Thanks for the suggestion - Our routers are doing "one armed routing", so

I didn't catch what platform you're using, michael, but you probably
want is...
int Po1.xxx
encap dot1q xxx
ip flow ingress
If your platform supports it. That enables collection _just_ on the
subinterface (it is a relatively new feature). Remove "ip route-cache
flow" from the parent, and enable "ip flow ingress" on just the
subinterfaces you're interested in.
That should give you working subinterface ifindexes in the Netflow PDUs.
Works fine for us on C7206/C7304-NPEG100, running 12.2(18)S and 12.0(26)S.
