Open Issues in 4.4.5
| Issue ID | Description | Affects | Fixed |
|---|---|---|---|
| 4143345 |
On the Trident3 switch, if you use NCLU to configure BGP neighbor shutdown, NCLU stops responding when you include more than 200 neighbors per peer group. If you do not use NCLU to configure BGP neighbor shutdown, you can configure a maximum of 300 neighbors per peer group. | 4.3.0-4.4.5 | |
| 4037015 |
The NVUE commands to delete SNMP users, and change authentication passwords and encryption passphrases are not successful. | 4.3.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
| 3980941 |
After an NMS station does a full SNMP walk on the switch, you see the following message every 5 minutes:snmp : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/cumulus/bin/poectl -j -a This issue occurs because poectl is called on non-PoE switches. To work around this issue, remove or comment out the poetcl call from the /etc/snmpd.conf file, then restart the snmpd process with the sudo systemctl snmpd restart command#snmp ALL = NOPASSWD: /usr/cumulus/bin/poectl -j -a |
4.4.0-5.9.1 | 5.9.2-5.11.0, 5.10.0-5.11.0 |
| 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 | |
| 3684998 |
DHCP lease information is not collected in the cl-support file. |
4.3.0-5.6.0 | 5.7.0-5.11.0 |
| 3528464 |
Cumulus Linux might mark a layer 2 VLAN-tagged packet as a packet to CPU and the INPUT chain ACL might drop the packet. To work around this issue, add an additional addrtype match on the ACL to prevent an erroneous ACL match; for example:[iptables] |
4.3.0-4.4.5 | |
| 3488136 |
When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. |
4.2.1-5.5.1 | 5.6.0-5.11.0 |
| 3474391 |
The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. |
4.3.1-5.5.1 | 5.6.0-5.11.0 |
| 3429530 |
On the Spectrum-2 and Spectrum-3 switch, multiple interfaces (in the same PLL quarter) might flap intermittently at the same time. | 4.2.1-5.4.0 | 5.5.0-5.11.0 |
| 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 | |
| 3400244 |
NCLU accepts multiple instances of same net add bgp commands and stores the configuration in the /etc/frr/frr.conf file when you run the net commit command. As a result, unintended commands might be processed during frr-reload. To work around this issue, edit the /etc/frr/frr.conf file to remove the duplicated entries. |
4.3.1-4.4.5 | |
| 3390022 |
When you restore the switch configuration after upgrading from Cumulus Linux 4.2.x to 4.4.5 and later with ONIE, the configuration lines under the peerlink.4095 interface stanza are duplicated. Subsequent ifreloads, or net commit commands fail until you manually remove the duplicated lines from this interface and run ifreload -a. |
4.2.1-4.4.5 | |
| 3389994 |
During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. |
4.2.1-4.3.1, 4.4.0-5.4.0 | 4.3.2, 5.5.0-5.11.0 |
| 3387852 |
If you remove NGINX from the switch, then run apt autoremove, switchd does not reload because the libyaml-0-2 and python-yaml packages are missing; these packages are required for switchd consistency checking. To work around this issue, reinstall the libyaml-0-2 and python-yaml packages. |
4.4.0-4.4.5 | |
| 3368217 |
When daylight saving time changes, the MLAG initDelay timer resets and all MLAG bonds go down. |
4.4.4-4.4.5 | |
| 3351951 |
Currently, the default core dump size limit on Cumulus Linux is 256M but the SDK generates core dumps around 800M. To avoid incomplete core files, you can increase the core dump size limit. | 4.2.1-4.3.1, 4.4.0-5.3.1 | 4.3.2, 5.4.0-5.11.0 |
| 3339249 |
The sensors.conf files in Cumulus Linux are out of date. |
4.2.1-4.4.5 | |
| 3333064 |
The traffic control rules that the EVPN multihoming configuration adds to an interface are deleted when the hsflowd service restarts. The hsflowd service deletes the EVPN multihoming traffic control filters after you stop hsflowd, then adds back the match-all filters with the psample action; however, hsflowd does not add back the EVPN multihoming traffic control rules. |
4.4.0-5.3.1 | 5.4.0-5.11.0 |
| 3330705 |
When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. |
3.7.0-5.3.1 | 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 | |
| 3321391 |
On the NVIDIA SN2410 switch, ports with optical transceivers show FAULT errors in the sensor command output. |
4.2.1-5.3.1 | 5.4.0-5.11.0 |
| 3303105 |
Clagd crash is observed with the following traceback in /var/log/clagd.log following a clag sync event which is typically driven by a peerlink up event: unhandled exception: Traceback (most recent call last): File “/usr/sbin/clagd”, line 1304, in PeerRecvT PeerRecv() File “/usr/sbin/clagd”, line 513, in PeerRecv ParseProtoBufMessage(nlm, myPeerMsg) File “/usr/sbin/clagd”, line 853, in ParseProtoBufMessage msgData = FdbSync.ParseProtoBufMessage(msgHdr) File “/usr/lib/python3/dist-packages/clag/fdbsync.py”, line 892, in ParseProtoBufMessage msgData.ParseFromString(msgHdr.data) google.protobuf.message.DecodeError: Error parsing message |
