Testing the cable connection of an Ethernet interface

IMPORTANT:

If the link of an Ethernet port is up, testing its cable connection will cause the link to go down and then come up.
Fiber ports do not support this feature.

This feature tests the cable connection of an Ethernet interface and displays cable test results within 5 seconds. The test results include the cable's status and some physical parameters. If any fault is detected, the test results include the length of the faulty cable segment.
