 bytes. | 5.6.0-5.12.1 | |
| 3538321 | In rare cases, an STP topology change on PTP over a VLAN can result in the switch losing the slave state and one of the ports might remain in an uncalibrated state. To work around this issue, toggle the port that is in the uncalibrated state up and down so that one of the ports is selected as the slave. | 5.6.0-5.12.1 | |
| 3534718 | The BGP command to suppress longer prefixes inside the aggregate address before sending updates (nv set vrf or vtysh router bgp ) does not suppress more specific routes from being exported into the EVPN routing table and advertised as EVPN type-5 routes. To work around this issue, announce EVPN type-5 routes by adding an additional outbound policy or export policy to filter out the more specific routes. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3533272 | If you set an OSPF network and define the subnet using a host address (such as 10.1.1.2/24) instead of the (starting) subnet network address (such as 10.1.1.0/24), you can’t unset the prefix with the nv unset vrf default router ospf area network command. Avoid defining the subnet using a host address when setting an OSPF network. | 5.6.0 | 5.7.0-5.12.1 |
| 3522524 | FRR does not allow eBGP multi hop configuration on unnumbered BGP neighbors. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3517739 | When you connect the SN5600 switch to third party test equipment (such as IXIA) using copper cables, 100G, 200G, 400G, and 800G links do not come up. To work around this issue, use fiber optic cables when testing an SN5600 switch with IXIA for 100G, 200G, 400G, and 800G link speeds. | 5.6.0 | 5.7.0-5.12.1 |
| 3497622 | When you remove PSUs, then plug them back in, you might experience traffic loss and some ports might be in a down state. | 5.6.0-5.12.1 | |
| 3484058 | When you power on the NVIDIA SN3420 switch with no connected cables, the QSFP ports LEDs light in amber. | 5.3.0-5.8.0 | 5.9.0-5.12.1 |
| 3472163 | On a switch with the Spectrum-4 ASIC, packets that are smaller than 256 bytes are not included in multicast flows. Multicast flows support packets that are 256 bytes or larger. | 5.6.0-5.12.1 | |
| 3463827 | On rare occasions, SPT switchover might not happen cleanly in PIM, resulting in some dropped packets. If you use PIM-SM to replicate EVPN BUM traffic, you might see a brief drop of multicast traffic before recovering due to normal PIM-SM traffic timeout. | 5.6.0-5.8.0 | 5.9.0-5.12.1 |
| 3452732 | The nv set router policy ext-community-list command does not generate the standard based BGP community list. As a result, routes do not match the expected community list. To work around this issue, create a snippet to add the policy configuration to the /etc/frr/frr.conf file, then patch the configuration. For example:cumulus@switch:~$ sudo nano frr_policy.yaml- set: cumulus@switch:~$ nv config patch frr_policy.yaml | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3452681 | When you run the NVUE nv show system aaa tacacs authorization commands to show per command authorization for a specific TACACS+ user privilege level, you see an error message similar to Error: GET /nvue_v1/system/aaa/tacacs/authorization/1?rev=operational responded with 404 NOT FOUND. | 5.5.0-5.10.1 | 5.11.0-5.12.1 |
| 3445841 | FRR does not apply Type-0 ESI configuration for EVPN multihoming bonds consistently after an FRR service reload. This issue occurs because the system MAC address value (es-sys-mac) is only compatible with a 3-byte Ethernet segment ID (es-id) for Type-3 ESIs, but still renders even when the Ethernet segment ID is 10 bytes for Type-0 ESIs. To work around this issue, configure EVPN multihoming bonds with a Type-3 ESI (es-sys-mac plus a 3-byte es-id). | 5.0.0-5.6.0 | 5.7.0-5.12.1 |
| 3444490 | Migration from ONYX to Cumulus Linux is supported and tested with ONYX version 3.10.4302 GA only. | 5.6.0-5.12.1 | |
