30.4.3 DHCP Relay Configuration Example

The follow figure shows a network example where the switch is used to relay DHCP requests
for the RD and Sales network. There is only one DHCP server that services the DHCP clients
in both networks.

Figure 105 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.

DESCRIPTION
Click Apply to save your changes to the switch's run-time memory. The switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Click Cancel to discard all changes and start configuring the screen again.
