Version Description
9.3.0.0 Introduced on the Z9000.
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 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.
