Cable Test Command

The cable test feature enables you to determine the cable connection status on a selected 
port. 

The cable test feature is supported only for copper cable. It is not 

supported for optical fiber cable. If the port has an active link while 
the cable test is run, the link can go down for the duration of the test.

This command returns the status of the specified port.

sFlow Commands

sFlow

®

 is the standard for monitoring high-speed switched and routed networks. sFlow 

technology is built into network equipment and gives complete visibility into network activity, 
enabling effective management and control of network resources. 

Privileged EXEC

One of the following statuses is returned:

•  Normal: The cable is working correctly.

•  Open: The cable is disconnected 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 working.

If this feature is supported by the PHY for the current link speed, the cable length is 
displayed as a range between 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.