4.4.0-4.4.5 | |
| 3293110 |
You cannot set the NTF router flag (NTF_ROUTER) on neighbor entries from the user space. | 4.4.2-4.4.5 | |
| 3292873 |
When you run ZTP manually with the ztp -R command, then the ztp -vb command, the process stalls indefinitely while searching the local (USB) location and not using DHCP information. To work around this issue, run the ztp -r command with the URL of the ZTP server:[Dec-08-17:09:58] root@switch:/home/cumulus# ztp -r http://myztp.server.local/ztp |
4.4.2-4.4.5 | |
| 3291548 |
In EVPN deployments, a buffer lockup for split or pre-split ports can occur on Spectrum-2 and Spectrum-3 switches. As result, traffic coming in on these ports is dropped in the RX buffer. To work around this issue, restart switchd. |
4.2.1-4.4.5 | 5.0.0-5.11.0 |
| 3288156 |
When you configure a new VNI, the VLAN 1 VNI mapping is removed from the VXLAN device. To work around this issue, set the VNI interface mapped to VLAN 1 down and up again. | 4.4.3-5.1.0 | 5.2.0-5.11.0 |
| 3284719 |
Certain EVPN multihoming show commands might cause the bgpd service to crash if you use the json flag and try to reference the default VRF by name. For example: show bgp l2vpn evpn es-vrf json. |
4.4.2-4.4.5 | |
| 3270988 |
After restarting switchd on the NVIDIA SN2100 switch, the FAN speeds are at one hundred percent. To work around this issue, restart the hw-management service. |
4.4.5-5.2.0 | 5.2.1-5.11.0 |
| 3269537 |
When an FRR routing service (such as bgpd) becomes unresponsive, watchfrr might fail to stop and restart service. To work around this issue, restart FRR with the systemctl restart frr command. |
4.4.0-5.3.1 | 5.4.0-5.11.0 |
| 3244740 |
If you have a lot of inbound route maps that match lists with many regex statements, a large number of updates from the peer can cause the system to run out of memory. To work around this issue, reduce the number of regex matches in inbound route maps. | 4.4.0-5.2.1 | 4.3.2, 5.3.0-5.11.0 |
| 3236366 |
When you run docker commands, the command process might crash. The crash can occur during the apt upgrade process, where you can run docker commands implicitly. To work around this issue, run ulimit -v unlimited before running docker commands. |
4.4.5 | |
| 3235368 |
When you try to configure VRF route leaking between many VRFs using multiple NCLU commands before running the net commit command, the commit fails. To work around this issue, configure VRF leaking one command at a time and run net commit after each command. |
4.4.4-5.2.1 | 5.3.0-5.11.0 |
| 3227677 |
When daylight saving time changes the time, the MLAG initDelay timer resets and all MLAG bonds go down. |
4.4.4-5.2.1 | 5.3.0-5.11.0 |
| 3226579 |
The net show interface command output shows Type=Unknown for the specified interface. |
4.4.3-4.4.5 | |
| 3221470 |
Under heavy system load, when many forwarding resources (routes, neighbors, ECMP groups, and so on) are removed from hardware, subsequent attempts to configure additional forwarding resources might fail and you see the following log message:sx_sdk: EMAD_RX_THREAD: EMAD transaction FW error |
4.4.0-5.1.0 | 5.2.0-5.11.0 |
| 3218207 |
Certain routes on tenant VRFs have missing next hop entries because the router MAC address is missing in the bridge forwarding database table that corresponds to the remote VTEP. As a result, traffic forwarding is affected for these routes. | 4.3.0-5.2.1 | 5.3.0-5.11.0 |
| 3216922 |
RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users). |
3.7.0-5.2.1 | 5.3.0-5.11.0 |
| 3216921 |
RADIUS authenticated users with read-only access to NCLU commands (users in the users_with_show list) can run edit commands if a username for a non-local account is on the users_with_edit line of the /etc/netd.conf file. To work around this issue, make sure that all usernames on the users_with_edit line of the /etc/netd.conf file are configured local users for the system (real Linux users) |
3.7.0-3.7.16, 4.3.0-4.4.5 | |
| 3216759 |
With the ip-acl-heavy TCAM profile, the following message might appear after you install an ACL with NCLU or cl-acltool and the ACL might not work correctlyhal_flx_acl_util.c:378 ERR hal_flx_acl_resource_release resource region 0 size 7387 create failed: No More ResourcesTo work around this issue, change the TCAM profile to acl-heavy or ip-acl-heavy with ACL non-atomic mode. |
3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3211369 |

