:



Set up Port 3 & Port 4

’

s egress bandwidth to 4096K and Download and Upload

stream

’

s bandwidth to 8192K. In this way, both Port 3 & Port 4 are each allocated

4096K bandwidth.

Scenario II:

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

internet access. As illustrated in Figure 3, 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

traffic gets forwarded for Internet access as wished (the total bandwidth for Port 3 and Port 4

is 4Mbps), 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.

48

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 allow the total bandwidth for Port 3 and Port 4 to 4Mbps,

“

By

Port Only

”

and

“

By Port with Queue

”

Bandwidth Mode can be used to achieve this goal.

Select

“

By Port Only

”

:



Set up Download and Upload stream

’

s bandwidth to 4096K and leave Port 3 and Port 4

’

bandwidth setting to their default values. In this way, the total egress bandwidth for Port

3 and Port 4 is 4096K. For example, if Port 3 consumes 1024K bandwidth, Port 4

’

s

allowed egress bandwidth is 3072K.

50

Select

“

By Port with Queue

”

:



Select each port

’

s corresponding queue. Set Port 1, 2, 3, and 4

’

s queue to Q0 and

WAN

’

s queue to Q1.

By default, when

“

By Port with Queue

”

bandwidth mode is

selected, (Upstream & Downstream) CPU belongs to Q0 and this queue setting

for CPU can not be modified. For LAN and WAN traffic flow, please refer to

“

Traffic Flow for Bridge & NAT Mode

”

.



Set up reserved egress bandwidth for each queue. Set Queue 0

’

s bandwidth to 4096 (K)

and leave queue 1, 2 and 3 to their default setting. By doing so, the total egress

bandwidth for Port 3 and Port 4 is 4Mbps.
