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 (configuredrefer 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.
tdr-cable-test
