This chapter explains what the 0100 Access Point is and how it fits into your network

This is for the graphics

operating system.

Introduction

The 0100 Access Point acts as a wireless bridge for JANUS RF readers and other
wireless LAN products that run in the 2.4 GHz network to communicate with
your Ethernet network. It allows easy expandability of your wireless network
by increasing range and facilitating mobile applications. It operates at the Data
Link level (layer 2) of the OSI model, providing protocol-independent access for
JANUS reader users in an existing IEEE 802.3 wired Ethernet LAN. See the
Appendix for a diagram of how the Access Point fits into the OSI model.

The Access Point is designed as a “plug-and-play” product. In many cases, you
will not even need to configure it. If you need to use the configuration software,
it is simple to understand and has online help.

Network operating systems can be broken into three functions:

• The server is the core of the network operating system and provides
memory management, the network filing system, and task scheduling.

• Network applications provide the functions of the network, such as e-mail
and database capabilities.

• The client (workstation) provides the ability for the user to attach to the
network and access the client-server applications or server functions.

A Moderately Complex Network With Two RF Subnetworks

In a moderately complex network, you may need the additional capabilities of
multiple Access Points:

• Transparent bridging, which supports all protocols.

• Spanning tree protocol support (IEEE 802.1d), which supports the IEEE
standard for interoperability and dynamically reconfigures the network if a
link is broken or if you add products.

• Simple Network Management Protocol (SNMP) capability, which can be
managed by an SNMP management package.

If you want to establish two independent RF subnetworks, you can use
different channels and domain numbers to isolate the subnetworks. Only
adapters with the same domain can establish communications.

Roaming

With the Access Point’s roaming capability, you can break the wireless distance
barrier by installing them throughout your building. The Access Points act as
“cells,” similar in concept to those of a cellular phone network. Make sure that
the coverage of each Access Point overlaps to provide uninterrupted wireless
access at any location within the building.

Note: The cells must overlap to ensure that there are no gaps in coverage and that the
roaming JANUS reader will always have a connection available.

In a roaming network, you should configure each Access Point for a different
channel/subchannel pair, but you must configure each one with the same
domain number and security ID. You must also configure the JANUS readers
with the same domain. These configurations ensure that the JANUS readers can
switch from Access Point to Access Point while preserving wireless
connectivity. When the roaming JANUS reader leaves the transmission range of
one Access Point, the software automatically polls the other Access Points in the
same domain to continue the network connection.

Note: Roaming stations will only roam among Access Points with the same domain
and security ID.

The following illustration displays an example of a moderately complex
network that has been set up with a roaming domain.

About Peer-to-Peer Network Operating Systems

This is for the graphics

Today’s network operating systems can support multiple servers and hundreds
of workstations in the same LAN environment. Since, these server-based
network operating systems are often too sophisticated and expensive for the
needs of the small office or work group, a variety of companies developed
peer-to-peer network operating systems. These new products offer affordable
prices, easy installation and operation, and flexibility for future growth.

A Peer-to-Peer Network Operating System

INTERMEC

With a peer-to-peer NOS, each PC can be configured as a client, a server, or
both. Peer-to-peer means that each PC can share all of its resources, such as
files or printers, with any other PC on the network. This type of network
operating system differs from traditional network operating systems where
one product, a dedicated server, is required for sharing resources. Client PCs,
using traditional network operating systems, cannot share data with other
clients without storing the information on a server.

Configuring the Access Point Remotely

To configure the Access Point remotely, you need:

• a DOS-based PC with an Ethernet card

To configure the Access Point

1. Load a packet driver for your Ethernet card on your PC. If you wish to use
the Ethernet card’s ODI driver rather than a packet driver, follow Step 2
through Step 5. Otherwise, go to Step 6.

2. Copy the ODI driver for this card into the same directory on your PC as the
configuration application.

3. Edit the NET.CFG file (using a text editor like MS-DOS Edlin or Edit) and
add the following information:

LINK SUPPORT
BUFFERS 6 1600

For an example of the NET.CFG file, refer to Appendix A.

