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 design ed 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 10/100BaseTX 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.
Chapter 1
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 ar e a ccessed dir ectly from the device
icon.
Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows yo u ho w to c o nt a c t t h e Gl ob a l 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 func tions — like enabling and disabling ports — is
also described here.
Chapter 3, FN100 V irtua l Switching, d escribes using the FN100 Virtual Switching
window to refine your network and control bandwidth usage by assigning the
FN100’s ports to any of four availa ble virtual switches.
1-1
Introduction
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 propa gated thr ough every bridge port o n your device.

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.
1-2 Related Manuals
Common FN10 0 Window Fields
Similar descriptive information is displayed in boxes at the top of most devicespecific windows in NetSight Element Manager, as illustrated in Figure 1-1.
Introduction
Device
Name
IP Address
Figure 1-1. Sample Window Showing Informational Text Boxes
Location
MAC
Address
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.
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.
Software Conventions 1-3
Introduction
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:
Left Mouse Button
Right Mouse Button
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 ) 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.
1-4 Software Conventions
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 b uttons.
• 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.
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 informat ion 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 wind ows,
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.

device. When you click on a Help button, a window will appear which contains
context-sensitive on-screen documentation that will ass ist you in the use of the
windows and their associated command and menu options. 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 on-line help windows use the standard Microsoft Windows help facility. If you

• ON if the port is actively forwarding and receiving packets.
• OFF if the port is not currently forwarding and receiving packets.
Load
If you choose L
oad, the interface text boxes will display the percentage of
network load processed by each port during the last polling interval. This
percentage reflects the network load generated per polling interval by devices
connected to the port compared to the theoretical maximum load (10 or 100
Mbits/sec) of an Ethernet network.
Errors
If you choose the E
rrors mode, the interface boxes will display the percentage of
the total number of valid packets processed by each port during the last polling
interval that were error packets. This percentage reflects the number of errors
generated during the last polling interval by devices connected to that port
compared to the total number of valid packets processed by the port.

The Chassis Manager Window
The FN100 draws its functionality from a collection of proprietary MIBs and IETF
RFCs, and organizes its MIB data into a series of components. A MIB component
is a logical grouping of MIB data; each group controls a defined set of objects. For
example, FN100 bridging information is organized into its own component. Note,
too, that there is no one-to-one correspondence between MIBs and MIB
components; a single MIB component might contain o bjects from several differ ent
proprietary MIBs and RFCs.
The Chassis Manager window, Figure 2-3, is a read-only window that displays the
MIBs and the MIB components — and, therefore, the functionality — supported
by the currently monitored device.

Raw Counts
The total count of network traffic received or transmitted on the indicated
interface since device counters were last reset. Raw counts are provided for the
following parameters:
In Octets Octets received on the interface, including framing
characters.
In Packets Packets (both unicast and non-unicast) received by the
device interface and delivered to a higher-layer protocol.
In Discards Packets received by the device interface that were
discarded even though no errors prevented them from
being delivered to a higher layer protocol (e.g., to free up
buffer space in the device).
In Errors Packets received by the device interface that contained
errors that prevented them from being delivered to a
higher-layer protocol.
In Unknown Packets received by the device interface that were
discarded because of an unknown or unsupported
protocol.
Out Octets Octets transmitted by the interface, including framing
characters.
Out Packets Packets transmitted, at the request of a higher level
protocol, by the device interface to a subnetwork address
(both unicast and non-unicas t ).
Out Discards Outbound packets that were discarded by the device
interface even though no errors were detected that
would prevent them from being transmitted. A possible
reason for discard would be to fr ee up buff er space in the
device.
Out Errors Outbound packets that could not be transmitted by the
device interface because they contained errors.
Load
The number of bytes processed by the indicated interface during the last poll
interval in comparison to the theoretical maximum load of the network to which
the device is connected (100 Mbps for Fast Ethernet). Load is further defined by
the following parameters:
In Octets The number of bytes received by this interface, expressed

