Introduction
How to use this guide; related guides; software conventions; getting help
Welcome to the FN100™ User’s Guide. We have designed this guide to serve as a
simple reference for using NetSight Element Manager for the FN100.
As a part of the Fast Network product line of switches, the FN100 provides a
foundation for high speed scalable Ethernet switching solutions. The FN100 is a
high performance, intelligent Fast Ethernet switch designed to support full 10
Mbps or 100 Mbps connectivity on 8 or 16 ports over unshielded twisted-pair
(UTP) and/or multimode (MM) fiber. The FN100 consists of 8 or 16 10/100Base-
TX or 10/100Base FX ports and, in the case of the TX models, 1 or 2 selectable
100Base-FX ports. The FN100 is IEEE 802.2, 802.3 and 802.1d compliant, includes
built-in SNMP management, and supports MIB II, PPP, and Enterprise MIB.
Using the FN100 User’s Guide
Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the FN100 device module. This guide contains
information about software functions which are accessed directly from the device
icon.
Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows you how to contact the Global Technical
Assistance Center.
Chapter 2, The FN100 Chassis View, describes the visual display of the FN100-
switch and explains how to use the mouse within the Chassis View; the operation
of chassis-level management functions — like enabling and disabling ports — is
also described here.
Chapter 3, FN100 Virtual Switching, describes using the FN100 Virtual Switching
window to refine your network and control bandwidth usage by assigning the
FN100’s ports to any of four available virtual switches.

Introduction
1-2 Related Manuals
Chapter 4, Using FN100 Trunking, details using the FN100 Port Trunking
window to create trunk groups, allowing you to increase aggregate bandwidth
when two or more switches are connected.
Chapter 5, Workgroup Configuration, describes configuring work groups by
specifying a subset of device ports and the type(s) of packets (multicast, unicast,
or both) that are to be forwarded by those ports, thereby allowing you to restrict
multicast traffic from being propagated through every bridge port on your device.
Related Manuals
The FN100 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 which include important information
related to managing the FN100 include:

Tools Guide
Remote Administration Tools User’s Guide
Remote Monitoring (RMON) User’s Guide
Alarm and Event Handling User’s Guide
For more information about the capabilities of the FN100, consult the appropriate
hardware documentation.
Software Conventions
NetSight Element Manager’s device 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.

Software Conventions 1-3
Introduction
Common FN100 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 1-1.
Figure 1-1. Sample Window Showing Informational Text 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
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 FN100; 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.
IP Address MAC
Address
Device
Name Location

Introduction
1-4 Software Conventions
MAC Address
Displays the manufacturer-set MAC address associated with the IP Address used
to define the device icon when it was added to NetSight Element Manager. 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:
Port Number
Displays the number of the monitored port.
Uptime
Displays the amount of time, in a X days hh:mm:ss format, that the FN100 has
been running since the last start-up.
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 1-2. 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.
Left Mouse Button
Right Mouse Button

Software Conventions 1-5
Introduction
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.
Using Window Buttons
The Cancel 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 OK, Set, or Apply button.
An OK, Set, or Apply 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 Help 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 Bridge, 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.