| 3442569 | When trying to access the NVUE API, user accounts authenticated with a newly-configured external service, such as TACACS, RADIUS, or LDAP, receive a 401 forbidden error. To work around this issue, after enabling a new authentication service, make sure to restart both nginx.service and nvued.service to begin authenticating users against the new authentication service. | 5.5.0-5.12.1 | |
| 3433577 | When you use a single VXLAN device (SVD) with MLAG and static VXLAN tunnels, Cumulus Linux incorrectly associates the MAC addresses it learns from the VXLAN fabric to the bridge PVID. This issue can lead to a feedback loop between the clagd service and switchd, and might result in critical CPU usage with an out of memory condition. Do not use an SVD when enabling MLAG in a static VXLAN environment. | 5.5.0-5.8.0 | 5.9.0-5.12.1 |
| 3430430 | When you configure PTP on 50G ports, the offset correction might be higher, which can affect the time synchronization of the node. To work around this issue, configure PTP on 100G ports, or on 10G or 1G ports with PTP shaper enabled. | 5.5.0-5.12.1 | |
| 3428677 | In certain cases, Cumulus Linux does not process next hop updates because the zebra IP routing manager thinks the state of the next hops is unchanged. As a result, route installation fails and remains in a rejected state. | 5.3.0-5.6.0 | 5.7.0-5.12.1 |
| 3424967 | sudo for TACACS+ users with privilege level 15 does not work when reaching the TACACS+ server through the default VRF. To work around this issue, specify the interface name that the default VRF uses in the vrf= setting of the /etc/tacplus_servers file or run the NVUE nv set system aaa tacacs vrf command. If you don’t run either command, a TACACS+ user with privilege level 15 can run vrf task exec default sudo … to execute the sudo command. | 5.0.0-5.12.1 | |
| 3420056 | The ADVA 5401 SFP module with hardware revision 5.01 does not come up at layer 1 when you use 10G QSA adaptors. To work around this issue, use 25G QSA adaptors. | 4.4.0-4.4.5, 5.0.0-5.12.1 | |
| 3419928 | The NVUE PIM timer command option names keep-alive and rp-keep-alive are inconsistent and need to change to keepalive and rp-keepalive. | 5.4.0-5.6.0 | 5.7.0-5.12.1 |
| 3405024 | You cannot remove PBR map configuration with source and destination rules. To work around this issue, delete the entire PBR map clause. | 5.5.0-5.6.0 | 5.7.0-5.12.1 |
| 3393966 | When you configure OSPF network statements using NVUE with the nv set vrf command, subsequent configuration changes with NVUE might bring down all OSPF neighbors. To work around this issue, create an NVUE snippet to configure the network statement, or use the nv set interface command to enable OSPF on interfaces instead of using a network statement. | 5.5.0-5.9.2 | 5.10.0-5.12.1 |
| 3362113 | If you restore an NVUE startup.yaml file or run the nv config patch command after an upgrade that includes breakout ports with QoS configuration, the NVUE configuration fails to apply. Subsequent attempts to run nv config apply fail with a message similar to Invalid config [rev_id: 11] qos config is not supported on the following invalid interface: swp1s0. Supported on swp and bond interface types. To work around this issue, run nv unset on the configured QoS settings, then apply the breakout port configuration before you configure QoS. Alternatively, you can remove the QoS configuration from the yaml file and patch it separately after applying the breakout configuration. | 5.4.0-5.12.1 | |
| 3347677 | In an MLAG configuration, when a link failure occurs on the peerlink or the peerlink shuts down, the switch in the secondary role attracts traffic to its local VTEP as it advertises the local VTEP IP address momentarily just before the VXLAN device is protodown. This traffic is dropped for a brief moment (between 5 and 10 seconds) because the MLAG bonds on the secondary switch are already protodown. | 5.1.0-5.6.0 | 5.7.0-5.12.1 |
