Usage
Information
This command provides egress port information for a given IP flow. This information is useful in
identifying which interface the packet follows 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.
The show ip flow command 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.
Example
