DescriptionField
The location of the problem on the cable, with respect
to your device. TDR can only find the location in one
of these cases:
•
The cable is properly connected, the link is up,
and the interface speed is 1000 Mb/s.
•
The cable is open.
•
The cable has a short.
Pair length
The name of the pair of wires to which the local pair
is connected. TDR can learn about the remote pair
only when the cable is properly connected and the
link is up.
Remote pair
The status of the pair of wires on which TDR is
running:
• Normal—The pair of wires is properly
connected.
• Not completed—The test is running and is not
completed.
• Not supported—The interface does not support
TDR.
• Open—The pair of wires is open.
• Shorted—The pair of wires is shorted.
• ImpedanceMis—The impedance is mismatched.
• Short/Impedance Mismatched—The impedance
mismatched or the cable is short.
• InProgress—The diagnostic test is in progress.
Pair status
This example shows the output from the show interface interface-id command when TDR is running:
Device# show interface gigabitethernet1/0/2
gigabitethernet1/0/2 is up, line protocol is up (connected: TDR in Progress)
This example shows the output from the show cable-diagnostics tdr interface interface-id command when
TDR is not running:
Device# show cable-diagnostics tdr interface gigabitethernet1/0/2
% TDR test was never issued on gigabitethernet1/0/2
