Open Issues in 5.11.0
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 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 | |
| 4170628 | If you use a bridge name that isn’t br_default, NVUE generates incorrect ptp4l.conf files. | 5.10.0-5.11.0 | |
| 4142857 | The switch drops PTP packets received with extra ethernet padding and you see syslog [ptp4l.ERR] messages. | 5.10.0-5.11.0 | |
| 4135543 | Under certain rare scenarios, the operational status of a switch port interface shows as UP after you administratively configure it to stay down with the nv set interface command. To clear this condition, toggle the admin status on the interface once. | 5.11.0 | |
| 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 | |
| 4130022 | When you configure LDAP authentication, applying NVUE configuration might take a long time if the LDAP server is slow. To avoid this delay, ensure that local is before ldap in the authentication order. | 5.11.0 | |
| 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. | 5.11.0 | |
| 4128952 | Cumulus Linux does not support LDAP over IPv6. | 5.11.0 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 4007590 | 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | |
| 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 | 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 | |
| 2972540 | With RADIUS enabled for user shell authentication, there might be a delay in local user authentication for non cumulus user accounts. | 5.0.0-5.11.0 | |
| 2964279 | When a VNI flaps, an incorrect list of layer 2 VNIs are associated with a layer 3 VNI. The NCLU net show evpn vni detail command output shows duplicate layer 2 VNIs under a layer 3 VNI. | 3.7.15, 4.4.2-4.4.5, 5.0.0-5.11.0 | 3.7.16 |
| 2951110 | The net show time ntp servers command does not show any output with the management VRF. | 3.7.15-3.7.16, 4.1.1-4.4.5, 5.0.0-5.11.0 | |
| 2904450 | When you run the ethtool -m or the l1-show command, the 400G interface optical values do not show. | 4.4.0-4.4.5, 5.0.0-5.11.0 | |
| 2891255 | CVE-2021-39925: Buffer overflow in the Bluetooth SDP dissector in Wireshark 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17 allows denial of service via packet injection or crafted capture file. Vulnerable: <= 2.6.20-0+deb10u1 Fixed: 2.6.20-0+deb10u2 | 4.0.0-4.4.1, 5.0.0-5.11.0 | 4.4.2-4.4.5 |
| 2890681 | CVE-2021-42771: relative path traversal in Babel, a set of tools for internationalising Python applications, could result in the execution of arbitrary code Vulnerable: 2.6.0+dfsg.1-1Fixed: 2.6.0+dfsg.1-1+deb10u1 | 4.0.0-4.4.1, 5.0.0-5.11.0 | 4.4.2-4.4.5 |
| 2867042 | When connecting the NVIDIA SN4600 switch to another NVIDIA Spectrum switch, you must use auto-negotiation mode (not force mode); otherwise the switch might use the wrong Tx configuration. | 5.0.0-5.11.0 | |
| 2823307 | Cumuls Linux does not support a bond with more than 64 ports. Any configuration with more than 64 ports in a bond changes all ports to down when you apply the configuration. | 5.0.0-5.11.0 | |
| 2736108 | When you change the VRRP advertisement interval on the master, the master advertisement interval field in the show vrrp command output does not show the updated value. | 4.4.0-4.4.5, 5.0.0-5.11.0 | |
| 2684925 | The NVUE nv show vrf default router bgp peer command produces a 404 not found error. | 4.4.0-4.4.5, 5.0.0-5.11.0 | |
| 2671652 | In VXLAN routing environments, you might experience sub-optimal route convergence delays (longer than five seconds) when a prefix transitions to a new ECMP next-hop group. This condition might occur when a VTEP loses ECMP routes through all uplink peerings, then installs the routes through a different path, such as an MLAG peerlink. | 4.4.0-4.4.5, 5.5.0-5.11.0 |
Fixed Issues in 5.11.0
| Issue ID | Description | Affects |
|---|---|---|
| 4137492 | Accessing NVIDIA Spectrum-4 SPICE from multiple applications to the same path in parallel might cause a kernel crash. | 5.10.1 |
| 4135919 | You might experience a memory leak in ospfd when processing next hops due to network changes. | 5.9.1-5.10.1 |
| 4130139 | If the LDAP server becomes unreachable while an LDAP user is logged on, NVUE nv set and nv show commands result in traceback messages. | |
| 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 |
| 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 |
| 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 |
| 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. | 5.8.0-5.10.1 |
| 4111688 | The ethtool -m command output for certain QSFP-DD and OSFP optical modules does not report the alarm status of the various channels correctly. This is an issue with ethtool that has been fixed and upstreamed. | |
| 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. | 5.9.1-5.10.1 |
| 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 |
| 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. | 5.9.1-5.10.1 |
| 4089469 | When you apply interface configuration at the same time as VRF based services (such as the DHCP service for a VRF), the VRF based service does not become fully operational because the service is not receiving protocol packets. To work around this issue, first apply the interface configuration, then apply the configuration for the VRF based service. | |
| 4087368 | On the NVIDIA SN2201 switch, the nv show platform firmware SSD command shows the error The requested item does not exist and the nv show platform firmware command does not show SSD details. | |
| 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 |
| 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. | 5.9.1-5.10.1 |
| 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 |
| 4066219 | Some STP interfaces might remain in a blocking state when there are large numbers of dis-contiguous VLANs enabled on a port. | 5.8.0-5.10.1 |
| 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 |
| 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 |
| 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 |
| 4037315 | NVUE fails to enforce the password length limitation of 512 characters or fewer. | 5.10.0-5.10.1 |
| 4037224 | ASIC monitoring histogram collection might not work because of a crash in the asic-monitor service. To work around this issue, see the Release Considerations section of the What’s New. | 5.10.0 |
| 4034329 | After network churn, the watchfrr process might restart FRR because zebra is unresponsive. | 5.9.1-5.10.0 |
| 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 |
| 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 |
| 4016216 | If a ZTP script includes a directive to reboot, the reboot might stop the running ZTP process before it is able to disable itself from running again. As a result, the ZTP process starts again when the system comes back up. To work around this issue, run shutdown -r +1 to schedule a reboot after one minute so that the ZTP process can successfully complete disabling the ztp.service systemd service. | 5.10.0 |
| 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. | 5.10.0-5.10.1 |
| 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. | 5.9.1-5.10.1 |
| 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, 5.10.0-5.10.1 |
| 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 |
| 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 |
