Open Issues in 5.9.2
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4185426 |
When you add a new MLAG bond, the BPDU guard state of its peer is initialized to False and immediately updated correctly after resync if the bond is up. If the bond is down, resync is not done and the peer PBDU guard state is not updated, which leads to a conflict if the local PBDU guard is enabled. Even though it seems that PBDU configuration does not match between MLAG peers, this issue does not have any functional impact. It gets cleared when the bond becomes up. |
5.9.2-5.11.0 | |
| 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 | |
| 4173498 |
After network churn, the watchfrr process might restart FRR because zebra is unresponsive. |
5.9.1-5.11.0 | |
| 4170604 |
When you configure EVPN multihoming with more than one ESI bond member, you might see intermediate traffic loss. | 5.9.1-5.11.0 | |
| 4170598 |
When you create an ACL rule that matches TCP state and more than seven TCP or UDP source or destination ports, the rule does not get framed properly and is rejected by the kernel. To work around this issue, create another rule number when the number of ports you want to match is more than seven. |

5.9.1-5.11.0 | |
| 4129344 |
When you create an ACL rule that matches TCP state and more than seven TCP or UDP source or destination ports, the rule does not get framed properly and is rejected by the kernel. To work around this issue, create another rule number when the number of ports you want to match is more than seven. |
5.9.1-5.10.1 | 5.11.0 |
| 4124831 |
When Per-VLAN Rapid Spanning Tree (PVRST) mode is enabled, bonds with LACP bypass discard ingress DHCP packets. | 5.9.1-5.10.1 | 5.11.0 |
| 4119621 |
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. |
5.8.0-5.11.0 | |
| 4115126 |
When IPv4 layer 3 switch ports and virtual interfaces flap, switchd might send an ICMP Reply message instead of an ARP request (although no ICMP request was sent). Multiple ICMP Replies might be sent to any of the neighbor IP addresses of that interface. |
5.9.2-5.11.0 | |
| 4102992 |
When you use the NVUE nv set bridge domain command to configure the STP priority on two bridges, the STP priority on the second bridge does not apply.To work around this issue, configure an NVUE snippet for the second bridge and apply it to the switch; for example: Create the vlan-aware_bridge_snippet.yaml file and add the following:- set: Save the file, run the nv config patch vlan-aware_bridge_snippet.yaml command, then the nv config apply command. |
5.9.1-5.11.0 | |
| 4101808 |
When the SNMP service is busy for approximately more than a minute, the applications using net-snmp APIs to support their MIBs (such as FRR) become blocked. |
5.9.0-5.10.1 | 5.11.0 |
| 4101027 |
After you add a VLAN to a bridge member port, you might experience a few seconds of VXLAN traffic loss. | 5.7.0-5.11.0 | |
| 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. |
5.8.0-5.11.0 | |
| 4096505 |
In an EVPN configuration, when you use NVUE to configure a new host bond and an multihoming ESI at the same time, the Split-Horizon preventive traffic class rule is not programmed in the egress direction. To work around this issue, configure the host bond and apply the configuration, then configure the EVPN multihoming ESI on the host bonds and apply the configuration in a separate step. | 5.9.1-5.11.0 | |
| 4081784 |
If you configure an inbound route policy that drops prefixes, running the vtysh show bgp vrf command might crash the BGP service.Avoid running the vtysh show bgp vrf command if you configure a drop inbound route policy. |
5.9.1-5.11.0 | |
| 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 |
| 4066219 |
Some STP interfaces might remain in a blocking state when there are large numbers of dis-contiguous VLANs enabled on a port. | 5.8.0-5.11.0 | |
| 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 |

