Open Issues in 5.8.0
Issue ID | Description | Affects | Fixed |
---|---|---|---|
4182753 |
When you configure the SPAN port mirror truncate size to a value greater than 4 and less than the supported minimum, NVUE allows the configuration even though there are errors and failures in the mirror session configuration. The supported values for truncate size are 32 to 4088 for Spectrum 1, 48 to 4088 for Spectrum-2 and Spectrum-3, and 64 to 4088 for Spectrum-4. To work around this issue, run the echo <supported_value> > /cumulus/switchd/config/mirror/session/1/truncate_size command before you reconfigure mirror sessions with the supported values. |
5.8.0-5.11.0 | |
4134451 |
When you set the SNMP server listening address to listen on all IPv4 and IPv6 addresses in a VRF with the nv set service snmp-server listening-address all vrf and nv set service snmp-server listening-address all-v6 vrf commands,SNMP requests over IPv6 addresses do not work. |
5.8.0-5.10.1 | 5.11.0 |
4101027 |
After you add a VLAN to a bridge member port, you might experience a few seconds of VXLAN traffic loss. | 5.7.0-5.10.1 | 5.11.0 |
4100164 |
Low power Intel SATA controllers experience issues when using the mobile low power chipset LPM policy. This can cause the SSD to become read only. |
5.8.0-5.10.1 | 5.11.0 |
4086714 |
Some STP interfaces might remain in a blocking state when there are large numbers of dis-contiguous VLANs enabled on a port. | 5.8.0-5.10.1 | 5.11.0 |
4072165 |
When you add a VLAN to a bridge member port, VXLAN traffic might be impacted for few seconds. | 5.7.0-5.10.1 | 5.11.0 |
4063273 |
Low power Intel SATA controllers experience issues when using the mobile low power chipset LPM policy. This can cause the SSD to become read only. |
5.8.0-5.10.1 | 5.11.0 |
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 |
4035681 |
The nv show interface commands show RX and TX Power values from the wrong lanes on breakout ports. |
5.8.0-5.9.1, 5.10.0-5.10.1 | 5.9.2, 5.11.0 |
4023649 |
On rare occasions when certain events occur, such as changes to the topology in the network, when a bond comes online and directly transits to an STP blocking state, the slave ports might still be in a forwarding state. As a result, traffic is forwarded on a blocked port. | 5.2.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
4007614 |
Static ARP configured with NVUE commands is deleted when the relevant layer 3 interface flaps. | 5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982294 |
Cumulus Linux does not recognize QSFP_CMIS optical modules correctly. | 5.6.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982260 |
When you modify the default QoS configuration on top of the base RoCE configuration, NVUE reports an Invalid exception in the nv show qos roce command output even when the configuration is valid. |
5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982249 |
If a packet containing an all zero source MAC address (00:00:00:00:00:00) is learned on the ASIC, switchd sends the learn notification to the kernel but the kernel rejects the MAC address as invalid. The ASIC continuously sends the mac-learn notifications, which wastes CPU resources. To work around this issue, configure ACLs to match on the all-zero source MAC address and drop the invalid packets. |
5.5.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982242 |
PTP does not come up with IPv6 over a trunk port because the IPv6 VLAN tag is not sent. PTP over an IPv4 trunk works fine. | 5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982234 |
With LACP bypass enabled, Cumulus Linux does not program the MAC address in the bridge FDB for VLAN unaware tagged ports. With EVPN, the address is not advertised and the remote side might flood the packet instead of unicast. | 5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982233 |
When you enable Optimized Multicast Flooding (OMF) and change VLAN configuration, a few ports might carry multicast traffic even when they are not in the MDB or they are not router ports. | 5.6.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982231 |
The switch forwards multicast traffic to the CPU when PIM is enabled globally, regardless of the interface configuration. | 5.6.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982230 |
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 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3982226 |
When SPAN is enabled on a bridge member, an ARP or Gratuitous ARP received during a failover event between locally attached redundant devices such as load balancers might fail to update the bridge MAC table to point to the interface with the newly active load balancer. | 5.4.0-5.9.1 | 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 |
3980938 |
When ARP suppression is off, remote EVPN VTEPs duplicate ARP packets from local hosts and each remote host receives two copies of the ARP packets. The issue also applies to IPv6 ND packets. | 5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3980925 |
When you configure the bridge.kernel_mac_refresh_interval parameter in the switchd.conf file, a switchd restart fails with a core dump. |
