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
DellEMC# show ip flow interface te 2/42 20.1.1.1 100.1.1.2 protocol tcp
Flow: 20.1.1.1 100.1.1.2 6
Ingress interface: Te 2/42
Egress Interface: Te 2/43
