of licensee’s facilities to which the Equipment may be transferred, for the useful life of the Equipment unless
earlier terminated by default or cancellation. Use of the Software shall be limited to such Equipment and to such
facility. Software which is licensed for use on hardware not offered by Bay Networks is not subject to restricted
use on any Equipment, however, unless otherwise specified on the Documentation, each licensed copy of such
Software may only be installed on one hardware item at any time.

2. Licensee may use the Software with backup Equipment only if the Equipment with which or for which it was
acquired is inoperative.

3. Licensee may make a single copy of the Software (but not firmware) for safekeeping (archives) or backup
purposes.

4. Licensee may modify Software (but not firmware), or combine it with other software, subject to the provision
that those portions of the resulting software which incorporate Software are subject to the restrictions of this
license. Licensee shall not make the resulting software available for use by any third party.

5. Neither title nor ownership to Software passes to licensee.

6. Licensee shall not provide, or otherwise make available, any Software, in whole or in part, in any form, to any

About This Guide

If you are responsible for configuring and managing Bay Networks routers, read
this guide to learn how to customize router software for LNM services. The LNM
Servers are the Bay Networks implementation of the five LAN management
servers described in the IBM Token Ring Architecture Reference.

Configuring LNM Services offers

• An overview of the LNM routing protocol and a description of how Bay
Networks routing servers work (Chapter 1)

• Implementation notes that may affect how you configure LNM Servers
(Chapter 2)

• Instructions on enabling LNM Servers (Chapter 3)

• Instructions on editing LNM global and interface parameters and configuring
LNM Servers (Chapter 4)

Before You Begin

Before using this guide, you must complete the following procedures:

• Create and save a configuration file that has at least one set of LNM Servers
and a Source Routing Bridge interface.

• Retrieve the configuration file in local, remote, or dynamic mode.

Refer to Configuring Routers for instructions.

Bay Networks Information Services

Bay Networks Information Services provide up-to-date support information as a
first-line resource for network administration, expansion, and maintenance. This
information is available from a variety of sources.

World Wide Web

The Bay Networks Customer Support Web Server offers a diverse library of
technical documents, software agents, and other important technical information
to Bay Networks customers and partners.

A special benefit for contracted customers and resellers is the ability to access the
Web Server to perform Case Management. This feature enables your support staff
to interact directly with the network experts in our worldwide Technical Response
Centers. A registered contact with a valid Site ID can

• View a listing of support cases and determine the current status of any open
case. Case history data includes severity designation, and telephone, e-mail,
or other logs associated with the case.

Technical Support and Online Services

• Customize the listing of cases according to a variety of criteria, including
date, severity, status, and case ID.

• Log notes to existing open cases.

• Create new cases for rapid, efficient handling of noncritical network
situations.

• Communicate directly via e-mail with the specific technical resources
assigned to your case.

The Bay Networks URL is http://www.baynetworks.com. Customer Service is a
menu item on that home page.
