Introduction to Wireless Networking
! 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.

Avaya Wireless AP-8 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.

Avaya Wireless AP-8 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
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-8 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 for 802.11b or 802.11b/g radios is larger than the
coverage area of an 802.11a radio. The 802.11b and 802.11b/g
radios operate in the 2.4 GHz frequency band; the 802.11a radio
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-8 User’s Guide

IEEE 802.11 Specifications
Data Rates
An 802.11a or 802.11b/g radio operates at faster data rates than the
802.11b radio. 802.11a and 802.11g radios operate at speeds of up to 54
Mbits/sec; 802.11b radios 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-8 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-8 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-8 User’s Guide
1-9
Management and Monitoring Capabilities
See Command Line Interface (CLI) 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.
1-10
Avaya Wireless AP-8 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.
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.
Avaya Wireless AP-8 User’s Guide
1-11
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.

AP-8 Hardware Description
Dual Band Range Extender Antenna Description
The AP-8 can use internal or external antennas. The AP-8 has two
diversity antennas embedded for each radio system.
For each radio, the internal antennas are arranged to provide both spatial
and polarization diversity.
The AP-8 also has four external antenna connectors, two on each radio,
for use with the Dual Band Range Extender Antenna (Dual REA).
The Dual Band REA is a dual band indoor antenna that works with both
2.4 GHz (802.11b/g) and 5 GHz (802.11a) radios. The Dual Band REA
can be used with either radio on the AP-8, or with the AP-4, 5, or 6. The
Dual Band REA allows for better antenna placement for optimizing cell
size.
Antenna Diversity Options
With one Dual Band REA connected to one of the two antenna
connectors on a radio, the AP supports antenna diversity (one embedded
antenna and one external REA) and one of the two embedded antennas
is disabled.
With two Dual Band REAs connected to the two antenna connectors the
AP supports antenna diversity (two external REAs) and both embedded
antennas are disabled.
Refer to the Specifications chapter for more information on the REA.

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

ScanTool
ScanTool is a software utility that is included on the installation CD-ROM.
ScanTool allows you to find the IP address of an Access Point by
referencing the MAC address in a Scan List, or to assign an IP address if
one has not been assigned.
ScanTool 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.
Default IP Address
If your network does not contain a DHCP server, the Access Point’s IP
address defaults to 169.254.128.132. 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:
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.
— Result: The unit requests an IP Address from the network
DHCP server.
4. Insert the Installation CD into the CD-ROM drive of the computer
that you will use to configure the AP.
— Result: The installation program will launch automatically.
5. Follow the on-screen instructions to install the Access Point
software and documentation.

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.
Power over Ethernet
An Power over Ethernet-enabled AP is equipped with an
802.3af-compliant Power over Ethernet module. Power over Ethernet
(PoE) delivers both data and power to the access point over a single
Ethernet cable. If you choose to use Power over Ethernet, there is no
difference in operation; the only difference is in the power source.
2-44
Avaya Wireless AP-8 User’s Guide
Additional Hardware Features
• The Power over Ethernet (PoE) integrated module receives ~48
VDC over a standard Category 5 Ethernet cable.
• To use Power over Ethernet, you must have an PoE hub (also
known as a power injector) connected to the network.
• The cable length between the PoE hub and the Access Point should
not exceed 100 meters (approximately 325 feet).
• The PoE hub is not a repeater and does not amplify the Ethernet
data signal.
• If connected to an PoE hub and an AC power simultaneously, the
Access Point draws power from Power over Ethernet.
Also see Hardware Specifications.
NOTE:
The AP’s 802.3af-compliant Power over Ethernet module is
backwards compatible with all Avaya Wireless Power over Ethernet
hubs that do not support the IEEE 802.3af standard.

DNS is a distributed database mapping the user readable names and IP
addresses (and more) of every registered system on the Internet.
Dynamic DNS is a lightweight mechanism which allows for modification of
the DNS data of host systems whose IP addresses change dynamically.
Dynamic DNS is usually used in conjunction with DHCP for assigning
meaningful names to host systems whose IP addresses change
dynamically.
Access Points provide DDNS support by adding the host name (option
12) in DHCP Client messages, which is used by the DHCP server to
dynamically update the DNS server.
Access Point System Naming Convention
The Access Point's system name is used as its host name. In order to
prevent Access Points with default configurations from registering similar
host names in DNS, the default system name of the Access Point is
uniquely generated. Access Points generate unique system names by
appending the last 3 bytes of the Access Point's MAC address to the
default system name.
4-8
Avaya Wireless AP-8 User’s Guide
System
The system name must be compliant with the encoding rules for host
name as per DNS RFC 1123. The DNS host name encoding rules are:
• Characters have to alphanumeric or hyphen.
• The name cannot start or end with a hyphen.
• The name cannot start with a digit.
• The number of characters has to be 63 or less. (Currently the system
name length is limited to 32 bytes).
Image upgrades could cause the system to boot with an older system
name format that is not DNS compliant. To prevent problems with
dynamic DNS after an image upgrade, the system name will automatically
be converted to a DNS compliant system name.
The rules of conversion of older system names are:
• If the length is greater than 63 then the string is truncated. (This will
not happen since the system name is anyway limited to 32 bytes)
• All invalid characters at the beginning or end of the string are
replaced with the character 'X'.
• All other invalid characters are replaced with hyphens.

The gateway IP address will default to
169.254.128.133 if the unit cannot obtain an
address from a DHCP server.
DNS Client
If you prefer to use host names to identify network servers rather than IP
addresses, you can configure the AP to act as a Domain Name Service
(DNS) client. When this feature is enabled, the Access Point contacts the
network’s DNS server to translate a host name to the appropriate network
IP address. You can use this DNS Client functionality to identify RADIUS
servers by host name. See RADIUS for details.

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

listed within the table. If the AP loses network connectivity (that is, the
ping attempts fail), the AP disables its wireless interface until the
connection is restored. This forces the unit’s wireless clients to switch to
another Access Point that still has a network connection. Note that this
feature does not affect WDS links (if WDS links are configured and
enabled).

RTS/CTS Medium
Reservation
This parameter affects message flow control
and should not be changed under normal
circumstances. Range is 0 to 2347. When set
to a value between 0 and 2347, the
Access Point uses the RTS/CTS mechanism
for packets that are the specified size or
greater. When set to 2347 (the default
setting), RTS/CTS is disabled. See RTS/CTS
Medium Reservation for more information.

Dynamic Frequency Selection (DFS)
AP-8s sold in Europe use a technique called Dynamic Frequency
Selection (DFS) to automatically select an operating channel. During
boot-up, the AP scans the available frequency and selects a channel that
is free of interference. If the AP subsequently detects interference on its
channel, it automatically reboots and selects another channel that is free
of interference.
Avaya Wireless AP-8 User’s Guide
4-29
Interfaces
DFS only applies to 802.11a APs used in Europe (i.e., units whose
regulatory domain is set to ETSI). The European Telecommunications
Standard Institute (ETSI) requires that 802.11a devices use DFS to
prevent interference with radar systems and other devices that already
occupy the 5 GHz band.
If you are using the AP-8 in Europe, keep in mind the following:
• DFS is not a configurable parameter. It is always enabled and
cannot be disabled.
• You cannot manually select the device’s operating channel; you
must let DFS select the channel.
• You cannot configure the Auto Channel Select option. Within the
HTTP interface, this option always appears enabled.
RTS/CTS Medium Reservation
The 802.11 standard supports optional RTS/CTS communication based
on packet size. Without RTS/CTS, a sending radio listens to see if
another radio is already using the medium before transmitting a data
packet. If the medium is free, the sending radio transmits its packet.
However, there is no guarantee that another radio is not transmitting a
packet at the same time, causing a collision. This typically occurs when
there are hidden nodes (clients that can communicate with the
Access Point but are out of range of each other) in very large cells.
4-30
Avaya Wireless AP-8 User’s Guide
Interfaces
When RTS/CTS occurs, the following occurs.
1. The sending radio first transmits a Request to Send (RTS) packet
to confirm that the medium is clear.
2. When the receiving radio successfully receives the RTS packet, it
transmits back a Clear to Send (CTS) packet to the sending radio.
3. When the sending radio receives the CTS packet, it sends the data
packet to the receiving radio. The RTS and CTS packets contain a
reservation time to notify other radios (including hidden nodes) that
the medium is in use for a specified period. This helps to minimize
collisions.
While RTS/CTS adds overhead to the radio network, it is particularly
useful for large packets that take longer to resend after a collision occurs.
RTS/CTS Medium Reservation is an advanced parameter and supports a
range between 0 and 2347 bytes. When set to 2347 (the default setting),
the RTS/CTS mechanism is disabled. When set to 0, the RTS/CTS
mechanism is used for all packets. When set to a value between 0 and
2347, the Access Point uses the RTS/CTS mechanism for packets that
are the specified size or greater. You should not need to enable this
parameter for most networks unless you suspect that the wireless cell
contains hidden nodes.
Avaya Wireless AP-8 User’s Guide

