•Guidelines for Roaming
•Management and Monitoring Capabilities
Introduction to Wireless Networking
An Access Point extends the capability of an existing Ethernet network to devices on a wireless network. Wireless
devices can connect to a single Access Point, or they can move between multiple Access Points located within the same
vicinity. As wireless clients move from one coverage cell to another, they maintain network connectivity.
In a typical network environment (see Figure 1-1), the AP functions as a wireless network access point to data and voice
networks. An AP network provides:
• Seamless client roaming for both data and voice (VoIP)
• Easy installation and operation
• Over-the-air encryption of data
• High speed network links
Figure 1-1 Typical Wireless Network Access Infrastructure
Guidelines for Roaming
• Typical voice network cell coverages vary based on environment. Proxim recommends having a site survey done
professionally to ensure optimal performance. For professional site surveyors, Ekahau™ Site Survey software is
included in the Xtras folder of the Installation CD.
• An AP can only communicate with client devices that support its wireless standards.
• All Access Points must have the same Network Name to support client roaming.
Introduction AP-700 User Guide
Management and Monitoring Capabilities

• 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 Reboot the AP.).
• All Access Points and clients must have matching security settings to communicate.
• The Access Points’ cells should overlap to ensure that there are no gaps in coverage and to ensure that the roaming
client will always have a connection available. To ensure optimal AP placement, Proxim recommends having a site
survey done professionally to ensure optimal performance. For professional site surveyors, Ekahau™ Site Survey
software is included in the Xtras folder of the Installation CD.
• 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.
Management and Monitoring Capabilities
There are several 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
•SSH (Secure Shell) Management
HTTP/HTTPS Interface
The HTTP Interface (Web browser Interface) provides easy access to configuration settings and network statistics from
any computer on the network. You can access the HTTP Interface over your LAN (switch, hub, etc.), over the Internet, or
with a “crossover” Ethernet cable connected directly to your computer’s Ethernet Port.
HTTPS provides an HTTP connection over a Secure Socket Layer. HTTPS is one of three available secure management
options on the AP; the other secure management options are SNMPv3 and SSH. Enabling HTTPS allows the user 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.
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.
You access the CLI over a HyperTerminal serial connection or via Telnet. During initial configuration, you can use the CLI
over a serial port connection to configure an Access Point’s IP address. When accessing the CLI via Telnet, you can
communicate with the Access Point from over your LAN (switch, hub, etc.), from over the Internet, or with a “crossover”
Ethernet cable connected directly to your computer’s Ethernet Port. See Command Line Interface (CLI) for more
information on the CLI and for a list of CLI commands and parameters.

SNMP Management
In addition to the HTTP and the CLI interfaces, you can also manage and configure an AP using the Simple Network
Management Protocol (SNMP). Note that 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
• ORiNOCO Enterprise MIB
Proxim provides these MIB files on the CD-ROM 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. See the
documentation that came with your SNMP manager for instructions on how to compile MIBs.
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. See 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 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.
•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 could learn of notifiable
events and the values of managed objects. 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.
The default SNMPv3 username is administrator, with SHA authentication, and DES privacy protocol.
SSH (Secure Shell) Management
You may securely also manage the AP using SSH (Secure Shell). The AP supports SSH version 2, for secure remote CLI
(Telnet) sessions. SSH provides strong authentication and encryption of session data.
Introduction AP-700 User Guide
Management and Monitoring Capabilities

The SSH server (AP) has host keys - a pair of asymmetric keys - a private key that resides on the AP and a public key
that is distributed to clients that need to connect to the AP. As the client has knowledge of the server host keys, the client
can verify that it is communicating with the correct SSH server.
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 or SSH, see the documentation that came with your
SNMP or SSH program. Also, see the MIB files for information on the parameters available via SNMP and SSH.

AP-700 Hardware Description
Overview
The AP-700 is a tri-mode AP that supports 802.11b, 802.11g, or 802.11a clients. The unit contains one embedded
802.11a/b/g radio that supports the following operational modes:
• 802.11a only mode
• 802.11b only mode
• 802.11g only mode
• 802.11b/g mode
• 802.11g-wifi
NOTE: In countries in which 802.11a (5 GHz) is not available for use, the AP-700 provides dual-band (802.11b and
802.11g) support only. 802.11a functionality covered in this User Guide is not supported.
The AP-700 can be powered through either PoE (802.3af Power-over-Ethernet) or through an external DC power source
using the power cord.
The AP-700 includes a a power jack, a 10/100 base-T Ethernet port, and an RS-232 serial data communication port. See
Figure 2-1. The AP includes an optional security cover that can be installed to protect against access to the power and
LAN cables and to the reset and reload buttons.
Figure 2-1 Rear Panel
The unit has been designed to rest horizontally on a flat surface, but can be wall- or ceiling- mounted with the long axis
vertical. The unit includes screw slots in the bottom plastic for mounting to a flat wall or ceiling.
LED Indicators
The top panel of the AP-700 has the following LED indicators. See Power On the Unit for a description of LED behavior.

Figure 2-2 LED Indicators on the Top Panel
Power-over-Ethernet (PoE)
The AP-700 is equipped with an 802.3af-compliant Power-over-Ethernet (PoE) module. PoE delivers both data and
power to the access point over a single Ethernet cable. If you choose to use PoE, there is no difference in operation; the
only difference is in the power source.
• The PoE integrated module receives ~48 VDC over a standard Category 5 Ethernet cable.
• To use PoE, you must have a 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 supply simultaneously, the Access Point draws power from PoE.
Also see Hardware Installation.
NOTE: The AP’s 802.3af-compliant PoE module is backwards compatible with all ORiNOCO Active Ethernet (PoE) hubs
that do not support the IEEE 802.3af standard.
Antennas
The AP-700 employs two internal antennas for antenna diversity: one is vertically polarized, and the other is horizontally
polarized to provide optimal spatial and polarization diversity. When the AP is hung on the wall of an office or building, the
horizontally polarized antenna provides coverage for that particular floor level. The vertically polarized antenna provides
spatial diversity for the horizontally polarized antenna in the event of an antenna null. In addition, the vertically polarized
antenna provides some coverage above and below the current floor level. When the AP is mounted on the ceiling or
sitting on a table, the effect is the same, but the roles of the two antennas switch.
The AP supports both receive and transmit diversity. When receiving, the AP chooses the antenna that receives the
strongest signal. When transmitting, the AP chooses the antenna with the highest success rate, and broadcasts are
transmitted on alternating antennas.
Antenna diversity is enabled by default (set to “auto”). When using the internal antennas, Proxim recommends leaving
antenna diversity enabled. However, you may disable antenna diversity by manually selecting which antenna to use
through the Command Line Interface. See Configure Antenna Diversity for information.
See External Antennas for information and Install External Antennas (Professional Installation Required) for installation
instructions.

External Antennas
The AP-700 also has two antenna connectors for use with external antennas.
Figure 2-3 AP-700 Antenna Connectors
When the AP is mounted on a wall, connector 1 corresponds to the horizontally polarized internal antenna, providing a
coverage pattern parallel to the wall; connector 2 corresponds to the vertically polarized internal antenna, providing a
coverage pattern parallel to the ceiling/floor. When the AP is mounted to a ceiling, connector 1 corresponds to the
vertically polarized internal antenna, and connector 2 corresponds to the horizontally polarized internal antenna. Plugging
an external antenna in to the antenna connector disables the corresponding internal antenna.
The AP continues to support antenna diversity with external antennas connected. With one external antenna connected
to one of the two antenna connectors on a radio, one internal antenna and one external antenna are used for antenna
diversity. With two external antennas connected, both external antennas are used for antenna diversity, and both internal
antennas are disabled.
With external antennas connected, you may wish to manually select a particular antenna for use. To do so, disable
antenna diversity by manually selecting which antenna to use through the Command Line Interface. See Configure
Antenna Diversity for information.
NOTE: Using two external antennas is not recommended.
For a list of recommended antennas, see http://www.proxim.com/products/wifi/accessories.
For installation instructions, see Install External Antennas (Professional Installation Required).
NOTE:
AP-700 units using external antennas must be installed by a suitably trained professional installation
technician or by a qualified installation service.
See Hardware Installation for AP cabling and mounting instructions, and Install External Antennas
(Professional Installation Required) for external antenna installation instructions.

Mount the AP-700
Proxim recommends that you have a site survey professionally conducted to determine the best location for the AP. For
professional site surveyors, Ekahau Site Survey software is included in the Xtras folder on the Installation CD-ROM.
Note that the AP-700 has been certified under UL Standard 2043 and can be installed in the 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. 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”.
NOTE: When installed in a plenum, the AP must use PoE.
Once you have chosen a final location for your unit, the following are the mounting options are available:
•Wall Mounting
•Ceiling Mounting
Wall Mounting
Follow these steps to mount the unit on a wall:
1. If the unit’s power supply is plugged in, unplug it.
2. Put the mounting plate up to the wall so that the embossed letter “L” is on top (see figure). If the plate is correctly
oriented, the circular tab that is vertically aligned with the square hole should be on top.
3. Fasten the mounting plate with two screws through the circular holes of the plate. Depending on the type of wall, you
may need to use the two fasteners provided.
4. Holding the unit so that the connectors on the rear are facing left, align the two holes on the bottom of the unit with the

Install External Antennas (Professional Installation Required)
Optionally, you can connect two external antennas to your AP.
All products using external antennas must be professionally installed, and the transmit power of the system must be
adjusted by the professional installers to ensure that the system EIRP is in compliance with the limit specified by the
regulatory authority of the country of application.
See the following sections for more information:
•Connecting Antenna(s)
•Adjusting Tx Output Power
•Antenna Types and Maximum Gain
Connecting Antenna(s)
Follow the mounting instructions included with your external antenna, and then connect the antenna cable to the AP, as
follows:
1. Press down near the center of the compartment covering and slide open the external antenna access compartments.

