Overview

Multi-channel Operation

By changing channels on adjacent access points, it is possible to
obtain higher throughput per wireless terminal than when is
channels are not changed, even when the number of wireless
terminals is increased.

The 2.4G ISH band (2400 to 2483.5 MHz) in which this product
operates is subdivided into 11 (FCC model) or 13 (CE model)
channels, numbered 1 to 11 or 13, by IEEE standard 802.11.
Because each frequency has sidebands around its central frequency,
sidebands on adjacent channels overlap. Overlapping frequencies
can adversely affect communications by interference with each
other's transmissions.

Refer to Figure 2.3 when selecting channels, to ensure that
frequency bands do not overlap.

The maximum number of channels that can be used simultaneously
without interference is four, by using a combination of channels 1, 6,

11. Channel numbers can be set from 1 to 11 using utility
software.

Two wireless terminals on the same network cannot use the same
frequency.

Figure 3.1. ADHOC Mode

In ADHOC (simple mode), all wireless devices are paired, and can
use wireless communication with the other device in the pair.
Lines can be duplicated using a spanning tree if bridges are
constructed using AP connections.

- Advantages
(1) Requires virtually no setup work to start.
(2) Can bridge multiple wired LAN's, allows duplication of lines.

- Disadvantages

Note!

(1) When the AP is a relay point the available communication

range is narrower than in infrastructure mode.

(2) Not suited to construction of large wireless LAN environments.

When configuring a wireless LAN in simple (ADHOC) mode, be
sure to place all wireless terminals within effective communication
range. If units are too far apart, communications can be hindered
by partitions or other obstacles causing some terminals to be
unreachable and reducing system throughput.

FX-DS110-APL 13

Operating Mode Descriptions

Infrastructure (Standard Mode / Compatible Mode)

This mode allows the use of multiple AP's to configure wide-area
wireless LAN's. All communication between wireless terminals
must go through an AP.

Figure 3.2. Infrastructure Mode

Note!

Roaming functions are supported, allowing log-in on any unit
type AP.

- Advantages
(1) Allows multiple AP's to be set up to configure wide-are

wireless LAN's.

(2) Allows log-in restrictions on unit type AP's (security function).

- Disadvantages
(1) All AP's must be IP controlled, requiring many settings.

When set as a station in Infrastructure (Compatible Mode), only
one PC can be connected via Ethernet.

Spanning Tree Algorithms (STA)

6. Spanning Tree Algorithms (STA)

This chapter describes spanning tree algorithms (STA's) supported
by this product.

What is an STA?

Communication between nodes on two bridged LAN segments
must take place on one path. If two or more paths exist, packets
may get caught in the loop and the network, unable to eliminate the
packets, may crash. If the network can be configured in such a
way as to eliminate the possibility of network loops this problem
cannot occur, but if spare paths are provided and used, it is
necessary to switch routes manually. The problem can be avoided
if the bridge has the following functions.

Network Loop Detection and Avoidance

This function detects path that are involved in network loops and
keeps only one path active. The other path is kept available for
backup but cannot be used.

Automatic Topology Reconfiguration

This function reconfigures the network topology when a fault
occurs on a backup route.

Note!

This method of resolving problems is called an STA, and has been
standardized by the spanning tree protocol (STP) established in
IEEE 802.1D. STP can enhance network reliability.

For STA's to function properly, all bridges in a network must
support STP.

FX-DS110-APL 43

Spanning Tree Algorithms (STA)

STA Parameters

STA's function on two levels, bridge level and port level. Multiple
timers are used to periodically check the proper operation of bridges
and ports. The following section describes the parameters and
terms used in this product.

Bridge Level

Root Bridge

First, the bridge is determined using the bridge identifier (bridge
priority level and Ethernet address) of the bridge. The bridge
identifier of the root bridge is the smallest.

If more than one bridge exists with the same priority level, the root
bridge is determined by Ethernet address.

Designated Bridges

In each LAN segment, the bridge having the lowest root path cost
to the root bridge is the designated bridge. The designated bridge
serves to carry the packages of that LAN segment.

If more than one bridge is connected to the same LAN segment, and
the root path costs are exactly the same, the bridge with the smallest
bridge identifier becomes the designated bridge.

Bridge Priority

The priority level can be set in the range 0 to 65535. The smaller
this number, the higher the priority. If priorities are changed, all
bridges and root bridges in the network will be re-determined.

