Test Cable
Click Test Cable to 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 com-
mand 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.
