The 802.1X screen displays a filtered capture of packets detected by the

LanExpert. Select START to start the test and watch the actual frame

detected from the LanExpert. Select STOP to stop the capture.

The LanExpert detects and saves the last received 64 802.1X

frames received. If configured in INDEP mode only 802.1X traffic on port

the frame was detected.

5th line - the 802.1X frame type number and the text description

of the type (e.g. EAP, Start, Logoff etc.)

6th line - the 802.1X frame payload byte length (if the type is

known to require a payload and there is not one then ERROR is

also displayed).

The following only is shown for 802.1X frame type EAP with a valid

payload size –

(e.g. Request, Response, Success, Failure)
