Cable Diagnostics

Managing Cable Diagnostics

Feature overview

The cable diagnostics feature offers the possibility to locate and characterize faults in ethernet cables by

using time-domain reflectometry. A cable diagnostics test verifies the status of all the four twisted pairs

of an ethernet cable and displays the results for each of them. The status for each pair can be one of the

following: OK, Pair Open, Same Pair Short, Cross Pair Short, Pair Busy, and Test in Progress. The cable

diagnostics test also determines the distance in meters at which the fault occurs. A time stamp is also

attached to each test to know when they were performed.

Note

The cable diagnostics feature can be configured via CLI, Web, and SNMP.

Attention

Cable diagnostics capable switch is supported starting with cnMatrix release 4.0.

A cable diagnostics test will cause a loss of link for several seconds on that interface.

If a cable diagnostics test is started on an interface that has no cable connected then the

status on that interface will become Test in Progress. It will remain with that status until a

cable is connected so the test can run its course. This does not affect the linking capabilities

of that interface.