Adjusting Tx Output Power
NOTE: When the system is set to transmit at the maximum power, professional installers must ensure that the maximum
EIRP limit is not exceeded. To achieve this, they may have to add attenuation between the device and the
antenna when a high gain antenna is used.
Use the following formula in combination with the table of EIRP limits in US, Canada, and EU countries to calculate
system transmit power (based on EIRP limits) of these countries:
Tx Power (dBm) = EIRP Limit (dBm) + FL (dB) – G (dB)
where:
Tx Power = Output power measured at the antenna input

Initialization
The following sections detail how to initialize the AP using ScanTool, log in to the HTTP interface, perform an initial
configuration of the AP using the Setup Wizard, and download the required AP software.
•Using ScanTool
•Logging In
•Using the Setup Wizard
•Installing the Software
Using ScanTool
ScanTool is a software utility that is included on the installation CD-ROM. It is an initial configuration tool that 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.
The tool automatically detects the Access Points installed on your network, regardless of IP address, and lets you
configure each unit’s IP settings. In addition, you can use set initial device parameters that will allow the AP to retrieve a
new software to an AP that does not have a valid software image installed (see Client Connection Problems).
To access the HTTP interface and configure the AP, the AP must be assigned an IP address that is valid on its Ethernet
network. By default, the AP is configured to obtain an IP address automatically from a network Dynamic Host
Configuration Protocol (DHCP) server during boot-up. If your network contains a DHCP server, you can run ScanTool to
find out what IP address the AP has been assigned. 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 and initialize the AP:
1. Power up, reboot, or reset the AP.
2. Double-click the ScanTool icon on the Windows desktop to launch the program (if the program is not already
running). If the icon is not on your desktop, click Start > All Programs > ORiNOCO > AP-700 > ScanTool.
NOTE: If your computer has more than one network adapter installed, you will be prompted to select the adapter that
you want ScanTool to use before the Scan List appears. You can use either an Ethernet or wireless adaptor.
If prompted, select an adapter and click OK. You can change your adapter setting at any time by clicking the
Select Adapter button on the Scan List screen.
ScanTool scans the subnet and displays all detected Access Points. The ScanTool’s Scan List screen appears, as
shown in the following example.

Dynamic DNS Support
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 mapping
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.
The system name must be compliant with the encoding rules for host name as per DNS RFC 1123. According to the
encoding rules, the AP name:
• Can contain alphanumeric or hyphen characters only.
• Can contain up to 31 characters.
• Cannot start or end with a hyphen.
• Cannot start with a digit.

Basic IP Parameters
•IP Address Assignment Type: Set this parameter to Dynamic to configure the Access Point as a Dynamic Host
Configuration Protocol (DHCP) client; the Access Point will obtain IP settings from a network DHCP server
automatically during boot-up. If you do not have a DHCP server or if you want to manually configure the Access
Point’s IP settings, set this parameter to Static.
•IP Address: The Access Point’s IP address. When IP Address Assignment Type is set to Dynamic, this field is
read-only and reports the unit’s current IP address. The Access Point will default to 169.254.128.132 if it cannot obtain
an address from a DHCP server.
•Subnet Mask: The Access Point’s subnet mask. When IP Address Assignment Type is set to Dynamic, this field is
read-only and reports the unit’s current subnet mask. The subnet mask will default to 255.255.0.0 if the unit cannot
obtain one from a DHCP server.
•Gateway IP Address: The IP address of the Access Point’s gateway. When IP Address Assignment Type is set to
Dynamic, this field is read-only and reports the IP address of the unit’s gateway. 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.
•Enable DNS Client: Place a check mark in the box provided to enable DNS client functionality. Note that this option
must be enabled before you can configure the other DNS Client parameters.
•DNS Primary Server IP Address: The IP address of the network’s primary DNS server.
•DNS Secondary Server IP Address: The IP address of a second DNS server on the network. The Access Point will
attempt to contact the secondary server if the primary server is unavailable.
•DNS Client Default Domain Name: The default domain name for the Access Point’s network (for example,
“proxim.com”). Contact your network administrator if you need assistance setting this parameter.
Advanced
•Default TTL (Time to Live): Time to Live (TTL) is a field in an IP packet that specifies the number of hops, or routers
in different locations, that the request can travel before returning a failed attempt message. The Access Point uses the
default TTL for generated packets for which the transport layer protocol does not specify a TTL value. This parameter
supports a range from 0 to 255. By default, TTL is 64.
DHCP Server
If your network does not have a DHCP Server, you can configure the AP as a DHCP server to assign dynamic IP
addresses to Ethernet nodes and wireless clients.
CAUTION: Make sure there are no other DHCP servers on the network and do not enable the DHCP server without
checking with your network administrator first, as it could disrupt normal network operation. Also, the AP
must be configured with a static IP address before enabling this feature.
When the DHCP Server functionality is enabled, you can create one or more IP address pools from which to assign
addresses to network devices.

DHCP Relay Agent
When enabled, the DHCP relay agent forwards DHCP requests to the set DHCP server.
Click the Configure > Network > DHCP R A to configure DHCP relay agent servers and enable the DHCP relay agent.
NOTE: At least one DHCP server must be enabled before DHCP Relay Agent can be enabled.
NOTE: If the DHCP relay agent is unable to reach the external DHCP Server specified in the DHCP Server IP Address
Table, the requesting client will receive an IP address from the IP Pool table of the AP’s internal DHCP Server,
even if the internal DHCP Server is disabled.
NOTE: If a client requests an available IP address from the IP Pool table of the AP’s internal DHPC Server, the client will
receive this address, even if the DHCP server on the AP is disabled. To ensure that clients receive IP addresses
only from the DHCP Relay Agent, disable all entries in the IP Pool table of the AP’s internal DHCP server.
The DHCP Relay functionality of the AP supports Option 82 and sends the system name of the AP (as a NAS identifier)
as a sub-option of Option 82.
The AP makes a DHCP Request for lease renewal five minutes ahead of the expiration of the Rebinding time as
specified in the DHCP Offer from the DHCP server obtained during the last renewal.

•802.11b/g mode: This is the default mode. Use this mode if you want to support a mix of 802.11b and 802.11g
devices.
•802.11g-wifi mode: The 802.11g-wifi mode has been defined for Wi-Fi testing purposes. It is not recommended for
use in your wireless network environment.
NOTE: In countries in which 802.11a (5 GHz) is not available for use, the AP-700 provides dual-band (802.11b and
802.11g) support only. 802.11a functionality covered in this User Guide is not supported.
Enable H Band Support
In compliance with FCC regulations, Dynamic Frequency Selection is required in the middle frequency band (M band:
5.25 GHz - 5.25 Ghz) and high frequency band (H band: 5.470 GHz - 5.725 GHz). DFS is enabled automatically when
you use one or both of these frequency bands.
If the AP’s Wireless Card A is variant 2, 3, or 6, the M band channels are enabled by default, and DFS is performed
automatically and cannot be disabled. To add H band channels to the list of available channels, select Enable H Band
Support on the Op Mode page. When the H band is enabled, DFS is enabled automatically, and is performed on both M
and H band channels.
If the AP’s Wireless Card A is variant 8, 10, or 11, both M and H band channels are enabled automatically. DFS is
performed on both M and H band channels and cannot be disabled.
To identify your AP’s software variant, click Monitor > Version to view the Version tab.
For a full discussion of Dynamic Frequency Selection, see Dynamic Frequency Selection/Radar Detection (DFS/RD).
Super Mode and Turbo Mode
Super mode improves throughput between the access point and wireless clients that support this capability. For wireless
clients that support this capability the AP will negotiate and treat them accordingly, for other clients that do not support
super mode, the AP will treat them as normal wireless clients.
Super mode can be configured only when the wireless operational mode is one of the following:
• 802.11a only mode
• 802.11g only mode
• 802.11b/g mode
NOTE: Super mode is not available in 802.11b and 802.11g-wifi operational modes. Turbo mode is available only in
802.11a mode in the FCC regulatory domain. Turbo Mode is not available in frequency bands in which DFS is
required.
Turbo mode is supported in 802.11a mode in the FCC regulatory domain when DFS is not required. Turbo mode supports
turbo speeds at twice the standard data rates, and also dynamically switches between Turbo mode speeds and normal
speeds depending on the wireless client. All connected clients must be using Turbo mode in order for the AP to operate
at Turbo mode speed. If turbo mode is enabled, then this is displayed in the web UI and the transmit speeds and
channels pull-down menus are updated with the valid values.
When Turbo mode is enabled, only a subset of the wireless channels in the 5.0 GHz spectrum can be used. If any
wireless clients do not support turbo mode, the AP will fall back to normal mode.
Turbo mode can be configured only when Super mode has already been enabled.
Super mode is supported in the 2.4 GHz and 5 GHz frequency bands in all regulatory domains. Turbo mode is available
in the 5 GHz frequency band in the FCC regulatory domain when DFS is not required.
IEEE 802.11d Support for Additional Regulatory Domains
The IEEE 802.11d specification allows conforming equipment to operate in more than one regulatory domain over time.
IEEE 802.11d support allows the AP to broadcast its radio’s regulatory domain information in its beacon and probe
responses to clients. This allows clients to passively learn what country they are in and only transmit in the allowable
Advanced Configuration AP-700 User Guide
Interfaces
49
spectrum. When a client enters a regulatory domain, it passively scans to learn at least one valid channel, i.e., a channel
upon which it detects IEEE Standard 802.11 frames.
The beacon frame contains information on the country code, the maximum allowable transmit power, and the channels to
be used for the regulatory domain.
The same information is transmitted in probe response frames in response to a client’s probe requests. Once the client
has acquired the information required to meet the transmit requirements of the regulatory domain, it configures itself for
operation in the regulatory domain.
On some AP models, the regulatory domain and associated parameters are automatically configured when a country is
selected on the System tab. On APs in which country selection is not available on the system tab, the regulatory domain
is pre-programmed into the AP prior to shipment. Depending on the regulatory domain, a default country code is chosen
that is transmitted in the beacon and probe response frames.
Configuring 802.11d Support
Perform the following procedure to enable 802.11d support and select the country code:
1. Click Configure > Interfaces > Operational Mode.
2. Select Enable 802.11d.
3. Select the Country Code from the ISO/IEC 3166-1 CountryCode drop-down menu.
NOTE: On APs with model numbers ending in -WD, this object is not configurable.
4. Click OK.
5. Configure Transmit Power Control and Transmit Power Level if required.
Transmit Power Control/Transmit Power Level
Transmit Power Control uses standard 802.11d frames to control transmit power within an infrastructure BSS (Basic
Service Set, or combination of AP and associated clients that can communicate to each other and/or to the backhaul
connection via the AP). This method of power control is considered to be an interim way of controlling the transmit power
of 802.11d enabled clients in lieu of implementation of 802.11h.
When an AP comes online, it automatically uses the maximum TX power allowed in the regulatory domain. The Transmit
Power Control feature lets the user manually lower the transmit power level by setting a “back-off” value between 0 and
35 dBm.
When Transmit Power Control is enabled, the transmit power level of the card in the AP is set to the maximum transmit
power level minus the back-off value. This power level is advertised in Beacon and Probe Response frames as the
802.11d maximum transmit power level.
When an 802.11d-enabled client learns the regulatory domain related information from Beacon and Probe Response
frames, it learns the power level advertised in Beacon and Probe response frames as the maximum transmit power of the
regulatory domain and configures itself to operate with that power level.
As a result, the transmit power level of the BSS is configured to the power level set in the AP (assuming that the BSS has
only 802.11d enabled clients and an 802.11d enabled AP).
NOTE: In FCC DFS-enabled bands, power control is adjusted from beacon information only.
In addition, ATPC (Automatic Transmit Power Control) is a feature to automatically adapt transmit power when the quality
of the link is more than sufficient to maintain a good communication with reduced transmit power. This feature is required
for FCC DFS. It works by monitoring the quality of the link and reducing the output power of the radio by up to 6 dB when
good link quality can still be achieved. When link quality reduces, the output power is automatically increased up to the
original power level to maintain a good link. For a full discussion of DFS, see Dynamic Frequency Selection/Radar
Detection (DFS/RD).

