Open Issues in 5.0.1
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4037015 |
The NVUE commands to delete SNMP users, and change authentication passwords and encryption passphrases are not successful. | 4.3.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
| 3980941 |
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 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
| 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, 5.0.0-5.11.0 | |
| 3684998 |
DHCP lease information is not collected in the cl-support file. |
4.3.0-5.6.0 | 5.7.0-5.11.0 |
| 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. |
5.0.0-5.5.1 | 4.3.2-4.4.5, 5.6.0-5.11.0 |
| 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 | 5.7.0-5.11.0 |
| 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manually for layer 2 VNIs, type-1 routes are not properly updated, type-1 EVI routes with the old RD are not properly withdrawn, and type-1 ES routes do not have the corresponding layer 2 VNI route target updated. | 5.0.0-5.5.1 | 5.6.0-5.11.0 |
| 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 4.3.2, the /usr/bin/ssh-agent program has all permissions turned off (chmod 0) to prevent its execution if a vulnerable version is detected. |
4.0.0-4.3.1, 5.0.0-5.11.0 | 4.3.2-4.4.5 |
| 3488136 |
When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. |
4.2.1-5.5.1 | 5.6.0-5.11.0 |
| 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 | 5.6.0-5.11.0 |
| 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 | 5.7.0-5.11.0 |
| 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 | 5.5.0-5.11.0 |
| 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 | 5.5.0-5.11.0 |
| 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. |
5.0.0-5.11.0 | |
| 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, 5.0.0-5.11.0 | |
| 3413827 |
During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. |
4.2.1-4.3.1, 4.4.0-5.4.0 | 4.3.2, 5.5.0-5.11.0 |
| 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 | 5.6.0-5.11.0 |
| 3402935 |
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 | 5.5.0-5.11.0 |
| 3351951 |
Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-4.3.1, 4.4.0-5.3.1 | 4.3.2, 5.4.0-5.11.0 |
| 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 | 5.5.0-5.11.0 |
| 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 | 5.4.0-5.11.0 |
| 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, 5.0.0-5.11.0 | |
| 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 | 5.4.0-5.11.0 |
| 3270988 |
After restarting switchd on the NVIDIA SN2100 switch, the FAN speeds are at one hundred percent. To work around this issue, restart the hw-management service. |
4.4.5-5.2.0 | 5.2.1-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3228899 |
If two FDB entries are added in hardware with a single API call (at the same time), when one entry already exists in hardware and the additional entry has a tunnel type, the resulting FDB entry might be configured improperly in hardware. This can cause corruption of the packets that match the FDB entry. | 4.4.0-4.4.2, 5.0.0-5.0.1 | 4.4.3-4.4.5, 5.1.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3218207 |
Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 | 5.3.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3216922 |
RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users). |
3.7.0-5.2.1 | 5.3.0-5.11.0 |
| 3211359 |
The net show interface command output shows Type=Unknown for the specified interface. |
4.4.3-5.0.1 | 5.1.0-5.11.0 |
| 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:
|
4.4.2-5.2.1 | 5.3.0-5.11.0 |
| 3202991 |
Locally generated multicast traffic including IGMPv2 GSQs do not transmit to local clients when using PIM. | 5.0.1-5.2.1 | 5.3.0-5.11.0 |
| 3200373 |
After rebooting the switch, the IPv6 link local address for an SVI that belongs to non-default VRF is missing, and doesn’t show on the switch. To resolve this issue, run the ifreload -a command. |
5.0.0-5.2.1 | 5.3.0-5.11.0 |
| 3195345 |
Communication between single-connected MLAG hosts on different switches fails because packets received by single-connected MLAG hosts are not forwarded over the peer link. To work around this issue, when adding a switch to an MLAG pair, enable all the interfaces. | 5.0.0-5.0.1 | 5.1.0-5.11.0 |
| 3192808 |
When the switch receives an LLDP frame from a Cisco router right after a ptmd restart, the ptmd service crashes. |
4.3.0-4.3.1, 4.4.0-5.2.1 | 4.3.2, 5.3.0-5.11.0 |
| 3157240 |
When you try to query REDECN counters with the mlxcmd utility on a bond member port with the following commands, syslog reports an errorsudo /usr/lib/cumulus/mlxcmd roce counters –port |
4.4.4-5.1.0 | 5.2.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3142615 |
The BGP4-MIB.txt file is missing from Net-SNMP agent. |
5.0.0-5.4.0 | 5.5.0-5.11.0 |
| 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 |
5.0.1-5.8.0 | 5.9.0-5.11.0 |
| 3141818 |
If there is extensive and continuous next-hop group (NHG) churn when routes keep moving from one NHG to another NHG repeatedly, switchd increases in memory allocation until memory is exhausted. Other processes might be affected as they try to acquire memory which is unavailable. |
5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3138746 |
The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 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 | 5.3.0-5.11.0 |
| 3136983 |
When a layer 3 neighbor entry resolves to a bridge FDB entry that does not exist in the kernel, switchd might contribute to high CPU load while it continues to try to sync and resolve the neighbor entry. This results in many sync_l3_nexthop messages printed to /var/log/switchd.log. |
5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 3136905 |
When you upgrade from Cumulus Linux 5.0.1 to Cumulus Linux 5.1.0, the upgrade adds KexAlgorithms and MACs configuration to the /etc/ssh/sshd_config file without prompting for confirmation. This might cause the /etc/ssh/sshd_config file to be incorrect if there is a Match section; KexAlgorithms and MACs must come before Match. To work around this issue, move the lines that start with KexAlgorithms and MACs before Match or remove them, then restart the SSH service with the sudo systemctl restart ssh command. If you have already specified KexAlgorithms or MACs, you can remove the newly added lines after upgrade. |
5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 3131423 |
During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. |
4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3123556 |
When you configure an interface in FRR to send IPv6 RAs before you configure the interface in the /etc/network/interfaces file, the switch does not process IPv6 RAs. To work around this issue, remove the interface configuration in FRR and reapply it. |
3.7.15-4.3.0, 4.4.0-5.1.0 | 4.3.1, 5.2.0-5.11.0 |
| 3119673 |
If the switch receives an EVPN route with multiple RTs that match the import policy for a local VNI, the bgpd service crashes. |
5.0.0-5.1.0 | 5.2.0-5.11.0 |
| 3119615 |
In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.11.0 |
| 3117340 |
When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service. To recover, restart the networking service with the sudo systemctl restart networking command. |
4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3115415 |
In the Cumulus-BGPVRF-MIB, the bgpPeerFsmEstablishedTime OID does not correctly report the time since a BGP session goes down. |
4.4.4-5.1.0 | 5.2.0-5.11.0 |
| 3112971 |
When you configure a VRF static route using the legacy command syntax in FRR (for example: ip route 10.0.0.0/8 172.16.1.1 vrf vrf-red), then make subsequent VRF or route configuration changes, FRR might crash. To avoid this problem, use the current method for configuring VRF routes within the VRF stanza:vrf vrf-red |
4.4.3-5.1.0 | 5.2.0-5.11.0 |
| 3112938 |
In the Cumulus-BGPVRF-MIB, the bgpPeerFsmEstablishedTransitions OID always reports a value of 0. |
4.4.4-5.1.0 | 5.2.0-5.11.0 |
| 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, 5.0.0-5.11.0 | 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, 5.0.0-5.11.0 | |
| 3081232 |
On the NVIDIA Spectrum 1 switch, when a port goes down, it might not come back up. To work around this issue, disable, then enable the port. | 5.0.0-5.1.0 | 4.4.4-4.4.5, 5.2.0-5.11.0 |
| 3077736 |
When you run the NVUE command to change the minimum interval between received BFD control packets or the minimum interval for sending BFD control packets, the configuration apply fails.
|
5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 3077547 |
When you configure multiple multicast RPs with groups matched by prefix lists, Cumulus Linux selects only one of the RPs and this selection is incorrect. | 5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 3077513 |
When a MAC address is moved to a new VTEP in an EVPN MAC mobility scenario using traditional bridges, there might be up to 30 seconds of convergence delay. | 5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 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 | 5.4.0-5.11.0 |

