DHCP Snooping
DHCP Snooping is a layer 2 security mechanism incorporated into the switch, preventing rogue DHCP servers from offering unauthorized IP addresses to DHCP clients.
Upon DHCP snooping enabled on a VLAN, the switch will examine DHCP messages sent from untrusted hosts with the VLAN and extracts their IP addresses/lease information to build and maintain the DHCP snooping database. After verification by this database, verified hosts can be granted access to the network.
