• To test a single interface, select the check box associated with the port, or type the
port number in the Go To Interface
field and click the Go button.
• To test multiple interfaces, select the check box associated with each interface.

the
cables.
9. Click the Apply

A cable test is performed on all selected ports. The cable test might take up to two
seconds to complete. If the port forms an active link with a device, the cable status is
always Normal. The
test 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 might be Open or Short because some
Ethernet adapters leave unused wire pairs unterminated or grounded.
The following table describes the nonconfigurable information displayed on the page.
