Field Description
Cable Status One of the following statuses is returned:
• Normal: The c
able is w
orking correctly.
• Open: The cable is disc
onnected or there is a faulty connector.
• Short: There is an electrical short in the cable.
• Cable Test Failed: The cable status could not be determined. The cable may in fact be
w
orking.
Cable Length If this feature is supported by the PHY for the current link speed, the cable length is displayed
as a range be
tween the shortest estimated length and the longest estimated length. Note
that if the link is down and a cable is attached to a 10/100 Ethernet adapter, then the cable
status may display as Open or Short because some Ethernet adapters leave unused wire pairs
unterminated or grounded. Unknown is displayed if the cable length could not be
determined.
