IPv4 Routing | 689
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.
