Getting Started
Section 2: Getting Started
The D‐Link DWL‐x600AP unified access point (UAP) provides continuous, high‐speed access between wireless
devices and Ethernet devices. It is an advanced, standards‐based solution for wireless networking in businesses
of any size. The UAP enables wireless local area network (WLAN) deployment while providing state‐of‐the‐art
wireless networking features.
The UAP can operate in two modes: Standalone Mode or Managed Mode. In Standalone Mode, the UAP acts
as an individual access point in the network, and you manage it by using the Administrator Web User Interface
(UI), command‐line interface (CLI), or SNMP. In Managed Mode, the UAP is part of the D‐Link Unified Wired and
Wireless System, and you manage it by using the D‐Link Unified Wireless Switch. If an AP is in Managed Mode,
the Administrator Web UI, Telnet, SSH, and SNMP services are disabled.
This document describes how to perform the setup, management, and maintenance of the UAP in Standalone
Mode. For information about configuring the AP in Managed Mode by using the D‐Link Unified Wireless Switch,
see the User Manual for the switch.
Before you power on a new UAP, review the following sections to check required hardware and software
components, client configurations, and compatibility issues. Make sure you have everything you need for a
successful launch and test of your new or extended wireless network.
The DWL‐6600AP and DWL‐8600AP are dual‐radio access points and support the IEEE 802.11a, 802.11b,
802.11g, and 802.11n modes. The DWL‐3600AP is a single‐radio access point and supports the IEEE 802.11b,
IEEE 802.11g, and 802.11n (2.4 GHz) modes.
This section contains the following topics:
• “Administrator’s Computer Requirements”
• “Wireless Client Requirements”
• “Dynamic and Static IP Addressing on the AP”
• “Installing the UAP”
• “Basic Settings”
• “Using the CLI to View the IP Address”
• “Configuring the Ethernet Settings”
• “Configuring IEEE 802.1X Authentication”
• “Verifying the Installation”
• “Configuring Security on the Wireless Access Point”
To manage the UAP by using the Web interface or by using the CLI through Telnet or SSH, the AP needs an IP
address. If you use VLANs or IEEE 802.1X Authentication (port security) on your network, you might need to
configure additional settings on the AP before it can connect to the network.
Note: The WLAN AP is not designed to function as a gateway to the Internet. To connect your WLAN
to other LANs or the Internet, you need a gateway device.

Administrator’s Computer Requirements
Administrator’s Computer Requirements
The following table describes the minimum requirements for the administrator’s computer for configuration
and administration of the UAP through a Web‐based user interface (UI).
Table 2: Requirements for the Administrator’s Computer
Required Software or Component
Description
Serial or Ethernet Connection to the
Access Point
Wireless Connection to the Network
The computer used to configure the first access point must be
connected to the access point by a serial cable or an Ethernet cable.
After initial configuration and launch of the first access point on your
new wireless network, you can make subsequent configuration
changes through the Administration Web pages using a wireless
connection to the internal network. For wireless connection to the
access point, your administration device will need Wi‐Fi capability
similar to that of any wireless client:
Portable or built‐in Wi‐Fi client adapter that supports one or more of
the IEEE 802.11 modes in which you plan to run the access point.
Wireless client software configured to associate with the UAP.
Configuration and administration of the UAP is provided through a
Web‐based user interface hosted on the access point. We
recommend using one of the following supported Web browsers to
access the access point Administration Web pages:
• Microsoft® Internet Explorer® version 7.x or 8.x (with up‐to‐date
patch level for either major version)
• Mozilla® Firefox version 3.5 or later
• Safari 5 and later versions
The administration Web browser must have JavaScript™ enabled to
support the interactive features of the administration interface.
Ensure that security is disabled on the wireless client used to initially
configure the access point.

Wireless Client Requirements
The UAP provides wireless access to any client with a properly configured Wi‐Fi client adapter for the 802.11
mode in which the access point is running. The UAP supports multiple client operating systems. Clients can be
laptop or desktop computers, personal digital assistants (PDAs), or any other hand‐held, portable or stationary
device equipped with a Wi‐Fi adapter and supporting drivers.
To connect to the access point, wireless clients need the software and hardware described in the following
table.
Table 3: Requirements for Wireless Clients
Required Component
Description
Wi‐Fi Client Adapter
Portable or built‐in Wi‐Fi client adapter that supports one or more of the IEEE
802.11 modes in which you plan to run the access point.
Wireless Client Software Client software, such as Microsoft Windows Supplicant, configured to associate
with the UAP.
Client Security Settings
Security should be disabled on the client used to do initial configuration of the
access point.
If the Security mode on the access point is set to anything other than plain text,
wireless clients will need to set a profile to the authentication mode used by the
access point and provide a valid username and password, certificate, or similar user
identity proof. Security modes are Static WEP, IEEE 802.1X, WPA with RADIUS
server, and WPA‐PSK.
For information about configuring security on the access point, see “Virtual Access
Point Settings” on page 70.
Dynamic and Static IP Addressing on the AP
When you power on the access point, the built‐in DHCP client searches for a DHCP server on the network in
order to obtain an IP Address and other network information. If the AP does not find a DHCP server on the
network, the AP continues to use its default Static IP Address (10.90.90.91) until you re‐assign it a new static
IP address (and specify a static IP addressing policy) or until the AP successfully receives network information
from a DHCP server.
To change the connection type and assign a static IP address by using the CLI, see “Configuring the Ethernet
Settings” on page 25 or, by using the Web UI, see “Ethernet Settings” on page 51.
Caution! If you do not have a DHCP server on your internal network, and do not plan to use one, the
first thing you must do after powering on the access point is change the connection type from DHCP
to static IP. You can either assign a new static IP address to the AP or continue using the default
address. We recommend assigning a new static IP address so that if you bring up another WLAN AP
on the same network, the IP address for each AP will be unique.

Dynamic and Static IP Addressing on the AP
Recovering an IP Address
If you experience trouble communicating with the access point, you can recover a static IP address by resetting
the AP configuration to the factory defaults (see “Resetting the Factory Default Configuration” on page 120),
or you can get a dynamically assigned address by connecting the AP to a network that has a DHCP server.
Discovering a Dynamically Assigned IP Address
If you have access to the DHCP server on your network and know the MAC address of your AP, you can view
the new IP address associated with the MAC address of the AP.
If you do not have access to the DHCP server that assigned the IP address to the AP or do not know the MAC
address of the AP, you might need to use the CLI to find out what the new IP address is. For information about
how to discover a dynamically assigned IP address, see “Using the CLI to View the IP Address” on page 24.

Installing the UAP
Installing the UAP
To access the Administration Web UI, you enter the IP address of the AP into a Web browser. You can use the
default IP address of the AP (10.90.90.91) to log on to the AP and assign a static IP address, or you can use a
DHCP server on you network to assign network information to the AP. The DHCP client on the AP is enabled by
default.
To install the UAP, use the following steps:
1. Connect the AP to an administrative PC by using a LAN connection or a direct‐cable connection.
• To use a LAN connection, connect one end of an Ethernet cable to the network port on the access point
and the other end to the same hub where your PC is connected, as shown in the following figure.
The hub or switch you use must permit broadcast signals from the access point to reach all other devices
on the network.
• To use a direct‐cable connection, connect one end of an Ethernet straight‐through or crossover cable to
the network port on the access point and the other end of the cable to the Ethernet port on the PC, as
shown in the following figure. You can also use a serial cable to connect the serial port on the AP to a
serial port on the administrative computer.
For initial configuration with a direct Ethernet connection and no DHCP server, be sure to set your PC to a
static IP address in the same subnet as the default IP address on the access point. (The default IP address
for the access point is 10.90.90.91.)
If you use this method, you will need to reconfigure the cabling for subsequent startup and deployment of
the access point so that the access point is no longer connected directly to the PC but instead is connected
to the LAN (either by using a hub or directly).