4. In the NET.CFG file, under the Link Driver section for your Ethernet card,
make sure that the following line is listed as the first frame type:

3-6

FRAME ETHERNET_II

For an example of the NET.CFG file, refer to Appendix A.

5. Edit your AUTOEXEC.BAT file to load LSL, the ODI driver, and ODIPKT
(using a text editor like MS-DOS Edlin or Edit).

For an example of the AUTOEXEC.BAT file, refer to Appendix A.

6. Edit the CFG.CFG file to add the IP address for the PC that is running the
configuration application (using a text editor like MS-DOS Edlin or Edit).

If your network does not carry IP traffic, use the default setting of 192.0.1.1.
The network portion of the PC’s IP address must match that of the IP
address of the Access Point.

An example of the CFG.CFG file is as follows:

# Configuration Tool configuration file
ip_address 192.9.200.24

entries for those stacks in the NET.CFG file and bind them to the proper frame type.

Configuring the Access Point Using SNMP Management
Packages

You can manage the Access Point using any SNMP management package. The
Access Point supports the following managed objects:

• MIB-II (RFC 1213)

• IEEE 802.1d Bridge MIB (RFC 1493)

• Enterprise MIB - The Enterprise MIB is supplied in ASN.1 format on the
Access Point diskette. Follow the instructions in your SNMP management
package for incorporating enterprise-specific MIBs.

More About the Access Point Filters

The filter configuration allows you to customize the type of traffic that is
forwarded from the Ethernet network to the RF network. If one of the boxes
contains a check, this indicates that traffic that meets the corresponding filter
characteristic such as the Protocol Type will be filtered out and will not be
forwarded.

Non-2.4 GHz RF Address Filter This filter prevents traffic that is destined to a
non-broadcast, non-multicast, non-RF address from being forwarded from
Ethernet to wireless.

Do not use this filter when using the node address overwrite feature on RF
stations.

Novell IPX Broadcast Filters These filters prevent IPX broadcasts of the
specified types from being forwarded from Ethernet to RF. Since RIP, SAP,
and LSP broadcasts are of interest to routers and not end stations, these filters
can typically be turned on.

Protocol Type Filters These filters prevent traffic of a particular protocol type
from being forwarded from Ethernet to RF. When “Other Types” is checked,
all types other than those listed will be filtered out.

Do not filter out the types of packets you know RF nodes will need to receive.
If you use TCP/IP as a protocol on your network, do not filter IP/ARP traffic.
If you have Macintosh computers on your Ethernet network that send

AppleTalk traffic only to each other, you may want to filter those packets from
RF stations.

3-16

ARP Filter This filter enables IP ARP broadcast filtering. When this filter is

enabled, ARP broadcasts will be forwarded from Ethernet to RF only if the
destination IP address is on the IP network defined by the IP Network
Address and Subnet Mask fields.

Helpful Hints

The following sections provide some helpful hints that may make your Access
Point or your network run more efficiently.

Running Large Executable Files Efficiently

Some executable files, like Novell’s LOGIN program, can take a long time to
start up. You may be able to reduce this time if you copy the file to your local
hard disk. This way the server is only accessed to read data files, which will
allow for better performance.

Novell’s VLM Technology

The ISA and PCMCIA ODI drivers support Novell’s new VLM technology. It is
the new standard interface for NetWare 2.x, 3.x, 4.x, and Personal NetWare
clients. If you choose to use VLM.EXE instead of NETX.EXE when attaching a
NetWare 2.x, 3.x, 4.x, or Personal NetWare client, you will achieve greater
performance by up to 82% according to Novell’s Systems Research Department
tests. On a NetWare 3.11 server, you must load PBURST.NLM for the VLM
technology’s performance enhancements to take effect.

Determining Master Stations and Alternate Master
Stations

The 2.4 GHz RF network uses a spread spectrum frequency hopping technique.
This technique means that the radio signal is constantly moving from one
frequency to another in a predefined sequence. In order for several radios to
communicate, they must be at the same frequency at the same time.

The master station sets the pace for the other radios. All stations look to the
master station to determine where and when to hop. If no master station is
present, a station configured as an alternate master station will become the
master for that session.