| 3347538 | When connecting NVIDIA-to-NVIDIA in PAM4, you must enable auto-negotiation. | 5.4.0-5.12.1 | |
| 3341214 | If you use the NVUE REST API to configure a local user with a hashed password, the user cannot log in and the /etc/nvue.d/startup.yaml file shows the password as plain text. | 5.4.0-5.12.1 | |
| 3334275 | When you run the sensors command, the output shows an erroneous fault on some front panel ports. | 5.2.0-5.7.0 | 5.8.0-5.12.1 |
| 3329518 | When using TACACS+, if the /etc/nsswitch.conf file specifies passwd: files tacplus (files is listed before tacplus), a user that is present in both the local /etc/passwd file and the TACACS+ server cannot log into the switch. NVIDIA recommends that when using TACACS+, you list tacplus before files in /etc/nsswitch.conf. When using NVUE, ensure that tacacs has priority over local. | 5.4.0-5.12.1 | |
| 3327477 | If you use su to change to a user specified through TACACS+, the user becomes the local tacacs0 thru tacacs15 user instead of the named user to run sudo commands. As a result, the named user password might not match the local tacacs0 thru tacacs15 user password. | 3.7.0-3.7.16, 4.0.0-4.4.5, 5.0.0-5.12.1 | |
| 3326659 | If you have a large number of MAC addresses, they do not age out at the MAC ageing timeout value configured on the switch. It might take up to 30 seconds more for the MAC addresses to age out and be deleted from the hardware. To work around this issue, wait for the ageing timeout value plus 30 seconds. | 5.4.0-5.12.1 | |
| 3266197 | When you disable BGP globally with the nv set router bgp enable off command, applying the configuration with NVUE might fail due to an FRR reload failure. | 5.2.0-5.6.0 | 5.7.0-5.12.1 |
| 3264269 | When you change the BGP router ID that causes a change to an EVPN VNI RD, EVPN EAD-per-EVI routes are not updated properly. | 5.3.0-5.6.0 | 5.7.0-5.12.1 |
| 3258232 | If you use NVUE to configure multiple SNMP listener addresses at the same time, the SNMP service fails to start. To work around this issue, configure multiple SNMP listener addresses one at a time. | 5.3.0-5.6.0 | 5.7.0-5.12.1 |
| 3253218 | Auto-negotiation isn’t supported on Spectrum-2 and Spectrum-3 switches using the 1G SFP-T module; FORCE 1G is configured instead. | 5.4.0-5.12.1 | |
| 3241567 | When you apply switch configuration for the first time on a freshly booted switch and you run the nv config apply command after setting the hostname with nv set system hostname, you might see the error message Failed to start Hostname Service. To work around this issue, run the nv config apply command a second time. | 5.3.0-5.12.1 | |
| 3232091 | The NVUE nv unset interface command does not restore the port lane setting to the default value. To work around this issue, run the nv set interface command. | 5.4.0-5.6.0 | 5.7.0-5.12.1 |
| 3226506 | The l1-show eth0 command does not show port information and is not supported in this release. | 5.3.0-5.12.1 | |
| 3225117 | Occasionally, packet losses might occur on 25G ports when the link is raised without FEC. | 5.4.0-5.12.1 | |
| 3221628 | Cumulus Linux VX images might include an incorrect entry at the end of /etc/apt/sources.list, which produces warnings when you run apt update. Remove this entry to avoid these warnings. | 5.2.0-5.6.0 | 5.7.0-5.12.1 |
| 3172504 | When you connect the NVIDIA SN4600C switch to a Spectrum 1 or Spectrum-3 switch with a 40GbE passive copper cable (Part Number: MC2210126-005) on edge ports 1-4 and 61-64, there is an Effective BER of 1E-12 in PHY. | 5.2.0-5.12.1 | |