If there are multiple relay switches in the path reaching the DHCP server, DHCP packets are duplicated at each transit relay switch and the server receives duplicate packets. | 5.9.1-5.11.0 | |
| 3985600 |
NTP initialization issues prevent the NTP service from starting on a non-default VRF. | 5.9.0-5.9.2 | 5.10.0-5.11.0 |
| 3915878 |
If you configure remote syslog export through a non-default VRF, you might see repeated error logs from the rsyslog process while the switch is booting:rsyslogd: create UDP socket bound to device failed: No such device [v8.2302.0]rsyslogd: No UDP socket could successfully be initialized, some functionality may be disabled. [v8.2302.0] The logs occur because the rsyslog service starts before the networking service creates the configured VRF for syslog export. There is no functional impact with this issue. |
5.9.0-5.11.0 | |
| 3890993 |
On the NVIDIA spectrum-4 switch, l1-show command output does not show Eye opening information for an interface port. |
5.9.0-5.9.2 | 5.10.0-5.11.0 |
| 3879809 |
What Just Happened (WJH) does not work on Spectrum-4 switches. | 5.9.0-5.11.0 | |
| 3878699 |
In an EVPN multihoming configuration, when the VXLAN device associated with a layer 2 VNI flaps, there is a route entry in the tenant VRF associated with the locally learned host. | 5.9.0-5.10.1 | 5.11.0 |
| 3878394 |
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. |
5.9.0-5.11.0 | |
| 3877516 |
When you connect two NVIDIA switches and configure 400G speed in force mode, links don’t come up. To work around this issue, make sure auto negotiation is always on when connecting NVIDIA to NVIDIA in PAM4. |
5.9.0-5.11.0 | |
| 3875373 |
When you run the nv config apply empty command, NVUE removes the cumulus user. If you are logged in as the cumulus user when you run the nv config apply empty command, the command fails. |
5.9.0-5.11.0 | |
| 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. | 5.9.0-5.9.2 | 5.10.0-5.11.0 |
| 3861745 |
On UEFI hardware (where the /sys/firmware/efi directory exists), using the update-grub program might generate a /boot/grub/grub.cfg that is incorrect for booting ONIE if the ONIE option is selected on the console while booting. To work around this issue, run mount LABEL=“EFI System” /boot/efi before using update-grub. |
5.9.0-5.11.0 | |
| 3855796 |
When configuring a Unicast Master Table for clients, the server addresses must be reachable and the route to the destination must exist. The unicast table can have one directly-connected port for a client. This restriction is only for directly connected ports and doesn’t apply to Unicast Servers on other devices or switches. | 5.9.0-5.11.0 | |
| 3847439 |
In rare cases on the Spectrum 1 switch where a dual connected host transmits all traffic flows to only one switch in a connected MLAG pair and the host changes behavior to hash all flows to the other MLAG switch, there might be traffic loss if the MAC FDB entry on the original switch ages out. | 5.9.0-5.11.0 | |
| 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. |
5.9.0-5.11.0 | |
| 3835635 |
When adaptive routing is enabled, traffic for non adaptive routing enabled ports and non adaptive routing ECMPs might be routed over all ports in ECMP. Avoid using regular ECMPs with adaptive routing enabled on the switch. | 5.9.0-5.11.0 | |
| 3819945 |
When you connect an NVIDIA SN4410, SN4700, or SN5600 switch to any Spectrum 1, Spectrum-2, or Spectrum-3 peer switch (with four lanes) using a 4x breakout configuration and the default lanes per port setting, links do not come up. To work around this issue, provide the lanes per port configuration shown below:cumulus@switch:~$ nv set interface |
5.9.0-5.11.0 | |
| 3818545 |
The terminal monitoring software SecureCRT has a known issue when running on both Windows and Mac systems where it gets “stuck” when monitoring the serial port of the switch as Cumulus Linux boots up. When this occurs, the serial port stops as shown below and SecureCRT is unable to receive any more serial data from the switch (it is able to transmit).Mounting dev-hugepages.mount - Huge Pages File System.. |
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 |
| 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 | |
| 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 | |
| 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 |
| 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 | |
| 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 |
| 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 | |
| 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 | |
| 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 |
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 | |
| 3452681 |
When you run the NVUE nv show system aaa tacacs authorization commands to show per command authorization for a specific TACACS+ user privilege level, you see an error message similar to Error: GET /nvue_v1/system/aaa/tacacs/authorization/1?rev=operational responded with 404 NOT FOUND. |
5.5.0-5.10.1 | 5.11.0 |

