33.4.3 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 147 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.