| 3168564 |
In a large scale VXLAN configuration (for example if you have more than 8500 VLANs across ports), switchd might crash when you restart clagd or when all bonds go operationally down, then upOn Trident3 switches running Cumulus Linux 4.3.1, NVIDIA validates the VLAN scale limit for VXLAN deployments with 8500 VLANs across ports with LACP bypass disabled. |
4.3.1-4.4.5 | |
| 3163845 |
If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. |
4.3.1-4.4.5 | |
| 3157240 |
When you try to query REDECN counters with the mlxcmd utility on a bond member port with the following commands, syslog reports an errorsudo /usr/lib/cumulus/mlxcmd roce counters –port |
4.4.4-5.1.0 | 5.2.0-5.11.0 |
| 3150317 |
During a host failure, where a link remains up but LACP stops being sent, the EVPN multihoming ES bond goes into bypass mode active without a link state change. | 4.4.2-5.2.1 | 5.3.0-5.11.0 |
| 3138746 |
The switch duplicates DHCP packets that pass through the VTEP. | 4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3138057 |
When the next hop interface for EVPN type 5 routes flaps, FRR might uninstall the routes and Route install failed appears in /var/log/frr/frr.log. To work around this problem, restart FRR with the sudo systemctl restart frr command. |
4.4.0-5.2.1 | 5.3.0-5.11.0 |
| 3135801 |
Zebra rejects MAC IP updates from BGP when the MAC mobility sequence number that BGP sends is lower than the sequence number known to zebra When the MAC mobility sequence that BGP knows legitimately lowers (due to narrow timing conditions during convergence or after rebooting an MLAG pair one VTEP at a time), zebra rejects these updates and maintains a stale state. If the stale information that zebra uses points to the wrong VTEP address, traffic goes to the wrong VTEP and might drop. |
4.0.0-4.3.0, 4.4.0-4.4.5 | 3.7.16, 4.3.1 |
| 3131423 |
During EVPN multihoming bond failover, ARP and ND redirection fails if you configure layer 2 VNIs and ES bonds before you configure the loopback IP address of the switch. To work around this issue, configure the loopback IP address, then restart FRR with the systemctl restart frr command. |
4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3129819 |
On the EdgeCore AS4610 switch, the clagd service loses communication after 198 days of uptime. |
3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3123556 |
When you configure an interface in FRR to send IPv6 RAs before you configure the interface in the /etc/network/interfaces file, the switch does not process IPv6 RAs. To work around this issue, remove the interface configuration in FRR and reapply it. |
3.7.15-4.3.0, 4.4.0-5.1.0 | 4.3.1, 5.2.0-5.11.0 |
| 3119615 |
In an MLAG topology, if you admin down a single connected interface, any dynamic MAC addresses on the peer link are flushed, then added back momentarily, which creates a disruption in traffic. | 3.7.15-5.1.0 | 5.2.0-5.11.0 |
| 3117340 |
When you edit the /usr/share/openvswitch/scripts/ovs-ctl-vtep file to change the ovs-vtepd configuration between vlan-aware and vlan-unaware mode, ovs-vtepd crashes when you restart the service. To recover, restart the networking service with the sudo systemctl restart networking command. |

