Accounting.
RADIUS accounting on the Series 2500 switches collects resource consumption data
and forwards it to the RADIUS server. This data can be used for trend analysis, capacity planning,
billing, auditing, and cost analysis.

RADIUS Server:
A server running the RADIUS application you are using on your network. This

necessary information to the switch. For the Switch 2512 and 2524 a RADIUS server can also perform
accounting functions. Sometimes termed a RADIUS host.
