Administrator Guide

The output displays three entries:
• Egress port for unfragmented packets.
• In the event of fragmented packets, the egress port of the first fragment.
• In the event of fragmented packets, the egress port of the subsequent fragments.
NOTE: In the show port channel flow command output, the egress port for an unknown
unicast, multicast, or broadcast traffic is not displayed.
The following example shows the show port-channel-flow outgoing-port-channel number
incoming-interface interface source-mac address destination-mac address
• Load-balance is configured for MAC
• Load-balance is configured for IP 4-tuple/2-tuple
• A non-IP payload is going out of Layer 2 LAG interface that is a member of VLAN with an IP address
Example
DellEMC# show port-channel-flow outgoing-port-channel 1 incoming-interface
gi 3/3
source-mac 00:00:50:00:00:00 destination-mac 00:00:a0:00:00:00
Egress Port for port-channel 1, for the given flow, is Gi 13/2
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.
