Open Issues in 5.3.1
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3576949 | When you run the NVUE nv set service snmp listening-address localhost vrf or nv set service snmp listening-address localhost-v6 vrf command to configure the SNMP listening address, Cumulus Linux applies the listening address to the default VRF instead of the VRF you specify. | 5.3.0-5.6.0 | |
| 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 | |
| 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 | |
| 3562767 | ACLs do not process inbound DHCP packets and the packets do not contribute to ACL counters | 5.2.0-5.5.1 | 5.6.0 |
| 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manually for layer 2 VNIs, type-1 routes are not properly updated, type-1 EVI routes with the old RD are not properly withdrawn, and type-1 ES routes do not have the corresponding layer 2 VNI route target updated. | 5.0.0-5.6.0 | |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 | 5.6.0 |
| 3484058 | When you power on the NVIDIA SN3420 switch with no connected cables, the QSFP ports LEDs light in amber. | 5.3.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.6.0 |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 | 5.6.0 |
| 3470941 None | On the NVIDIA SN4700 switch, reversing the upper four lanes on a port does not work and might cause link degradation. If you swap the upper and lower four lanes on a port, the firmware gets stuck. | 5.3.0-5.5.0 | 5.5.1-5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | |
| 3434791 | Changing the ebgp-multihop setting for a BGP peer always resets the peer, even if the configured TTL value matches the existing TTL value of the peer. | 5.3.1-5.4.0 | 5.5.0-5.6.0 |
| 3432897 | When you remove the restriction from a TACACS+ mapped user to remove per command authorization, the tacplus-restrict -R command does not restore ownership of restored files correctly. As a result, some commands might fail due to permission errors in the files or directories under the home directory. To work around this issue, run the sudo chown command to correct the ownership of the affected files and directories. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3429530 | On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.6.0 |
| 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 | |
| 3424967 | sudo for TACACS+ users with privilege level 15 does not work when the TACACS+ server is to be reached through the default VRF (with vrf=default set in the /etc/tacplus_servers file). 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 using the TACACS+ server on the default VRF. | 5.0.0-5.6.0 | |
| 3413827 None | During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.6.0 |
| 3402935 None | For layer 3 interfaces configured on the switch, certain triggers, such as port flaps and subinterface flaps, or when configuring the ports to and from layer 2 and layer 3, cause the dummy internal VLAN to not free up, which can result in exhaustion of the dummy internal VLANs designated for the layer 3 interfaces. When this occurs, you see the following switchd log messages:ERR dummy internal vlans exhaustedERR cannot allocate vlan for sub-interface | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3393306 | The python-netaddr package is not preinstalled on the switch, which leads to an error similar to the following when SNMP accesses data from the CUMULUS-BGPVRF-MIBCUMULUS-BGPVRF-MIB::bgpPeerFsmEstablishedTransitions = No Such Instance currently exists at this OIDTo work around this issue, manually install the python-netaddr package with the sudo -E apt-get install python-netaddr command. | 5.3.1-5.4.0 | 5.5.0-5.6.0 |
| 3390758 | The neighmgrd service does not enable the snooper unless ARP suppression is enabled on at least one VXLAN interface. This can result in missing ARP and NDP entries if the host does not directly interact with the switch. | 5.3.1-5.4.0 | 5.5.0-5.6.0 |
| 3389198 | The NVUE nv unset command does not completely remove IPv6 DNS server configuration | 5.3.1-5.4.0 | 5.5.0-5.6.0 |
| 3388067 | TACACS+ packages in the local apt repository might be out of date; as a result, the upgrade does not install tacacs0 through tacacs15 users in the correct NVUE groups. When you run NVUE commands as a TACACS+ user, the commands fail and you see the error You do not have permission to execute that commandTo obtain the correct packages, install the tacplus-client package and its dependencies from apt.cumulusnetworks.com. | 5.1.0-5.4.0 | 5.5.0-5.6.0 |
