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 helps you to differentiate the 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

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 Solaris 

Processor	Any of the following: •UltraSparc III (280R, 480R) •UltraSparc IIIi Processor (V240, V250, V440), Sun Fire v210 •UltraSparc IV Processor (V490, V890) •UltraSparc T1 Processor (Sun Fire T1000 Server, Sun Fire T2000 Server)
Hardware and RAM requirement	The number of CPUs and the RAM size depends on the number of devices: •For around 2500 devices—2 CPUs with 2GB RAM memory requirement with a swap space of 4 GB •For around 10000 devices—2 CPUs with 4GB RAM memory requirement with a swap space of 8 GB
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	•Solaris 9, Solaris 10 We recommend that you install the Solaris Operating System in any of the following modes: •Entire Distribution •Entire Distribution plus OEM Support •End User System Support
Browser (optional)	•Firefox 2.0

1 Common Services 3.2 supports only US-English and Japanese versions of Solaris 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.

Table 1-2 Client Requirements 

System hardware and software	The hardware recommended for the client systems are: •Windows systems: PC-compatible system with single CPU 2.4 GHz or equivalent processor running: –Windows Server 2003 Standard and Enterprise Editions with Service Pack 1 and 2 –Windows Server 2003 R2 Standard and Enterprise Editions with Service Pack 1 and 2 –Windows XP Professional with Service Pack 2, Service Pack 3 –Windows Vista Business Edition with Service Pack 1 •Solaris systems: Sun UltraSPARC processor with Solaris 10 with latest patches and upgrades.
Memory requirements	1GB minimum RAM Either of the following: •For Solaris: 2GB swap space •For Windows: 2GB virtual memory We recommend that you set virtual memory and swap space to twice the size of RAM.
Monitor	Monitor with display set to High Color (16 Bit)
Browser	•Internet Explorer 6.0 Service Pack 1, Service Pack 2 •Internet Explorer 7.0 •Firefox 2.0 (for Solaris 10 client)
Plug-ins	•Adobe Flash Player 9 or later

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 the following:

•The machine on which you are going to install QPM meets the requirements for running QPM. See Hardware and Software Requirements.

•CiscoWorks Common Services 3.2 must be installed on the machine before you begin to install QPM.

The QPM installation DVD contains Common Services 3.2 installation files. For more information, see Chapter 2, "Installing and Uninstalling QPM."

•Set the desktop display to High Color (16 Bit). You can set the color depth under Display Properties > Settings on your desktop.

Prerequisites for Installing Common Services

Before you install CiscoWorks Common Services, ensure that you download and install the latest required and recommended patches for Solaris 8 and Solaris 9 from www.sun.com.

•The required patches are mandatory for all Common Services features to function properly.

•The recommended patches are optional. Some of the Common Services features may not work if these patches are not installed on your system.

Table 1-3 lists the required and recommended patches for Solaris 8 and Solaris 9.

Table 1-3 Solaris Patches¹  

Operating System	Required		Recommended
	Server	Client	Server	Client
Solaris 9	114224-01 113580-01 112839-04 112233-12 114006-01	112771-14 112661-06 113244-05	113326-01 112998-03 113713-14 112964-07 113575-05 112970-07 112874-31	112808-06
Solaris 10	•Required Server Patch is 122032-05. •Minimum system level must be 11/06 release or higher. To find out the current operating system level, enter the following command: # more /etc/release For example, the system displays the following information: Solaris 10 11/06 s10s_u2wos_09a SPARC Copyright 2006 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 11 November 2006

1 Use the showrev -p command to verify that these patches have been applied.

Installation Paths

If you have other CiscoWorks products installed on your server, review the information in Table 1-4 to determine the installation path required for QoS Policy Manager to successfully operate.

Table 1-4 Recommended Installation Paths 

If You are Installing QoS Policy Manager on a System That...	Then You Must...
Has no other CiscoWorks products	Install (from the QPM 4.1 DVD): 1. Common Services 3.2 2. QoS Policy Manager 4.1
Has LMS 3.1	Install QoS Policy Manager 4.1 (from the DVD)
Has QPM 4.0 or QPM 4.0.x, with Common Services 3.0.5	Install (from the QPM 4.1 DVD): 1. Common Services 3.2 2. QoS Policy Manager 4.1 The QPM and CS application data is automatically migrated.
