Configuring AAA Accounting for Terminal Lines

To enable AAA accounting with a named method list for a specific terminal line (where com15 and
execAcct are the method list names), use the following commands.
• Configure AAA accounting for terminal lines.
CONFIG-LINE-VTY mode
accounting commands 15 com15
accounting exec execAcct
Example of Enabling AAA Accounting with a Named Method List
Dell(config-line-vty)# accounting commands 15 com15
Dell(config-line-vty)# accounting exec execAcct

Monitoring AAA Accounting

The Dell Networking OS 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.
CONFIGURATION mode or EXEC Privilege mode
show accounting
Example of the show accounting Command for AAA Accounting
Dell#show accounting
Active accounted actions on tty2, User admin Priv 1
Task ID 1, EXEC Accounting record, 00:00:39 Elapsed, service=shell
Active accounted actions on tty3, User admin Priv 1
Task ID 2, EXEC Accounting record, 00:00:26 Elapsed, service=shell

AAA Authentication
The Dell Newtorking 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 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
