show port-channel-flow

Display an egress port in a given port-channel flow.

Syntax
show port-channel-flow outgoing-port-channel number incoming-interface interface {source-ip address destination-ip address} | {source-port number destination-port number} | {source-mac address destination-mac address {vlan vlanid | ether-type}}
Parameters
outgoing-port-channel number
Enter the keywords outgoing-port-channel then the number of the port channel to display flow information.
  • For a Port Channel interface, enter the keywords port-channel then a number. The range is from 1 to 128.
incoming-interface interface
Enter the keywords incoming-interface then the interface type and the interface information:
  • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.
  • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
source-ip address
Enter the keywords source-ip then the IP source address in IP address format.
destination-ip address
Enter the keywords destination-ip then the IP destination address in IP address format.
source-port number
Enter the keywords source-port then the source port number. The range is from 1 to 65536. The default is None.
destination-port number
Enter the keywords destination-port then the destination port number. The range is from 1 to 65536. The default is None.
source-mac address
Enter the keywords source-mac then the MAC source address in the nn:nn:nn:nn:nn:nn format.
destination-mac address
Enter the keywords destination-mac then the MAC destination address in the nn:nn:nn:nn:nn:nn format.
vlan vlan-id
Enter the keywords vlan then the VLAN-id. The range is from 0 to 4094.
ether-type
Enter the keywords ether-type in the XX:XX format.

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 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
