Status:	Displays the connection status of the cable connected to the port. The
	test results of the cable include normal, close, open or impedance.
Length:	If the connection status is normal, here displays the length range of
	the cable.
Error:	If the connection status is close, open or impedance, here displays the
	error length of the cable.

Note:

1.The Length displayed here is the length of pair cable not that of the physical cable.

2.The test result is just for your reference.

14.3.2 Loopback

Loopback test function, looping the sender and the receiver of the signal, is used to test whether the port of the switch is available as well as to check and analyze the physical connection status of the port to help you locate and solve network malfunctions.
