Please note that this thread was explicitely talking about 6500/7600
hardware...

Don't use "ip route-cache flow" (which is a "early stone age" command, 
and can only be set on the main interface, and automatically enables 
flow accounting for all sub-interfaces).  

Use "ip flow ingress", which is per-subif.
