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 used only if the previous
method returns an error, not if there is an authentication failure. Only the
RADIUS or TACACS+ methods can return an error. To ensure that the
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.
NOTE: Auth-Type:=Local doesn’t 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 authentication login.
console(config)# aaa authentication login default
radius local enable none
radius Uses the list of all RADIUS servers for authentication.
tacacs Uses the list of all TACACS+ servers for authentication.
