3.4.3.4 QoS Settings
The device's Quality of Service (QoS) provides the capability to provide better service to
selected network traffic. This is achieved by shaping the traffic and processing higher
priority traffic before lower priority traffic.
The QoS menu provides the following items:
îš„ General (refer to ''Configuring General QoS Settings'' on page 88)
îš„ Traffic Priorit
y (refer to ''Configuring Traffic Priority'' on page 88)
îš„ Traffic Shapi

3.4.3.4.1 Configuring General QoS Settings
The General item allows you to configure your WAN bandwidth.
¾ To configure the device's WAN bandwidth:
1. Click the General item (Configuration tab > Data Settings menu > QoS submenu >
General page item); the following page appears:
Figure 3-67: Configuring General WAN Bandwidth
2. From the 'WAN Devices Bandwidth (Rx/Tx)' drop-down list, select the required Rx/Tx
bandwidth. If you do not see an appropriate entry, select 'User Defined', and then enter
your Tx and Rx bandwidths in the fields below:
• 'Rx Bandwidth': defines the device's Internet traffic receiving rate (in Kbps).
• 'Tx Bandwidth': defines the device's outbound transmission rate (in Kbps).
Note: For correct QoS performance, ensure that the bandwidth values are correct.
3.4.3.4.2 Configuring Traffic Priority
Traffic Priority allows you to manage and avoid traffic congestion by defining inbound and
outbound priority rules for each element on your device. These rules determine the priority
assigned to the packets traveling through the element. QoS parameters (DSCP marking
and packet priority) are set per packet, on an application basis. You can set QoS
parameters using flexible rules, according to the following parameters:
îš„ Source/destination IP address, MAC address or host name
îš„ Device
