Usage Information
Because this command calculates based on a Layer 2 hash algorithm, use this command to display flows 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 identification in a given port-channel if a
valid flow is entered. A mismatched flow error occurs if MAC-based hashing is configured for a Layer 2 interface
and you are trying to display a Layer 3 flow.
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.