You can also access this information via the I/F Statistics option available on the
individual port menus.
Three informational fields appear in the upper portion of the window:
Description
Displays the interface description for the currently selected interface: Ethernet or
Fast Ethernet.
Address
Displays the MAC (physical) address of the selected interface.
Type
Displays the interface type of the selected port: ethernet-csmacd.
The lower portion of the window provides the following transmit and receive
statistics; note that the first four statistics are also graphically displayed in the pie
charts.
Unicast
Displays the number of packets transmitted to or received from this interface tha t
had a single, unique destination address. These statistics are displayed in the pie
chart, color-coded green.
Non-Unicast
Displays the number of packets transmitted to or received from this interface tha t
had a destination address that is recognized by more than one device on the
network segment. The multicast field includes a count of broadcast packets —
those that are recognized by all devices on a segment. These statistics are
displayed in the pie chart, color-coded dark blue.
Discarded
Displays the number of packets which were discarded even though they
contained no errors that would prevent transmission. Good packets are typically
discarded to free up buffer space when the network becomes very busy; if this is
occurring routinely, it usually m eans that network traffic is overwhelming the
device. To solve this problem, you may need to re-configure your bridging
parameters, or perhaps re-configure your network to add additional bridges or
switches. These statistics are displayed in the pie chart, color-coded magenta.
Error
Displays the number of packets received or transmitted that contained errors.
These statistics are displayed in the pie chart, color-coded red.

Unknown Protocol
(Received only)
Displays the number of packets received which were discarded because they were
created under an unknown or unsupported protocol.
Packets Received

Displays the number of packets received by the selected interface.
Transmit Queue Size
(Transmit only)
Displays the number of packets currently queued for transmission from this
interface. The amount of device memory devoted to buffer space, and the traffic
level on the target network, determine how large the output packet queue can
grow before the FN100 will begin to discard packets.
Packets Transmitted

a MAC layer packet formation problem, or from a cabling problem that is
corrupting or losing data.
FCS
The number of frames received on a particular interface that are an integral
number of bytes in length, but do not pass the FCS (Frame Check Sequence)
check. FCS, or Frame Check Sequence, errors occur when packets are somehow
damaged on transit. When each packet is transmitted, the transmitting interface
computes a frame check sequence (FCS) value based on the co ntents of the packet,
and appends that value to the packet. The receiving interface performs the same
computation; if the FCS values differ, the packet is assumed to have been
corrupted and is counted as an FCS error.
SQE Test
Displays the number of times that the SQE Test Error message is generated by the
PLS sublayer on the selected interface. The SQE (Signal Quality Error) Test tests
the collision detect circuitry after each transmission. If the SQ E Test fails, a SQE
Test Error is sent to the interface to in dicate that the collision detect circuitry is
malfunctioning.
Transmission Errors
Carrier Sense
Displays the number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame on a particular interface. Carrier
sense describes the action an interface desiring to transmit will take to listen to the
communication channel to see if any other interface is transmitting. If a “carrier is
sensed,” the sensing interface will wait a random length of time, and then attempt
to transmit.
Frame Too Long
Displays the amount of frames received on this interface that exceed the
maximum permitted frame size.
Internal MAC
The number of frames that failed to be received by the interface due to an internal
MAC sublayer receive error. These errors are only counted if a Frame Too Long,
Alignment, or FCS Error did not occur along with the internal MAC error.
Receive Errors
Displays the total number of receive errors of all types that were detected by the
selected interface while it was receiving a transmission.
Deferred
Displays the number of frames for which the f irst transmission attempt on this
interface is delayed because the medium is busy.
2-20 Managing the Hub
Collision Errors
The FN100 Chassis View
Internal MAC
The number of frames for which transmission fails due to an internal MAC
sublayer transmit error. This error is only counted in this window if there have
not been corresponding Late Collisions, Excessive Collision s, or Ca rrier Sense
Errors.
Transmit Errors
The total of transmission errors of all types that occurred while the selected
interface was attempting to transmit frames.
Single
Displays the number of successfully transmit ted fra mes on the selected interface
for which transmission was prevented by one collision.
Multiple
Displays the number of successfully transmit ted fra mes on the selected interface
for which transmission was prevented by more than one collision.
Late
Displays the number of times that a collision has been detected on this interface
later than 51.2 microseconds into the transmission of the packet on a 10 Mbit/s
system or later than 5.12 microseconds on a 100 Mbit/s system.
Excessive
Displays the number of frames from this interface for which transmission was not
complete due to excessive collisions.
Collision Errors
Displays the total number of collision errors of all types tha t occurred during
transmission from this interface.
Enabling and Disabling Ports
From the Port menus on the FN100 Chassis View window, you can
administratively enable and disable the ports. When you administratively disable
a bridge port, you disconnect that port’s network from the bridge entirely. The
port does not forward any packets, nor does it participate in Spanning Tree
operations. Nodes connected to the network can still communicate with each
other, but they can’t communicate with the bridge or with other networks
connected to the bridge. When you enable a port, the port moves from the
Disabled state, through the Learning and Listening states, to the Forwarding
state; bridge port state color codes will change accordingly.