OFDM stands for Orthogonal Frequency Division Multiplexing; this is the name for the radio technology used by
802.11a/4.9 GHz devices. DSSS stands for Direct Sequence Spread Spectrum; this is the name for the radio
technology used by 802.11b devices.
•MAC Address: This is a read-only field that displays the unique MAC (Media Access Control) address for the Access
Point’s wireless interface. The MAC address is assigned at the factory.
•Regulatory Domain: Reports the regulatory domain for which the AP is certified. Not all features or channels are
available in all countries.
•Network Name (SSID): Enter a Network Name (between 1 and 32 characters long) for the primary wireless network.
You must configure each wireless client using this network to use this name as well. Additional SSIDs and VLANs may
be configured under Configure > SSID/VLAN/Security. Up to 16 SSID/VLANs may be configured.
NOTE: Do not use quotation marks (single or double) in the Network Name; this will cause the AP to misinterpret the
name.
•Enable Auto Channel Select: When the Enable Auto Channel Select option is enabled, the AP scans the area for
other Access Points and selects a free or relatively unused communication channel. This helps prevent interference
problems and increases network performance. By default this feature is enabled. See Dynamic Frequency
Selection/Radar Detection (DFS/RD) for more information and Available Channels for a list of available channels.
•Frequency Channel: When Auto Channel Select is enabled, this field is read-only and displays the Access Point’s
current operating Channel. When Auto Channel Select is disabled, you can specify the Access Point’s operating
channel. If you decide to manually set the unit’s Channel, ensure that nearby devices do not use the same frequency
(unless you are setting up WDS links). Available channels vary based on regulatory domain. See Dynamic Frequency
Selection/Radar Detection (DFS/RD) for more information and Available Channels for a list of available channels.
•Transmit Rate: Use the drop-down menu to select a specific transmit rate for the AP. The values depend on the
Operational mode. Auto Fallback is the default setting; it allows the AP unit to select the best transmit rate based on
the cell size.

•DTIM Period: The Deferred Traffic Indicator Map (DTIM) Period determines when to transmit broadcast and multicast
packets to all clients. If any clients are in power save mode, packets are sent at the end of the DTIM period. This
parameter supports a range between 1 and 255; it is recommended to leave the DTIM at its default value unless
instructed by technical support. Higher values conserve client battery life at the expense of network performance for
broadcast or multicast traffic.
•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.
•Antenna Gain: This parameter modifies the sensitivity of the radio card when detecting radar signals in accordance
with Dynamic Frequency Selection/Radar Detection (DFS/RD) requirements. Given that the radar detection threshold
is fixed by the regulatory codes in the country of operation, and that a variety of antennas with different gains may be
attached to the unit, adjust this threshold to account for higher than expected antenna gains and avoid false radar
detection events. Set this parameter to a value between 0 and 35. The default value is 0.
•Wireless Service Status: Select Shutdown to shutdown the wireless service on a wireless interface, or to Resume
to resume wireless service. See Wireless Service Status for more information.
•Load Balancing Max Clients: Load balancing distributes clients among available access points. Enter a number
between 1 and 63 to specify the maximum number of clients to allow.
•Channel Blacklist Table: The Channel Blacklist table contains all available channels. It can be used to manually
blacklist channels, and it also reflects channels that have been automatically blacklisted by the Dynamic Frequency
Selection/Radar Detection (DFS/RD) function. See Channel Blacklist Table for configuration information.
•Wireless Distribution System: A Wireless Distribution system can be used to establish point-to-point (i.e. wireless
backhaul) connections with other access points. See Wireless Distribution System (WDS) for configuration
information.
Dynamic Frequency Selection/Radar Detection (DFS/RD)
In order to prevent interference with radar systems and other devices that occupy the 5 GHz band, 802.11a APs certified
in the ETSI, TELEC, FCC, and IC regulatory domains (see Affected Countries) and operating in the middle and high
frequency bands select an operating channel through a combination of Auto Channel Select (ACS) and Dynamic
Frequency Selection (DFS)/Radar Detection (RD).
During boot-up, ACS scans the available channels and selects the best channel. Once a channel is selected, the AP
performs a channel availability check for 60 seconds to ensure that the channel is not busy or occupied by radar, and
then commences normal operation. (In Canada, if the channel was previously blacklisted, the AP scans for 600 seconds
before commencing normal operation if the selected channel frequency is in the 5600 - 5650 MHz range). When the AP
enters normal operation, DFS works in the background to detect interference in that channel. If interference is detected,
the AP sends a trap, disassociates all clients, blacklists the channel, and reboots. After it reboots, ACS re-scans and
selects a better channel that is not busy and is free of radar interference.
If ACS is disabled, only channels in the lower, upper, and ISM frequency bands are available for use:
• 36: 5.180 GHz (default)
• 40: 5.200 GHz
• 44: 5.220 GHz
• 48: 5.240 GHz
• 149: 5.745 GHz
• 153: 5.765 GHz
• 157: 5.785 GHz
Advanced Configuration AP-700 User Guide
Interfaces
54
• 161: 5.805 GHz
• 165: 5.825 GHz
If you are using the unit in a country and band that require DFS, 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 the unit select the channel. You may make
channels unavailable by manually “blacklisting” them and preventing those channels being selected, in accordance
with local regulations or interference. You can also display the Channel Blacklist Table to view the channels that have
been blacklisted by the AP.
• In compliance with FCC regulations, the AP uses ATPC (Automatic Transmit Power Control) to automatically adapt
transmit power when the quality of the link is more than sufficient to maintain a good communication with reduced
transmit power. See Transmit Power Control/Transmit Power Level for more information.
DFS is required for three purposes:
1. Radar avoidance both at startup and while operational. To meet these requirements, the AP scans available
frequencies at startup. If a DFS enabled channel is busy or occupied with radar, the system will blacklist the channel
for a period of 30 minutes in accordance with FCC, IC, ETSI, and TELEC regulations. Once fully operational on a
frequency, the AP actively monitors the occupied frequency. If interference is detected, the AP blacklists the channel,
logs a message and rescans to find a new frequency that is not busy and is free of radar interference.
2. Guarantee the efficient use of available frequencies by all devices in a certain area. To meet this requirement, the AP
scans each available frequency upon startup and selects a frequency based upon the least amount of noise and
interference detected. This lets multiple devices operate in the same area with limited interference. This procedure is
done only at startup; if another UNII device comes up on the same frequency, the AP does not detect this or rescan
because of it. It is expected that other devices using these frequencies also are in compliance with country
regulations, so this should not happen.
3. Uniform Channel Spreading. To meet this requirement, the AP randomly selects its operating channel from the
available channels with least interference.
Affected Countries
Japan is certified in the TELEC regulatory domain, Canada is certified in the IC regulatory domain, and the USA is
certified in the FCC regulatory domain for operation in the 5 GHz band.
The following countries are certified in the ETSI regulatory domain for operation in the 5 GHz band:
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.