After a fresh installation of Cumulus Linux, the package manager reports that the cumulus-archive-keyring package can be upgraded This is a security fix made available after the 4.4.4 image release to change the repository URLs in the /etc/apt/sources.list file from http to https. |
4.4.4-4.4.5 | |
| 3112971 |
When you configure a VRF static route using the legacy command syntax in FRR (for example: ip route 10.0.0.0/8 172.16.1.1 vrf vrf-red), then make subsequent VRF or route configuration changes, FRR might crash. To avoid this problem, use the current method for configuring VRF routes within the VRF stanza:vrf vrf-red |
4.4.3-5.1.0 | 5.2.0-5.11.0 |
| 3112938 |
In the Cumulus-BGPVRF-MIB, the bgpPeerFsmEstablishedTransitions OID always reports a value of 0. |
4.4.4-5.1.0 | 5.2.0-5.11.0 |
| 3093966 |
On Broadcom switches, INPUT chain iptable rules filter IPv6 packets matching the rules. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 3084027 |

| 3072613 |
When you delete a bond interface with NCLU, BGP peer group configuration is removed. | 3.7.15-3.7.16, 4.3.0-4.4.5 | |
| 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 | |
| 3070672 |
TACACS Command Authorization results in a traceback error and command is not executed | 4.4.0-4.4.5 | |
| 3059135 |
In an OSPF configuration, after you change the IPv6 subnet mask, the old address remains in the RIB as a connected OSPF route To resolve this issue, restart FRR with the sudo systemctl restart frr command. |
4.3.0-5.1.0 | 5.2.0-5.11.0 |
| 3046023 |
The cl-resource-query command output shows ECMP nextHop Table exhaustion (above 100 percent utilization) and the switchd.log file contains ECMP resource errors with routes and next hops failing to install. |
4.2.1-5.1.0 | 5.2.0-5.11.0 |
| 3034435 |
In an MLAG EVPN deployment when either of the MLAG peers reboots, FRR incorrectly programs the local host entries in the ARP table as remote. To work around this issue, either restart FRR or use BGP policies to mark and drop routes within an MLAG pair. Both MLAG peers must have an outbound policy that add a community representing the unique MLAG pair to Type-2 EVPN routes and an inbound policy to match and drop that community. | 4.4.4-5.4.0 | 5.5.0-5.11.0 |
| 3032234 |
In BGP unnumbered, when you try to remove an interface from the underlay default VRF with the NVUE nv unset vrf default router bgp neighbor command, the command fails to apply. |
4.4.2-5.0.1 | 5.1.0-5.11.0 |
| 3021838 |
PBR rules that you apply to interfaces in the default VRF install in the kernel with the action lookup local. As a result, packets that match this rule only perform a route lookup in the local table (which contains special routes for local IP addresses and broadcast addresses) but not in the main table (which contains unicast routes). As a result, policy routing might be applied to traffic incorrectly. |
4.4.2-5.0.1 | 5.1.0-5.11.0 |
| 3008388 |
When you set vlan-bridge-binding on for a VLAN interface, the VLAN interface status does not change to down even when all bridge member ports are down. |
4.4.3-5.0.1 | 5.1.0-5.11.0 |
| 3007564 |
After you delete the last vxlan-remoteip configuration line from the /etc/network/interfaces file and run the ifreload -a command, the corresponding BUM flood entry is not removed. |