| 3147782 | You cannot use NVUE to configure an SNMP view to include a subtree beginning with a period. For example:cumulus@switch:~$ nv set service snmp-server viewname cumulusOnly included .1.3.6.1.4.1.40310Error: GET /nvue_v1/service/snmp-server/viewname/cumulusOnly/included?pointers=%5B%22%2Fparameters%22%2C+%22%2Fpatch%2FrequestBody%2Fcontent%2Fapplication~1json%2Fschema%22%2C+%22%2Fpatch%2Fparameters%22%2C+%22%2Fpatch%2Fresponses%2F200%2Flinks%22%5D responded with 404 NOT FOUNDTo work around this issue, reference the OID without the preceding period ( . ) in the command. | 5.3.0-5.12.1 | |
| 3145869 | On a Spectrum-3 switch, the PTP offset in 10GbE changes between +-27. The average offset is around 7. | 5.2.0-5.12.1 | |
| 3141826 | A slow memory leak (~5KB over 24 hour period at a 60 second polling interval) might occur in SNMP when you walk the following system MIB objects (1.3.6.1.2.1) 1.3.6.1.2.1.47 –> Entity MIB 1.3.6.1.2.1.99 –> Entity Sensor MIB 1.3.6.1.2.1.23 –> rip2 1.3.6.1.2.1.2 –> interface/interfaces 1.3.6.1.2.1.31 –> ifMIB 1.3.6.1.2.1.4 –> IP 1.3.6.1.2.1.25 –> hostResource | 5.0.1-5.8.0 | 5.9.0-5.12.1 |
| 3135952 | PAM4 split cables (such as 2x100G, 4x100G, and 4x50G) do not work with a forced speed setting (when auto-negotiation is off) as the default speed enabled is for NRZ mode (such as 100G_4X). To work around this issue, set the appropriate lanes for forced speed (with auto-negotation off) with the ethtool -s swpX speed <port_speed> autoneg off lanes <no_of_lanes> command. For example:cumulus@switch:~$ sudo ethtool -s swp1 speed 100000 autoneg off lanes 2 | 5.2.0-5.12.1 | |
| 3115242 | When you configure two VNIs in the same VLAN, ifupdown2 shows a vlan added to two or more VXLANS warning, which is only issued after the VNI is already added to the bridge. This leaves the new VNI in the PVID even if there is already an existing VNI configured in that PVID. | 5.1.0-5.12.1 | |
| 3103821 | On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.12.1 | |
| 3084476 | After you disable traffic shaping in the /etc/cumulus/datapath/qos/qos_features.conf file, the default QOS traffic shaping configuration does not restore. To work around this issue, restart switchd. | 4.4.3, 5.0.0-5.12.1 | 4.4.4-4.4.5 |
| 3084027 | Under a high load, you might see ingress drop counters increase. The drops are classified as HwIfInDiscards in ethtool and shown as ingress_general in hardware. | 4.3.0-4.4.5, 5.0.0-5.12.1 | |
| 3071652 | On rare occasions, after you reboot or restart switchd on a Spectrum 1 switch, any 25G connections with Direct Attach Copper (DAC) cables that connect from the switch to a non-NVIDIA device might flap continuously. To work around this issue, bring the affected link administratively down for a few seconds on the non-NVIDIA device, then bring the link back up. | 4.4.4-4.4.5, 5.1.0-5.12.1 | |
| 3061656 | When the CPU load is high during a warm boot, bonds with a slow LACP rate fail to forward layer 2 traffic for up to 60 seconds (depending on the duration of the CPU load) and static bonds fail to forward layer 2 traffic for up to 5 seconds. | 5.1.0-5.12.1 | |
| 2972540 | With RADIUS enabled for user shell authentication, there might be a delay in local user authentication for non cumulus user accounts. | 5.0.0-5.12.1 | |
| 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, 5.0.0-5.12.1 | 3.7.16 |
| 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, 5.0.0-5.12.1 | |
| 2932083 | 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 filesare processed Vulnerable: <= 9.27~dfsg-2+deb10u4Fixed: 9.27~dfsg-2+deb10u5 | 5.0.0-5.12.1 | 4.4.3-4.4.5 |

| 2885305 | Certain Murata PSU attributes show intermittently in the sensors command output. To work around this issue, upgrade to the latest PSU firmware on Murata. | 5.0.0-5.12.1 | |
| 2867042 | When connecting the NVIDIA SN4600 switch to another NVIDIA Spectrum switch, you must use auto-negotiation mode (not force mode); otherwise the switch might use the wrong Tx configuration. | 5.0.0-5.12.1 | |
