Cause

Dette skyldes et Cisco Defect ID-CSCWK43183, der påvirker NX-OS 9.4.1a.

Resolution

I NX-OS version 9.4(1a) er outputtet fra show users -kommandoen vises konsekvent den 1. januar sammen med tidsforskydningen fra UTC baseret på den konfigurerede tidszone.

Siden show users output viser et forkert tidsstempel, show accounting log Kan kontrolleres for det seneste login-tidsstempel for admin-brugeren.

Løsning: 
When a user logs in to the switch on SSH, accounting log records the login of the user as below:
<timestamp> :type=start:id=10.138.65.80@pts/1:user=admin:cmd=
 
When a user logs into the switch on console, accounting log records the login of the user as below:
<timestamp> :type=start:id=console0:user=admin:cmd=
 
To view the last logged in time for a user named "admin", run the below command:
 # show accounting log | grep "start.*admin" | tail lines 1

Reparere:
Opgrader til NX-OS 9.4.2-versionen.

Seddel:
Før du opgraderer til 9.4.2, skal du kontrollere, om TACACS anvendes som godkendelsesprotokol i dine switche.
  • Hvis ja, kan Cisco-defekt CSCWK14579 forårsage godkendelsesfejl efter opgraderingen til 9.4.2. Deaktiver derfor TACACS, og udfør firmwareopgraderingen. Aktivér derefter TACACS-konfigurationen.
  • Hvis switchene ikke bruger TACACS til godkendelse, kan du opgradere til 9.4(2) uden problemer.
