I am currenlty using Cisco ACS 3.0 and have noticed very strange logs under Reports,failed Attempts.
It is showing numerous failed attempts from username : azbycx to our 4 Core 6500 Catos Switches.
The caller-id field does not display a source ip address and these hits are happening every minute.
I have noticed that any passed or failed attempts to any catos switches does not provide a caller-id ip address in the report. Any ios attempts logs the ip address fine.
Any help would be appreciated. Even a way to log the catos switch to determine what is attempting to log into these 6500 switches.