| 2823307 | Cumuls Linux does not support a bond with more than 64 ports. Any configuration with more than 64 ports in a bond changes all ports to down when you apply the configuration. | 5.0.0-5.12.1 | |
| 2736108 | When you change the VRRP advertisement interval on the master, the master advertisement interval field in the show vrrp command output does not show the updated value. | 4.4.0-4.4.5, 5.0.0-5.12.1 | |
| 2684925 | The NVUE nv show vrf default router bgp peer command produces a 404 not found error. | 4.4.0-4.4.5, 5.0.0-5.12.1 | |
| 2671652 | In VXLAN routing environments, you might experience sub-optimal route convergence delays (longer than five seconds) when a prefix transitions to a new ECMP next-hop group. This condition might occur when a VTEP loses ECMP routes through all uplink peerings, then installs the routes through a different path, such as an MLAG peerlink. | 4.4.0-4.4.5, 5.5.0-5.12.1 | |
| 2543915 | When you enable a service in the management VRF, systemctl issues a warning similar to the following:Warning: The unit file, source configuration file or drop-ins of ntp@mgmt.service changed on disk.

Fixed Issues in 5.6.0
| Issue ID | Description | Affects |
|---|---|---|
| 3715651 | If you run NVUE commands to configure PIM for a VRF before you create the VRF, PIM does not create the pimreg device and the pimd service crashes. | 5.5.1 |
| 3695541 | When applying a full configuration with NVUE that includes VRRP and BGP in VRFs, the VRRP configuration does not come up after you run nv config apply. BGP routes might also be missing. This issue only happens during the initial nv config apply of a full configuration, not during a normal initialization during a reboot or FRR restart. To work around this issue, reboot or restart FRR. | 5.5.1 |
| 3647426 | If BGP remote-as is set to an integer and you try to configure the local-as for a BGP instance, you see the following error:% AS specified for local as is the same as the remote as and this is not allowedThis configuration is not allowed; it is considered to be eBGP and local preference is not advertised. | 4.3.0-4.3.1 |
| 3572580 | You cannot set a VLAN match and a MAC protocol IPv4 match in a MAC type ACL rule. To apply ACLs with a VLAN match and layer 3 header matches ( IPV4/IPV6), you need to use type ipv4 or ipv6 ACLs with the VLAN match specified. | 5.5.1 |
| 3572566 | The NVUE nv action commands are missing from nv list-commands output. | 5.5.1 |
| 3560622 | When you configure a route distinguisher (RD) or a route target (RT) manually for layer 2 VNIs, type-1 routes are not properly updated, type-1 EVI routes with the old RD are not properly withdrawn, and type-1 ES routes do not have the corresponding layer 2 VNI route target updated. | 5.0.0-5.5.1 |
| 3549138 | In an EVPN environment with ARP suppression enabled, when a host sends a unicast ARP request to a remote host, the ARP reply is duplicated. It is replied once by the remote host and once by the VTEP. | 5.5.0-5.5.1 |
| 3541912 | Collecting a cl-support file in a high VNI and interface environment can result in an out-of-memory (OOM) event on the switch. An OOM event can cause critical services to restart and might impact traffic. | 5.1.0-5.5.1 |
| 3541518 | When you remove the update-source configuration for a BGP neighbor, the peering is reset if the neighbor is a member of a peer group with the same update-source configuration. | 5.5.0-5.5.1 |
| 3538497 | In an EVPN symmetric routing configuration, after rebooting a switch that uses VLAN 1 for a layer 3 VNI, traffic forwarding for VLAN 1 fails. To work around this issue, restart the FRR service with the sudo systemctl restart frr.service command. | 5.5.0-5.5.1 |
| 3528359 | A switchd assertion crash occurs after KVD resource exhaustion in the SDK because entries are in a pending delete state, which causes an ECMP allocation failure. | 5.5.0-5.5.1 |
