Figure 241 DHCP Smart Relay Network Example
Configure the NETWORKING > DHCP > DHCPv4 Relay > DHCP Smart 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. Click Apply after you finish
the configuration.