| 2944167 |
When you use NCLU commands to add a port to a bridge and the port already exists under the bridge, Cumulus Linux removes all other ports from the bridge. | 4.4.2-4.4.5 | |
| 2943443 |
Cumulus Linux lets you add more than one VXLAN interface to same VLAN on the same bridge. This is an invalid configuration as certain Cumulus Linux components, such as switchd, expect a single VNI for a given bridge or VLAN. |
3.7.15, 4.2.1-4.3.0, 4.4.2-5.0.1 | 3.7.16, 4.3.1, 5.1.0-5.11.0 |

The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. |

OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . |

On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel. To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. |

When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
|
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 |
NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. |

| 2540155 |
On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. |
3.7.3-3.7.16, 4.0.0-4.4.5 | |
| 2540042 |
When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails. To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 |
On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 |
Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 |
NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto lines exist. |

When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:
|
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539962 |
When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. |

On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2539124 |
The net add interface command adds no ptm-enable for that interface in the frr.conf file. Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 |
NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG. To restore connectivity, remove the VLAN ID from the bridge. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538590 |
When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 |
On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings. Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 |
If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. |

There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. |

The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 |
For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. |
4.0.0-4.4.5 | |
| 2536242 |
On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 |
On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 |
At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 |
On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 |
The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 |
FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor. To work around this issue, add ttl-security to individual neighbors instead of the peer group. |
4.0.0-4.4.5 | |
| 2535209 |
The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. |

If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict. To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. |
3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 |
PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. |
4.0.0-4.4.5 | |
| 2533337 |
When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. |
4.0.0-4.4.5 | |
| 2531273 |
In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. |

After an NMS station does a full SNMP walk on the switch, you see the following message every 5 minutes:snmp : command not allowed ; TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/cumulus/bin/poectl -j -a This issue occurs because poectl is called on non-PoE switches. To work around this issue, remove or comment out the poetcl call from the /etc/snmpd.conf file, then restart the snmpd process with the sudo systemctl snmpd restart command#snmp ALL = NOPASSWD: /usr/cumulus/bin/poectl -j -a |

When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. |

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 | |
| 3400244 |
NCLU accepts multiple instances of same net add bgp commands and stores the configuration in the /etc/frr/frr.conf file when you run the net commit command. As a result, unintended commands might be processed during frr-reload. To work around this issue, edit the /etc/frr/frr.conf file to remove the duplicated entries. |

When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. |
3.7.0-5.3.1 | 5.4.0-5.11.0 |

If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. |

The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. |
4.2.0-4.4.5 | |
| 2553116 |
When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition.

OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . |

If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. |

When you execute the following command on the Delta AG6248C switch, the switch reboots and then comes right back into Cumulus Linux without installing the new image. The install image is still in /var/lib/cumulus/installer, which causes issues with cl-support.
To work around this issue, use the onie-select command to access ONIE, and then use the nos-install command in ONIE to install a new binary image. |

On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel. To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. |

An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. |

On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings. Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. |

The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. |

For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. |

| 2535986 |
At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. |

If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict. To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. |

PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. |
4.0.0-4.4.5 | |

When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. |

In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2.