When you add an interface to a layer 3 bond, traffic does not forward and you see errors similar to the following:2022-05-02T13:14:40.118597+00:00 cumulus sx_sdk: ROUTER: Failed to delete router interface(27) ref count isn’t 0, err= Resource is in use |
4.4.2-4.4.3, 5.0.1-5.11.0 | 4.4.4-4.4.5 |
| 3059380 |
When you configure VRF leaking from the default VRF to a non-default VRF, SSH sessions originating from the switch CLI in the default VRF do not connect to devices in the non-default VRF. | 5.0.1-5.1.0 | 5.2.0-5.11.0 |
| 3059135 |
In an OSPF configuration, after you change the IPv6 subnet mask, the old address remains in the RIB as a connected OSPF route To resolve this issue, restart FRR with the sudo systemctl restart frr command. |
4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3055255 |
When you run the NVUE nv show interface command, a watchdog timeout might occur and the nvued service fails. |
5.0.1 | 5.1.0-5.11.0 |
| 3054869 |
When you run NVUE commands as part of ZTP scripts, the commands fail with errors that indicate a missing $HOME environment variable. The issue has been fixed where the ZTP module initializes the $HOME environment variable before launching the ZTP scripts. However, if you are running older releases, before you use any NVUE commands in the ZTP script, add a section and define the HOME environment variable. Populate the variable with the default expected root user home directory value (/root), then export the HOME variable so it is available globally for NVUE to useHOME=/rootexport HOME |
5.0.0-5.1.0 | 5.2.0-5.11.0 |
| 3046023 |
The cl-resource-query command output shows ECMP nextHop Table exhaustion (above 100 percent utilization) and the switchd.log file contains ECMP resource errors with routes and next hops failing to install. |
4.2.1-5.1.0 | 5.2.0-5.11.0 |
| 3044596 |

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 | 5.5.0-5.11.0 |

PBR rules that you apply to interfaces in the default VRF install in the kernel with the action lookup local. As a result, packets that match this rule only perform a route lookup in the local table (which contains special routes for local IP addresses and broadcast addresses) but not in the main table (which contains unicast routes). As a result, policy routing might be applied to traffic incorrectly. |

You see a critical error in the log file similar to:CRITICAL: cue_versions_v1.repo: The NVUE internal data store is corrupted or has been initialized incorrectly. The is an unrecoverable errorTo work around this issue, remove the /var/lib/nvue/config and /var/lib/nvue/meta directories, then restart the nvued service with the sudo systemctl start nvued command. If possible, NVUE recovers user configuration and saves it in the /etc/nvue.d directory. The recovered configuration will be saved as YAML files, which are named as nvue-recovery-.

CVE-2023-38408: The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009 Mitigation: Do not use ssh-agent forwarding (the man page for ssh_config says that “agent forwarding should be enabled with caution”), or start the ssh-agent program with the -P option to allow only specific PKCS#11 libraries (or none with -P ‘') For Cumulus Linux 4.3.2, the /usr/bin/ssh-agent program has all permissions turned off (chmod 0) to prevent its execution if a vulnerable version is detected. |

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). |

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. |

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. |

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. |
