Introduction

In This Chapter

The following topics are covered in this section:

• Document Conventions

• Introduction to Wireless Networking

• IEEE 802.11 Specifications

• Management and Monitoring Capabilities

Document Conventions

• The term, AP, refers to an Access Point.

• The term, 802.11, is used to describe features that apply to the

802.11a, 802.11b, and 802.11g wireless standards.

• A Dual-radio AP is an Access Point that includes two radios; it can
support one or two IEEE radio standards (depending on the type of
radios installed). The AP-3 is a Dual-radio AP.

• An 802.11a AP is an Access Point that supports the IEEE 802.11a
standard.

• An 802.11b AP is an Access Point that supports the IEEE 802.11b
standard.

• An 802.11b/g AP is an Access Point that supports the IEEE 802.11g

NOTE:

A Note indicates important information that helps you make better
use of your computer.

CAUTION:

A Caution indicates either potential damage to hardware or loss of data
and tells you how to avoid the problem.

Introduction to Wireless Networking

An AP extends the capability of an existing Ethernet network to devices
on a wireless network. Wireless devices can

• connect to a single Access Point, or

• move between multiple Access Points located within the same

vicinity. As wireless clients move from one coverage cell to another,
the devices maintain network connectivity.

1-2 Avaya Wireless AP-3 User’s Guide

Introduction to Wireless Networking

Site Survey

To determine the best location for an Access Point, Avaya recommends
conducting a Site Survey before placing the device in its final location. For
information about how to conduct a Site Survey, contact your local
reseller.

Before an Access Point can be configured for your specific networking
requirements, it must first be initialized. See Getting Started for details.

Figure 1-1. Typical wireless network access infrastructure

Avaya Wireless AP-3 User’s Guide 1-3

Introduction to Wireless Networking

Once initialized, the network administrator can configure each unit
according to the network’s requirements. The AP functions as a wireless
network access point to data networks. An AP network provides:

• Seamless client roaming

• Easy installation and operation

• Over-the-air encryption of data

• High speed network links

To be fully operational, the AP-3 needs at least one wireless card
installed.

Guidelines for Roaming

Wireless Standard Support

An AP can only communicate with client devices that support its wireless
standard. For example, an 802.11a client cannot communicate with an

802.11b AP and an 802.11b client cannot communicate with an 802.11a
AP. However, both 802.11b and 802.11g clients can communicate with
an 802.11b/g AP.

1-4 Avaya Wireless AP-3 User’s Guide

Introduction to Wireless Networking

Network Names

• All Access Points must have the same Network Name to support
client roaming.

• All workstations with an 802.11 client adapter installed must use
either a Network Name of “any” or the same Network Name as the
Access Points that they will roam between. If an AP has Closed
System enabled, a client must have the same Network Name as the
Access Point to communicate (see Interfaces).

Security Settings

All Access Points and clients must have the same security settings to
communicate.

Cell Coverage

• The Access Points’ cells must overlap to ensure that there are no
gaps in coverage and to ensure that the roaming client will always
have a connection available.

• The coverage area of an 802.11b or 802.11b/g AP is larger than the
coverage area of an 802.11a AP. The 802.11b and 802.11b/g APs
operate in the 2.4 GHz frequency band; the 802.11a AP operates in
the 5 GHz band. Products that operate in the 2.4 GHz band offer
greater range than products that operate in the 5 GHz band.

Avaya Wireless AP-3 User’s Guide 1-5

IEEE 802.11 Specifications

Data Rates

An 802.11a or 802.11b/g AP operates at faster data rates than the

802.11b AP. 802.11a and 802.11g products operate at speeds of up to 54
Mbits/sec; 802.11b products operate at speeds of up to 11 Mbits/sec.

Channels

• All Access Points in the same vicinity should use a unique,
independent Channel. By default, the AP automatically scans for
available Channels during boot-up but you can also set the Channel
manually (see Interfaces for details).

• Access Points that use the same Channel should be installed as far
away from each other as possible to reduce potential interference.

IEEE 802.11 Specifications

In 1997, the Institute of Electrical and Electronics Engineers (IEEE)
adopted the 802.11 standard for wireless devices operating in the 2.4
GHz frequency band. This standard includes provisions for three radio
technologies: direct sequence spread spectrum, frequency hopping
spread spectrum, and infrared. Devices that comply with the 802.11
standard operate at a data rate of either 1 or 2 Megabits per second
(Mbits/sec).

1-6 Avaya Wireless AP-3 User’s Guide

IEEE 802.11 Specifications

802.11b

In 1999, the IEEE modified the 802.11 standard to support direct
sequence devices that can operate at speeds of up to 11 Mbits/sec. The
IEEE ratified this standard as 802.11b. 802.11b devices are backwards
compatible with 2.4 GHz 802.11 direct sequence devices (that operate at
1 or 2 Mbits/sec). Available Frequency Channels vary by regulatory
domain and/or country. See 802.11b Channel Frequencies for details.

