Console#

Cable Diagnostics

test cable-diagnostics

This command performs cable diagnostics on the specified port to diagnose any cable faults
(short, open, etc.) and report the cable length.

Syntax

test cable-diagnostics interface interface

interface

ethernet unit/port

unit - Unit identifier. (Range: 1)

port - Port number. (Range: 1-12)

Command Mode
Privileged Exec

Command Usage

•

Cable diagnostics are performed using Digital Signal Processing (DSP) test methods. DSP
analyses the cable by sending a pulsed signal into the cable, and then examining the reflection
of that pulse.

•

This cable test is only accurate for cables 7 - 140 meters long.

•

The test takes approximately 5 seconds. The switch displays the results of the test immediately
upon completion, including common cable failures, as well as the status and approximate
length of each cable pair.

•

Potential conditions which may be listed by the diagnostics include:

•

OK: Correctly terminated pair

•

Open: Open pair, no link partner
