[c-nsp] Netflow Top Talkers?

[Ben Steele]

As much as I hate replying to my own posts I just had to bring it up  
for my own knowledge.

IIRC enabling ip route-cache flow on a subinterface makes it global  
for the entire interface, is that right/still the case? in which case  
I think is the reason I preferred using ip accounting when looking for  
a quick view of an offender on a router.
