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.
