Introduction
How to use this guide; related guides; software conventions; getting help; IRM2 firmware versions
Welcome to the Enterasys Systems NetSight Element Manager for the IRM2
User’s Guide. We have designed this guide to serve as a simple reference for using
NetSight Element Manager for the IRM2.
The IRM2 is an IEEE 802.3-compliant repeater module designed to be installed in
a Cabletron Systems Multi Media Access Center (MMAC®) hub, either with or
without the Flexible Network Bus (FNB™). The IRM2 occupies the first
(management) slot of the MMAC hub, and controls non-intelligent Ethernet
modules installed to its left. It retimes and regenerates Ethernet data packets
throughout the chassis, and performs automated management such as port
segmentation. With NetSight Element Manager, you can gather a full array of
statistical information from the IRM2 at the device, board, and port levels —
including data throughput statistics and error breakdowns. You can also set
alarms and traps for the hub, configure redundant circuits, or set port security
parameters based on Ethernet source address locking.
Using This Manual
Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the IRM2 device module. This guide contains
information about software functions which are accessed directly from the device
icon; for information about functions which are accessed via the menu bar across
the top of the map window, consult the User’s Guide and Tools Guide included in
this package, as well as any management platform-specific documentation that
accompanied NetSight Element Manager.
Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows you how to contact the Enterasys Global
Call Center.

Introduction
1-2 Related Manuals
Chapter 2, The IRM2 Chassis View, describes the visual display of the
IRM2-controlled chassis and explains how to use the mouse within the Chassis
View; the operation of several chassis-level management functions — such as
changing the chassis display, naming boards, enabling and disabling boards and
ports, and setting device date and time — is also described here.
Chapter 3, Statistics, describes the Statistics, Timer Statistics, Summary Statistics,
and Performance Graph selections available at the repeater, board, and port
levels. Each of these selections provides a slightly different view of the network
information being collected by your IRM2.
Chapter 4, Source Address Functions, describes how to display the Source
Address lists, how to set the ageing time, andhow to locate the port being used by
a specific source address; it also discusses the effects of port locking.
Chapter 5, Alarm Limits, provides instructions on setting Alarm Limits for the
repeater, or for an individual board or port.
Chapter 6, Trap Selection, details how to use the Trap Selection window to
determine whether your IRM2 will send certain common SNMP traps to your
Enterasys management station.
Chapter 7, Redundancy, describes how to configure redundant circuits for your
IRM2 repeater, to ensure that vital network connections remain open and active.
We assume that you have a general working knowledge of Ethernet IEEE 802.3-
and FDDI-type data communications networks and their physical layer
components, and that you are familiar with general bridging concepts.

Software Conventions 1-3
Introduction
Software Conventions
NetSight Element Manager’s user interface contains a number of elements which
are common to most windows and which operate the same regardless of which
window they appear in. A brief description of some of the most common
elements appears below; note that the information provided here is not repeated
in the descriptions of specific windows and/or functions.
Using the Mouse
This document assumes you are using a Windows-compatible mouse with two
buttons; if you are using a three button mouse, you should ignore the operation of
the middle button when following procedures in this document. Procedures
within the NetSight Element Manager document set refer to these buttons as
follows:
Figure 1-1. Mouse Buttons
For many mouse operations, this document assumes that the left (primary) mouse
button is to be used, and references to activating a menu or button will not
include instructions about which mouse button to use.
However, in instances in which right (secondary) mouse button functionality is
available, instructions will explicitly refer to right mouse button usage. Also, in
situations where you may be switching between mouse buttons in the same area
or window, instructions may also explicitly refer to both left and right mouse
buttons.
Instructions to perform a mouse operation include the following terms:
•Pointing means to position the mouse cursor over an area without pressing
either mouse button.
•Clicking means to position the mouse pointer over the indicated target, then
press and release the appropriate mouse button. This is most commonly used
to select or activate objects, such as menus or buttons.
Left Mouse Button
Right Mouse Button

