Configure AAA Authentication for Roles

Authentication services verify the user ID and password combination. Users with defined roles and users 
with privileges are authenticated with the same mechanism. There are six methods available for 
authentication: radius, tacacs+, local, enable, line, and none.

When role-based only AAA authorization is enabled, the enable, line, and none methods are not 
available. Each of these three methods allows users to be verified with either a password that is not 
specific to their user ID or with no password at all. Because of the lack of security these methods are not 
available for role only mode. When the system is in role-only mode, users that have only privilege levels 
are denied access to the system because they do not have a role. For information about role only mode, 
see 

NOTE: Authentication services only validate the user ID and password combination. To determine 
which commands are permitted for users, configure authorization. For information about how to 
configure authorization for roles, see 

To configure AAA authentication, use the aaa authentication command in CONFIGURATION mode.
aaa authentication login {method-list-name | default} method [… method4]
