DESCRIPTION
Select this check box to enable DHCP relay.
Enter the IP address of a DHCP server in dotted decimal notation.
Select the Option 82 check box to have the ONU add information (slot number, port
number and VLAN ID) to client DHCP requests that it relays to a DHCP server.
This read-only field displays the system name you configure in the General Setup
screen.
Select the check box for the ONU to add the system name to the client DHCP

Click Apply to save your changes to the ONU's run-time memory. The ONU loses
these changes if it is turned off or loses power, so use the Save link on the top
