Cable Diagnosis in D-Link Switches

To diagnose the cable in D-Link switches, take the DES-3200 model as an example, just type:

cable_diag ports PORT_NUMBER

For example, perform the diagnostics of ports 1 through 5:

cable_diag ports 1-5

Via the web interface, this function can be found in the “Monitoring” -> “Cable Diagnostic“.

The test can show the distance at which the cable may be damaged.
