Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
aaa new-model
Enable AAA.
Step 3
aaa authentication login {default |
list-name} method1 [method2...]
Create a login authentication method list.
•
To create a default list that is used when a named list is not specified
in the login authentication command, use the default keyword
followed by the methods that are to be used in default situations. The
default method list is automatically applied to all interfaces.
•
For list-name, specify a character string to name the list you are
creating.
•
For method1..., specify the actual method the authentication
algorithm tries. The additional methods of authentication are used
only if the previous method returns an error, not if it fails.
Select one of these methods:
•
enable—Use the enable password for authentication. You must
define an enable password before you can use this authentication
method. Use the enable password global configuration command.
•
group radius—Use RADIUS authentication. You must configure the
RADIUS server before you can use this authentication method. For
more information, see the
“Identifying the RADIUS Server Host”
section on page 6-58
.
•
line—Use the line password for authentication. You must define a
line password before you can use this authentication method. Use the
password password line configuration command.
•
local—Use the local username database for authentication. You must
enter username information in the database. Use the username
password global configuration command.
•
local-case—Use a case-sensitive local username database for
authentication. You must enter username information in the database.
Use the username password global configuration command.
•
none—Do not use any authentication for login.
Step 4
line [console | tty | vty] line-number
[ending-line-number]
Enter line configuration mode, and configure the lines to which you want
to apply the authentication list.
Step 5
login authentication {default |
list-name}
Apply the authentication list to a line or set of lines.
•
If you specify default, use the default list created with the aaa
authentication login command.
•
For list-name, specify the list created with the aaa authentication
login command.
