19: <p>NetFlow is a protocol for exporting aggregated traffic information
20: with UDP packets flow. NetFlow is generated by <code>ng_netflow(4)</code> node.
21: To enable NetFlow on a particular interface <code>netflow-in</code> or
22: <code>netflow-out</code> options should be used. Best practice is to enable
23: netflow on every interface in system in only one direction:
24: incoming for "ingress" flow or outgoing for "egress" flow.</p>
25: <p><b>Note:</b> Netflow configuration is global for the daemon,
26: so it must be done before first bundle get connected.</p>
27: <p><b>Note:</b> This feature is available only on FreeBSD 6.0-RELEASE
28: and newer. NetFlow v9 supprted only on FreeBSD 9.0-RELEASE and newer.</p>
