• A list-name character string identifies the authorization
method list. The method list itself follows the method
list name. Method list types are entered in the preferred
sequence. The listed method list types can be any one
of the following:
– none—The network access server (NAS) does not
request authorization information. Authorization
always succeeds. No subsequent authorization
methods will be attempted. However, the task ID
authorization is always required and cannot be
disabled.
– local—Uses local database for authorization.
– group tacacs+—Uses the list of all configured
TACACS+ servers for authorization. The NAS
exchanges authorization information with the
TACACS+ security daemon. TACACS+
authorization defines specific rights for users by
associating AV pairs, which are stored in a
database on the TACACS+ security server, with the
appropriate user.
– group radius—Uses the list of all configured
RADIUS servers for authorization.
– group group-name—Uses a named server group, a
subset of TACACS+ or RADIUS servers for
authorization as defined by the aaa group server
tacacs+ or aaa group server radius command.

Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
– Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
– Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
– Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
