Time Domain Reflectometer (TDR)
TDR is useful for troubleshooting an interface that is not establishing a link; either it is flapping or not
coming up at all. TDR detects open or short conditions of copper cables on 100/1000 Base-T modules.
Important Points to Remember
• The interface and port must be enabled (configured — refer to the
interface
command) before
running TDR. An error message is generated if you have not enabled the interface.
• The interface on the far-end device must be shut down before running TDR.
• Because TDR is an intrusive test on an interface that is not establishing a link, do not run TDR on an
interface that is passing traffic.
• When testing between two devices, do not run the test on both ends of the cable.
