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 specic 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 dierent login methods and dierent users. In the Dell Networking OS, AAA uses a list
of authentication methods, called method lists, to dene the types of authentication and the sequence in which they are applied. You can
dene a method list or use the default method list. User-dened 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 congured for that user in RADIUS, whether you congure RADIUS authorization.
Conguration Task List for AAA Authentication
The following sections provide the conguration tasks.
• Congure Login Authentication for Terminal Lines
• Conguring AAA Authentication Login Methods
• Enabling AAA Authentication
• Enabling AAA Authentication—RADIUS
For a complete list of all commands related to login authentication, refer to the Security chapter in the Dell Networking OS Command
Reference Guide.