Advanced Configuration AP-700 User Guide
Interfaces

When RTS/CTS occurs, the sending radio first transmits a Request to Send (RTS) packet to confirm that the medium is
clear. When the receiving radio successfully receives the RTS packet, it transmits back a Clear to Send (CTS) packet to
the sending radio. 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.
Wireless Service Status
The user can shut down (or resume) the wireless service on the wireless interface of the AP through the CLI, HTTP, or
SNMP interface. When the wireless service on a wireless interface is shut down, the AP will:
• Stop the AP services to wireless clients connected on that wireless interface by disassociating them
• Disable the associated BSS ports on that interface
• Disable the transmission and reception of frames on that interface
• Indicate the wireless service shutdown status of the wireless interface through LED and traps
• Enable Ethernet interface so that it can receive a wireless service resume command through CLI/HTTP/SNMP
interface
NOTE: WSS disables BSS ports.
NOTE: The wireless service cannot be shutdown on an interface where Rogue Scan is enabled.
In shutdown state, AP will not transmit and receive frames from the wireless interface and will stop transmitting periodic
beacons. Moreover, none of the frames received from the Ethernet interface will be forwarded to that wireless interface.
Wireless service on a wireless interface of the AP can be resumed through CLI/HTTP/SNMP management interface.
When wireless service on a wireless interface is resumed, the AP will:
• Enable the transmission and reception of frames on that wireless interface
• Enable the associated BSS port on that interface
• Start the AP services to wireless clients
• Indicate the wireless service resume status of the wireless interface through LED and traps
After wireless service resumes, the AP resumes beaconing, transmitting and receiving frames to/from the wireless
interface and bridging the frames between the Ethernet and the wireless interface.
Traps Generated During Wireless Service Shutdown (and Resume)
The following traps are generated during wireless service shutdown and resume, and are also sent to any configured
Syslog server.
When the wireless service is shut down on a wireless interface, the AP generates a trap called
oriTrapWirelessServiceShutdown.
When the wireless service is resumed on a wireless interface, the AP generate a trap called
oriTrapWirelessServiceResumed.
Channel Blacklist Table
The Channel Blacklist table contains all available channels (channels vary based on regulatory domain). It can be used to

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 up to six (6) ports.
In the WDS example below, AP 1 and AP 2 communicate over a WDS link (represented by the blue line). This link
provides Client 2 with access to network resources even though AP 2 is not directly connected to the Ethernet network.
Packets destined for or sent by the client are relayed between the Access Points over the WDS link.
Figure 4-13 WDS Example
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 we only support none or WEP) 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.b/g modes) or 11 Mbits/second (802.11b only
mode), client throughput will decrease when traffic is passing over the WDS link.
• If there is no partner MAC address configured in the WDS table, the WDS port remains disabled.
• A 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.
• If your network does not support spanning tree, be careful to avoid 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, see the Spanning Tree section.

• When WDS is enabled, Spanning Tree protocol is automatically enabled. It may be manually disabled. If Spanning
Tree protocol is enabled by WDS and WDS is subsequently disabled, Spanning tree will remain enabled until it is
manually disabled. See Spanning Tree.
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

Access Point. The AP would ignore commands from any other IP address. In contrast, the IP mask 255.255.255.0
would allow any device that shares the first three octets of the IP address to configure the AP. For example, if you
enter an IP address of 10.20.30.1 with a 255.255.255.0 subnet mask, any IP address between 10.20.30.1 and
10.20.30.254 will have access to the AP’s management interfaces.

the Services tab, and to configure SNMPv3 passwords on the Passwords tab.
SNMP Settings
•SNMP Interface Bitmask: Configure the interface or interfaces (Ethernet, Wireless, All Interfaces) from which you
will manage the AP via SNMP. You can also select Disabled to prevent a user from accessing the AP via SNMP.
HTTP Access
•HTTP Interface Bitmap: Configure the interface or interfaces (Ethernet, Wireless, All Interfaces) from which you
will manage the AP via the Web interface. For example, to allow Web configuration via the Ethernet network only, set
HTTP Interface Bitmask to Ethernet. You can also select Disabled to prevent a user from accessing the AP from the
Web interface.
•HTTP Port: Configure the HTTP port from which you will manage the AP via the Web interface. By default, the HTTP
port is 80. You must reboot the Access Point if you change the HTTP Port.
•HTTP Wizard Status: The Setup Wizard appears automatically the first time you access the HTTP interface. If you
exited out of the Setup Wizard and want to relaunch it, enable this option, click OK, and then close your browser or
reboot the AP. The Setup Wizard will appear the next time you access the HTTP interface.
HTTPS Access (Secure Socket Layer)
NOTE: SSL requires Internet Explorer version 6, 128 bit encryption, Service Pack 1, and patch Q323308.
NOTE: You need to reboot the AP after enabling or disabling SSL for the changes to take effect.
•HTTPS (Secure Web Status): The user can access the AP in a secure fashion using Secure Socket Layer (SSL)
over port 443. The AP comes pre-installed with all required SSL files: default certificate and private key installed. Use
the drop-down menu to enable/disable this feature.
•SSL Certificate Passphrase: After enabling SSL, the only configurable parameter is the SSL passphrase. The
default SSL passphrase is proxim.
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.
If you decide to upload a new certificate and private key (using TFTP or HTTP File Transfer), you need to change the
SSL Certificate Passphrase for the new SSL files.
Accessing the AP through the HTTPS interface
The user should use a SSL intelligent browser to access the AP through the HTTPS interface. After configuring SSL,
access the AP using https:// followed by the AP’s management IP address.

Telnet Configuration Settings
•Telnet Interface Bitmask: Select the interface (Ethernet, Wireless, All Interfaces) from which you can manage the
AP via telnet. This parameter can also be used to Disable telnet management.
•Telnet Port Number: The default port number for Telnet applications is 23. However, you can use this field if you want
to change the Telnet port for security reasons (but your Telnet application also must support the new port number you
select). You must reboot the Access Point if you change the Telnet Port.
•Telnet Login Idle Timeout (seconds): Enter the number of seconds the system will wait for a login attempt. The AP
terminates the session when it times out. The range is 30 to 300 seconds; the default is 60 seconds.
•Telnet Session Idle Timeout (seconds): Enter the number of seconds the system will wait during a session while
there is no activity. The AP will terminate the session on timeout. The range is 60 to 36000 seconds; the default is 900
seconds.
Secure Shell (SSH) Settings
The AP supports SSH version 2, for secure remote CLI (Telnet) sessions. SSH provides strong authentication and
encryption of session data.
The SSH server (AP) has host keys - a pair of asymmetric keys - a private key that resides on the AP and a public key
that is distributed to clients that need to connect to the AP. As the client has knowledge of the server host keys, the client
can verify that it is communicating with the correct SSH server. The client authentication is performed as follows:
• Using a username/password pair if RADIUS Based Management is enabled; otherwise, using a password to
authenticate the user over a secure channel created using SSH.
SSH Session Setup
An SSH session is setup through the following process:
• The SSH server public key is transferred to the client using out-of-band or in-band mechanisms.
• The SSH client verifies the correctness of the server using the server’s public key.
• The user/client authenticates to the server.
• An encrypted data session starts. The maximum number of SSH sessions is limited to two. If there is no activity for a
specified amount of time (the Telnet Session Timeout parameter), the AP will timeout the connection.
SSH Clients
The following SSH clients have been verified to interoperate with the AP’s server. The following table lists the clients,
version number, and the website of the client.
For key generation, OpenSSH client has been verified.
Configuring SSH
Perform the following procedure to set the SSH host key and enable or disable SSH:
1. Click Configure > Management > Services
2. Select the SSH Host Key Status from the drop down menu.
NOTE: SSH Host Key Status can not be changed if SSH status or Secure Management is enabled.
3. To enable/disable SSH, select Enable/Disable from the SSH (Secure Shell) Status drop-down menu.

NOTE: When Secure Management is enabled on the AP, SSH will be enabled by default and cannot be disabled.
Host keys must either be generated externally and uploaded to the AP (see Uploading Externally Generated Host Keys),
generated manually, or auto-generated at the time of SSH initialization if SSH is enabled and no host keys are present.
There is no key present in an AP that is in a factory default state.
To manually generate or delete host keys on the AP:
CAUTION: SSH Host key creation may take 3 to 4 minutes during which time the AP may not respond.
•Select Create to generate a new pair of host keys.
•Select Delete to remove the host keys from the AP. If no host keys are present, the AP will not allows connections
using SSH. When host keys are created or deleted, the AP updates the fingerprint information displayed on the
Management > Services page.
Uploading Externally Generated Host Keys
Perform the following procedure to upload externally generated host keys to the AP. You must upload both the SSH
public key and SSH private key for SSH to work.
1. Verify that the host keys have been externally generated. The OpenSSH client has been verified to interoperate with
AP’s SSH server.