Installing the UAP
Note: It is possible to detect access points on the network with a wireless connection. However,
we strongly advise against using this method. In most environments you may have no way of
knowing whether you are actually connecting to the intended AP. Also, many of the initial
configuration changes required will cause you to lose connectivity with the AP over a wireless
connection.
2. Connect the power adapter to the power port on the back of the access point, and then plug the other end
of the power cord into a power outlet.
3. Use your Web browser to log on to the UAP Administration Web pages.
– If the AP did not acquire an IP address from a DHCP server on your network, enter 10.90.90.91 in the
address field of your browser, which is the default IP address of the AP.
– If you used a DHCP server on your network to automatically configure network information for the AP,
enter the new IP address of the AP into the Web browser.
– If you used a DHCP server and you do not know the new IP address of the AP, use the following
procedures to obtain the information:
a. Connect a serial cable from the administrative computer to the AP and use a terminal emulation
program to access the command‐line interface (CLI).
b. At the login prompt, enter admin for the user name and admin for the password. At the command
prompt, enter get management.
– The command output displays the IP address of the AP. Enter this address in the address field of your
browser. For a more detailed explanation about how to log on to the CLI by using the console port, see
“Using the CLI to View the IP Address” on page 24.

Note: The changes you make are not saved or applied until you click Apply. Changing some access
point settings might cause the AP to stop and restart system processes. If this happens, wireless
clients will temporarily lose connectivity. We recommend that you change access point settings
when WLAN traffic is low.
For information about the fields and configuration options on the Basic Settings page, see “Basic Settings”
on page 22.
6. If you do not have a DHCP server on the management network and do not plan to use one, you must change
the Connection Type from DHCP to Static IP.
You can either assign a new Static IP address to the AP or continue using the default address. We
recommend assigning a new Static IP address so that if you bring up another UAP on the same network,
the IP address for each AP will be unique. To change the connection type and assign a static IP address, see
“Configuring the Ethernet Settings” on page 25 (CLI) or “Ethernet Settings” on page 51 (Web).
7. If your network uses VLANs, you might need to configure the management VLAN ID or untagged VLAN ID
on the UAP in order for it to work with your network.
For information about how to configure VLAN information, see “Configuring the Ethernet Settings” on
page 25 (CLI) or “Ethernet Settings” on page 51 (Web).
8. If your network uses IEEE 802.1X port security for network access control, you must configure the 802.1X
supplicant information on the AP.
For information about how to configure the 802.1X user name and password, see “Configuring IEEE 802.1X
Authentication” on page 27.

Using the CLI to View the IP Address
Connecting to the AP Web Interface by Using the IPv6 Address
To connect to the AP by using the IPv6 global address or IPv6 link local address, you must enter the AP address
into your browser in a special format.
Note: The following instructions and examples work with Microsoft Internet Explorer 7 (IE7) and
might not work with other browsers.
To connect to an IPv6 global address, add square brackets around the IPv6 address. For example, if the AP
global IPv6 address is 2520::230:abff:fe00:2420, type the following address into the IE7 address field: http://
[2520::230:abff:fe00:2420].
To connect to the iPv6 link local address, replace the colons (:) with hyphens (‐), add the interface number
preceded with an "s," then add ".ipv6‐literal.net." For example, if the AP link local address is
fe80::230:abff:fe00:2420, and the Windows interface is defined as "%6," type the following address into the
IE7 address field: http://fe80‐‐230‐abff‐fe00‐2420s6.ipv6‐literal.net.
Using the CLI to View the IP Address
The DHCP client on the UAP is enabled by default. If you connect the UAP to a network with a DHCP server, the
AP automatically acquires an IP address. To manage the UAP by using the Administrator UI, you must enter the
IP address of the access point into a Web browser.
If a DHCP server on your network assigns an IP address to the UAP, and you do not know the IP address, use
the following steps to view the IP address of the UAP:
1. Using a null‐modem cable, connect a VT100/ANSI terminal or a workstation to the console (serial) port.
If you attached a PC, Apple, or UNIX workstation, start a terminal‐emulation program, such as
HyperTerminal or TeraTerm.
2. Configure the terminal‐emulation program to use the following settings:
• Baud rate: 115200 bps
• Data bits: 8
• Parity: none
• Stop bit: 1
• Flow control: none
3. Press the return key, and a login prompt should appear.
The login name is admin. The default password is admin. After a successful login, the screen shows the

Information similar to the following prints to the screen.
Configuring the Ethernet Settings
The default Ethernet settings, which include DHCP and VLAN information, might not work for all networks.
By default, the DHCP client on the UAP automatically broadcasts requests for network information. If you want
to use a static IP address, you must disable the DHCP client and manually configure the IP address and other
network information.
The management VLAN is VLAN 1 by default. This VLAN is also the default untagged VLAN. If you already have
a management VLAN configured on your network with a different VLAN ID, you must change the VLAN ID of
the management VLAN on the access point.
For information about using the Web interface to configure the Ethernet settings, see “Ethernet Settings” on

Verifying the Installation
Make sure the access point is connected to the LAN and associate some wireless clients with the network. Once
you have tested the basics of your wireless network, you can enable more security and fine‐tune the AP by
modifying advanced configuration features.
1. Connect the access point to the LAN.
• If you configured the access point and administrator PC by connecting both into a network hub, then
your access point is already connected to the LAN. The next step is to test some wireless clients.
• If you configured the access point by using a direct cable connection from your computer to the access
point, do the following procedures:
a. Disconnect the cable from the computer and the access point.
b. Connect an Ethernet cable from the access point to the LAN.
c. Connect your computer to the LAN by using an Ethernet cable or a wireless card.
2. Test LAN connectivity with wireless clients.
Test the UAP by trying to detect it and associate with it from some wireless client devices. For information
about requirements for these clients, see “Wireless Client Requirements” on page 17.
3. Secure and configure the access point by using advanced features.
Once the wireless network is up and you can connect to the AP with some wireless clients, you can add in
layers of security, create multiple virtual access points (VAPs), and configure performance settings.
Note: The WLAN AP is not designed for multiple, simultaneous configuration changes. If more than
one administrator is logged onto the Administration Web pages and making changes to the
configuration, there is no guarantee that all configuration changes specified by multiple users will
be applied.
By default, no security is in place on the access point, so any wireless client can associate with it and access
your LAN. An important next step is to configure security, as described in “Virtual Access Point Settings” on
page 70.

Configuring Security on the Wireless Access Point
Configuring Security on the Wireless Access Point
You configure secure wireless client access by configuring security for each virtual access point (VAP) that you
enable. You can configure up to 16 VAPs per radio that simulate multiple APs in one physical access point. By
default, only one VAP is enabled. For each VAP, you can configure a unique security mode to control wireless
client access.
Each radio has 16 VAPs, with VAP IDs from 0‐15. By default, only VAP 0 on each radio is enabled. VAP0 has the
following default settings:
• VLAN ID: 1
• Broadcast SSID: Enabled
• SSID: dlink1
• Security: None
• MAC Authentication Type: None
• Redirect Mode: None
All other VAPs are disabled by default. The default SSID for VAPs 1 – 15 is "dlinkx" where x is the VAP ID.
To prevent unauthorized access to the UAP, we recommend that you select and configure a security option
other than None for the default VAP and for each VAP that you enable.
For information about how to configure the security settings on each VAP, see “Virtual Access Point Settings”
on page 70.

• Set a Severity Level to determine what category of log messages are displayed.
• Set Depth to determine how many log messages are displayed in the Event log.
• Enable a remote log relay host to capture all system events and errors in a Kernel Log.
Note: The AP acquires its date and time information using the network time protocol (NTP). This data
is reported in UTC format (also known as Greenwich Mean Time). You need to convert the reported
time to your local time. For information on setting the network time protocol, see “” on page 106.

