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
