5.15.0 Release Notes

Open Issues in 5.15.0

Issue IDDescriptionAffectsFixed
4662854
If the DSCP match is configured as “ANY,” the gNMI subscription will not show DSCP as “ANY.” The OpenConfig model supports only integer DSCP values.5.15.0
4648833
Interfaces using PAM4 DAC cables on Spectrum 4 switches and later might not come up after a link flap or reboot if auto-negotiation is not enabled. Auto-negotiation is required for PAM4 DAC cables on these switches
5.15.0
4608614
When setting up SSH keys, you have to run nv config apply twice for the configuration to take effect.5.11.3-5.15.0
4582679
If a node has Suppress Route Advertisement enabled and routes are re-learned; for example, when a peer sends the route again due to route policy changes, or you enable or disable graceful shutdown, not all routes are offloaded, which might cause discrepancies in traffic.5.9.4-5.15.0
4579237
If interface statistics telemetry is running on the switch, an interface_stats_collector core file might generate during statistics collection.5.11.3-5.15.0
4551249
The NVUE service might fail during switch upgrade on Cumulus Linux 5.13.1. To work around this issue, stop the sysmonitor with the sudo systemctl stop sysmonitor command, then upgrade the switch with the nv action upgrade system packages to latest command.5.14.0-5.15.0
4549896
When you try to set a VXLAN with a bridge, you see the error sx_sdk: 22985 [BRIDGE] [ERROR ]: Port(0x200A000D)) already added to a bridge. You can safely ignore this error as it doesn’t impact switch functionality.5.14.0-5.15.0
4547463
When you try to run nv action boot-next commands during optimized image upgrade, the commands time out. This does not necessarily mean an issue occurred; the system might still be executing the action.
To check that the action command completed before going to the next step to reboot the system:
  1. Find the Request ID for the REST API invocation corresponding to the nv action boot-next command by doing a grep for ActionKey.*boot-next in the /var/log/nvued.log file. For example, the value 3 in the Ran Job running ActionKey('@boot-next', ‘/system/image’, (), 3, ((‘partition’, ‘partition1’),)) line indicates the Request ID.
  2. Run the curl -u ‘:<password>’ -X GET https://127.0.0.1:8765/nvue_v1/action/ -k command from the shell to show the status of the action command. If the value of state is action_success, the action command completed successfully. If the value of state is running, the system is still processing. If the value of state is action_error, the system encountered an error.
5.14.0-5.15.0
4535806
After a factory reset, the switch does not clear the /var/tmp directory, which the switch uses for temporary files.5.14.0-5.15.0
4535749
The uc-discards field in the nv show interface counters qos egress-queue-stats command output is actually the number of packets discarded per queue, but it is wrongly interpreted as bytes. To work around this issue, convert the data shown in bytes to packets by multiplying by 1024 if the data is in KB, 1024x1024 if the data is in MB, and 1024x1024x1024 if the data is in GB.5.11.0-5.15.0
4535699
When you configure the RADIUS authentication order with local first and radius second, the RADIUS user is authenticated as a default user name.5.11.3-5.15.0
4531960
The GNMI Subscription to xpath interfaces/interface[name=swp61s0]/state/counters/out-pkts with a high sample interval results in an initial response of zero but in subsequent updates, the value is correct. You do not see this issue when the sample interval is 1 second.5.14.0-5.15.0
4509255
In PTP two-step, the hardware incorrectly modifies the SYNC message correction field.5.12.0-5.15.0
4508830
Cumulus Linux allows you to add bond ports of mismatched speeds (such as 10G and 25G) to the same LACP bond without error and the bond reports UP.5.11.2-5.15.0
4507163
In some cases after a package upgrade with ISSU (warm boot mode), you see continuous errors in the syslog similar to the following:
NOTICE  CORE_ASYNC: Error at pre send callback status [Resource is in use]
5.11.2-5.15.0
4501632
NVIDIA recommends you wait for approximately 60 seconds after running nv config apply before power cycling the switch so that NVUE database has time to sync to the filesystem.5.14.0-5.15.0
4495383
NVUE configuration yaml file translation converts unset commands to set commands because the translation logic expects only set commands.5.13.0-5.15.0
4495231