Serial Configuration Settings
The serial port interface on the AP is enabled at all times. See Setting IP Address using Serial Port for information on how
to access the CLI interface via the serial port. You can configure and view the following parameters:
•Serial Baud Rate: Select the serial port speed (bits per second). Choose between 2400, 4800, 9600, 19200, 38400,
or 57600; the default Baud Rate is 9600.
•Serial Flow Control: Select either None (default) or Xon/Xoff (software controlled) data flow control.
NOTE: To avoid potential problems when communicating with the AP through the serial port, Proxim recommends
that you leave the Flow Control setting at None (the default value).
•Serial Data Bits: This is a read-only field and displays the number of data bits used in serial communication (8 data
bits by default).
•Serial Parity: This is a read-only field and displays the number of parity bits used in serial communication (no parity
bits by default).
•Serial Stop Bits: This is a read-only field that displays the number of stop bits used in serial communication (1 stop
bit by default).
NOTE: The serial port bit configuration is commonly referred to as 8N1.
RADIUS Based Management Access
User management of APs can be centralized by using a RADIUS server to store user credentials. The AP cross-checks
credentials using RADIUS protocol and the RADIUS server accepts or rejects the user.
HTTP/HTTPS and Telnet/SSH users can be managed with RADIUS. Serial CLI and SNMP cannot be managed by
RADIUS. Two types of users can be supported using centralized RADIUS management:
•Super User: The super user has access to all functionality of a management interface. A super user is configured in
the RADIUS server by setting the filter ID attribute (returned in the RADIUS Accept packet) for the user to a value of
“super user” (not case sensitive). A user is considered a super user if the value of the filter-id attribute returned in the
RADIUS Accept packet for the user is “super user” (not case sensitive).
•Limited User: A limited user has access to only a limited set of functionality on a management interface. All users
who are not super users are considered limited users. However, a limited user is configured in the RADIUS server by
setting the filter-id attribute (returned in the RADIUS Accept packet) to “limited user” (not case sensitive). Limited
users do not have access to the following configuration capabilities:
– Update/retrieve files to and from APs
– Reset the AP to factory defaults
– Reboot the AP
– Change management properties related to RADIUS, management modes, and management passwords.
NOTE: When a user has both “limited user” and “super user” filter-ids configured in the Radius server, the user has
limited user privileges.
When RADIUS Based Management is enabled, a local user can be configured to provide Telnet, SSH, and HTTP(S)
access to the AP when RADIUS servers fail. The local user has super user capabilities. When secure management is
enabled, the local user can only login using secure means (i.e., SSH or SSL). When the local user option is disabled the
only access to the AP when RADIUS servers are down will be through serial CLI or SNMP.
The Radius Based Management Access parameters allows you to enable HTTP or Telnet Radius Management Access,
to configure a RADIUS Profile for management access control, and to enable or disable local user access, and configure
the local user password. You can configure and view the following parameters:
•HTTP RADIUS Access Control Status: Enable RADIUS management of HTTP/HTTPS users.
•Telnet RADIUS Access Control Status: Enable RADIUS management of Telnet/SSH users.
Advanced Configuration AP-700 User Guide
Management
68
•RADIUS Profile for Management Access Control: Specifies the RADIUS Profile to be used for RADIUS Based
Management Access.
•Local User Status: Enables or disables the local user when RADIUS Based Management is enabled. The default
local user ID is root.
•Local User Password and Confirm Password: The default local user password is public. “Root” cannot be
configured as a valid user for Radius based management access when local user access is enabled.
Automatic Configuration (AutoConfig)
The Automatic Configuration feature which allows an AP to be automatically configured by downloading a specific
configuration file from a TFTP server during the boot up process.
Automatic Configuration is disabled by default. The configuration process for Automatic Configuration varies depending
on whether the AP is configured for dynamic or static IP.
When an AP is configured for dynamic IP, the Configuration filename and the TFTP server IP address are contained in
the DHCP response when the AP gets its IP address dynamically from the DHCP server. When configured for static IP,
these parameters are instead configured in the AP interface.
After setting up automatic configuration you must reboot the AP. When the AP reboots it receives the new configuration
information and must reboot one additional time. If Syslog is configured, a Syslog message will appear indicating the
success or failure of the Automatic Configuration.
Auto Configuration and the CLI Batch File
The Auto Configuration feature allows download of the LTV (Length, Type, Value) format configuration file or the CLI
Batch file. The LTV file contains parameters used by the AP; the CLI Batch file contains CLI executable commands used
to set AP parameters. The AP detects whether the uploaded file is LTV format or a CLI Batch file. If the AP detects an
LTV file, it stores the file in the AP’s flash memory. If the AP detects a CLI Batch file (a file with an extension of .cli), the
AP executes the commands contained in the file immediately. The AP will reboot after executing the CLI Batch file. Auto
Configuration will not result in repeated reboots if the CLI Batch file contains rebootable parameters.
For more information, see the CLI Batch File section.
Set up Automatic Configuration for Static IP
Perform the following procedure to enable and set up Automatic Configuration when you have a static IP address for the
TFTP server.
1. Click Configure > Management > AutoConfig. The Automatic Configuration Screen appears.
2. Check Enable Auto Configuration.
3. Enter the Configuration Filename. The default is config.
4. Enter the IP address of the TFTP server in the TFTP Server Address field. The default is 169.254.128.133.
NOTE: The default filename is “config”. The default TFTP IP address is 169.254.128.133.
5. Click OK to save the changes.
6. Reboot the AP. When the AP reboots it receives the new configuration information and must reboot one additional
time. If a Syslog server was configured, the following messages can be observed on the Syslog server:
• AutoConfig for Static IP
• TFTP server address and configuration filename
• AutoConfig Successful

Set up Automatic Configuration for Dynamic IP
Perform the following procedure to enable and set up Automatic Configuration when you have a dynamic IP address for
the TFTP server via DHCP.
The Configuration filename and the TFTP server IP address are contained in the DHCP response when the AP gets its IP
address dynamically from the DHCP server. A Syslog server address is also contained in the DHCP response, allowing
the AP to send Auto Configuration success and failure messages to a Syslog server.
NOTE: The configuration filename and TFTP server IP address are configured only when the AP is configured for Static
IP. If the AP is configured for Dynamic IP these parameters are not used and obtained from DHCP.
1. Click Configure > Management > AutoConfig.
The Automatic Configuration screen appears.
2. Check Enable Auto Configuration.

Hardware Configuration Reset (CHRD)
Hardware Configuration Reset Status is a parameter that defines the hardware configuration reset behavior of the AP.
If a user loses or forgets the AP’s HTTP/Telnet/SNMP password, the Reload button on the power injector provides a way
to reset the AP to default configuration values and gain access to the AP. However, in AP deployments where physical
Advanced Configuration AP-700 User Guide
Management
71
access to the AP is not protected, an unauthorized person could reset the AP to factory defaults and thus gain control of
the AP. The user can disable the hardware configuration reset functionality to prevent unauthorized access.
The hardware configuration reset feature operates as follows:
• When hardware configuration reset is enabled, the user can press the Reload button on the power injector for 10
seconds when the AP is in normal operational mode in order to delete the AP configuration.
• When hardware configuration reset is disabled, pressing the Reload button when the AP is in normal operational
mode does not have any effect on the AP.
• The hardware configuration reset parameter does not have any effect on the functionality of the reload button to
delete the AP image during AP boot loader execution.
• The default hardware configuration reset status is enabled. When disabling hardware configuration reset, the user is
recommended to configure a configuration reset password. A configuration reset option appears on the serial port
during boot up, before the AP reads its configuration and initializes.
• Whenever the AP is reset to factory default configuration, hardware configuration reset status is enabled and the
configuration reset password is set to the default, “public”.
• If secure mode is enabled in the AP, only secure (SSL, SNMPv3, SSH) users can modify the values of the Hardware
Configuration Reset Status and the configuration reset password.
Configuration Reset via Serial Port During Bootup
If hardware configuration reset is disabled, the user gets prompted by a configuration reset option to reset the AP to
factory defaults during boot up from the serial interface. By pressing a key sequence (ctrl-R), the user gets prompted to
enter a configuration reset password before the configuration is reset.
NOTE: It is important to safely store the configuration reset password. If a user forgets the configuration reset password,
the user will be unable to reset the AP to factory default configuration if the AP becomes inaccessible and the
hardware configuration reset functionality is disable.
Configuring Hardware Configuration Reset
Perform the following procedure to configure Hardware Configuration Reset and to set the Configuration Reset
Password. See Figure 4-22.
1. Click Configure > Management > CHRD.

3. Change the default Configuration Reset Password in the “Configuration Reset Password” and “Confirm” fields.
4. Click OK.
5. Reboot the AP.
NOTE: It is important to safely store the configuration reset password. If a user forgets the configuration reset password,
the user will be unable to reset the AP to factory default configuration if the AP becomes inaccessible and the
hardware configuration reset functionality is disable.
Procedure to Reset Configuration via the Serial Interface
1. During boot up, observe the message output on the serial interface.
The AP prompts the user with the message: “Press ctrl-R in 3 seconds to choose configuration reset option.”
2. Enter ctrl-R within 3 seconds after being prompted.
The AP prompts the user with “Press ctrl-Z to continue with normal boot up or enter password to reset configuration.”
If the user enters ctrl-Z, the AP continues to boot with the stored configuration.
3. Enter the configuration reset password. The default configuration reset password is “public”.
When the correct configuration reset password is entered, the AP gets reset to factory defaults and displays the
message “AP has been reset to Factory Default Settings.” The AP continues to boot up. If an incorrect configuration
reset password is entered, the AP shows an error message and reprompts the user. If the incorrect password is
entered three times in a row, the AP proceeds to boot up.

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.
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.
Advanced Configuration AP-700 User Guide
Filtering
75
Figure 4-26 Static MAC Filter Configuration
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).)
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.
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).
When creating a filter, you can configure the Wired parameters only, the Wireless parameters only, or both sets of
parameters. Which parameters to configure depends upon the traffic that you want block:
• To prevent all traffic from a specific wired MAC address from being forwarded to the wireless network, configure only
the Wired MAC Address and Wired Mask (leave the Wireless MAC Address and Wireless Mask set to all zeros).
• To prevent all traffic from a specific wireless MAC address from being forwarded to the wired network, configure only
the Wireless MAC address and Wireless Mask (leave the Wired MAC Address and Wired Mask set to all zeros).
• To block traffic between a specific wired MAC address and a specific wireless MAC address, configure all four
parameters.

