Cisco Cisco IOS Software Release 12.2(33)SRE

© 2007 Cisco Systems, Inc. All rights reserved.

The Per IP Subscriber DHCP Triggered RADIUS Accounting feature enables system administrators to 
track IP session activity on a per-subscriber basis and periodically extract subscriber accounting records. 
Transactions between the client and the RADIUS accounting server are authenticated via an Access 
Client module that maintains per-subscriber accounting statistics.

Per IP Subscriber RADIUS Accounting works with DHCP IP address assignment on Cisco 7600 series 
routers only, and it improves the authentication, authorization, and accounting (AAA) of broadband 
service delivery. Subscribers are attributed a unique AAA ID in addition to the unique ID created by 
DHCP in order to process secure START and STOP accounting messages and allow them to abstract 
accounting information in a client-server environment.
