Added CSCwh50989 to Open Issues.

December 18, 2023

Cisco NX-OS Release 9.3(13) became available.

CSCvx62127

Headline: LICMGR crashes continuously and device reboots post issuing cli "sh lic all".

Symptoms: On upgrading the licmgr crashed continuously four times and hap_reset is triggered causing DUT to reboot. This happened on execution of CLI : "show license all"

2021 Mar 9 09:01:38 switch %$ VDC-1 %$ %SYSMGR-2-SERVICE_CRASHED: Service "licmgr" (PID 20292) hasn't caught signal 11 (core will be saved).

2021 Mar 9 09:01:38 TECTAE-PGBL-89 %$ VDC-1 %$ %SYSMGR-2-SERVICE_CRASHED: Service "licmgr" (PID 28524) hasn't caught signal 11 (core will be saved).

2021 Mar 9 09:01:38 TECTAE-PGBL-89 %$ VDC-1 %$ %CALLHOME-2-EVENT: SW_CRASH

2021 Mar 9 09:01:39 TECTAE-PGBL-89 %$ VDC-1 %$ %SYSMGR-2-SERVICE_CRASHED: Service "licmgr" (PID 28606) hasn't caught signal 11 (core will be saved).

Workarounds: Change the host name so that it does not have any special characters.

CSCwf54392

Headline: The "radius-server key <>" missing after ND ISSU.

Symptoms: When upgrading a Nexus 9000 switch from a code where LXC boot mode is not the default mode, to one where it is, using non-disruptive ISSU, the "radius-server key 7 <string>" configuration can go missing. This is due to to the change in default boot mode.

Workarounds: Remove and reapply the missing CLI string to reconfigure and ensure it is consistent between configuration and DME.

CSCwf08452

Headline: Lag in entering commands in 93360YC-FX2.

Symptoms: Most of the ports on these switches are populated with GLC-TE Transceivers.  Any changes to the port configurations usually cause very long delays (minutes). This could be from a 'switchport' or 'shut/no shut' command.

Have experimented with 'spanning-tree port type edge' and explicitly setting the speed on the port, but issues are still occurring. The switch also seems to take a very long time to recognize a new physical connection or GLC-TE reseat. GLC-TEs are supported on this model according to the matrix page.

Workarounds: Use ‘no QOS statistics’.

CSCwf37269

Headline: Nexus 9000 Cloud Scale switches with mix of static and dynamic queue-limit drops low-rate traffic.

Symptoms:

1. Egress interface reports incrementing output discards despite a low rate of traffic destined for that interface.

2. Incrementing occupancy drops under PG-Drop pool (slot X show hardware internal tah buffer counter).

3. The queue depth remains at 0 byte for the affected Egress interface (show queuing interface), which means that there is no actual congestion for that interface.

4. When sufficiently *reducing* the static queue-limit configuration or the number of ports configured with static queue-limit, under the same traffic conditions, output discards for the affected interface stop.

Workarounds: Use ‘dynamic queue-limits’.

CSCwh02830

Headline: Manual power cycle required after upgrading N9K-C9500 switch NXOS EPLD with SUP A+/SUP B+ V02

Symptoms:

1. Nexus 9500 chassis with single or dual SUP A+ or B+ HW V02

2. Upgrade of Sup or SC EPLD (Just NXOS upgrade will not trigger this issue.)

3. After the reload, the active SUP module does not boot up all the way and appears to be stuck with no console output and a continuously blinking amber STS LED.

Workarounds:

1. Physically re-seat the module (cold power-cycle).

2. Remove all power to the chassis to allow the SUP module to power up again.

CSCwh72222

Headline: ARP request dropped by ARP Suppression in traditional VLAN

Symptoms: ARP requests of hosts in a Non-VXLAN VLAN are dropped in the VTEP switch due to ARP suppression.

Additionally, ARP request packets can be captured in CPU with Ethanalyzer tool, even though the VLAN does not have an SVI.

Workarounds:  Configure an SVI for the affected VLAN. SVI can be shut down and does not need an IP address or reload the switch.

CSCwd13172

Headline: Nexus 9000 FX2 multicast-tx span is not working.

Symptom:

1.     Multicast traffic is not mirrored from the configured source interface or

2.     Multicast traffic would be mirrored from incorrect source interface or

3.     Not a configured interface.

Workarounds: None

CSCwi45695

Headline: During BIOS downgrade, N9K-X96XX modules may experience time-out.

Symptom: BIOS downgrade for N9K-X96XX linecard modules may report failure due to time-out.

Module 3: Refreshing compact flash and upgrading bios/loader/bootrom.

Warning: please do not remove or power off the module at this time.

[####################] 100% -- FAIL.

