Version 8.3.11.1 Introduced on the Z9000.
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.
The Example below 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 for the C-Series and S-Series
• A non-IP payload is going out of Layer 2 LAG interface that is a member of VLAN with
an IP address
Example
FTOS#show port-channel-flow outgoing-port-channel 1 incoming-
interface gi 3/0
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
13/01
User Information
On the E-Series only:
show port-channel-flow outgoing-port-channel number incoming-
interface interface source-ip address destination-ip address
{protocol number [icmp/tcp/udp]} {source-port number
destination-port number}
• Load-balance is configured for IP 5-tuple/3-tuple
