Workarounds: None.

CSCwe00551

Headline: Multicast first packet failed to create (S,G) entry on LHR.

Symptoms: The following symptoms are seen:

Workarounds: None.

CSCwe01333

Headline: Object number in the Track list turns to 0 after upgrade from Cisco NX-OS Release 9.2(3) to 10.2(4).

Symptoms: Upgrade the N9K-C93180YC-FX device from Cisco NX-OS Release 9.2(3) to 10.2(4) (disruptive upgrade). Post upgrade, the object value changes from original to 0 not.

Workarounds: Re-deploy the missing part of the configuration.

CSCwe01850

Headline: After customer upgrades the Cisco Nexus 9000 switch from Cisco NX-OS Release 9.3(9) to 10.2(4), ARP does not learn, and STP-state remains inconsistent.

Symptoms: After Cisco Nexus 9000 switches are upgraded from 9.3(9) to 10.2(4), ARP goes into an Incomplete state and STP state is inconsistent for most VLANs.

Workarounds: Re-configure the port-channel.

CSCwe07768

Headline: Cisco Nexus 9300-GX platform puts BFD in default Queue.

Symptoms: When output discards are seen on a GX platform that are all a part of Queue 0, BFD flaps intermittently and goes down after the TAHUSD Buffer threshold messages kick off.

Workarounds: Manually configure a QoS policy to set BFD packets to QoS group 7 (priority queue).

CSCwe08697

Headline: 40G Links flap during ISSU from 9.3(10) to 9.3(11) on N9K-X9464PX.

Symptoms: Failure of In-Service Software Upgrade (ISSU) when upgrading from Cisco NX-OS Release 9.3(10) to Cisco NX-OS Release 9.3(11) with FEX connection on N9K-X9564PX LC 40G interface.

Workarounds: None.

CSCvw58434

Headline: NAT core is seen when running NAT sanity.

Symptoms: NAT process crash and system reload is observed when user configures or unconfigures the NAT inside or outside on Layer 3 interface.

Workarounds: None.

CSCvw30328

Headline: The copy r s command gets aborted.

Symptoms: If VRF is not up, the interface configuration entered on SVI interfaces belonging to a VRF may not be applied. When attempting to save the configuration, the log shows configuration copy aborted or configuration copy failed.

Workarounds: Bring up the VRF before adding configuration.

CSCvx84922

Headline: Interim ACL rule programmed during non-atomic update does not function as expected.

Symptoms: During the brief time interval required for the device to update an ACL, an issue with non-atomic updates of Access Control Lists (ACLs) on Cisco Nexus 9000 Series switches may result in traffic being permitted instead of being denied.

Workarounds: None. This issue only affects the brief time interval required for the non-atomic update of the ACL and the expected ACL behavior is enforced after that.

CSCvy75335

Headline: The vmtracker process crash and box potentially reloads with vmtracker configs.

Symptoms: When the vmtracker configurations are added on a Cisco Nexus 9000 switch, the vmtracker process may crash and potentially reload the entire switch.

Workarounds: Remove the vmtracker configurations if they are not in use. Otherwise, upgrade to a release with the code fix.

CSCvz43168

Headline: N9K-C9336-FX2 - 10.1(2) and 9.3(8) - Fan speeds drop to as low as 20%.

Symptoms: When N9K-C9336-FX2 runs on 9.3(8) or 10.1(2) code, temperature alarms occur and the difference in speed is observed in the output of the show environment fan detail command.

Workarounds: Perform any one of the following workarounds:

CSCvz67451

Headline: Bootflash lifetime usage threshold syslog shows incorrect usage value in the show command.

Symptoms: The following syslog appears when the switch reaches a lifetime usage value of 95% on the bootflash.
PLATFORM-2-BOOTFLASH_LIFETIME_MAJOR: Bootflash lifetime usage crossed 95%.
Collect the output of the show hardware internal bootflash log command and consult the product support team. When the recommended command is checked the output has inaccurate usage percentages. These percentages make it difficult to determine whether the syslog is correct and whether the switch has an issue.

Workarounds: None.

CSCvz89475

Headline: Cisco Nexus 9300-FX2/FX3 sends untranslated packets using twice NAT when one HW entry is already installed.

Symptoms: With twice NAT configuration with pool and overload, packets with untranslated destination address (pool address as destination) are seen in the out-to-in direction.

Workarounds: Configure ip nat translation creation-delay 0 in this situation and minimize the time window for which untranslated packets are received. However, the problem may persist.

CSCvz01927

Headline: ARP process crash.

Symptoms: ARP process crash is seen when the show ip arp vrf XXX commands are executed frequently.

Workarounds: To reduce the crash risk, do not run the show ip arp vrf XXX commands too often while ARP entries add/deletes are in progress in the scaled environment.

CSCwa05191

Headline: Interface track configured under sub-interface does not work after reload.

Symptoms: Interface track is configured under sub-interface. When switch comes back from reload, interface track does not work. For example, an interface track is configured under sub-interface where HSRP is also configured, and the tracked interface is up. However, HSRP still recognizes that the tracked interface is down.