Root Path Cost

The total path cost from the designated bridge to the root bridge is
the root path cost. The root path cost of the root bridge is zero.

BPDU Effective Time (Max Age Time)

Set in the range from 6 to 40 (seconds). If the bridge does not
receive a packet notifying the existence of a root bridge within this
time, the system assumes there is a failure in the root bridge, and
determines a new root bridge.

FX-DS110-APL44

Note!

Spanning Tree Algorithms (STA)

BPDU Send Interval (Hello Time)

Set in the range from 1 to 10 (seconds). This determines the
interval within which a bridge that is the root bridge sends a packet
notifying its existence. This parameter may not exceed the Max
Age Time.

Forward Delay Time

Set in the range 4 to 30 (seconds). When the ports of a bridge
change from blocking to forwarding status, this determines the time
in which they will remain in listening status.

The following conditions must be observed when making changes to
the above time settings.

FX-DS110-APL 45

Spanning Tree Algorithms (STA)

Port Level

Root Port

On each bridge, the port having the lowest path cost to the root
bridge is called the root port.

If more than one port has the same path cost, the port with the
smallest port identifier (port priority and assigned port ID) is the
root port.

Designated Port

The port on the designated bridge connected to the LAN segment is
called the designated port.

On the bridge, packages are only transferred on the port that is the
root port, and other ports are blocked.

Port Priority

Set in the range 0 to 255. The lower the number, the higher the
priority level.

Path Cost

The port cost on a path is called the path cost, and is set as follows
when this product is initialized. This value is based on IEEE
standard 802.1D, but can be changed.

8. Troubleshooting

This chapter describes common problems that may occur with this
product and what to do about them. If any problems occur that are
not described here, check to confirm that the re-occur, then contact
the store where you purchased the product, or the CONTEC
information center.

When Communication Fails

Check hardware

- Check that the LAN cables are connected correctly.

Check software

- The FLEXLAN-DS110 series is designed to handle a variety of

operating formats, and requires software setting for each type of
operation. Check that the settings are appropriate for the type of
operation, and check the format in which communication is being
attempted. Also check DIP switch settings.

- The terminals that cannot communicate with each other may have

the same ESS ID. Two terminals with the same ESS ID cannot
communicate with each other.

- Check that the APL IP address and subnet settings have been

entered.

- Check that the operating mode setting has been correctly entered.

- Check whether communication is restricted by security functions.

- Check whether the data encryption setting is the same as that of

the recipient.

- Check that the channel setting has been correctly entered.

- Check that the communication speed setting has been correctly

entered.

Troubleshooting

FX-DS110-APL 55

Troubleshooting

Check the peripheral environment and place of installation

- A nearby source of electromagnetic interference can prevent

Most electromagnetic sources other than wireless networks are local
and not continuous, and therefore by moving the location of the unit
and waiting briefly, communication may be possible.

Also, do not place wireless devices too close together. A distance
of at least 1m should be allowed.

- Sometimes communication is hindered by attenuation of electric

communication. In general locations (excluding factories) the
following may be sources of electromagnetic emissions.

- 2.4GHz band wireless networks not compatible with IEEE

802.11b.

- Microwave ovens

- Security gates

- Copiers

- Elevator motors

waves. Attenuation occurs naturally as distance from the source
of transmission increases, but may also be caused by objects in
the path of the transmission. The objects primarily responsible
for attenuation are the following.

- Concrete walls

- Metallic surfaces around antennas

Stable transmission at 11Mbps requires an RSSI value of at least 80.
The RSSI value can be verified on the Wireless Device Information
tab on the Status screen using the utility software.

When SNMP Connections Fail

- It is possible that the device cannot locate a control parameter, or

that a private MIB has not been compiled. See Chapter 6.

- If MIB settings have not been made, the correct community name

may not have been entered. Be sure the community name
setting agrees with the network manager's setting.

- Check the SNMP settings that are being used.

When the APL Will Not Start

Check the power LED

- Be sure the power LED is on. If it is not on, check the AC

adapter, be sure it is correctly plugged into an outlet, and that the
power supply type agrees with the power supply switch setting.

- Check whether the power LED is flashing. If the power LED is

still flashing more than 10 minutes after the power is switched on,
the problem may be an APL firmware failure. Use the utility
software to upgrade the firmware version.

