Reauthentication Request issue

Kamran Mustafayev — Wed, 04 Mar 2026 06:33:08 GMT

Hi Everyone,

ISE 3.2.0.542 patch 2,7

Our WLC is 9800 17.12.6 version

We recently noticed that user connecting to the network and being connected, but then for some unknown reason it send second authentication request to Cisco ISE and we see this log:

1204 Received reauthenticate request
11220 Prepared the reauthenticate request
11100 RADIUS-Client about to send request - ( port = 1700 , type = Cisco CoA )
11104 RADIUS-Client request timeout expired ( [step latency=15012 ms] Step latency=15012 ms)
11213 No response received from Network Access Device after sending a Dynamic Authorization request

Event 5417 Dynamic Authorization failed
Failure Reason 11213 No response received from Network Access Device after sending a Dynamic Authorization request

However user is ok and working fine

Anyone faced such problem? Then only thing we added recently is Posture Reassestment Policy (PRA)

Since you recently added Posture Reassessment (PRA), ISE is now proactively sending CoA requests at defined intervals.Review the PRA interval. If it is too aggressive, it may trigger these errors more frequently during roaming events.

Also check and Ensure that port 1700 is open in both directions between your ISE PSN nodes and the WLC management/redundancy interface.

5417 Dynamic Authorization failed
Applies to: All EAP types and MAB
Possible Causes: NAD is not configured with change of authorization (CoA) from ISE PSN.
Resolution : Check the connectivity between ISE and the NAD. Ensure that ISE is defined as
the dynamic authorization client on NAD and that CoA is supported on device

Failure Reason 11213 - check below post :

Hi, 1700 is open and works fine, PRA set to 1 hour with 5 min default grace, I noticed it happens only in the morning when most of users comes to the office

may be peak hours issue, so need to look different devices any thing stopping due to high load in the network.
