Commands
load-balance (E-Series) — balances traffic over E-Series port channel members.
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.
