6.4.c Implement and troubleshoot netflow

6.4.c [iii] Export [configuration only]

Expired flows are grouped into “NetFlow export” datagrams for export from the NetFlow- enabled device. NetFlow export datagrams can consist of up to 30 flow records for Version 5 or Version 9 flow export. The NetFlow functionality is configured on a per-interface basis. To configure NetFlow export capabilities, you need to specify the IP address and application port number of the Cisco NetFlow or third-party flow collector. The flow collector is a device that provides NetFlow export data filtering and aggregation capabilities.

ip flow-export destination {ip-address | hostname} udp-port

It specifies the IP address, or hostname of the NetFlow collector, and the UDP port the NetFlow collector is listening on.
