CoA issues between ISE and 3750x

We are having an issue using the cisco ise 1.1.2 and a 3750x (Version 12.2(58)SE2)

When the radius sends a reauthentication CoA message to the switch, the switch responds with a 'session contect not found' reply. I have upgraded the code to the latest levels on both the ise and switch and still have the same resultts.

This reauthenticate is needed after the NAC profiler determines the pc is complient. I am receiving the complient message from the pc and switch, but becuase the switch never reauthentices the client after the CoA request, the client is never granted full access.

I am not sure if the radius server is sending the wrong session id, or if the switch is looking at it wrong.

Please Help...!!!!!

CoA issues between ISE and 3750x

What version of code are you running on both ISE and the NAD?

Beginner

CoA issues between ISE and 3750x

cisco ise 1.1.2 and a 3750x (Version 12.2(58)SE2)

We have the fix for this...

We had to downgrade to 12.2.(55)se7 on the 3750 and allow radius attribute 25 on the switch config.

..

radius-server attribute 25 access-request include

..

CoA is now functioning properly...

I was suspecting that the version of code could be the problem Also, you can always use ISE's "Evaluate ConfigurationValidator" which can be found under "Operations > Diagnostic Tools." It is not 100% cross platform accurate but it definitely helps catching small things that you missed.

In either case, good job on finding the solution and posting back here! (+5 from me).

If your issue is resolved please mark the thread as "answered"

Upgrade the IOS on the Catalyst 3750, we were having the same problem here and it was solved by upgrading to

Version 15.0(2)SE2.

Hope that helps.

As per the cisco recommendation IOSv12.2(52)SE is suitable for Catalyst 3750-X which will support all  the features without any issues like  MAB,802.1X,CWA,LWA,COA,VLAN,DACL,SAG as mentioned in the link below:

http://www.cisco.com/en/US/docs/security/ise/1.1.1/compatibility/ise_sdt.html.

I see you are using IOSv12.2(58)SE2,which is not recommended.So you can  downgrade to IOSv12.2(52)SE which will solve your issues.
