AAA Authentication
Dell Networking OS 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
login authentication. With AAA, you can specify the security protocol or mechanism for different login
methods and different users. In Dell Networking OS, 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
Dell Networking OS Command Reference.
