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 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.
