Cable Diagnostics
Cable Diagnostics helps you to detect whether your cable
has connectivity problems provides information about
where errors have occurred in the cable. The tests use Time
Domain Reflectometry (TDR) technology to test the quality
of a copper cable attached to a port. TDR detects a cable
fault by sending a signal through the cable and reading
the signal that is reflected back. All or part of the signal is
reflected back either by cable defects or by the end of the
cable when an issue is present. Cables are tested when the
ports are in the down state, with the exception of the cable
length test.

connected. Pair (A, B, C, and D): Displays