Viewing Events
Configuring the Log Relay Host for Kernel Messages
The Kernel Log is a comprehensive list of system events (shown in the System Log) and kernel messages such
as error conditions, like dropping frames.
You cannot view kernel log messages directly from the Administration Web UI for an AP. You must first set up
a remote server running a syslog process and acting as a syslog log relay host on your network. Then, you can
configure the UAP to send syslog messages to the remote server.
Remote log server collection for AP syslog messages provides the following features:
• Allows aggregation of syslog messages from multiple APs
• Stores a longer history of messages than kept on a single AP
• Triggers scripted management operations and alerts
To use Kernel Log relaying, you must configure a remote server to receive the syslog messages. The procedure
to configure a remote log host depends on the type of system you use as the remote host.
Note: The syslog process will default to use port 514. We recommend keeping this default port.
However; If you choose to reconfigure the log port, make sure that the port number you assign to
syslog is not being used by another process.

each station.
Table 10 describes the fields on the Client Associations page.
Table 10: Associated Clients
Field
Description
Network
Shows which VAP the client is associated with. For example, an entry of wlan0vap2 means the
client is associated with Radio 1, VAP 2.
An entry of wlan0 means the client is associated with VAP 0 on Radio 1. An entry of wlan1
means the client is associated with VAP 0 on Radio 2.
Station
Shows the MAC address of the associated wireless client.
Status
The Authenticated and Associated Status shows the underlying IEEE 802.11 authentication
and association status, which is present no matter which type of security the client uses to
connect to the AP. This status does not show IEEE 802.1X authentication or association status.
Some points to keep in mind with regard to this field are:
• If the AP security mode is None or Static WEP, the authentication and association status of
clients showing on the Client Associations page will be in line with what is expected; that
is, if a client shows as authenticated to the AP, it will be able to transmit and receive data.
(This is because Static WEP uses only IEEE 802.11 authentication.)
• If the AP uses IEEE 802.1X or WPA security, however, it is possible for a client association to
show on this page as authenticated (via the IEEE 802.11 security) but actually not be
authenticated to the AP via the second layer of security.
From Station Shows the number of packets and bytes received from the wireless client and the number of
packets and bytes that were dropped after being received.

Viewing TSPEC Client Associations
The TSPEC Client Association Status and Statistics page provides some basic information about the client
associations status and a real‐time display of the transmit and receive statistics for the TSPEC clients. All
transmit and receive statistics shown are totals since the client association started.
A TSPEC is a traffic specification that is sent from a QoS‐capable wireless client to an AP requesting a certain
amount of network access for the traffic stream (TS) it represents. A traffic stream is a collection of data packets
identified by the wireless client as belonging to a particular user priority. An example of a voice traffic stream
is a Wi‐Fi CERTIFIED™ telephone handset that marks its codec‐generated data packets as voice priority traffic.
An example of a video traffic stream is a video player application on a wireless laptop that prioritizes a video
conference feed from a corporate server.
To view TSPEC client association statistics, click the TSPEC Client Associations tab.

Viewing Rogue AP Detection
Link Integrity Monitoring
The UAP provides link integrity monitoring to continually verify its connection to each associated client. To do
this, the AP sends data packets to clients every few seconds when no other traffic is passing. This allows the AP
to detect when a client goes out of range, even during periods when no normal traffic is exchanged. The client
connection drops off the list within 300 seconds if these data packets are not acknowledged, even if no
disassociation message is received.
Viewing Rogue AP Detection
The status page to view Rogue AP Detection information provides real‐time statistics for all APs within range
of the AP on which you are viewing the Administration Web pages. When AP detection is enabled, the radio
will periodically switch from its operating channel to scan other channels within the same band. Click Refresh
to update the screen and display the most current information.
The Rogue AP Detection page contains the following two lists:
• Detected Rogue AP List — Lists all APs within range of the AP that have not been acknowledged as known
APs.
• Known AP List — Lists all APs within range of the AP that have been acknowledged as known APs either by
clicking the Grant button associated with an AP in the Detected Rogue AP List or by appearing in an

Ethernet Settings
The default wired interface settings, which include DHCP and VLAN information, might not work for all
networks.
By default, the DHCP client on the UAP automatically broadcasts requests for network information. If you want
to use a static IP address, you must disable the DHCP client and manually configure the IP address and other
network information.
The management VLAN is VLAN 1 by default. This VLAN is also the default untagged VLAN. If you already have
a management VLAN configured on your network with a different VLAN ID, you must change the VLAN ID of
the management VLAN on the AP.

SNMP traps) associated clients that do not adhere to mandatory admission control
procedures.
Specify whether you want the radio interface on or off.
Indicates the Media Access Control (MAC) addresses for the interface. Dual‐radio APs have
a unique MAC address for each radio.
A MAC address is a permanent, unique hardware address for any device that represents
an interface to the network. The MAC address is assigned by the manufacturer. You cannot
change the MAC address. It is provided here for informational purposes as a unique
identifier for an interface.
The Mode defines the Physical Layer (PHY) standard the radio uses.
Note: The modes available depend on the country code setting and the radio selected.
Select one of the following modes for radio 1 (DWL‐6600AP and DWL‐8600AP only):
• IEEE 802.11a is a PHY standard that specifies operating in the 5 GHz U‐NII band using
orthogonal frequency division multiplexing (OFDM). It supports data rates ranging
from 6 to 54 Mbps.
• IEEE 802.11a/n operates in the 5 GHz ISM band and includes support for both 802.11a
and 802.11n devices. IEEE 802.11n is an extension of the 802.11 standard that includes
multiple‐input multiple‐output (MIMO) technology. IEEE 802.11n supports data ranges
of up to 248 Mbps and nearly twice the indoor range of 802.11 b, 802.11g, and
802.11a.
• 5 GHz IEEE 802.11n is the recommended mode for networks with 802.11n devices that
operate in the 5 GHz frequency that do not need to support 802.11a devices. IEEE
802.11n can achieve a higher throughput when it does not need to be compatible with
legacy devices (802.11a).
Select one of the following modes for radio 2:
• IEEE 802.11b/g operates in the 2.4 GHz ISM band. IEEE 802.11b is an enhancement of
the initial 802.11 PHY to include 5.5 Mbps and 11 Mbps data rates. It uses direct
sequence spread spectrum (DSSS) or frequency hopping spread spectrum (FHSS) as
well as complementary code keying (CCK) to provide the higher data rates. It supports
data rates ranging from 1 to 11 Mbps. IEEE 802.11g is a higher speed extension (up to
54 Mbps) to the 802.11b PHY. It uses orthogonal frequency division multiplexing
(OFDM). It supports data rates ranging from 1 to 54 Mbps.
• IEEE 802.11b/g/n operates in the 2.4 GHz ISM band and includes support for 802.11b,
802.11g, and 802.11n devices.
• 2.4 GHz IEEE 802.11n is the recommended mode for networks with 802.11n devices
that operate in the 2.4 GHz frequency that do not need to support 802.11b/g devices.
IEEE 802.11n can achieve a higher throughput when it does not need to be compatible
with legacy devices (802.11b/g).

