Version 8.3.10.0 Introduced on the S4810.
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.

channel number incoming-interface interface source-mac address