Consider a network that contains a wired server and three wireless clients. The MAC address for each unit is as follows:
• Wired Server: 00:40:F4:1C:DB:6A
• Wireless Client 1: 00:02:2D:51:94:E4
• Wireless Client 2: 00:02:2D:51:32:12

Prevent Two Specific Devices from Communicating
Configure the following settings to prevent the Wired Server and Wireless Client 1 from communicating:
•Wired MAC Address: 00:40:F4:1C:DB:6A
•Wired Mask: FF:FF:FF:FF:FF:FF
•Wireless MAC Address: 00:02:2D:51:94:E4
•Wireless Mask: FF:FF:FF:FF:FF:FF
Result: Traffic between the Wired Server and Wireless Client 1 is blocked. Wireless Clients 2 and 3 can still communicate
with the Wired Server.
Prevent Multiple Wireless Devices from Communicating with a Single Wired Device
Configure the following settings to prevent Wireless Clients 1 and 2 from communicating with the Wired Server:
•Wired MAC Address: 00:40:F4:1C:DB:6A
•Wired Mask: FF:FF:FF:FF:FF:FF
•Wireless MAC Address: 00:02:2D:51:94:E4
•Wireless Mask: FF:FF:FF:00:00:00
Result: When a logical “AND” is performed on the Wireless MAC Address and Wireless Mask, the result corresponds to
any MAC address beginning with the 00:20:2D prefix. Since Wireless Client 1 and Wireless Client 2 share the same
prefix (00:02:2D), traffic between the Wired Server and Wireless Clients 1 and 2 is blocked. Wireless Client 3 can still
communicate with the Wired Server since it has a different prefix (00:20:A6).

Prevent Messages Destined for a Specific Multicast Group from Being Forwarded to the Wireless LAN
If there are devices on your Ethernet network that use multicast packets to communicate and these packets are not
required by your wireless clients, you can set up a Static MAC filter to preserve wireless bandwidth. For example, if
routers on your network use a specific multicast address (such as 01:00:5E:00:32:4B) to exchange information, you can
set up a filter to prevent these multicast packets from being forwarded to the wireless network:
•Wired MAC Address: 01:00:5E:00:32:4B
•Wired Mask: FF:FF:FF:FF:FF:FF
•Wireless MAC Address: 00:00:00:00:00:00
•Wireless Mask: 00:00:00:00:00:00
Result: The Access Point does not forward any packets that have a destination address of 01:00:5E:00:32:4B to the
wireless network.

TCP/UDP Port
Port-based filtering enables you to control wireless user access to network services by selectively blocking TCP/UDP
protocols through the AP. A user specifies a Protocol Name, Port Number, Port Type (TCP, UDP, or TCP/UDP), and
filtering interfaces (Wireless only, Ethernet only, a combination of Wireless and Ethernet, or all interfaces) in order to

Rogue Scan
The Rogue Scan feature provides an additional security level for wireless LAN deployments. Rogue Scan uses the
selected wireless interface(s) for scanning its coverage area for Access Points and clients.
A centralized Network Manager receives MAC address information from the AP on all wireless clients detected by the AP.
The Network Manager then queries all wired switches to find out the inbound switch/port of these wireless clients. If the
switch/port does not have a valid Access Point connected to it as per a pre-configured database, the Network Manager
proceeds to block that switch/port and prevent the Rogue AP from connecting to the wired network.
Figure 4-34 Preventing Rogue AP Attacks
The figure above shows Client 1 connected to a Trusted AP and Client 2 connected to a Rogue AP. The Trusted AP
scans the networks, detects Client 2, and notifies the Network Manager. The Network Manager uses SNMP/CLI to query
the wired switch to find the inbound switch port of Client 2’s packets. The Network Manager verifies that this switch/router

and port does not have a valid Access Point as per the administrator’s database. Thus it labels Client 2’s AP as a Rogue
AP and proceeds to prevent the Rogue AP attack by blocking this switch’s port.
APs can be detected either by active scanning using 802.11 probe request frames or passively by detecting periodic
beacons, or both. Wireless clients are detected by monitoring 802.11 connection establishment messages such as
association/authentication messages or data traffic to or from the wireless clients.
There are two scanning modes available per wireless interface: continuous scanning mode and background scanning
mode.
Continuous Scanning Mode
The continuous scanning mode is a dedicated scanning mode where the wireless interface performs scanning alone and
does not perform the normal AP operation of servicing client traffic.
In continuous scanning mode the AP scans each channel for a channel scan time of one second and then moves to the
next channel in the scan channel list. With a channel scan time of one second, the scan cycle time will take less than a
minute (one second per channel). Once the entire scan channel list has been scanned the AP restarts scanning from the
beginning of the scan channel list.
Background Scanning Mode
In background scanning mode the AP performs background scanning while performing normal AP operations on the
wireless interface.
You can configure the scan cycle time between 1-1440 minutes (24 hours). The scan cycle time indicates how
frequently a channel is sampled and defines the minimum attack period that can go unnoticed.
In background scanning mode the AP will scan one channel then wait for a time known as channel scan time. The
channel scan time affects the amount of data collected during scanning and defines the maximum number of samples
(possible detections) in one scan. This is increased to improve scanning efficiency; the tradeoff is that it decreases
throughput. The optimum value for this parameter during background scanning mode is 20ms.The channel scan time is
calculated from the scan cycle time parameter and the number of channels in the scan channel list as follows:
intra-channel scan time = (scan cycle time - (channel scan time * number of channels in the scan list))/number of
channels in the scan list.
Rogue Scan Data Collection
The AP stores information gathered about detected stations during scanning in a Rogue Scan result table. The Rogue
Scan result table can store a maximum of 2000 entries. When the table fills, the oldest entry gets overwritten. The Rogue
Scan result table lists the following information about each detected station:
• Station Type: indicates one of the following types of station:
– Unknown station
– AP station
– Infrastructure Client Station
– IBSS Client Station
• MAC Address of the detected station
• Channel: the working channel of the detected station
• SNR: the SNR value of the last frame from the station as received by the AP
• BSSID: the BSSID field stores the:
– MAC address of the associated Access Point in the case of a client.
– Zero MAC address or MAC address of the partner Access Point if the AP is a partner of a WDS link
The AP ages out older entries in the Rogue Scan result table if a detected station is inactive for more than the Scan
Result Table Ageing Time.

Perform this procedure to enable Rogue Scan and define the Scan Interval and Scan Interface. See Figure 4-35.
The Rogue Scan screen also displays the number of new access points and clients detected in the last scan on each
wireless interface.
1. Enable the Security Alarm Group. Select the Security Alarm Group link from the Rogue Scan screen. Configure a
Trap Host to receive the list of access points (and clients) detected during the scan.
2. Click Configure > Alarms > Rogue Scan.
3. Enable Rogue Scan by checking Enable Rogue Scan.
NOTE: Rogue Scan cannot be enabled on a wireless interface when the Wireless Service Status on that interface is
shutdown. First, resume service on the wireless interface.
NOTE: Enabling Rogue Scan simultaneously with Broadcast Unique Beacon will cause a drift in the beacon interval
and the occasional missing of beacons.
4. Enter the Scan Mode. Select Background Scanning or Continuous Scanning. In Continuous Scanning mode the AP
stops normal operation and scans continuously on that interface. In Background Scanning mode, the AP performs
background scanning while doing normal AP operation on that interface.
5. If the Scan Mode is Background Scanning, then enter the Scan Interval.
• The Scan Interval specifies the time period in minutes between scans in Background Scanning mode and can be
set to any value between 1 and 1440 minutes.
6. Configure the Scan Result Table Ageing Time. The AP ages out older entries in the Rogue Scan result table if a
detected station is inactive for more than this time. The valid range is from 60-7200 minutes, the default is 60 minutes.
7. Configure the Scan Results Trap Notification Mode to control the notification behavior when APs or stations are
detected in a scan:
• No Notification
•Notify AP
• Notify Client
• Notify All (Notify both AP and Client detection)
8. Configure the Scan Results Trap Report Style to control the way detected stations are reported in the notification:
• Report all detected stations since last scan (default)
• Report all detected stations since start of scan

Bridge
93
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-tabs:
•Spanning Tree
•Intra BSS
•Packet Forwarding
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. Proxim recommends that you leave these parameters at their default
values unless you are familiar with the Spanning Tree protocol.
NOTE: Spanning Tree protocol is disabled by default. When WDS is enabled, Spanning Tree protocol is automatically
enabled. It may be manually disabled. If Spanning Tree protocol is enabled by WDS and WDS is subsequently
disabled, Spanning tree will remain enabled until it is manually disabled.

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 interface.
The Storm Threshold parameters allow you to specify a set of thresholds for each interface of the AP, identifying separate
values for the number of broadcast messages/second and Multicast messages/second.
When the number of frames for an interface or from a single network device exceeds the maximum value per second, the
AP will ignore all subsequent messages in that second received on that interface or from that network device.
•Address Threshold: Enter the maximum allowed number of packets per second.
•Ethernet Threshold: Enter the maximum allowed number of packets per second.
Advanced Configuration AP-700 User Guide
Bridge
95
•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.
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.
Configuring Interfaces for Packet Forwarding
Configure your AP to forward packets by specifying port(s) to which packets are redirected and a destination MAC
address.
1. Within the Packet Forwarding Configuration screen, check the box labeled Enable Packet Forwarding.
2. Specify a destination Packet Forwarding MAC Address. The AP will redirect all unicast, multicast, and broadcast
packets received from wireless clients to the address you specify.
3. Select a Packet Forwarding Interface Port from the drop-down menu. You can redirect traffic to:
– Ethernet
– A WDS connection (see Wireless Distribution System (WDS) for details)
– Any (traffic is redirected to a port based on the bridge learning process)

QoS
Wi-Fi Multimedia (WMM)/Quality of Service (QoS) Introduction
The AP supports Wi-Fi Multimedia (WMM), which is a solution for QoS functionality based on the IEEE 802.11e
specification. WMM defines enhancements to the MAC for wireless LAN applications with Quality of Service
requirements, which include transport of voice traffic over IEEE 802.11 wireless LANs.
The enhancement are in the form of changes in protocol frame formats (addition of new fields and information elements),
addition of new messages, definition of new protocol actions, channel access mechanisms (differentiated control of
access to medium) and network elements (QoS/WME aware APs, STAs), and configuration management.
WME supports Enhanced Distributed Channel Access (EDCA) for prioritized QoS services. The WME/QoS feature can
be enabled or disabled per wireless interface. For more information on QoS, see “Technical Bulletin 69504 Revision 2” at
<http://keygen.proxim.com/support/orinoco/tb/tb69504_3wmm.pdf>.

