Monitoring AAA Accounting 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 Dell# 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 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 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. NOTE: In the release 9.4.(0.0), RADIUS and TACACS servers support VRF-awareness functionality. You can create RADIUS and TACACS groups and then map multiple servers to a group. The group to which you map multiple servers is bound to a single VRF. Configuration Task List for AAA Authentication The following sections provide the configuration tasks. • Configure Login Authentication for Terminal Lines • Configuring AAA Authentication Login Methods 160 Security