Interfaces
Multicast Rate
The multicast rate determines the rate at which broadcast and multicast
packets are transmitted by the Access Point to the wireless network.
Stations that are closer to the Access Point can receive multicast packets
at a faster data rate than stations that are farther away from the AP.
Therefore, you should set the Multicast Rate based on the size of the
Access Point’s cell.
NOTE:
Multicast Rate cannot be set by the HTTP interface, but must be set
via CLI.
Cells of different sizes have different capacities and, therefore, suit
different applications. For instance, a typical office has many stations that
require high bandwidth for complex, high-speed data processing. In
contrast, a typical warehouse has a few forklifts requiring low bandwidth
for simple transactions.
Cell capacities are compared in the following table, which shows that
small cells suit most offices and large cells suit most warehouses:

Coverage
The number of Access Points in a set area determines the network
coverage for that area.
• A large number of Access Points covering a small area is a
high-density cell.
• A few Access Points, or even a single unit, covering the same small
area would result in a low-density cell.
In both cases the actual area did not change — only the number of
Access Points covering the area changed.
In a typical office, a high density area consists of a number of
Access Points installed every 20 feet and each Access Point generates a
small radio cell with a diameter of about 10 feet. In contrast, a typical
warehouse might have a low density area consisting of large cells (with a
diameter of about 90 feet) and Access Points installed every 200 feet.

Wireless Distribution System (WDS)
A Wireless Distribution System (WDS) creates a link between two
802.11a, 802.11b, or 802.11b/g APs over their radio interfaces. This link
relays traffic from one AP that does not have Ethernet connectivity to a
second AP that has Ethernet connectivity. WDS allows you to configure

In the WDS Example below, AP 1 and AP 2 communicate over a WDS
link (represented by the blue line). This link provides Client 1 with access

between the Access Points over the WDS link.

Avaya Wireless AP-8 User’s Guide
Interfaces
Bridging WDS
Each WDS link is mapped to a logical WDS port on the AP. WDS ports
behave like Ethernet ports rather than like standard wireless interfaces:
on a BSS port, an Access Point learns by association and from frames;
on a WDS or Ethernet port, an Access Point learns from frames only.
When setting up a WDS, keep in mind the following:
• There are separate security settings for clients and WDS links.
The same WDS link security mode must be configured (currently
only None or WEP are supported) on each Access Point in the WDS
and the same WEP key must be configured.
• The WDS link shares the communication bandwidth with the clients.
Therefore, while the maximum data rate for the Access Point's cell
is 54 Mbits/second (802.11a, 802.11g only, or 802.bg modes) or 11
Mbits/second (802.11b only mode), client throughput will decrease
when the WDS link is active.
• If there is no partner MAC address configured in the WDS table, the
WDS port remains disabled.
• Each WDS port on a single AP should have a unique partner MAC
address. Do not enter the same MAC address twice in an AP’s WDS
port list.
• Each Access Point that is a member of the WDS must have the
same Channel setting to communicate with each other.

creating network loops between APs. For example, creating a WDS
link between two Access Points connected to the same Ethernet
network will create a network loop (if spanning tree is disabled). For
more information, refer to the Spanning Tree section.
WDS Setup Procedure
NOTE:
You must disable Auto Channel Select to create a WDS. Each
Access Point that is a member of the WDS must have the same
Channel setting to communicate with each other.
To setup a wireless backbone follow the steps below for each AP that you
wish to include in the Wireless Distribution System.
1. Confirm that Auto Channel Select is disabled.

Static MAC
The Static MAC Address filter optimizes the performance of a wireless
(and wired) network. When this feature is properly configured, the AP can
block traffic between wired devices and wireless devices based on MAC
address.
Avaya Wireless AP-8 User’s Guide
4-65
Filtering
For example, you can set up a Static MAC filter to prevent wireless clients
from communicating with a specific server on the Ethernet network. You
can also use this filter to block unnecessary multicast packets from being
forwarded to the wireless network.
NOTE:
The Static MAC Filter is an advanced feature. You may find it easier
to control wireless traffic via other filtering options, such as Ethernet
Protocol Filtering.
Each static MAC entry contains the following fields:
• Wired MAC Address
• Wired Mask
• Wireless MAC Address
• Wireless Mask
• Comment: This field is optional.
Each MAC Address or Mask is comprised of 12 hexadecimal digits (0-9,
A-F) that correspond to a 48-bit identifier. (Each hexadecimal digit
represents 4 bits (0 or 1).)
4-66
Avaya Wireless AP-8 User’s Guide
Filtering
Taken together, a MAC Address/Mask pair specifies an address or a
range of MAC addresses that the AP will look for when examining
packets. The AP uses Boolean logic to perform an “AND” operation
between the MAC Address and the Mask at the bit level. However, for
most users, you do not need to think in terms of bits. It should be
sufficient to create a filter using only the hexadecimal digits 0 and F in the
Mask (where 0 is any value and F is the value specified in the MAC
address). A Mask of 00:00:00:00:00:00 corresponds to all MAC
addresses, and a Mask of FF:FF:FF:FF:FF:FF applies only to the
specified MAC Address.
Example
For example, if the MAC Address is 00:20:A6:12:54:C3 and the Mask is
FF:FF:FF:00:00:00, the AP will examine the source and destination
addresses of each packet looking for any MAC address starting with
00:20:A6. If the Mask is FF:FF:FF:FF:FF:FF, the AP will only look for the
specific MAC address (in this case, 00:20:A6:12:54:C3).

UDP, or TCP/UDP), and filtering interfaces (Wireless only, Ethernet only,
all interfaces, or no interfaces) in order to block access to services, such
as Telnet and FTP, and traffic, such as NETBIOS and HTTP.

