What is tnBadAuthPkts?
Counts packets from this AAA server containing an invalid authenticator or Message-Authenticator attribute, which usually means the shared secret configured on the switch doesn't match what the server is using. This is one of the first counters to check when authentication mysteriously fails despite correct credentials.
