To configure dedicated bandwidth of 400 kbps for the VoIP connection, select
CBR
in the
ATM QoS
Type
field and enter the
Peak Cell Rate
as
943
(divide the bandwidth 400000 bps by 424). Click
Apply
to save the settings.
To configure variable bandwidth of 2 Mbps for MOD data connection, select
Realtime VBR
in the
ATM QoS Type
field. Set the
Peak Cell Rate
as
4717
(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
tab, specify the
Group Index
and select the ports to include in the port
binding group. Click
Apply
.

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.
EXAMPLE
DSL
E-mail: Queue 1
Your computer
A colleague’s computer
Other traffic: Automatic classifier
MAC=AA:FF:AA:FF:AA:FF