| 3379873 | apt source linux fails to download the Linux kernel source code. To work around this issue, run the sudo apt update && sudo apt install linux-source-5.10 command or download the desired version from https://apt.cumulusnetworks.com/repo/pool/cumulus/l/linux/ and install it with the sudo dpkg -i $filename command. The source code in a tar.xz file will then be located in the /usr/src/ directory. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 3368217 None | When daylight saving time changes, the MLAG initDelay timer resets and all MLAG bonds go down. | 4.4.4-4.4.5, 5.2.1-5.6.0 | |
| 3351953 | In rare circumstances, attempting to install a Cumulus Linux 5.3 image can fail during installation. The device stops at the (initramfs) prompt. To resume installation, enter the exit command at the (initramfs) prompt. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3351951 None | Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-5.3.1 | 5.4.0-5.6.0 |
| 3351936 | Switch fans run at very high speed but the temperature is normal. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3350789 | NVUE deprecated the port split command options (2x10G, 2x25G, 2x40G, 2x50G, 2x100G, 2x200G, 4x10G, 4x25G, 4x50G, 4x100G, 8x50G) with no backwards compatibility. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3349207 | The switch does not learn MAC addresses from DHCP packets. When a DHCP enabled host is plugged in for the first time, it tries to obtain an IP address through DHCP. The switch does not learn the MAC address of the host when it receives these DHCP packets; therefore, the host MAC address is not updated in the local forwarding database and it does not get advertised across EVPN. The switch learns the MAC address when it receives other packets, such as ARP or ND from the host. To work around this issue, either configure a temporary IP address on the host to initiate ARP/ND or enable IPv6, which sends ND after link local address creation. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | |
| 3340890 | When you run the NVUE nv show interface command, you see an error similar to the following:Error: GET /nvue_v1/interface/swp45?rev=operational responded with 500 INTERNAL SERVER ERROR | 5.3.0-5.4.0 | 5.5.0-5.6.0 |
| 3339336 | The ethtool -m command does not show Digital Optical Monitoring (DOM) for SFP transceivers. To work around this issue, run the l1-show or mlxlink command instead. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3334275 | The sensors.conf files in Cumulus Linux are out of date. | 5.2.0-5.5.1 | 5.6.0 |
| 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 |
| 3330600 | The SNMP monitor might fail to send the expected traps. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3329494 | Ethtool HwIfInDot3FrameErrors (Rx FCS Errors) might lead to an incorrect and very large HwIfInErrors count. To work around this issue, stop the source of the FCS errors, then reset the interface counters. First, run the sudo mst status command to find the device, then run the sudo mlxlink -d command to reset the interface counters; for example, sudo mlxlink -d /dev/mst/mt53104_pciconf0 -p 39 -pc. | 5.3.1-5.4.0 | 5.5.0-5.6.0 |
| 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 | |
| 3322944 | The ptmd service causes memory leaks. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3308248 | DHCP packets do not forward over VXLAN interfaces in multicast replication environments. This issue does not affect VXLAN environments using head end replication (HER). | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3303084 | The memory consumption in ptmd can grow when the socket being used for a BFD session needs to be recreated. This is often seen when the route being used to forward the BFD packets is removed; for example, if the connected route is removed when an interface goes down, over which a single hop BFD session is formed. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3301988 | Some EVPN multihoming show commands might cause BGP to crash if you use the json flag and attempt to reference the default VRF by name. For example, show bgp l2vpn evpn es-vrf json. | 5.0.0-5.3.1 | 5.4.0-5.6.0 |
| 3301950 | When upgrading from Cumulus Linux 5.0.0 thru 5.2.1 to Cumulus Linux 5.3.0 or 5.3.1, the babeltrace and python3-babeltrace packages are not added automatically even though they are in the default image in Cumulus Linux 5.3.0 and later. You may need these packages to decode LTTNG traces with /usr/lib/frr/frr_babeltrace.py.. If you need to use this script, run the sudo apt update && sudo apt install babeltrace python3-babeltrace command to install the packages. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3298616 | NVUE gracefully detects and handles upgrades that include valid flexible snippets. For any invalid (incompatible) flexible snippets, you must delete the snippets before you apt upgrade Cumulus Linux; otherwise, the NVUE nv config apply command and the equivalent REST API, do not run. