hub

In the network we have a few vlans but at the moment I was investigating vlan2 which carries the most traffic. When tcpdumping on the eth0.2 interface, I see a lot of packets arriving which are not addressed to, nor coming from the server. I checked this on several servers in the network and they all have the same issues.

In short, our switches don't switch the traffic but threat it like they are a hub. Can you tell me what settings on the dell poweredge 6248 should prevent this behaviour?
