Overview of the WAN Modeling Tools
This chapter provides an overview of the applications that make up the Cisco WAN Modeling Tools, and
of the Cisco products they support.
Cisco WAN Modeling Tools Overview
Cisco WAN Modeling Tools includes the following tools:
• The Network Modeling Tool (NMT)
• The Configuration Extraction Tool (CET)
• The Third-Party Interface (TPI)
• The Spread Sheet Interface (SSI)
The NMT is the primary application of the Cisco WAN Modeling Tools. NMT verifies the provisioning
and predicts the routing behavior of the network. NMT supports the following Cisco MSSBU ATM
platforms:
CHAPTER
1
• MGX series
• BPX series
• IGX series
For each major switch software release, NMT verifies the physical and logical provisioning of the front
and back cards that support the specified topology. NMT also verifies connection routing and rerouting
capabilities of each supported switch in the network.
The CET, SSI, and TPI tools enable the exchange of information between the NMT and other
applications. These tools provide interfaces to CWM, Excel, and WANDL.

Functionality of the NMT
The NMT is a menu driven application that enables you to model the behavior of both simple and
complex networks. The program processes information provided by you and returns a proposed
configuration. This configuration can then be modified and reprocessed to add redundant links, support
additional sites, and so forth. You can also perform failure analysis of the network model by failing
selected links and then evaluating the rerouting capability of the remaining links. The NMT allows you
to interface to WANDL and other systems to further optimize the design.
Only a few fields need to be completed in order for the NMT to generate a configuration. To create the
best configuration possible,. you should have extensive knowledge of computer networks, including
ATM and Frame Relay networks. In addition, entering precise values for optional fields will help the
NMT provide you with a precise parts list that you can use to order Cisco products.
Once the NMT processes the data, it provides configuration information in the following form:
• Updated tables—Modifies your configuration tables as necessary to create a working configuration.
• Reports—Provides a series of reports that describe links, nodes, part numbers, costs, and so on.
• Graphical display—Displays your network design graphically with node icons and maps.
• Import/Export—Displays data imported/exported to other systems.
The NMT always selects the newest available parts for a function, based on the software release you
specify. You can explicitly request older cards from the input tables. Some obsolete parts are not
supported.

Basic Usage/Charter Functionality
• IGX switch—A multi-service ATM networking switch that provides interfaces to support legacy and
emerging broadband applications. It supports ATM technology over subrate, narrowband E1 and T1,
and broadband E3 and T3 trunks. The IGX switch is used as the basis for a leased-line campus,
metropolitan area network (MAN) and WAN network, as an intelligent access device to high
speed-public digital services such as ATM, in a hybrid application using both, and as a WAN service
switch.
• Generic Node -- The NMT allows you to create your own node type for an ATM switch or feeder.
Use the node table to provide the high level specifications for the WAN product.
• Obsolete Equipment -- The NMT models obsolete equipment that users may encounter in CWM
extracts, and need to model for upgrade considerations. The following obsolete platforms are
modeled:
IPX switch, 3810 feeder, FastPad feeder, Port Concentrator Shelf Feeder
Basic Usage/Charter Functionality
The NMT models the WAN network using a classic node, link, and demand model. The nodes are the
sites in the site table, which are provisioned as Cisco MSSBU WAN switches. The links are the inter
switch trunks in the link table. The connections are specified in the voice, data, and bursty table.
The model provisions the network using the latest Cisco equipment, unless otherwise specified. The
model will verify that the network will route all connections, or will report on what resources have been
exceeded.
Chapter 1 Overview of the WAN Modeling Tools
The NMT tool predicts the behavior of a WAN network that uses Cisco WAN switches (MGX, BPX and
IGX product series) as follows:
1. the user specifies the site locations and switch types, the links, and the connections in the network.
2. the NMT uses the AutoRoute and PNNI routing algorithms identical to those in the products.
3. based on the Connection Admission Control (CAC) parameters, the NMT verifies that the links and
connections can be provisioned, and that the connections can be routed.
4. the WAN network is modeled at the chassis, front card, and back card granularity level.
NoteAll connections used by the NMT are ATM connections, with the exception of some legacy IGX voice
and data services.
Keep the following in mind when you use the NMT:
• The NMT provides the primary reason any connections cannot be provisioned or routed, based on
the CAC rules.
• The NMT does not do discrete simulation, and no real time statistics are involved in the modeling.
• The NMT address the following real time issues only:
–
delay estimate
–
requirements specified in the CAC.
• The NMT verifies the connections routed in the base state
1-4
• The NMT verifies which connections will re-route under any network failure scenario.
Cisco WAN Modeling Tools Guide
OL-10426-01, Rev. A0
Chapter 1 Overview of the WAN Modeling Tools
• The NMT extracts the network topology and connection parameters from Cisco WAN Manager.
The NMT handles changes in the CWM DB schema, so these changes are invisible to the user. CWM
coded values are translated to more usable strings, and tables are merged so in NMT, there is 1 table
per network element.
• The NMT translates topology data to and from MS Excel data. The NMT tables are translated to
DBASE3 format and a MS Excel macro is provide for creating a file of spreadsheets for each table.
• NMT translates the topology data to and from the WANDL format for use by their NCAPS tool.
• PNNI CAC parameters are not as granular as they are in the product. For example, some parameters
are network specific.
• A 10 character node naming limitation is imposed. CWM provides translation for node naming.
Gaps
The following features are not supported by the NMT:
• XPVCs
• Voice traffic channel mapping entering the network for VISM/VXSM cards
Gaps
• IP traffic entering the network for RPM cards
• LVC resource support for RPM cards
• Port Partitioning by COS
• Priority bumping in AutoRoute
• VXSM card and connections terminated on that card
• PPP types of traffic on MPSM-16T1E1 cards
• MFR links and connections on MPSM-T3E3-155 cards
• Cisco MGX 8880 node (not supported by CWM)

