About This Manual

The

NETGEAR

®

GS108T Smart Switch Software Administration Manual

describes how to install,

configure, operate, and troubleshoot the GS108T Gigabit Smart Switch using its included

software. This book describes the software configuration procedures and explains the options

available within those procedures.

Who Should Use This Book

The information in this manual is intended for readers with intermediate to advanced system

management skills.

This document was created primarily for the system administrator who wishes to install and

configure the GS108T Smart Switch in a network. It assumes that the reader has a general

understanding of switch platforms and a basic knowledge of Ethernet and networking concepts. To

install this switch, it is not necessary to understand and use all of its capabilities. Once basic

configuration is performed, it will function in a network using its remaining factory default

settings. However, a greater level of configuration—anywhere from the basic up to the maximum

possible—will allow your network the full benefit of the switch’s features. The Web interface

simplifies this configuration at all levels.

How to Use This Book

This document describes configuration menu commands for the GS108T Smart Switch software.

The commands can all be accessed from the Web interface.

•

Chapter 1, “Getting Started with Switch Management

,” describes how to use the Smart

Wizard Discovery utility to set up your switch so that you can communicate with it.

•

Chapter 2, “Introduction to the Web Browser Interface

,” introduces the Web browser

interface.

•

Chapter 3, “Managing System Settings

,” describes how to configure the system functions.

•

Chapter 4, “Configuring Switching

,” describes how to configure the switching functions.

•

Chapter 5, “Configuring QoS and Security

,” describes how to configure QoS and security

functions.
