Commands

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.

Defaults none
Command Modes EXEC
• Load-balance is configured for IP 5-tuple/3-tuple
• An IP payload is going out of a Layer 2 LAG interface that is a member of a VLAN with
an IP address
– balances traffic over E-Series port channel members.
