AAA Authentication

FTOS supports a distributed client/server system implemented through Authentication, Authorization, and

Accounting (AAA) to help secure networks against unauthorized access. In the Dell Networking

implementation, the Dell Networking 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 Networking uses local usernames/passwords (stored on the Dell Networking system) or AAA for

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.
