Command Buttons
Test Cable - Perform a cable test on the selected interface. The cable test may take up to 2 seconds
to complete. If the port has an active link then the link is not taken down and the cable status is
always "Normal". The command returns a cable length estimate if this feature is supported by the
PHY for the current link speed. Note that if the link is down and a cable is attached to a 10/100
Ethernet adapter then the cable status may be "Open" or "Short" because some Ethernet adapters
leave unused wire pairs unterminated or grounded.
