Configuring ISG Port-Bundle Host Key
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 port-bundle host key functionality, which
maps TCP packets from subscribers to a local IP address for the ISG gateway and a range of ports. This
mapping allows an external portal to identify the ISG gateway from which a session originated.