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3296715 | When you clear interface counters with the ethtool -S command, the command fails with the following message:switch:~$ ethtool -S swp1 clearethtool (-S): unknown parameter ‘clear’ | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3293039 | When you add the /etc/frr/frr.conf file to the ignore list for NVUE, any configuration change causes FRR to restart because a check is done to see if any running configuration has changed since the previously applied configuration in the vtysh shell. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3292773 | NVUE requires the SNMPv2 community string to be a minimum of eight characters. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3289972 None | When the switch needs to forward a frame that has a source MAC address of 00:00:00:00:00:00, the dmesg log might report the message bridge: RTM_NEWNEIGH with invalid ether address in a loop every 30 seconds. The log message is harmless and frames with that MAC forward correctly. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3289646 | The memory consumption in ptmd can grow when the socket being used for a BFD session needs to be recreated. This is often seen when the route being used to forward BFD packets is removed; for example, if the connected route is removed when an interface goes down, over which a single hop BFD session is formed. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3283598 None | After you restart the FRR service, show commands incorrectly reflect the VLAN associated with layer 3 VNIs as 0:# net show evpn vni 123VNI: 123Type: L3Tenant VRF: BLUEVlan: 0 | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3267328 | On Spectrum 1 switches when configuring ACLs in non-atomic mode, if there are too many IPv6 matches due to rules with both input-interface and output-interface matches on SVIs, the ACL install fails and switchd crashes. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3266050 | Due to a race at the initial configuration, the SDK RDQ test may test RDQ configured for WJH and fail the test resulting in a fatal health event. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 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 | |
| 3255899 | The Linux utility that sends ARP packets is constrained to 512 interfaces on the system. In large scale deployments, the warm boot process fails repeatedly as it sends gratuitous ARP requests for each local address. This issue does not impact the functionality and can be ignored. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3244955 | ACL configurations fail when the TCAM memory is exhausted because the CTCAM profile is configured with duplicate entries. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3241567 | When you apply switch configuration for the first time on a freshly booted switch, you might see the error message Failed to start Hostname Service when you run the nv config apply command after setting the hostname with nv set system hostname. To work around this issue, run the nv config apply command a second time. | 5.3.0-5.6.0 | |
| 3241047 | When you delete a route under the following conditions, switchd might crash:- The minimum number of routes is set to a non-zero value- KVD utilization is higher than sixty percent - The number of routes currently configured is less than the minimum reserved value, and multiple KVD linear resources have just been freed and are waiting in the Garbage Collector queue. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3234814 | With double tagged QinQ interfaces, if the bridge corresponding to the QinQ interface flaps, you might see invalid learning notifications and errors from similar to the following:Can’t set non-static MAC address for non-vPort 0x0001006B when VID is VFID. | 5.3.0-5.4.0 | 5.5.0-5.6.0 |
| 3226525 | When using TACACS+, if you configure per-command authorization with the tacplus-restrict command, NVUE configuration commands fail for any user with a privilege level lower than 15. This occurs because NVUE is not able to create a .local user directory. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3226506 | The l1-show eth0 command does not show port information and is not supported in this release. | 5.3.0-5.6.0 | |
| 3221628 | Cumulus Linux 5.2.0 and 5.2.1 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 | |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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. | 5.2.0-5.6.0 | |
| 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. | 5.3.0-5.6.0 | |
| 3145869 | On a Spectrum-3 switch, the PTP offset in 10GbE changes between +-27. The average offset is around 7. | 5.2.0-5.6.0 | |
