INTRODUCTION

Welcome to Cabletron Systems

MRXI/LM Local Management for

the Cabletron Systems MRXI 10BASE-T HUB User's Manual.

This manual serves as a simple reference guide for using MRXI/LM™,

providing information to help you configure the MRXI™ and MRXI-2

and, if necessary, diagnose problems with your network.

NOTE:

This manual covers both the MRXI and MRXI-2. The two units

are functionally identical. The MRXI provides connections for ports 1

through 12 via a 50 pin Champ connector, while the MRXI-2 provides

twelve RJ-45 connectors. Throughout this manual the term MRXI is

used to cover both units unless otherwise specified.

1.1 USING THIS MANUAL

Read through this manual to become familiar with its contents and to

gain an understanding of the features and capabilities of MRXI/LM. A

general working knowledge of Ethernet networks and the IEEE 802.3

standard is necessary for interpreting and using MRXI/LM.

Chapter 1,

Introduction,

outlines the contents of this manual, briefly

describes features and functions performed by the Hub and MRXI/LM,

and concludes with a list of related manuals.

Chapter 2,

Attaching the Console

, describes terminal

characteristics, connecting console cabling, and configuring the

management console.

Chapter 3,

Getting Started,

describes the initial steps required to

access MRXI/LM. It describes each of the screens and the available

commands.

Chapter4,

Using the Device/Board/Port Counters Screen

describes the status and statistics information available for the MRXI.

Chapter 5,

Using Community Names

, describes entering and using

a community names table.

Chapter 6,

MRXI/LM Messages

, explains messages that can appear

at the top of the MRXI/LM terminal display.

INTRODUCTION

1.2 THE MRXI

The MRXI 10BASE-T HUB and MRXI-2 10BASE-T HUB are 10BASE-

T and 802.3 compliant repeaters that allows expansion of existing

802.3 networks using a variety of media. The two hubs are identical

except for the physical connections for ports 1 through 12. The MRXI is

equipped with a 50 pin Champ connector, while the MRXI-2 provides

twelve RJ-45 connectors. The MRXI supports out-of-band and in-band

Simple Network Management Protocol (SNMP) compliant network

management. Out-of-band management for the MRXI is provided by

MRXI/LM. The MRXI is supported by several in-band network

management tools including: Cabletron Systems Remote LANVIEW/

Windows™, and SPECTRUM™.

1.3 THE MRXI/LM

The MRXI/LM is a menu driven, integrated network management tool

that permits management and control of the MRXI. MRXI/LM can be

used to:

• Display current MRXI status and statistics for the MRXI

network ports

• Define community names and access privileges

• Diagnose network problems.

The MRXI is an SNMP compliant device that permits setting

community names for your MRXI. The Community Names feature

serves two purposes:

• As a security feature that defines access privileges for SNMP

requests from SNMP management stations

• Community names let you to designate the network

management workstations that will receive alarms from the

MRXI.

You can access MRXI/LM through a management terminal connected

to the 9-pin Console port on the rear panel of the MRXI. The console

port supports a Digital Equipment Corporation, VT200™ or VT300™

series terminals or PC emulation of the VT200 or VT300 terminals.

1.4 REMOTE LANVIEW/WINDOWS

MRXI/LM provides the foundation for Remote LANVIEW/Windows,

Cabletron Systems Remote Network Control Management Software

package (This package can be purchased separately from Cabletron

Systems.). Remote LANVIEW/Windows allows you to control and

manage multiple MRXIs from a single Ethernet workstation. With

Remote LANVIEW/Windows, you can view statistics for your MRXI,

both numerically and graphically, using dynamic bar and pie charts

and

performance graphs. You can also enable a statistics logging and

reporting function that will log MRXI statistics to a report file for

future reference.

For more information on using Remote LANVIEW/Windows with the

MRXI, consult the Cabletron Systems

ATTACHING THE CONSOLE

This chapter describes information on the characteristics of supported

terminals, configuring the management console and connecting the

console cabling.

2.1 LOCAL MANAGEMENT CONSOLE

MRXI/LM is accessed by attaching a management console at the DB-9

CONSOLE port on the rear panel of the MRXI (see Figure 2-1). The

consoleconnectionsupportsaDigitalEquipmentCorporationVT200™

or VT300™ series terminal or PC emulation of one of these terminals.

Figure 2-1. Management Console Connection

Table 2-1 lists the setup requirements for the local management

console. If your terminal is a Digital Equipment Corporation VT200™

or VT300™ series terminal, press

to access the Setup Directory. If

you have a terminal emulation of the Digital Equipment terminals,

refer to your equipment user manual for setup procedures.
