Layer 3 Ethernet Interface And Subinterface Configuration Commands; Mac-Address - HP MSR series Command Reference Manual

If the cable connection is normal, the displayed cable length is the total length of the cable.
If the cable connection has a fault, the displayed cable length is the length from the local port to the faulty
point.
Fiber ports do not support this command.
If the link of an Ethernet interface is up, testing its cable connection will cause the link to go down and
then up.
The test result is for reference only. The cable length detection error is up to 5 m (about 16 ft). If a test item
is not available, a hyphen (-) is displayed.
Examples
