Choose - Advanced Setup>Quality of Service – To enable Quality of Service.
Quality of Service helps to prioritise data as it enters your router. By attaching
special identification marks or headers to incoming packets, QoS determines
which queue the packets enter, based on priority. This is useful when there are
certain types of data you want to give higher priority, such as voice data packets
give higher priority than Web data packets. This option will provide better service
of selected network traffic over various technologies.
With the 6401 Rugged Router traffic will generally enter the router from the Ethernet ports and will
be marked for transmission over the WAN port or via other Ethernet ports. The order of configuration
for Quality of Service should be;
1. Configure the interfaces – Ethernet and ATM
2. Enable - QoS Queue Management and Configuration
3. Configure the queues – QoS setup
4. Configure Traffic rules to match traffic and assign to the Queues.
Quality of Service is set up on three screens in the Quality of Service menu

down box
Step 3
Queue
Configuration
Configure a QoS
queue and assign
it to a specific
layer 2 interface.
The scheduler
algorithm is
defined by the
layer 2 interface
Step 4
QoS
Classification
Create traffic class rules
to classify upstream
traffic, assign a queue
which defines the
precedence and interface
and optionally
overwrites the DSCP
header.
A rule consists of
1. Class Name
2. One condition
