Dear Community,
We use ISE 3.1
1. Primary Admin Node - DC Secondary site
2. Secondary Node and pxGRID Node - DC Primary site We are planning to perform test ISE functionality to ensure current Node can handle all sessions by disconnect for 1 of DC links.
It mean PAN and Secondary Node no connectivity to each other, assume Secondary Node no connectivity to PAN / down around 3 hours.
Q1: What is the issue if active-active PSN lost connection withing 3 hours, then connection comes back? please share us the best practice.
Q2: Should we de-register both active-active PSN to standalone then connection right back to register?
ISE integrate with AD. Do we have to validate on DNS / IP?
Best Regards,
