Howdy,
Does anyone know of any good IP monitoring tools that can log/monitor

the

TYPES of IP traffic going across your netowork (ie: one that logs

tcp/udp and

esp port numbers/types of traffic)? Something that could query a

router

would be nice, although I am unaware of any routers that support such a

feature.

Even something that you could put on a box on the same ethernet subnet

would

do the job. I'm curious as to the types of traffic our customers are

pushing

as I am attempting to better analyze our usage.

If you're using Cisco routers you can turn on Netflow switching. For
