DHCP snooping acts as a guardian of network security by keeping track of valid IP addresses assigned to downstream network devices by a trusted DHCP server (the server is connected to a trusted network port). By default, all trunk ports on the switch are trusted and all access ports are untrusted for DHCP snooping. The purpose of having DHCP relay agent is to permit DHCP clients and servers be placed on numerous networks. It is not difficult to set up DHCP in a definite network segment. Messages in the DHCP network are IP broadcast and this means that all computers on the sector can respond. All it takes is a single scope on a single DHCP server.
