Introduction
How to use this guide; related guides; software conventions; getting help; MicroMMAC-T firmware
versions
Welcome to the NetSight Element Manager for the MicroMMAC-T User’s Guide.
We have designed this guide to serve as a simple reference for using NetSight
Element Manager for the MicroMMAC-22T/24T and MicroMMAC-42T/44T.
The MicroMMAC-22T/24T™and MicroMMAC-42T/44T™are intelligent Token
Ring hubs that provide front panel ports for network connections, a rear-panel
HubSTACK™Interconnect Bus port for stackable connections, and a rear-panel
port for one optional Bridge Router Interface Module™(BRIM®) that provides the
MicroMMAC-T™with bridging and routing capability. All the devices fully
conform to the IEEE 802.5 standards, and provide the flexibility to connect
networks using a variety of media via 12 or 24 active RJ45 ports for STP or UTP
lobe connections. All of the models are functionally identical; the only difference
among them is the configuration of the front panel ports: the MicroMMAC-22T
has 12 built-in active UTP RJ45 lobe ports; the MicroMMAC-24T has 24 built-in
active UTP RJ45 lobe ports; the MicroMMAC-42T has 12 built-in active STP RJ45
lobe ports; and the MicroMMAC-44T has 24 built-in active STP RJ45 lobe ports.
Using the MicroMMAC-T’s external HubSTACK-IN and HubSTACK-OUT
connections on the rear of the unit, you can stack as many as four of Cabletron’s
STH Series non-intelligent Token Ring hubs with one MicroMMAC-T, and the
entire stack can be managed by the MicroMMAC-T as a single Token Ring. This
configuration allows you to expand the connectivity of the MicroMMAC-T to up
to 120 ports.
NOTE Since the devices covered in this User’s Guide are functionally identical, they will be
jointly referred to throughout the text as the MicroMMAC-T. Likewise, since the only
differences in the windows for each device will be the device name (MicroMMAC-24T,
MicroMMAC-44T, etc.) and the number of ports displayed, only the MicroMMAC-24T
windows will be shown.

Introduction
1-2 Using This Guide
NetSight Element Manager provides remote management for the MicroMMAC-T,
including:
• Front panel status display with administrative state, network load, and error
percentages available for each port.
• Management Station Configuration.
• Station List and Map Windows.
• Full statistics display for the hub and individual stations (with both numerical
and graphical display options).
• Alarm Limits based on frame counts, frame errors, or beacon frames.
You should read this manual thoroughly to understand NetSight Element
Manager for the MicroMMAC-T.
Using This Guide
Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the MicroMMAC-T device module. This guide
contains information about software functions that are accessed directly from the
device icon; for information about management functions that are accessed via
the NetSight Element Manager platform, consult the NetSight Element Manager
User’s Guide and NetSight Element Manager Tools Guide.
Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows you how to contact the Enterasys
Networks Global Call Center.
Chapter 2, The MicroMMAC-T Chassis View, describes the visual display of the
MicroMMAC-T’s front panel and explains how to use the mouse within the
Chassis View; the operation of several chassis-level management functions —
such as changing the port status display, enabling and disabling ports,
configuring the management station, and setting device date and time — is also
described here.
Chapter 3, Token Ring Statistics, describes the Statistics, Timer Statistics,
Summary Statistics, and Performance Graph selections available at the Network,
Management Station, and Port levels. Each of these selections provides a slightly
different view of the network information being collected by the MicroMMAC-T.
Chapter 4, Token Ring Alarms, provides instructions on configuring and setting
ring-level alarms for network events, ring-level station alarms that apply to all
stations on a ring, or station-level alarms for individual stations on a ring.
Chapter 5, The Station List and Station Map, describes how to use these
windows to view your ring topology, either in list or graphical (map) format, and
how to access statistics and set alarm limits for your ring stations.

Introduction
We assume that you have a general working knowledge of Token Ring IEEE 802.5
type data communications networks and their physical layer components.
Related Manuals
The MicroMMAC-T user’s guide is only part of a complete document set
designed to provide comprehensive information about the features available to
you through NetSight Element Manager. Other guides that include important
information related to managing the MicroMMAC-T include:

Software Conventions
NetSight Element Manager’s device user interface contains a number of elements
that are common to most windows and that 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
1-4 Software Conventions
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.
•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.

Software Conventions 1-5
Introduction
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.
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 1-7.
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.
Common MicroMMAC-T 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.
