This is simple! I'm missing something. Multiple 2651 routers with Tacacs authentication and authorization configured using 'default' list. thats fine, but want to add accounting.
Add the lines:
aaa accounting exec default start-stop group tacacs
aaa accounting commands 15 default start-stop group tacacs.
No logs are showing in ACS? The report is configured. I can get accounting for logging in via telnet but no commands. Show priv shows level 15?
