Open Issues in 5.11.0
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4309870 |
Due to unsupported EVPN BUM replication configuration (a mix of PIM and HER modes), a resource leak can occur. | 5.11.0-5.12.1 | |
| 4309850 |
The management interface on the NVIDIA SN2010 and SN2100 switch negotiates to 100 Mbps instead of 1 Gbps. | 5.11.0-5.12.1 | |
| 4298583 |
The Spectrum-4 switch reports a Modules DataPath FSM fault in logs when the link fails at polling. |
5.10.1-5.12.0 | 5.12.1 |
| 4286417 |
When sending control packets which have in their TX base header system target port 259-1023 (above cap_max_system_ports and below cap_ports - which is used for LAG forwarding), a health event of a fatal cause will occur in the switch. | 5.11.0-5.12.0 | 5.12.1 |
| 4281099 |
When you bring STP down, then up on the primary MLAG peer, the STP state machine restarts and the peerlink operational edge resets. As a result, the secondary MLAG peer ends up in an STP discarding state. To work around this issue, restart the clagd service. |
5.8.0-5.11.0 | 5.12.0-5.12.1 |
| 4277143 |
After a factory reset with the nv action reset system factory-default force command, RADIUS does not fully reset; the radius-cmd-acct package is not installed correctly and includes missing files. In addition, /etc/pam.d/common-auth is incorrect. |
5.11.0 | 5.12.0-5.12.1 |
| 4271232 |
A Python version change removed the encoding argument parameter of the json loads function, which causes an exception. | 5.11.0-5.12.1 | |
| 4271229 |
After rebooting the spine switch in an EVPN multihoming configuration, the BGP EVPN Type-2 entry is missing, which causes flooding and duplicates in the fabric. To work around this issue, flush the IP neighbor entries with the sudo ip neigh flush x.x.x.x command. |
5.9.1-5.11.0 | 5.12.0-5.12.1 |
| 4271216 |
NVUE overwrites the MOTD file during NVUE configuration with no option to ignore it |
5.11.0-5.12.1 | |
| 4271215 |
NVUE overwrites the MOTD file during NVUE configuration with no option to ignore it |
5.11.0-5.12.1 | |
| 4271213 |
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. |
5.9.2-5.12.1 | |
| 4271212 |
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 | 5.12.0-5.12.1 |
| 4271207 |
Stale Next Hop Groups are left in the kernel resulting in polarized Adaptive Routing traffic. | 5.10.1-5.11.0 | 5.12.0-5.12.1 |
| 4271203 |
When the STP state goes down, then back up on the primary MLAG peer, the peerlink state is not updated correctly in mstpd. |
5.8.0-5.11.0 | 5.12.0-5.12.1 |
| 4270957 |
Optimized (two partition) upgrade from Cumulus Linux 5.11.0 requires approximately 2.4 Gbytes of free space in /var after downloading the image with NVUE commands instead of 1.6 Gbytes of free space. Upgrade needs the extra space for an additional copy of the downloaded image in /var . |
5.11.0 | 5.12.0-5.12.1 |
| 4264726 |
When you configure EVPN multihoming with more than one ESI bond member, you might see intermediate traffic loss. | 5.9.1-5.11.0 | 5.12.0-5.12.1 |
| 4260019 |
NVUE prevents you from setting the IPv6 RA lifetime to 0 (zero). Use vtysh mode to apply the setting. | 5.11.0 | 5.12.0-5.12.1 |
| 4260016 |
When you enable SNMP, Cumulus Linux enables and creates an agentx user called debian-snmp automatically for FRR. As a result, TACACS sends log messages similar to the following:«sudo: nss_tacplus: TACACS+ server 10.23.1.0:49 read failed (-3) for user Debian-snmp: Success» To work around this issue, manually add the debian-snmp user to the TACACS configuration exclude_users list so that TACACS ignores this user. |
5.11.0 | 5.12.0-5.12.1 |
| 4260014 |
When you configure the SPAN port mirror truncate size to a value greater than four 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 | 5.12.0-5.12.1 |
| 4260012 |
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 | 5.12.0-5.12.1 |
| 4260011 |
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. |
5.10.0-5.12.1 | |
| 4259980 |
After you reboot the switch, the ifplugd.service fails to start monitoring the interface. | 5.8.0-5.11.0 | 5.12.0-5.12.1 |
| 4251315 |
