To get the info your looking for, you will need to enable mls flows as well as netflow.

snippet from working 6509:

mls rp nde-address x.x.x.x

mls flow ip full

mls nde sender version 5

ip flow-export source Loopback1

ip flow-export version 5 peer-as

ip flow-export destination x.x.x.x %udp port%

ip flow-aggregation cache as

export destination x.x.x.x %udp port%


You also have to enable " ip route-cache flow" for each interface that you want stats from.
