ip flow-export
This command defines the host/port to send flow statistics to. IP flow (NetFlow) is a feature that gives the ability to collect IP network traffic. The NetFlow records are generated from the firewall statistics. Since the NetFlow information is taken from the firewall, you must activate firewall capabilities on the monitored interface.