Bridge
The AP is a bridge between your wired and wireless networking devices.
As a bridge, the functions performed by the AP include:
• MAC address learning
• Forward and filtering decision making
• Spanning Tree protocol used for loop avoidance
Once the AP is connected to your network, it learns which devices are
connected to it and records their MAC addresses in the Learn Table. The
table can hold up to 10,000 entries. To view the Learn Table, click on the
Monitor button in the web interface and select the Learn Table tab.
The Bridge tab has four sub-categories.
• Spanning Tree
• Storm Threshold
• Intra BSS
• Packet Forwarding
4-94
Avaya Wireless AP-8 User’s Guide
Bridge
Spanning Tree
A Spanning Tree is used to avoid redundant communication loops in
networks with multiple bridging devices. Bridges do not have any inherent
mechanism to avoid loops, because having redundant systems is a
necessity in certain networks. However, redundant systems can cause
Broadcast Storms, multiple frame copies, and MAC address table
instability problems.
Complex network structures can create multiple loops within a network.
The Spanning Tree configuration blocks certain ports on AP devices to
control the path of communication within the network, avoiding loops and
following a spanning tree structure.
For more information on Spanning Tree protocol, please see Section 8.0
of the IEEE 802.1d standard. The Spanning Tree configuration options
are advanced settings. Avaya recommends that you leave these
parameters at their default values unless you are familiar with the
Spanning Tree protocol.
Storm Threshold
Storm Threshold is an advanced Bridge setup option that you can use to
protect the network against data overload by:
• Specifying a maximum number of frames per second as received
from a single network device (identified by its MAC address).
• Specifying an absolute maximum number of messages per port.
Avaya Wireless AP-8 User’s Guide
4-95
Bridge
The Storm Threshold parameters allow you to specify a set of thresholds
for each port of the AP, identifying separate values for the number of
broadcast messages/second and Multicast messages/second.
When the number of frames for a port or identified station exceeds the
maximum value per second, the AP will ignore all subsequent messages
issued by the particular network device, or ignore all messages of that
type.
• Address Threshold: Enter the maximum allowed number of
packets per second.
• Ethernet Threshold: Enter the maximum allowed number of
packets per second.
• Wireless Threshold: Enter the maximum allowed number of
packets per second.
Intra BSS
The wireless clients (or subscribers) that associate with a certain AP form
the Basic Service Set (BSS) of a network infrastructure. By default,
wireless subscribers in the same BSS can communicate with each other.
However, some administrators (such as wireless public spaces) may wish
to block traffic between wireless subscribers that are associated with the
same AP to prevent unauthorized communication and to conserve
bandwidth. This feature enables you to prevent wireless subscribers
within a BSS from exchanging traffic.
4-96
Avaya Wireless AP-8 User’s Guide
Bridge
Although this feature is generally enabled in public access environments,
Enterprise LAN administrators use it to conserve wireless bandwidth by
limiting communication between wireless clients. For example, this
feature prevents peer-to-peer file sharing or gaming over the wireless
network.
• To block Intra BSS traffic, set Intra BSS Traffic Operation to Block.
• To allow Intra BSS traffic, set Intra BSS Traffic Operation to
Passthru.
Packet Forwarding
The Packet Forwarding feature enables you to redirect traffic generated
by wireless clients that are all associated to the same AP to a single MAC
address. This filters wireless traffic without burdening the AP and
provides additional security by limiting potential destinations or by routing
the traffic directly to a firewall. You can redirect to a specific port (Ethernet
or WDS) or allow the bridge’s learning process (and the forwarding table
entry for the selected MAC address) to determine the optimal port.
NOTE:
The gateway to which traffic will be redirected should be node on
the Ethernet network. It should not be a wireless client.

RADIUS
RADIUS
The AP communicates with a network’s RADIUS server to provide the
following features:
• MAC Access Control by Means of RADIUS Authentication
• RADIUS Authentication with 802.1x
• RADIUS Accounting
The network administrator can configure multiple RADIUS Authentication
Servers for different Authentication types. The current available
authentication types are EAP/802.1x authentication and MAC-based
authentication.You can configure two separate sets of Primary and
Secondary RADIUS Servers for each of the two supported Authentication
types, 802.1x EAP Based authentication and MAC based authentication.
You can configure the AP to communicate with up to six different RADIUS
servers:
• Primary Authentication Server (MAC-based authentication)
• Back-up Authentication Server (MAC-based authentication)
• Primary Authentication Server (EAP/802.1x authentication)
• Back-up Authentication Server (EAP/802.1x authentication)

NOTE:
You must have configured the settings for at least one
Authentication server before configuring the settings for an
Accounting server.
The back-up servers are optional, but when configured, the AP will
communicate with the back-up server if the primary server is off-line. After
the AP has switched to the backup server, it will periodically check the
status of the primary RADIUS server every five (5) minutes. Once the
primary RADIUS server is again online, the AP automatically reverts from
the backup RADIUS server back to the primary RADIUS server. All
subsequent requests are then sent to the primary RADIUS server.
You can view monitoring statistics for each of the configured RADIUS
servers.
MAC Access Control by Means of RADIUS Authentication
If you want to control wireless access to the network and if your network
includes a RADIUS Server, you can store the list of MAC addresses on
the RADIUS server rather than configure each AP individually. From the
RADIUS Authentication tab, you can define the IP Address of the server
that contains a central list of MAC Address values that identify the
authorized stations that may access the wireless network. You must
specify information for at least the primary RADIUS server. The back-up
RADIUS server is optional.

RADIUS Accounting
Using an external RADIUS server, the AP can track and record the length
of client sessions on the access point by sending RADIUS accounting
messages per RFC2866. When a wireless client is successfully
authenticated, RADIUS accounting is initiated by sending an “Accounting
Start” request to the RADIUS server. When the wireless client session
ends, an “Accounting Stop” request is sent to the RADIUS server.
Session Length
Accounting sessions continue when a client reauthenticates to the same
AP. Sessions are terminated when:
• A client disassociates.
• A client does not transmit any data to the AP for a fixed amount of
time.
• A client is detected on a different interface.
If the client roams from one AP to another, one session is terminated and
a new session is begun.

4-112
Avaya Wireless AP-8 User’s Guide
Security Overview
WEP Encryption
The IEEE 802.11 standards specify an optional encryption feature, known
as Wired Equivalent Privacy or WEP, that is designed to provide a
wireless LAN with a security level equal to what is found on a wired
Ethernet network. WEP encrypts the data portion of each packet
exchanged on an 802.11 network using an Encryption Key (also known
as a WEP Key).
When Encryption is enabled, two 802.11 devices must have the same
Encryption Keys and both devices must be configured to use Encryption
in order to communicate. If one device is configured to use Encryption but
a second device is not, then the two devices will not communicate, even if
both devices have the same Encryption Keys.
• An 802.11b only radio supports 64-bit and 128-bit encryption:
— For 64-bit encryption, an encryption key is 10 hexadecimal
characters (0-9 and A-F) or 5 ASCII characters (see ASCII
Character Chart).
— For 128-bit encryption, an encryption key is 26 hexadecimal
characters or 13 ASCII characters.
Avaya Wireless AP-8 User’s Guide
4-113
Security Overview
• An 802.11a or 802.11b/g AP supports 64-bit, 128-bit, and 152-bit
encryption:
— For 64-bit encryption, an encryption key is 10 hexadecimal
characters (0-9 and A-F) or 5 ASCII characters (see ASCII
Character Chart).
— For 128-bit encryption, an encryption key is 26 hexadecimal
characters or 13 ASCII characters.
— For 152-bit encryption, an encryption key is 32 hexadecimal
characters or 16 ASCII characters.
NOTE:
64-bit encryption is sometimes referred to as 40-bit encryption;
128-bit encryption is sometimes referred to as 104-bit encryption.
802.1x Authentication
IEEE 802.1x is a standard that provides a means to authenticate and
authorize network devices attached to a LAN port. A port in the context of
IEEE 802.1x is a point of attachment to the LAN, either a physical
Ethernet connection or a wireless link to an Access Point. 802.1x requires
a RADIUS server and uses the Extensible Authentication Protocol (EAP)
as a standards-based authentication framework, and supports automatic
key distribution for enhanced security. The EAP-based authentication
framework can easily be upgraded to keep pace with future EAP types.