Workarounds: Do not use sub-interface. With parent interface (no sub-interface) or SVI, this configuration should work correctly.

CSCwa77878

Headline: Default MTU is seen in running-config when non-default value is configured under network-qos class-map.

Symptoms: When configuring non-default values (dpp, pause, and so on) under class-map in network-qos policy-map, default MTU, for example, mtu 1500, is shown in show running-config and cannot be deleted by the no mtu 1500 command. Default value should not be shown in show running-config.

Workarounds: None. Note that though the default value is seen in running-config, there is no impact on the switch functionality.

CSCwa90917

Headline: Cisco Nexus 9000 PKI Authentication Failure.

Symptoms: Unable to log in to Cisco Nexus 9000 using certificate-based login.

Workarounds: None

CSCwa92834

Headline: Enhancement to tweak the PLL value through non hidden command.

Symptoms: Link flaps between Cisco Nexus 93180 and Cat 9200 switch due to jitter tolerance in the signal.

Workarounds: Contact TAC for assistance.

CSCwb11701

Headline: Cisco Nexus 9000 - One or more VRFs are stuck in Delete Holddown due to BGP RNH route cleanup issue.

Symptoms: One or more VRFs are stuck in Delete Holddown because RNHs are not deleted. Also, one or more routes in BGP event-history are stuck trying to resolve RNH approximately every 100 ms. This issue is seen when VRF is configured under BGP but does not have associated VRF context defined.

Workarounds: Delete all stale or missing VRFs under BGP using the no vrf NAME command where NAME should be replaced by every missing VRF.

CSCwb12531

Headline: Cisco Nexus 9000 - Memory leak in LLDP (FU_MEM_fu_gwrap_t ) after removing or reapplying VRF context.

Symptoms: LLDP Memory is incrementing when VRF is removed or recovered.

Workarounds: None.

CSCwb28215

Headline: Cisco Nexus 9000 - Continuous MTM flow control condition hit syslogs seen on Cloudscale platforms.

Symptoms: The following syslog prints frequently though no significant MAC moves occur on the device:

 2022 Jul 20 03:41:25.275 Nexus-SWITCH %TAHUSD-SLOT1-4-
 TAHUSD_L2_LEARN_DISABLE_MTM_FLOW_CTRL: Unit-1: MTM flow control condition
 hit [pending_msgs:10]

Workarounds: This issue is cosmetic as the logs are printing for existing MAC entries, not just new learns or updates. However, change MTM logging level as follows:

 Nexus9000# configure terminal
 Enter configuration commands, one per line. End with CNTL/Z.
 Nexus9000(config)# attach module 1
 module-1# configure terminal
 Enter configuration commands, one per line. End with CNTL/Z.      
 module-1(config)# logging level mtm 3

CSCwb66035

Headline: For fabric interface, is-dci is set to TRUE.

Symptoms: The issue can occur if the remote BGW’s multisite IP address is seen over the fabric link by consulting the RIB when fabric link is initializing (bringing itself up). BUM traffic is dropped and this can impact ARP, multicast, and broadcast packets. Hosts on Site A cannot perform ARP resolution to Site B.

Workarounds: Make sure the multisite IP addresses of remote BGWs are not reachable through the fabric link when the fabric link is bringing itself up. The is-DCI consults the routing table for the peer IP of the remote multisite BGWs to verify whether the link is DCI link or not.

CSCwb83283

Headline: Memory leak due to port profile.

Symptoms: Memory leaks are observed post SNMP CLI operations.

Workarounds: Use REST GET or SNMPWALK/GET (avoid show commands).

CSCwb92400

Headline: Changes in the way the show hardware internal buffer info pkt-stats is collected in show techs.

Symptoms: The existing show tech-support command outputs collect buffer stats only for module 1 and instance 0. These outputs do not present all information if the show tech command output is collected on switch with LC module which has more than one instance. For example, 9364GX switch has 4 instances ------ > show tech output will collect stats only for one of those instances. There is no output present for instance 1, 2, and 3. However, output is collected only for instance "0".

Workarounds: None.

CSCwb93820

Headline: Cisco Nexus 9000/TRM - Invalid host entry in hardware after mcast source is moved between sites.

Symptoms: Traffic destined to IP address of multicast sources can be forwarded by CPU or drop after multicast sources are moved between EVPN sites. This issue is seen on transit sites that do not have directly connected sources or receivers. This is due to invalid HW entry in host route table that has destination IP redirect to CPU set. This can be verified by CLI.

Workarounds: Move host again between sites or stop multicast traffic and wait until S,G entry expires.

CSCwb99044

Headline: Need to remove mandate of L2VNI with dci-advertise-pip.

Symptoms: NVE peering goes down across multisite.

Workarounds: Create dummy L2VNI for NVE peering to work.

CSCwc08583

Headline: The vPC peer is alive for counter does not increase.

Symptoms: vPC peer is alive for counter does not increase when IPv6 is configured for keep-alive. This counter moves for msec but shows 0 for seconds.

Workarounds: Use IPv4 instead.