Installing the NMT
Installing the NMT
This section explains how to install the Cisco WAN Modeling Tools software and link it to your project
directories. This procedure also installs any subapplications (CET, TPI, and SSI) that came with your
copy of the NMT software. If you want to install only the subapplications, refer to the “Installing a Cisco
WAN Modeling Tools Sub-application” section later in this chapter.
The NMT Product provides both a UNIX and PC version of the NMT tool. To install the NMT on a UNIX
platform, see the “Installing the NMT on a UNIX Platform” section that follows. To install the NMT on
a PC platform, see the “Installing the NMT on a PC Platform” section later in this chapter. The
differences between UNIX and PC version of the NMT are as follows:
• The PC version of NMT uses F5 for choice list, UNIX version uses HELP or F12.
• The PC version of NMT has no support to launch the MAP command.
NoteCNF files from either platform can be read by the other. For example, CNF files from a PC version of
NMT can be read by a UNIX version of NMT, and vice-versa.
Chapter 2 Installing the Cisco WAN Modeling Tools
Installing the NMT on a UNIX Platform
To run NMT on Unix platforms, you need to install the software first. Install the software once for each
release platform. Once the software is installed, you need to create a working directory from which you
will launch NMT.
Load the NMT Software
Use the following procedure to create a dedicated subdirectory that will store the NMT software. The
installation process creates a subdirectory name and a release number. For example:
/usr/users/NMT/151
NoteMultiple NMT feature releases can co-exist on the UNIX platform. If a maintenance upgrade is done,
the upgraded NMT release replaces the previous release.
To create the software installation directory, perform the following steps.
Step 1Log into the account that will own the NMT software.
Step 2Create a dedicated directory where the NMT releases are stored.
Step 3Verify that you are in the correct directory by entering the following command:
pwd
2-2
The path with the release number is the same path you will use when you create a working directory.

Chapter 2 Installing the Cisco WAN Modeling Tools
Step 4If you are installing from a cd on a Solaris platform, perform the following steps:
a. Enter the following command:
volcheck
b. Enter the following command:
Notecp /cdrom/nmt151/install/151.tar.Z
If this step fails because the file is not found, substitute nmt151#1 for nmt151.
c. Enter the following command:
uncompress 151.tar
d. Enter the following command:
tar xf 151.tar
This creates the 151 directory containing all the software.
Creating a Working Directory
Installing the NMT
Use the following procedure to link the NMT software to working or project directories.
NoteYou need to perform this procedure only once. Once you have created a working directory, you can
launch the NMT from the working directory.
Step 1Log into the account that will own the working NMT directory.
NoteThe account that owns the working directory can be the same account that owns the software directory,
or it can be a different account.
Step 2Create the working directory name:
mkdir project_name
Step 3Move to the subdirectory you just created:
cd project_name
Step 4Make sure you are running in c shell. If you are not, enter the following command:
csh
Step 5Link the project directory to the NMT release:
OL-10426-01, Rev. A0
a. Set the environment variable NMTHOME to the path of the software directory and release. For
example:
setenv NMTHOME /usr/users/NMT/151
b. Execute the following command:
$NMTHOME/nmtlink
Cisco WAN Modeling Tools Guide

Installing the NMT
Chapter 2 Installing the Cisco WAN Modeling Tools
The NMT files are linked or copied to the project_name directory. This links NMT and all the
plug-ins (including TPI, SSI, and CET). To link in NMT without the plug-ins, enter the following
command:
$NMTHOME/nmtlink -nmt
NoteCisco recommends that you do not link NMT without the plug-ins.
NoteNMTcreates a directory under your home path called tmp. If you want NMT to use a
different directory than tmp for scratch work, you can specify it with the full path by using
the environment variable NMTTMP.)
NoteCisco recommends that you periodically remove old files from the tmp/scratch work
directory. NMT must not be running when you remove files from this directory.
Figure 2-1 depicts the relationship between the NMT software, user, and project accounts.