5.8.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3965573 |
If you use NVUE to create an SNMP user with a password, then delete and recreate the user with additional encryption passwords (such as DES or AES), SNMP authorization fails for that user. | 5.3.1-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
3875419 |
The cleanup scrip inadvertently removes the active LTTng session directory used by lttng-sessiond for trace dumping. This issue occurs under specific conditions when more than five LTTng trace folders are present, leading to intermittent failures in trace logging. To work around this issue, manually move the timestamped lttng logs to a different directory. |
5.8.0 | 5.9.0-5.11.0 |
3863858 |
VRR interfaces might show dadfailed on their IPv6 link-local address. |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3863063 |
When simultaneously changing the maxage and forward-delay bridge timers in RSTP for VLAN-aware bridges, the commands might not be accepted if the 2xfdelay-1 is less than the previously configured maxage timer because ifupdown2 configures the forward delay first. To work around this issue, run the ifreload -a command again to process the forward-delay command after the new maxage configuration has been accepted. You have to repeat the ifreload -a command after a reboot to set the forward delay correctly in the bridge. |
5.8.0 | 5.9.0-5.11.0 |
3837121 |
With a large route map and community list configuration, FRR reload takes much longer than normal (approximately 13 seconds) and in some cases, CPU utilization is high. | 5.8.0 | 5.9.0-5.11.0 |
3832116 |
When you configure a SPAN session either with the NVUE nv set system port-mirror session command or in the /etc/cumulus/switchd.d/port-mirror.conf file and the default route is configured to 0.0.0.0/0, the SPAN session might not work as expected. To work around this issue, remove the default route 0.0.0.0/0 and use alternate routes instead. |
5.7.0-5.8.0 | 5.9.0-5.11.0 |
3828243 |
After you change the remote AS for a peer group, the switch no longer has any peers associated with the peer group. To work around this issue, reconfigure all the associated peers after you change the remote AS for the peer group. | 5.8.0 | 5.9.0-5.11.0 |
3824750 |
With the nvidia.nvue Ansible module, NVUE honors input from the Ansible module only; if you do not provide the full configuration, NVUE generates an exception. To work around this issue, always provide the full configuration. |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3813710 |
The What Just Happened service (wjhd ) fails to start if an interface alias (description) contains the text Ethernet and add syslog messages similar to the following:router1: wjhd: exception: stoirouter1: wjhd: Fail to deinit SDK telemetry, error: [3]: [Invalid Handle] |
5.8.0 | 5.9.0-5.11.0 |
3812857 |
When enabling telemetry on an interface, NVUE doesn’t validate if some of the configuration is correct. For example if you configure swp1s0, but enter swp1 by mistake, NVUE accepts and applies this configuration. If the ASIC monitor service finds that this port is not available, it skips the configuration associated with this port. NVUE applies configuration for other valid ports as expected. | 5.8.0 | 5.9.0-5.11.0 |
3800536 |
Some third-party modules cause false-alarm interrupts during SERDES tuning, which overloads the ASIC and causes an ASIC response delay. | 5.8.0 | 5.9.0-5.11.0 |
3798580 |
With ROCE enabled, LLDP DCBX TLVs might carry an incorrect PFC map when bond interfaces are present on the switch. | 5.8.0 | 5.9.0-5.11.0 |
3782996 |
If you have installed a large number ACLs, you might see a switchd memory leak over a period of time that stops the switchd process because it is out of memory . |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3782543 |
When you configure the BGP setting bgp max-med on-startup with vtysh, the MED on some peers might not be set to 4294967294 as expected on startup. The max-med might also fail to reset after the startup timer expires. |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3775686 |
The BGP Suppress Route Advertisement feature under scale (more than 30000 routes) advertises partial updates to downstream neighbors. Because FRR does not read kernel route updates fast enough, the netlink socket receive buffer gets full and further update notifications are dropped. | 5.8.0-5.9.2 | 5.10.0-5.11.0 |
3775648 |
Enabling or disabling link utilization causes the switchd service to restart, which causes all network ports to reset, interrupts network services, and resets the switch hardware configuration. |
5.8.0 | 5.9.0-5.11.0 |
3774274 |
When you manually configure the /etc/cumulus/datapath/qos/qos_features.conf file without applying the QoS configuration with NVUE, running the nv config apply empty command later does not clean up the QoS configuration. If the QoS configuration includes breakout ports, the nv config apply empty command fails due to a switchd reload trigger failure. To work around this issue, clean up the configuration manually in the /etc/cumulus/datapath/qos/qos_features.conf , then run the nv config apply empty command. |
