This is an example of output from the show interface interface-id command when TDR is running:
Switch# show interface fastethernet0/1
fastethernet0/1 is up, line protocol is up (connected: TDR in Progress)
This is an example of output from the show cable-diagnostics tdr interface interface-id command when
TDR is not running:
Switch# show cable-diagnostics tdr interface fastethernet0/1
% TDR test was never issued on fa0/1
If an interface does not support TDR, this message appears:
% TDR test is not supported on switch 1