| 3526004 | For layer 3 VNIs, Cumulus Linux automatically creates an SVI name that includes an underscore (for example, vlan4036_l3), which is not allowed in SVI names. As a result, commands such as nv show interface for the SVI show an error. The underscore (_) character is now allowed in SVI names. | 5.5.0-5.5.1 |
| 3520511 | If you apply EVPN multihoming configuration such as es-df-pref, es-id and es-sys-mac with vtysh after you remove a bond interface that is part of a bridge and run ifreload -a, FRR crashes. To work around this issue, do not remove a bond from a bridge before you configure EVPN multihoming with vtysh. | 5.5.1 |
| 3517376 | When you use CMIS specification based optics, the l1-show command output provides incorrect values for digital diagnostics (TX Power and RX Power). To work around this issue, run the mlxlink command with either the -m or –cable –ddm flags. | 5.5.0-5.5.1 |
| 3509445 | If a BGP numbered session is in a non-established state, SNMP walk commands to the system might time out when the BGPVRF MIB is included in the OIDs to collect. In addition, FRR might report warnings about AgentX in the log files. | 5.5.0-5.5.1 |
| 3498939 | In an EVPN environment, VM migration (IP and MAC address migration) might not work because the new local VTEP to which the VM migrates does not install the entry in the kenel. To work around this issue, restart the switchd service. | 5.4.0-5.5.1 |
| 3496931 | When you update a prefix list associated with an RP, the pimd service might crash if the prefix list exists without any prefixes. To work around this issue, ensure that any prefix list associated with an RP includes at least one prefix at all times. | 5.3.1-5.5.1 |
| 3496889 | When PTP is not enabled on the switch, NVUE nv show ptp commands freeze. This might cause other NVUE commands to fail and the NVUE service to restart. | 5.3.1-5.5.1 |
| 3495630 | The NVUE nv show service ptp command output shows an incorrect value. To work around this issue, run the nv show service ptp command or the Linux pmc utility. | 5.3.1-5.5.1 |
| 3491259 | When BGP receives an EVPN type-5 route with a gateway IP overlay attribute, the gateway IP overlay attribute in the attr memory (which is already inserted in the attribute hash) might change. As a result, the modified attr memory might match with another attr in the attribute hash, which produces duplicate entries in the hash table. As a result, BGP might crash when deleting one of the duplicate attr structures. | 5.0.0-5.5.1 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 |
| 3486102 | SNMP and TACACS secrets are shown in cleartext. | 5.5.0-5.5.1 |
| 3482006 | If FRR learns a layer 2 entry against a VNI and you reconfigure the VNI later as a layer 3 VNI, the original layer 2 entry does not clear and remains in the forwarding database. | 5.0.0-5.5.1 |
| 3479786 | The switchd service does not handle certain route and next hop updates, which causes a synchronization loop. For example, in a VRF route leaking configuration, where a next hop group spans across multiple VRFs, when one of the routes is withdrawn and the next hop is no longer used, switchd has problems synchronizing other next hops in the groupTo work around this issue, disable next hop groups in zebra with the vtysh zebra nexthop proto only command, and then reboot the switch. | 5.3.0-5.5.1 |
| 3474427 | On rare occasions, LLDP and other CPU originated IP packets that egress a port might get replicated in the data plane and forwarded out of another port as well. The peer node might discard the unicast packets on the wrong port because of the destination MAC address; however, there might be problems with multicast packets, such as LLDP, which uses a multicast MAC address as the destination MAC address. To work around this issue, reboot the switch. | |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 |
