Time Domain Reflectometer (TDR) Commands
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 100/1000/10G Base-T
modules.
• tdr-cable-test
• show tdr
Important Points to Remember
• The interface and port must be enabled (configured—see 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.