| 3145222 | The NVUE nv show system forwarding –output json command does not provide any output. To work around this issue, run the nv show system forwarding command. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3145204 | On the NVIDIA Spectrum-1 switch, the nv show system forwarding command shows GTP hashing output, which is not supported on this switch. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 3144740 | The /var/lib/snmp/snmpd.conf file contains multiple Warning: Unknown token: ifXTable messages. To avoid these warnings, add the -noTokenWarnings option to the SNMPDOPTS variable in the /etc/defaults/snmpd file, then restart the snmpd service. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 3142615 | The BGP4-MIB.txt file is missing from Net-SNMP agent. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.0.1-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.2.0-5.6.0 | |
| 3122301 | On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.6.0 | |
| 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. | 5.1.0-5.6.0 | |
| 3103821 | On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.6.0 | |
| 3084476 | The default QOS traffic shaping configuration does not restore after you disable traffic shaping in the /etc/cumulus/datapath/qos/qos_features.conf file. To work around this issue, restart switchd. | 4.4.3, 5.0.0-5.6.0 | 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, 5.0.0-5.6.0 | |
| 3074390 | You can not apply NVUE configurations when TACACS is enabled for user authentication. To work around this issue, add the nvue account to the exclude_users line in /etc/tacplus_nss.conf:exclude_users=root,daemon,nobody,cron,radius_user,radius_priv_user,sshd,cumulus,quagga,frr,nvue,snmp,www-data,ntp,man,_lldpd,* | 5.0.1-5.3.1 | 5.4.0-5.6.0 |
| 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, 5.1.0-5.6.0 | |
| 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 | 5.6.0 |
| 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. | 5.1.0-5.6.0 | |
| 3055283 | After you run Linux commands to enable a custom ECMP or LAG hash parameter, if you set the hash_config.enable or lag_hash_config.enable parameter to false, the custom parameters do not restore their default values. To work around this issue, change the custom ECMP or LAG hash parameters to their default values manually. | 5.1.0-5.4.0 | 5.5.0-5.6.0 |
| 3053094 | 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. | 5.1.0-5.6.0 | |
| 3045310 | If GTP Hashing is set to true, after more than two warm boots, switchd fails and a cl-support file is generated. | 5.1.0-5.4.0 | 5.5.0-5.6.0 |
| 3037824 | The NVUE nv show interface command shows an empty table instead of showing the port link state. | 5.0.0-5.3.1 | 5.4.0-5.6.0 |
| 3034435 | In an MLAG EVPN deployment when either of the MLAG peers reboots, FRR incorrectly programs the local host entries in the ARP table as remote. To work around this issue, either restart FRR or use BGP policies to mark and drop routes within an MLAG pair. Both MLAG peers must have an outbound policy that add a community representing the unique MLAG pair to Type-2 EVPN routes and an inbound policy to match and drop that community. | 4.4.4-5.4.0 | 5.5.0-5.6.0 |
| 3015393 | The NVUE nv show interface command shows the operational state of the tunnel as down even though the tunnel is up, and encapsulation and decapsulation occurs correctly. | 5.1.0-5.3.1 | 5.4.0-5.6.0 |
| 2972540 | With RADIUS enabled for user shell authentication, there might be a delay in local user authentication for non cumulus user accounts. | 5.0.0-5.6.0 | |
| 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 |
| 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 | |
| 2904450 | When you run the ethtool -m or the l1-show command, the 400G interface optical values do not show. | 4.4.0-4.4.5, 5.0.0-5.6.0 | |
| 2891255 | CVE-2021-39925: Buffer overflow in the Bluetooth SDP dissector in Wireshark 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17 allows denial of service via packet injection or crafted capture file Vulnerable: <= 2.6.20-0+deb10u1Fixed: 2.6.20-0+deb10u2 | 4.0.0-4.4.1, 5.0.0-5.6.0 | 4.4.2-4.4.5 |

| 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. | 5.0.0-5.6.0 | |
| 2847919 | Configuring a router with the REST API through the switch front panel ports (swps) is supported in the default VRF only. To work around this issue, use the localHost IP address or the MGMT IP address to configure router using the Rest API. | 5.0.0-5.6.0 | |
| 2847755 | When you use NCLU to remove the configuration for a peer that is a member of a group but also has other peer-specific configuration, you must remove the peer-specific configuration before you delete the peer in a separate NCLU commit. | 5.0.0-5.6.0 | |
