If you configure the anycast IP address with the nv set nve vxlan mlag shared-address command after you configure MLAG, the anycast IP address configuration is not applied and the VXLAN interface is in a protodown state. To work around this issue, run sudo ifreload -a . To avoid this issue, either apply the anycast configuration before you apply the MLAG configuration or configure the anycast IP address and MLAG together with a single nv config apply command. |
5.9.0-5.9.1 | |

When ZTP runs a script that contains wget , ZTP fails and you see a message similar to the following:ZTP: ZTP DHCP: Unexpected error: ‘ascii’ codec can’t decode byte 0xe2 in position 181: ordinal not in range(128)ZTP: Script returned failure To work around this issue, use the -q option with wget . |
5.9.0-5.9.1 | |
3875696 |
The default TX State for 1G Base-X optical modules that are unconfigured or admin down in Cumulus Linux 5.7.0 and later is OFF. However, on the first boot after upgrade from an earlier release, a module TX power might be ON or OFF depending on the TX State it was before the upgrade. The TX_Disable line is not properly set on first boot. To work around this issue, reboot the switch again, or ifup or ifdown the 1G Base-X interface to disable TX Power. |
5.7.0-5.9.1 | |
3875243 |
When you run the nv config replace command and try to apply the configuration, you receive the following log message:Invalid config [rev_id: 2]This occurs when you try to replace the default NVUE configuration for the cumulus user account credentials. To work around this behavior, merge your configuration into the current applied configuration with the nv config patch command instead. |
5.9.0-5.9.1 | |
3873219 |
When you remove a port from a bond and add it to the bridge in a single set of NVUE commands, then apply the configuration, the port forwarding state is blocked on all the bridge VLANs. To work around this issue, apply the configuration in two steps. First remove the port from the bond and apply the configuration, then add the port to the bridge and apply the configuration. | 5.9.0-5.9.1 | |
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 | |
3851499 |
On the Spectrum A1 switch, when you enable the ip-acl-heavy TCAM profile, VXLAN tunnel initialization might fail. |
5.8.0-5.9.1 | |
3844670 |
When you configure TACACS with NVUE or merge in an NVUE configuration file including TACACS configuration with the nv config patch command, you see an unrecoverable error when running additional NVUE commands. To work around this issue, restart the NVUE service with the systemctl restart nvued.service command. |
5.9.0-5.9.1 | |
3775686 |
Suppress route advertisement for BGP under scale (more than 30000 routes) advertises partial updates to downstream neighbors. Because FRR reads kernel route updates slowly, the netlink socket receive buffer gets full and further update notifications are dropped. | 5.8.0-5.9.1 | |
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, 5.0.0-5.9.1 | |

When you perform an ISSU upgrade on a Spectrum 1 switch, the switchd service might crash. |
5.8.0-5.9.1 | |
3739159 |
Disabling adaptive routing globally or on interfaces and performing ISSU, has a significant traffic outage. The issue recovers after ISSU completes. | 5.7.0-5.9.1 | |
3685007 |
Cumulus Linux does not support 802.1X dynamic VLANs on PEAP with MS Windows-based supplicants. | 5.7.0-5.9.1 | |
3677533 |
Due to resource constraints on the Spectrum 1 switch, staticd performance drops and takes longer to read static routes compared to the time BGP takes to complete a graceful restart, and advertise routes and EOR to its helpers. As a result, static routes are advertised after the EOR is sent to graceful restart helpers, which delete the stale static routes and relearn them after receiving the EOR from the restarting node. Temporary traffic loss might occur. |
5.7.0-5.9.1 | |
3637444 |
Applying an inbound control plane ACL on the eth0 management interface does not take effect. To work around this issue, apply the ACL on the mgmt interface; for example, nv set interface mgmt acl . |
5.7.0-5.9.1 | |
3636266 |
When an unresolved next hop is present in a next hop group, especially over an SVI interface, the switch checks if the neighbor MAC address is in the forwarding table. If the neighbor’s MAC address is not there, the switch skips this next hop from backend programming and you see the switchd error ERR NH: l3 nhg v6 l3 nhg contains one or more unresolvable nexthops . There is no impact to switch functionality as unresolved neighbors are not programmed in hardware until they are resolved. |
5.7.0-5.9.1 | |
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:

5.6.0-5.9.1 | |
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. | 5.5.0-5.9.1 | |
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. | 5.6.0-5.9.1 | |
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 . |
5.5.0-5.9.1 | |
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. |
5.0.0-5.9.1 | |
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, 5.0.0-5.9.1 | |
3393966 |
Configuring the network statement with the NVUE nv set vrf command might bring down all the OSPF neighbors. To work around this issue, create an NVUE snippet to configure the network statement. |
5.5.0-5.9.1 | |
3368217 None |
When daylight saving time changes, the MLAG initDelay timer resets and all MLAG bonds go down. |
4.4.4-4.4.5, 5.2.1-5.9.1 | |
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. |
5.4.0-5.9.1 | |
3350027 |
If you uninstall dynamic NAT rules and switchd restarts before all the dynamic NAT flows age out and are deleted, you might see dynamic flow deletion errors in switchd.log . These errors do not affect new dynamic NAT flows from new NAT rules. |
5.4.0-5.9.1 | |
3347538 |
When connecting NVIDIA-to-NVIDIA in PAM4, you must enable auto-negotiation. | 5.4.0-5.9.1 | |
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. |
5.4.0-5.9.1 | |
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 . |
5.4.0-5.9.1 | |
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, 5.0.0-5.9.1 | |
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. | 5.4.0-5.9.1 | |
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. |
5.3.0-5.9.1 | |
3226506 |
The l1-show eth0 command does not show port information and is not supported in this release. |
5.3.0-5.9.1 | |
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. | 5.2.0-5.9.1 | |
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. |
5.3.0-5.9.1 | |
3145869 |
On a Spectrum-3 switch, the PTP offset in 10GbE changes between +-27. The average offset is around 7. | 5.2.0-5.9.1 | |
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 |
5.2.0-5.9.1 | |
3122301 |
On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.9.1 | |
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. |
5.1.0-5.9.1 | |
3103821 |
On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.9.1 | |

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, 5.0.0-5.9.1 | |
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, 5.1.0-5.9.1 | |
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. | 5.1.0-5.9.1 | |
3053094 |
