Implementing Quality of Service (QoS)

The QoS application delivers a set of tools that, when optimally configured, combat escalating
bandwidth costs and optimize application performance in your network.
QoS tools allow you to prioritize your critical applications and sensitive traffic. You can tailor
appropriate services to support this traffic over the wide area, thus maintaining the necessary
performance levels on an end-to-end basis.
To implement QoS, you need to configure the following:
QoS Summary parameters
QoS Devices
QoS Rules
QoS Actions
QoS Policies

Configuring the QoS Summary parameters

The QoS Summary parameters are global settings that affect all of the QoS Policies on your
system.
To configure the QoS Summary parameters:
1
On the navigation tree, click the Services key and click the Policy Management key.
2
Click the QoS heading.
The QoS Summary screen appears.
3
Configure the Summary parameters according to the following table.

Table 244 QoS Summary parameters

Setting
Definition
Description
Shows a description of the QoS service.
Version
Shows the version of the QoS service.
Status
Allows you to enable or disable QoS.
Premium
Enter the percentage of bandwidth to reserve for Premium traffic.
Bandwidth (%)
You can enter a value from 0% to 90%.
Note: If you set the Premium Bandwidth too high, you can starve out other traffic.
Video Class
Select the traffic category that is used for H.323 Video traffic.
You can assign video traffic as Premium or Best Effort.
Note: Choose Best Effort if you want to prevent IP Video traffic from competing with IP Telephony
traffic.
Premium DS
Enter the DiffServ Code used for Premium traffic on your network.
Code
The default value is 0xB8.
4
Click the Advanced tab.
The Advanced screen appears.
