CHAPTER 1
INTRODUCTION
Welcome to the Cabletron Systems ESX-1320/ESX-1380 Local
Management Guide
for the ESX-1320 and ESX-1380 Ethernet
Workgroup Switches. This manual explains how to access and use
Cabletron Systems Local Management for the ESX. Local Management
provides monitoring and control capabilities for the ESX and its attached
segments.
The ESX-1320 and ESX-1380 Ethernet Workgroup Switches, shown in
Figure 1-1, are standalone network switch devices. Except for the
difference in the network Media supported (ESX-1320, RJ45Twisted Pair
ports and ESX-1380, Multimode Fiber Optic ST ports), the two ESX
switches are identical in operation.
Figure 1-1 ESX-1320 and ESX-1380 Switches
NOTE
Throughout this manual the term ESX refers to both switches,
the ESX-1320 and the ESX-1380. If the information applies to
only one of the switches, then that switch is referred to by its
model name, ESX-1320 or ESX-1380.

1.2 DOCUMENT CONVENTIONS
The following conventions are used throughout this document:
1.3 LOCAL MANAGEMENT OVERVIEW
Cabletron Systems Local Management is a management tool that allows a
network manager to perform the following tasks:
• Configure the devices interconnected to form a network
• Monitor the network’s performance
• Control user access to the network and its components for the purpose
of security
NOTE
Note symbol. Calls the reader’s attention to any item of
information that may be of special importance.
TIP
Tip symbol. Conveys helpful hints concerning procedures or
actions.
!
CAUTION
Caution symbol. Contains information essential to avoid
damage to the equipment.

Chapter 1: Introduction
1-4 ESX-1320/ESX-1380 Local Management Guide
1.3.1 The Management Agent
The management agent is a process within the ESX which collects
statistical information (e.g., frames received, errors detected) about the
managed network’s operational performance. Local Management
communicates with the management agent for the purpose of viewing
statistics or issuing management commands.
1.3.2 In-Band vs. Out-of-Band
Network management systems are often classified as either in-band or
out-of-band. In-band network management passes data along the same
medium (cables, frequencies) used by all other stations on the network.
An example of an in-band network management system is Cabletron
Systems SPECTRUM.
Out-of-band network management passes data along a medium that is
entirely separate from the network’s common data carrier, for example, a
cable connection between a dumb terminal and the ESX COM port.
Cabletron Systems Local Management is an out-of-band network
management system.
A device connected out-of-band to the management agent is not
connected to the LAN. This type of connection allows you to
communicate with a network device even when that device is unable to
communicate through the network, for example, at the time of
installation.
1.3.3 Local vs. Remote Management
Network management applications are usually described as either local or
remote management applications. Local Management applications reside
within the management device’s management agent. Remote
management applications run within the circuits of another device that
provides management services. This allows you to perform network
management from a remote location.

Local Management Requirements
ESX-1320/ESX-1380 Local Management Guide 1-5
1.4 LOCAL MANAGEMENT REQUIREMENTS
The ESX provides two communication ports, labeled COM 1 and COM 2,
that support a management terminal connection. To access Local
Management, connect one of the following systems to either COM 1 or
COM 2:
• Digital Equipment Corporation VT series terminal
• VT type terminal running emulation programs for the Digital
Equipment Corporation VT series
• IBM or compatible PC running a VT series emulation software
package
You can also access Local Management using a Telnet connection
through one of the ESX network ports.
Chapter 2,
Local Management Requirements , describes the setup
requirements for accessing Local Management. It also explains how to
configure a management terminal and connect it to the ESX.

The following list explains each of the Local Management fields:
Event Message Field
This field briefly displays messages that indicate if a Local Management
procedure was executed correctly or incorrectly, that changes were saved
or not saved to Non-Volatile RandomAccess Memory (NVRAM), or that
a user did not have access privileges to an application.
Table 1-1 describes the most common event messages. Event messages
related to specific Local Management applications are described with
those applications throughout this manual.
Display Fields
Display fields cannot be edited. These fields may display information
which never changes, or information which may change as a result of
Local Management operations, user selections, or network monitoring
information.
Input Fields
Input fields require the entry of keyboard characters. IP addresses, System
Date, and System Time are examples of Input fields.
Selection Fields
Selection fields provide a series of possible values. Only applicable values
appear in Selection fields.
Command Fields
Command fields are located at the bottom of Local Management screens.
Command fields are used to exit Local Management screens and to save
Local Management entries.
Table 1-1 Event Messages
Message What it Means
SAVED OK One or more fields were modified,
and saved to NVRAM.
NOT SAVED?--PRESS SAVE TO
KEEP CHANGES One or more fields were modified, but not saved to NVRAM.
NOTHING TO SAVE The SAVE command was executed,
but nothing was saved to NVRAM.

1.6 LOCAL MANAGEMENT KEYBOARD
CONVENTIONS
All key names appear in this manual as capital letters. For example, the
Enter key appears as ENTER, the Escape key appears as ESC, and the
Backspace key appears as BACKSPACE. The table below explains the
keyboard conventions used in this manual as well as the key functions.
Key Function
ENTER and RETURN These are selection keys that perform
the same Local Management
function. For example, “Press
ENTER” means that you can press
either ENTER or RETURN, unless
this manual specifically instructs you
otherwise.
ESC This key lets you escape from a Local
Management screen without saving
your changes.For example, “Press
ESC twice” means that you must
quickly press the escape key two
times to exit the Local Management
screen.
SPACE bar and BACKSPACE These keys cycle through selections
in some Local Management fields.
Use the SPACE bar to cycle forward
through selections and use
BACKSPACE to cycle backward
through selections.
Arrows These are navigation keys.Use the
UP-ARROW, DOWN-ARROW,
LEFT-ARROW, and RIGHT-ARROW
keys to move the screen cursor. For
example, “Use the arrow keys”
means to press whichever arrow key
moves the cursor to the desired field
on the Local Management screen.

Navigating Local Management Screens
ESX-1320/ESX-1380 Local Management Guide 1-9
1.7 NAVIGATING LOCAL MANAGEMENT SCREENS
To navigate within a Local Management screen, use the arrow keys of the
terminal or the workstation providing terminal emulation services. The
Local Management screen cursor responds to the LEFT, RIGHT, UP, and
DOWN arrow keys. Each time you press an arrow key, the Local
Management screen cursor moves to the next available field in the
direction of the arrow key.
The Local Management screen cursor only moves to fields which can be
selected or used for input. This means that the cursor jumps over display
fields and empty lines on the Local Management screen.
The Local Management screen cursor provides wrap-around operation.
This means that a cursor located at the edge of a screen, when moved in
the direction of that edge, “wraps around” to the outermost selectable
item on the opposite side of the screen which is on the same line or
column.
[+/=] This key increments values in some
Local Management selection fields.
For example, “Press [ +/= ]” means to
press the plus/equal key.
[ – ] Key This key decreases values from some
Local Management selection fields.
For example, “Press [ – ]” means to
press the minus key.
DEL The DEL (Delete) key removes
characters from a Local Management
Selection field. For example, “Press
DEL” means to press the delete key.