| 3472865 | The json output for the vtysh -c ‘show bgp all json command is missing a string key in front of the list of routes under the l2vpnevpn address family. | 5.4.0-5.5.1 |
| 3471052 | On certain QSFP-DD and OSFP optical modules, the ethtool -m command, and the related NCLU and NVUE commands that display optical module information fail. | 5.4.0-5.5.1 |
| 3470941 | On the NVIDIA SN4700 switch, reversing the upper four lanes on a port does not work and might cause link degradation. If you swap between the upper and lower four lanes on a port, the firmware gets stuck. | 5.3.0-5.5.0 |
| 3467890 | BGP aggregate routers are not advertised after learning the same route from another protocol. To work around this issue, restart the FRR service or, if possible, don’t learn the route from another protocol (use route maps instead). | 5.3.0-5.5.1 |
| 3466703 | In rare cases when there is high load, the clagd service might experience a buffer overflow and MLAG bonds stay in a proto-down state on the secondary switch. You see a “NetlinkThread: Netlink overflow” log message and the MLAG state indicates VLAN conflicts between peers. To work around this issue, restart the clagd service with the sudo systemctl restart clagd command on the switch that reports the overflow log message. | 5.2.0-5.5.1 |
| 3463976 | Multipath routes using next hop objects might end up hashing to an unresolved next hop and drop traffic. | 5.4.0-5.5.1 |
| 3459696 | If you run the NVUE nv show vrf command when the BGP instance is not enabled, you see an NVUE traceback error. | 5.4.0-5.5.1 |
| 3459460 | On certain QSFP-DD and OSFP optical modules, the ethtool -m command, and the related NCLU and NVUE commands that display optical module information fail. | |
| 3455078 | When you bring down or delete a bridge or all interfaces on the switch, you see the following error message in the /var/log/switchd.log file:ERR bridge destroy for vlanThe errors are temporary and have no impact on functionality or traffic. | 5.5.0-5.5.1 |
| 3452763 | When you use the NVUE API with TACACS+, users might see a 403 Forbidden message if no TACACS+ user has logged in some other way, such as with SSH. To work around this issue, log in any TACACS+ user through SSH before you use the NVUE API with TACACS+ users, or run the following commands:cumulus@switch:~$ sudo touch /run/tacacs_client_mapcumulus@switch:~$ sudo chown root:shadow /run/tacacs_client_mapcumulus@switch:~$ sudo chmod 0644 /run/tacacs_client_map | 5.5.0-5.5.1 |
| 3448984 | If you use NVUE to apply a configuration when the optional TACACS+ packages are not installed on the switch, you might see messages similar to the following in the /var/log/syslog file when auditd restarts (for example, when the switch reboots):audispd: Unable to stat /sbin/audisp-tacplus (No such file or directory) audispd: Skipping audisp-tacplus.conf plugin due to errorsThese messages do not affect the functionality of the switch. | 5.5.0-5.5.1 |
| 3447762 | If the NVUE startup.yaml configuration file is invalid, the nv config apply startup command times out without providing details on the error. | 5.4.0-5.5.1 |
| 3444668 | If the SDK becomes stuck and not able to process API calls, the systemd watchdog stops switchd and Cumulus Linux generates a cl-support file. switchd restarts after the watchdog timeout and then runs without issues | |
| 3436595 | When using WJH, if you export dropped packets to a file in PCAP format, the file contains custom WJH header data. As a result, certain tools, such as Wireshark, cannot decode the data. To work around this issue, use the –no_metadata option with the export command:cumulus@switch:~$ what-just-happened poll –export –no_metadata | 5.4.0-5.5.1 |
| 3436305 | Auto-negotiation and link-training is not supported at 25G between the NVIDIA SN5600 switch and non-NVIDIA devices. | |
