Aaa Authentication; Configuration Task List For Aaa Authentication - Dell C9000 Series Networking Configuration Manual

Monitoring AAA Accounting
The system does not support periodic interim accounting because the periodic command can cause heavy
congestion when many users are logged in to the network.
No specific show command exists for TACACS+ accounting.
To obtain accounting records displaying information about users currently logged in, use the following
command.
• Step through all active sessions and print all the accounting records for the actively accounted functions.

AAA Authentication

The system 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 switch acts as a RADIUS or TACACS+ client and sends
authentication requests to a central remote authentication dial-in service (RADIUS) or Terminal access
controller access control system plus (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 the 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.
NOTE: If a console user logs in with RADIUS authentication, the privilege level is applied from the RADIUS
server if the privilege level is configured for that user in RADIUS, whether you configure RADIUS
authorization.
