C H A P T E R 1 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.
Chapter 1 Overview of the WAN Modeling Tools Functionality of the NMT Figure 1-1 shows the relationship between the applications that make up the Cisco WAN Modeling Tools. Figure 1-1 Relationship between the Cisco WAN Modeling Tools EXCEL CWM NMT netowork topology data NMT WANDL 49072 CND Functionality of the NMT The NMT is a menu driven application that enables you to model the behavior of both simple and complex networks.
Chapter 1 Overview of the WAN Modeling Tools Cisco Products Supported by the NMT Cisco Products Supported by the NMT New functionality is added in each release of the NMT to accurately reflect the current capabilities of the following Cisco equipment: • MGX 8850, MGX 8830, and MGX 8950 switches—Enables a wide range of user services to be supported by the BPX service node.
Chapter 1 Overview of the WAN Modeling Tools 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.
Chapter 1 Overview of the WAN Modeling Tools Gaps • 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.
Chapter 1 Overview of the WAN Modeling Tools Data Translation Tools Data Translation Tools The NMT Data Translation Tools use data exchanged between the NMT and other network design software aides to create a complex network model. These tools allow the NMT to interface with other Cisco products as well as third-party products. Table 1-1 describes the data translation tools.

Chapter 2 Installing the Cisco WAN Modeling Tools 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.
Chapter 2 Installing the Cisco WAN Modeling Tools Installing the NMT Step 4 If you are installing from a cd on a Solaris platform, perform the following steps: a. Enter the following command: volcheck b. Note Enter the following command: cp /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.
Chapter 2 Installing the Cisco WAN Modeling Tools Installing the NMT 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 Note Cisco recommends that you do not link NMT without the plug-ins. Note NMTcreates a directory under your home path called tmp.
Chapter 2 Installing the Cisco WAN Modeling Tools Installing the NMT Installing the NMT on a PC Platform To install NMT on the PC, follow these steps: Step 1 Run 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 2 The zip file will unzip in c:\nmt by default.
Chapter 2 Installing the Cisco WAN Modeling Tools 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.
Chapter 2 Installing the Cisco WAN Modeling Tools Removing NMT Step 3 Enter the cd command to move to one of your project directories: cd project_name Step 4 Enter the nmt command to start NMT: nmt Note Use the nmt -d command to start the program if you need to modify system parameters to ranges outside the scope of the current product line.

Chapter 4 Configuration Tables and Fields Feeders Implicit IGX and IPX feeders can be generated when an IGX is used as the hub, but only when the traffic demands on the IGX exceed the resources of one node. Therefore, if the hub is an IGX, and you want to design IGX or IPX feeders, it is better to make the feeders explicit. Implicit MGX 8820 feeders are generated when a BPX is used as a hub node, and the Bursty Traffic table contains connections designated for MGX 8220.

Preferred_Route field: Enter a series of node cross-connects, separated by equal signs (=).
Chapter 5 NMT Execute Commands Fail Analysis Command Fail Analysis Command Selecting Fail Analysis from the Execute menu allows you to create a situation where one or more lines fail. You can also generate a situation where the lines are failed one at a time (see the Simulate All menu choice). By failing a line, you can force the NMT to create alternative routes; the NMT does this by using the Automatic Routing Management algorithm.
Chapter 5 NMT Execute Commands Optimize Command Optimize Command The NMT provides several tools for optimizing network models that allow you to create a least-cost topology with selected links. When you select Optimize from the Execute menu, the NMT processes your configuration to design a least-facilities-cost network. The Optimize command eliminates unused links (links that are not used for routing traffic) from the topology.
Chapter 5 NMT Execute Commands Optimize Command Note Optimize is not supported for PNNI Networks. NMT Command Results Table 5-4 lists the possible reasons connections are not being routed over links with the route command. Table 5-4 Possible Causes for Connections not Routed Over Links Cause Solution Set the keep field to one or higher. Link has a zero in the keep field.
Chapter 5 NMT Execute Commands Optimize Command The following tables describe how to troubleshoot problems with Execute commands. Symptom IGX Links are using more bandwidth than expected for voice and data calls. Probable Causes Voice and Data (TS and NTS) connections on the IGX are translated into fast packets. When these 24 byte packets with 20 bytes of payload are inserted into cells, the packet header is not removed, and either one or two packets are inserted into the cell.

C H A P T E R 6 NMT Reports This chapter describes the different types of reports generated by the NMT. NMT ascii reports are generated with each run of either the Route command or the Optimize command. Some of these reports can be viewed from the Display menu. All can be written to disk from the Report menu. Define Input Screen determines which reports to include in the output file, and Generate creates and names the output file. Most reports are fairly straight forward in the information they present.
Chapter 6 NMT Reports Link Load Report The Link Load report displays the load resources on each link in the network, based on the static load model. In the example below, den-sea is a cell based link where the bandwidth is 92% utilized. This link contains 80000 cells for CBR ATM traffic, 7515 cells of frame relay, and has a statistical reserve of 600, which is not included in the total. There are 55 PVCs on the first link.
Chapter 6 NMT Reports ATM & FR Ports Report (or Bursty Data Ports Report) The ATM and FR Ports Report lists all ports for each site that supports a connection found in the Bursty Connection Table. This report is output in DBF format.

C H A P T E R 9 Configuration Extraction Tool This chapter describes how to use the Configuration Extraction Tool (CET). The CET extracts data from the Informix database used by the Cisco Wan Manager (CWM). The CET then formats the data into a standard .cnf file that can be read by the NMT. The CET works with CWM Releases 9.2 through 15.1.50. CET is included in the UNIX installation of NMT. For instructions on installing the CET see the chapter “Installing WAN Modeling Tools.
Chapter 9 Configuration Extraction Tool Using the CET Using the CET To extract data from CWM and generate an NMT-compatible .cnf file, perform the following steps: Step 1 For the best data consistency, make sure the network is not running any administration activities that add or delete network elements. Also, make sure you are in the correct working directory, and that the CET has been installed there.
Chapter 9 Configuration Extraction Tool Using the CET Step 4 This step is optional. If manual corrections are required on the output CNF file, you can make them once, and then automatically make them again with the 'adj2nmt' command. The command only updates fields that are missing from CWM or are not that reliable. The site names, and slot port information is used to match links and connections. Messages are generated for every change.
