27.3.3 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 125 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.
