40.4.3 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 191 Global DHCP Relay Network Example
DHCP Server: 192.168.1.100
VLAN1VLAN2
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.
