Who Should Read This Guide

The Network Registrar Concepts Guide is written for system evaluators and administrators. It assumes you understand how your site is configured, and are familiar with TCP/IP networking. The intent of the manual is to provide you with conceptual information about Network Registrar features to enable you to better configure and maintain your system.

How This Guide Is Organized

This guide is intended to be used when you are planning your installation or to learn about features that you have not yet used. The major sections of this guide are as follows:

Chapter 1	Network Registrar Features	Provides an overview of the Network Registrar features and indicates where to find the documentation.
Chapter 2	Client-Class	Describes the client-class facility, which allows you to provide differentiated services to users, and ensure that users automatically receive the appropriate class of service when they access the network
Chapter 3	DHCP Failover	Describes DHCP failover, which allows you to configure two servers to operate as a redundant pair of DHCP servers so that if one server is down, the other server seamlessly takes over and allows existing DHCP clients to keep and renew their IP leases.
Chapter 4	Data Import and Export	Describes the number of ways that you can import and export data. How you can generate the import files from a different external sources, and that you can use the export files as reports in themselves, or you can import the data into external databases and spreadsheets.
Chapter 5	SNMP Notification	Describes the Network Registrar SNMP (Simple Network Management Protocol) trap support that allows you to be warned of error conditions and possible problems with the Network Registrar DNS and DHCP servers, and to monitor threshold conditions that may indicate impending failure conditions.
Chapter 6	Configuration Guidelines	Describes hardware and software configuration guidelines for small, medium and large sites.
Chapter 7	LDAP	Describes the Lightweight Directory Access Protocol and how it can be used with Network Registrar.
Chapter 8	Extension Points	Describes the Network Registrar DHCP extensions, which you can use to affect the way the Network Registrar DHCP server handles requests, the way it responds to requests, and to change the behavior of Network Registrar after an extension is run.

Document Conventions

Network management interfaces use the following conventions:

• Command paths in a GUI are indicated as follows: Tools>VC List >All Connections

• NT systems use a two-button mouse. To drag and drop using an NT system, press and hold down the left mouse button on the icon you want to drag, drag it to the target, and release it to drop the icon on the target.

• UNIX systems use a three-button mouse. To drag and drop using a UNIX system, press and hold down the middle mouse button on the icon you want to drag, drag it to the target, and release it to drop the icon on the target.

• Screen displays may differ slightly from those included in this guide depending on the window system you are using. For example, Windows NT screens are different from HP OpenView screens.