When you enable NAT dynamic mode and NAT rules with NVUE in a single commit, you see the error error: hw sync failed (Dynamic NAT is not enabled. Ignoring rules..). To work around this issue, enable dynamic NAT with NVUE in one commit, then add NAT ACL rules in a subsequent commit. |
5.11.0 | 5.12.0-5.12.1 |
| 4248634 |
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 | 5.12.0-5.12.1 |
| 4248626 |
The nv show system ztp command might report an error when you use a system local that represents time differently from %a %b %d %H:%M:%S %Y %Z. |
5.11.0 | 5.12.0-5.12.1 |
| 4246859 |
The nv show service ntp command displays the peers that are discovered together with the configured NTP servers instead of displaying only the NTP configuration. As a result, the “applied” and “operational” columns have different values, which causes confusion. |
5.11.0-5.12.1 | |
| 4246858 |
The nv show service ntp command shows the peers that are discovered together with the configured NTP servers instead of displaying only the NTP configuration. As a result, the applied and operational columns have different values, which causes confusion. |
5.11.0 | 5.12.0-5.12.1 |
| 4245856 |
The nv show platform transceiver command sometimes does not show transceiver data for layer 3 Dot1q subinterfaces (such as swp2.10). To work around this issue, run the ethtool -m command. |
5.11.0 | 5.12.0-5.12.1 |
| 4245853 |
NVUE Rest API calls that are authenticated with TACACS on the switch append unnecessary database entries to the /run/tacacs_clent_map file, which increases the file size. Over time, this increases the TACACS login authentication time, resulting in delayed login authentication.To work around this issue, delete the tacacs_client_map file with the sudo rm rf /run/tacacs_client_map command. |
5.11.0 | 5.12.0-5.12.1 |

Over time, this increases the TACACS login authentication time, resulting in delayed login authentication.To work around this issue, delete the tacacs_client_map file with the sudo rm rf /run/tacacs_client_map command. |
5.11.0-5.12.1 | |
| 4245850 |
When using the REST API to move a port from one bridge to another bridge, the bridge-vlan configuration on the port might be programmed incorrectly. To resolve the issue, run the ifreload -a command. |
5.9.1-5.11.0 | 5.12.0-5.12.1 |
| 4245819 |
A Python version change removed the encoding argument parameter of the json loads function, which causes an exception. | 5.11.0 | 5.12.0-5.12.1 |
| 4223451 |
When you change the VRR MAC address, switchd crashes. This occurs because deleting an old VRR MAC address triggers a neighbor update that changes the ECMP container resolution, which results in route entry updatesThis happens in async mode, where the end notification expected after an end of operation is missing. |
5.9.2-5.11.0 | 5.12.0-5.12.1 |
| 4223450 |
Under unique hardware failure conditions, when the ASIC temperature sensor read fails repeatedly, the fans are set to twenty percent, which might not be high enough to maintain proper ASIC cooling, resulting in a thermal shutdown. | 5.11.0 | 5.12.0-5.12.1 |
| 4220393 |
The default GRUB timeout style changed from menu to countdown. When booting, a countdown displays on the console and you can use the escape key to break out of the countdown and show the GRUB menu. This reduces the chance of console noise halting the reboot process. If you press the escape key twice, you might go to the GRUB command line. In this case, type normal to get back to the GRUB menu or reboot to reboot the switch. |
5.11.0 | 5.12.0-5.12.1 |
| 4209429 |
Unreachable or reject routes might not get installed into the SDK. | 5.11.0 | 5.12.0-5.12.1 |
| 4205060 |
Debian 12 does not support LDAP SSL CRL check. Cumulus Linux now uses CRL file. | 5.11.0 | 5.12.0-5.12.1 |
| 4200961 |
If you use a bridge name other than br_default, PTP neighbors fail to establish because the PTP packets are sourced from an unexpected IP address.To work around this issue, configure the base-interface for the VLAN interface with the nv set interface command. |
5.10.0-5.11.0 | 5.12.0-5.12.1 |
| 4200952 |
Configuring the listening-address for the SNMP server fails for IP addresses associated with VRFs other than the management VRF. | 5.11.0-5.12.1 | |
| 4199125 |
