Directly to the legitimate trusted DHCP Server.
o
A network device relaying DHCP messages to and from a trusted
server.
o
Another trusted source such as a switch with DHCP Snooping enabled.
o
Untrusted ports are connected to DHCP clients and to traffic that
originates outside of the local area network.

The VLANs to which the DHCP Snooping feature applies must be specified in
the DHCP Snooping VLAN Setting configuration.
