aaa authentication

[ben robin]

I am trying to connect to a switch in a network through the console but being prompted with local user authentication, but I would like to configure it to authenticate through aaa radius

You can't configure radius for local or remote access to console or TTY lines.  For that you need ACS. ACS server can be a physical device or a VM.

I remember reading somewhere that AAA is not permitted on the console by default. This was done to prevent a lockout due to some mis-configuration of aaa

There is a hidden command, something like aaa authentication console, which will enable it if you really want to do it
