| Headline: The grpcnxsdk work thread is not released properly. Symptoms: The observation is that there exists an ongoing gNMI 5-second sample subscription for System/ptp-items/ephoper-items/pastcorrections-items/PtpEphCorrection-list. When this path is queried, the path itself does not let the gNMI SET to take place. 1. The repetitive queries every 5 second of this path triggers a bug, which prevents the query itself from finishing. 2. Then the next gNMI SET is blocked due to this unfinished query. 3. The client script times out and sends more SET requests, which only pile up and use up the max limit of 16 sessions. Workarounds: Kill the grpcnxsdk process to recover automatically and make further queries. |
|
| Headline: Output of the show spanning-tree root command no longer shows "This bridge is root" for non-vPC VLANs.

| Headline: ipfib crashes while using the show system internal forwarding table <> command. Symptoms: The show system internal forwarding table <> command triggers a crash of the ipfib process on a Cisco Nexus 9000 switch running Cisco NX-OS Release 9.3(10) or 10.2(4)M. Workarounds: Avoid using the show system internal forwarding table <> command. |
|
| Headline: Unexpected reload due to tahusd segmentation fault in Timer Code. Symptoms: A Cisco Nexus 9000 switch can reboot unexpectedly due to tahusd process crash, resulting from a segmentation fault, and a reset reason and error log are generated. Workarounds: None |
|
| Headline: Cisco Nexus 9000 VXLAN virtual peer-link tunnel recovery failure. Symptoms: After a specific failure of the virtual peer-link the tunnel used to traverse the CFS traffic can fail to recover after the virtual peer-link is brought back up. The virtual peer-link shows UP. However, VLANS forwarding over the peer-link does not take place and CFS traffic does not make it through the tunnel. Workarounds: Flapping the uplinks that are used to build the virtual peer-link forces the virtual peer-link to re-initialize and recover from this state. If flapping the uplinks does not recover the peer-link, a reload is required. |
|
| Headline: Cisco N93108TC-FX3P triggers high clock offset spike during GM failover in PHY PTP mode. Workarounds: None. However, the corrections settle down after some time (max 5 mins). |
|
| Headline: LPM entry gets stuck after multiple BGP withdraws. Symptoms: In an ECMP environment where the BGP prefixes have constant withdraws, it is possible for the single entries (no ECMP) to get stuck in the LPM table. Consequently, the ECMP entry ends up installed at the end and deferred, because the first or the older entry is honored. Workarounds: Choose any one of the following workarounds:
●
Clearing the route works as a temporary workaround, as this forces NX-OS to put the ECMP entry at the top. However, another withdraw can occur leading to the same condition.
clear ip route x.x.x.x/x
●
Clearing the LPM entry works as a better workaround. However, if the constant withdraws continue the same condition can recur.

|
| Headline: Cisco Nexus C93360YC-FX2 FC interface randomly reset or error disabled by peer switch. Symptoms: FC link throughput is degraded, or the link is error disabled by the peer switch. This issue can be confirmed on the peer switch when it logs the E_LINK_RXBUF_NOT_AVAIL events for the affected FC interface. These events trigger the peer to send Link Reset to reset the credits on the interface. Workarounds: None |
|
| Headline: Archive configuration is missing after upgrade from Cisco NX-OS Release 9.3(10) to 10.2(4)M. Symptoms: After upgrading from Cisco NX-OS Release 9.3(10) to 10.2(4)M, the archive configuration is lost.

Workarounds: Migrate to Cisco NX-OS Release 10.2(5)M instead of 10.2(1)F, 10.2(2)F, 10.2(3)F, or 10.2(4)M. |
|
| Headline: Cisco Nexus 92348GC consumes -XF license instead of -GF license. Symptoms: Cisco Nexus 92348GC platform should consume GF licenses; instead, it is consuming XF licenses, when respective features are enabled. Workarounds: None |
|
| Headline: Unicast route create fails and Cisco Nexus 9000 tahusd crashes. Symptoms: Cisco Nexus 9000 switch running with LPM-heavy mode has Unicast route create failure resulting in failed logs. After a second, service tahusd also crashes. Workarounds: None |
|
| Headline: Certain interfaces show input/output rate as 0pps on Cisco Nexus 9300-GX platform switch. Symptoms: Certain interfaces show input/output rate as 0pps on Cisco Nexus 9300-GX platform switch without any operations. Workarounds: Perform the following workaround to clear the issue: 1. Flap one of the ports. 2. Reactivate the DMA state with internal commands. 3. Connect a new terminal to the port to which the DMA Group belongs to reactivate the DMA Group. |
|
| Headline: The xbar multicast show command causes 300 MB of memory to be allocated. Symptoms: Executing the show system internal xbar multicast_id all command, results in no output. However, 300 MB of memory is allocated to XBM_MEM_xbm_mcast_group_info_t. Workarounds: Clear the memory allocation by reloading the switch. Then avoid running the show system internal xbar multicast_id all command, and also commands such as show tech-support details. |
|
| Headline: The show spanning-tree internal info global command output is truncated at SWOVER Timeout. Symptoms: The show spanning-tree internal info global command does not show the full output. The output stops at the following line: SWOVER Timeout (sec). Once this issue comes up, the issue repeats. Workarounds: None |
|
| Headline: Cisco Nexus 9300 NBM-related syslog does not comply with standard NX-OS syslog format. Symptoms: NBM error messages get logged too frequently. Workarounds: None |
|
| Headline: Cisco Nexus 9000: urib core seen leaving only local routes on switch Symptoms: Cisco Nexus 9000 running the impacted code keeps running but leads to urib process crash. The switch remains up but as this process operated the Unicast RIB table, routing information is lost for a short moment. The tables are repopulated, and normal operation should resume. Workarounds: Restart the BGP process to get out of the problem state. Instead of using the non-cached ip route commands, use any one of the following commands (as applicable) through Netconf:
●
show ip route summary cached vrf all
●
show ipv6 route summary cached vrf all
|
|
| Headline: Error or incorrect result when computing multiple file hashes simultaneously. Symptoms: The Cisco Nexus 9000 switch can throw an error when multiple file hashes are being computed at the same time by multiple SSH sessions: ck.out Empty / cksum or md5sum or sha256sum or sha512 calculation Error. Alternatively, the wrong hash can be reported for some of the computed files. Workarounds: Wait for File A to hash before starting the hash for File B. |
|
| Headline: Show commands collected through NX-API have missing character with 8k fastcgi buffers. Symptoms: Cisco Nexus 93240YC-FX2 running on Cisco NX-OS Release 10.2(2a) uses 8k fastgci buffers by default. When large outputs are requested from REST, errors are consistently seen where the 8076th character is missing. Workarounds: None |
|
| Headline: Cisco Nexus 9000 Switch reloads due to tahusd memory leak. Symptoms: Cisco Nexus 9000 switch reloads due to a memory leak in the tahusd process. Workarounds: No workaround to prevent the memory leak. However, reload the switch to clear the memory leak. |
|
| Headline: Stuck MDIO access with BV ports leads to missed HBs and USD kill. Symptoms: Tahusd process crashes resulting in box reload. Workarounds: None |