Description
Channel
Select the Channel.
The range of available channels is determined by the mode of the radio interface and the
country code setting. If you select Auto for the channel setting, the AP scans available
channels and selects a channel where no traffic is detected.
The Channel defines the portion of the radio spectrum the radio uses for transmitting and
receiving. Each mode offers a number of channels, depending on how the spectrum is
licensed by national and transnational authorities such as the Federal Communications
Commission (FCC) or the International Telecommunication Union (ITU‐R).
When automatic channel assignment is enabled on the Channel Management page for
Clustering, the channel policy for the radio is automatically set to static mode, and the
Auto option is not available for the Channel field. This allows the automatic channel
feature to set the channels for the radios in the cluster.
To enable Station Isolation, select the check box directly beside it.
When Station Isolation is disabled, wireless clients can communicate with one another
normally by sending traffic through the AP.
When Station Isolation is enabled, the AP blocks communication between wireless clients
on the same radio and VAP. The AP still allows data traffic between its wireless clients and
wired devices on the network, across a WDS link, and with other wireless clients
associated with a different VAP, but not among wireless clients associated with the same
VAP.
Note: On dual‐radio APs, Station Isolation does not block communication between Radio 1
and Radio 2, even if the VAP configuration on each radio is the same.
AeroScout Engine support provides location‐based services for wireless networks. Specify
whether to enable support for the AeroScout protocol.
Options are Enabled or Disabled. The default is Disabled. When enabled, Aeroscout
devices are recognized and data is sent to an Aeroscout Engine (AE) for analysis. The AE
determines the geographical location of 802.11‐capable devices, such as STAs, APs, and
AeroScout’s line of 802.11‐enabled RFID devices, or tags. The AE communicates with APs
that support the AE protocol in order to collect information about the RF devices detected
by the APs. Using the AE protocol, D‐Link supports direct communication between AE and
the APs. When operating in managed mode, the AE is configured with the IP address of the
managed access points from which it collects information. The Wireless Switch cannot
communicate with the AE.
For more information about the AeroScout protocol, see “Enabling AeroScout™ Engine
Support” on page 57.
Note: Only AeroScout tag hardware of types T2 and T3 are explicitly supported. Other tag
models are also supported only if their implementation of the AeroScout protocol
conforms to the AeroScout Engine ‐ Access Point Interface Specification, version 2.1.
Note: AeroScout tags operate only in 802.11 b/g mode. Therefore, network administrators
who use the AeroScout tags must configure at least one radio on APs that are expected to
detect tags in either 802.11b/g or 802.11b/g/n mode. The radios configured in 2.4 GHz
IEEE 802.11 mode or any of the 5GHZ modes cannot detect AeroScout tags.
Note: The AE protocol allows access points to mark detected APs as rogue devices. The D‐
Link APs do not support this feature and never report detected APs as rogues.

happens, wireless clients will temporarily lose connectivity. We recommend that you change AP
settings when WLAN traffic is low.
Using the 802.11h Wireless Mode
For 802.11a radios, if the regulatory domain requires radar detection on the channel, the Dynamic Frequency
Selection (DFS) and Transmit Power Control (TPC) features of 802.11h are automatically activated.
There are a number of key points about the IEEE 802.11h standard:
• 802.11h only works for the 802.11a band. It is not required for 802.11b or 802.11g.
• If you are operating in an 802.11h enabled domain, the AP attempts to use the channel you assign. If the
channel has been blocked by a previous radar detection, or if the AP detects a radar on the channel, then
the AP automatically selects a different channel.
• When 802.11h is enabled, the AP will not be operational in the 5GHz band for at least 60 seconds due to
radar scanning.
• Setting up WDS links may be difficult when 802.11h is operational. This is because the operating channels
of the two APs on the WDS link may keep changing depending on channel usage and radar interference.
WDS will only work if both the APs operate on the same channel. For more information on WDS, see
“Configuring Load Balancing” on page 88.
Enabling AeroScout™ Engine Support
The AeroScout Engine (AE) is a software platform produced by AeroScout Inc. for location‐based services. The
AE can determine the physical location of 802.11‐capable AeroScout devices. The AE communicates with APs
that have the AE protocol enabled in order to collect information about the RF devices detected by the APs.
The DWS‐4000 Series switch supports only direct communication between the AE and the APs. When
operating in managed mode, the AE is configured with the IP address of the managed access points from which
it collects information. The DWS‐4000 Series switch does not communicate with the AE.
AeroScout tags operate only in 802.11b/g mode. Therefore, network administrators who use the AeroScout
tags must configure at least one radio on APs that are expected to detect tags in either 802.11b/g or
802.11b/g/n mode. The radios configured in 2.4 GHz IEEE 802.11n mode or any of the 5 GHz modes cannot
detect AeroScout tags.

Note: The following notes apply to AeroScout product and protocol support:
• D‐Link does not sell AeroScout products. Contact AeroScout for AeroScout hardware, software or
deployment information.
• The AE protocol does not support any authentication or encryption between the AE server and
the access point.
• The AE protocol requires radios to operate in promiscuous mode. This means that the AP receives
and processes all packets detected by the radios, as opposed to processing only packets destined
to the APs BSSID. This can affect AP throughput.

Channel
Select the Channel.
The range of available channels is determined by the mode of the radio interface and the

The channel defines the portion of the radio spectrum the radio uses for transmitting and

When automatic channel assignment is enabled on the Channel Management page for
Clustering, the channel policy for the radio is automatically set to static mode, and the
Auto option is not available for the Channel field. This allows the automatic channel
feature to set the channels for the radios in the cluster.
Channel Bandwidth The 802.11n specification allows a 40‐MHz‐wide channel in addition to the legacy 20‐
MHz channel available with other modes. The 40‐MHz channel enables higher data rates
(802.11n modes
but leaves fewer channels available for use by other 2.4 GHz and 5 GHz devices.

Primary Channel
This setting can be changed only when the channel bandwidth is set to 40 MHz. A 40‐

MHz channel can be considered to consist of two 20‐MHz channels that are contiguous
only)
in the frequency domain. These two 20‐MHz channels are often referred to as the
Primary and Secondary channels. The Primary Channel is used for 802.11n clients that
support only a 20‐MHz channel bandwidth and for legacy clients.
Select one of the following options:
• Upper — Set the Primary Channel as the upper 20‐MHz channel in the 40‐MHz band.
• Lower — Set the Primary Channel as the lower 20‐MHz channel in the 40‐MHz band.
Short Guard
This field is available only if the selected radio mode includes 802.11n.
Interval Supported The guard interval is the dead time, in nanoseconds, between OFDM symbols. The guard
interval prevents Inter‐Symbol and Inter‐Carrier Interference (ISI, ICI). The 802.11n mode
allows for a reduction in this guard interval from the a and g definition of 800
nanoseconds to 400 nanoseconds. Reducing the guard interval can yield a 10%
improvement in data throughput.
Select one of the following options:
• Yes — The AP transmits data using a 400 ns guard Interval when communicating with
clients that also support the short guard interval.
• No — The AP transmits data using an 800 ns guard interval.
STBC Mode
This field is available only if the selected radio mode includes 802.11n.
Space Time Block Coding (STBC) is an 802.11n technique intended to improve the
reliability of data transmissions. The data stream is transmitted on multiple antennas so
the receiving system has a better chance of detecting at least one of the data streams.
Select one of the following options:
• On — The AP transmits the same data stream on multiple antennas at the same time.
• Off — The AP does not transmits the same data on multiple antennas.

Description
Protection
The protection feature contains rules to guarantee that 802.11n transmissions do not
cause interference with legacy stations or APs. By default, these protection mechanisms
are enabled (Auto). With protection enabled, protection mechanisms will be invoked if
legacy devices are within range of the AP. This causes more overhead on every
transmission, which will impact performance. However, there is no impact on
performance if there are no legacy devices within range of the AP.
You can disable (Off) these protection mechanisms; however, when 802.11n protection
is off, legacy clients or APs within range can be affected by 802.11n transmissions. The
802.11 protection feature is also available when the mode is 802.11b/g. When
protection is enabled in this mode, it protects 802.11b clients and APs from 802.11g
transmissions.
Note: This setting does not affect the ability of the client to associate with the AP.
Beacon frames are transmitted by an AP at regular intervals to announce the existence
of the wireless network. The default behavior is to send a beacon frame once every 100
milliseconds (or 10 per second).
Enter a value from 20 to 2000 milliseconds.
Specify a DTIM period from 1 to 255 beacons.
The Delivery Traffic Information Map (DTIM) message is an element included in some
Beacon frames. It indicates which client stations, currently sleeping in low‐power mode,
have data buffered on the AP awaiting pick‐up.
The DTIM period you specify indicates how often the clients served by this AP should
check for buffered data still on the AP awaiting pickup.
The measurement is in beacons. For example, if you set this field to 1, clients will check
for buffered data on the AP at every beacon. If you set this field to 10, clients will check
on every 10th beacon.
Specify a number between 256 and 2,346 to set the frame size threshold in bytes.
The fragmentation threshold is a way of limiting the size of packets (frames) transmitted
over the network. If a packet exceeds the fragmentation threshold you set, the
fragmentation function is activated and the packet is sent as multiple 802.11 frames.
If the packet being transmitted is equal to or less than the threshold, fragmentation is not
used.
Setting the threshold to the largest value (2,346 bytes) effectively disables
fragmentation. Fragmentation plays no role when Aggregation is enabled.
Fragmentation involves more overhead both because of the extra work of dividing up
and reassembling of frames it requires, and because it increases message traffic on the
network. However, fragmentation can help improve network performance and reliability
if properly configured.
Sending smaller frames (by using lower fragmentation threshold) might help with some
interference problems; for example, with microwave ovens.
By default, fragmentation is off. We recommend not using fragmentation unless you
suspect radio interference. The additional headers applied to each fragment increase the
overhead on the network and can greatly reduce throughput.