| 3436296 | On the NVIDIA SN5600 switch, the 8x port breakout is not supported with the MCP4Y10-N00A cable | |
| 3436291 | The NVIDIA SN5600 switch does not support connecting to a Spectrum-2 or Spectrum-3 switch with an MCP7Y70-H001 4X breakout cable. | |
| 3436287 | The NVIDIA SN5600 switch does not support connecting to a Spectrum-1 switch using a 2x breakout with the MCP7Y60-H001 copper cable at 25G. | |
| 3436229 | On the NVIDIA SN5600 switch, when you connect a Service port to non-NVIDIA devices, auto-negotiation is not supported for 25G links. | |
| 3436215 | On the NVIDIA SN5600 switch, the thermal control service crashes when you remove a fan tray. | |
| 3433944 | The wjh_dissector.lua WJH packet decoder script provided with Cumulus Linux might fail to decode all WJH packets. | 5.4.0-5.5.1 |
| 3419940 | When generating a cl-support file either manually or when an issue occurs on the system, you see the following kernel error messages:‘Register access failed (reg_id=0x9029, status=0x4)’ followed by a hex dump of a few linesThis error message is benign and has no functional impact. | 5.5.0-5.5.1 |
| 3413785 | To reach the TACACS+ server through the default VRF, you must specify the egress interface you use in the default VRF. Either run the NVUE nv set system aaa tacacs vrf command (for example, nv set system aaa tacacs vrf swp51) or set the vrf= option in the /etc/tacplus_servers file (for example, vrf=swp51). A similar issue might prevent TACACS+ users with privilege level 15 from using sudo if the TACACS+ server is reachable only on the default VRF. If this occurs, and you do not run the above configuration workaround, the TACACS+ user with privilege level 15 can use vrf task exec default sudo … to execute the sudo command using the TACACS+ server on the default VRF. | 5.0.0-5.5.1 |
| 3394674 | If you restart FRR with the log file debugging level set to informational, BGP crashes. | 5.4.0-5.5.1 |
| 3378733 | After you add or delete a static MAC entry on the bridge FDB, a core dump occurs if the interface is VXLAN and the MAC address is 00:00:00:00:00:00. | 5.4.0-5.5.1 |
| 3344846 | The Spectrum-3 hardware configuration is not optimized for the best PTP accuracy when using 25GbE. You might see higher than expected PTP offsets on this platforms and interface speed. | 5.4.0-5.5.1 |
| 3336808 | If you run the NVUE nv set interface command without providing a description, the nv config apply command fails with the error Unable to restart services (ifreload-nvue.service). | 5.4.0-5.5.1 |
| 3293114 | In Cumulus Linux 5.4 and earlier, the command to enable Neighbor Discovery (ND) router advertisement is inverted and causes confusion; nv set interface . In Cumulus Linux 5.5 and later, the command to enable router advertisement is updated to nv set interface . | 5.3.0-5.5.1 |
| 3187469 | At high scale with 160 VRFs and 10 VLANs per VRF (a total of 1600 VLANs), you see traffic loss during primary switch reboot. To work around this issue, reduce the scale to 40 VRFs with no more than 400 VLANs in the configuration, and use a common MAC address. | 5.1.0-5.5.1 |
| 3178090 | The cl-support generation script causes TC filter collection to run as a background process for each interface, which can lead to memory exhaustion on a high scale configuration and on a switch with a small memory footprint. | 5.1.0-5.5.1 |
| 3172682 | On rare occasions, when you query the system hostname through the hostnamctl application, you see a timeout. NVUE uses the hostnamctl application to determine the system hostname, which can result in an nv config apply command failure. | 5.2.0-5.5.1 |
| 3069069 | When you run the systemctl reload switchd command, there is momentary traffic loss after a port configured with lossless buffers goes down. This is only temporary and the traffic stabilizes after the initial drops. | 5.1.0-5.5.1 |
