Somewhat related to this thread,

Is there some sort of 'magic' you have to do with a Sup720 to get it to
export flows egress and ingress?

It appears that there is quite a bit of traffic "missing" from the NetFlow
data (most of it infact)...

I simply applied ip route-cache flow to the layer3 vlans of interest and
then setup the export commands as documented.

Are there other steps required?

Thanks,
-Drew