Enhanced Distributed Channel Access (EDCA)
WME uses Enhanced Distributed Channel Access, a prioritized CSMA/CA access mechanism used by WME-enabled
clients/AP in a WME enabled BSS to realize different classes of differentiated Channel Access.
A wireless Entity is defined as all wireless clients and APs in the wireless medium contending for the common wireless
medium. EDCA uses a separate channel access function for each of the Access Categories (Index) within a wireless
entity. Each channel access function in a wireless entity that contends for the wireless medium as if it were a separate
client contending for the wireless medium. Different channel access functions in a given Wireless Entity contend among
themselves for access to the wireless medium in addition to contending with other clients.
STA EDCA Table and AP EDCA Table
This page is used to configure the client (STA) and AP Enhanced Distributed Channel Access (EDCA) parameters. You
can modify the EDCA values.
The EDCA parameter set provides information needed by the client stations for proper QoS operation during the wireless
contention period. These parameters are used by the QoS enabled AP to establish policy, to change policies when
accepting new stations or new traffic, or to adapt to changes in the offered load. The EDCA parameters assign priorities
to traffic types where higher priority packets gain access to the wireless medium more frequently than lower priority
packets.
NOTE: Default recommended values for EDCA parameters have been defined; Proxim recommends not modifying
EDCA parameters unless strictly necessary.

Radius Profiles
102
Radius Profiles
Configuring Radius Profiles on the AP allows the administrator to define a profile for RADIUS Servers used by the system
or by a VLAN. The network administrator can define RADIUS Servers per Authentication Mode and per VLAN.
The AP communicates with the RADIUS server defined in a profile to provide the following features:
•MAC Access Control Via RADIUS Authentication
•802.1x Authentication using RADIUS
•RADIUS Accounting
Also, RADIUS Based Management Access allows centralized user management.
The network administrator can configure default RADIUS authentication servers to be used on a system-wide basis, or in
networks with VLANs enabled the administrator can also configure separate authentication servers to be used for MAC
authentication, EAP authentication, or Accounting in each VLAN. You can configure the AP to communicate with up to six
different RADIUS servers per VLAN/SSID:
• 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)
• Primary Accounting Server
• Back-up 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.
RADIUS Servers per Authentication Mode and per VLAN
The user can configure separate RADIUS authentication servers for each authentication mode and for each SSID
(VLAN). For example:
• The user can configure separate RADIUS servers for RADIUS MAC authentication and 802.1x authentication
• The user can configure separate RADIUS servers for each VLAN: VLAN1 could support only WEP clients, whereas
VLAN2 could support 802.1x and WEP clients.
Figure 4-42 RADIUS Servers per VLAN
Advanced Configuration AP-700 User Guide
Radius Profiles
103
This figure shows a network with separate authentication servers for each authentication type and for each VLAN. The
clients in VLAN 1 are authenticated using the authentication servers configured for VLAN 1. The type of authentication
server used depends on whether the authentication is done for an 802.1x client or a non-802.1x client. The clients in
VLAN 2 are authenticated using a different set of authentication servers configured for authenticating users in VLAN 2.
Authentication servers for each VLAN are configured as part of the configuration options for that VLAN. RADIUS profiles
are independent of VLANs. The user can define any profile to be the default and associate all VLANs to that profile. Four
profiles are created by default, “MAC Authentication”, “EAP Authentication”, Accounting”, and “Management”.
RADIUS Servers Enforcing VLAN Access Control
A RADIUS server can be used to enforce VLAN access control in two ways:
• Authorize the SSID the client uses to connect to the AP. The SSID determines the VLAN that the client gets assigned
to.
• Assigning the user to a VLAN by specifying the VLAN membership information of the user.
Configuring Radius Profiles
A RADIUS server Profile consists of a Primary and a Secondary RADIUS server that get assigned to act as either MAC
Authentication servers, 802.1x/EAP Authentication servers, or Accounting Servers in the VLAN Configuration. See
Configuring Security Profiles.
The RADIUS Profiles tab allows you to add new RADIUS profiles or modify or delete existing profiles.

and the password sent to the RADIUS server is the shared secret (configured below).
– Colon delimited/SS: MAC addresses are formatted with a colon between each pair of digits (xx:yy:zz:aa:bb:cc)
and the password sent to the RADIUS server is the shared secret (configured below).
– Single dash delimited/SS: MAC addresses are formatted with a dash between the sixth and seventh digits
(xxyyzz-aabbcc) and the password sent to the RADIUS server is the shared secret (configured below).
– No delimiters/SS: MAC addresses are formatted with no characters or spaces between pairs of hexadecimal
digits (xxyyzzaabbcc) and the password sent to the RADIUS server is the shared secret (configured below).
– Dash delimited/MAC: MAC addresses are formatted with a dash between each pair of digits (xx-yy-zz-aa-bb),
and the password sent to the RADIUS server is the MAC address of the client.

3. Click OK.
4. Select the Profile and click Edit to configure the Secondary RADIUS Server, if required.
MAC Access Control Via 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. You can define a RADIUS Profile
that specifies the IP Address of the server that contains a central list of MAC Address values identifying 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.
NOTE: Each VLAN can be configured to use a separate RADIUS server (and backup server) for MAC authentication.
MAC access control can be separately enabled for each VLAN.
NOTE: Contact your RADIUS server manufacturer if you have problems configuring the server or have problems using
RADIUS authentication.
802.1x Authentication using RADIUS
You must configure a primary EAP/802.1x Authentication server to use 802.1x security. A back-up server is optional.
NOTE: Each VLAN can be configured to use a separate RADIUS server (and backup server) for 802.1x authentication.
802.1x authentication (“EAP authentication”) can be separately enabled for each VLAN.
Advanced Configuration AP-700 User Guide
Radius Profiles
106
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.
NOTE: Each VLAN can be configured to use a separate RADIUS accounting server (and backup accounting 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.
• Idle-Timeout or Session-Timeout attributes are configured in the Radius server.
If the client roams from one AP to another, one session is terminated and a new session is begun.
NOTE: This feature requires RADIUS authentication using MAC Access Control or 802.1x. Wireless clients configured in
the Access Point’s static MAC Access Control list are not tracked.
Authentication and Accounting Attributes
Additionally, the AP supports a number of Authentication and Accounting Attributes defined in RFC2865, RFC2866,
RFC2869, and RFC3580.
Authentication Attributes
• State: Received in Access-Accept Packet by the AP during Authentication and sent back as-is during
Re-Authentication.
• Class: Received in Access-Accept Packet by the AP during Authentication and back as in Accounting Packets.
• Session-Timeout
– If the RADIUS server does not send a Session-Timeout, the AP will set the subscriber expiration time to 0, which
means indefinite access.
– The Termination Action attribute defines how the Session-Timeout attribute will be interpreted. If the Termination
Action is DEFAULT, then the session is terminated on expiration of the Session-Timeout time interval. If
Termination Action is RADIUS-Request, then re-authentication is done on expiration on the session.
– If the RADIUS server sends a Session-Timeout, the value specified by the Session-Timeout attribute will take
precedence over the configured Authorization Lifetime value.
• Termination-Action
– Valid values are: Default (0), RADIUS-Request (1). When the value is “default,” the Termination-Action attribute
sends an accounting stop message and then reauthenticates. If the value is “RADIUS-Request,” the
Termination-Action attribute reauthenticates without sending an accounting stop.
• Idle Timeout
– The AP internally maintains the Idle-Timeout attribute obtained for each of the users during their authentication
process, and uses this time interval in place of accounting inactivity time for timing out clients.
• Calling Station Id
– MAC address of the client being authenticated.
• Called Station Id
– The AP sends the MAC address of its own wireless interface with which the client getting authenticated is getting
associated, appended with the SSID. If VLAN is enabled, the SSID and corresponding VLAN ID get appended.
• Acct-Interim-Interval
Advanced Configuration AP-700 User Guide
Radius Profiles
107
– Obtained during the Authentication process and used for determining the time interval for sending Accounting
Update messages.
– This attribute value takes precedence over the value of the Accounting Update Interval.
Accounting Attributes
• Acct-Delay-Time
– Indicates how many seconds the AP has been trying to send a particular packet related to a particular user. This
time can be used at the server to determine the approximate time of the event generating this accounting request.
• Acct-Session-Id
– Unique accounting ID that aids in tracking client accounting records. This attribute is sent in Start and Stop
RADIUS accounting messages, and contains the client MAC address appended with the unique session ID.
•Acct-Session-Time
– Acct-Session-Time is calculated the following way (for each transmitted/retransmitted Acct-Stop):
Acct-Session-Time = time of last sent packet - subscriber login time.
• Acct-Input-Octets
– Number of octets (bytes) received by subscriber.
• Acct-Output-Octets
– Number of octets (bytes) sent by subscriber.
• Acct-Input-Packets
– Number of packets received by subscriber.
• Acct-Output-Packets
– Number of packets sent by subscriber.
• Acct-Terminate Cause
– Indicates how the session was terminated.
• Vendor Specific Attributes

