Status Displays the cable status. Test results include normal, close, open and crosstalk.
Normal : The cable is normally connected.
Close: A short circuit caused by an abnormal contact of wires in the cable.
Open: No device is connected to the other end or the connectivity is broken.
Crosstalk: Impedance mismatch caused by the poor quality of the cable.
Length If the connection status is normal, here displays the length range of the cable. The
value makes sense only when the cable is longer than 30m.
Error If the connection status is short, close or crosstalk, here displays the length from
the port to the trouble spot. The value makes sense only when the cable is longer
than 30m.
4.2 Using the CLI
On privileged EXEC mode or any other configuration mode, you can use the following
command to check the connection status of the cable that is connected to the switch.
show cable-diagnostics interface { gigabitEthernet
port
|
ten-
gigabitEthernet
port
}
View the cable diagnostics of the connected Ethernet Port.
port
: Enter the port number in 1/0/1 format to check the result of the cable test.
The following example shows how to check the cable diagnostics of port 1/0/2:
Switch#show cable-diagnostics interface gigabitEhternet 1/0/2
Port Pair Status Length Error
Gi1/0/2 Pair-A Normal 2 (+/- 10m) ---
Pair-B Normal 2 (+/- 10m) ---
Pair-C Normal 0 (+/- 10m) ---
Pair-D Normal 2 (+/- 10m) ---
