ISE 2.4 and error 12953

Hi,

I have ISE 2.4.0.357.

On ISE I configured authentication dot1x for domain PC and MAB for printers and IP Phones. But authentication dot1x doesn't work and in ise logs I see the next error: 

Failure Reason12953 Received EAP packet from the middle of conversation that contains a session on this PSN that does not exist
ResolutionVerify known NAD issues and published bugs. Verify NAD configuration. Turn debug log on DEBUG level to troubleshoot the problem.
Root causeSession was not found on this PSN. Possible unexpected NAD behavior. Session belongs to this PSN according to hostname but may has already been reaped by timeout. This packet arrived too late.

 

Can anybody faced with problem like this?

 

The output command sh run int fa0/23 is:
!
interface FastEthernet0/23
description 204/1
switchport access vlan 101
switchport mode access
authentication event fail action next-method
authentication event server dead action authorize vlan 101

authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
authentication violation restrict

dot1x pae authenticator

end

 

The output command sh run | in rad is:

It appears that you are missing the following, per RADIUS Server Configuration on the Switch

radius-server attribute 25 access-request include

All Releases of IOS Software shows 12.2.55-SE12 recommended for this switch and 15.0.2-SE11 the latest that can run on the switch. Please consider updating the IOS binary.

End-of-Sale and End-of-Life Announcement for the Cisco Catalyst 2960 Series Switches shows this switch series going to end of support later this. So, please plan to replace it.

 

 

No, I don't missing this command, I have this one in RADIUS server configuration. I wrote all attributes:

radius-server attribute 6 on-for-login-auth
radius-server attribute 8 include-in-access-req
radius-server attribute 25 access-request include