CSCwc21224

Headline: ACLQoS crash due to hap reset @ tlv_aligned_array_get_next_tlv.

Symptoms: Switch crashes due to an ACLQoS process crash, as seen in the outputs of the show version or show module internal exceptionlog command.

Workarounds: None.

CSCwc24060

Headline: Cisco Nexus 9000 - Inner tag removed when traffic crosses vPC peer-link.

Symptoms: Dot1q tunneled traffic has its inner tag removed or stripped when crossing the peer-link of the vPC pair.

Workarounds: Disable and enable the system dot1q-tunnel transit vlan <vlan-id> (for the provider VLANs) command to solve the forwarding issue.

CSCwc25401

Headline: Set DHParam for Cisco NX-OS Release 9.3(9) to 2048.

Symptoms: Enhancement to adjust the current Cisco NX-OS Release 9.3(x) code with a SMU to set the DHParam from the default of 1024 to a new value of 2048 to fix scanning issue.

Workarounds: Upgrade to Cisco NX-OS Release 10.2(3) or 10.3(1) to remove the ciphers in question: DHE-RSA-AES128-GCM-SHA256, DHE-RSA-AES128-SHA256, and DHE-RSA-AES256-GCM-SHA384.

CSCwc26955

Headline: LACP egress is set to incorrect traffic class.

Symptoms: LACP Tx direction may drop LACP PDU randomly due to incorrect TC values set. Such control plane flow is always expected as TC0. However, in the current release, it is TC7.

Workarounds: Shut down or remove the monitor session.

CSCwc30146

Headline: IPv6 packet does not include Layer 3 header when calculating MTU.

Symptoms: IPv6 packet does not include Layer 3 header when calculating MTU, which causes few packets that crossed MTU to get transferred with default MTU setting (1500) on Cisco Nexus 9000.

Workarounds: None.

CSCwc34293

Headline: N9K-C9336C-FX2 Multicast Tx SPAN does not work.

Symptoms: N9K-C9336C-FX2 Multicast Tx SPAN does not work. Configure multicast Tx span source, but no output is seen on span dst.

Workarounds: None.

CSCwc35610

Headline: PSU actual input and output power are 0 after upgrade to Cisco NX-OS Release 9.3(9).

Symptoms: The output of the show environment power command shows the actual power input and output as 0, though the box is working fine, and no Power failure alert is seen in the log.

Workarounds: None.

CSCwc36651

Headline: EEM - event fib route does not work.

Symptoms: Unable to generate or trigger syslog with the EEM event fib route feature.

Workarounds: None.

CSCwc36942

Headline: UC_RPF_FAIILUR/uRPF is kept on even when recreating SVI with no uRPF.

Symptoms: Asymmetric traffic are dropped with the ELAM final drop of UC_RPF_FAIILUR.

Workarounds: Perform any one of the following workarounds:

CSCwc37654

Headline: Cisco Nexus 9300 NAT breaks short-lived passive data FTP sessions with non-zero NAT creation-delay.

Symptoms: Short-lived passive FTP data session fails. Data session does not work.

Workarounds: None.

CSCwc38530

Headline: BGP with MD5 authentication does not form between switches that use non-default vrf with long name.

Symptoms: When trying to form BGP with MD5 authentication between 2 directly connected switches in VRF with 32-character name, BGP does not come up.

Workarounds: Perform the following workaround:
1. Shorten VRF name from at least one side (even by 1 character).
2. Remove MD5 authentication.

CSCwc40726

Headline: Cisco Nexus ACLQoS event-history error output is missing in ACLQoS TS and TS detail.

Symptoms: Module level ACLQoS tech-support output is missing in the tech-support detail.

Workarounds: Collect missing output separately. Module level aclqos tech-support can be collected through slot <slot no> quoted in the show tech-support aclqos command output.

CSCwc41076

Headline: Cisco Nexus 9000 - Packet loss during initializing FEX HIF after FEX comes online.

Symptoms: In AA FEX topology, when shut/no shut of the NIF (vPC leg) is done on the Primary SW (HSRP) and the FEX comes online again, ARP reply to the host connected to the FEX from the SW is dropped on the SW until HIF on the FEX comes up on the SW.

Workarounds: None.

CSCwc42251

Headline: LLDP crashes when configuring it on the device.

Symptoms: When trying to configure LLDP, it crashes. Though the LLDP feature is enabled, it does not run. Disabling and re-enabling the feature lldp in the configuration does not help either.

Workarounds: None.

CSCwc43397

Headline: Memory leak in the NGINX process.

Symptoms: Nexus switch memory usage might be constantly increasing due to the NGINX process.

Workarounds: None.

CSCwc44309

Headline: Cisco Nexus 9300 single NAT without AU breaks passive data FTP session flow after a successful initial start.

Symptoms: Passive FTP session data transfer fails to complete.

Workarounds: None.

CSCwc48255

Headline: VSH process crash.

Symptoms: This is a VSH shell crash that does not have an impact on the system and production environment. When this VSH shell crash happens, a user issuing a CLI is disconnected from the device and a core file is generated. [show cores]

Workarounds: None. The VSH crash has no impact on the switch. The switch recovers on its own.

