Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco produ cts. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Chapter 1 Planning Your Installation

Determining Installation Options

Cisco NPS has two component programs:

• Design and Analysis

• Virtual Network Data Server

Before installing the component programs, select the computers where you want to install these
programs. Each computer must meet the system requirements for the program of interest, as described
in the System Requirements for Cisco Network Planning Solution chapter.

Note Although you can install Virtual Network Data Server and Design and Analysis on the same computer,

Cisco strongly recommends that you install these components on separate computers. Doing so will
achieve the best performance from each component. (Design and Analysis is usually installed on a user
desktop or laptop, while Virtual Network Data Server is usually installed on a server in the Network
Operations Center.)

After you complete this step, return to the “Installation Workflow” section on page 1-1.

Determining Installation Options

Product Licensing

Each component program in Cisco NPS— Design an d Analysi s and Virtual Network Data
Server—requires a corresponding license to be installed and available to that program. On startup, the
program contacts a License Server and requests a license; if it does not obtain a license, the program
does not start. The License Server is a daemon/process that runs on the host where a license is installed;
it handles license requests from component programs.

After you determine the licensing configuration you want, return to the “Installation Workflow” section

on page 1-1.

Restricted and Unrestricted Licenses

You can buy either Restricted or Unrestricted versions of the Cisco NPS program licenses. This
distinction determines the scope of authorized users:

• A Restricted license confines the user of a program to one IP network by default subnet class. This

means that the licensed program can be used only if the License Server is in the same classful IP
network. IP network connectivity between the program and server is required.

• An Unrestricted license offers the most flexibility for organizations that operate multiple IP

networks (as defined by default subnet class). Users can access licenses from within the same
classful IP network as the License Server as well as from up to 100 additional IP networks. These
networks must be defined in advance.

78-17023-01

Installation Guide for Cisco Network Planning Solution

1-3

Product Licensing

Selecting the License Type

When you install a component program, the installer asks you to specify the licensing mode. The options
are:

• Floating/Local (“Floating: serve licenses from this computer”)—If you select this option, the

program will request a license from a License Server running on the local computer.

• Floating/Remote (“Floating: access licenses from re mote server”)—If you select this option, the

program will request a license from a License Server running on a remote computer. (The installer
also prompts you for the hostname of the remote server.)

Floating mode enables multiple users to share a license for Design and Analysis. The following
section describes Floating mode in more detail.

• Standalone—This mode is available for Design and Analysis only. If you select this option, the

installed license is restricted to the local computer and the program can be run on that computer only .
(In essence, the program acts as its own License Server.) Select this option only if you want to
restrict the use of Design and Analysis to one com puter.

Chapter 1 Planning Your Installation

Floating Mode

Note Multiple users cannot share the same Design and Analysis license concurrently. Multiple concurrent

Floating mode enables multiple users to share a license for Design and Analysis. On startup, the program
communicates with the License Server automatically and “checks out” a license. When the program
closes, it returns the license to the License Server. Then the license is available for another Design and
Analysis user to start the program and check out the license. In Floating mode, the license is not
“node-locked,” but can “float” to different computers.

Design and Analysis sessions require an equivalent number of program licenses.

Although the Virtual Network Data Server license server must use Floating mode, its license is not
shared among multiple users. The Virtual Network Data Server operates automatically, "consuming" its
license continually. System administrators do not need a license to log in to and operate the system.

How Licensing Types and Modes Affect Who Can Use a License

Table 1-2 illustrates how the different license modes and restriction types determine which applications

can use a specific license.

class "B" IP network address, then all workstations with the same class "B" address as the License Server are considered to be on the same classful IP
network as the License Server.

Licensing Requirements

Note the following requirements:

• You must add the corresponding license as described in the “Adding a License: Workflow

Description” section on page 5-2. Installing a program and specifying the licensing o ptions does not

install the license itself.

• If you specify Floating (remote) licensing for a program, the specifi ed License Server must be

accessible (via a TCP/IP network) to that program, as described in the “Licensing Requirements”

section on page 1-5.

• Standalone mode is supported for Design and Analysis only.

78-17023-01

• You must use Floating mode for Design and Analysis if V irtual Netw ork Data Server is also r unning

on the same host.

In Table 1-3, all licenses are installed on one host (VNDS_1), which acts as the only License Server in

the network. The local Virtual Network Data Server program uses Floating/Local mode, while the
remote programs use Floating/Remote mode. This type of setup is recommended; because there is only
one License Server, it is easier to manage your licenses and configure programs.

1. Each installed program has a “license_server” preference that specifies where (that is, on which host) the program license is
installed. This preference is set when the program is installed (as described in the “Selecting the License Type” section on

page 1-4). On startup, the program reads this preference and contacts the License Server on the specified host.

2. The “license_server” preference determines whether the program is in Local or Remote mode. If you specify Floating (local)
mode when you install the program, the installer sets the “license_server” preference to (local host) and installs the License
Server software. If you specify Floating (Remote), the installer prompts you for the name or IP address of the License Server
host.

Chapter 1 Planning Your Installation

In Table 1-4, the Design and Analysis program is installed on DA_1 and two other hosts. Each
installation requests a license from DA_1. (Remember that if only one license is installed on the host,
only one Design and Analysis session can run at a time.) Virtual Ne twork Data S erver is installe d on a
separate host and is configured to obtain a license from a License Server installed on the local host.
