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:
Message 1 %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
(E-Series)
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