ZTP scripts return an error due to incorrect ASCI to UTF-8 conversion. | 5.11.0 | 5.12.0-5.12.1 |
| 4198683 |

5.9.2-5.11.0 | 5.12.0-5.12.1 |
| 4183214 |
If you upgrade the switch from Cumulus Linux 5.9.x or 5.10.x with package upgrade and Radius is enabled, you see configuration and commit errors. To avoid this issue, either disable Radius during package upgrade or disable Radius before package upgrade with the sudo adduser –system –group –home /run/nslcd –no-create-home –gecos ‘nslcd name service LDAP connection daemon’ nslcd command. |
5.11.0 | 5.12.0-5.12.1 |
| 4178578 |
An unexpected thermal reboot occurs due to an incorrect firmware status in the i2c driver. | 5.10.0-5.12.1 | |
| 4177067 |
When doing a package upgrade from CL5.9 or CL5.10 to CL5.11, the installation of nslcd 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 |
5.11.0-5.12.1 | |
| 4176931 |
The nv show platform firmware command results in a Python traceback and takes a long time to complete because the VX image does not support the smartctl utility. |
5.11.0 | 5.12.0-5.12.1 |
| 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 | 5.12.0-5.12.1 |
| 4174646 |
On the NVIDIA SN5400 and SN5600 switch, the fans might run at full speed when it is not necessary. | 5.10.1-5.11.0 | 5.12.0-5.12.1 |
| 4173602 |
On the Spectrum-4 switch, switchd might crash with the following log message:CRIT Restarting switchd to recover from SDK health event: FW Long Command |
5.10.1-5.11.0 | 5.12.0-5.12.1 |
| 4173498 |
After network churn, the watchfrr process might restart FRR because zebra is unresponsive. |
5.9.1-5.12.1 | |
| 4156409 |
When you enable the BGP PIC next hop group per source option:
|
5.11.0-5.12.1 | |
| 4154839 |
When you run certain SDK commands (such as sudo sx_api_port_counter_dump_all.py or sx_api_fdb_dump etc) 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. |
5.11.0-5.12.1 | |
| 4142857 |
The switch drops PTP packets received with extra ethernet padding and you see syslog [ptp4l.ERR] messages. |
5.10.0-5.12.1 | |
| 4139511 |
When you generate the cl-support file on the Spectrum-4 switch, the following messages appear on the serial console. The issue is harmless.[ 1903.595131] mlxsw_minimal 2-0048: Could not acquire lock |
5.11.0-5.12.1 | |
| 4134447 |
The journal logs might include the error message ERR kernel: [ 7.453789] usb usb2-port2: connect-debounce failed. This log message has no functionality impact and can be safely ignored. |
5.11.0-5.12.1 | |
| 4134174 |
If you configure a route map by attaching it to a specific protocol, then you detach it from that protocol, if you then attach the same route map to all protocols, then detach it from all protocols, Cumulus Linux deletes routes from the forwarding table. To work around this issue, either attach the route map to all protocols or attach the route map to each protocol you want to use. For example, to attach the route map to all protocols, run the nv set vrf command. To attach the route map to each protocol you want to use, run the nv set vrf command. |
5.11.0 | 5.12.0-5.12.1 |
| 4130022 |
LDAP does not support per-command authorization. | 5.11.0 | 5.12.0-5.12.1 |
| 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]):.$, specify ^65550:([0-4]|[0-4][0-4]|[7-9][8-9]):.$. |
5.11.0-5.12.1 | |
| 4128952 |
Cumulus Linux does not support LDAP over IPv6. | 5.11.0-5.12.1 | |
| 4127932 |
After you run the nv action install system image command or the cl-image-upgrade -u command, if you run the command a second time to upgrade to a different image, the upgrade might fail because there are leftover /var/install/sys mounts. To resolve this issue, either reboot before you retry image upgrade or run the following commands :cumulus@switch:~$ sudo mount –make-rslave /var/installer/sys |
5.11.0 | 5.12.0-5.12.1 |
| 4127315 |
If you set BGP community-advertise large to off with NVUE, large communities are still sent to BGP peers. To resolve this issue, NVUE has changed the default value of community-advertise large from off to on. | 5.11.0 | 5.12.0-5.12.1 |
| 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. |
5.11.0-5.12.1 | |
| 4122591 |