FN100 Virtual Switching
FN100 virtual switches; performing virtual switching
The FN100 Virtual Switching window (Figure 3-1) allows you to refine your
network and control bandwidth usage by assigning the FN100’s ports to any of
four available virtual switches. This feat ure can be used to logically group
network users and control the amount and type of traffic that is propagated
beyond each logical group.
Using this window, you can configure up to four logical segments that can
include multiple physical segments attached to the front panel ports (e.g.,
physical segments inserted in ports 1, 2, 5, and 8 could all be assigned to Switch 3,
and would communicate as if they actually w e re on the same physica l segment).
Using this capability , 10 and 100 Mbps devices can be placed on separate physical
segments, allowing the 100 Mbps devices to operate at full speed, and the switch
can treat both segments as a single logical net work.
Chapter 3
Each virtual switch is assigned a unique bridge ID and is treated as a separate
bridge by Spanning Tree. The bridge ID for each virtual switch is based on the
MAC address of the port in each group with the lowest index number.
The Default Switch setting determines which of the four available virtual switches
is queried for port-specific information for the Spanning Tree protocol. Because
each virtual switch is treated as a separate bridge by Spanning Tree, only ports
which are assigned to the Default Switch will be recognized by Spanning Tree and
correctly represented in the Bridge Status window.

2. Click Apply. The Virtual Switching window will update to reflect the new
configuration.
If you use the Virtual Switching window to assign por ts to a virt ual switc h other tha n the

Using FN100 Trunking
The Trunking Table window; enabling and disabling trunking
Trunking, an extension of the 802.1D Spanning Tree protocol, allows you to
increase aggregate bandwidth w hen two or m ore switches ar e con nected. A single
10/100BASE-T connection between switches yields 10 or 100 Mbps of bandwidth,
depending on the speed of the ports used for the connection. A trunk group is
created when two or more ports on the same switch (for which trunking protocol
is enabled) are physically connected to the same remote switch. By creating a
trunk group, each additional connection results in another 10 or 100 Mbps of
bandwidth, since the group of ports effectively acts as a single connection. The
trunking protocol modifies Spanning Tree to allow the redundant links which
form a trunk group. Trunking can be enabled or disabled for a port using the
Trunking Table window (Figure 4-1). Trunking can be enabled for use on up to
eight ports per switch, allowing you to configure up to four trunk groups
potentially yielding 80 or 800 Mbps of bandwidth, depending on the speed of the
interfaces.
Chapter 4
NOTE
!
CAUTION
Although you can enable trunking for more than eight ports on an FN100 (if more than
eight ports exist on your device), the trunking protocol prohibits the use of trunking on
more than eight ports at a time. If you enable trunking and establish a valid link for a
ninth port, the extra port will be in “hot standby” mode. If connections are broken for any
of the original eight trunk p o rts, the hot standby port wil l then participate in trunkin g,
provided that it has a valid link to a remote switch which is participating in a trunk
group.
You can add ports of different interface speeds to the same trunk groups; however, doing so
will cause the higher speed ports to assu me the same bandwidth as the lower speed ports,
so you effectively lose any t ransmission speed benefits for the faster port.

group. Ports in the same trunk group wi ll have the same remote bridge ID.
Rmt IP Address
Displays the remote bridge’s IP address.
Last Error
Displays a value (1-8) corresponding to a reason for failure when the link is in a
helddown state. These values and their corresponding reasons for fa ilure include:
• 1 — none — no error; the trunking protocol may restart with no error
conditions when trunking is activated for a port o r when the MIB variable that
controls extra trunk groups is modified.
• 2 — in-bpdu — a spanning tree BPDU was received, indicating that the
connection is not point-to-point, or that the far end of the link does not have
trunking enabled.
• 3 — multiple-bridges — a different bridge has been connected at the far end
of the link, and the trunking protocol will restart.
• 4 — ack-lost (acknowledgment lost) — the far end of the link has detected a
problem, and the trunking protocol will restart.

