Overview of QPM 4.1
This chapter contains the following topics:
What is QPM?
QoS Policy Manager (QPM) lets you analyze traffic throughput by application or service class, and then leverage that information to configure QoS policies . This allows you to differentiate traffic and 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. This allows you to use your existing network resources more efficiently and economically.
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 helps you to manage large networks by providing advanced user authorization capabilities through integration with Cisco Access Control Server (ACS).
QPM runs on the CiscoWorks Common Services server. CiscoWorks Common Services provides the infrastructure required by QPM to run from the CiscoWorks desktop environment. It allows you to manage user roles and privileges, and control user access to specific tasks in QPM.
QPM stores policy and device information in a relational database. Reports generated by QPM are stored separately as XML files. Monitoring task data is also stored separately.
QPM uses the CiscoWorks Common Services server to backup all application data.
Preparing to Install QPM
Before you install QPM, review the installation prerequisites and available installation paths to prevent problems during installation.

Hardware and Software Requirements
Hardware and Software Requirements
Table 1-1 shows the hardware and software requirements for the QPM server.
If the 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.
Table 1-1 Server Hardware and Software Requirements on Windows
Processor
Any of the following:
•
•
•
•
•

•
Hardware and RAM requirement
The number of CPUs and the RAM requirement depends on the number of devices:
•
•
Available disk drive space
A minimum of 9 GB.
CiscoWorks Common Services 3.2 requires 2 GB free disk space, therefore ensure that you have a minimum of 9 GB free disk space before you install CiscoWorks Common Services 3.2 and QPM.
The available disk space required also depends on the tasks you want to do in QPM. We recommend you to use 40 GB hard disk.
Monitor
Monitor with display set to High Color (16 Bit)
Software1
Any of the following:
•
•
•
•
•
•
•
•
Both 32 bit and 64 bit Operating Systems are supported on the above versions.
Browser (optional)
One of the following:
•
•
1 Common Services 3.2 supports only US-English and Japanese versions of Windows Operating Systems. It does not support any other language version. Installation might proceed normally in other locales but there might be problems in the functionality of CiscoWorks.
Table 1-2 shows the requirements for client systems.
Installation Prerequisites
We recommend that you use a dedicated server for QPM for maximum performance.
If you cannot use a dedicated server for QPM, you can install QPM on a Common Services server with LAN Management Solution (LMS) 3.1.
Prerequisites for Installing QPM
Before you install QPM, ensure that:
•
•
The QPM installation DVD contains Common Services 3.2 installation files. For more information, see Chapter 2, "Installing and Uninstalling QPM."

Installation Paths
If you have other CiscoWorks products installed on your server, review the information in Table 1-3 to determine the installation path required for QoS Policy Manager to successfully operate.
Table 1-3 Recommended Installation Paths 1
Has no other CiscoWorks products
Install (from the QPM 4.1 DVD):
1.
2.
Has LMS 3.1
Install QoS Policy Manager 4.1 (from the DVD).
We recommend that QPM should be the last application to be installed on LMS server.
Has QPM 4.0 or QPM 4.0.x, with Common Services 3.0.5
Install (from the QPM 4.1 DVD):
1.
2.
The QPM and CS application data is automatically migrated to QPM 4.1
1 QPM 4.1 does not support inline and remote upgrade from QPM 3.2.3.
