Headline: Cisco NX-OS HSRP stuck in "Initial" state after reload with static HSRP MAC configured

Symptoms: - For Nexus broken VLAN 2251 with static HSRP MAC is configured, after reload HSRP gets stuck in "Initial" state, but should move to next states as seen for working VLAN 2250.

Workarounds: -Shutdown/no shutdown SVI VLAN 2251 (or impacted HSRP VLAN) will move the HSRP state out of "Initial" and continue to next state eventually transitioning to Standby or Active as expected.-Temporary fix would be to use any MAC not in this range 0000.0C9F.xxxx. However, HSRP MAC range is 0000.0C9F.Fxxx which we anyway cannot configure statically for a group.

Known Issues

 

Bug ID                    

Description

CSCvi73973

Error message is seen rarely when a huge file (greater than 1GB) is copied to the USB first time after reload.

There is no functional impact to the copy command itself.

CSCvj74453

If you enable and disable a feature using a script in one VSH terminal session and execute those feature related commands in another terminal session, the behavior is unpredictable. Configuring and deleting the same parser chain in multiple VSH sessions is not supported. You must refrain from entering feature specific show CLI commands from a different VSH session when the same feature is being disabled in another terminal session.

Doing so might even result in a VSH crash. There is no functional impact or SSO or reload due to this crash.

CSCvp19886

During re-key when conf_offset for a macsec policy is updated dynamically, packet drop for ~100ms is observed. This is a known hardware limitation.

CSCvx05248

When running debug tool, ethanalzyer autostop duration does not work and does not automatically stop the packet capture. This is an expected behavior.

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.