Avaya Wireless AP-8 User’s Guide
4-115
Security Overview
Different servers support different EAP types and each EAP type provides
different features. Refer to the documentation that came with your
RADIUS server to determine which EAP types it supports.
NOTE:
The AP supports the following EAP types when Authentication
Mode is set to 802.1x or WPA: EAP-TLS, PEAP, and EAP-TTLS.
When Authentication Mode is set to Mixed, the AP supports the
following EAP types: EAP-TLS, PEAP, EAP-TLLS, and EAP-MD5
(MD5 does not support automatic key distribution; therefore, if you
choose this method you need to manually configure each client with
the network's encryption key).
Authentication Process
There are three main components in the authentication process. The
standard refers to them as:
1. supplicant (client PC)
2. authenticator (Access Point)
3. authentication server (RADIUS server)
When using Authentication Mode is set to 802.1x, WPA, or Mixed mode
(802.1x and WEP), you need to configure your RADIUS server for
authentication purposes.
4-116
Avaya Wireless AP-8 User’s Guide
Security Overview
Prior to successful authentication, an unauthenticated client PC cannot
send any data traffic through the AP device to other systems on the LAN.
The AP inhibits all data traffic from a particular client PC until the client PC
is authenticated. Regardless of its authentication status, a client PC can
always exchange 802.1x messages in the clear with the AP (the client
begins encrypting data after it has been authenticated).
Figure 4-18.
RADIUS Authentication Illustrated
The AP acts as a pass-through device to facilitate communications
between the client PC and the RADIUS server. The AP (2) and the client
(1) exchange 802.1x messages using an EAPOL (EAP Over LAN)
protocol (A). Messages sent from the client station are encapsulated by
the AP and transmitted to the RADIUS (3) server using EAP extensions
(B).
Avaya Wireless AP-8 User’s Guide
4-117
Security Overview
Upon receiving a reply EAP packet from the RADIUS, the message is
typically forwarded to the client, after translating it back to the EAPOL
format. Negotiations take place between the client and the RADIUS
server. After the client has been successfully authenticated, the client
receives an Encryption Key from the AP (if the EAP type supports
automatic key distribution). The client uses this key to encrypt data after it
has been authenticated.
For 802.11a and 802.11b/g clients that communicate with an AP, each
client receives its own unique encryption key; this is known as Per User
Per Session Encryption Keys.
Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access (WPA) is a security standard designed by the
Wi-Fi Alliance in conjunction with the Institute of Electrical and Electronics
Engineers (IEEE). WPA is a sub-set of the forthcoming IEEE 802.11i
security standard, currently in draft form. (IEEE 802.11i is also referred to
as “WPA2” and will be available in 2004.)
4-118
Avaya Wireless AP-8 User’s Guide
Security Overview
WPA is a replacement for Wired Equivalent Privacy (WEP), the
encryption technique specified by the original 802.11 standard. WEP has
several vulnerabilities that have been widely publicized. WPA addresses
these weaknesses and provides a stronger security system to protect
wireless networks.
WPA provides the following new security measures not available with
WEP:
• Improved packet encryption using the Temporal Key Integrity
Protocol (TKIP) and the Michael Message Integrity Check (MIC).
• Per-user, per-session dynamic encryption keys:
— Each client uses a different key to encrypt and decrypt unicast
packets exchanged with the AP
— A client's key is different for every session; it changes each
time the client associates with an AP
— The AP uses a single global key to encrypt broadcast packets
that are sent to all clients simultaneously
— Encryption keys change periodically based on the Re-keying
Interval parameter
— WPA uses 128-bit encryption keys
• Dynamic Key distribution
— The AP generates and maintains the keys for its clients
— The AP securely delivers the appropriate keys to its clients
Avaya Wireless AP-8 User’s Guide

Security Overview
• Client/server mutual authentication
— 802.1x
— Pre-shared key (for networks that do not have an 802.1x
solution implemented)
NOTE:
For more information on WPA, see the Wi-Fi Alliance Web site at
http://www.wi-fi.org.
The AP supports two WPA authentication modes:
• WPA: The AP uses 802.1x to authenticate clients. You should only
use an EAP that supports mutual authentication and session key
generation, such as EAP-TLS, EAP-TTLS, and PEAP. See 802.1x
Authentication for details.
• WPA-PSK (Pre-Shared Key): For networks that do not have 802.1x
implemented, you can configure the AP to authenticate clients
based on a Pre-Shared Key. This is a shared secret that is manually
configured on the AP and each of its clients. The Pre-Shared Key
must be 256 bits long, which is either 64 hexadecimal digits. The AP
also supports a PSK Pass Phrase option to facilitate the creation of
the Pre-Shared Key (so a user can enter an easy-to-remember
phrase rather than a string of characters).

SSID, VLAN, and Security Modes
NOTE:
Before enabling the 802.1x, Mixed, or WPA mode, the 802.1x server
should be configured.
SSID, VLAN, and Security Modes
The AP-8 allows you to:
• segment wireless networks into multiple sub-networks based on
Network Name (SSID) and VLAN membership, and
• apply security modes per SSID.
A Network Name (SSID) identifies a wireless network. Clients associate
with Access Points that share an SSID. During installation, the Setup
Wizard prompts you to configure a Primary Network Name for each
wireless interface.
After initial setup and once VLAN is enabled, the AP can be configured to
support up to 16 SSIDs per wireless interface to segment wireless
networks based on VLAN membership.
Refer to Configure Multiple SSID/VLAN/Security Mode Entries for
configuration details.
4-124
Avaya Wireless AP-8 User’s Guide
SSID, VLAN, and Security Modes
VLAN Overview
Virtual Local Area Networks (VLANs) are logical groupings of network
hosts. Defined by software settings, other VLAN members or resources
appear (to clients) to be on the same physical segment, no matter where
they are attached on the logical LAN or WAN segment. They simplify
traffic flow between clients and their frequently-used or restricted
resources.
VLANs now extend as far as the reach of the access point signal. Clients
can be segmented into wireless sub-networks via SSID and VLAN
assignment. A Client can access the network by connecting to an AP
configured to support its assigned SSID/VLAN.
AP devices are fully VLAN-ready; however, by default VLAN support is
disabled. Before enabling VLAN support, certain network settings should
be configured, and network resources such as a VLAN-aware switch, a
RADIUS server, and possibly a DHCP server should be available.
Once enabled, VLANs are used to conveniently, efficiently, and easily
manage your network in the following ways:
• Manage adds, moves, and changes from a single point of contact
• Define and monitor groups
• Reduce broadcast and multicast traffic to unnecessary destinations
— Improve network performance and reduce latency
• Increase security
Avaya Wireless AP-8 User’s Guide
4-125
SSID, VLAN, and Security Modes
— Secure network restricts members to resources on their own
VLAN
— Clients roam without compromising security
VLAN tagged data is collected and distributed through an AP's wireless
interface(s) based on Network Name (SSID). An Ethernet port on the
access point connects a wireless cell or network to a wired backbone.
The access points communicate across a VLAN-capable switch that
analyzes VLAN-tagged packet headers and directs traffic to the
appropriate ports. On the wired network, a RADIUS server authenticates
traffic and a DHCP server manages IP addresses for the VLAN(s).
Resources like servers and printers may be present, and a hub may
include multiple APs, extending the network over a larger area.
In this figure, the numbered items correspond to the following
components:
1. VLAN-enabled access point
2. VLAN-aware switch (IEEE 802.1Q uplink)
3. AP management via wired host (SNMP, Web interface or CLI)