| 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. | 5.0.0-5.6.0 | |
| 2821929 | FRR restarts even when the NVUE configuration overwrite mode is set. | 5.0.0-5.3.1 | 5.4.0-5.6.0 |

Run ‘systemctl daemon-reload’ to reload unitYou can safely ignore this warning. | 4.0.0-4.4.5, 5.0.0-5.6.0 |
Fixed Issues in 5.3.1
| Issue ID | Description | Affects |
|---|---|---|
| 3303372 | On Spectrum-2 switches, 200G ports might flap. This issue happens rarely. | 5.3.0 |
| 3303082 | When you delete a route under the following conditions, switchd might crash:- The minimum number of routes is set to a non-zero value. - KVD utilization is higher than sixty percent. - The number of routes currently configured is less than the minimum reserved value, and multiple KVD linear resources have just been freed and are waiting in the Garbage Collector queue. | 5.2.0-5.3.0 |
5.3.0 Release Notes
Open Issues in 5.3.0
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 3576949 | When you run the NVUE nv set service snmp listening-address localhost vrf or nv set service snmp listening-address localhost-v6 vrf command to configure the SNMP listening address, Cumulus Linux applies the listening address to the default VRF instead of the VRF you specify. | 5.3.0-5.6.0 | |
| 3562767 | ACLs do not process inbound DHCP packets and the packets do not contribute to ACL counters | 5.2.0-5.5.1 | 5.6.0 |
| 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. | 5.0.0-5.6.0 | |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 3488136 | When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. | 4.2.1-5.5.1 | 5.6.0 |
| 3484058 | When you power on the NVIDIA SN3420 switch with no connected cables, the QSFP ports LEDs light in amber. | 5.3.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.6.0 |
| 3474391 | The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. | 4.3.1-5.5.1 | 5.6.0 |
| 3470941 None | On the NVIDIA SN4700 switch, reversing the upper four lanes on a port does not work and might cause link degradation. If you swap the upper and lower four lanes on a port, the firmware gets stuck. | 5.3.0-5.5.0 | 5.5.1-5.6.0 |
| 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 | 5.6.0 |
| 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 | 5.6.0 |
| 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 | |
| 3432897 | When you remove the restriction from a TACACS+ mapped user to remove per command authorization, the tacplus-restrict -R command does not restore ownership of restored files correctly. As a result, some commands might fail due to permission errors in the files or directories under the home directory. To work around this issue, run the sudo chown command to correct the ownership of the affected files and directories. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3429530 | On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.6.0 |
| 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 | |
| 3424967 | sudo for TACACS+ users with privilege level 15 does not work when the TACACS+ server is to be reached through the default VRF (with vrf=default set in the /etc/tacplus_servers file). 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 using the TACACS+ server on the default VRF. | 5.0.0-5.6.0 | |
| 3413827 None | During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | 5.6.0 |
| 3402935 None | For layer 3 interfaces configured on the switch, certain triggers, such as port flaps and subinterface flaps, or when configuring the ports to and from layer 2 and layer 3, cause the dummy internal VLAN to not free up, which can result in exhaustion of the dummy internal VLANs designated for the layer 3 interfaces. When this occurs, you see the following switchd log messages:ERR dummy internal vlans exhaustedERR cannot allocate vlan for sub-interface | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3388067 | TACACS+ packages in the local apt repository might be out of date; as a result, the upgrade does not install tacacs0 through tacacs15 users in the correct NVUE groups. When you run NVUE commands as a TACACS+ user, the commands fail and you see the error You do not have permission to execute that commandTo obtain the correct packages, install the tacplus-client package and its dependencies from apt.cumulusnetworks.com. | 5.1.0-5.4.0 | 5.5.0-5.6.0 |
| 3379873 | apt source linux fails to download the Linux kernel source code. To work around this issue, run the sudo apt update && sudo apt install linux-source-5.10 command or download the desired version from https://apt.cumulusnetworks.com/repo/pool/cumulus/l/linux/ and install it with the sudo dpkg -i $filename command. The source code in a tar.xz file will then be located in the /usr/src/ directory. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 3368217 None | When daylight saving time changes, the MLAG initDelay timer resets and all MLAG bonds go down. | 4.4.4-4.4.5, 5.2.1-5.6.0 | |
