ISE 1.2 Patch 2 External RADIUS Server Sequence Broken?

Ashley Georgeson — Mon, 11 Mar 2019 03:59:30 GMT

Hi community,

We have upgraded our proof of concept ISE 1.2 lab to Patch level 2.

Our lab design includes the use of external RADIUS servers which we off-load certain authentication rules to.

To ensure resiliency of the external RADIUS service, we have two of these which we add to a RADIUS Server Sequence, the idea being that if the first in the list is unavailable, ISE will try the second and all will be well.

Now this worked for us in testing ISE 1.2, but I have noticed that after the upgrade to Patch 2 ISE is sending the majority RADIUS traffic to the first (failed) external RADIUS server, with only the odd RADIUS Access-Request to thte next in the list.

Anybody else come across this??

Many thanks, Ash.

I couldn't find any known issues with this feature. Could you please paste the screen shot of external radius sequence and configuration. Also, how are we determing that the first server in the sequence is DEAD?
