Syntax
test cable-diagnostics [PORT-LIST]
Description
Use the command to test the cable faults.
Option
Specify only copper port as a input port number.
Example output
Example of an usage of invalid(fiber-SFP+) port:
switch# test cable-diagnostics 1/a1
The transceiver on port 1/A1 does not support cable diagnostics.
Example of ports being specified from 1/1 to 1/48, which are valid copper 1G ports. The selected range includes an entry for an invalid port, hence the output has a entry for non-supported port and does not display any output for valid ports.
switch# test cable-diagnostics 1/1-1/a1
The transceiver on port 1/A1 does not support cable diagnostics.
Example of valid ports being specified:
switch# test cable-diagnostics 1/1-1/10
This command will cause a loss of link on all tested ports and will take
several seconds per port to complete. Use the ‘show cable-diagnostics’ command to view the results.
Continue (y/n)? y
switch# show cable-diagnostics 1/1-1/10
