In the Dell Force10 implementation, the system acts as a remote authentication dial-in service (RADIUS) or TACACS+ client and sends authentication requests to a central RADIUS or TACACS+ server that contains all user authentication and network service access information. Dell Force10 uses local usernames/passwords (stored on the Dell Force10 system) or AAA for login authentication. With AAA, you can specify the security protocol or mechanism for different login methods and different users. In FTOS, AAA uses a list of authentication methods, called method lists, to define the types of authentication and the sequence in which they are applied. You can define a method list or use the default method list. User-defined method lists take precedence over the default method list. Note: If a console user logs in with RADIUS authentication, the privilege level will be applied from the RADIUS server if the privilege level is configured for that user in RADIUS whether or not RADIUS authorization is configured. Configuration Task List for AAA Authentication The following sections provide the configuration tasks: • Configure Login Authentication for Terminal Lines • Configure AAA Authentication Login Methods • Enable AAA Authentication • AAA Authentication-RADIUS For a complete listing of all commands related to login authentication, refer to the Security chapter in the FTOS Command Reference Guide. Configure Login Authentication for Terminal Lines You can assign up to five authentication methods to a method list. FTOS evaluates the methods in the order in which you enter them in each list. If the first method list does not respond or returns an error, FTOS applies the next method list until the user either passes or fails the authentication. If the user fails a method list, FTOS does not apply the next method list. 476 | Security
