Configure the DHCP Relay screen as shown. Make sure you select the Option 82 check box
to set the switch to send additional information (such as the VLAN ID) together with the
DHCP requests to the DHCP server. This allows the DHCP server to assign the appropriate IP
address according to the VLAN ID.