CSCwc48758

Headline: CoPP fails to apply, and no syslog is generated when PPF session fails.

Symptoms: Under some rare circumstances, CoPP may fail to apply on system boot (PPF timeout).

Workarounds: Use the show copp status command to validate that the CoPP is applied.

CSCwc52440

Headline: LACP port-priority configuration does not take effect on platforms which do not support DME.

Symptoms: LACP port-priority will not take any affect:

 switch(config-if)# lacp port-priority 500
 switch(config-if)# show lacp interface ethernet 1/1

Workarounds: None

CSCwc52574

Headline: Cisco Nexus 9000 - SRC VTEP Peer IP 0.0.0.0 seen in the show nve peers command output.

Symptoms: SRC VTEP peer IP 0.0.0.0 is listed in the output of the show nve peers command.

Workarounds: Flap NVE Interface to clear and recreate peer entries. Then, reload the affected switch.

CSCwc53865

Headline: Cisco Nexus 9000 - show npv flogi-table command output is split across two lines.

Symptoms: The output of the show npv flogi-table command splits the output in two lines. The command output for these types of platform-independent commands must be consistent as it was in the original output format and not split into two lines.

Workarounds: None.

CSCwc55730

Headline: PIM-Process Crash

Symptoms: %SYSMGR-3-HEARTBEAT_FAILURE: Service "pim" sent SIGABRT for not setting heartbeat for last 7 periods. Last heartbeat 210.94 secs ago.

Workarounds: None; PIM restarts after the crash.

CSCwc56079

Headline: High PTP correction on -R line cards is seen during 2 PTP GMs failover.

Symptoms: On the Cisco Nexus 9000 fabric, high PTP correction is seen on the -R series-based line cards on Cisco Nexus 9500 (more than ~600 ns) during PTP GM failover with different GM ID.

Workarounds: None.

CSCwc59099

Headline: Cisco Nexus 9000 Syslog - %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 98%.

Symptoms: Cisco Nexus 9000 switch running NX-OS Release 9.3(9) may print logs indicating one of the line cards has high memory usage in a tmp directory. The syslog states that the temporary directory is full (usage is unexpectedly high at 98%) as seen in the output of the show logging log command.

Workarounds: PSS debugs for mts-mgr process is turned on by default in Cisco NX-OS Release 9.3(9). Hence, the file is filled whenever there is any PSS activity on the mts-mgr process such as show running-config, update config, and copy running-startup. If the system is being subjected to such activity, then the file gets updated. Follow the below procedure, whenever the system is rebooted, to prevent this file from getting filled:

1. Get the uuid of the mts_mgr process from the CLI.
2. Convert the UUID in the above command in HEX to decimal format.
3. Turn off PSS debugs by running the command on CLI.
4. Clear all the logs in the files.
5. Monitor the system for changes to the file.

CSCwc59914

Headline: Unable to apply PACL when TCAM template is enabled.

Symptoms: On a Cisco Nexus 93180YC-EX that has a TCAM template configured, the “ERROR: TCAM region is not configured. Please configure TCAM region and retry the command.” error is seen when a PACL is applied to an interface. However, the TCAM hardware/software outputs indicate that the ing-ifacl (PACL) region is configured and has space available.

Workarounds: Remove the TCAM template configuration and configure TCAM region using the hardware access-list tcam region ing-ifacl 256 command.

CSCwc60753

Headline: VRRP stuck in INIT.

Symptoms: VRRP may be stuck in INIT state indefinitely after reloading.

Workarounds: Shut/no shut the affected interface.

CSCwc65941

Headline: Increasing input overruns on the management interface on Cisco Nexus 9000.

Symptoms: Observed increasing in input overruns on the management interface (mgmt0) on Cisco Nexus 9000, when receiving LLDP packets from the Cisco Catalyst (WS-C2960X-48T) switch.

Workarounds: Disable the LLDP configurations on the Catalyst switch for the mgmt0 attached port.

CSCwc66335

Headline: Cisco Nexus 9000 - SRCTEP Peer Entry Missing in HW.

Symptoms: BUM traffic received on VTEP is dropped with the INFRA_ENCAP_SRC_TEP_MISS reason. This is due to the Source VTEP entry for peer missing in the hardware. The peer entry will be present in NVE and IPFIB though.

Workarounds: None.

CSCwc67943

Headline: Cisco Nexus 9000 TRM - SA-AD not triggered from the Turn-around router.

Symptoms: Cisco Nexus 9000 TRM - SA-AD is not triggered from the Turn-around router.

Workarounds: None.

CSCwc70139

Headline: L2ACLredirect failures do not result in kernel panic.

Symptoms: L2ACLredirect failures do not result in kernel panic especially for -R chassis and line cards.

Workarounds: Apply the following EEM for force reload:

 event manager applet gold_l2acl override __L2ACLRedirect
   action 1 syslog priority emergencies msg L2ACL_test_failed_reloading
   action 2 reload force

CSCwc70147

Headline: Reload force does not work with T+ EEM.