Installing the NMT on a PC Platform
To install NMT on the PC, follow these steps:
Step 1Run the provided nmt installing exe file, which is a self extracting ZIP file. The file is called
‘nmt_inst.exe’ and is in the PC directory. You can either run it directly from your CD drive on the PC,
or transfer it from your UNIX installation to your PC and then run it.
Step 2The zip file will unzip in c:\nmt by default. It is recommend you keep this as the NMT installation
directory. If you accept this selection, move to step 3. If you wish to change the installation directory,
use one of the procedures that follow.
To change the installation directory on a Windows 2000 system, follow these steps:
a. Enter the cd command to get to the Advanced directory, as shown in the following example:
My Computers/Control Panel/System/Advanced.
b. Click “Environment Variables.”
c. Click “New” and add the environment variable with the name NMTHOME, and set the value to the
directory you specified when installing the compressed file.
Installing the NMT
To change the installation directory on earlier windows systems:
a. Add the lines in the file autoexec.add to the end of your autoexec.bat file. The autoexec.add file is
in the c:\nmt default directory, and the autoexec.bat is found in the c: main directory.
b. Change the drive and directory of NMTHOME to the path you entered for the unzip command.
c. Reboot your machine before running NMT.
Step 3Install the shortcut.
a. Open Explorer, go to \nmt\install and then to the sub directory of the operating system on your PC.
b. Drag and drop the Cisco WAN Modeling Tool shortcut to the background windows screen.
To create a short cut from scratch, follow these steps:
a. Use Explorer to drag and drop the file c:\nmt\install\nmt.exe to the background.
b. Right mouse click on the icon for properties.
c. Set start in to the recommended C:\nmt†ata, which will be the default directory for storying your
NMT files.
If you want to store your NMT data elsewhere, you can reset this. Select change icon, and then browse.
Select the file c:\nmt•in\nmt_icon.exe and pick the icon on the left.
Step 4Click the Cisco WAN Modeling Tool icon to start NMT. Alternatively, you can start NMT by running
c:\nmt\nmt.exe.

Upgrading the NMT Software
Upgrading the NMT Software
NMT feature releases have unique sub directory names. The installation of a new feature release requires
the creation or alteration of the working directories. Maintenance releases, however, use the same
software directory you created in the previous section. The working directories automatically use the
upgrade through UNIX links to the software.
Use the following procedure to perform a maintenance upgrade of NMT software on a UNIX system.
Step 1Enter the cd <directory> command to log onto the same account that was used to initially install the
software, as shown in the following example:
cd /usr/users/NMT
Step 2Copy the compressed tar file 151.0.tar.Z to the same directory in which the release was initially installed.
Step 3Enter the uncompress <filename> command to uncompress the file, as shown in the following example.
uncompress 151.0.tar
Chapter 2 Installing the Cisco WAN Modeling Tools
Step 4Enter the tar xf <filename> UNIX command to untar the file as shown in the following example:
tar xf 151.0.tar
Starting the NMT
Use the following steps to run the NMT and any NMT UNIX commands.
NoteAlways enter the commands in the NMT working directory.
Step 1If you are on a Cisco StrataView platform, while logged in as Cisco Wan Manager (CWM) and in the
svplus directory, enter the xhost + command to grant xwindows permission. (This can be done from the
console window or an xterm window.)
xhost +
NoteYou may want to add the xhost + command to the svplus.login file.
Step 2Enter your user name and enter your password to log in to your user home directory. For example,
/usr/users/my_name.

Installing a Cisco WAN Modeling Tools Sub-application
Installing the Cisco WAN Modeling Tools sub-applications on a UNIX Platform
Use the following procedure to install a Cisco WAN Modeling Tools sub-application on a UNIX
Platform.
Step 1Go to a working directory where you have run nmtlink.
Step 2Set up a UNIX environment variable for CET, TPI, or SSI.
setenv [nmt_path]
nmt_path is the path to the version of the NMT software you are using.
Step 3Link the project directory to the NMT release:
For CET: $CETHOME/cetlink
For TPI:
For SSI:
$TPIHOME/tpilink
$SSIHOME/ssilink
Installing the SSI on a PC Platform
Install the Spread Sheet Interface on the PC regardless of whether you use the PC or UNIX version of
NMT.
To install SSI on a PC, complete the following steps:
Step 1Transfer the following files to your PC:
• SSI—NMT Excel macro file. This macro converts DBF formatted NMT tables into an Excel
spreadsheet, and vice-versa.
• SSIDOSKT.TAR—Archive file of SSI DOS utilities tar.exe; DOS version of UNIX tar command.
These optional utilities support the transferring and uncompacting of data.
NoteUse binary mode when transferring SSI and SSIDOSKT.TAR to your PC.
Step 2Copy the file SSI to the XLStart subdirectory of your Excel 5.0 (or higher) installation. It can be installed
in any Windows environment.
NoteIn most PC Environments, Excel will be in the directory c:\program files\Microsoft
Office\Office\XLstart.
Step 3Copy the file to the xlstart subdirectory of the Excel product.
This Macro gives you the NMT_Load, NMT_Unload and NMT_PrettySheet commands.
