Parameter

Description

Bridge Type

It can be set to IP or PPPoE.

Binding options

Used to bind the WAN interface to the

LAN port or to the wireless SSID.

NOTE

Before setting the binding options, set the work

mode of the LAN port or the wireless SSID. The

binding options can be set only after the work

mode or wireless SSID is successfully set. For

details, see

LAN Port Work Mode

and

WLAN Configuration

.

NOTE

l

WAN in route mode: The ONT functions as a gateway. The IP address of the ONT can be obtained

through DHCP, Static, or PPPoE. The IP address of the PC connected to the ONT can be obtained from

the DHCP address pool of the ONT or can be set manually.

l

WAN in bridge mode: The ONT functions as a relay and does not process data. The ONT does not

obtain the IP address allocated by the upper-layer device and it does not allow manual configuration

of a static IP address. The IP address of the device connected to the ONT can be obtained through

DHCP, PPPoE, or static.

l

In the case of the DHCP mode, you need to set the DHCP relay. After configuration is complete,

the user-side IP address is obtained from the upper-layer device. For the detailed procedure, see

DHCP Server Configuration

.

l

In the case of the PPPoE mode, the user-side IP address is obtained through PPPoE authentication

of the upper-layer device.

3.3.3 LAN

This topic describes how to set the working mode of the LAN port, the LAN host, and the DHCP

server through the Web page.

LAN Port Work Mode

1.

Click the

LAN

tab and then choose

LAN Port Work Mode

from the navigation tree. In

the pane on the right, determine whether the LAN port works in layer 3 mode, as shown in

Figure 3-13

.

NOTE

If the check box corresponding to the LAN port is selected, it indicates that the LAN port works in

layer 3 mode, that is, the gateway mode; if the check box corresponding to the LAN port is deselected,

it indicates that the LAN port works in layer 2 mode, that is, the bridge mode.

By default, the check boxes corresponding to all LAN ports are deselected, that is, all LAN ports

work in layer 2 mode.

.

LAN Host Configuration

1.

Click the

LAN

tab and then choose

LAN Host Configuration

from the navigation tree. In

the pane on the right, set the management IP address and subnet mask of the LAN host, as

shown in

Figure 3-14

.

Figure 3-14

LAN Host Configuration

NOTE

The IP address of the device connected to the LAN port must be in the same subnet as the management

IP address. In this way, you can access an ONT through the Web page and perform query and

management. You can manually set the IP address of the device connected to the LAN port to be on

the same network segment as the management IP address, or start the DHCP server to set the IP

address in the DHCP address pool to be on the same network segment as the management IP address.

For details, see

DHCP Server Configuration

DHCP Server Configuration

1.

Click the

LAN

tab and then choose

DHCP Server Configuration

from the navigation tree.

In the pane on the right, you can configure the LAN side DHCP address pool for the ONT

that functions as a gateway. After the configuration, the PC connected to the LAN port can

automatically obtain an IP address from the address pool, as shown in

Figure 3-15

.

Parameter

Description

Enable DHCP L2 Relay

Indicates whether to enable the DHCP L2

Relay.

The DHCP relay is a process in which cross-

subnet forwarding of DHCP broadcast

packets is implemented between the DHCP

client and the DHCP server. In this manner,

the DHCP clients in different physical

subnets can obtain IP addresses which are

dynamically allocated from the same DHCP

server.

l

If

Mode

of the WAN port is

Route

, the IP

address of the ONT is obtained from

upper-layer DHCP servers in different

subnets and the user-side IP addresses are

obtained from the DHCP address pool of

the ONT.

l

If

Mode

of the WAN port is

Bridge

, the

ONT functions as a bridge. Thus, the ONT

does not have an IP address. The user-side

IP addresses are obtained from upper-

layer DHCP servers in different subnets.

Start IP Address

Indicates the start IP address in the IP address

pool on the primary DHCP server. It must be

in the same subnet as that of the IP address set

in "

LAN Host Configuration

". Otherwise,

the DHCP server fails to work normally.

End IP Address

Indicates the end IP address in the IP address

pool on the active DHCP server. It must be in

the same subnet as that of the IP address set

in "

LAN Host Configuration

". Otherwise,

the DHCP server fails to work.

Leased Time

Indicates the lease time of the IP address pool

on the active DHCP server. Options: minute,

hour, day, and week.

Enable secondary DHCP server

Indicates whether to enable the secondary

DHCP server. If the check box is selected,

you can set the secondary DHCP server.

IP Address

Indicates the IP address of the secondary

DHCP server.

Subnet Mask

Indicates the subnet mask of the secondary

DHCP server.

Start IP Address

Indicates the start IP address in the IP address

pool on the secondary DHCP server.

Description

End IP Address

Indicates the end IP address in the IP address

pool on the secondary DHCP server.

Leased Time

Indicates the lease time of the IP address pool

on the secondary DHCP server. Options:

minute, hour, day, and week.

Option60

Indicates the option 60 field of the secondary

DHCP server. A user-side DHCP client can

obtain an IP address from the IP address pool

on the secondary DHCP server only when the

option 60 field carried by the user-side DHCP

client is the same as this setting.
