Overview of QPM 3.2
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 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 2.2 server with Common Services Service Pack 2. 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.
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.
The QPM database can be backed up using scheduled QPM backups. All QPM application data can be exported for backup purposes, or for migrating from one QPM server to another.
Preparing to Install QPM
Before you install QPM, review the installation prerequisites and available installation paths to prevent problems arising during the installation process.
