Configuring ISG Subscriber Services
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.
ISG defines a service as a collection of policies that can be applied to any subscriber session. This
module describes how ISG subscriber services work, how to configure services and traffic classes that
may be used to qualify policies defined within a service, and how to activate services.
