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.
