Preface

This preface provides an overview of this guide, describes guide conventions, and lists other useful

publications.

Introduction

This guide provides the required information to use the EPICenter software. It is intended for use by

network managers who are responsible for monitoring and managing Local Area Networks, and

assumes a basic working knowledge of:

●Local Area Networks (LANs)

●Ethernet concepts

●Ethernet switching and bridging concepts

●Routing concepts

●The Simple Network Management Protocol (SNMP)

NOTE

If the information in the Release Notes shipped with your software differs from the information in this guide, follow

the Release Note.

Terminology

When features, functionality, or operation is specific to the Summit, Alpine, or BlackDiamond switch

family, the family name is used. Explanations about features and operations that are the same across all

Extreme switch product families simply refer to the product as the “Extreme device” or “Extreme

switch.” Explanations about features that are the same for all devices managed by EPICenter (both

Extreme devices and others) are simply refer to “devices.”

Conventions

Table 1 and Table 2 list conventions that are used throughout this guide.

Table 1: Notice Icons

Icon Notice Type Alerts you to...

Note Important features or instructions.

Caution Risk of unintended consequences or loss of data.

Warning Risk of permanent loss of data.

Table 2: Text Conventions

Convention Description

Screen displays This typeface represents information as it appears on the screen.

Screen displays bold This typeface indicates how you would type a particular command.

The words “enter”

and “type”

When you see the word “enter” in this guide, you must type something, and then

press the Return or Enter key. Do not press the Return or Enter key when an

instruction simply says “type.”

[Key] names Key names appear in text in one of two ways. They may be

• referred to by their labels, such as “the Return key” or “the Escape key.”

• written with brackets, such as [Return] or [Esc].

If you must press two or more keys simultaneously, the key names are linked with a

plus sign (+). For example:

Press [Ctrl]+[Alt]+[Del].

Words in bold type Bold text indicates a button or field name.

Words in italicized type Italics emphasize a point or denote new terms at the place where they are defined in

the text.
