Overview of QPM

QoS Policy Manager (QPM) lets you analyze traffic throughput by application or service class, and then leverage that information to configure QoS policies to differentiate traffic and to define the QoS functions to be applied to each type of traffic flow.

By simplifying QoS policy definition and deployment, QPM makes it easier for you to create and manage end-to-end differentiated services in your network, thus making more efficient and economical use of your existing network resources. For example, you can deploy policies that ensure that your mission-critical applications always get the bandwidth required to run your business.

QPM is suitable for large-scale enterprise deployments, and IP telephony deployments, consisting of hundreds or thousands of devices. QPM facilitates management of large networks by providing advanced user authorization capabilities through integration with Cisco Access Control Server (ACS).

QPM runs on the CiscoWorks Common Services server, which can be installed as a standalone server, or as an add-on to CD One 5th Edition. CiscoWorks Common Services provides the infrastructure required by QPM to run from the CiscoWorks desktop environment, and also provides management of user roles and privileges, allowing you to control who gets access to specific tasks in QPM.

Hardware and Software Requirements

It is recommended to use a dedicated server for QPM to realize maximum performance.

Table 1-1 shows the hardware and software requirements for the QPM server.

Table 1-1: Server Hardware and Software Requirements

Hardware	IBM PC-compatible computer with Pentium IV, 1 GHz or faster processor.
Memory (RAM)	1 GB minimum
Available disk drive space	7 GB minimum. (The available disk space required depends on the tasks you want to do in QPM.) Note CiscoWorks Common Services installation requires 2 GB free disk space, therefore you should ensure that you have a minimum of 9 GB free disk space before you install CiscoWorks Common Services.
Software	One of the following: Windows 2000 Professional with Service Pack 2. Windows 2000 Server with Service Pack 2.
Browser	Microsoft Internet Explorer 5.5 or higher.

Table 1-2 shows the requirements for client systems.

Hardware

IBM PC-compatible computer with Pentium, 300 MHz or faster processor.

Operating System

One of the following:

Windows 98
Windows NT 4.0 Workstation
Windows NT 4.0 Server
Windows 2000 Professional
Windows 2000 Server

Browser

Microsoft Internet Explorer 5.5 or higher

Preparing for Installation

Before you install QPM, ensure the following:

CiscoWorks Common Services is already installed on the machine on which you are going to install QPM. (CiscoWorks Common Services installs the CiscoWorks2000 desktop, if is not already installed.)
The machine on which you are going to install QPM meets the requirements for running QPM. See Hardware and Software Requirements.

Note You can install QPM 3.0 on a machine that has QPM 2.x installed. You do not need to uninstall QPM 2.x.

If you want to use your QPM 2.1.x policy databases in QPM 3.0, you must first export them from QPM 2.1.x, using the QPM 2.1.x export utility. See "Exporting QPM 2.1.x Databases" for more information.