5.8.0-5.11.0 | |
3773991 |
When you use warm mode to reboot a switch with a large number of EVPN routes and BGP graceful restart is enabled, stale routes might be relearned from BGP neighbors after the switch boots. This might cause traffic loss until BGP is fully converged after the reboot. | 5.8.0 | 5.9.0-5.11.0 |
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 | |
3771168 |
When you perform an ISSU upgrade on a Spectrum 1 switch, the switchd service might crash. |
5.8.0-5.11.0 | |
3770993 |
When a supplicant is authorized successfully on an interface in 802.1x multi-host mode, ping traffic coming into the 802.1x interface towards a local SVI might not be successful. |
5.8.0 | 5.9.0-5.11.0 |
3770865 |
On the NVIDIA SN5600 switch, performing a fresh image install or a power cycle can cause the PCIE link speed to get downgraded from Gen3(8GTs) to Gen1(2.5GTs). To recover, reboot the switch. | 5.8.0 | 5.9.0-5.11.0 |
3767037 |
When you try to upgrade a switch from Cumulus Linux 5.5 or earlier to 5.8.0 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:~$ sudo apt-get updatecumulus@switch:~$ sudo apt-get install –allow-unauthenticated cumulus-archive-keyring |
5.8.0 | 5.9.0-5.11.0 |
3765395 |
The nv unset nve vxlan flooding and nv set nve vxlan flooding enable off commands do not disable BUM flooding. To work around this issue, disable BUM flooding with vtysh commands:leaf01# configure terminal |
5.5.0-5.8.0 | 5.9.0-5.11.0 |
3759515 |
After upgrading to Cumulus Linux 5.8, MLAG reports bonds as bpdu guard mismatch . To work around this issue, restart the MLAG service with the systemctl restart clagd on the device that reports the conflict. |
5.8.0 | 5.9.0-5.11.0 |
3753050 |
On Spectrum 1 switches, switchd might crash due to an SDK health event or error. |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3752266 |
If you configure DHCP Server HA, the switch failover might cause the DHCP service to report a time mismatch too great error. |
5.7.0-5.8.0 | 5.9.0-5.11.0 |
3744830 |
When configured with NVUE, the Radius secret key can be a maximum of 19 characters long. | 5.7.0-5.8.0 | 5.9.0-5.11.0 |
3739008 |
The Lenovo MSN4600-VS2RC (PN SSG7B27990 Back-to-Front/C2P Airflow) might run the fan tray fans at a high speed because the software believes the PSU fans are running in the wrong direction. | 5.5.1-5.8.0 | 5.9.0-5.11.0 |
3730904 |
When sending untagged frames to the CPU with an MTU higher than the SVD (single VXLAN device) MTU, the kernel might crash. | 5.4.0-5.8.0 | 5.9.0-5.11.0 |
3711913 |
When you set an IPv4 ACL with a log action, logs do not appear under syslog after a match. This issue affects bridged packets when the rule is installed in iptables. To work around this issue, set the ACL with a MAC rule type so that it is installed in ebtables and the packets are logged correctly in syslog .The following shows an example configuration: cumulus@switch:~$ nv set acl one rule 1 action log log-prefix NVIDIA |
5.7.0-5.9.2 | 5.10.0-5.11.0 |
3702431 |
Traditional SNMP snippets do not take effect unless you first enable SNMP with the NVUE nv set service snmp-server enable on and nv set service snmp-server listening-address commands. Alternatively, you can use the equivalent REST API methods. |
5.4.0-5.8.0 | 5.9.0-5.11.0 |
3679478 |
During switch boot, you see the following messages in the syslog:2024-03-04T10:34:49.650950+00:00 cumulus sx_sdk: 2262 [TELE] [ERROR ]: Tele impl module is already initialized2024-03-04T10:34:49.651041+00:00 cumulus sx_sdk: 2262 [TELE] [ERROR ]: sdk_tele_init failed, for chip type CHIP_TYPE_SWITCH_SPECTRUM3, err = Already initialized This is due to both the ASIC Monitoring service and the What Just Happened (WJH) service trying to initialize the SDK TELE module. You can ignore the messages because the TELE service has already initialized properly. |
5.7.0-5.8.0 | 5.9.0-5.11.0 |
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. |
5.7.0-5.11.0 | |
3672706 |
When you enable port security, you can configure a maximum of 450 port security static MAC addresses for an interface. | 5.7.0-5.8.0 | 5.9.0-5.11.0 |
3655681 |
When you disable, then enable STP auto-edge on a port, the port might not transition to the operational edge even though the port does not receive bpdus. To work around this issue, configure the port as an admin-edge port. | 5.7.0-5.11.0 | |
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 . |
5.7.0-5.11.0 | |
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. |
5.7.0-5.9.2 | 5.10.0-5.11.0 |
3610967 |
In an EVPN symmetric routing configuration, running the NVUE nv set vrf command to derive layer 3 VNIs automatically might result in duplicate VLAN entries in the system. This most often occurs at scale when many VRFs have similar names. To work around this issue, manually specify a unique VLAN for each VRF. |
5.3.0-5.8.0 | 5.9.0-5.11.0 |
3610591 |