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 | |
| 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 | |
| 3347538 |
When connecting NVIDIA-to-NVIDIA in PAM4, you must enable auto-negotiation. | 5.4.0-5.11.0 | |
| 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. |
5.4.0-5.11.0 | |
| 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. |
5.4.0-5.11.0 | |
| 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 | |
| 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. | 5.4.0-5.11.0 | |
| 3253218 |
Auto-negotiation isn’t supported on Spectrum-2 and Spectrum-3 switches using the 1G SFP-T module; FORCE 1G is configured instead. | 5.4.0-5.11.0 | |
| 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. |
5.3.0-5.11.0 | |
| 3226506 |
The l1-show eth0 command does not show port information and is not supported in this release. |
5.3.0-5.11.0 | |
| 3225117 |
Occasionally, packet losses might occur on 25G ports when link is raised without FEC. | 5.4.0-5.11.0 | |
| 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. | 5.2.0-5.11.0 | |
| 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. |
5.3.0-5.11.0 | |
| 3145869 |
On a Spectrum-3 switch, the PTP offset in 10GbE changes between +-27. The average offset is around 7. | 5.2.0-5.11.0 | |
| 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 |
5.2.0-5.11.0 | |
| 3122301 |
On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 5.2.0-5.11.0 | |
| 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. |
5.1.0-5.11.0 | |
| 3103821 |
On the NVIDIA SN4700 switch, inserting and removing the PSU might cause loss of frames. | 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 | |
| 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, 5.1.0-5.11.0 | |
| 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. | 5.1.0-5.11.0 | |
| 3053094 |

If you have SVIs with the same VLANs across more than one bridge, Cumulus Linux installs the router MAC for the first bridge only in the SDK. This can cause reachability issues within that VRF towards this switch from remote VTEPs. To work around this issue, bounce the second bridge with the sudo ifdown and sudo ifup commands. If you reboot the switch, you need to bounce the second bridge again. |

When you start Cumulus VX in Vagrant with libvirt, VM provisioning might fail with errors that indicate a missing ifup@eth0.service systemd service. |
5.9.0-5.9.1 |
| 3917601 |
If a packet containing an all zero source MAC address (00:00:00:00:00:00) is learned on the ASIC, switchd sends the learn notification to the kernel but the kernel rejects the MAC address as invalid. The ASIC continuously sends the mac-learn notifications, which wastes CPU resources. To work around this issue, configure ACLs to match on the all-zero source MAC address and drop the invalid packets. |
5.5.0-5.9.1 |
| 3917528 |
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 |
| 3915842 |
A kernel crash due to memory corruption might occur due to a netfilter error. The log message from netfilter might contain a warning similar to the following:kernel: WARNING: CPU: 1 PID: 0 at net/netfilter/nf_conntrack_core.c:1210 __nf_conntrack_confirm+0x5c7/0x6b0 [nf_conntrack]kernel: RIP: 0010:__nf_conntrack_confirm+0x5c7/0x6b0 [nf_conntrack] |
5.9.0-5.9.1 |

