With Time Domain Reflectometer (TDR) cable diagnostic, you can test Ethernet cables connected to a switch port or ports for defects. The cable diagnostic detects the state of the port or ports, the status of the cable pairs, and the length of the cable.
Note
You can perform TDR cable diagnostic on copper ports.
The following table lists the states of the cables connected to a port or ports.

|
Open/Short |
Detects either a short circuit on the cable or a lack of continuity between the pins at each end of the cable. |
