As soon as we enable "net flow-export destination 10.1.1.1 2055" on a C6509/Sup720 the traffic seems to be sent out on all of our trunk interfaces. 10.1.1.0/24 is our management network which is trunked out on all trunk interfaces. The Netflow server (10.1.1.1) seems to be collecting the data correctly so why I'm I seeing unicast packets from our 6509 on all trunk interfaces? I was expecting to see Netflow traffic only on the trunk interface where the actual Netflow server is placed.
