Dave, It depends on how you define your aggregates - But, using the default on 7507 RSP2 64 Megs, exporting Flow stats from a table with an average of 10,000 flows doesn't seem to hurt very much. Maybe 5% CPU on the Router. It's the Sun box that takes the hit.

Does anyone have any data points they'd share regarding the impact of netflow export on cpu load? I'd like to capture all of my netflow stats, but I'm worried about scalability. Thanks, davec