Components of a Typical VLAN
Avaya Wireless AP-8 User’s Guide
4-127
SSID, VLAN, and Security Modes
VLAN Workgroups and Traffic Management
Access Points that are not VLAN-capable typically transmit broadcast and
multicast traffic to all wireless Network Interface Cards (NICs). This
process wastes wireless bandwidth and degrades throughput
performance. In comparison, VLAN-capable AP is designed to efficiently
manage delivery of broadcast, multicast, and unicast traffic to wireless
clients.
The AP assigns clients to a VLAN based on a Network Name (SSID). The
AP can support up to 16 SSID/VLAN pairs per radio.
The AP matches packets transmitted or received to a network name with
the associated VLAN. Traffic received by a VLAN is only sent on the
wireless interface associated with that same VLAN. This eliminates
unnecessary traffic on the wireless LAN, conserving bandwidth and
maximizing throughput.
Traffic Management
In addition to enhancing wireless traffic management, the VLAN-capable
AP supports easy assignment of wireless users to workgroups. In a
typical scenario, each user VLAN represents a workgroup; for example,
one VLAN could be used for an EMPLOYEE workgroup and the other, for
a GUEST workgroup.
4-128
Avaya Wireless AP-8 User’s Guide
SSID, VLAN, and Security Modes
In this scenario, the AP would assign every packet it accepted to a VLAN.
Each packet would then be identified as EMPLOYEE or GUEST,
depending on which wireless NIC received it. The AP would insert VLAN
headers or “tags” with identifiers into the packets transmitted on the wired
backbone to a network switch.
Finally, the switch would be configured to route packets from the
EMPLOYEE workgroup to the appropriate corporate resources such as
printers and servers. Packets from the GUEST workgroup could be
restricted to a gateway that allowed access to only the Internet. A
member of the GUEST workgroup could send and receive e-mail and
access the Internet, but would be prevented from accessing servers or
hosts on the local corporate network.
Typical User VLAN Configurations
VLANs segment network traffic into workgroups, which enable you to limit
broadcast and multicast traffic. Workgroups enable clients from different
VLANs to access different resources using the same network
infrastructure. Clients using the same physical network are limited to
those resources available to their workgroup.
The AP can segment users into a maximum of 16 different workgroups
(32 for the AP-8 which has two radios) based on an SSID/VLAN pair (also
referred as a VLAN Workgroup or a Sub-network).
The four primary scenarios for using VLAN workgroups are as follows:
Avaya Wireless AP-8 User’s Guide
4-129
SSID, VLAN, and Security Modes
1. VLAN disabled: Your network does not use VLANs, but you can
configure the AP to use multiple SSIDs.
2. VLAN enabled, all VLAN Workgroups use the same VLAN ID Tag
3. VLAN enabled, each VLAN workgroup uses a different VLAN ID
Tag
4. VLAN enabled, a mixture of Tagged and Untagged workgroups
Configure Multiple SSID/VLAN/Security Mode Entries
Each SSID/VLAN can have its own security mode, so that customers can
have multiple types of clients (non-WEP, WEP, 802.1x, WPA) on the
same system, but separated per VLAN.
NOTE:
You must reboot the AP before any changes to these parameters
take effect.
1. Click Configure > SSID/VLAN/Security > Mgmt VLAN.
2. Place a check mark in the Enable VLAN Protocol box to enable

SSID, VLAN, and Security Modes
— You must specify a unique VLAN ID for each SSID on the
interface. As defined by the 802.1Q standard, a VLAN ID is
a number between 1 and 4094. A value of -1 means that an
entry is "untagged".
— You can set the VLAN ID to "-1" or "untagged" if you do not
want clients that are using a specific SSID to be members of
a VLAN workgroup. Only one “untagged” VLAN ID is
allowed per interface.
— The VLAN ID must match an ID used by your network;
contact your network administrator if you need assistance
defining the VLAN IDs.
d. Select the security mode for the SSID/VLAN entry and
configure the security mode parameters according to one of
the following procedures:
NOTE:
If you have two or more SSIDs per interface with a security mode of
None, be aware that security being applied in the VLAN is not being

management stations or hosts and the AP itself members of a common
VLAN. Simply configure a non-zero management VLAN ID and enable
VLAN to restrict management of the AP to members of the same VLAN.
! CAUTION:
If a non-zero management VLAN ID is configured then management
access to the AP is restricted to wired or wireless hosts that are members
of the same VLAN. Ensure your management platform or host is a member of the same VLAN before attempting to manage the AP.
1. Click Configure > VLAN.
2. Set the VLAN Management ID to a value between 0 and 4094 (a

Rogue Access Point Detection (RAD)
Rogue Access Point Detection (RAD)
The Rogue AP Detection (RAD) feature provides an additional security
level for wireless LAN deployments. Rogue AP detection provides a
mechanism for detecting Rogue Access Points by utilizing the coverage
of the trusted Access Point deployment.
The Rogue AP Scan employs background scanning using low-level
802.11 scanning functions for effective wireless detection of Access
Points in its coverage area with minimal impact on the normal operation of
the Access Point.
This RAD feature can be enabled on an Access Point via its HTTP, CLI,
or SNMP Interfaces. The scan repetition duration is configurable. The
Access Point will periodically scan the wireless network and report all the
available Access Points within its coverage area using SNMP traps. For
additional reliability the results are stored in the Access Point in a table,
which can be queried via SNMP. The BSSID and Channel number of the
detected Access Points are provided in the scan results.
The RAD scan is done on a channel list initialized based on the regulatory
domain of the device. The RAD Scan then performs background scanning
on all the channels in this channel list using 802.11 MAC scanning
functions. It will either actively scan the network by sending probe
requests or passively scan by only listening for beacons. The access
point information is then gathered from the probe responses and
beacons.
4-142
Avaya Wireless AP-8 User’s Guide
Rogue Access Point Detection (RAD)
To minimize traffic disruption and maximize the scanning efficiency, the
RAD feature employs an enhanced background-scanning algorithm and
uses the CTS to Self mechanism to keep the clients silent. The scanning
algorithm allows traffic to be serviced between each channel scan. Before
start of every scan (except scan on the working channel) the CTS to
self-mechanism is used to set the NAV values of clients to keep them
silent during the scanning period. In addition, the scan repetition duration
can also be configured to reduce the frequency of RAD scan cycles to
maximize Access Point performance.
RAD Configuration Requirements
The RAD feature can be configured/monitored via the HTTP, CLI, or
SNMP management interfaces.
The following management options are provided:
• The RAD feature can be enabled or disabled.
• The repetition interval of RAD can be configured.
• The interface on which RAD can operate can be configured.
• SNMP Traps are sent after completion of a RAD scan cycle and also
whenever a new Access Point is detected.
• Additionally, the RAD scan results are maintained in a table that can
be queried via SNMP.

through HTTP or TFTP is valid. The following checks are performed on
the downloaded image:
• Zero Image size
• Large image size
• Non VxWorks image
• AP image
• Digital signature verification
If any of the above checks fail on the downloaded image, the Access
Point deletes the downloaded image and retains the old image.
Avaya Wireless AP-8 User’s Guide

Troubleshooting Concepts
Troubleshooting Concepts
The following list identifies important troubleshooting concepts and topics.
The most common initialization and installation problems relate to IP
addressing. For example, you must have valid IP addresses for both the
AP and the management computer to access the unit’s HTTP interface.
• IP Address management is fundamental.
• Factory default units are set for “Dynamic” (DHCP) IP Address
assignment. The default IP address for the AP is 169.254.128.132
if your network does not have a DHCP server. If you connect the AP
to a network with an active DHCP server, then use ScanTool to
locate the IP address of your unit. If a DHCP server is not active on
your subnet, then use ScanTool to assign a static IP address to the
unit.
• The Trivial File Transfer Protocol (TFTP) provides a means to
download and upload files. These files include the AP Image
(executable program) and configuration files.
• If the AP password is lost or forgotten, you will need to reset to
default values. The Reset to Factory Default Procedure resets
configuration, but does not change the current AP Image.
• If all else fails… Use the Forced Reload Procedure to erase the
current AP Image and then download a new image. Once the new
image is loaded, use the Reset to Factory Default Procedure to set
the unit to factory default values and reconfigure the unit.
7-2
Avaya Wireless AP-8 User’s Guide
Symptoms and Solutions
• The AP Supports a Command Line Interface (CLI). If you are
having trouble locating your AP on the network, connect to the unit
directly using the serial interface and refer to Command Line
Interface (CLI) for CLI command syntax and parameter names.
Symptoms and Solutions
Connectivity Issues
Connectivity issues include any problem that prevents you from powering
up or connecting to the AP.
AP Unit Will Not Boot - No LED Activity
1. Make sure your power source is operating.
2. Make sure all cables are connected to the AP correctly.
3. If you are using Power over Ethernet, make sure you are using a
Category 5, foiled, twisted pair cable to power the AP.