802.11a

Also in 1999, the IEEE modified the 802.11 standard to support devices
operating in the 5 GHz frequency band. This standard is referred to as

802.11a. 802.11a devices are not compatible with 2.4 GHz 802.11 or

802.11b devices. 802.11a radios use a radio technology called
Orthogonal Frequency Division Multiplexing (OFDM) to achieve data
rates of up to 54 Mbits/sec. Available Frequency Channels vary by
regulatory domain and/or country. See 802.11a Channel Frequencies for
details.

802.11g

In 2003, the IEEE introduced the 802.11g standard. 802.11g devices
operate in the 2.4 GHz frequency band using OFDM to achieve data rates
of up to 54 Mbits/sec. In addition, 802.11g devices are backwards
compatible with 802.11b devices. Available Frequency Channels vary by
regulatory domain and/or country. See 802.11g Channel Frequencies for
details.

Management and Monitoring Capabilities

Management and Monitoring Capabilities

There are three management and monitoring interfaces available to the
network administrator to configure and manage an AP on the network:

• HTTP Interface

• Command Line Interface

• SNMP Management

HTTP Interface

The HTTP Interface (also known as the Web browser Interface) provides
easy access to configuration settings and network statistics from any
computer on the network. You can access the HTTP Interface:

• over your LAN (switch, hub, etc.),

• over the Internet, or

• with a “crossover” Ethernet cable connected directly to your

computer’s Ethernet Port.

Command Line Interface

The Command Line Interface (CLI) is a text-based configuration utility
that supports a set of keyboard commands and parameters to configure
and manage an AP.

1-8 Avaya Wireless AP-3 User’s Guide

Management and Monitoring Capabilities

Users enter Command Statements, composed of CLI Commands and
their associated parameters. Statements may be issued from the
keyboard for real time control, or from scripts that automate configuration.

For example, when downloading a file, administrators enter the
download CLI Command along with IP Address, file name, and file type
parameters.

How To Access the CLI

You access the CLI over a HyperTerminal serial connection or via Telnet.

During initial configuration, you can use the CLI over a serial port
connection to configure an Access Point’s IP address.

When accessing the CLI via Telnet, you can communicate with the
Access Point from over your LAN (switch, hub, etc.), from over the
Internet, or with a “crossover” Ethernet cable connected directly to your
computer’s Ethernet Port.

See Command Line Interface (CLI) for more information on the CLI and
for a list of CLI commands and parameters.

Avaya Wireless AP-3 User’s Guide 1-9

Management and Monitoring Capabilities

SNMP Management

You can also manage and configure an AP using the Simple Network
Management Protocol (SNMP).

NOTE:

This requires an SNMP manager program, like HP Openview or
Castlerock’s SNMPc.

The AP supports several Management Information Base (MIB) files that
describe the parameters that can be viewed and/or configured over
SNMP:

• MIB-II (RFC 1213)

• Bridge MIB (RFC 1493)

• Ethernet-like MIB (RFC 1643)

• 802.11 MIB

• Avaya Wireless Enterprise MIB

Avaya provides these MIB files on the CD included with each
Access Point. You need to compile one or more of the above MIBs into
your SNMP program’s database before you can manage an Access Point
using SNMP. Refer to the documentation that came with your SNMP
manager for instructions on how to compile MIBs.

1-10 Avaya Wireless AP-3 User’s Guide

Management and Monitoring Capabilities

The Enterprise MIB defines the read and read-write objects that can be
viewed or configured using SNMP. These objects correspond to most of
the settings and statistics that are available with the other management
interfaces. Refer to the Enterprise MIB for more information; the MIB can
be opened with any text editor, such as Microsoft Word, Notepad, or
WordPad.

NOTE:

The remainder of this guide describes how to configure an AP using
the HTTP Web interface or the CLI interface. For information on
how to manage devices using SNMP, refer to the documentation
that came with your SNMP program. Also, refer to the MIB files for
information on the parameters available via SNMP.

Initialization

Initialization

Avaya provides two tools to simplify the initialization and configuration of
an AP:

• ScanTool

• Setup Wizard

ScanTool is included on the Installation CD; the Setup Wizard launches
automatically the first time you access the HTTP interface.

NOTE:

These initialization instructions describe how to configure an AP
over an Ethernet connection using ScanTool and the HTTP
interface. If you want to configure the unit over the serial port, see

Setting IP Address using Serial Port for information on how to

access the CLI over a serial connection and Command Line

Interface (CLI) for a list of supported commands.

Avaya Wireless AP-3 User’s Guide 2-19

Initialization

ScanTool

ScanTool is a software utility that is included on the installation CD-ROM.
The tool automatically

• detects the Access Points installed on your network, regardless of
IP address,

• lets you configure each unit’s IP settings, and

• allows you to download new software to an AP that does not have a

valid software image installed (see Client Connection Problems).

To access the HTTP interface and configure the AP, the AP must be
assigned an IP address that is valid on its Ethernet network. By default,
the AP is configured to obtain an IP address automatically from a network
Dynamic Host Configuration Protocol (DHCP) server during boot-up. If
your network contains a DHCP server, you can run ScanTool to find out
what IP address the AP has been assigned.

