    Hey

     

    Some clients when authenticating to Clearpass seems to send a request every second. The requests get accept and sends output. Can anyone explain this behaviour ?

     

    See picture: (all from the same MS Windows client)

    Iv'e seen this in the past with a WLC almost using 100% CPU. I would start by isolating if it's only on one NAD that has this problem or if it's all of them ?

    Then if it's only one NAD, is it all the clients behind it or only a few ?

    Cheers,