Cumulus Linux might mark a layer 2 VLAN-tagged packet as a packet to CPU and the INPUT chain ACL might drop the packet. To work around this issue, add an additional addrtype match on the ACL to prevent an erroneous ACL match; for example:[iptables] |
4.3.0-4.4.5 | |
| 3488136 |
When zebra receives route updates that include both a route with a recursive next hop and the route used to resolve that next hop, zebra might mark the route with the recursive next hop as inactive. To work around this issue, reprocess the route updates by running the appropriate clear command for the protocol in use. For example, for BGP, clear inbound routes from the relevant neighbor using the nv action clear vrf command. |
4.2.1-5.5.1 | 5.6.0-5.11.0 |
| 3474391 |
The SNMP MIB definition file /usr/share/snmp/mibs/Cumulus-BGPVRF-MIB.txt does not define the INDEX of the bgpPeerEntry correctly. This issue does not impact SNMP functionality for this MIB. |

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 | |
| 3400244 |
NCLU accepts multiple instances of same net add bgp commands and stores the configuration in the /etc/frr/frr.conf file when you run the net commit command. As a result, unintended commands might be processed during frr-reload. To work around this issue, edit the /etc/frr/frr.conf file to remove the duplicated entries. |
4.3.1-4.4.5 | |
| 3390022 |
When you restore the switch configuration after upgrading from Cumulus Linux 4.2.x to 4.4.5 and later with ONIE, the configuration lines under the peerlink.4095 interface stanza are duplicated. Subsequent ifreloads, or net commit commands fail until you manually remove the duplicated lines from this interface and run ifreload -a. |
4.2.1-4.4.5 | |
| 3389994 |
During upgrade, when one MLAG node is upgraded and the other MLAG node is not yet upgraded, permanent neighbors cannot synchronize between MLAG nodes. The clagctl dumppermanentneighs command only shows local neighbors. |

When using TACACS+, a TACACS+ server name that returns more than one IP address, such as an IPv6 and IPv4 address, is counted many times against the limit of seven TACACS+ servers, which might cause some of the later listed servers to be ignored as over the limit. To work around this issue, you can set the prefer_ip_version configuration option (the default value is 4) to choose between an IPv4 or IPv6 address if both are present. |
3.7.0-5.3.1 | 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. |

In a large scale VXLAN configuration (for example if you have more than 8500 VLANs across ports), switchd might crash when you restart clagd or when all bonds go operationally down, then upOn Trident3 switches running Cumulus Linux 4.3.1, NVIDIA validates the VLAN scale limit for VXLAN deployments with 8500 VLANs across ports with LACP bypass disabled. |
4.3.1-4.4.5 | |
| 3163845 |
If bond slaves listed in the /etc/network/interfaces file are not in alphabetical order, the bond interface MAC address can change when you run ifreload. For example, if the bond slaves in the /etc/network/interfaces file are listed as swp32 swp31, the switch initially uses the MAC address for swp32 as the bond MAC address. An another ifreload can cause this to change to use the MAC address for swp31 as the bond MAC address, which can cause protocol issues, such as IPv6 link-local address changes. |
4.3.1-4.4.5 | |
| 3150317 |
During a host failure, where a link remains up but LACP stops being sent, the EVPN multihoming ES bond goes into bypass mode active without a link state change. | 4.4.2-5.2.1 | 5.3.0-5.11.0 |

The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. |

The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. |
4.2.0-4.4.5 | |
| 2553116 |
When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition.

OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . |

On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel. To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. |

An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. |

The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. |

On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:

When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:

When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails. To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 |
On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 |
Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:

On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings. Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. |

There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. |

The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 |
For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. |

On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |

On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 |
At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. |

If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict. To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. |
3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 |
PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. |
4.0.0-4.4.5 | |
| 2533337 |
When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. |
4.0.0-4.4.5 | |

In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2.

The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. |

OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . |

If a remote EVPN Sticky MAC [Static MAC address] is unexpectedly learned dynamically on a local interface, the selected entries in zebra and BGP are in an inconsistent state. zebra increments the local MAC mobility sequence number and considers the MAC address to be local, but BGP maintains the remote Sticky MAC as the best path selected. This results in zebra installing the local MAC address and BGP not updating the route for the MAC address. |

On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel. To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. |

When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:
|
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2540340 |
NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf command just displays
Tab completion for the net add vrf command works correctly. |

When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails. To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 |
On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 |
Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540031 |

The net add interface command adds no ptm-enable for that interface in the frr.conf file. Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538790 |
NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan . This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG. To restore connectivity, remove the VLAN ID from the bridge. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |

