HI, Gianluigi

You do not need to configure the switch as a relay agent working on Layer 3 mode which will lead to that server recevices two dhcp message, one from switch the other from client broadcasting. You can only open the function of adding option 82 on switch and the switch works on layer 2 mode. As I know most of layer 2 switches can support this feature and some of them maybe need to open "dhcp snooping" at the same time. Then the switch only adds option 82 which include what you need and there is only one meesage under processing.
