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 1.0 server, which can be installed as a standalone server, or as an add-on to CD One 5th Edition. CiscoWorks Common Services 1.0 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.
Do not install Common Services 1.0 or QPM CDs on a Windows server running any of the following services:
•Terminal server
•Primary domain controller
•Backup domain controller
Do not install QPM on the same server as CiscoWorks Management Center for Routers (Router MC).
Table 1-1 shows the hardware and software requirements for the QPM server.
Caution If the QPM server does not meet the recommended system requirements, QPM startup and performance might be slow, or QPM might not work at all on the server.

•7 GB minimum. (The available disk space required depends on the tasks you want to do in QPM.)
Note CiscoWorks Common Services 1.0 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 1.0.

Preparing for Installation
Note If you are upgrading from QPM 3.0.x, see Installation Sequence to Upgrade from QPM 3.0.x for the recommended installation sequence.
Before you install QPM, ensure the following:
•CiscoWorks Common Services 1.0 is already installed on the machine on which you are going to install QPM. (CiscoWorks Common Services 1.0 installs the CiscoWorks 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 3.1 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 3.1, you must first export them from QPM 2.1.x, using the QPM 2.1.x export utility. See Appendix B, "Exporting QPM 2.1.x Databases" for more information.
Installation Sequence to Upgrade from QPM 3.0.x
If QPM 3.0.x is already installed on the server, use the following installation sequence to upgrade from QPM 3.0.x:
1. (Recommended) Export QPM database and configuration information from QPM 3.0.x using the export.exe utility on the QPM 3.1 installation CD. See Exporting QPM 3.x Information, page 3-1 for details.
2. (Required) Uninstall QPM 3.0.x.
3. (Required) Install QPM 3.1. See Installing QPM, page 2-1 for details.
4. QPM permission roles have changed in QPM 3.1. Before you begin to work with QPM, ensure that you have the appropriate permissions. See Working with User Permissions, page A-1 for details.
If you are working with ACS user permissions, register the new QPM user permissions in CiscoWorks and ACS. See Updating QPM 3.1 User Permissions in ACS, page 2-6 for details.
5. (Optional) Import QPM 3.0.x data into QPM 3.1 using the import.exe utility on the QPM 3.1 installation CD, or on the QPM server. See Importing QPM 3.x Information, page 3-3 for details.
Note Imported QPM 3.0.x IP telephony templates will overwrite any QPM 3.1 updated templates with the same name. To reinstall the updated templates after import, delete the old templates, and rerun the IP Telephony wizard. For details of changes to IP Telephony templates in QPM 3.1, see the Release Notes for QPM 3.1.
