Hence, authorizationcannot be used independent of authentication. However, if you have configured RADIUSauthorization and have not configured authentication, a message is logged stating this. Duringauthorization, the next method in the list (if present) is used, or if another method is not present, anerror is reported.To view the configuration, use the show config in LINE mode or the show running-configcommand in EXEC Privilege mode.Defining a AAA Method List to be Used for RADIUSTo configure RADIUS to authenticate or authorize users on the system, create a AAA method list.Default method lists do not need to be explicitly applied to the line, so they are not mandatory.To create a method list, use the following commands.Security 783
