Console#
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
• 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.