4-3

This configuration leaves the system administrator for the network with the

alternate master station, or a station. In most cases, using the default
configurations for each of the drivers will work fine. There may be times,
however, when an administrator wants to change the configuration for
performance or for other reasons.

Here are several factors to consider:

1. In every wireless network, at most one station must act as the master
station. If you need to set up additional master stations, they should be
configured as alternate master stations so that there is only one true master
station on the network.

2. The master station must be within range of the other wireless stations on
the network.

3. The master station should not be a station that will be moved or turned off
like a notebook computer or a user’s personal machine.

4. On a client-server based network, it usually makes sense for the server to
be the master station.

5. On a peer-to-peer based network, it is probably a good idea to designate at
least one computer as an alternate master station in the event that the
master station is unavailable.

4-4

6. On a network with all notebook or pen-based computers, it may be
advisable for all machines to be alternate master stations.

7. You will achieve better performance by configuring the fewest number of
machines possible as masters or alternate masters.

Microwave Ovens

Microwave ovens operate in the same frequency band as the 0100 Access
Point. Therefore, if you use a microwave within range of the 0100 you may
notice network performance degradation. However, both your microwave and
your 0100 network will continue to function.

Antenna Placement

Proper antenna placement can help improve Access Point performance. Use the
following guidelines:

• Place the antenna as high as possible in an office environment above cubicle
walls.

• Do not place a sheet of metal between two antennas.

• Make sure that the two antennas that are communicating are in the same
plane. For example, do not lie one antenna on its side and have its partner
standing upright.

• If the Access Point is mounted towards the ceiling, do not put the antenna on
top of it.

Troubleshooting

The Access Point is very easy to install and operate. If you do experience
difficulties however, use the information in this section to help diagnose and
solve the problem. If you cannot resolve the problem, contact your Intermec
service representative.

Problem: No response from the Access Point when configuring

How the 2.4 GHz RF Network Fits in the OSI Model

This is for the graphics

In 1977, a joint international working group, ISO/CCITT (International
Standards Organization/Comité Consultatif Internationale de Telegrafique et
Telefonique) developed the OSI reference model as a basic framework to deal
with the complexity of communicating systems and the required protocol
standards.

The OSI model divides a network into seven layers, each with clear tasks or
functions. It also provides specific input to adjacent layers. Both hardware and
software functions are accounted for in the model.

Understanding the Radio Parameters

Access Points easily integrate into your existing network operating
system. Each client on your network operates the same as any wired
client PC except that wireless units share the same media or airspace.
The following RF parameters allow the wireless adapters to share the
same airspace effectively.

Note: Do not assign two Access Points or ISA cards to the same domain,
channel, and subchannel unless you are purposely doing this in a spanning
tree. If two wireless adapters have these parameters the same, you will create a
loop in the network.

Station Type

Master Alternate Station

210

Appendix B

B

You need to configure each wireless adapter as a master, alternate
master, or station. In each subnetwork, one master coordinates
communication between various stations. This acting master can be
either a master or an alternate master. An alternate master acts as
either a master or a station. If an alternate master locates a master, then
it acts as a station. If an alternate master cannot locate any other master
within range, it acts as a master. For most network operating systems,
define the ISA card in the server or Access Point as the master and all
clients such as JANUS readers as stations.

A setting of 0 indicates the unit is a station; 1 indicates alternate master;
2 indicates master. The Access Point defaults to a station type of 2.

For performance considerations regarding the setting of this
parameter, refer to Chapter 4, “Helpful Hints and Troubleshooting.”

X X N/A

Each master can select one of 15 channels to establish communications with
stations. The channels are designated 1 through 15, with 1 being the default
setting. Wireless products use the surrounding air as the medium to transmit
information. Each channel separates communications for each subnetwork to
allow for higher data rate transmission capability in the same airspace. Each
channel provides the 1.6 Mbps for a maximum total bandwidth of 24 Mbps in a
particular area.

B-4

For networks with multiple masters, set each master to a different channel for
optimum performance.

