Setup Guide

NAS receives the accounting request from the supplicant and sends the RADIUS request packet to the accounting server after successful
authentication. The RADIUS Accounting request contains a RADIUS Acct-Status-Type as Start or Stop to update the supplicant session
to the accounting server.
NOTE: In RADIUS accounting, fallback behavior among RADIUS and TACACS servers is not supported as the RADIUS
accounting feature is not available in Dell EMC Networking OS version earlier than 9.14.1.5.
In VLT domain, the NAS sends the RADIUS Accounting Request packets only if the NAS is congured as a VLT primary peer.
Congure RADIUS Accounting
The NAS monitors the accounting functions dened in the RADIUS Accounting attribute/value (AV) pairs.
• Congure AAA accounting to monitor accounting functions dened in RADIUS.
CONFIGURATION mode
aaa accounting {dot1x | exec} default {start-stop | wait-start | stop-only} radius
Example of Conguring AAA Accounting to Track EXEC and EXEC Privilege Level Command Use
In the following sample conguration, AAA accounting is set to track all usage of EXEC commands and commands on privilege level 15.
Dell(conf)# aaa accounting dot1x default start-stop radius
Dell(conf)# aaa accounting exec default stop-only radius
