ISE/MSS-G integration uses TrustSec data from Cisco ISE to create an MSS-G configuration to distribute to switches via CloudVision. The integration is implemented by an ISE provider that runs in the third-party collector. It maps TrustSec Security Groups (SGTs), Access Control Lists, and policies into MSS-Segments and policies.The integration is built on top of Cisco ISE’s External RESTful Services (ERS) and pxGrid APIs. Most of the integration is based on pxGrid and some information that is not available through pxGrid is loaded using the ERS REST APIs.