2. Double-check the physical network connections.
3. Make sure your PC terminal program (such as HyperTerminal) is
active and configured to the following values:
— Com Port: (COM1, COM2, etc. depending on your computer);
— Baud rate: 9600; Data bits: 8; Stop bits: 1; Flow Control: None;
Parity: None;
— Line Feeds with Carriage Returns
(In HyperTerminal select:

Avaya Wireless AP-8 User’s Guide
Symptoms and Solutions
Ethernet Link Does Not Work
1. Double-check the physical network connections. Use a
known-good unit to make sure the network connection is present.
Once you have the AP IP address, you can use the “Ping”
command over Ethernet to test the IP Address. If the AP responds
to the Ping, then the Ethernet Interface is working properly.
2. By default, the Access Point will attempt to automatically detect the
Ethernet settings. However, if you are having problems with the
Ethernet link, manually configure the Access Point’s Ethernet
settings. For example, if your switch operates at 100 Mbits/sec/Full
Duplex, manually configure the Access Point to use these settings
(see Ethernet). If you cannot access the unit over Ethernet, then
use the CLI interface over the serial port to configure the Ethernet
port (see Command Line Interface (CLI) and Set Ethernet Speed
and Transmission Mode).
3. Perform network infrastructure troubleshooting (check switches,
routers, etc.).

Avaya Wireless AP-8 User’s Guide
Symptoms and Solutions
AP Has Incorrect IP Address
1. Default IP Address Assignment mode is dynamic (DHCP). If you
do not have a DHCP server on your network, the default IP
Address is 169.254.128.132. If you have more than one
unintialized AP connected to the network, they will all have the
same default IP address and you will not be able to communicate
with them (due to an IP address conflict). In this case, assign each
AP a static IP address via the serial cable or turn off all units but
one and change the IP address using ScanTool one at a time.
2. The AP only contacts a DHCP server during boot-up. If your
network’s DHCP server is not available while the AP is booting, the
device will retain the last IP Address it had. Reboot the AP once
your DHCP server is on-line again or use the ScanTool to find the
Access Point’s current IP address.
3. To find the unit’s current IP address if using DHCP, open the IP
Client Table in the DHCP Server and match the Access Point’s IP
address to its MAC address (found on the product label).
Alternatively, use ScanTool to identify an Access Point’s current IP
address.
4. Once you have the current IP address, use the HTTP or CLI
Interface to change the unit’s IP settings, if necessary.
5. If you use static IP Address assignments, and cannot access the
unit over Ethernet, use the Initializing the IP Address using CLI
procedure. Once the IP Address is set, you can use the Ethernet
Interface to complete configuration.

6. Perform the Reset to Factory Default Procedure in this guide. This
will reset the unit to “DHCP” mode. If there is a DHCP Server on
the network, the DHCP Server will assign an IP Address to the AP.
HTTP (browser) or Telnet Interface Does Not Work
1. Make sure you are using a compatible browser:
— Microsoft Internet Explorer 6 with Service Pack 1 or later
— Netscape 6.1 or later
2. Make sure you have the proper IP address. Enter your
Access Point’s IP Address in the browser address bar, similar to
this example:
http://192.168.1.100
When the Enter Network Password window appears, leave the
User Name field empty and enter the HTTP password in the
Password field. The default HTTP password is “public”.
3. Use the CLI over the serial port to check the IP Access Table,
which can be restricting access to Telnet and HTTP.

Client Does Not Receive an IP Address - Cannot Connect to Internet
1. If the AP is configured as a DHCP server, open the Web-browser
Interface and select the Configure button and then the Network
tab to make sure the proper DHCP settings are being used.
2. If you are not using the DHCP server feature on the AP, then make
sure that your local DHCP server is accessible from the
Access Point’s subnet.
3. From the client computer, use the “ping” network command to test
the connection with the AP. If the AP responds, but you still cannot
connect to the Internet, there may be a physical network
configuration problem (contact your network support staff).
4. If using Power over Ethernet, make sure you are not using a
crossover Ethernet cable between the AP and the hub.

VLAN Operation Issues
Verifying Proper Operation of the VLAN Feature
The correct VLAN configuration can be verified by “pinging” both wired
and wireless hosts from both sides of the AP device and the network
switch. Traffic can be “sniffed” on both the wired (Ethernet) and wireless
(WDS) backbones (if configured). Bridge frames generated by wireless
clients and viewed on one of the backbones should contain IEEE 802.1Q
compliant VLAN headers or tags. The VLAN ID in the headers should
correspond to one of the VLAN User IDs configured for the AP.
NOTE:
The AP-8 supports 16 VLAN/SSID pairs, each with a configured
security mode.
VLAN Workgroups
The correct VLAN assignment can be verified by pinging the AP to ensure
connectivity, by pinging the switch to ensure VLAN properties, and by
pinging hosts past the switch to confirm the switch is functional.
Ultimately, traffic can be “sniffed” on the Ethernet or WDS interfaces (if
configured) using third-party packages. Most problems can be avoided by
ensuring that 802.1Q compliant VLAN tags containing the proper VLAN
ID have been inserted in the bridged frames. The VLAN ID in the header
should correspond to the user’s assigned network name.
7-12
Avaya Wireless AP-8 User’s Guide
Symptoms and Solutions
What if network traffic is being directed to a nonexistent host?
• All sessions are disconnected, traffic is lost, and a manual override
is necessary
• Workaround: you can configure the switch to mimic the nonexistent
host
I have just configured the Management ID and now I can't manage
the AP?
• Check to ensure your password is correct. If your password is
incorrect or all inbound packets do NOT have the correct tag, then
a manual override is necessary.
! CAUTION:
The manual override process disconnects all users and resets all values
to factory defaults.
Power over Ethernet (PoE)
Avaya Wireless AP-8 User’s Guide
7-13
Symptoms and Solutions
The AP Does Not Work
1. Verify that you are using a standard UTP Category 5 cable.
2. Try a different port on the same PoE hub (remember to move the
input port accordingly) – if it works, there is probably a faulty port or
bad RJ-45 port connection.
3. If possible, try to connect the AP to a different PoE hub.
4. Try using a different Ethernet cable – if it works, there is probably a
faulty connection over the long cable, or a bad RJ-45 connection.
5. Check power plug and hub.
6. If the Ethernet link goes down, check the cable, cable type, switch,
and hub.
There Is No Data Link
1. Verify that the indicator for the port is “on.”
2. Verify that the PoE hub is connected to the Ethernet network with a
good connection.
3. Verify that the Ethernet cable is Category 5 or better and is less
than 100 meters (approximately 325 feet) in length from the
Ethernet source to the AP.
4. Try to connect a different device to the same port on the PoE hub –
if it works and a link is established, there is probably a faulty data
link in the AP.

5. Try to re-connect the AP to a different output port (remember to
move the input port accordingly) – if it works, there is probably a
faulty output or input port in the PoE hub or a bad RJ-45
connection.
“Overload” Indications
1. Verify that you are not using a cross-over cable between the PoE
output port and the AP.
2. Verify that there is no short over any of the twisted pair cables.
3. Move the device into a different output port – if it works, there is
probably a faulty port or bad RJ-45 connection.
Recovery Procedures
The most common installation problems relate to IP addressing. For
example, without the TFTP server IP Address, you will not be able to
download a new AP Image to the AP. IP Address management is
fundamental. We suggest you create a chart to document and validate
the IP addresses for your system.
If the password is lost or forgotten, you will need to reset the AP to default
values. The Reset to Factory Default Procedure resets configuration
settings, but does not change the current AP Image.
If the AP has a corrupted software image, follow the Forced Reload
Procedure to erase the current AP Image and download a new image.

