User Guidelines
The default and optional list names created with the aaa authentication
login command are used with the login authentication command. Create a
list by entering the aaa authentication login list-name method command for
a particular protocol, where list-name is any character string used to name
this list. The method argument identifies the list of methods that the
authentication algorithm tries, in the given sequence.
The additional methods of authentication are attempted only if the previous
method returns an error, not if there is an authentication failure. Only the
RADIUS, , local and enable methods can return an error. To
ensure that authentication succeeds even if all methods return an error,
specify none as the final method in the command line. For example, if none is
specified as an authentication method after radius , no authentication is used
if the RADIUS server is down. If specified, none must be the last method in
the list.
NOTE: Auth-Type:=Local does not work for recent versions of FreeRadius.
FreeRadius ignores the configuration if Local is used. Administrators should remove
Auth-Type=Local
and use the PAP or CHAP modules instead.
Example
The following example configures the default authentication login to attempt
RADIUS authentication, then local authentication, then enable
authentication, and then, if all the previous methods returned an error, allows
the administrator access to the switch console (via the none method).
console(config)# aaa authentication login default radius local enable none
tacacs Use the list of all servers for authentication.
