Bug ID

Description

CSCvx53013

Headline: Unsupported TCAM region config added when ISSU from 9.2.4 to 9.3.4

 

Symptoms: Following lines exist in running-config and cannot be removed:

hardware access-list tcam region ing-racl-lite 534756472 double-widehardware access-list tcam region ing-short 189402400 double-widehardware access-list tcam region ing-ifacl-ipv4-lite 1hardware access-list tcam region ing-ifacl-ipv6-lite 32784hardware access-list tcam region ing-cntacl 1hardware access-list tcam region ing-mvpn 370590546 double-widehardware access-list tcam region ing-l2-l3-qos 28hardware access-list tcam region hw-telemetry 1

 

Workaround: Perform write-erase followed by reload.

CSCvx60047

Headline: "no negotiate auto" is removed from RJ-45 member interface and not from PO

 

Symptoms: If a RJ-45 port is member of a port-channel, with "no negotiate auto" configuration on the port-channel and member interfaces, that configuration gets removed from the member interface, but not from the port-channel after ISSU from a pre-9.3(4) or pre-7.0(3)I7(8) image to later images.

 

"show running interface e<x/y>" would not have "no negotiate auto" config

"show running interface po<>" would have "no negotiate auto" config

"no channel-group <>" config on the member interface will not take effect

 

Workaround:
Workaround for Pre-ISSU:

   - Remove "no negotiate auto" config from port-channel interface with RJ45 ports

 

  Workaround for Post-ISSU (if the pre-ISSU workaround is not applied):

   - Remove "no negotiate auto" config from port-channel interface with RJ45 ports

   - Run "channel-group " config on all members again

CSCvx56768

Headline: 1G GLC-TE port was not coming up on N9K-C93360YC-FX2 after unplug and replug the SFP

 

Symptoms: Connect C2960X to Nexus 9000 with GLC-TE. Keep the connection up first and then unplug and replug the SFP on Nexus 9000  side. The port will not come up untill you shut /no shut the port on Nexus 9000 side.

 

Workaround: Shut /no shut the port on Nexus 9000 side.

CSCvx58626

Headline: SNMP Crash in Nexus 9000  after ISSU Upgrade

 

Symptoms: Nexus9000 C9504, supervisor "N9K-SUP-A" crashed in during no disruptive upgrade from 7.0(3)I4(7) to 7.0(3)I7(9) aborting the ISSU.

 

Workaround: None

CSCvx60909

Headline: Installing multiple SMUs do not remain committed after reload.

 

Symptoms: When installing multiple SMUs they do not remain committed after reload.

 

Workaround: Upgrade to a version that contains the fixes natively.

CSCvx61330

Headline: Nexus 9000 aclqos cores - ERSPAN w/source VLAN mapped to VNI on certain ports

 

Symptoms: Gen1 Nexus 9000 models may see a core file from the aclqos process when trying to do an ERSPAN on a VLAN mapped to a VNI, using ports from speicifc ASICs.

 

Workaround: None

CSCvx39125

Headline: Module ejector interrupt storm causing plfm mgr crash

 

Symptoms: Marginal seating of IO module can lead to ejector button driven interrupt storm which causes platform manager to crash.

 

Workaround: Reseat module to verify good connection, verify chassis grounding, etc.

CSCvx41778

Headline: BGP flaps (with holdtimer expired) every time a new leaf is added or reloaded

 

Symptoms: VXLAN spine and leaf mode on infrastructure of Nexus 93180YC works fine without any problem. The issue arises when reloading leaf X or introducing a new leaf, this will make that a random leaf of the network connected to same spines  loses BGP connection. This happens randomly, affecting different leafs.The evpn architecture implemented is based on a bgp ipv4 underlay, making it possible to announce the loopbacks of the Nexus serving as termination for the VTEPs.

 

Workaround: None

CSCvx59644

Headline: HW Multipath table is not programming some links.

 

Symptoms: Available paths seen on show ip route for equal cost paths are not being fully utilized.

 

Workaround: Bundle uplinks in L3 port-channel

CSCvx60023

Headline: MAC Mobility Seq is not updated correctly upon MAC moves

 

Symptoms: MAC Mobility sequence number is not correctly updated on EVPN routes when a host moves from one site to another.Missing the correct Sequence number might lead BGP to select non-optimum paths.

 

Workaround: None

CSCvx60758

Headline: Bringing up SPAN session silently fails when sFlow data sources are configured

 

Symptom: A Nexus 9000 series switch configured with sFlow data sources is not able to administratively bring SPAN sessions online. This is expected behavior and is a documented limitation. If at least one sFlow data source is configured, the SPAN sessions cannot be brought up. However, no error message or feedback is presented if one attempts to bring a SPAN session up while an sFlow data source is configured.

 

Workaround: There is no known workaround for this issue. This defect introduces an error message to the CLI of the switch when one attempts to bring a SPAN session up while sFlow data sources are configured on the switch.

CSCvx60778

Headline:  SPAN session administrative status becomes stuck when brought up alongside sFlow data sources

 

Symptom: A Nexus 9000 series switch configured with sFlow data sources is not able to administratively bring SPAN sessions online. This is expected behavior and is a documented limitation. If at least one sFlow data source is configured, the SPAN sessions cannot be brought up. However, if one removes all sFlow data sources from the switch's configuration and attempts to administratively bring the SPAN session up, the SPAN session will remain in a down state.

 

Workaround: Administratively shutting down the SPAN session (even though it's technically already administratively shut down), then attempt to bring it back up.

CSCvx61244

Headline: `udld disable` on breakout interfaces is removed from running configuration after upgrade

 

Symptom: UDLD operational on a 4x10G interface that was previously configured to have udld disabled.

 

Workaround:None

CSCvx61532

Headline: CFS HAP reset and core file during system switchover

 

Symptom: A Nexus 9500 switch on 7.0(3)I7(x) version may undergo a HAP reset and generate a core file on performing a system switchover.

 

Workaround: None

CSCvw67472

Headline: Nexus9300 unexpect options ( port 1 216 ) are set on show run all

 

Symptom: When configuring "hardware rate-limiter access-list-log XXX" the port 1 216  are set on show run all like below.

Workaround: Write erase and then reload the device.

CSCvx57409

Headline: BGP remote-as route-map will be delete after default afi

 

Symptom: The BGP neighbor remote-as route-map will be deleted after the default afi show running config neighbor 10.1.1.0/24 remote-as route-map CLI is run.

 

Workaround: This is not an issue. The route-map is actually in effect.

CSCvx60094

Headline: Random link flaps on N9K-C93108TC-EX with QSFP-4x10G-AOC

 

Symptom: Random L1 link flaps on N9K-C93108TC-EX with QSFP-4x10G-AOC

 

Workaround:Disable/blacklist/admin-down all not-connected/unused breakout ports to reduce the frequency of link flap.

CSCvx61314

Headline: N9k VXLAN - Non-Zero ESI value can result in blackholing.

 

Symptom: Example output:

aFor specific fan speeds see the Overview section of the Hardware Installation Guide.

b This switch runs with +1 redundancy mode so that if one fan fails, the switch can sustain operation. But if a second fan fails, this switch is not designed to sustain operation. Hence before waiting for the major threshold temperature to be hit, the switch will power down due to entering the fan policy trigger command.
