Select the check box next to each port on which to run the cable test. 3. Click the Apply button. The cable test is run on all selected ports. The cable test can 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 can be Open or Short because some Ethernet adapters leave unused wire pairs unterminated or grounded.
