Cable diagnostics are performed using Time Domain Reflectometry

(TDR) test methods. TDR 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 Gigabit Ethernet cables 0 - 250

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 to a fault.

Potential conditions which may be listed by the diagnostics include:

OK: Correctly terminated pair

Open: Open pair, no link partner

Short: Shorted pair

Not Supported: This message is displayed for any Fast Ethernet

ports, or Gigabit Ethernet ports linked up at a speed lower than

Impedance mismatch: Terminating impedance is not in the

reference range.

Ports are linked down while running cable diagnostics.

These parameters are displayed:

Port – Port identifier.

Type – Displays media type. (FE – Fast Ethernet, GE – Gigabit

Ethernet, Other – SFP)

Link Status – Shows if the port link is up or down.

Test Result – The results include common cable failures, as well as the

status and approximate distance to a fault, or the approximate cable

length if no fault is found.

To ensure more accurate measurement of the length to a fault, first

disable power-saving mode on the link partner before running cable

diagnostics.

For link-down ports, the reported distance to a fault is accurate to

within +/- 2 meters. For link-up ports, the accuracy is +/- 10 meters.

Last Updated – Shows the last time this port was tested.
