traffic monitoring

I am looking to see how much traffic is being sent from a given vlan to a specific server.  Tools like solarwind are not able to provide graphs for something as specific as this.  Has anyone done this?

You could *possibly* do this with Netflow, if your device supports this feature, but with anything else it'd be difficult to track traffic from a given *vlan* to a given port.

You can use Cacti to graph the individual ports, but you can't graph the layer 2 traffic on a VLAN - you can graph an associated SVI if you have one, but that would show you *all* traffic on the VLAN.

Maybe Netflow from the SVI to the server, but I don't know how accurate it would be.

Cheers.

Does the 3750 support netflow?

If so (hopefully), how is it configured?
