About This Manual

This manual lists all commands that can be used in conjunction with the

LSB4. These commands can be used to configure the switch to specific needs,

such as limiting access to the switch or setting a particular data transfer rate.

All parameters to be used with a command are listed, as well as the correct

syntax for the command. For instructions on the various methods used to ex-

ecute commands, see Chapter 3 of the LSB4 Installation Guide,

LSB4 Reference Manual System Commands

2-1

Introduction

System commands are used to configure and display the LSB4Õs

non-switch

functions, such as incoming logins, password protection, and the host from

which software will be downloaded.

Some of the system commands require the user to have privileged status. To

learn how to obtain privileged status, see page 2-5.

Set/Define and Show/Monitor/List Commands

Set/Define and Show/Monitor/List commands appear frequently in this man-

ual. It is important to note the difference between these commands.

Set

makes

an immediate change, but is not permanent. (Changes made with the Set com-

mand can be made permanent using the Save command.) Conversely,

Define

makes a permanent change, but it doesn't take effect until the LSB4 is rebooted.

The Show and List commands function in a similar manner to the Set/Define

commands.

Show

displays the current settings (including those Set but not

saved as permanent changes).

Monitor

displays the same current information as

Show but is updated every three seconds. The

List

command displays perma-

nent settings.

Set/Define System

Set System

and Define System

accept the following parameters:

♦

Incoming: SpeciÞes login restrictions

♦

Name: Assigns a name to the LSB4

♦

to the LSB4

♦

Privileged Password: Changes the password required for

particular commands

♦

Prompt: Sets a custom prompt string

♦

Software: SpeciÞes the name of a Þle to be down-

loaded to the LSB4

Show/Monitor/List System

Show System, Monitor System, and List System commands display LSB4 status

and configuration.

Set Privileged

This command enables privileged status, permitting a user to enter an additional

set of commands.

2chapternumber

Define Port

will

take effect as soon as

the port is logged

out.
