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.
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
Dell# 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
