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 Remote LANVIEW/Windows
User Manuals , or call Cabletron Systems at [phone].

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
F3 to access the Setup Directory. If