RTS Threshold
Specify a Request to Send (RTS) Threshold value between 0 and 2347.
The RTS threshold indicates the number of octets in an MPDU, below which an RTS/CTS
handshake is not performed.
Changing the RTS threshold can help control traffic flow through the AP, especially one
with a lot of clients. If you specify a low threshold value, RTS packets will be sent more
frequently. This will consume more bandwidth and reduce the throughput of the packet.
On the other hand, sending more RTS packets can help the network recover from
interference or collisions which might occur on a busy network, or on a network
experiencing electromagnetic interference.
Maximum Stations Specify the maximum number of stations allowed to access this AP at any one time.
You can enter a value between 0 and 200.
Transmit Power
Enter a percentage value for the transmit power level for this AP.
The default value, which is 100%, can be more cost‐efficient than a lower percentage
since it gives the AP a maximum broadcast range and reduces the number of APs needed.
To increase capacity of the network, place APs closer together and reduce the value of
the transmit power. This helps reduce overlap and interference among APs. A lower
transmit power setting can also keep your network more secure because weaker wireless
signals are less likely to propagate outside of the physical location of your network.

• Rates are expressed in megabits per second.
• Supported Rate Sets indicate rates that the AP supports. You can check multiple rates
(click a check box to select or de‐select a rate). The AP will automatically choose the
most efficient rate based on factors like error rates and distance of client stations
from the AP.
• Basic Rate Sets indicate rates that the AP will advertise to the network for the
purposes of setting up communication with other APs and client stations on the
network. It is generally more efficient to have an AP broadcast a subset of its
supported rate sets.

Configuring Radio and VAP Scheduler
Configuring Radio and VAP Scheduler
The Radio and VAP scheduler is a standalone DWL‐x600AP feature. To configure the Radio and VAP scheduler,
select the Scheduler tab in the Manage section. The Radio and VAP Scheduler allows you to configure a rule
with a specific time interval for VAPs or radios to be operational, thereby automating the enabling or disabling
of the VAPs and Radios.
One of the ways you can use this feature is to schedule radios to operate only during the office working hours
in order to achieve security and reduce power consumption. You can also use the Scheduler to allow access to
VAPs for wireless clients only during specific times of day.
Each rule specifies the start time, end time and day (or days) of the week the radio or VAP can be operational.
The rules are periodic in nature and are repeated every week.
A valid rule must contain all of the following parameters:
• Days of the Week
• Start Time (hour and minutes)
• End Time (hour and minutes)
Only valid rules are added to the profile. Up to 16 rules are grouped together to form a scheduling profile. Any
two periodic rules time entries belonging to the same profile must not overlap. The time granularity for the
schedules is one minute. The DWL‐x600AP supports up to 16 profiles.

For a Scheduler profile to take effect, you must associate it with at least one radio or VAP interface. To associate
the Scheduler profiles, select the Scheduler Association tab in the Manage section. By default, there are no
Scheduler profiles created, so no profile is associated to any radio or VAP. The Scheduler profile needs to be
explicitly associated to a radio or VAP configuration. Only one Scheduler profile can be associated to any radio
or VAP configuration; however, a single profile can be associated to multiple radios or VAPs. If the Scheduler
profile associated with a VAP or radio is deleted, then the associated profile to the VAP or radio is removed
implicitly. If the radio is operationally disabled, then all the VAPs associated to that radio are also operationally
disabled irrespective of the VAP configuration.

To change VAP 0 or to enable and configure additional VAPs, select the VAP tab in the Manage section.
VAPs segment the wireless LAN into multiple broadcast domains that are the wireless equivalent of Ethernet
VLANs. VAPs simulate multiple APs in one physical AP. Each radio supports up to 16 VAPs.
For each VAP, you can customize the security mode to control wireless client access. Each VAP can also have a
unique SSID. Multiple SSIDs make a single AP look like two or more APs to other systems on the network. By
configuring VAPs, you can maintain better control over broadcast and multicast traffic, which affects network
performance.
You can configure each VAP to use a different VLAN, or you can configure multiple VAPs to use the same VLAN,
whether the VLAN is on the same radio or on a different radio. VAP0, which is always enabled on both radios,
is assigned to the default VLAN 1.
The AP adds VLAN ID tags to wireless client traffic based on the VLAN ID you configure on the VAP page or by
using the RADIUS server assignment. If you use an external RADIUS server, you can configure multiple VLANs
on each VAP. The external RADIUS server assigns wireless clients to the VLAN when the clients associate and
authenticate.
You can configure up to four global IPv4 or IPv6 RADIUS servers. One of the servers always acts as a primary
while the others act as backup servers. The network type (IPv4 or IPv6) and accounting mode are common
across all configured RADIUS servers. You can configure each VAP to use the global RADIUS server settings,
which is the default, or you can configure a per‐VAP RADIUS server set. You can also configure separate RADIUS
server settings for each VAP. For example, you can configure one VAP to use an IPv6 RADIUS server while other
VAPs use the global IPv4 RADIUS server settings you configure.
If wireless clients use a security mode that does not communicate with the RAIDUS server, or if the RADIUS
server does not provide the VLAN information, you can assign a VLAN ID to each VAP. The AP assigns the VLAN
to all wireless clients that connect to the AP through that VAP.
Note: Before you configure VLANs on the AP, be sure to verify that the switch and DHCP server the AP
uses can support IEEE 802.1Q VLAN encapsulation.
To set up multiple VAPs, click Manage > VAP.

RADIUS IP Address Specify the IP version that the RADIUS server uses.
Type
You can toggle between the address types to configure IPv4 and IPv6 global RADIUS
address settings, but the AP contacts only the RADIUS server or servers for the address
type you select in this field.
RADIUS IP Address Enter the IPv4 or IPv6 address for the primary global RADIUS server. By default, each VAP
uses the global RADIUS settings that you define for the AP at the top of the VAP page.
RADIUS IPv6
Address
When the first wireless client tries to authenticate with the AP, the AP sends an
authentication request to the primary server. If the primary server responds to the
authentication request, the AP continues to use this RADIUS server as the primary server,
and authentication requests are sent to the address you specify.
If the IPv4 RADIUS IP Address Type option is selected in the previous field, enter the IP
address of the RADIUS server that all VAPs use by default, for example 192.168.10.23. If
the IPv6 RADIUS IP Address Type option is selected, enter the IPv6 address of the primary
global RADIUS server, for example 2001:0db8:1234::abcd.
RADIUS IP or IPv6 Enter up to three IPv4 or IPv6 addresses to use as the backup RADIUS servers. The field
label is RADIUS IP Address when the IPv4 RADIUS IP Address Type option is selected and
Address 1 – 3
RADIUS IPv6 Address when the IPv6 RADIUS IP Address Type option is selected.
If authentication fails with the primary server, each configured backup server is tried in
sequence. The IPv4 or IPv6 address must be valid in order for the AP to attempt to
contact the server.

