To configure variable bandwidth of 2 Mbps for MOD data connection, select

Realtime VBR

in the

(divide the bandwidth 2mbps by 424) and

set both the

Sustain Cell Rate

and

Maximum Burst Size

as

4716

(which is less than the peak

cell rate). Click

Apply

to save the settings.

Configuring Port Binding

You can then group specific WAN PVCs with LAN ports or WLANs, so traffic from these ports is

forwarded through specific WAN PVCs. In the configuration shown below, the WAN connections set

up in the previous section are bound as follows:

1

Access the port binding screen by clicking

Network Setting

>

Port Binding

, and select

Activated

Port Binding

to turn on the port binding feature.

2

Click the

Port Binding

Configuring QoS to Prioritize Traffic

This section contains tutorials on how you can configure the QoS screen.

Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic

because your task includes sending urgent updates to clients at least twice every hour. You also

upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your

colleagues use the Internet for research, as well as chat applications for communicating with other

branch offices.

In the following figure you want to configure QoS so that e-mail traffic gets the highest priority. You

can do the following:

•

Configure a queue to assign the highest priority queue (1) to e-mail traffic from the LAN

interface, so that e-mail traffic would not get delayed when there is network congestion.

•

Note the MAC address (AA:FF:AA:FF:AA:FF for example) of your computer and map it to queue

1.

Note: QoS is applied to traffic flowing out of the AMG1302/AMG1202-TSeries.

Traffic that does not match this class is assigned a priority queue based on the internal QoS

mapping table on the AMG1302/AMG1202-TSeries.

DSL

E-mail: Queue 1

Your computer

A colleague’s computer

Other traffic: Automatic classifier
