54.4.5 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 392 Global DHCP Relay Network Example
Configure the DHCP Relay screen as shown. Make sure you select a DHCP option 82 profile (default1 in
this example) 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.
