Usage
Information
Since 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 the user is trying to display a Layer 3 flow.
The output will display three entries:
• Egress port for unfragmented packets.
• In the event of fragmented packets, egress port of the first fragment.
• In the event of fragmented packets, egress port of the subsequent fragments.
Example
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 for the C-Series and S-Series
incoming-interface
interface
Enter the keyword incoming-interface followed by the interface type and slot/
port or number information:
• For a Fast Ethernet interface, enter the keyword
FastEthernet followed by the
slot/port information.
• For a 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet
followed by the slot/port information.
• For a SONET interface, enter the keyword sonet followed by the slot/port
information.
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet
followed by the slot/port information.
source-ip address Enter the keyword source-ip followed by the IP source address in IP address
format.
destination-ip address Enter the keyword destination-ip followed by the IP destination address in IP
address format.

Note: The protocol number keyword applies to E-Series only.
source-port number Enter the keyword source-port followed by the source port number.
Range: 1-65536
Default: None
destination-port
number
Enter the keyword destination-port followed by the destination port number.
Range: 1-65536

source-mac address Enter the keyword source-mac followed by the MAC source address in the
nn:nn:nn:nn:nn:nn format.
destination-mac
address
Enter the keyword destination-mac followed by the MAC destination address in
the nn:nn:nn:nn:nn:nn format.
