[j-nsp] NetFlow on M7i

[Erdem Sener]

In case you're monitoring on a interface basis, and just the in/out
octets, I would aggree that SNMP is the way to go and using sampling
would just be complexing things unnecessarily.

 However, if you not only need the interface counters but want to have
information on flows (e.g traffic from/to a single host host on a /24
ethernet interface), sampling would do the trick.

Cheers,
Erdem
