Hi Cisco ISE expert,
An very strange issue just happened from my client's ISE deployement.
A server with a static IP as 10.42.x.x passed authentication but it's showing a 169.254.x.x IP address from ISE log.
And the server was offline, the user was not able to ping the 10.42.x.x address.
After the admin issued re-authentication, it came back online with the 10.42.x.x
I have attached a screenshot of the log.
Does someone happen to know why this happend?
Thanks.

Can you post your switchport configuration?
My guess is that the server times out on DHCP.
Thank you for rating helpful posts!
