36.4.3 Global DHCP Relay Configuration Example
The follow figure shows a network example where the Switch is used to relay
DHCP requests for the VLAN1 and VLAN2 domains. There is only one DHCP
server that services the DHCP clients in both domains.
Figure 174 Global DHCP Relay Network Example
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.
