You need to implement DHCP Snooping at Layer 2 for it to really work, and these days I think all major switch vendors support it. Unless you're building a Linux L2 switch I don't see why you would want to implement DHCP Snooping.

You need DHCP snooping for proper ARP reply filtering. It is the cleanest way of determining MAC address<->IP address mappings.
