Description

This command configures the router to use AAA to determine whether a user can access the privileged command set. The method parameter can be any of the following: enable, line, none, group tacacs+, or group radius. Each method describes where to get the password for authentication. If more than one method is listed, the methods are tried in order until one succeeds or all fail. This command does not work with TACACS or Extended TACACS (XTACACS).
