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 IR M2
User’s Guide. W e have designed this guide to serve as a simple refer ence 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
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 ar e a ccessed dir ectly 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.

1-1
Introduction
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, and how 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 802.3­and FDDI-type data communications networks and their physical layer components, and that you are familiar with general bridging concepts.

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:
Introduction
Left Mouse Button
Right Mouse Button
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 ) m ouse button functionality is
available, instructions will explic itly refer to right mouse button usage. Also, in
situations where you may be switching between mouse buttons in the same area
or window, instru ctions 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 b uttons.
Software Conventions 1-3
Introduction
• 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 de scribed 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.
Device Name
IP Address
Figure 1-2. Sample Window Showing Informat ional Boxes
Device Name
Displays the user-defined name of the device. The device name can be changed via the System Group window; see the Gener ic SNMP User’s Guide for details.
Location
MAC Address
1-4 Software Conventions
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 manufact u rer-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 boar d 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 m enu.
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.
Software Conventions 1-5
Introduction
An , , or button appears in win d ows 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 example Statistics... — 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 NetS ight 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.
All of the online help windows use the standard Microsoft Windows help facility. If you

MIM Port Status Displays

When you open the Chassis View window, each port on the IRM2 and the associated MIMs installed in the hub will display its Admin/Link status (defined below); to change this status display, select one of the options on the Port Status menu, as described in the following sections.
Selecting a Port Status View
To change the status view of your ports:
1. Click on P a menu will appear.
2. Drag down (and to the right, if necessary) to select the status information you want to display. The port text boxes will display the appropriate status information.
Port status view options are:
Load
If you choose L load processed by each port during the last polling interval. This percentage reflects the network load generated by devices con nected to th e po rt compared to the theoretical maximum load (10 Mbits/sec) of an Ethernet network.

NOTE
The IRM2 Chassis View
In NetSight Element Manager, the polling interval is set via the Tools—>Options window available from the primary window menu bar.
Refer to the NetSight Element Manager User’s Guide for full information on setting device polling intervals.
Port Type
If you choose Port T
ype, each port status box will display that port’s topology
status: station or trunk. A station port (displayed as STA) is one which has zero or one source addresses in its source address table; a trunk port (designated TRK) has two or more source addresses in its table. If a board does not support the Port Type option, its port status boxes will remain blank. For more information about the source address table, see Chapter 4, Source Address Functions.
Status
You can view three status categories for your ports, which reflect six possible Admin/Link, Admin, or Link status conditions:
• Admin/Link — ON, OFF, SEG (segmented), or NLK (not linked)
• Admin — ON or OFF
• Link — LNK (link), NLK (not linked), or N/A (not available) If you have selected the A
dmin/Link status mode, a port is considered:
• ON if the port is enabled and has a valid link.
• OFF if it has not been enabled or if it has been disabled through management
action.
SEG (segmented) if the port has been enabled by management and has a valid connection, but has been segmented by the repeater because 33 consecutive collisions have occurred on the attached segment, or the collision detector was on for more than 2.4 µs.