Default IP Address

If your network does not contain a DHCP server, the Access Point’s IP
address defaults to 10.0.0.1. In this case, you can use ScanTool to assign
the AP a static IP address that is valid on your network.

ScanTool Instructions

Follow these steps to install ScanTool, initialize the Access Point, and
perform initial configuration:

2-20 Avaya Wireless AP-3 User’s Guide

Initialization

1. Locate the unit’s Ethernet MAC address and write it down for future
reference. The MAC address is printed on the product label. Each
unit has a unique MAC address, which is assigned at the factory.

2. Confirm that the AP is connected to the same LAN subnet as the
computer that you will use to configure the AP.

3. Power up, reboot, or reset the AP.

Download the Latest Software

Three types of files can be downloaded to the AP from a TFTP server:

• img (AP software image or kernel)

• config (configuration file)

• bspBl (BSP/Bootloader firmware file)

Setup your TFTP Server

A Trivial File Transfer Protocol (TFTP) server allows you to transfer files
across a network. You can

• upload files from the AP for backup or copying, and

• download the files for configuration and AP Image upgrades.

The Solarwinds TFTP server software is located on the Avaya Wireless
AP Installation CD-ROM. You can also download the latest TFTP
software from Solarwind’s Web site at http://www.solarwinds.net.

If a TFTP server is not configured and running, you will not be able to
download and upload images and configuration files to/from the AP.
Remember that the TFTP server does not have to be local as long as you
have a valid TFTP IP address. Also, a TFTP server does not have to be
running for the AP to perform tasks that do not involve file transfers.

Avaya Wireless AP-3 User’s Guide 2-45

Installing the AP in a Plenum

In an office building, plenum is the space between the structural ceiling
and the tile ceiling that is provided to help air circulate. Many companies
also use the plenum to house communication equipment and cables.
However, these products and cables must comply with certain safety
requirements, such as Underwriter Labs (UL) Standard 2043: “Standard
for Fire Test for Heat and Visible Smoke Release for Discrete Products
and Their Accessories Installed in Air-Handling Spaces”.

The AP has been certified under UL Standard 2043 and can be installed
in the plenum only when the following conditions apply:

• The unit's plastic cover has been removed.

• The power supply of the Access Point has been removed.

• There are two 802.11b cards in the cards slots.

OR

• There is one 802.11b card and the other card slot is protected with
the metal faceplate provided in your kit.

2-48 Avaya Wireless AP-3 User’s Guide

Additional Hardware Features

NOTE:

The 5GHz Antenna Adapter Kit or 11a Upgrade Kit is not approved
in accordance with UL-2043 for use in a plenum. The Access Point
using a power supply, should not be plenum mounted. Use Active
Ethernet to power the units mounted in a plenum environment.

Installing/Removing the Metal Faceplate

1. When using only one card in the Access Point mounted in a
plenum environment, remove the plastic cover.

2. Place the top edge of the faceplate under the front ridge of the
metal enclosure.

3. Snap the faceplate in the empty card slot in the Access Point.

!

CAUTION:

Do not drop the faceplate into the card slot in the AP.

4. To install a second radio card, the faceplate must be removed.
Gently pry the faceplate off using the tab on the faceplate.

Active Ethernet

An Active Ethernet-enabled AP is equipped with an 802.3af-compliant
Active Ethernet module. Active Ethernet (AE) delivers both data and
power to the access point over a single Ethernet cable. If you choose to
use Active Ethernet, there is no difference in operation; the only
difference is in the power source.

Avaya Wireless AP-3 User’s Guide 2-49

Additional Hardware Features

• The Active Ethernet (AE) integrated module receives ~48 VDC over
a standard Category 5 Ethernet cable.

• To use Active Ethernet, you must have an AE hub (also known as a
power injector) connected to the network.

• The cable length between the AE hub and the Access Point should
not exceed 100 meters (approximately 325 feet).

• The AE hub is not a repeater and does not amplify the Ethernet data
signal.

• If connected to an AE hub and an AC power simultaneously, the
Access Point draws power from Active Ethernet.

• Maximum power supplied to an Access Point is 11 Watts; the unit
typically draws approximately 10 Watts.

Also see Hardware Specifications.

NOTE:

The AP’s 802.3af-compliant Active Ethernet module is backwards
compatible with all Avaya Wireless Active Ethernet hubs that do not
support the IEEE 802.3af standard.

Default TTL (Time to Live): Time to Live (TTL) is a field in an IP packet
that specifies how long in seconds the packet can remain active on the
network. The Access Point uses the default TTL for packets it generates
for which the transport layer protocol does not specify a TTL value. This
parameter supports a range from 0 to 65535. By default, TTL is 64.

DHCP Server

If your network does not have a DHCP Server, you can configure the AP
as a DHCP server to assign dynamic IP addresses to Ethernet nodes and
wireless clients.

!

CAUTION:

Make sure there are no other DHCP servers on the network and do not
enable the DHCP server without checking with your network administrator
first, as it could bring down the whole network. Also, the AP must be con­figured with a static IP address before enabling this feature.

When the DHCP Server functionality is enabled, you can create one or
more IP address pools from which to assign addresses to network
devices.