If the hardware clock date is later than 2038-01-19 03:14:07 UTC, the image might fail to install due to a grub-install failure on the EFI filesystem, which is a VFAT filesystem. As a result, you see the grub prompt immediately after reboot. To work around this issue, reboot from the grub prompt to go into ONIE. From ONIE, use the date command to set a date before 2038-01-19, then run the hwclock –systohc command to add it to the hardware clock. You can then use onie-nos-install to install the image.5.9.0-5.15.0
4475401
External input such as Ctrl+\ might trigger core dumps on the serial console from /bin/login. This behavior is caused by external sources, such as console servers or automation tools, and does not reflect a fault in the operating system. As a potential result, the serial console might become unresponsive.5.14.0-5.15.0
4475111
When you try to convert a layer 3 port that is part of ECMP to a bond member, you might see a failure in the switchd logs. This issue does not have any functional impact.5.11.2-5.15.05.9.4
4440766
When you try to delete a trusted ca key, Cumulus Linux shows an incorrect error message. To remove a trusted ca key, you must unset the key ID, not the key literal.5.13.0-5.15.0
4423248
If you unset an interface static IP address when the interface IP gateway is configured, the nv config apply command fails with an ifreload.service error. To work around this issue, unset both the static IP address and gateway together.5.9.0-5.15.0
4423244
When you enable, then disable adaptive routing, the BGP neighbors might go down because of an unresolved MAC address. To work around this issue, configure another attribute on the interface.5.9.0-5.15.0
4423175
When you configure an API port with a TCP port already in use, the nginx server fails to restart.5.13.0-5.15.0
4413589
A MAC-only EVPN type-2 route is wrongly advertised with the layer 3 VNI label in the BGP NLRI (Network Layer Reachability Information). Although this does not have any functional impact, it is not the desired RFC behavior.5.13.0-5.15.0
4337278
In certain cases, statically configured VXLAN entries age out after a peerlink flap.5.12.0-5.15.0
4329931
In previous releases, Cumulus Linux incorrectly allowed SyncE and PPS In features to be enabled at the same time. Upgrading systems with both features configured using NVUE to 5.12.0 or higher results in a failure to apply the startup configuration as part of the first boot of the upgraded version. To work around the issue, unset one of the features before you upgrade.5.12.0-5.15.0
4309876
When you configure an invalid switch port (swp), NVUE adds the invalid configuration instead of rejecting it. The invalid interface in the configuration does not have any functional impact.5.12.0-5.15.0
4308857
When you use tls_crlcheck in the /etc/nslcd.conf file, the optional nslcd service fails due to a missing library.5.9.2-5.9.3, 5.12.0-5.15.05.9.4
4294156
After you clear the RoCE counters with the nv action clear interface qos roce counters command, the buffer-max-usage counters in the nv show interface qos roce counters command output do not show updated (cleared) values.5.12.0-5.15.0
4277042
On the NVIDIA SN5600 switch, you see low power alarms immediately after a reboot. The alarms disappear after showing up initially. Certain modules typically show low power alarms on initialization. No action is needed.5.12.0-5.15.0
4249096
Binary upgrade from Cumulus Linux 4.3.1 to 5.12.0 and later is not supported. To work around this issue, perform a binary upgrade from Cumulus Linux 4.3.1 to 5.9.0, then perform a binary upgrade from Cumulus Linux 5.9.0 to 5.12.0 or later.5.12.0-5.15.0
4236419
On the Spectrum-3 switch, the PTP offset for 25GbE fluctuates within a range of plus or minus 50 nanoseconds beyond the expected values.5.12.0-5.15.0
4214678
Changes to open telemetry configuration or export states restarts the telemetry service and resets all health metrics.5.12.0-5.15.0
4177067
When performing a package upgrade, nslcd installation might open an interactive dialog to configure nslcd.conf .
To avoid this interactive dialog, set the DEBIAN_FRONTEND environment variable to noninteractive. For example:
cumulus@switch:~$ sudo apt-get update
cumulus@switch:~$ sudo DEBIAN_FRONTEND=noninteractive apt-get -y -o “Dpkg::Options::=–force-confdef” -o “Dpkg::Options::=–force-confold” upgrade
5.11.0-5.15.0
4154839
When you run certain SDK commands (such as sudo sx_api_port_counter_dump_all.py or sx_api_fdb_dump) first as the cumulus user, then with sudo, you see the following error:
PermissionError: Errno 13] Permission denied: ‘/tmp/python_err_log.txt’

