I am working on a large international ISE install that is going to use Passive ID to gather user to IP mapping to feed to FMC. They have upwards of 150 DCs. I know each PSN can only support 100 DCs. I have 5 PSNs spread around the globe running the passive ID service. My questions are:
I couldn't find a document detailing this, but may be missing it.
Thanks.

- How does ISE pick which PSN does the WMI probing to which DCs?
Only one PSN is elected as active for the WMI probe in an ISE deployment. The election is based on Bully algorithm so it's somewhat random. The PassiveID report tells which PSN selected.
- How is the load shared to make sure no PSN goes over 100 DCs?
No load sharing for WMI probe at present. For deployments using PassiveID only but not Easy Connect, we could spread the loads using PIC agent.

Hsing,
Can you combine direct WMI probing with DC agents?
Say for example I have 200 DCs to poll:
Would that work? Also how does passive ID work with multiple domains are involved?