SSID/VLAN/Security
108
SSID/VLAN/Security
The AP provides several security features to protect your network from unauthorized access. This section gives an
overview of VLANs and then discusses the SSID/VLAN/Security configuration options in the AP:
•VLAN Overview
•Management VLAN
•Security Profile
•MAC Access
•Wireless
The AP also provides Broadcast Unique Beacon/Closed System and Rogue Scan to protect your network from
unauthorized access. See the Wireless and Rogue Scan sections from more information.
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
– 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.
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security
109
Figure 4-45 Components of a Typical VLAN
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,
a 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 SSIDs per radio, with
a unique VLAN configurable per SSID.
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.
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.
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, based on an SSID/VLAN grouping (also referred
as a VLAN Workgroup or a Sub-network).
The primary scenarios for using VLAN workgroups are as follows:
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security
110
1. VLAN disabled: Your network does not use VLANs, and you cannot configure the AP to use multiple SSIDs.
2. VLAN enabled, each VLAN workgroup uses a different VLAN ID Tag.
3. VLAN enabled, a mixture of Tagged and Untagged workgroups exist.
4. VLAN enabled, all VLANs untagged: VLAN is enabled in order to use SSID. (Note that typical use of SSIDs assumes
actual use of VLANs.)
NOTE: VLAN must be enabled to configure security per SSID.
Management VLAN
Figure 4-46 Mgmt VLAN
VLAN Tagging Management
Control Access to the AP
Management access to the AP can easily be secured by making 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.
NOTE: When VLAN is enabled, ensure that all devices in the network share the same VLAN ID.
1. Click Configure > SSID/VLAN/Security > Mgmt VLAN.
2. Set the VLAN Management ID to a value of between 1 and 4094. (A value of -1 disables VLAN Tagging).
3. Place a check mark in the Enable VLAN Tagging box.
Provide Access to a Wireless Host in the Same Workgroup
The VLAN feature can allow wireless clients to manage the AP. If the VLAN Management ID matches a VLAN User ID,
then those wireless clients who are members of that VLAN will have AP management access.
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security
111
CAUTION: Once a VLAN Management ID is configured and is equivalent to one of the VLAN User IDs on the AP, all
members of that User VLAN will have management access to the AP. Be careful to restrict VLAN
membership to those with legitimate access to the AP.
NOTE: When VLAN is enabled, ensure that all devices in the network share the same VLAN ID.
1. Click Configure > SSID/VLAN/Security > Mgmt VLAN.
2. Set the VLAN Management ID to use the same VLAN ID as one of the configured SSIDs.
3. Place a check mark in the Enable VLAN Tagging box.
Disable VLAN Tagging
1. Click Configure > SSID/VLAN/Security > Mgmt VLAN.
2. Remove the check mark from the Enable VLAN Tagging box (to disable all VLAN functionality) or set the VLAN
Management ID to -1 (to disable VLAN Tagging only).
NOTE: If you disable VLAN Tagging, you will be unable to configure security per SSID.
Security Profile
See the following sections:
•Security Features
•Authentication Protocol Hierarchy
•VLANs and Security Profiles
•Configuring Security Profiles
Security Features
The AP supports the following security features:
•WEP Encryption: The original encryption technique specified by the IEEE 802.11 standard.
•802.1x Authentication: An IEEE standard for client authentication.
•Wi-Fi Protected Access (WPA/802.11i [WPA2]): A new standard that provides improved encryption security over WEP.
NOTE: The AP does not support shared key 802.11 MAC level authentication. Clients with this MAC level feature must
disable it.
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.
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.
Popular EAP types include:
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security
112
• EAP-Message Digest 5 (MD5): Username/Password-based authentication; does not support automatic key
distribution
• EAP-Transport Layer Security (TLS): Certificate-based authentication (a certificate is required on the server and each
client); supports automatic key distribution
• EAP-Tunneled Transport Layer Security (TTLS): Certificate-based authentication (a certificate is required on the
server; a client’s username/password is tunneled to the server over a secure connection); supports automatic key
distribution
• PEAP - Protected EAP with MS-CHAP: Secure username/password-based authentication; supports automatic key
distribution
Different servers support different EAP types and each EAP type provides different features. See the documentation that
came with your RADIUS server to determine which EAP types it supports.
NOTE: The AP supports the following EAP types when Security Mode is set to 802.1x, WPA, or 802.11i (WPA2):
EAP-TLS, PEAP, EAP-TTLS, EAP-MD5, and EAP-SIM.
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 the Security Mode is set to 802.1x Station, WPA Station, or 802.11i Station you need to configure your RADIUS
server for authentication purposes.
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 4-47 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).
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.
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security

Wi-Fi Protected Access (WPA/802.11i [WPA2])
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). The AP supports 802.11i (WPA2), based on the IEEE 802.11i security
standard.
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
• Client/server mutual authentication
–802.1x
– Pre-shared key (for networks that do not have an 802.1x solution implemented)
The AP supports the following WPA security modes:
•WPA: The AP uses 802.1x to authenticate clients and TKIP for encryption. 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 or 32
alphanumeric characters. The AP also supports a PSK Pass Phrase option to facilitate the creation of the TKIP
Pre-Shared Key (so a user can enter an easy-to-remember phrase rather than a string of characters).
•802.11i (also known as WPA2): The AP provides security to clients according to the 802.11i draft standard, using
802.1x authentication, a CCMP cipher based on AES, and re-keying.
•802.11i-PSK (also known as WPA2 PSK): The AP uses a CCMP cipher based on AES, and encrypts frames to clients
based on a Pre-Shared Key. The Pre-Shared Key must be 256 bits long, which is either 64 hexadecimal digits or 32
alphanumeric characters. 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).
NOTE: For more information on WPA, see the Wi-Fi Alliance Web site at http://www.wi-fi.org.
Authentication Protocol Hierarchy
There is a hierarchy of authentication protocols defined for the AP. The hierarchy is as follows, from highest to lowest:
• 802.1x authentication (including 802.1x, WPA, WPA-PSK, 802.11i, 802.11i-PSK)
• MAC Access Control via RADIUS Authentication
• MAC Access Control through individual APs' MAC Access Control Lists
Advanced Configuration AP-700 User Guide
SSID/VLAN/Security
114
If you have both 802.1x and MAC Access Control authentication enabled, the 802.1x authentication takes precedence
because it is higher in the authentication protocol hierarchy. This is required in order to propagate the WEP/TKIP/AES
keys to the clients in such cases. If you disable 802.1x on the AP, you will see the effects of MAC authentication.
In addition, setting MAC Access Control status to Strict will cause both MAC ACL settings and 802.1x settings to be
applied.
For example, assume that the MAC Access Control List contains MAC addresses to block, and that WPA-PSK is
configured to allow access to clients with the appropriate PSK Passphrase.
• If the MAC ACL status is set to Enable, WPA-PSK will take precedence, and clients in the MAC ACL with the correct
PSK passphrase will be allowed. Only the WPA-PSK setting is taken into consideration.
• If the MAC ACL status is set to Strict, then clients in the MAC ACL will be blocked even if they have the correct PSK
passphrase. Clients will only be allowed if they have the correct passphrase and are NOT listed in the MAC ACL. In
this way, both MAC and WPA-PSK settings are taken into consideration.
VLANs and Security Profiles
The AP allows you to segment wireless networks into multiple sub-networks based on Network Name (SSID) and VLAN
membership. 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 to segment wireless
networks based on VLAN membership.
Each VLAN can associated to a Security Profile and RADIUS Server Profiles. A Security Profile defines the allowed
wireless clients, and authentication and encryption types. See the following sections for configuration details.
Configuring Security Profiles
Security policies can be configured and applied on the AP as a whole, or on a per VLAN basis. When VLAN is disabled
on the AP, the user can configure a security profile for each interface of the AP. When VLANs are enabled and Security
per SSID is enabled, the user can configure a security profile for each VLAN.
The user defines a security policy by specifying one or more values for the following parameters:
• Wireless STA types (WPA station, 802.11i (WPA2) station, 802.1x station, WEP station, WPA-PSK, and 802.11i-PSK)
that can associate to the AP.
• Authentication mechanisms (802.1x, RADIUS MAC authentication) that are used to authenticate clients for each type
of station.
• Cipher Suites (CCMP, TKIP, WEP, None) used for encapsulating the wireless data for each type of station.
Up to 16 security profiles can be configured.
1. Click Configure > SSID/VLAN/Security > Security Profile.

2. Click Add in the Security Profile Table to create a new entry. To modify an existing profile, select the profile and click
Edit. To delete an existing profile, select the profile and click Delete. You cannot delete a Security Profile used in an
SSID. Also, the first Security Profile cannot be deleted.
3. Configure one or more types of wireless stations (security modes) that are allowed access to the AP under the
security profile. The WEP/PSK parameters are separately configurable for each security mode. To enable a security
mode in the profile (Non Secure Station, WEP Station, 802.1x Station, WPA Station, WPA-PSK Station, 802.11i
(WPA2) Station, 802.11i-PSK Station), check the box next to the mode. See Figure 4-49.
If the security mode selected in a profile is WEP, WPA-PSK, or 802.11i-PSK, then you must configure the WEP or
Pre-Shared Keys.
NOTE: If an 802.1x client that has already been authenticated attempts to switch to WEP, or if a WEP client that has
already been connected attempts to switch to 802.1x, the AP will not allow the client to switch immediately. If
this happens, either reboot the AP or disable the client/roam to a new AP for five minutes, and then attempt to
reconnect to the AP. If the client is still unable to connect after waiting five minutes, reboot the AP.
4. Configure the parameters as follows for each enabled security mode. See Figure 4-49.
•Non Secure Station:
• Authentication Mode: None. The AP allows access to Stations without authentication.
— Non secure station should be used only with WEP or 802.1x security mode.
• Cipher: None
•WEP Station:
• Authentication Mode: None
• Cipher: WEP
• Encryption Key 0, Encryption Key 1, Encryption Key 2, Encryption Key 3
NOTE: When VLAN tagging is enabled, only Key 0 can be configured.
• Encryption Key Length: 64, 128, or 152 Bits.