Symptoms: Default EEM action reload does not work. The force keyword gets added twice in the running config and cannot be removed.

Workarounds: None.

CSCwc71075

Headline: When authentication is used, OSPFv3 neighborship is brought down while issuing no feature nv overlay.

Symptoms: Enable feature nv overlay on the Nexus switch and then disable it using no feature nv overlay. All existing OSPFv3 neighborships go to DOWN state.

Workarounds: Remove OSPFv3 authentication under interface.

CSCwc73361

Headline: MPLS Labels are not advertised to neighbor switches after reboot on Cisco Nexus 9336C.

Symptoms: Network topology is configured with Segment Routing. MPLS network for L3VPNS on 4 X Cisco Nexus 9336C switches (NX-OS mode). OSPF is used as IGP and advertises the MPLS labels. Labels are learnt after they are configured. After any one of the Cisco Nexus devices is rebooted, the labels from the switch are no longer advertised by the switch that was rebooted to any other neighboring Cisco Nexus devices. The same behavior repeats for any switch that is rebooted. OSPF database opaque external type 7 prefix is not generated or advertised by the rebooted switch to other neighbor switches.

Workarounds: When a command is entered under the segment routing configuration section, for example, global block range or a prefix, something triggers the labels to be advertised through OSPF. The type 7 prefix is visible in the OSPF database and subsequently installed in the MPLS forwarding table of the remaining three switches. Remove p2p config from the loopback interface.

CSCwc78473

Headline: Cisco Nexus 9500 delays sending BPDUs every 60 seconds.

Symptoms: A Cisco Nexus 9500 switch might delay sending out spanning-tree BPDUs every 60 seconds.

Workarounds: None.

CSCwc79911

Headline: vPC is in down state with reason shown as Inactive after adding VLAN VNI and peer-ip from another VXLAN.

Symptoms: VLAN is removed from the active VLANs list on vPC peer-link port-channel after VLAN vn-segment configuration changes.

Workarounds: Delete or re-configure the missing VLAN on both vPC peers using the no vlan <vlan_id>vlan <vlan_id>vn-segment <segment-id> command.

CSCwc80086

Headline: Cisco Nexus 9000 sysmgr crashes due to incorrect core pattern in the Cisco NX-OS Release 7.0(3)I7(x) result in LC/FM reload.

Symptoms: Following are the symptoms:
1. Cisco Nexus 9000 EOR with BCM linecard or N9K-C9508-FM crashes due to sysmgr.

show cores
VDC  Module  Instance  Process-name     PID       Date(Year-Month-Day Time)
---  ------  --------  ---------------  --------  -------------------------
1     2           1               sysmgr                 XXXX        2022-08-09 16:58:27
1     24         1               sysmgr                 XXXX        2022-08-19 06:30:11
1     24         1               sysmgr                 XXXX        2022-08-20 04:58:48

2. System uptime is nearly two years.
3. OBFL can fail after the crash and RMA may be needed.
4. These logs can be seen in previous reboots of the line card.

Workarounds: None. NX-OS upgrade is required to avoid another line card or module reboot for the same reason.

CSCwc81130

Headline: Log reports that the N9K-C92348GC's PSU went down and up in 1-3 sec.

Symptoms: Syslog reports that the N9K-C92348GC's PSU went down and up in 1-3 sec.

Workarounds: None. This is a cosmetic error and PSU keeps providing power to the switch.

CSCwc81429

Headline: PHY ports stay linked up when peer is powered off.

Symptoms: On N9K-X9788TC2-FX and N9K-C93108TC2-FX platforms, when the peer reloads, the link does not go on few occasions.

Workarounds: None.

CSCwc84291

Headline: KIM Process MTS Buffers are stuck.

Symptoms: KIM Process has messages stuck in the MTS queue. Kernel error messages may be seen in the syslog for net device.

Workarounds: Reload the switch.

CSCwc87548

Headline: Underrun errors transmitted when upgrading from 40 to 100 Gbps on a EOR Cisco Nexus 9000.

Symptoms: When the SFP is replaced to support 100G (QSFP-100G-SR4) or by changing the speed of the port (QSFP-40/100-SRBD), transmitting of underrun packets begins. However, though the output errors counter does not increase locally, the CRC starts increasing on the neighbor device. These ports are configured on a layer 2 Port channel (no vPC). While working at 40G no CRC are seen.

Workarounds: Downgrade to 40 Gbps.

CSCwc87567

Headline: Cisco Nexus 9000 - VXLAN Multisite vPC with dci-advertise-pip tenant VRF CPU generated traffic still uses VIP.

Symptoms: On Cisco Nexus 9000, when VXLAN Multisite vPC is configured with dci-advertise-pip, the CPU generated traffic within the tenant VRF still uses the shared NVE source loopback VIP. Packets are punted to CPU and seen in ethanalyzer on remote Bordergateway. ELAM reports UC_TENANT_MYTEP_BRIDGE_MISS and ROUTING_DISABLED. This is because the VIP is not listed as an NVE peer on the remote Bordergateway, only the PIPs are advertised with dci-advertise-pip.

