Usage Information
Because this command calculates based on a Layer 2 hash algorithm, use this command to display ows for
switched Layer 2 packets, not for routed packets (use the show ip flow command to display routed packets).
The show port-channel-flow command returns the egress port identication in a given port-channel if a
valid ow is entered. A mismatched ow error occurs if MAC-based hashing is congured for a Layer 2 interface
and you are trying to display a Layer 3 ow.
The output displays three entries:
• Egress port for unfragmented packets.
• In the event of fragmented packets, the egress port of the rst 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 trac 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 congured for MAC
• Load-balance is congured 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 te
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 Te 13/2
Time Domain Reectometer (TDR) Commands
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.