To resolve this issue, run the rm -rf /tmp/python_err_log.txt command.
5.11.0-5.15.0
4142857
The switch drops PTP packets received with extra ethernet padding and you see syslog [ptp4l.ERR] messages.5.10.0-5.15.0
4139511
When you generate the cl-support file on the Spectrum-4 switch, the following messages appear on the serial console. You can safely ignore this issue.
[ 1903.595131] mlxsw_minimal 2-0048: Could not acquire lock
[ 1903.601089] mlxsw_minimal 2-0048: Reg cmd access failed (reg_id=900a(mtmp),type=query)
[ 1903.609961] hwmon hwmon28: Failed to query module temperature thresholds
[ 1903.846724] mlxsw_minimal 2-0048: Could not acquire lock
[ 1903.852689] mlxsw_minimal 2-0048: Reg cmd access failed (reg_id=900a(mtmp),type=query)
[ 1903.861573] hwmon hwmon28: Failed to query module temperature
5.11.0-5.15.0
4134447
The journal logs might include the error message ERR kernel: [ 7.453789] usb usb2-port2: connect-debounce failed. You can safely ignore this log message.5.11.0-5.15.0
4129757
If you include a comma in the BGP community list, extended community list, or large community list regex expression of a routing policy, you see error messages and FRR reload fails. Make sure the regex expression does not contain a comma.
For example, instead of ^65550:([0-9]{1,2}|[1-9][1-9]):.$, specify ^65550:([0-9]|[0-9][0-9]):.$ and instead of ^65550:([0-4]{1,2}|[7-9][8-9]):.$, specify ^65550:([0-4]|[0-4][0-4]|[7-9][8-9]):.$.
5.11.0-5.15.0
4124376
The SN3700C-S, SN5400, and SN5600 secure boot switch running Cumulus Linux 5.11.0 or later boots with shim 15.8 that adds entries to the SBAT revocations to prevent the switch from booting shim 15.7 or earlier (included in Cumulus Linux 5.10 and earlier).
To downgrade a secure boot switch from Cumulus Linux 5.11.0 or later, or to recover a downgraded switch that does not boot, follow the steps in Downgrade a Secure Boot Switch.
5.11.0-5.15.0
4118970
When running PTP, the performance for 100Gx2 and 400Gx8 can have a high offset in up to 1.5% of the sampling.5.11.0-5.15.0
4105127
Any sFlow configuration changes that require an hsflowd restart are operational only after an initial delay of 60 seconds.5.11.0-5.15.0
4100629
NVUE show command outputs show LLDP neighbor changes only after the LLDP update frequency multiplied by the hold time.5.11.0-5.15.0
4082210
When you change the CPU resource limit with the nv set service control rsyslog resource-limit cpu command, the rsyslog agent does not start. To work around this issue, increase the CPU resource limit, then restart the service manually.5.11.0-5.15.0
4077921
You cannot use package upgrade to upgrade from Cumulus Linux 5.9.2 to Cumulus Linux 5.10.1 or later. You must install the Cumulus Linux image instead.5.10.1-5.15.0
4049213
When there are routes that point to a single next hop, an ECMP entry is created in the SDK. After the single next hop from the route is removed, the ECMP entry might stay in the SDK until the time the next hop is present in the kernel.5.9.2-5.15.0
4047798
Packet distribution based on ECMP hash is not working for VXLAN on top of rack switches where it is encapped. To work around this issue, enable lag hashing with gtp-teid to distribute the VXLAN encapped packets across egress interfaces.5.10.0-5.15.0
4030380
When you roll back interface configuration to the default setting with the nv unset interface command, NVUE removes the complete entry for the interface from the /etc/network/interface file, and puts the interface in admin down. As a result, you cannot configure FEC on the interface at the lower layers.5.10.0-5.15.0
4005422
When you upgrade Cumulus Linux 5.9.1 to Cumulus Linux 5.10 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.5.10.0-5.15.0
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.5.10.0-5.15.0
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.5.10.0-5.15.0
3948068
On the SN3700 and SN3700c switch, the nv show platform environment voltage command output shows a failed state for the PSU-n-12V-RAIL-OUT sensors. This is a known hardware limitation that cannot be corrected by the PSU vendor.5.10.0-5.15.0
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.
5.9.0-5.15.0
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.5.10.0-5.15.0
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.
5.9.0-5.15.0
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.
5.9.0-5.15.0
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.5.9.0-5.15.0
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.5.9.0-5.15.0
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.5.9.0-5.15.0
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.5.9.0-5.15.0
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  link breakout 4x lanes-per-port 1
5.9.0-5.15.0
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..
Mounting dev-mqueue.mount
5.9.0-5.15.0
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.5.8.0-5.15.0
3773177
When you try to upgrade a switch from Cumulus Linux before 5.6.0 with package upgrade, you might 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
cumulus@switch:~$ sudo apt install ./cumulus-archive-keyring_4-cl5.6.0u5_all.deb
cumulus@switch:~$ sudo apt update
cumulus@switch:~$ sudo apt upgrade
4.0.0-4.4.5, 5.0.0-5.15.0
3771168
When you perform an ISSU upgrade on a Spectrum 1 switch, the switchd service might crash.5.8.0-5.15.0
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.5.7.0-5.15.0
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.5.7.0-5.15.0
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 inbound control-plane.5.7.0-5.15.0
3591918
The nv action disconnect system aaa user command does not clear all open sessions. To work around this issue, run the command as many times as the number of sessions.5.6.0-5.15.0
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:
  • Use Ixia IxOS version 9.37 with HF002156, or version 9.39 or later.
  • Use the DAC cable on ports 10 through 50.
  • Use NVIDIA cables with the recommended firmware revision.
  • Configure AN on the Cumulus Linux switch and AN/LT on Ixia.

