36.3.3 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 161 Global DHCP Relay Network Example
DHCP Server:
192.168.1.100
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.
