IPv6 DHCP Snooping

4.4.3.1 Base

Global

Use the IPv6 DHCP Snooping Configuration page to view and configure the global
settings for IPv6 DHCP snooping. IPv6 DHCP snooping is a security feature that
monitors DHCPv6 messages between a DHCPv6 client and DHCPv6 servers to filter
harmful DHCPv6 messages and to build a bindings database of {MAC address, IPv6
address, VLAN ID, port} tuples that are considered authorized. You can enable IPv6
DHCP snooping globally and on specific VLANs, and configure ports within the VLAN
to be trusted or untrusted. If a DHCPv6 message arrives on an untrusted port, IPv6
DHCP snooping filters messages that are not from authorized DHCPv6 clients.
DHCPv6 server messages are forwarded only through trusted ports.
