Interface Commands

Short: Shorted pair

Not Supported: This message is displayed for any Fast Ethernet ports that are linked up, or
for any Gigabit Ethernet ports linked up at a speed lower than 1000 Mbps.

Impedance mismatch: Terminating impedance is not in the reference range.

Ports are linked down while running cable diagnostics.

To ensure more accurate measurement of the length to a fault, first disable power-saving
mode (using the

no power-save

command) on the link partner before running cable

diagnostics.

Privileged Exec

Command Usage

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.