Return code 0x40820011 (Job timedout).

CAUTION: The BIOS/loader/bootrom of above module may be in corrupted state. Please try programming it again.

Workarounds: If 'show install all impact ...' indicates a lower BIOS version than that currently installed on the module, avoid using the 'bios-force' flag during install operations.

CSCwi44292

Headline: Pre-upgrade check on nxos64-msll images does not display new BIOS version correctly during downgrade.

Symptom: During downgrade from impacted NXOS version to a previous version, pre-upgrade check displays New BIOS version as blank on following impacted platforms

Impacted Software version:10.4(2),9.3(13)

Impacted Platforms:

-N3K-C36180YC-R

-N9K-X96XX  with N9K-X9636Q-R,N9K-X9636C-RX, N9K-X9624D-R2,N9K-X96136YC-R line cards

Workarounds: None

CSCwi36291

Headline: QSFP-100G40G-BIDI higher linkup time issue

Symptom: Sometimes link up time may be higher on N9K-C9364C (port 49-64) or N9K-C9332C (port 25-32) when using QSFP-100G40G-BIDI optics.

Workarounds:  Use other ports on these PIDs or switch to another type of optics.

CSCwh50989

Headline: Custom COPP causing transit traffic to be punted to the CPU on Nexus 9300-GX2

Symptoms: When custom-COPP policy contains ACL rules which match on Layer 4 destination or source port, transit traffic also hits the COPP and the packets are copied to CPU. This causes duplication of traffic as CPU also routes the copied packets to the destination.

Workarounds: Custom COPP policy using src/dst match mitigates punt for transit traffic.

CSCwa86549

Headline: Nexus 9000 M1100 sees I/O error, goes read-only then leaf crashes

Symptoms: Dmesg reports I/O errors followed by remounting the filesystem as read-only:<3>[xxx] Buffer I/O error on device sda4, logical block 0   <4>[xxx] lost page write due to I/O error on sda4   <2>[xxx] EXT4-fs error (device sda4): ext4_journal_check_start:56: Detected aborted journal   <2>[xxx] EXT4-fs (sda4): Remounting filesystem read-only   <3>[xxx] EXT4-fs (sda4): previous I/O error to superblock detected   <6>[xxx] sd 1:0:0:0: [sda] Unhandled error code   <6>[xxx] sd 1:0:0:0: [sda]   <6>[xxx] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK  The switch can then proceed to crash due to going read-only

Workarounds: Reloading the switch should bring it back to full operation

CSCwd53591

Headline: Silent Reload due to watchdog timeout

Symptoms: Silent Reload due to watchdog timeout

Workarounds: No valid workaround so far

CSCwf10364

Headline: kmalloc fail due to SSD writes causing memory frag/higher order page depletion

Symptoms: Kmalloc failures due to excessive fragmentation

Workarounds: Observe from buddyinfo:cat /proc/buddyinforun bashsync && echo 3 > /proc/sys/vm/drop_cachesecho 1 > /proc/sys/vm/compact_memoryIf the above doesn't work then reload box

CSCwf40750

Headline: N9K C9336C-FX2 9.3(8) crashed while adding port channel to physical port

Symptoms: Unexpected reload happened when adding port channel to physical port.Tahusd core file decode mentions functions related to adding a member to a port channel.The decode is not matching any from our known bugs.

Workarounds: No workarounds known

CSCwf48692

Headline: N9300-FX3S/FX3 may randomly timeout syncE peer

Symptoms: Random syncE peer timeouts.

Workarounds: N/A

CSCwf58507

Headline: FEX 2348UPQ brings hosts link too fast after powercycle causing traffic blackholing for around 1min.

Symptoms: when FEX 2348TQ power-cycles all hosts using (GLC-T, GLC-T-C,SFP-H10GB-CU3M,SFP-H10GB-CU3M) SFPs will have link up while the FEX is down. after ~5 seconds links go up for around 1 minute, despite the fact that FEX from N9k perspective and its FIs are down.

Workarounds: Use LACP or any other SFP or upgrade the version.

CSCwf82223

Headline: On N9K switch SNMP polling unable to retrieve QSFP DOM values.

Symptoms: A third patry DOM supported QSFP will not provide any DOM information when polled via SNMP.

Workarounds: Physically reset QSFP28. OIR.

CSCwf93175

Headline: FIB and RIB become inconsistent after EIGRP route switchover

Symptoms: When there are two EIGRP processes, if the route switchover occur due to a linkflap, the FIB and RIB become inconsistent.