NOTE
The lower portion of the Port Trunking window displays the port selection area
which, when used in conjunction with the Enable and Disable buttons at the
bottom of the window, allows you to enable or disable trunking for selected ports.
The port selection area lists each of the FN100’s ports, their trunking state
(enabled or disabled), their MIB II ifIndex, ifType, and ifSpeed.
Trunking cannot be enabled f or the local management (ppp) port (port 9 or 17 , depending
on your FN100’s port configuration).
The Trunking Table window also features:
Clear
When the Clear button is clicked, any selections you have made in the port
selection area will be deselected.
Update
When the Update button is clicked, the FN100 will be queried for trunking
information, and any changes that have occurred since the window was opened
(or since the Update button was last clicked) will be reflected in the trunking
table.

Enabling and Disabling Trunking
To enable trunking for your FN100 ports using the Port Trunking window:
1. In the port selection list, click on an entry representing a port for which you
would like to enable trunking.
2. Click on Enable. The trunking table will update to include the new trunking
selection.
3. Repeat steps 1 and 2 for each port for which you want to enable trunking.
802.1D Spanning Tree takes about 30 seconds to resolve which FN100 ports in a
trunk group are to become forwarding ports. As ports within a trunk group
become forwarding ports, traffic within the trunk group will be momentarily
halted to guarantee the first-in, first-out ordering of Ethernet packets.
Connections between FN switches must be point-to-point; there cannot be any other
NOTE
devices on those segments. The FN100 ports used for trunking can be in any order.
Remember, though, that the switches on both ends of the connections must have trunking
enabled for their ports which are used for the connections.
Using FN100 Trunking
To disable trunking for your FN100 ports using the Port Trunking window:
1. In the port selection list, click on an entry representing a port for which you
would like to disable trunking.
2. Click on Disable. The trunking table will update to reflect the new trunking
selection.
3. Repeat steps 1 and 2 for each port for which you want to disable trunking.

Workgroup Configuration
Workgroups explained; adding and deleting workgroups from this window
The FN100’s Virtual Workgroups window allows you to restrict multicast traffic
from being propagated through every bridge port on your device. This optimizes
bandwidth by limiting the subnet broadcast traffic to only those ports that require
the traffic. You define a virtual work group by specifying a subset of device ports
and the type(s) of packets (multicast, unicast, or both) tha t are to be forwarded by
those ports. Each port can belong to more than one work group. In all, you can
create up to 100 virtual work groups per switch.
To access the Virtual Workgroups window from the FN100 Chassis View:

You can view and modify existing work groups as well as configure new work
groups from this window . The Workgroup Table at the top of the window lists
each existing work group along with its configuration informa tion. The
Add/Modify section of this window allows you to set-up the parameters of your
work group, including Name and Type. The Ports in Workgroup section of the
window allows you to choose the ports that will be included in the workgroup.
The IP Address, IP Mask, and IPX Ne twork fields in the Add/Modify section of the
NOTE
V irtual Workgr oups window are not applicable to the FN100 and ar e therefor e grayed out.
Though they may not appear this way upon opening the window, once you select a Type
of workgroup (see step #3 below), these fields will go gray.
Configuring a Workgroup
To add or modify a workgroup using the Virtual Workgroups window:
1. To modify an existing workgroup, click on the desired entry in the Workgroup
Table. The selected workgroup’s configuration information will be reflected in
the Add/Modify and Ports in Workgroup sections of the window.
2. Type a name in the Name field in the Add/Modify portion of this window. The
name can be 1-16 alphanumeric characters. You will use the name to identify
the workgroup.

Workgroup Configuration
3. Choose the Type of workgroup being created or modified. This determines
whether ports in this workgroup will forward only multicast packets, only
unicast packets, or both multicast and unicast packets. The following are your
possibilities:
• All — ports in this workgroup will forward both unicast and multicast
packets.
• Multicast — ports in this workgroup will forward only multicast packets.
• Unicast — ports in this workgroup will forward only unicast packets.
4. If necessary, use the Refresh button to deselect any ports you have
previously selected in the Port Selection area.
5. In the Ports In Workgroup area, click on the selection boxes corresponding
to the ports you would like to include in this workgroup. Each port is identified
by index number. Note that you cannot select the Network Management PPP
port for inclusion into a workgroup.
6. Click on Add if you are adding a new workgroup, or on Apply if you are
modifying an existing workgroup. New workgroup entries will be added to the
Workgroup Table, and changes to existing workgroups will be reflected in the
Workgroup Table.
7. Repeat steps 1-6 to add or modify any additional workgroups.
Deleting a Workgroup
In the Workgroup T a ble, h ighlight the work gr o up you would like to delete. Click
on Delete, the highlighted work group will be deleted. To have this change
reflected in the Workgroup Table, click on Refresh. The currently defined
workgroups will be displayed.
