Egress Port for port-channel 1, for the given flow, is Te 13/2
Time Domain Reectometer (TDR)
TDR is useful for troubleshooting an interface that is not establishing a link; either it is apping 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 (congured—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
trac.
• When testing between two devices, do not run the test on both ends of the cable.