To work around this issue when using fiber cables:
  • Configure 800g/Force.
  • Use the recommended NVIDIA optical adapters.
5.6.0-5.15.0
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.5.5.0-5.15.0
3540510
400Gx8 ports only support traffic line rate with packets that are larger than 172 bytes.5.6.0-5.15.0
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.5.6.0-5.15.0
3497622
When you remove PSUs, then plug them back in, you might experience traffic loss and some ports might be in a down state.5.6.0-5.15.0
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.5.6.0-5.15.0
3444490
Migration from ONYX to Cumulus Linux is supported and tested with ONYX version 3.10.4302 GA only.5.6.0-5.15.0
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.5.5.0-5.15.0
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.5.5.0-5.15.0
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.5.0.0-5.15.0
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, 5.0.0-5.15.0
3414866
Each VLAN is represented as a bitmap on the underlying port and when you add multiple VLANs together, Cumulus Linux iterates over the existing ones and updates the diff. However, in few corner cases, the same bitmap might be repeated again causing the following error.
sx_sdk: 22985 [BRIDGE] [ERROR  ]: Port(0x200A000D)) already added to a bridge

You can ignore this error; it has no impact on switch functionality.
5.6.0-5.15.0
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.5.4.0-5.15.0
3347538
When connecting NVIDIA-to-NVIDIA in PAM4, you must enable auto-negotiation.5.4.0-5.15.0
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.5.4.0-5.15.0
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.5.4.0-5.15.0
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, 5.0.0-5.15.0
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.5.4.0-5.15.0
3253218

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

You might see convergence degradation in a remote link failure scenario due to very chatty LTTNG traces that add logging overhead.5.14.0
4605303
The downstream VNI software VXLAN encapsulation path does not derive the source IP address of the outer IP header properly. Instead of using the defined vxlan-local-tunnelip under the loopback interface, it uses the underlay interface on which the packet egresses the VTEP. In a mixed vendor environment, this might lead to a drop on the decapsulating VTEP if it is not an Nvidia Cumulus Linux switch. To work around this issue, use symmetric VNI configuration instead of downstream VNI or use downstream VNI with an unnumbered underlay.5.13.0-5.14.0