Workarounds: None, if both vPC and dci-advertise-pip are required to be configured.

CSCwc88680

Headline: Optimize Libutil_is_dme_enabled to accommodate timing of critical paths.

Symptoms: There could be STP topology change in few conditions.

Workarounds: None.

CSCwc88702

Headline: Cisco Nexus 9000 syslog shows - Failed to open file: No such file or directory - securityd -post upgrade to Cisco NX-OS Release 9.3(9).

Symptoms: Cisco Nexus 9000 generates the following syslog message periodically after upgrade to Cisco NX-OS Release 9.3(9): %USER-3-SYSTEM_MSG: Failed to open file: No such file or directory – security. Log appears after upgrade. However, no other changes seen.

Workarounds: None; log is cosmetic.

CSCwc90986

Headline: Unable to configure the ip tacacs source-interface command when feature password encryption aes is configured.

Symptoms: When feature password encryption aes is configured on the device, the ip tacacs source-interface command cannot be configured. The command is accepted but not reflected in the configuration.

Workarounds: Remove feature password encryption aes. Remove feature tacacs. Configure feature tacacs+ and ip tacacs source-interface.

CSCwc93774

Headline: Cisco Nexus 9000 - NetFlow configured under VLAN configuration range takes longer than expected.

Symptoms: When configuring NetFlow under VLAN configuration for large range (for example, 1-999), the command takes 15 minutes to complete.

Workarounds: None.

CSCwc97662

Headline: 40G RWX programming is incorrect, can lead to MAC under-run.

Symptoms: Output errors seen in TX interface where the traffic profile is 100g -> 40g. Additionally, TAHUSD_MAC_INTR_TX_UNDERRUN_MAC is seen in the output of the show hardware internal tah event-history front-port X lane 1 command.

Workarounds: None.

CSCwc98298

Headline: Cisco Nexus 9300 NAT does not translate TCP flow packets randomly.

Symptoms: Packets of random TCP flow may be sent untranslated in the in-out direction.

Workarounds: None.

CSCwc98903

Headline: Mac-address is not synchronized between vPC nodes.

Symptoms: Mac address does not synchronize between the vPC peers when the NVE interface and/or the uplinks flap.

Workarounds: Remove feature NVE overlay from the running config.

CSCwc99674

Headline: DME inconsistency when custom COPP policy

Symptoms: The show consistency-checker dme running-config enhanced command fails.

Workarounds: None.

CSCwc98328

Headline: %PORT-5-IF_DOWN_LINK_FAILURE - Link failure Link reset failure.

Symptoms: The following syslog messages are seen in Cisco Nexus C93360YC-FX2 running Cisco NX-OS Release 10.2(3):

2022 Sep 12 11:34:30 N9KSW1 %PORT-5-IF_TRUNK_DOWN: %$VSAN 2%$ Interface fc1/96, vsan 2 is down (Gracefully shutdown)  
2022 Sep 12 11:34:30 N9KSW1 %PORT-5-IF_DOWN_LINK_FAILURE: %$VSAN 2%$ Interface fc1/96 is down (Link failure Link reset)

Workarounds: None.

CSCwd03152

Headline: VLAN Mapping issue and STP inconsistency with single leg vPC.

Symptoms: A Cisco Nexus 9000 switch runs on Cisco NX-OS Release 9.3(9), and vPC connects to downstream access switch with single link. The switch runs VXLAN and vPC port channels that have PV mapping configuration. STP state of the configured vPC port channel will be in forwarding state, even though the port is in shut state. The translated VLAN is in downstream access. The VLAN will be in a broken state due to wrong BPDUs being received.

Workarounds: Enable both links from vPC primary and secondary towards the access switch.

CSCwd06720

Headline: Removing one object-group causes statistics for the whole ACL to be disabled.

Symptoms: Removing one port object-group causes the statistics for the whole ACL to be disabled. Both IPv4 address object-group and port object-group are configured under the same rule. If one of the port object-groups is not configured or removed from config, statistics for the other entry will be disabled.

Workarounds: Remove entry from ACL for which the port object-group has been removed or not configured.

CSCwd11687

Headline: Cisco Nexus 9000/XXX -R ARP reply packets are dropped in Cisco Nexus 9000 received if it is received from peer-link.

Symptoms: ARP resolution issue is seen on devices connected to Cisco Nexus 9000 devices with -R linecards. Unicast ARP reply packets are not forwarded from Cisco Nexus 9000 device SVI to the host across the peer-link and instead redirected to CPU of vPC peer and dropped.

Workarounds: Shut and no shut VPC peer-link.

CSCwd13471

Headline: SNMP trap does not send to specific server.

Symptoms: With below SNMP config, after reloading, SNMP trap is only sent to X.X.X.2 and X.X.X.3, not sent to X.X.X.1.

Workarounds: Remove existing configuration and reconfigure hosts after reloading of device or SNMP process restart.

CSCwd15262

Headline: Netconf crash during an RPC call.

Symptoms: The service Netconf in a Cisco Nexus device can fail after performing an RPC. This crash can leave the Netconf process unstable.

Workarounds: None.

