To specify the enable password as the user authentication method, run the following
command:
aaa authentication login default enable
(2) Using the line password to login
Use the aaa authentication login command with the line method keyword to specify the line
password as the login authentication method. For example, to specify the line password as
the method of user authentication at login when no other method list has been defined, enter
the following command:
aaa authentication login default line
Before you can use a line password as the login authentication method, you need to define
a line password.
(3) Using the local password to carry on the login authentication:
When you run aaa authentication login, you can use the keyword “local” to designate the
local database as the login authentication method. For example, if you want to specify the
local username database as the user authentication method and not define any other
method, run the following command:
aaa authentication login default local
For information about adding users into the local username database, refer to the section
"Establishing Username Authentication" in this chapter.
(4) Login Authentication Using RADIUS
Use the aaa authentication login command with the group radius method to specify RADIUS
as the login authentication method. For example, to specify RADIUS as the method of user
authentication at login when no other method list has been defined, enter the following
command:
aaa authentication login default group radius
Before you can use RADIUS as the login authentication method, you need to enable
communication with the RADIUS security server. For more information about establishing
communication with a RADIUS server, refer to the chapter "Configuring RADIUS."
