5.10.1 Release Notes
Open Issues in 5.10.1
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4200961 |
If you use a bridge name that isn’t br_default, NVUE generates incorrect ptp4l.conf files. |
5.10.0-5.11.0 | |
| 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 | |
| 4175695 |
If all of the neighbors returned in the nv show vrf command output have no address-family configuration, you see an internal error when the nested table in the output is being rendered. |
5.10.0-5.11.0 | |
| 4175217 |
When there is a large number of discontiguous VTEP to VLAN mappings, switchd crashes with a Netlink error similar to the following:
|
5.10.1-5.11.0 | |
| 4173498 |
After network churn, the watchfrr process might restart FRR because zebra is unresponsive. |
5.9.1-5.11.0 | |
| 4170628 |
If you use a bridge name that isn’t br_default, NVUE generates incorrect ptp4l.conf files. |
5.10.0-5.11.0 | |
| 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 | |
| 4159554 |
When you configure EVPN multihoming with more than one ESI bond member, you might see intermediate traffic loss. | 5.9.1-5.11.0 | |
| 4142857 |
The switch drops PTP packets received with extra ethernet padding and you see syslog [ptp4l.ERR] messages. |
5.10.0-5.11.0 | |
| 4137492 |
Accessing NVIDIA Spectrum-4 SPICE from multiple applications to the same path in parallel might cause a kernel crash. | 5.10.1 | 5.11.0 |
| 4135919 |
You might experience a memory leak in ospfd when processing next hops due to network changes. |
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 |
| 4127636 |
Multicast traffic continues to egress an interface that leaves the group. Logs and multicast data show that the IGMP group is deleted but the OIF is still listed. | 5.10.0-5.10.1 | 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 |
| 4119696 |
If you run nv set commands after you perform an upgrade but before a reboot, NVUE creates a revision based off the pre-upgrade version. After reboot, the revision contains pre-upgrade data that might cause it to fail during config apply. To work around this issue, detach the stale revision after upgrade with the nv config detach command. |
5.10.0-5.10.1 | 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 | |
| 4100170 |
The NVUE Service fails to start after an upgrade from Cumulus Linux 5.9 to Cumulus Linux 5.10 because of a corrupted database. | 5.10.0-5.11.0 | |
| 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 | |
| 4086136 |
If a Cumulus Linux 5.9.1 switch has an nv set interface configuration with an empty value, when you upgrade to Cumulus Linux 5.10, NVUE cannot apply the configuration and shows an Invalid config message. |
5.10.0-5.10.1 | 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 | |
| 4077921 |
You cannot use package upgrade to upgrade from Cumulus Linux 5.9.2 to Cumulus Linux 5.10.1. You must install the Cumulus Linux 5.10.1 image. | 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 |
| 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 |
| 4061534 |
When you remove a secondary OTLP collector, there is a telemetry spike and existing connections with OTLP exporters reset. When new connections with the OTLP collector re-establish, the server experiences a high CPU and memory leak, which can bring down the telemetry collection service. | 5.10.0-5.10.1 | 5.11.0 |
| 4050835 |
The NVUE Service fails to start after an upgrade from Cumulus Linux 5.9 to Cumulus Linux 5.10 because of a corrupted database. | 5.10.0-5.10.1 | 5.11.0 |
| 4050801 |
When configuring telemetry for interface statistics with ranges or lists, the lists and ranges do not expand correctly in the configuration and the configuration is rejected. Configuration example:cumulus@leaf01:~$ nv set system telemetry interface-stats ingress-buffer priority-group 1-6 You see the following log errors: interface_stats: [ERROR] interface_stats_collector.py:_parse_conf_file:201 — Configured ingress-priority-group 0-6 is not an integer |
5.10.0-5.10.1 | 5.11.0 |
| 4047798 |
Packet distribution based on ECMP hash is not working for VXLAN at TOR switches where it is encapped. To balance traffic between egress ports, you can use lag or ECMP hash. To enable traffic distribution in this use case, lag hashing as well needed to be enabled. | 5.10.0-5.11.0 | |
| 4037315 |
NVUE fails to enforce the password length limitation of 512 characters or fewer. | 5.10.0-5.10.1 | 5.11.0 |
| 4023318 |
If you run nv set commands after you perform an upgrade but before a reboot, NVUE creates a revision based off the pre-upgrade version. After reboot, the revision contains pre-upgrade data that might cause it to fail during config apply. To work around this issue, detach the stale revision after upgrade with the nv config detach command. |
5.10.0-5.10.1 | 5.11.0 |
| 4022906 |
If you use NVUE to configure a bond, apply a port mirror on the bond, then run the nv config apply command, the validation fails.To work around this issue, configure the bond with a separate nv config apply command before you configure the port mirror on the bond. |
5.10.0-5.10.1 | 5.11.0 |
| 4005422 |
When you upgrade Cumulus Linux 5.9.1 to Cumulus Linux 5.9.2 or later with package upgrade, the NTP service stops. To restart the NTP service, enable, then restart the service in the VRF in which it was running with the systemctl enable ntpsec@ and systemctl restart ntpsec@ commands. |
5.10.0-5.11.0 | |
| 4004898 |
When you configure the SNMP server listening address to a VRF that has no interfaces, snmp.service fails.To recover from the failure, set the SNMP server listening address back to the VRF that has interfaces. If you really want to move the SNMP server to the VRF with no interfaces, assign an interface to the VRF and move the SNMP server to the VRF. |
5.10.0-5.11.0 | |
| 3990135 |
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 | |
| 3985682 |
On Spectrum-4 switches, multicast flows containing packets smaller than 512 bytes might not reach full line rate. Cumulus Linux supports 512 byte and larger multicast packets. | 5.10.0-5.11.0 | |
| 3966312 |
When connecting the SN5xxx switch to third party test equipment (such as IXIA) using copper cables at 100GbE, 200GbE, 400GbE, or 800GbE, links do not come up. | 5.10.0-5.11.0 | |
| 3928905 |
The nv show interface commands show RX and TX Power values from the wrong lanes on breakout ports. |
5.8.0-5.9.1, 5.10.0-5.11.0 | 5.9.2 |
| 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 | |
| 3879809 |
What Just Happened (WJH) does not work on Spectrum-4 switches. | 5.9.0-5.11.0 | |
| 3879717 |
Running snmpwalk on the switch with the management IP address does not work. To work around this issue, use the localhost option (snmpwalk -v 2c -c public28 localhost 1.3.6.1.2.1.14) or create a control plane ACL whitelist rule. |
5.10.0-5.11.0 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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:
To work around this issue when using fiber 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 | |
| 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. |

If you use a bridge name that isn’t br_default, NVUE generates incorrect ptp4l.conf files. |
5.10.0-5.11.0 | |
| 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. |

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. |

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. |

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. |

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 |

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 |

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 |

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 |

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 |

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 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 |

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. |

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. |

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. |

When you enable a service in the management VRF, systemctl issues a warning similar to the following:Warning: The unit file, source configuration file or drop-ins of ntp@mgmt.service changed on disk. Run ‘systemctl daemon-reload’ to reload unitYou can safely ignore this warning. |
