Does the switch do NetFlow? That's what you want to do the protocol/app level inspection. I'm guessing no give it's a cheapo Dell switch.
Your next option is mirroring the ports all to one (assuming the switch lets you do that and you don't overrun the buffer on the target machine) and running some sort of traffic analysis/netflow type app on a machine. I don't know of one offhand but this is typically done at the router level but doesn't look like you have the equipment to do that I'd guess.

I am in the middle of deploying MRTG bundle but it's just showing me bandwidth per port on the switch at this time, just to let you know. Thanks for the recommendations...
