EndPoint abandoning EAP session

[hennie001]

Please clarify and provide resolution:

Event	5440 Endpoint abandoned EAP session and started new
Failure Reason	5440 Endpoint abandoned EAP session and started new
Resolution	Verify known NAD or supplicant issues and published bugs. Verify NAD and supplicant configuration.
Root cause	Endpoint started new authentication while previous is still in progress. Most probable that supplicant on that endpoint stopped conducting the previous authentication and started the new one. Closing the previous authentication

Hi Hennie,

You need to provide some more info on this.

What is the deployment like ?

What is the ISE version, which clients are you using ?

Regards,

Aditya

Cisco ISE version 1.3.

Native Windows 802.1x supplicant.

The problem is intermittent - same PC authenticates mostly - only fails sometimes.

Cheers, Hennie

Hi Aditya, Our network is all Cisco (3750, 3850, 4500, 2960).

We use ISE version 1.3 and the user devices are mostly Windows (7, 8, 8.1, 10)

It seems to happen mostly on Win 7...

We use native Windows 802.1x on the user devices.

Thanks, HennieG
