Sep 01, 2020

Products (1)

  • Cisco Catalyst 9200 Series Switches

Known Affected Releases

16.12.3

Description (partial)

Symptom:
Unexpected reboot- A fed core file should be generated in a system-report file

Last reload reason: Critical process fed fault on fp_0_0 (rc=139)

Conditions:
" ip nbar " or any other feature which causes WDAVC to be configured in a layer 2 trunk port.

In order to confirm CSCvu84365, you can execute " show logging process fed internal | i wdavc " and you should see errors like the following:

[asic_nfl] [11472]: (ERR): AFD-INFRA:NFL wdavc search failed with key:? -- > Search failure

NOTE: WDAVC is not supported in layer 2 trunk ports. In software versions including the ones with fix for CSCvu84365, the box will not experience an unexpected reload but continuous search failures will continue to happen because DWAVC is no supported in layer 2 trunk ports
