It means that traffic flow will count only traffic that reaches one of those chains. For example, you set up a mirror port on a switch, connect the mirror port to a router and set traffic flow to count mirrored packets. Routers and switches that support NetFlow can collect IP traffic statistics on all interfaces where NetFlow is enabled, and later export those statistics as NetFlow records toward at least one NetFlow collector—typically a server that does the actual traffic analysis.
