Subscriber Logon
First Published: March 20, 2006
Last Updated: March 2, 2009
Intelligent Services Gateway (ISG) is a Cisco IOS and Cisco IOS XE software feature set that provides
a structured framework in which edge devices can deliver flexible and scalable services to subscribers.
This module contains information on how to configure ISG to use specified identifiers in place of the
username in authorization requests, enabling a user profile to be downloaded from an authentication,
authorization, and accounting (AAA) server as soon as packets are received from a subscriber.
