Prerequisites for Configuring ISG Integration with SCE
Hardware Requirements
-
An SCE platform
-
Two connections between the ISG device and the SCE: - A control path, through which the ISG device and SCE can exchange policy information

-
A policy server configured to communicate with the ISG platform. The ISG-SCE integration removes any need for a communication layer between the policy server and the SCE.

-
Cisco Software Release 3.1.0 or later on the SCE
