Open Issues

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. ---hardware rate-limiter layer-3 glean 100 module 1 port 1 216hardware rate-limiter layer-3 multicast local-groups 3000 module 1 port 1 216hardware rate-limiter access-list-log 100 module 1 port 1 216hardware rate-limiter bfd 10000 module 1 port 1 216hardware rate-limiter fex 12000 module 1 port 1 216hardware rate-limiter span 50 module 1 port 1 216hardware rate-limiter sflow 40000 module 1 port 1 216hardware rate-limiter vxlan-oam 1000 module 1 port 1 216hardware rate-limiter 100M-Ethports 10000 module 1 port 1 216hardware rate-limiter DOT1X 3000 module 1 port 1 216hardware rate-limiter mpls-oam 300 module 1 port 1 216hardware rate-limiter netflow 120000 module 1 port 1 216---But it is not possible to even configure "... port 1 216" on the device.---switch# conf tEnter configuration commands, one per line. End with CNTL/Z.switch(config)# hardware rate-limiter layer-3 glean 100 module 1 port 1 216 ^% Invalid number, range is (1:48) at '^' marker.switch(config)# --- 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.

Workaround: Do not use ESI. ESI is not currently supported on Cloudscale platforms. For Nexus 9000 switches vPC can be used instead of ESI for dual homing and redundancy.
CSCvx50717	Headline: Nexus 9500 EX/FX SVI unicast counters do not work Symptom: Unicast SVI counters remain 0 in `show interface` and `show interface` and the `show vlan id X counters`. Workaround: None
CSCwe53655	Headline: Revert reserved MAC blocking behavior for VRRP macs on SVIs Symptoms: User is not able to configure VRRP VMAC on SVI interfaces. Workarounds: None.
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.

^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.
