DHCP Snooping
DHCP snooping is a security feature that monitors DHCP messages between a DHCP client
and DHCP server to filter harmful DHCP message and to build a bindings database of (MAC
address, IP address, VLAN ID, port) tuples that are considered authorized. The network
administrator enables DHCP snooping globally and on specific VLANs and configures ports
within the VLAN to be trusted or untrusted. DHCP servers must be reached through trusted
ports.