When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538562 |
On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings. Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 |
If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. |

There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. |

If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. |
4.0.0-4.4.5 | |
| 2536384 |
The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 |
For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. |
4.0.0-4.4.5 | |
| 2536242 |
On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |
| 2536179 |
On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 |
At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535965 |
On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535723 |
The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 |
FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor. To work around this issue, add ttl-security to individual neighbors instead of the peer group. |
4.0.0-4.4.5 | |
| 2535209 |
The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. |

Span rules matching the out-interface as a bond do not mirror packets. | 4.0.0-4.4.5 | |
| 2533691 |
If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict. To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. |
3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 |
PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. |
4.0.0-4.4.5 | |
| 2533337 |
When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. |
4.0.0-4.4.5 | |
| 2531273 |
In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See [Address Resolution Protocol in the Cumulus Linux user guide|https://docs.cumulusnetworks.com/cumulus-linux/Layer-3/Address-Resolution-Protocol-ARP/] for more information. |

FRR does not prevent EVPN routes from being imported into VNIs when they are not needed. For example, you can import a type-5 route into a layer 2 VNI if the configured import route target matches the route target on the type-5 route. When this occurs, the network address of the IP prefix carried within the type-5 route incorrectly shows as a remote VTEP for the layer 2 VNI in the net show evpn vni command output.

FRR does not prevent EVPN routes from being imported into VNIs when they are not needed. For example, you can import a type-5 route into a layer 2 VNI if the configured import route target matches the route target on the type-5 route. When this occurs, the network address of the IP prefix carried within the type-5 route incorrectly shows as a remote VTEP for the layer 2 VNI in the net show evpn vni command output.

The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. |

The default NTP configuration is to use eth0 as the NTP source interface. In Cumulus Linux 4.0 and later, eth0 is in the management VRF by default; therefore the NTP service runs automatically in the management VRF. NVIDIA does not recommend running NTP with a source interface other than eth0 as this can expose a security vulnerability. Changing the NTP source interface name with NCLU to a non-management VRF interface might result in NTP not functioning because the NTP service is still running in the management VRF. |
4.2.0-4.4.5 | |
| 2553116 |
When you manually set the link speed or duplex mode with ethtool to an unsupported value, then run a TDR check against the interface, you encounter a switchd service heartbeat failure.To work around this issue, reboot the switch to clear the condition.

OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . |

On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel. To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. |

Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. |

An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. |

The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. |
3.7.7-3.7.16, 4.0.0-4.4.5 | |
| 2543096 |
When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. |

On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:

When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect:
These commands are correct:

When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails. To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540041 |
On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |
| 2540040 |
Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example:
|
3.7.4-3.7.16, 4.0.0-4.4.5 | |

| 2538562 |
On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings. Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. |
3.7.2-3.7.16, 4.0.0-4.4.5 | |
| 2538294 |
If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. |

There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:
Eventually the dhcrelay service stops. |

The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. |
3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2536256 |
For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.
These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. |

| 2536242 |
On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 4.0.0-4.4.5 | |

On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.16, 4.0.0-4.4.5 | |
| 2535986 |
At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. |

| 2535965 |
On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. |

The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 4.0.0-4.4.5 | |
| 2535605 |
FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor. To work around this issue, add ttl-security to individual neighbors instead of the peer group. |
4.0.0-4.4.5 | |

If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict. To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. |
3.7.12-3.7.16, 4.0.0-4.4.5 | |
| 2533625 |
PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. |
4.0.0-4.4.5 | |
| 2533337 |
When you use NCLU to bring a bond admin down (net add bond ), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown command. |
4.0.0-4.4.5 | |
| 2531273 |
In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2.

The following vulnerabilities have been announced in the openssl packages: CVE-2021-23840: Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. CVE-2021-23841: The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. CVE-2019-1551: There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Vulnerable: <= 1.1.1d-0+deb10u4 Fixed: 1.1.1d-0+deb10u5 |