CSCwd21451

Headline: SNMP walk on any OID not return with expected results.

Symptoms: SNMP walk on any OID not return with expected results, for example, ipAdEntAddr. IP-MIB or OID returns only 2 IPs even though multiple IPs are configured:

server-host% snmpwalk -v 2c -c '***' pnq16-co-agg-r2 IP-MIB::ipAdEntAddr
IP-MIB::ipAdEntAddr.10.130.96.4 = IpAddress: 10.130.96.4
IP-MIB::ipAdEntAddr.10.130.96.65 = IpAddress: 10.130.96.65

Workarounds: None.

CSCwd26540

Headline: Enable syslog for CRC Error on internal ports of TOR.

Symptoms: Below syslog is only true for switches with Fabric. Currently the following message is printed only for EOR.

2021 May 24 06:49:34 RTBE-14P6Z4Y16-7-13-BDR1 %STATSCLIENT-SLOT1-2-STATSCL_CRIT: Module 1 received CRC errors on internal interface ii1/1/3 in last ~5min interval FCSErr=3 TotalFCSErr=50518

Workarounds: None.

CSCwd27172

Headline: Unexpected reload after POAP process crashes.

Symptoms: Device reloads leaving a POAP core file:

2022 Oct 11 13:00:32 switch %$ VDC-1 %$ %SYSMGR-2-SERVICE_CRASHED: Service "poap" (PID 847) hasn't caught signal 11 (core will be saved)

Workarounds: Reduce the bootfile-url length to be less than 128 characters.

CSCwd29257

Headline: IPv6 OSPF ECMP route does not show both routes as best.

Symptoms: IPv6 OSPF ECMP route does not show both route with "*" as best, only one shows with "*" as best, so route from one neighbor is showing up with "*" and route from another neighbor is not.

Workarounds: Clear the IPv6 route as follows:
#clear ipv6 route 2001:fb1::/48

CSCwd33062

Headline: PIM source-register loopback is not honored for data encapsulated register packets.

Symptoms: PIM register packets generated by the DR with data encapsulated that are forwarded towards the RP do not honor the configured source-register configuration, and instead use the local interface/DR where the traffic was originally received as the outer header. The issue is not seen for null register packets that do not contain encapsulated data. On RP, the incorrect packet is seen under the show ip pim internal event-history data-register-receive command.

Workarounds: Remove the associated interface and register-source from the configuration and reapply it. Data-encap register then honors the register-source. However, this workaround does not survive the reload.

CSCwd41354

Headline: The grpcnxsdk works thread is not released properly.

Symptoms: There exists an ongoing gnmi 5-second sample subscription for “System/ptp-items/ephoper-items/pastcorrections-items/PtpEphCorrection-list”. The gNMI SET cannot happen when this path is being queried. The repetitive queries of this path at every 5 seconds triggers a bug, which prevents the query from completing. Then a following gNMI SET is blocked due to this unfinished query. The client script times out and sends more SET requests, which only piles up and uses up the max 16-session limit.

Workarounds: Kill the grpcnxsdk process. It recovers automatically and further queries can be made.

CSCwd42595

Headline: Output of the show spanning-tree root command no longer shows "This bridge is root" for non-vPC VLANs.

Symptoms: When upgrading to Cisco NX-OS Release 9.3(10), the output of the show spanning-tree root command does not indicate if the bridge is root for non-vPC VLANs. Additionally, on both vPC peers, the Bridge ID uses the local system-mac in place of the vPC system-mac. The cost and port is seen as 0 in the output of the show spanning-tree vlan command.

Workarounds: None

CSCwd45954

Headline: IOFPGA is not displayed during EPLD upgrade.

Symptoms: After EPLD upgrade from Cisco NX-OS Release 7.0(3)I7(3) to 9.3(9), few 9788TC modules show expected behavior, whereas 5-6 9788TC is not upgraded correctly. Additionally, the output of the show install all impact command shows both MI and IO FPGA in Cisco NX-OS Release 7.0(3)I7(3). However, in Cisco NX-OS Release 9.3(9), only MI FPGA is seen.

Workarounds: None.

CSCwd46673

Headline: [NX-OS] Cisco Nexus 9000 Back Pressure Correction to prevent PSU Fan Reverse Direction.

Symptoms: Power supply exhaust fan is observed to be spinning in wrong direction in a Cisco Nexus 9000 product.

Workarounds: Increase the PSU fan speed to prevent back-pressure.

CSCwd46964

Headline: Issue with configuring BFD RX interval, the BFD session seems to always use 50 ms as TX interval.

Symptoms: When configuring the BFD RX Interval, the BFD echo packets still transmit at 50 ms which is the minimum TX Interval. The inference is that the required RX interval which is configured using the bfd echo-rx-interval 250 command under the interface is not taken into account.

Workarounds: Use the bfd interval 250 min_rx 250 multiplier 3 command to specify the BFD TX interval.

CSCwd47148

Headline: Smart licensing - Callhome HTTP proxy is not working when defined using IPv6 address.

Symptoms: Communication with CSSM portal is not working when using IPv6 HTTP proxy.