RADIUS Key
Enter the RADIUS key in the text box.
The RADIUS Key is the shared secret key for the global RADIUS server. You can use up to
63 standard alphanumeric and special characters. The key is case sensitive, and you must
configure the same key on the AP and on your RADIUS server. The text you enter will be
displayed as “*” characters to prevent others from seeing the RADIUS key as you type.
Enter the RADIUS key associated with the configured backup RADIUS servers. The server
at RADIUS IP Address‐1 uses RADIUS Key‐1, RADIUS IP Address‐2 uses RADIUS Key‐2, and
so on.
Select this option to track and measure the resources a particular user has consumed
such as system time, amount of data transmitted and received, and so on.
If you enable RADIUS accounting, it is enabled for the primary RADIUS server and all
backup servers.
Select this option to allow the secondary RADIUS server to authenticate wireless clients
if the authentication with the primary RADIUS server is unsuccessful, or if the primary
RADIUS server is unavailable.
Select the radio to configure. VAPs are configured independently on each radio.
Note: The DWL‐3600AP supports only one radio.
You can configure up to 16 VAPs for each radio. VAP0 is the physical radio interface, so to
disable VAP0, you must disable the radio.
You can enable or disable a configured network.
• To enable the specified network, select the Enabled option beside the appropriate
VAP.
• To disable the specified network, clear the Enabled option beside the appropriate
VAP.
If you disable the specified network, you will lose the VLAN ID you entered.
When a wireless client connects to the AP by using this VAP, the AP tags all traffic from
the wireless client with the VLAN ID you enter in this field unless you enter the untagged
VLAN ID or use a RADIUS server to assign a wireless client to a VLAN. The range for the
VLAN ID is 1 – 4094.
If you use RADIUS‐based authentication for clients, you can optionally add the following
attributes to the appropriate file in the RADIUS or AAA server to configure a VLAN for the
client:
• “Tunnel‐Type”
• “Tunnel‐Medium‐Type”
• “Tunnel‐Private‐Group‐ID”
The RADIUS‐assigned VLAN ID overrides the VLAN ID you configure on the VAP page.
You configure the untagged and management VLAN IDs on the Ethernet Settings page.
For more information, see “Ethernet Settings” on page 51.
Enter a name for the wireless network. The SSID is an alphanumeric string of up to 32
characters. You can use the same SSID for multiple VAPs, or you can choose a unique SSID
for each VAP.
Note: If you are connected as a wireless client to the same AP that you are administering,
resetting the SSID will cause you to lose connectivity to the AP. You will need to reconnect
to the new SSID after you save this new setting.

Description
Broadcast SSID
Specify whether to allow the AP to broadcast the Service Set Identifier (SSID) in its
beacon frames. The Broadcast SSID parameter is enabled by default. When the VAP does
not broadcast its SSID, the network name is not displayed in the list of available networks
on a client station. Instead, the client must have the exact network name configured in
the supplicant before it is able to connect.
• To enable the SSID broadcast, select the Broadcast SSID check box.
• To prohibit the SSID broadcast, clear the Broadcast SSID check box.
Note: Disabling the broadcast SSID is sufficient to prevent clients from accidentally
connecting to your network, but it will not prevent even the simplest of attempts by a
hacker to connect or monitor unencrypted traffic. Suppressing the SSID broadcast offers
a very minimal level of protection on an otherwise exposed network (such as a guest
network) where the priority is making it easy for clients to get a connection and where
no sensitive information is available.
Select one of the following Security modes for this VAP:
• None
• Static WEP
• WPA Personal
• IEEE 802.1X
• WPA Enterprise
If you select a security mode other than None, additional fields appear. These fields are
explained below.
Note: The Security mode you set here is specifically for this VAP.
You can configure a global list of MAC addresses that are allowed or denied access to the
network. The drop‐down menu for this feature allows you to select the type of MAC
Authentication to use:
• Disabled: Do not use MAC Authentication.
• Local: Use the MAC Authentication list that you configure on the MAC Authentication
page.
• RADIUS: Use the MAC Authentication list on the external RADIUS server.

Enable the HTTP redirect feature to redirect wireless clients to a custom Web page.
When redirect mode is enabled, the user will be redirected to the URL you specify after
the wireless client associates with an AP and the user opens a Web browser on the client
to access the Internet.
The custom Web page must be located on an external Web server and might contain
information such as the company logo and network usage policy.
Note: The wireless client is redirected to the external Web server only once while it is
associated with the AP.

Note: After you configure the VAP settings, you must click Apply to apply the changes and to save the
settings. Changing some settings might cause the AP to stop and restart system processes. If this
happens, wireless clients will temporarily lose connectivity. We recommend that you change AP
settings when WLAN traffic is low.
None (Plain‐text)
If you select None as your security mode, no further options are configurable on the AP. This mode means that
any data transferred to and from the UAP is not encrypted.This security mode can be useful during initial
network configuration or for problem solving, but it is not recommended for regular use on the Internal
network because it is not secure.
Static WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. All wireless stations
and APs on the network are configured with a static 64‐bit (40‐bit secret key + 24‐bit initialization vector (IV))
or 128‐bit (104‐bit secret key + 24‐bit IV) Shared Key for data encryption.
Static WEP is not the most secure mode available, but it offers more protection than setting the security mode
to None (Plain‐text) as it does prevent an outsider from easily sniffing out unencrypted wireless traffic.
WEP encrypts data moving across the wireless network based on a static key. (The encryption algorithm is a
stream cipher called RC4.)

Table 23: Static WEP (Cont.)
Field
Description
WEP Keys
You can specify up to four WEP keys. In each text box, enter a string of characters for each
key. The keys you enter depend on the key type selected:
• ASCII — Includes upper and lower case alphabetic letters, the numeric digits, and
special symbols such as @ and #.
• Hex — Includes digits 0 to 9 and the letters A to F.
Use the same number of characters for each key as specified in the Characters Required
field. These are the RC4 WEP keys shared with the stations using the AP.
Each client station must be configured to use one of these same WEP keys in the same
slot as specified here on the AP.
Characters Required: The number of characters you enter into the WEP Key fields is
determined by the Key length and Key type you select. For example, if you use 128‐bit
ASCII keys, you must enter 26 characters in the WEP key. The number of characters
required updates automatically based on how you set Key Length and Key Type.
The authentication algorithm defines the method used to determine whether a client
station is allowed to associate with an AP when static WEP is the security mode.
Specify the authentication algorithm you want to use by choosing one of the following
options:
• Open System authentication allows any client station to associate with the AP
whether that client station has the correct WEP key or not. This algorithm is also used
in plaintext, IEEE 802.1X, and WPA modes. When the authentication algorithm is set
to Open System, any client can associate with the AP.
Note: Just because a client station is allowed to associate does not ensure it can
exchange traffic with an AP. A station must have the correct WEP key to be able to
successfully access and decrypt data from an AP, and to transmit readable data to the AP.
• Shared Key authentication requires the client station to have the correct WEP key in
order to associate with the AP. When the authentication algorithm is set to Shared
Key, a station with an incorrect WEP key will not be able to associate with the AP.
• Both Open System and Shared Key. When you select both authentication algorithms:
– Client stations configured to use WEP in shared key mode must have a valid WEP
key in order to associate with the AP.
– Client stations configured to use WEP as an open system (shared key mode not
enabled) will be able to associate with the AP even if they do not have the correct
WEP key.

Static WEP Rules
If you use Static WEP, the following rules apply:
• All client stations must have the Wireless LAN (WLAN) security set to WEP, and all clients must have one of
the WEP keys specified on the AP in order to de‐code AP‐to‐station data transmissions.
• The AP must have all keys used by clients for station‐to‐AP transmit so that it can de‐code the station
transmissions.
• The same key must occupy the same slot on all nodes (AP and clients). For example if the AP defines
abc123 key as WEP key 3, then the client stations must define that same string as WEP key 3.
• Client stations can use different keys to transmit data to the access point. (Or they can all use the same
key, but this is less secure because it means one station can decrypt the data being sent by another.)
• On some wireless client software, you can configure multiple WEP keys and define a client station
“transfer key index”, and then set the stations to encrypt the data they transmit using different keys. This
ensures that neighboring APs cannot decode each other’s transmissions.
• You cannot mix 64‐bit and 128‐bit WEP keys between the access point and its client stations.
IEEE 802.1X
IEEE 802.1X is the standard defining port‐based authentication and infrastructure for doing key management.
Extensible Authentication Protocol (EAP) messages sent over an IEEE 802.11 wireless network using a protocol
called EAP Encapsulation Over LANs (EAPOL). IEEE 802.1X provides dynamically‐generated keys that are
periodically refreshed. An RC4 stream cipher is used to encrypt the frame body and cyclic redundancy checking
(CRC) of each 802.11 frame.
This mode requires the use of an external RADIUS server to authenticate users. The AP requires a RADIUS
server capable of EAP, such as the Microsoft Internet Authentication Server. To work with Windows clients, the
authentication server must support Protected EAP (PEAP) and MSCHAP V2.
You can use any of a variety of authentication methods that the IEEE 802.1X mode supports, including
certificates, Kerberos, and public key authentication. You must configure the client stations to use the same
authentication method the AP uses.