The NVUE nv set system aaa ldap ssl ca-list command shows the following error if you use the string option:Error: At ca-list: ‘/etc/ssl/certs/ca-cert.crt’ is not one of [‘default’, ‘none’] |
5.11.0 | 5.12.0-5.12.1 |
| 4118970 |
When running PTP, the performance for 100Gx2 and 400Gx8 can have a high offset in up to 1.5% of the sampling. | 5.11.0-5.12.1 | |
| 4105127 |
Any sFlow configuration changes that require an hsflowd restart are operational only after an initial delay of 60 seconds. |
5.11.0-5.12.1 | |
| 4101560 |
The nv set vrf command only works if you restart FRR after you run the command. To work around this issue, attach the route map to each needed protocol; for example, run the nv set vrf command. |
5.11.0 | 5.12.0-5.12.1 |
| 4101027 |
After you add a VLAN to a bridge member port, you might experience a few seconds of VXLAN traffic loss. | 5.7.0-5.12.1 | |
| 4100629 |
NVUE show command outputs show LLDP neighbor changes only after the LLDP update frequency multiplied by the hold time. | 5.11.0-5.12.1 | |
| 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. | 5.10.0-5.12.1 | |
| 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. |
5.8.0-5.12.1 | |
| 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. |
5.11.0-5.12.1 | |
| 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. | 5.10.1-5.12.1 | |
| 4052578 |
When you perform a binary upgrade from Cumulus Linux 5.8 or earlier to 5.9.0 or later with a pre-staged startup.yaml file, the cumulus user password is reset to the default password because there is no default startup.yaml file present in 5.8.0 or earlier. To work around this issue, generate the startup.yaml file from the existing NVUE configuration. |
5.9.2-5.11.0 | 5.12.0-5.12.1 |
| 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 VXLAN encapped packets across egress interfaces on the top of rack switches. | 5.10.0-5.12.1 | |
| 4030380 |
When you rollback 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 can’t configure FEC on the interface at the lower layers. |
5.10.0-5.12.1 | |
| 4019256 |
If you change the switch hostname, the histogram data producer service restarts. | 5.10.0-5.12.1 | |
| 4005422 |
When you upgrade Cumulus Linux 5.9.1 to Cumulus Linux 5.10 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. |
5.10.0-5.12.1 | |
| 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. | 5.10.0-5.12.1 | |
| 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. | 5.10.0-5.12.1 | |
| 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. |
5.9.0-5.12.1 | |
| 3879809 |
What Just Happened (WJH) does not work on Spectrum-4 switches. | 5.9.0-5.12.1 | |
| 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. |
5.10.0-5.12.1 | |
| 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. |
5.9.0-5.12.1 | |
| 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. |
5.9.0-5.12.1 | |
| 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. |
5.9.0-5.12.1 | |
| 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. |
5.9.0-5.12.1 | |
| 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. | 5.9.0-5.12.1 | |
| 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. | 5.9.0-5.12.1 | |
| 3844670 |
When you configure TACACS with NVUE or merge in an NVUE configuration file including TACACS configuration with the nv config patch command, you see an unrecoverable error when running additional NVUE commands. To work around this issue, restart the NVUE service with the systemctl restart nvued.service command. |
5.9.0-5.11.0 | 5.12.0-5.12.1 |
| 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. | 5.9.0-5.12.1 | |
| 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 |
5.9.0-5.12.1 | |
| 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.. |

5.8.0-5.12.1 | |
| 3677533 |
Due to resource constraints on the Spectrum 1 switch, staticd performance drops and takes longer to read static routes compared to the time BGP takes to complete a graceful restart and advertise routes and EOR to its helpers. As a result, static routes are advertised after the EOR is sent to graceful restart helpers, which delete the stale static routes and relearn them after receiving the EOR from the restarting node. Temporary traffic loss might occur. |