After configuring the system level pre-login and post-login banner messages, the messages do not return to their default settings when you run the nv unset system command or the nv config apply empty command. |
5.7.0-5.9.2 | 5.10.0-5.11.0 |
3591918 |
The nv action disconnect system aaa user command does not clear all the open sessions. To work around this issue, run the command as many times as the number of sessions to clear all the sessions. |
5.6.0-5.11.0 | |
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:

5.6.0-5.11.0 | |
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. | 5.5.0-5.11.0 | |
3546857 |
The nv show bridge vlan command does not show tagged and untagged VLAN information for the bridge |
5.6.0-5.8.0 | 5.9.0-5.11.0 |
3541653 |
During warm boot with layer 3 traffic, you might experience packet loss for approximately 15 milliseconds. | 5.6.0-5.8.0 | 5.9.0-5.11.0 |
3540510 |
400Gx8 ports only support traffic line rate with packets that are larger than 172 bytes. | 5.6.0-5.11.0 | |
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. | 5.6.0-5.11.0 | |
3497622 |
When you remove PSUs, then plug them back in, you might experience traffic loss and some ports might be in a down state. | 5.6.0-5.11.0 | |
3484058 |
When you power on the NVIDIA SN3420 switch with no connected cables, the QSFP ports LEDs light in amber. | 5.3.0-5.8.0 | 5.9.0-5.11.0 |
3472163 |
On a switch with the Spectrum-4 ASIC, packets that are smaller than 256 bytes are not included in multicast flows. Multicast flows support packets that are 256 bytes or larger. | 5.6.0-5.11.0 | |
3470940 |

Migration from ONYX to Cumulus Linux is supported and tested with ONYX version 3.10.4302 GA only. | 5.6.0-5.11.0 | |
3442569 |
When trying to access the NVUE API, user accounts authenticated with a newly-configured external service, such as TACACS, RADIUS, or LDAP, receive a 401 forbidden error. To work around this issue, after enabling a new authentication service, make sure to restart both nginx.service and nvued.service to begin authenticating users against the new authentication service. |
5.5.0-5.11.0 | |
3433577 |
When you use a single VXLAN device (SVD) with MLAG and static VXLAN tunnels, Cumulus Linux incorrectly associates the MAC addresses it learns from the VXLAN fabric to the bridge PVID. This issue can lead to a feedback loop between the clagd service and switchd , and might result in critical CPU usage with an out of memory condition. Do not use an SVD when enabling MLAG in a static VXLAN environment. |
5.5.0-5.8.0 | 5.9.0-5.11.0 |
3430430 |
When you configure PTP on 50G ports, the offset correction might be higher, which can affect the time synchronization of the node. To work around this issue, configure PTP on 100G ports, or on 10G or 1G ports with PTP shaper enabled. | 5.5.0-5.11.0 | |
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 | |
3393966 |
When you configure OSPF network statements using NVUE with the nv set vrf command, subsequent configuration changes with NVUE might bring down all OSPF neighbors. To work around this issue, create an NVUE snippet to configure the network statement, or use the nv set interface command to enable OSPF on interfaces instead of using a network statement. |
5.5.0-5.9.2 | 5.10.0-5.11.0 |
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. |
5.4.0-5.11.0 | |

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 |

Cumulus Linux 5.6 and 5.7 do not include FRR log rotation, which can result in a very large log file that affects disk usage. To work around this issue, run the following commands as the cumulus user on the Cumulus Linux 5.6 or 5.7 switch. The commands do not impact any other system function.cumulus@switch:~$ wget https://download.nvidia.com/cumulus/apt.cumulusnetworks.com/repo/pool/cumulus/f/frr-logrotate/frr-logrotate_8.4.3-0+cl5.7.0u1_amd64.deb |

Configuring the number of lanes per port after breaking out the port is not effective. To work around this issue, first unset the breakout with the nv unset interface and nv config apply commands, then reconfigure the breakout and the lanes with the nv set interface command. For example:cumulus@switch:~$ nv unset interface swp1 link breakout cumulus@switch:~$ nv config apply cumulus@switch:~$ nv set interface swp1 link breakout 2x lanes-per-port 2 cumulus@switch:~$ nv config apply |

Routes and/or next-hops will no-longer be installed in kernel, and traffic related to these routes and/or next-hops will not be forwarded correctly. Flapping of EVPN prefixes from BGP updates and withdraws sometimes causes a race condition where the routes are never re-installed. An example of a trigger that can lead to this problem is a flapping peerlink. A reboot of each switch with missing routes will recover from this issue. | 5.6.0-5.7.0 |
3632843 |
When the switch receives a type-5 route in BGP and there is a network statement for the same prefix, BGP sometimes removes the request to track next hops from FRR. As next hop reachability changes, BGP no longer reacts to the change. To work around this issue, run the clear bgp * command for all peerings. |