The Wireless Distribution System (WDS) allows you to connect multiple UAPs. With WDS, APs communicate
with one another without wires in a standardized way. This capability is critical in providing a seamless
experience for roaming clients and for managing multiple wireless networks. It can also simplify the network
infrastructure by reducing the amount of cabling required. You can configure the AP in point‐to‐point or point‐
to‐multipoint bridge mode based on the number of links to connect.
In the point‐to‐point mode, the AP accepts client associations and communicates with wireless clients and
other repeaters. The AP forwards all traffic meant for the other network over the tunnel that is established
between the APs. The bridge does not add to the hop count. It functions as a simple OSI layer 2 network device.
In the point‐to‐multipoint bridge mode, one AP acts as the common link between multiple APs. In this mode,
the central AP accepts client associations and communicates with the clients and other repeaters. All other APs
associate only with the central AP that forwards the packets to the appropriate wireless bridge for routing
purposes.
The UAP can also act as a repeater. In this mode, the AP serves as a connection between two APs that might
be too far apart to be within cell range. When acting as a repeater, the AP does not have a wired connection to
the LAN and repeats signals by using the wireless connection. No special configuration is required for the AP
to function as a repeater, and there are no repeater mode settings. Wireless clients can still connect to an AP
that is operating as a repeater.
Note: When you move an AP from Standalone Mode to Managed Mode, WDS is disabled. In Managed
Mode, you configure the AP by using the D‐Link Unified Wireless Switch. The Administrator UI, as well
as Telnet, SSH, and SNMP access are disabled when the AP is in Managed Mode.
To specify the details of traffic exchange from this access point to others, click the WDS tab.

Configuring the Wireless Distribution System (WDS)
Figure 21: Configuring WDS Settings
Before you configure WDS on the AP, note the following guidelines:
• When using WDS, be sure to configure WDS settings on both APs participating in the WDS link.
• You can have only one WDS link between any pair of APs. That is, a remote MAC address may appear only
once on the WDS page for a particular AP.
• Both APs participating in a WDS link must be on the same Radio channel and using the same IEEE 802.11
mode. (See “Modifying Radio Settings” on page 58 for information on configuring the Radio mode and
channel.)
• When 802.11h is operational, setting up two WDS links can be difficult. See “Using the 802.11h Wireless
Mode” on page 57.
• If you use WPA encryption on the WDS link over radio 1, VAP0 of radio 1 must use WPA Personal or WPA
Enterprise as the security mode. If you use WPA on a WDS link over radio 2, VAP0 of radio 2 must use WPA
Personal or WPA Enterprise as the security mode.

For each WDS link on a two‐radio AP, the Local Address reflects the MAC address for the
internal interface on the selected radio (Radio One on wlan0 or Radio Two on wlan1).
Specify the MAC address of the destination AP; that is, the AP on the other end of the
WDS link to which data will be sent or handed‐off and from which data will be received.
Click the drop‐down arrow to the right of the Remote Address field to see a list of all the
available MAC Addresses and their associated SSIDs on the network. Select the
appropriate MAC address from the list.
NOTE: The SSID displayed in the drop‐down list is simply to help you identify the correct
MAC Address for the destination AP. This SSID is a separate SSID to that which you set for
the WDS link. The two do not (and should not) be the same value or name.
You can use no encryption, WEP, or WPA (PSK) on the WDS link.
If you are unconcerned about security issues on the WDS link you may decide not to set
any type of encryption. Alternatively, if you have security concerns you can choose
between Static WEP and WPA (PSK). In WPA (PSK) mode, the AP uses WPA2‐PSK with
CCMP (AES) encryption over the WDS link.
NOTE: In order to configure WPA‐PSK on any WDS link, VAP0 of the selected radio must
be configured for WPA‐PSK or WPA‐Enterprise.

Controlling Access by MAC Authentication
Note: After you configure the WDS settings, you must click Apply to apply the changes and to save the
settings. Changing some settings might cause the AP to stop and restart system processes. If this
happens, wireless clients will temporarily lose connectivity. We recommend that you change AP
settings when WLAN traffic is low.
Controlling Access by MAC Authentication
A Media Access Control (MAC) address is a hardware address that uniquely identifies each node of a network.
All IEEE 802 network devices share a common 48‐bit MAC address format, usually displayed as a string of 12
hexadecimal digits separated by colons, for example 00:DC:BA:09:87:65. Each wireless network interface
card (NIC) used by a wireless client has a unique MAC address.
You can use the Administrator UI on the AP or use an external RADIUS server to control access to the network
through the AP based on the MAC address of the wireless client. This feature is called MAC Authentication or
MAC Filtering. To control access, you configure a global list of MAC addresses locally on the AP or on an external
RADIUS server. Then, you set a filter to specify whether the clients with those MAC addresses are allowed or
denied access to the network. When a wireless client attempts to associate with an AP, the AP looks up the
MAC address of the client in the local Stations List or on the RADIUS server. If it is found, the global allow or
deny setting is applied. If it is not found, the opposite is applied.
On the VAP page, the MAC Authentication Type setting controls whether the AP uses the station list configured
locally on the MAC Authentication page or the external RADIUS server. The Allow/Block filter setting on the
MAC Authentication page determines whether the clients in the station list (local or RADIUS) can access the
network through the AP. For more information about setting the MAC authentication type, see “Virtual Access
Point Settings” on page 70.
Configuring a MAC Filter and Station List on the AP
The MAC Authentication page allows you to control access to UAP based on MAC addresses. Based on how
you set the filter, you can allow only client stations with a listed MAC address or deny access to the stations
listed.
When you enable MAC Authentication and specify a list of approved MAC addresses, only clients with a listed
MAC address can access the network. If you specify MAC addresses to deny, all clients can access the network
except for the clients on the deny list.
To enable filtering by MAC address, click the MAC Authentication tab.

Filter
To set the MAC Address Filter, select one of the following options:
• Allow only stations in the list. Any station that is not in the Stations List is denied
access to the network through the AP.
• Block all stations in list. Only the stations that appear in the list are denied access to
the network through the AP. All other stations are permitted access.
Note: The filter you select is applied to the clients in the station list, regardless of
whether that station list is local or on the RADIUS server.
This is the local list of clients that are either permitted or denied access to the network
through the AP. To add a MAC Address to the local Stations List, enter its 48‐bit MAC
address into the lower text boxes, then click Add.
To remove a MAC Address from the Stations List, select its 48‐bit MAC address, then click
Remove.
The stations in the list will either be allowed or denied access based on how you set the
filter in the previous field.
Note: If the MAC authentication type for the VAP is set to Local, the AP uses the Stations
List to permit or deny the clients access to the network. If the MAC authentication type
is set to RADIUS, the AP ignores the MAC addresses configured in this list and uses the
list that is stored on the RADIUS server. The MAC authentication type is set on the VAP
configuration page.

