Port End:

Specify the ending TCP port number from 0 to 65535.

NOTE:

The range of starting and ending TCP port number should not be over 255.

Otherwise, an error message will pop-up when you click

“

Submit

”

button.

Reserve BW:

Specify reserved bandwidth for each queue (Queue-0 ~ Queue3).

2.6.2.2 Ingress Bandwidth Setting

This section describes how to setup the ingress bandwidth for Port 1 ~ 4 and WAN port.

Enabler:

Disable or enable bandwidth control function for Port 1 ~ 4 and WAN port.

Bandwidth:

Specify bandwidth for each port (Port 1~4 and WAN port).

2.6.3 Configure VLAN

Select

Configure VLAN

from the

Switch Management

menu,

then

Configure VLAN

screen page appears.

Default VLAN VID:

Specify a default VID number (1~4095) to each port.

Ingress Double Tag:

Enable or disable

“

Ingress Double Tag

”

function. When enabled,

ingress traffic is added with a PVID. The Residential Gateway supports Q-in-Q (Double tag

tunneling) for security via robust isolation of customer traffic and unburdening the service

provider from configuration management of CPE.

VLAN Forwarding Table

VID:

Specify a VID for new VLAN rule.

NOTE:

By default, there are two VLANs in the VLAN Forwarding table; VLAN 1 is for

WAN, VLAN 2 is for LAN. When you select your desired

“

NAT/Bridge Mode

”

in

WAN

Settings

, the settings in VLAN 1 and VLAN 2 will be changed accordingly and

automatically.

P-Bit:

Select a priority value from the drop-down menu for this VLAN rule.

Port:

T (Tag, a member in this VLAN rule), U (Un-tag, a member in this VLAN rule),

–

(Not a

member in this VLAN rule).

Click the

“

Insert

”

button to add this new rule to the VLAN table below after you enter the

new VID and select appropriate settings from the drop-down menu

Click the

“

Edit

”

button on the VLAN rule that you would like to make some changes. When

the selected port is highlighted in blue, users can make some changes by selecting from the

drop-down menu.

Click the

“

Change

”

button to apply the changes. The modified changes will apply to the

VLAN table immediately.

2.6.4 Traffic Flow for Bridge & NAT Mode

The Residential Gateway provides four physical 10/100Base-TX ports located on the front

panel and one physical WAN port inside the device (interfaces vary depending on the model

that you purchased). However, there are two more ports that are not explicitly shown in the

interface but might largely affect the traffic flow when you use Bridge/NAT mode; these are

Upstream port and Downstream port.

In normal operations, when packets received from the WAN port and destined for ports

assigned in Bridge Mode, they will be delivered directly to these ports. On the other hand,

for traffic flow destined for ports assigned in NAT mode, they will be delivered to

Downstream port (WAN CPU) first and then to Upstream port (LAN CPU) for delivering

traffic to NAT ports. For example, if you set NAT/Bridge Mode to

“

Mode 2: 3 WAN & 2 LAN

”

,

the traffic flow from the WAN port to two Bridge ports are illustrated below in Figure 1 and

the traffic flow from the WAN port to two NAT ports are illustrated in Figure 2.

Figure 1: Traffic Flow for Bridge Mode

Figure 2: Traffic Flow for NAT Mode

When setting up the desired bandwidth for each port or queue in your networking

environment, it is strongly recommended to consider the traffic flow for ports assigned in

Bridge and NAT Mode.

2.6.5 Bandwidth Control Setup Examples

Scenario I:

In this scenario, the WLAN Residential Gateway supports both IPTV applications and

internet access. As illustrated below, IPTV applications are connected to Port 1 (P1) and

Port 2 (P2); whereas, PC devices are connected to Port 3 (P3) and Port 4 (P4) to access the

internet. If you would like the WLAN Residential Gateway to control how much egress traffic

gets forwarded for Internet access as wished (4Mbps for P3 and P4 each), you can follow

the suggested setup steps below.

Step 1. Set Up NAT/Bridge Mode

In the scenario provided,

“

Mode 2: 3 WAN & 2 LAN

”

can be selected to group the WAN port,

Port 1 & 2 to Bridge Mode and Port 3 & 4 to NAT Mode.

Step 2. Set Up Default VLAN ID



Set up WAN

’

s Default VLAN ID to 24 then NAT Interface

’

s will be changed to the same

one automatically.



Set up Port 1 and Port 2

’

s Default VLAN ID to 1100.



Click the

“

Submit

”

button to apply the settings.

Step 3. Set Up VLAN Forwarding Table



According to the scenario provided, VID 24 should have NAT Interface untagged and

WAN tagged.



According to the scenario provided, VID 1100 should have WAN tagged and Port 1 and

Port 2 untagged.

Step 4. Set Up Egress QoS Control

In this scenario,

“

Bandwidth Control

”

can be configured to control the outbound (egress)

bandwidth to PC devices. To limit the bandwidth to 4Mbps for both Port 3 and Port 4,

“

By

Port Only

”

Bandwidth Mode can be used to achieve this goal.
