    Hi,

    I have met a problem. Some client is randomly TIMEOUT with code ERRORS 9002. ( 7 client/100 client)

    I implemented authenticated with basic mode (non TLS). Can anyone suggest how to fix this.

    Hi ,

     

    It looks you are doing EAP-PEAP authentication by using AD as authentication source. In log what I see after user found in AD, CPPM server as sent EAP request MSCHPv2 Access challange identity to supplicant at 13:41:15 through NAD devcies (controller/switch) but it diidnt recevied any response and waited for 47 seconds and request get deleted.

     

    We need to look in to NAD device first whether it forwared server challange to supplicant or not, if it forward but client is not respoding then need to debug issue on cleint side.

    Check for display radius statistics and port debugging, it will give idea.

    can you check machine certificate installed on the Client machine?

    Hi,

    I didn't check: "Verify the server's identity by validating the certificate" for all the computer.

    I make this simply by bypassing it.

    Kind Regards,
