[c-nsp] Cat 6500 and counters

Hi,

thanks to all that have responded so far.  Seems we'll go the Sup730-3B
road (and not XL, for now).

One question remains, though:

Can someone else confirm this, that "unsampled netflow" will be a 
CPU problem?

For billing, we won't need netflow on most of the ports, but for some
parts of the network, we can't do without (yet), and sampled netflow is
BAD for that (if just because there have been some cases in court recently
where the court said "this is not science, this is just guesswork, it
cannot be accepted as a serious base for billing").
