%AAA-3-SERVER_INTERNAL_ERROR: Switch 1 R0/0: sessmgrd: Server

[pnowikow]

Community members,

As of last night, I'm running ISE 2.3 patch 7 (we upgraded from patch 5) and in most of my switch logs I get this error.  Has anyone seen this?  

%AAA-3-SERVER_INTERNAL_ERROR: Switch 1 R0/0: sessmgrd: Server '(null)': No server stats to increment access accept count!

 - Tough to be the first one, especially with ISE , don't recommend it actually - anyway check if the switch running software version is compatible with this ISE version :

We verified compatibility already. I'm running 16.12.02.

Thanks,

Check the ISE logs for the particular auth request (too). Are there any
errors ?

Hi,

   It could be just a coincidence. Check this thread for the solution:

I ran into this recently. My customer was using radius server-private instead of radius server.  Do you also use server-private?  Try the regular radius server syntax.

We do use server-private and tried to get "radius server" to work but I
couldn't figure out the syntax. Could you provide an example?

Christian,

It took me a little trial and error but I got your instructions to work.  

Thanks a lot!