With Optimized Multicast Flooding (OMF), when you unset multiple multicast router ports in a single commit, multicast traffic still floods one of the ports. To work around this issue, unset multicast router ports one by one instead of in a single commit. | 5.9.0-5.9.1 |
| 3896967 |
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 |
| 3895042 |
After an NMS station does a full SNMP walk on the switch, you see the following message every 5 minutes:snmp : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/cumulus/bin/poectl -j -a This issue occurs because poectl is called on non-PoE switches. To work around this issue, remove or comment out the poetcl call from the /etc/snmpd.conf file, then restart the snmpd process with the sudo systemctl snmpd restart command#snmp ALL = NOPASSWD: /usr/cumulus/bin/poectl -j -a |
4.4.0-5.9.1 |
| 3895017 |
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 |
| 3881789 |
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 |
| 3879635 |
ERSPAN port-mirror sessions might not come up after a switchd service restart. To work around this issue and bring up the ERSPAN session, either run switchd reload after a switchd restart or use an ACL-based ERSPAN session. |
5.9.0-5.9.1 |
| 3878166 |
The NVUE nv show interface eth0 and nv show vrf commands take more than two minutes to run if you have configured hundreds of interfaces because NVUE makes repetitive system calls to get vlan/link/tunnel bridge information. |
5.9.0-5.9.1 |
| 3875589 |
MLAG bonds might report an incorrect DOWN reason of lacp partner mac mismatch when the bond is out of service for another reason. |
5.9.0-5.9.1 |
| 3859422 |
On rare occasions when certain events occur, such as changes to the topology in the network, when a bond comes online and directly transits to an STP blocking state, the slave ports might still be in a forwarding state. As a result, traffic is forwarded on a blocked port. | 5.2.0-5.9.1 |
| 3854807 |
When you enable Optimized Multicast Flooding (OMF) and change VLAN configuration, a few ports might carry multicast traffic even when they are not in the MDB or they are not router ports. | 5.6.0-5.9.1 |
| 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 |
| 3821643 |
When using SSM and the upstream interface goes away (the source stops sending or the link goes down) the PIMREG interface is added to the outgoing interface list of the S,G and is never removed. As a result, multicast traffic that hits the impacted S,G is forwarded to the CPU and dropped by the switch. | 5.9.0-5.9.1 |
| 3763543 |
The NVIDIA SN4600C switch fails to boot fully after you upgrade from Cumulus Linux 4.2.1 to 5.7 with ONIE install. To work around this issue, perform an intermediate step image upgrade; for example, upgrade the switch from Cumulus Linux 4.2.1 to 5.2.1 to 5.7.0. |

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. |
5.8.0-5.11.0 | |
| 4102992 |
When you use the NVUE nv set bridge domain command to configure the STP priority on two bridges, the STP priority on the second bridge does not apply.To work around this issue, configure an NVUE snippet for the second bridge and apply it to the switch; for example: Create the vlan-aware_bridge_snippet.yaml file and add the following:- set: Save the file, run the nv config patch vlan-aware_bridge_snippet.yaml command, then the nv config apply command. |
5.9.1-5.11.0 | |

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. |

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. |

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. |

When you start Cumulus VX in Vagrant with libvirt, VM provisioning might fail with errors that indicate a missing ifup@eth0.service systemd service. |
5.9.0-5.9.1 | 5.9.2-5.11.0 |
| 3917601 |
If a packet containing an all zero source MAC address (00:00:00:00:00:00) is learned on the ASIC, switchd sends the learn notification to the kernel but the kernel rejects the MAC address as invalid. The ASIC continuously sends the mac-learn notifications, which wastes CPU resources. To work around this issue, configure ACLs to match on the all-zero source MAC address and drop the invalid packets. |
5.5.0-5.9.1 | 5.9.2-5.11.0 |
| 3917528 |
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 |
| 3915878 |
If you configure remote syslog export through a non-default VRF, you might see repeated error logs from the rsyslog process while the switch is booting:rsyslogd: create UDP socket bound to device failed: No such device [v8.2302.0]rsyslogd: No UDP socket could successfully be initialized, some functionality may be disabled. [v8.2302.0] The logs occur because the rsyslog service starts before the networking service creates the configured VRF for syslog export. There is no functional impact with this issue. |

