There is open question to expected sequence of events for DNAC-ISE integration in the following scenario:
1) DNAC cluster (optionally multiple DNAC deployment e.g. Author&Readers) integrated with large distributed ISE-cube with ERS (DNAC-2-xPAN nodes) & pxGrid (DNAC-2-xPxGrid nodes). Connections are established for both functions & work w/o issues. ISE-cube configured w/o automatic PAN switchover.
2) due to the maintenance need primary PAN & one of PxGrid nodes are taken offline.
Question: are both integrations (especially ERS one - DNAC-2-secondaryPAN) kept fully operational? My thought is live connections (to secondary PAN & 2nd PxGrid) wont signal any alarms although ERS integration wont be functional until secondary PAN gets manually promoted primary role & converges as one.
can anybody assist here?
