A transport portion test packet can be transmitted over a transport portion of the transport segment. Transport portion results can be received in response to the transport portion test packet. The packet portion results and the transport portion results can be correlated to generate correlated test results. The correlated test results can be processed to determine the property of, or isolate the fault in, the transport segment.
