Chapter 13 Configuring RADIUS and TACACS+ Servers
Configuring and Enabling TACACS+
To disable AAA, use the no aaa new-model global configuration command. To disable AAA
authentication, use the no aaa authentication login {default | list-name} method1 [method2...] global
configuration command. To either disable TACACS+ authentication for logins or to return to the default
value, use the no login authentication {default | list-name} line configuration command.
Configuring TACACS+ Authorization for Privileged EXEC Access and Network Services
AAA authorization limits the services available to an administrator. When AAA authorization is
enabled, the access point uses information retrieved from the administrator’s profile, which is located
either in the local user database or on the security server, to configure the administrator’s session. The
administrator is granted access to a requested service only if the information in the administrator profile
allows it.
You can use the aaa authorization global configuration command with the tacacs+ keyword to set
parameters that restrict an administrator’s network access to privileged EXEC mode.
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:
• 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 into the database. Use the username
password global configuration command.
• tacacs+—Uses TACACS+ authentication. You must configure the
TACACS+ server before you can use this authentication method.
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.
Step 6
end Return to privileged EXEC mode.
