Preface
This guide provides the required information to setup and configure the ESB26 switch,
firmware version 3.3.0. It is intended for network administrators who are responsible for
installing and setting up network equipment. It assumes a basic working knowledge of the
following:
•Local area networks (LANs)
•Ethernet concepts
•Ethernet switching and bridging concepts
•Routing concepts
•Internet Protocol (IP) concepts
If the information in the Release Notes that are shipped with your unit differs from the
information in this guide, follow the Release Notes.
Conventions Used in This Guide
The syntax of CLI command lines, explained in "Basic CLI Operating Conventions" and the
further topics and discussed throughout this guide, is represented by the following general
format:
device-name>keyword(s) [parameter(s)] ... [keyword(s)] [parameter(s)]
OR
device-name[ (config ...)]#keyword(s) [parameter(s)]
... [keyword(s)] [parameter(s)]
where:
•The angle bracket (>) is the CLI prompt symbol in View mode.
•The pound symbol (#) is the CLI prompt symbol in all other modes.
•The left part, up to and including the prompt symbol represents the command prompt
displayed by the computer. In this part:
device-name stands for the name of the switch (e.g. ESB26).
The optional expression “(config)” or “(cfg ...)” – including the parentheses –
appears on the screen exactly as in the manual.
The part following the prompt symbol represents the users command. In this

part:
> keyword(s), in boldface characters, stands for one or more standard CLI
command keywords. The first keyword may optionally be preceded by no
to indicate a negation of the command.
> parameter(s) may be one or more optional or requisite values, depending
on the requirements of the specific command. They are represented by
slanted characters.
> In this guide, keywords and parameters may be separated by vertical OR
bars (|). The OR bars indicate an exclusive-or choice among a group of
selectable entities separated by these symbols.
> Parentheses and braces may be used in this guide to enclose selectable
entities – for the purpose of clarification.
