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
DellEMC# show port-channel-flow outgoing-port-channel 1 incoming-
interface gi 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 Gi 13/2
