Privileged EXEC
Usage Guidelines

Examples
The following is sample output from the debug aaa authentication command. A single EXEC login that
uses the “default” method list and the first method, TACACS+, is displayed. The TACACS+ server sends
a GETUSER request to prompt for the username and then a GETPASS request to prompt for the
password, and finally a PASS response to indicate a successful login. The number 50996740 is the
session ID, which is unique for each authentication. Use this ID number to distinguish between different
authentications if several are occurring concurrently.
