DHCP snooping is able to validate DHCP messages obtained from untrusted sources and filter
out invalid message.
For DHCP snooping to function properly, it is suggested to connect DHCP servers to
VigorSwitch through trusted interfaces; because untrusted DHCP messages will be forwarded
to trusted interfaces only.
