[nsp] Suggestions on tracking down bandwidth offenders

[Michael Axelrod]

I use netflow for a quick look at the top traffic consumers.
Statistics can be cleared  - "clear ip flow stats" - and you can view the
stats flow by flow.
Just need to make sure that netflow is on the egress and ingress interfaces
to get bi-directional traffic stats.