Glossary

IEEE (Institute of Electrical Electronics Engineers)

"I-triple-E," involved in a wide range of fields from
communications and computer to medicine and biology, with
primary activities related to publishing articles and sponsoring
conferences, but also recommending and setting of standards. The
organization sponsoring Committee 802, which is responsible for
LAN related matters.

IEEE 802.11/ IEEE 802.11b

The wireless LAN standard established by the IEEE.

MIB (Management Information Base)

The value of a MIB is determined by the Internet standard control
information structure.

SNMP (Simple Network Management Protocol)

A function necessary for network control, provides three functions:
Get (acquire), Set (modify), and Trap (notify event). Conceived as
an easily installable control protocol that places as little load on the
network as possible.

Diversity

A method of using multiple antennas, and selecting the one with the
best receiving conditions.

Router

A device for relaying between LAN's. The router determines data
addresses by the combination of a network address assigned to the
network and an individual computer address. Used particularly in
medium-scale and larter LAN systems with very large number of
clients, to reduce traffic (congestion) on communication lines.

Bridge

A device for relaying between LAN's. The bridge determines
whether to relay data based on the address of the computer to which
the data is being sent. It can be used to connect networks having
different protocols, or when data for broadcast to all computers is
received, can send this to all connected networks.

FX-DS110-APL62

Appendix

LAN (Local Area Network)

A network configured from mutual connections between computers
within a limited area. Also called an "intranet" or "business or
regional data communications network."

RSSI (Receive Signal Strength Indication)

A numeric indicator of incoming signal strength.

Spectrum diffusion transmission

A method of transmission in which signals that are normally
transmitted over a given limited frequency band undergo narrow
band modulation (primary modulation), then again diffuse
modulation (secondary modulation) to intentionally diffuse the
signal over a broad frequency spectrum.

DS (Direct Sequence)

A type of spectrum diffusion signal using narrow band modulation
with phase modulation, in which the diffusion is by means of phase
modulation using a broad band diffusion signal (pseudo random
strings).

CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance)

CSMA is a method of avoiding collision by which wireless
terminals listen before transmitting and do not transmit if they can
year transmissions from other wireless terminals. CSMA/CA is
CSMA plus additional collision avoidance functions.

Hidden Terminal Problem

When wireless terminals are farther apart then their electric signals
can reach, or their signals are obstructed by objects, neither may be
able to receive the other's signals. Any two such wireless
terminals are said to be hidden from each other. In Ad Hoc mode,
because the carrier sense function is not effective between hidden
terminals there is a higher probability of collisions and throughput
(the volume of information sent in a given time interval) is reduced.

FX-DS110-APL 63

Appendix

RTS (Request to Send)

In communication via AP, transmission is controlled by CSMA/CA
plus RTS. In RTS, a wireless terminal asks the AP if it is all right to
transmit, and only transmits after an OK-to-send acknowledgement
signal is returned. This serves to avoid unnecessary collisions when
hidden terminals exist because hidden terminals cannot transmit.

Roaming

This term has the same meaning as roaming for a portable phone or
PHS. The AP is in the role commonly called the 'antenna/base
station' for the phone or PHS, and the user unit is in the role of the
phone itself.

Peer-To-Peer

A network in which two or more nodes can communicate directly
with each other without going through another device.

AP (Access Point)

In the FLEXLAN-DS110 series, access points serve as the bridge
between wired networks and wireless networks, as well as providing
bridge functions between segments and IP tunnel functions
indispensable to the building of versatile, large-scale networks.

User Unit

In the FLEXLAN-DS110 series, this refers to the FX-DS110-PCC
or a device with the FX-DS110-PCC built in.

ESS ID (Extended Service Set ID)

In the FLEXLAN DS110 series, the ESS ID is like a name assigned to
the wireless LAN network to which a unit belongs. The same name
must not be given to more than one wireless terminal. Conversely, a
wireless network can be partitioned by using different ESS ID names.

Channel

This term has the same meaning as a television or radio channel.
In the 2.400 to 2483.5GHz ISM band used by this product, the
IEEE 802.11 standard provides for division into 11 (FCC model) or
13 (CE model) channels numbered 1 to 11 or 13. Even on the
same network, wireless devices operating on different channels
cannot communicate with each other.