With Optimized Multicast Flooding (OMF), when you unset multiple multicast router ports in a single commit, multicast traffic still floods one of the ports. To work around this issue, unset multicast router ports one by one instead of in a single commit. | 5.9.0-5.9.1 | 5.9.2-5.11.0 |
| 3896967 |
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 |
| 3895042 |
After an NMS station does a full SNMP walk on the switch, you see the following message every 5 minutes:snmp : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/cumulus/bin/poectl -j -a This issue occurs because poectl is called on non-PoE switches. To work around this issue, remove or comment out the poetcl call from the /etc/snmpd.conf file, then restart the snmpd process with the sudo systemctl snmpd restart command#snmp ALL = NOPASSWD: /usr/cumulus/bin/poectl -j -a |
4.4.0-5.9.1 | 5.9.2-5.11.0 |
| 3895017 |
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 |
| 3890993 |
On the NVIDIA spectrum-4 switch, l1-show command output does not show Eye opening information for an interface port. |
5.9.0-5.9.2 | 5.10.0-5.11.0 |
| 3881789 |
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. |

5.9.0-5.11.0 | |
| 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. | 5.9.0-5.9.2 | 5.10.0-5.11.0 |
| 3861745 |
On UEFI hardware (where the /sys/firmware/efi directory exists), using the update-grub program might generate a /boot/grub/grub.cfg that is incorrect for booting ONIE if the ONIE option is selected on the console while booting. To work around this issue, run mount LABEL=“EFI System” /boot/efi before using update-grub. |
5.9.0-5.11.0 | |
| 3859422 |
On rare occasions when certain events occur, such as changes to the topology in the network, when a bond comes online and directly transits to an STP blocking state, the slave ports might still be in a forwarding state. As a result, traffic is forwarded on a blocked port. | 5.2.0-5.9.1 | 5.9.2-5.11.0 |
| 3855796 |
When configuring a Unicast Master Table for clients, the server addresses must be reachable and the route to the destination must exist. The unicast table can have one directly-connected port for a client. This restriction is only for directly connected ports and doesn’t apply to Unicast Servers on other devices or switches. | 5.9.0-5.11.0 | |
| 3854807 |
When you enable Optimized Multicast Flooding (OMF) and change VLAN configuration, a few ports might carry multicast traffic even when they are not in the MDB or they are not router ports. | 5.6.0-5.9.1 | 5.9.2-5.11.0 |
| 3854800 |
The switch forwards multicast traffic to the CPU when PIM is enabled globally, regardless of the interface configuration. | 5.6.0-5.9.1 | 5.9.2-5.11.0 |

5.8.0-5.9.1 | 5.9.2-5.11.0 |
| 3847439 |
In rare cases on the Spectrum 1 switch where a dual connected host transmits all traffic flows to only one switch in a connected MLAG pair and the host changes behavior to hash all flows to the other MLAG switch, there might be traffic loss if the MAC FDB entry on the original switch ages out. | 5.9.0-5.11.0 | |
| 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. |
5.9.0-5.11.0 | |
| 3835635 |
When adaptive routing is enabled, traffic for non adaptive routing enabled ports and non adaptive routing ECMPs might be routed over all ports in ECMP. Avoid using regular ECMPs with adaptive routing enabled on the switch. | 5.9.0-5.11.0 | |
| 3821643 |
When using SSM and the upstream interface goes away (the source stops sending or the link goes down) the PIMREG interface is added to the outgoing interface list of the S,G and is never removed. As a result, multicast traffic that hits the impacted S,G is forwarded to the CPU and dropped by the switch. | 5.9.0-5.9.1 | 5.9.2-5.11.0 |
| 3819945 |
When you connect an NVIDIA SN4410, SN4700, or SN5600 switch to any Spectrum 1, Spectrum-2, or Spectrum-3 peer switch (with four lanes) using a 4x breakout configuration and the default lanes per port setting, links do not come up. To work around this issue, provide the lanes per port configuration shown below:cumulus@switch:~$ nv set interface |
5.9.0-5.11.0 | |

The terminal monitoring software SecureCRT has a known issue when running on both Windows and Mac systems where it gets “stuck” when monitoring the serial port of the switch as Cumulus Linux boots up. When this occurs, the serial port stops as shown below and SecureCRT is unable to receive any more serial data from the switch (it is able to transmit).Mounting dev-hugepages.mount - Huge Pages File System.. |
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 |
| 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 | |
| 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 |

5.8.0-5.11.0 | |
| 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 |
| 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 | |
| 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. |

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. |
