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,
Set-Up and
Operation
.

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
♦
Login Password: Changes the password required to login
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.
