Configuring and Enabling RADIUS

authenticate users; if that method fails to respond, the software selects the next authentication method

in the method list. This process continues until there is successful communication with a listed

authentication method or until all defined methods are exhausted. If authentication fails at any point in

this cycle—meaning that the security server or local username database responds by denying the user

access—the authentication process stops, and no other authentication methods are attempted.

Beginning in privileged EXEC mode, follow these steps to configure login authentication. This

procedure is required.

Command Purpose

Step1 configure terminal Enter global configuration mode.

Step2 aaa new-model Enable AAA.

Step3 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 more

information on list names, click this link:

•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:

•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.

•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 13-5.

Step4 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.

Step5 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

Step6 radius-server attribute 32

include-in-access-req format %h

Configure the access point to send its system name in the NAS_ID

attribute for authentication.

Step7 end Return to privileged EXEC mode.

Step8 show running-config Verify your entries.

Step9 copy running-config startup-config (Optional) Save your entries in the configuration file.
