Preface

The Cisco WAN Modeling Tools User Guide provides instructions for using the WAN Modeling Tools,

a design aid for WANs. The WAN Modeling Tools consist of the following software tools:

•Network Modeling Tool (NMT). UNIX and PC versions are available.

•Map Tool to display a graphical model of network topology.

•Configuration Extraction Tool (CET) for retrieving existing topologies from the Cisco Wan Manager

(CWM) database.

•Conversion Plug-ins: the Third-Party Interface (TPI) for sharing NMT information with WANDL

and the SpreadSheet Interface (SSI) for exchanging NMT configurations with Microsoft Excel.

These tools are integrated into NMT, but are also available as UNIX stand alone commands.

•Cisco Network Designer (CND) importing tool for importing and storing topologies in a project

format.

The guide is written for anyone who operates or manages a WAN and has a general understanding of

data communications concepts, some knowledge of UNIX and/or PC desktop, and knowledge of the

interfaces used by devices connected to their WAN.