Subchannel

Master Alternate Station

X X N/A

If you need more than 15 masters in the same area, you can change the
subchannel to a different value to separate the various networks. The

For larger wireless networks, use the domain to establish roaming subnetworks
throughout your building. Only clients with the same domain will roam from
one Access Point to another.

0100 Access Point User’s Manual

Understanding the Spanning Tree Protocol Parameters

The 0100 Access Point meets the IEEE 802.1d Spanning Tree Protocol
specification. This protocol handles a complex bridged network (multiple
bridges) where loops are created either unintentionally or to provide
redundancy in the network. The bridges configure themselves into a spanning
tree topology, removing any loops within the network. If you administer a
network with more than one bridge, you will probably need to have some
understanding of this protocol so that you can configure your bridges for
optimum performance.

One of the bridges will become the root of the spanning tree. This root is
determined by the bridge with the lowest spanning tree priority on the
network. This bridge determines when all the bridges will broadcast their
priorities, physical addresses, activity states, and other parameters. This
communication is sent in “hello packets,” and the root bridge determines the
interval between these packets called the “hello time.”

Once a root to the tree is established, all other bridges on the network must
become branches. The order of the branches is determined by the spanning tree
priority, path cost (number of jumps away from the root), and port priority for
each bridge and each port on each bridge.

B-6

Where redundant bridges cause loops in the network, these loops are resolved
by one of the bridges becoming inactive. This means the bridge will no longer
forward packets of data that are sent to it. If the loops were not resolved, the
same packet of data could travel around the network forever.

The network’s bridges determine which bridge should become inactive based
on several parameters. You can configure these parameters on an Access Point
using the configuration program CFG.EXE, or on a network management
station that supports the IEEE 802.1d Bridge MIB (RFC 1493).

Spanning Tree Priority

This parameter sets the priority of an Access Point in the spanning tree created
on the network. Use it to determine the root node and the branches of the tree
and to resolve conflicts over which bridge on a network will become inactive
when there is a loop. In the event that two bridges have the same priority, the
unique physical address breaks the tie. The lower value has the higher priority.

For this parameter, you may choose a value of 0 to 65,535, with a default value
of 32,768.

Appendix B

B

Bridge Max Age

When the Access Point acts as the root, it uses this parameter to determine the
maximum amount of time before discarding hello packet data for all bridges on
the network.

This parameter is specified in seconds between 6 and 40, with a default value of

20.

Bridge Hello Timer

When the Access Point acts as the root, it uses this parameter to determine the
interval of time between hello packets. If this parameter is set too high, the
network will not quickly resolve contention problems. However, if the
parameter is set too low, the network will be crowded with hello packet traffic.

This parameter is specified in seconds between 1 and 10, with a default value of

2.

Bridge Forward Delay

This parameter specifies the amount of time it takes to transition between port
states after reset of the Access Point. The state transitions are as follows:

• disabled

• blocking incoming packets

• listening for other bridges

• learning the addresses of other bridges

• forwarding data
This parameter is specified in seconds between 4 and 30, with a default value of

15.

Aging Time

This parameter specifies the time after which the learned physical address of
the network node is discarded. This data is dynamically acquired by the Access
Point so that it can forward packets properly.

This parameter is specified in seconds between 10 and 1,000,000, with a default
value of 300.

B-7

0100 Access Point User’s Manual

RF Port Priority and Ethernet Port Priority

These parameters are used in the spanning tree algorithm to determine the
place of the port in the tree as well as to resolve loop contention problems. The
lower value has the higher priority. You can set this parameter for both the RF
port and the Ethernet port.

These parameters range from 0 to 255, with default values of 128.

RF Port Enabled and Ethernet Port Enabled

If either port is disabled, the Access Point will not forward data packets to the
network through this port. Since there are only two ports on the Access Point,
disabling either port would make the entire bridge inactive.

RF Port Path Cost and Ethernet Port Path Cost

These parameters specify the cost that is added to the spanning tree for this
port of the Access Point. This cost applies only when the Access Point is not the
root of the tree and when the port you are setting is the root port of the two
Access Point ports.

B-8

The parameter range is 1 to 65535, with a default value of 100 for the Ethernet
port and 625 for the RF port.
