The following table describes the labels in this screen.
25.3 DHCP Relay
Configure DHCP relay on the ONU if the DHCP clients and the DHCP server are not in the
same broadcast domain. During the initial IP address leasing, the ONU helps to relay network
information (such as the IP address and subnet mask) between a DHCP client and a DHCP
server. Once the DHCP client obtains an IP address and can connect to the network, network
information renewal is done between the DHCP client and the DHCP server without the help
of the ONU.
The ONU can be configured as a global DHCP relay. This means that the ONU forwards all
DHCP requests from all domains to the same DHCP server. You can also configure the ONU
to relay DHCP information based on the VLAN membership of the DHCP clients.
25.3.1 DHCP Relay Agent Information
The ONU can add information about the source of client DHCP requests that it relays to a
DHCP server by adding
Relay Agent Information
. This helps provide authentication about
the source of the requests. The DHCP server can then provide an IP address based on this
information. Please refer to RFC 3046 for more details.
The DHCP
Relay Agent Information
feature adds an Agent Information field to the
Option
82
field. The
Option 82
field is in the DHCP headers of client DHCP request frames that the
ONU relays to a DHCP server.
Relay Agent Information
can include the
System Name
of the ONU if you select this option.
You can change the
System Name
in
Basic Settings
>
General Setup
.
