DIAGNOSTICS TDR INTERFACE
test cable-diagnostics tdr interface
Overview Use this command to apply the Cable Fault Locator’s cable-diagnostics tests to
twisted pair data cables for a selected port. The tests will detect either correct,
short circuit, or open, circuit terminations. For more information on running the
CFL, see the
“Cable Fault Locator” Feature Overview and Configuration Guide .
The test can take several seconds to complete. See the related show command to
display the test results.
A new test can only be started if no other test is in progress. CFL cannot run on a
port that is currently supplying power via PoE.
The displayed status of the cable can be either, OK, Short (within-pair), or Open.
The “Open” or “Short” status is accompanied with the distance from the source
port to the incorrect termination.