| 3351953 | In rare circumstances, attempting to install a Cumulus Linux 5.3 image can fail during installation. The device stops at the (initramfs) prompt. To resume installation, enter the exit command at the (initramfs) prompt. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3351951 None | Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-5.3.1 | 5.4.0-5.6.0 |
| 3351936 | Switch fans run at very high speed but the temperature is normal. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3350789 | NVUE deprecated the port split command options (2x10G, 2x25G, 2x40G, 2x50G, 2x100G, 2x200G, 4x10G, 4x25G, 4x50G, 4x100G, 8x50G) with no backwards compatibility. | 5.0.0-5.4.0 | 5.5.0-5.6.0 |
| 3349207 | The switch does not learn MAC addresses from DHCP packets. When a DHCP enabled host is plugged in for the first time, it tries to obtain an IP address through DHCP. The switch does not learn the MAC address of the host when it receives these DHCP packets; therefore, the host MAC address is not updated in the local forwarding database and it does not get advertised across EVPN. The switch learns the MAC address when it receives other packets, such as ARP or ND from the host. To work around this issue, either configure a temporary IP address on the host to initiate ARP/ND or enable IPv6, which sends ND after link local address creation. | 5.2.0-5.4.0 | 5.5.0-5.6.0 |
| 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 | |
| 3340890 | When you run the NVUE nv show interface command, you see an error similar to the following:Error: GET /nvue_v1/interface/swp45?rev=operational responded with 500 INTERNAL SERVER ERROR | 5.3.0-5.4.0 | 5.5.0-5.6.0 |
| 3339336 | The ethtool -m command does not show Digital Optical Monitoring (DOM) for SFP transceivers. To work around this issue, run the l1-show or mlxlink command instead. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3334275 | The sensors.conf files in Cumulus Linux are out of date. | 5.2.0-5.5.1 | 5.6.0 |
| 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 |
| 3330600 | The SNMP monitor might fail to send the expected traps. | 5.3.0-5.3.1 | 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 | |
| 3322944 | The ptmd service causes memory leaks. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3308248 | DHCP packets do not forward over VXLAN interfaces in multicast replication environments. This issue does not affect VXLAN environments using head end replication (HER). | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3303372 | On Spectrum-2 switches, 200G ports might flap. This issue happens rarely. | 5.3.0 | 5.3.1-5.6.0 |
| 3303084 | The memory consumption in ptmd can grow when the socket being used for a BFD session needs to be recreated. This is often seen when the route being used to forward the BFD packets is removed; for example, if the connected route is removed when an interface goes down, over which a single hop BFD session is formed. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3303082 | When you delete a route under the following conditions, switchd might crash:- The minimum number of routes is set to a non-zero value. - KVD utilization is higher than sixty percent. - The number of routes currently configured is less than the minimum reserved value, and multiple KVD linear resources have just been freed and are waiting in the Garbage Collector queue. | 5.2.0-5.3.0 | 5.3.1-5.6.0 |
| 3301988 | Some EVPN multihoming show commands might cause BGP to crash if you use the json flag and attempt to reference the default VRF by name. For example, show bgp l2vpn evpn es-vrf json. | 5.0.0-5.3.1 | 5.4.0-5.6.0 |
| 3301950 | When upgrading from Cumulus Linux 5.0.0 thru 5.2.1 to Cumulus Linux 5.3.0 or 5.3.1, the babeltrace and python3-babeltrace packages are not added automatically even though they are in the default image in Cumulus Linux 5.3.0 and later. You may need these packages to decode LTTNG traces with /usr/lib/frr/frr_babeltrace.py.. If you need to use this script, run the sudo apt update && sudo apt install babeltrace python3-babeltrace command to install the packages. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3298616 | NVUE gracefully detects and handles upgrades that include valid flexible snippets. For any invalid (incompatible) flexible snippets, you must delete the snippets before you apt upgrade Cumulus Linux; otherwise, the NVUE nv config apply command and the equivalent REST API, do not run. