:
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.

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.

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.
