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.

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-4/5/6 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-4/5/6 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-4/5/6 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-4/5/6 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/HTTPS Interface
• Command Line Interface
• SNMP Management
HTTP/HTTPS 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 Web or 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.
HTTPS provides an HTTP connection over a Secure Socket Layer.
HTTPS is one of two available secure management options on the AP;
the other secure management option is SNMPv3. Enabling HTTPS allows
you to access the AP in a secure fashion using Secure Socket Layer
(SSL) over port 443. The AP supports SSLv3 with a 128-bit encryption
certificate maintained by the AP for secure communications between the
AP and the HTTP client. All communications are encrypted using the
server and the client-side certificate.
1-8 Avaya Wireless AP-4/5/6 User’s Guide
Management and Monitoring Capabilities
The AP comes pre-installed with all required SSL files: default certificate,
private key and SSL Certificate Passphrase installed.
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.
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.
Avaya Wireless AP-4/5/6 User’s Guide 1-9
Management and Monitoring Capabilities
See The Command Line Interface for more information on the CLI and for
a list of CLI commands and parameters.
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.

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.
SNMPv3 Secure Management
SNMPv3 is one of two available secure management options on the AP;
the other secure management option is HTTPS (HTTP connection over
Secure Socket Layer). SNMPv3 is based on the existing SNMP
framework, but addresses security requirements for device and network
management.
The security threats addressed by Secure Management are:
• Modification of information: An entity could alter an in-transit
message generated by an authorized entity in such a way as to
effect unauthorized management operations, including the setting of
object values. The essence of this threat is that an unauthorized
entity could change any management parameter, including those
related to configuration, operations, and accounting
• Masquerade: Management operations that are not authorized for
some entity may be attempted by that entity by assuming the identity
of an authorized entity.

Management and Monitoring Capabilities
• Message stream modification: SNMP is designed to operate over a
connectionless transport protocol. There is a threat that SNMP
messages could be reordered, delayed, or replayed (duplicated) to
effect unauthorized management operations. For example, a
message to reboot a device could be copied and replayed later.
• Disclosure: An entity could observe exchanges between a manager
and an agent and thereby learns the values of managed objects and
learn of notifiable events. For example, the observation of a set
command that changes passwords would enable an attacker to
learn the new passwords.
To address the security threats listed above, SNMPv3 provides the
following when secure management is enabled:
• Authentication: Provides data integrity and data origin
authentication.
• Privacy (a.k.a Encryption): Protects against disclosure of message
payload.
• Access Control: Controls and authorizes access to managed objects
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.