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3296715 | When you clear interface counters with the ethtool -S command, the command fails with the following message:switch:~$ ethtool -S swp1 clearethtool (-S): unknown parameter ‘clear’ | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3293039 | When you add the /etc/frr/frr.conf file to the ignore list for NVUE, any configuration change causes FRR to restart because a check is done to see if any running configuration has changed since the previously applied configuration in the vtysh shell. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3292773 | NVUE requires the SNMPv2 community string to be a minimum of eight characters. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3289972 None | When the switch needs to forward a frame that has a source MAC address of 00:00:00:00:00:00, the dmesg log might report the message bridge: RTM_NEWNEIGH with invalid ether address in a loop every 30 seconds. The log message is harmless and frames with that MAC forward correctly. | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3289646 | The memory consumption in ptmd can grow when the socket being used for a BFD session needs to be recreated. This is often seen when the route being used to forward BFD packets is removed; for example, if the connected route is removed when an interface goes down, over which a single hop BFD session is formed. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3283598 None | After you restart the FRR service, show commands incorrectly reflect the VLAN associated with layer 3 VNIs as 0:# net show evpn vni 123VNI: 123Type: L3Tenant VRF: BLUEVlan: 0 | 5.3.0-5.3.1 | 5.4.0-5.6.0 |
| 3267328 | On Spectrum 1 switches when configuring ACLs in non-atomic mode, if there are too many IPv6 matches due to rules with both input-interface and output-interface matches on SVIs, the ACL install fails and switchd crashes. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3266050 | Due to a race at the initial configuration, the SDK RDQ test may test RDQ configured for WJH and fail the test resulting in a fatal health event. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 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 | |
| 3255899 | The Linux utility that sends ARP packets is constrained to 512 interfaces on the system. In large scale deployments, the warm boot process fails repeatedly as it sends gratuitous ARP requests for each local address. This issue does not impact the functionality and can be ignored. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3244955 | ACL configurations fail when the TCAM memory is exhausted because the CTCAM profile is configured with duplicate entries. | 5.2.0-5.3.1 | 5.4.0-5.6.0 |
| 3241567 | When you apply switch configuration for the first time on a freshly booted switch, you might see the error message Failed to start Hostname Service when you run the nv config apply command after setting the hostname with nv set system hostname. To work around this issue, run the nv config apply command a second time. | 5.3.0-5.6.0 | |

|---|---|---|
| 3255948 | When you upgrade from Cumulus Linux 5.0.0-5.1.0 to Cumulus Linux 5.2.0 or 5.2.1, warm or fast boot fails. Use regular reboot or csmgrctl -c in this case. | 5.2.0-5.2.1 |
| 3235368 | When you try to configure VRF route leaking between many VRFs using multiple NCLU commands before running the net commit command, the commit fails. To work around this issue, configure VRF leaking one command at a time and run net commit after each command. | 4.4.4-5.2.1 |
| 3231330 None | If BGP neighbor is set, negating with no no neighbor does not disable the setting. To work around this issue and disable the setting, restart the FRR service. | 4.2.1-5.2.1 |
| 3228856 None | If you have a lot of inbound route maps that match lists with many regex statements, a large number of updates from the peer can cause the system to run out of memory. To work around this issue, reduce the number of regex matches in inbound route maps. | 4.4.0-5.2.1 |
| 3228690 | When you configure a routing policy multiple times in NVUE with a match evpn default-route statement, the bgpd daemon terminates. | |
| 3227905 | PTP forced master mode does not work. To work around this issue, change masterOnly to serverOnly in the /etc/ptp4l.conf file. | 5.2.0-5.2.1 |
| 3227895 | The match evpn default-route setting does not filter the default route correctly. | |
| 3227677 | When daylight saving time changes the time, the MLAG initDelay timer resets and all MLAG bonds go down. | 4.4.4-5.2.1 |
| 3227651 None | Docker commands can cause Cumulus Linux commands to fail. apt upgrade can also fail if you use Docker commands implicitly. To work around this issue, run ulimit -v unlimited before running Docker commands or running apt upgrade. | 5.2.0-5.2.1 |