Recovery Procedures
Reset to Factory Default Procedure
Use this procedure to reset the network configuration values, including
the Access Point’s IP address and subnet mask. The current AP Image is
not deleted. Follow this procedure if you forget the Access Point’s
password:
1. Press and hold the RELOAD button for 10 seconds.
NOTE:
You need to use a pin or the end of a paperclip to press a button.
Result: The AP reboots, and the factory default network values
are restored.
2. If not using DHCP, use the ScanTool or CLI over a serial
connection to set the IP address, subnet mask, and other IP
parameters. See Command Line Interface (CLI) for CLI
information.

Recovery Procedures
Forced Reload Procedure
Use this procedure to erase the current AP Image and download a new
AP Image. In some cases, specifically when a missing or corrupted AP
Image prevents successful booting, you may need to use ScanTool or the
Bootloader CLI to download a new executable AP Image.
NOTE:
This does not delete the AP’s configuration (in other words, the
Forced Reload Procedure does not reset to device to factory
defaults). If you need to force the AP to the factory default state after
loading a new AP image, use the Reset to Factory Default
Procedure above.
For this procedure, you will first erase the AP Image currently installed on
the unit and then use either ScanTool or the Bootloader CLI (over the
serial port) to set the IP address and download a new AP Image. Follow
these steps:
1. While the unit is running, press the RESET button.
NOTE:
You need to use a pin or the end of a paperclip to press a button.
Result: The AP reboots and the indicators begin to flash.

! CAUTION:
By completing Step 2, the firmware in the AP will be erased. You will need
an Ethernet connection, a TFTP server, and a serial cable (if using the
Bootloader CLI) to reload firmware.
2. Press and hold the RELOAD button for about 20 seconds until the
POWER LED turns amber.
Result: The AP deletes the current AP Image.
3. Follow one of the procedures below to load a new AP Image to the
Access Point:
— Download a New Image Using ScanTool
— Download a New Image Using the Bootloader CLI
Download a New Image Using ScanTool
To download the AP Image, you will need an Ethernet connection to the
computer on which the TFTP server resides and to a computer that is
running ScanTool (this is either two separate computers connected to the
same network or a single computer running both programs).
ScanTool detects if an Access Point does not have a valid software
image installed. In this case, the TFTP Server and Image File Name
parameters are enabled in the ScanTool’s Change screen so you can
download a new image to the unit. (These fields are grayed out if
ScanTool does not detect a software image problem.)

Setting IP Address using Serial Port
Use the following procedure to set an IP address over the serial port
using the CLI. The network administrator typically provides the AP IP
address.
Hardware and Software Requirements
• Standard straight-through serial data (RS-232) cable with a one
male DB-9 connector and one female DB-9 connector. The AP
comes with a female 9-pin serial port.
• ASCII Terminal software, such as HyperTerminal.
Attaching the Serial Port Cable
1. Connect one end of the serial cable to the AP and the other end to
a serial port on your computer.
2. Power on the computer and AP, if necessary.
7-24
Avaya Wireless AP-8 User’s Guide
Recovery Procedures
Initializing the IP Address using CLI
After installing the serial port cable, you may use the CLI to communicate
with the AP. CLI supports most generic terminal emulation programs,
such as HyperTerminal (which is included with the Windows operating
systems). In addition, many web sites offer shareware or commercial
terminal programs you can download. Once the IP address has been
assigned, you can use the HTTP interface or the CLI over Telnet to
complete configuration.
Follow these steps to assign the AP an IP address:
1. Open your terminal emulation program (like HyperTerminal) and
set the following connection properties:
— Com Port: <COM1, COM2, etc., depending on your computer>
— Baud rate: 9600
— Data Bits: 8
— Stop bits: 1
— Flow Control: None
— Parity: None
2. Under File -> Properties -> Settings -> ASCII Setup, enable the
Send line ends with line feeds option.
Result: HyperTerminal sends a line return at the end of each line
of code.

6. Change the IP address and other network values using set and
reboot CLI commands, similar to the example below (use your
own IP address and subnet mask). Note that IP Address Type is
set to Dynamic by default. If you have a DHCP server on your
network, you should not need to manually configure the
Access Point’s IP address; the Access Point will obtain an IP
address from the network’s DHCP server during boot-up.
Result: After each entry the CLI reminds you to reboot; however
wait to reboot until all commands have been entered.
[Device-Name]> set ipaddrtype static
[Device-Name]> set ipaddr <IP Address>
[Device-Name]> set ipsubmask <IP Subnet Mask>
[Device-Name]> set ipgw <Default Gateway IP Address>
[Device-Name]> show ip (to confirm your new settings)
[Device-Name]> reboot 0
7. After the AP reboots, verify the new IP address by reconnecting to
the CLI and enter a show ip command. Alternatively, you can ping
the AP from a network computer to confirm that the new IP
address has taken effect.
8. When the proper IP address is set, use the HTTP interface or CLI
over Telnet to configure the rest of the unit’s operating parameters.

RADIUS Authentication Server
If you enabled RADIUS Authentication on the AP, make sure that your
network’s RADIUS servers are operational. Otherwise, clients will not be
able to log in. There are several reasons the authentication server
services might be unavailable, here are two typical things to check:
• Make sure you have the proper RADIUS authentication server
information setup configured in the AP. Check the RADIUS
Authentication Server’s Shared Secret and Destination Port number
(default is 1812; for RADIUS Accounting, the default is 1813).
• Make sure the RADIUS authentication server RAS setup matches
the AP.
TFTP Server
The “Trivial File Transfer Protocol” (TFTP) server allows you to transfer
files across a network. You can upload configuration files from the AP for
backup or copying, and you can download configuration files or new
software images. The TFTP software is located on the Avaya Wireless
AP Installation CD-ROM.
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, so long as you

have a valid TFTP IP address. Note that you do not need a TFTP server
running unless you want to transfer files to or from the AP.
After the TFTP server is installed:
• Check to see that TFTP is configured to point to the directory
containing the AP Image.
• Make sure you have the proper TFTP server IP Address, the proper
AP Image file name, and that the TFTP server is connected.
• Make sure the TFTP server is configured to both send and

Command Line Interface (CLI) Variations
Command Line Interface (CLI) Variations
Administrators use the CLI to control Access Point operation and monitor
network statistics. The AP supports two types of CLI: the Bootloader CLI
and the normal CLI. The Bootloader CLI provides a limited command set,
and is used when the current AP Image is bad or missing. The Bootloader
CLI allows you to assign an IP Address and download a new image. Once
the image is downloaded and running, the Access Point uses the normal
CLI. This guide covers the normal CLI unless otherwise specified.
Bootloader CLI
The Bootloader CLI is a minimal subset of the normal CLI used to perform
initial configuration of the AP. This interface is only accessible via the
serial interface if the AP does not contain a software image or a download
image command over TFTP has failed.
The Bootloader CLI provides you with the ability to configure the initial
setup parameters as well as download a software image to the device.
The following functions are supported by the Bootloader CLI:
• configuration of initial device parameters using the set command
• show command to view the device’s configuration parameters
• help command to provide additional information on all commands
supported by the Bootloader CLI
• reboot command to reboot the device