Introduction
1-4 Software Conventions
•Double-clicking means to position the mouse pointer over the indicated
target, then press and release the mouse button two times in rapid succession.
This is commonly used to activate an object’s default operation, such as
opening a window from an icon. Note that there is a distinction made between
“click twice” and “double-click,” since “click twice” implies a slower motion.
•Pressing means to position the mouse pointer over the indicated target, then
press and hold the mouse button until the described action is completed. It is
often a pre-cursor to Drag operations.
•Dragging means to move the mouse pointer across the screen while holding
the mouse button down. It is often used for drag-and-drop operations to copy
information from one window of the screen into another, and to highlight
editable text.
Common IRM2 Window Fields
Similar descriptive information is displayed in boxes at the top of most
device-specific windows in NetSight Element Manager, as illustrated in
Figure 1-2, below.
Figure 1-2. Sample Window Showing Informational Boxes
Device Name
Displays the user-defined name of the device. The device name can be changed
via the System Group window; see the Generic SNMP User’s Guide for details.
IP Address MAC
Address
Device
Name Location

Software Conventions 1-5
Introduction
IP Address
Displays the device’s IP (Internet Protocol) address. This will be the IP address
used to define the device icon. IP addresses are assigned via Local Management
for the IRM2; they cannot be changed via NetSight Element Manager.
Location
Displays the user-defined location of the device. The location is entered through
the System Group window; see the Generic SNMP User’s Guide for details.
MAC Address
Displays the manufacturer-set MAC address of the IRM2 with which NetSight
Element Manager is communicating. This address is factory-set and cannot be
altered.
Informational fields describing the boards and/or ports being modeled are also
displayed in most windows:
Board Number
Displays the number indicating the position of the monitored board in the chassis.
Board Name
Displays the user-entered name for the board. You can change the board name via
the Name option available from the Board menu.
Port Number
Displays the number of the monitored port.
Port Name
Displays the user-defined name of the port. You can change the port name via the
Name option available from the Port menu.
Active Users
Indicates the number of users processing information through the IRM2 repeater,
board, or port, as determined by MAC addresses.
Uptime
Displays the amount of time, in a days hh:mm:ss format, that the IRM2 has been
running since the last start-up.
Using Window Buttons
The button that appears at the bottom of most windows allows you to
exit a window and terminate any unsaved changes you have made. You may also
have to use this button to close a window after you have made any necessary
changes and set them by clicking on an , , or button.

Introduction
1-6 Getting Help
An , , or button appears in windows that have
configurable values; it allows you to confirm and SET changes you have made to
those values. In some windows, you may have to use this button to confirm each
individual set; in other windows, you can set several values at once and confirm
the sets with one click on the button.
The button brings up a Help text box with information specific to the
current window. For more information concerning Help buttons, see Getting
Help, page 1-6.
The command buttons, for example , call up a menu listing the windows,
screens, or commands available for that topic.
Any menu topic followed by... (three dots) — for exampleStatistics... — calls up a
window or screen associated with that topic.
Getting Help
This section describes two different methods of getting help for questions or
concerns you may have while using NetSight Element Manager.
Using On-line Help
You can use the IRM2 window buttons to obtain information specific to
the device. When you click on a Help button, a window will appear which
contains context-sensitive on-screen documentation that will assist you in the use
of the windows and their associated command and menu options. Note that if a
Help button is grayed out, on-line help has not yet been implemented for the
associated window.
From the Help menu accessed from the Chassis View window menu bar, you can
access on-line Help specific to the Chassis View window, as well as bring up the
Chassis Manager window for reference. Refer to Chapter 2 for information on the
Chassis View and Chassis Manager windows.
NOTE All of the online help windows use the standard Microsoft Windows help facility. If you
are unfamiliar with this feature of Windows, you can select Help from the menu,
or Help —>How to Use Help from the primary NetSight Element Manager window, or
consult your Microsoft Windows product User’s Guide.