Workarounds: Instead of referencing the HTTP proxy using IPv6, use HOSTNAME and define the static IPv6 host configuration.

CSCwd49931

Headline: Cisco Nexus 3000/Cisco Nexus 9000 BCM - ACL TCAM Mismatch is seen in hardware.

Symptoms: Mismatch on multiple entries in ACL TCAM is seen on Cisco Nexus platforms such as 3172PX.

Workarounds: None. The mismatch does not have any impact.

CSCwd49994

Headline: Static NAT stopped working after upgrade to 9.3(8).

Symptoms: After upgrading (disruptive ISSU) the Cisco Nexus switch from Cisco NX-OS Release 9.3(4) to 9.3(8), static NAT stopped working. Removing the NAT configuration and disabling the NAT feature and reconfigure it again does not help, not even reload/reload ASCII.

Workarounds: SMU patch will be available for the NX-OS 9.3(8) as workaround to fix the issue.

CSCwd53084

Headline: Cisco Nexus 9000 - SNMP does not return any value.

Symptoms: SNMP get/walk to Cisco Nexus 9000 might stop working and return empty values or OID may not exist even if OID is present and populated on the system. This issue may occur after several weeks or months of operation in Cisco NX-OS Release 9.3(5) and later.

Workarounds: Restart the SNMP process. However, if the issue repeats after restart, then restart again.

CSCwd54117

Headline: IPv6 ssh is not getting denied for default port 22.

Symptoms: This issue is observed in Cisco NX-OS Release 9.3(7) and 10.2.4(M). There is no command to change ssh port number in Cisco Nexus CLI syntax. However, ssh port number can be changed in bash mode.

Workarounds: None.

CSCwd56148

Headline: Cisco Nexus 9000 crashes with tahusd core.

Symptoms: After upgrading from Cisco NX-OS Release 9.3(5) to Cisco NX-OS Release 9.3(10), the switch crashes with tahusd core with the following Syslog entries.

%$ VDC-1 %$ %SYSMGR-SLOT1-2-SERVICE_CRASHED: Service "tahusd" (PID 25045) hasn't caught signal 6 (core will be saved). %$ VDC-1 %$ %SYSMGR-SLOT1-2-HAP_FAILURE_SUP_RESET: Service "tahusd" in vdc 1 has had a hap failure <<<

The tahusd process crashes due to any one of the following reasons:

Workarounds: None

CSCwd63552

Headline: There is a mismatch between the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide and the threshold configured on the switch.

Symptoms: Per the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide, Release 9.3(10), the switch supports 48000 STP instances. However, the devices trigger a log message when more than 14000 are in use.

Workarounds: None.

CSCwd64423

Headline: Fill word IDLE not reported correctly in the output of the show hardware internal fc-mac all-ports command.

Symptoms: This is a show command output error. The value is displayed incorrectly.

Workarounds: None. However, no functional impact.

CSCwd66084

Headline: N9K-C9364C-GX - Removing SFP-10G from one port causes other ports in the same quad to flap.

Symptoms: When the quad speed is 100G (when 100G optics are inserted in the port in the quad), inserting and then removing the SFP-10G causes other ports which are in same quad to flap. This issue only occurs when removing SFP-10G. This issue is not seen when removing 40G SFP.

Workarounds: None

CSCwd67745

Headline: Cisco Nexus 9000 switch crash when tunnel-encryption and speed 10000 is configured on the same interface.

Symptoms: When tunnel-encryption and speed 10000 is configured on the same interface, tahusd crashes, resulting in boot loop on switch startup.

Workarounds: Do not manually set speed to 10000 or use QSA.

CSCwd68610

Headline: Cisco Nexus 9000 mrib hap reset.

Symptoms: Cisco Nexus 9000 running Cisco NX-OS Release 9.3(10) code has an unexpected reload and generates core dumps for mrib and mcastfwd process.

Workarounds: None.

Headline: KIM crashes with egress_vni >512 entries.

Symptoms: KIM process crashes after configuration change.

Workarounds: None.

CSCwd85014

Headline: Unexpected reload due to tahusd process crash.

Symptoms: A Cisco Nexus 9000 switch may reboot unexpectedly due to tahusd process crash and a reset reason and an error log are generated.

Workarounds: None.

CSCwd95021

Headline: After the current interface is shutdown, the incoming interface is not updated in the multicast mroutes table.

Symptoms: Issue with multicast mroutes table not updating the incoming interface of multicast group after shutting down the current interface and still pointing to the one which is shutdown. This issue is seen in the Cisco NX-OS Release 9.3(10) code, whereas works fine in the Cisco NX-OS Release 9.3(9) code.

Workarounds: None.

CSCwe05630

Headline: NXA-PAC-650W PSU is reported as shutdown but is still operational.

Symptoms: Power supplies (including, but not limited to NXA-PAC-650W-PE/PI or NXA-PAC-500W-PE/PI) are reported as shutdown while continuing to operate normally per the show environment power detail command.

During the issue, the OK LED is seen to be either green or flashing green, and the Fault LED is seen to be off.