Configuring Objects that Require Reboot
Certain objects supported by the Access Point require a device reboot in
order for the changes to take effect. In order to inform the end-user of this
behavior, the CLI provides informational messages when the user has
configured an object that requires a reboot. The following messages are
displayed as a result of the configuring such object or objects.
Example 1: Configuring objects that require the device to be
rebooted
The following message is displayed every time the user has configured
an object that requires the device to be rebooted.
[Device-Name]> set ipaddr 135.114.73.10
The following elements require reboot:
ipaddr
Avaya Wireless AP-8 User’s Guide
A-25
CLI Command Types
Example 2: Executing the “exit”, “quit”, or “done” commands when
an object that requires reboot has been configured
In addition to the above informational message, the CLI also provides a
message as a result of the exit, quit, or done command if changes have
been made to objects that require reboot. If you make changes to objects
that require reboot and execute the exit command the following message
is displayed:
[Device-Name]> exit<CR> OR quit<CR> OR done<CR>
Modifications have been made to parameters that require
the device to be rebooted. These changes will only take
effect after the next reboot.
A-26
Avaya Wireless AP-8 User’s Guide
CLI Command Types
“set” and “show” Command Examples
In general, you will use the CLI show Command to view current
parameter values and use the CLI set Command to change parameter
values. As shown in the following examples, parameters may be set
individually or all parameters for a given table can be set with a single
statement.
Example 1 - Set the Access Point IP Address Parameter
Syntax:
[Device-Name]> set <parameter name> <parameter value>
Example:
[Device-Name]> set ipaddr 10.0.0.12
Result: IP Address will be changed when you reboot the
Access Point. The CLI reminds you when rebooting is required for
a change to take effect. To reboot immediately, enter reboot 0
(zero) at the CLI prompt.
Avaya Wireless AP-8 User’s Guide
A-27
CLI Command Types
Example 2 - Create a table entry or row
Use 0 (zero) as the index to a table when creating an entry. When
creating a table row, only the mandatory table elements are required
(comment is usually an optional table element). For optional table
elements, the default value is generally applied if you do not specify a
value.
Syntax:
[Device-Name]> set <table name> <table index> <element 1>
<value 1> … <element n> <value n>
Example:
[Device-Name]> set mgmtipaccesstbl 0 ipaddr 10.0.0.10
ipmask 255.255.0.0
Result:
A new table entry is created for IP address 10.0.0.10 with a
255.255.0.0 subnet mask.
Example 3 - Modify a table entry or row
Use the index to be modified and the table elements you would like to
modify. For example, suppose the IP Access Table has one entry and you
wanted to modify the IP address:
[Device-Name]> set mgmtipaccesstbl 1 ipaddr 10.0.0.11
A-28
Avaya Wireless AP-8 User’s Guide
CLI Command Types
You can also modify several elements in the table entry. Enter the index
number and specific table elements you would like to modify. (Hint: Use
the search Command to see the elements that belong to the table.)
[Device-Name]> set mgmtipaccesstbl 1 ipaddr 10.0.0.12
ipmask 255.255.255.248 cmt “First Row”
Example 4 - Enable, Disable, or Delete a table entry or row
The following example illustrates how to manage the second entry in a
table.
Syntax:
[Device-Name]> set <Table> index status <enable, disable,
delete>

Using Tables & User Strings
Using Tables & User Strings
Working with Tables
Each table element (or parameter) must be specified, as in the example
below.
[Device-Name]> set mgmtipaccesstbl 0 ipaddr 10.0.0.10 ipmask
255.255.0.0
Below are the rules for creating, modifying, enabling/disabling, and
deleting table entries.
• Creation
— The table name is required.
— The table index is required – for table entry/instance creation
the index is always zero (0).
— The order in which the table arguments or objects are entered
in not important.
— Parameters that are not required can be omitted, in which
case they will be assigned the default value.
A-32
Avaya Wireless AP-8 User’s Guide
Using Tables & User Strings
• Modification
— The table name is required.
— The table index is required – to modify the table, “index” must
be the index of the entry to be modified.
— Only the table objects that are to be modified need to be
specified. Not all the table objects are required.
— If multiple table objects are to be modified the order in which
they are entered is not important.
— If the entire table entry is to be modified, all the table objects
have to be specified.
• Enabling/Disabling
— The table name is required.
— The table index is required – for table enabling/disabling the
index should be the index of the entry to be enabled/disabled.
— The entry’s new state (either “enable” or “disable”) is required.
• Deletion
— The table name is required.
— The table index is required – for table deletion the index
should be the index of the entry to be deleted.
— The word “delete” is required.
Avaya Wireless AP-8 User’s Guide
A-33
Using Tables & User Strings
Using Strings
Since there are several string objects supported by the AP, a string
delimiter is required for the strings to be interpreted correctly by the
command line parser. For this CLI implementation, the single quote or
double quote character can be used at the beginning and at the end of the
string.
For example:
[Device-Name]> set sysname Lobby - Does not need quote marks
[Device-Name]> set sysname “Front Lobby” - Requires quote
marks.
The scenarios supported by this CLI are:
A-34
“My Desk in the
office”
Double Quotes
‘My Desk in the office’
Single Quotes
“My ‘Desk’ in the
office”
Single Quotes within Double Quotes
‘My “Desk” in the
office’
Double Quotes within Single Quotes
“Daniel’s Desk in the
office”
One Single Quote within Double
Quotes
‘Daniel”s Desk in the
office’
One Double Quote within Single
Quotes
Avaya Wireless AP-8 User’s Guide
Configuring the AP using CLI commands
The string delimiter does not have to be used for every string object. The
single quote or double quote only has to be used for string objects that
contain blank space characters. If the string object being used does not
contain blank spaces, then the string delimiters, single or double quotes,
mentioned in this section are not required.
Configuring the AP using CLI commands
Log into the AP using HyperTerminal
1. Open your terminal emulation program (like HyperTerminal) and
set the following connection properties:
— Com Port: <COM1, COM2, etc., depending on your computer>
— Baud rate: 9600
— Data Bits: 8
— Stop bits: 1
— Flow Control: None
— Parity: None
2. Under File -> Properties -> Settings -> ASCII Setup, enable the
Send line ends with line feeds option.
Result: HyperTerminal sends a line return at the end of each line
of code.
3. Enter the CLI password (default is public).

Configuring the AP using CLI commands
NOTE:
Avaya recommends changing your default passwords immediately.
To perform this operation using CLI commands, refer to Change

Log into the AP using Telnet
The CLI commands can be used to access, configure, and manage the
AP using Telnet. Follow these steps:
1. Confirm that your computer’s IP address is in the same IP subnet
as the AP.
NOTE:
If you have not previously configured the Access Point’s IP address
and do not have a DHCP server on the network, the Access Point
will default to an IP address of 169.254.128.132.
2. Go to the DOS command prompt on your computer.
3. Type telnet <IP Address of the unit>.
4. Enter the CLI password (default is public).
NOTE:
Avaya recommends changing your default passwords immediately.

Set Rogue Access Point Detection (RAD) Parameters
The Rogue AP Detection (RAD) feature enables an additional security
level for wireless LAN deployments. The RAD feature provides a
mechanism for detecting Rogue Access Points by utilizing the coverage
of the trusted Access Point deployment.
The Rogue AP Scan employs background scanning using low-level
802.11 scanning functions for effective wireless detection of Access
Points in its coverage area with minimal impact on the normal operation of
the Access Point.
Avaya Wireless AP-8 User’s Guide
A-61
Other Network Settings
The set radstatus command enables Rogue Access Point Detection.
The scan repetition duration (radscanint) is also configurable. If the
Access Point uses directional antennas to provide directional coverage,
then the interface bitmask (radifbitmask) can be configured to maximize
the scanning coverage area.
[Device-Name]> set radstatus enable
[Device-Name]> set radscanint <15-1440>

Radio Specifications
Wireless Communication Range
The range of the wireless signal is related to the composition of objects in
the radio wave path and the transmit rate of the wireless communication.
Communications at a lower transmit range may travel longer distances.
The range values listed in the Communications Range Chart are typical
distances as calculated by Avaya’s development team for FCC-certified
products. These values provide a rule of thumb and may vary according
to the actual radio conditions at the location where the product is used.
The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials. Range is
also impacted due to “obstacles” in the signal path of the radio that may
either absorb or reflect the radio signal.
In Open Office environments, antennas can “see” each other (no physical
obstructions between them). In Semi-open Office environments,
workspace is divided by shoulder-height, hollow wall elements; antennas
are at desktop level. In a Closed Office environment, solid walls and other
obstructions may affect signal strength.
The following tables show typical range values for various environments
for FCC-certified products (range may differ for products certified in other
regulatory domains).
