32.3.1 Global DHCP Relay Configuration Example
The following 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 159
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.
