I wouldn't bother with cisco's commercial product. Trying to use that to track real-world flows is like trying to use a kitchen sieve to empty Lake Champlain. A) It seems to barf on datasets > ~1.2GB (the error message was similar to "32478236924") B) Regular java blowups with things like formatNumberException (for big sums) and other java exceptions. This typically causes the app to lose sanity, requiring you to quit and restart it. C) The functionality is weak there's no way to ask for very specific info (e.g. tell me only about AS6172) sorting doesn't put the two halfs of flows together (i.e. you can sort only by either src or dst as) D) stores data in a "different" ASCII format - so the freeware tools aren't usable (at least not that I've found the "real" data so far ...) You're better off with the freeware stuff - if you need/want graphs/charts you can always pipe through sed/perl and into gnuplot...
