In the Dell Force10 implementation, the Dell Force10 system acts as a 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. 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. 784 | Security