| 3218207 None | Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 |
| 3217675 | When you run the NVUE nv set bridge domain br_default multicast snooping enable off command to disable multicast snooping, the bridge still shows that multicast snooping is enabled. | 5.0.1-5.2.1 |
| 3217674 | Multicast PTP over UDP traffic does not forward to data ports when the PTP service is disabled. To work around this issue, change the ptp.timestamping setting to FALSE in the /etc/cumulus/switchd.conf file, then restart switchd. | 5.0.1-5.2.1 |
| 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 |
| 3211114 | After an abrupt power cycle, the nvued service might fail to start due to NVUE internal data corruptionThis issue has been resolved with the addition of an automatic backup feature, which is enabled by default; if NVUE detects an internal data store corruption, the nvued service recovers from the backup. | 5.2.0-5.2.1 |
| 3211054 | On the NVIDIA Spectrum-2 switch, when receiving multicast traffic on a PIM enabled VLAN, the multicast traffic is forwarded correctly to the associated VLAN, however WJH shows traffic loss with the error:

| 3176318 | The NVUE nv set bridge domain br_default stp priority command does not change the STP priority. | 5.1.0-5.2.1 |
| 3171316 | Various FRR show commands do not have json output. This applies to BGP show commands ending in prefix-list, route-map, dampening parameters, and longer-prefixes. FRR show bgp detail output contains a summary instead of details on each prefix. FRR show bgp … neighbor routes and show bgp … neighbor received-routes both incorrectly use a json key of advertisedRoutes. | 5.2.0-5.2.1 |
| 3166746 | FRR does not install EVPN type-2 routes correctly after the specific operation that deletes and adds all non-uplink ports. The routes show as rejected in the zebra RIB. To work around this problem, restart FRR with the sudo systemctl restart frr command. | 5.1.0-5.2.1 |
| 3159756 | When adding a member port to a bond you sometimes see an error. The error occurs if you configure a port as double tagged, then you remove the double tagged configuration and add the port as a bond member. You might not see the error as it depends on timing of interface events during double tagged interface creation. To work around this issue, remove the bond configuration and add it back again. | 5.2.0-5.2.1 |
| 3157711 | If you disable SNMP with the NVUE command nv unset service snmp-server, the FRR service restarts and removes the cleanup agentx functionality, which is used to obtain FRR MIBs. | 5.2.0-5.2.1 |
| 3150317 | During a host failure, where a link remains up but LACP stops being sent, the EVPN multihoming ES bond goes into bypass mode active without a link state change. | 4.4.2-5.2.1 |
| 3150208 | When a ZTP script executes a switchd restart, the switchd service might fail with the following log message:switchd[11549]: hal.c:1378 CRIT No backends foundTo work around this issue, avoid restarting the switchd service in the ZTP script; reboot the switch instead. | 5.1.0-5.2.1 |
| 3139364 | When Cumulus Linux updates the ECMP container with a new next hop list, it allocates the flow counters for the new next hop list without deallocating the counters bound to the old next hop list. This results in resource exhaustion and you see the following error messages in the /var/log/switchd.log file:hal_mlx_stat.c:3215 ERR Failed to allocate counter(s) for ecmp [71025:0] status: Internal Errorhal_mlx_stat.c:3196 ERR Counter set for ecmp [71025:0] idx 0 failed: Internal Errorhal_mlx_sdk_nexthop_wrap.c:1076 ERR Counter 0 alloc for ecmp next hop failed: Internal Errorhal_mlx_sdk_counter_wrap.c:54 ERR Counter alloc failed: No More ResourcesThis issue does not have any functional impact to forwarding. Even without the flow counters attached to the ECMP group, packet forwarding works without any issues To avoid allocating next hop counters for any new ECMP next hop list update, set mlx.stats.ecmp.enable to FALSE in the /etc/mlx/datapath/stats.conf file, then restart switchd with the sudo systemctl reload switchd command. | 5.0.0-5.2.1 |
| 3139164 | NVUE does not allow you to set 2X/4X lanes. To work around this issue, set the appropriate lanes for forced speed with the ethtool -s swpX speed <port_speed> autoneg off lanes <no_of_lanes> command. For example, ethtool -s swp1 speed 100000 autoneg off lanes 2. | 5.2.0-5.2.1 |
| 3138057 | When the next hop interface for EVPN type 5 routes flaps, FRR might uninstall the routes and Route install failed appears in /var/log/frr/frr.log. To work around this problem, restart FRR with the sudo systemctl restart frr command. | 4.4.0-5.2.1 |
| 3135714 | The tacplus package does not create the correct tacacs0-15 users in the right groups.
