Cacti will work for port based monitoring, it won't work
for flow-based monitoring though.

ntop would probably be the main "free" flow based monitor,
though there are some really really nice commercial
products.

Inmon has a couple free tools as well sflowtrend, and another
command line tool which can dump the contents of sflow data
to STDOUT for parsing by a script.
