Usage
Information
This command provides egress port information for a given IP flow. This is useful in identifying which
interface the packet will follow in the case of Port-channel and Equal Cost Multi Paths. Use this
command for routed packed only. For switched packets use the show port-channel-flow command
show ip flow does not compute the egress port information when load-balance mac hashing is also
configured due to insufficient information (the egress MAC is not available).
S-Series produces the following error message:
%Error: Unable to read IP route table
C-Series produces the message:
%Error: FIB cannot compute the egress port with the current trunk hash setting.
Example FTOS#show ip flow interface Gi 1/8 189.1.1.1 63.0.0.1 protocol tcp
source-port 7898 destination-port 8976
flow: 189.1.1.1 63.0.0.1 protocol 6 7868 8976
Ingress interface: Gi 1/20
Egress interface: Gi 1/14 to 1.7.1.2[CAM hit 103710] unfragmented packet
Gi 1/10 to 1.2.1.2[CAM hit 103710] fragmented packet

vlan followed by a number from 1 to 4094.
brief (OPTIONAL) Enter the keyword brief to view a brief summary of the interfaces and
whether an IP address is assigned.
