Hi dears,
I deployed the ISE primary and secondary mode. Then I did deregister the secondary ISE at Primary ISE. Now i want to register the same second ISE as secondary mode on Primary ISE. but this error occur:
Unable to register SecondaryISE. Node is not a Standalone node.
I connect the secondary ISE and see deployement personas
Administration: Secondary
Monitoring: Secondary
Then I did promote to primary command after that ISE is log out but the problem is not solve.
version 1.20.8xx of both ISE's
How i solve this issue?
Thanks