Workarounds: clear ip route x.x.x.x/x

CSCwf97335

Headline: N9k | Host routes transition with Punt index in v4host table after route change

Symptoms: Multiple Symptoms may be reported.1) Traffic to certain IP addresses may end up having high response times or2) Intermittent packet loss to certain HostsCoPP Drops may be seen depending upon the traffic rate for the class- copp-system-p-class-l3uc-dataData plane traffic to these impacted hosts are software switched/punted and is visible via Ethanalyzer.

Workarounds: Introduce back the AM or /32 Host routes

Headline: After reload of 93108TC-FX3P random copper/RJ45 interfaces might not come up

Symptoms: After reload of 93108TC-FX3P device some RJ45 interfaces might not come up. This can happen with any reload reason (power up/down, upgrade, SW reset, crash). Issue is related only to the front panel interfaces Ethernet 1/1-48 (MGMT port is not affected)

Workarounds: FPGA upgrade

CSCwh94363

Headline: BGP routes stuck in stale for shutdown BGP neighbor

Symptoms: BGP neighbor is in Shut (Admin) StateBGP table shows all routes in a Stale and Best state from the neighbor that was shutdownURIB shows route still learned via the BGP peer that is shutdown

Workarounds: 1- bringing back up the BGP neighbor - Routes are refreshed and work2 - restart BGP process. DO NOT WORK - clear bgp ipv4 un * softclear ip route X.X.X.X/Y

CSCwi28438

Headline: Rapid mac flaps caused by Server NIC teaming failover will cause ARP table and CAM table out of sync

Symptoms: Server is connected to a pair of Nexus 9K Broadcom switches over Non-VPC HIF FEX ports. When a Nexus 9000 has 10 mac flaps under 1 second. Mac learning for that vlan will be disabled for 120 seconds. The egress interface entry for ARP and mac address table may point to different ports. When mac learning is re-enabled, the egress interface for the ARP entry may not update to the new interface. This may occur when a host with nic teaming transitions between active-standby to active-active and back.

Workarounds: 1) Clear the ARP entry2) Send an arp request on the previous port and then another one on the new port

CSCwf89997

Headline: Unexpected reload ipfib hap reset

Symptoms: Symptoms: During AM adjacency update, sometimes, the reprogramming of MPLS adjacencies goes in a loop and the system crashes.

Workarounds: None

CSCwf25135

Headline: MSDP peer is flapping

Symptoms: MSDP performance issues may be observed if it's running in a VRF that's not enabled in BGP while BGP is configured globally.- Adjacencies may flap due to keepalives expired, while packet captures indicate no drops- SA propagation may be significantly delayed, or SAs may never be received- The receive queue for MSDP TCP sockets in "show sockets connection" would be full

Workarounds: Enable the MSDP VRF under the BGP process. No additional configuration such as address families or neighbors is required.
router bgp 65500 vrf MSDP-VRF
Alternatively, disable BGP entirely: no router bgp 65500

CSCwh42690

Headline: Netstack crash when punting IPV6 packet with IPV6 destination option larger than 56 bytes

Symptoms: In an MPLS environment, the device that punts the IPV6 MPLS packet (with an extension header of greater than 56 bytes) to SUP experiences netstack crash or device reload

Workarounds: Stop sending packets that get punted to CPU such as traceroute probes that might have these options enabled.

CSCwa96146

Headline: Cisco NX-OS Release 10.1(1) does not set TACACS+ Single-Connect Flag with CLI enabled.

Symptoms: Customer is trying to implement TACACS+ "single-connect" mode, and it is not working correctly.

Workarounds:

-      Use Cisco TACACS+ servers (ISE) which have a check box for "enable single connect mode" and "Legacy devices". This will make the server function in single connect mode, and will not check for the flag in TACACS+ headers.

-      Disable Single-Connection mode.

-      Remove CLI from NX-OS

CSCwb90675

If a EOR gets stuck while configuring monitor scale at flow system configuration, try the following workaround:

-      Save current running config to bootflash, other local file system or USB.

-      Reload ascii

-      Reload switch.

-      Do a SUP system switchover (SSO).

CSCwe74517

When you remove template peer-policy under l2vpn EVPN address-family it deletes the prefixes. The workaround is to reconfigure the affected neighbor or restart BGP.

CSCwh49061

VLAN Mapping: strict incompatibility during downgrade from 10.3.x to 9.3.x.
VLAN Mapping commands need to be removed when you downgrade from 10.3.x to 9.3.x versions. Workaround is to remove switchport vlan mapping command and add it again after the downgrade.

CSCwi35215

If a single mac address moves more than 10 times in a second, then mac learning would be disabled on corresponding vlan for 120 seconds. This is a known limitation.

CSCwi15483

Interface is up without cable, only QSFP is inserted: Interface will not go down when the link is shut on the remote side and even after removing the cable interface is still up. This is a known limitation.