Managed Access Point Overview
Managed Access Point Overview
The UAP can operate in two modes: Standalone Mode or Managed Mode. In Standalone Mode, the UAP acts
as an individual AP in the network, and you manage it by using the Administrator Web User Interface (UI), CLI,
or SNMP. In Managed Mode, the UAP is part of the D‐Link Unified Wired and Wireless System, and you manage
it by using the D‐Link Unified Wireless Switch. If an AP is in Managed Mode, the Administrator Web UI, Telnet,
SSH, and SNMP services are disabled.
On the UAP, you can configure the IP addresses of up to four D‐Link Unified Wireless Switches that can manage
it. In order to manage the AP, the switch and AP must discover each other. There are multiple ways for a switch
to discover an AP. Adding the IP address of the switch to the AP while it is in Standalone Mode is one way to
enable switch‐to‐AP discovery.
Transitioning Between Modes
Every 30 seconds, the D‐Link Unified Wireless Switch sends a keepalive message to all of the access points it
manages. Each AP checks for the keepalive messages on the SSL TCP connection. As long as the AP maintains
communication with the switch through the keepalive messages, it remains in Managed Mode.
If the AP does not receive a message within 45 seconds of the last keepalive message, the AP assumes the
switch has failed and terminates its TCP connection to the switch, and the AP enters Standalone Mode.
Once the AP transitions to Standalone Mode, it continues to forward traffic without any loss. The AP uses the
configuration on the VAPs configured in VLAN Forwarding mode (the standard, non‐tunneled mode).
While the AP is in Standalone Mode, you can manage it by using the Web interface or the CLI (through Telnet
or SSH).
For any clients that are connected to the AP through tunneled VAPs, the AP sends disassociate messages and
disables the tunneled VAPs.
As long as the Managed AP Administrative Mode is set to Enabled, as Figure 24 on page 90 shows, the AP starts
discovery procedures. If the AP establishes a connection with a wireless switch, which may or may not be the
same switch it was connected to before, the switch sends the AP its configuration and the AP sends the wireless
switch information about all currently associated clients.
After the configuration from the switch is applied, the AP radio(s) restart. Client traffic is briefly interrupted
until the radio(s) are up and the clients are re‐associated.

Configuring SNMP on the Access Point
Simple Network Management Protocol (SNMP) defines a standard for recording, storing, and sharing
information about network devices. SNMP facilitates network management, troubleshooting, and
maintenance. The AP supports SNMP versions 1, 2, and 3. Unless specifically noted, all configuration
parameters on this page apply to SNMPv1 and SNMPv2c only.
Key components of any SNMP‐managed network are managed devices, SNMP agents, and a management
system. The agents store data about their devices in Management Information Bases (MIBs) and return this
data to the SNMP manager when requested. Managed devices can be network nodes such as APs, routers,
switches, bridges, hubs, servers, or printers.
The UAP can function as an SNMP managed device for seamless integration into network management systems
such as HP OpenView.
From the SNMP page under the Services heading, you can start or stop control of SNMP agents, configure
community passwords, access MIBs, and configure SNMP Trap destinations.
From the pages under the SNMPv3 heading, you can manage SNMPv3 users and their security levels and define
access control to the SNMP MIBs. For information about how to configure SNMPv3 views, groups, users, and
targets, see “Configuring SNMPv3” on page 111.

As with community names, this provides a level of security on SNMP settings. The
SNMP agent will only accept requests from the hostname or subnet specified here.
To specify a subnet, enter one or more subnetwork address ranges in the form
address/mask_length where address is an IP address and mask_length is the
number of mask bits. Both formats address/mask and address/
mask_length are supported. Individual hosts can be provided for this, i.e. I.P
Address or Hostname. For example, if you enter a range of 192.168.1.0/24 this
specifies a subnetwork with address 192.168.1.0 and a subnet mask of
255.255.255.0.
The address range is used to specify the subnet of the designated NMS. Only
machines with IP addresses in this range are permitted to execute get and set
requests on the managed device. Given the example above, the machines with
addresses from 192.168.1.1 through 192.168.1.254 can execute SNMP
commands on the device. (The address identified by suffix .0 in a subnetwork range
is always reserved for the subnet address, and the address identified by .255 in the
range is always reserved for the broadcast address).
As another example, if you enter a range of 10.10.1.128/25 machines with IP
addresses from 10.10.1.129 through 10.10.1.254 can execute SNMP
requests on managed devices. In this example, 10.10.1.128 is the network
address and 10.10.1.255 is the broadcast address. 126 addresses would be
designated.

Configuring Quality of Service
Configuring Quality of Service
Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased
throughput and better performance of differentiated wireless traffic like Voice‐over‐IP (VoIP), other types of
audio, video, and streaming media, as well as traditional IP data over the UAP.
Configuring QoS on the UAP consists of setting parameters on existing queues for different types of wireless
traffic, and effectively specifying minimum and maximum wait times (through Contention Windows) for
transmission. The settings described here apply to data transmission behavior on the AP only, not to that of
the client stations.
AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the AP to the client
station.
Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to
the AP.
The default values for the AP and station EDCA parameters are those suggested by the Wi‐Fi Alliance in the
WMM specification. In normal use these values should not need to be changed. Changing these values will
affect the QoS provided.
Note: On the DWL‐6600AP and DWL‐8600AP, the QoS settings apply to both radios, but the traffic for
each radio is queued independently.
To set up queues for QoS, click the QoS tab under the Services heading and configure settings as described in
Table 40 on page 103.

as VoIP and streaming media are automatically sent to this queue.
• Data 1(Video) — High priority queue, minimum delay. Time‐sensitive video data
is automatically sent to this queue.
• Data 2 (best effort) — Medium priority queue, medium throughput and delay.
Most traditional IP data is sent to this queue.
• Data 3 (Background) — Lowest priority queue, high throughput. Bulk data that
requires maximum throughput and is not time‐sensitive is sent to this queue
(FTP data, for example).
The Arbitration Inter‐Frame Spacing (AIFS) specifies a wait time for data frames.
The wait time is measured in slots. Valid values for AIFS are 1 through 255.

This parameter is input to the algorithm that determines the initial random backoff
wait time (window) for retry of a transmission.
The value specified for Minimum Contention Window is the upper limit (in
milliseconds) of a range from which the initial random backoff wait time is
determined.
The first random number generated will be a number between 0 and the number
specified here.
If the first random backoff wait time expires before the data frame is sent, a retry
counter is incremented and the random backoff value (window) is doubled.
Doubling will continue until the size of the random backoff value reaches the
number defined in the Maximum Contention Window.
Valid values for cwMin are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for
cwMin must be lower than the value for cwMax.

cwMax must be higher than the value for cwMin.
Max. Burst Length
The Max. Burst Length is an AP EDCA parameter and only applies to traffic flowing
from the AP to the client station.
This value specifies (in milliseconds) the maximum burst length allowed for packet
bursts on the wireless network. A packet burst is a collection of multiple frames
transmitted without header information. The decreased overhead results in higher
throughput and better performance.
Valid values for maximum burst length are 0.0 through 999.

Enabling the Time Settings (NTP)
Enabling the Time Settings (NTP)
Use the Time Settings page to specify the Network Time Protocol (NTP) server to use to provide time and date
information to the AP or to configure the time and date information manually.
NTP is an Internet standard protocol that synchronizes computer clock times on your network. NTP servers
transmit Coordinated Universal Time (UTC, also known as Greenwich Mean Time) to their client systems. NTP
sends periodic time requests to servers, using the returned time stamp to adjust its clock. The timestamp is
used to indicate the date and time of each event in log messages.
See http://www.ntp.org for more information about NTP.
To set the system time either manually or by specifying the address of the NTP server for the AP to use, click

Configuring SNMPv3 Views
A MIB view is combination of a set of view subtrees or a family of view subtrees where each view subtree is a
subtree within the managed object naming tree. You can create MIB views to control the OID range that
SNMPv3 users can access.
A MIB view called "all" is created by default in the system. This view contains all management objects
supported by the system.
Note: If you create an excluded view subtree, create a corresponding included entry with the same
view name to allow subtrees outside of the excluded subtree to be included. For example, to create a
view that excludes the subtree 1.3.6.1.4, create an excluded entry with the OID 1.3.6.1.4. Then, create
an included entry with OID .1 with the same view name.

For example, the system subtree is specified by the OID string .1.3.6.1.2.1.1.
The OID mask is 47 characters in length. The format of the OID mask is xx.xx.xx (.)... or
xx:xx:xx.... (:) and is 16 octets in length. Each octet is 2 hexadecimal characters separated
by either . (period) or : (colon). Only hex characters are accepted in this field. For
example, OID mask FA.80 is 11111010.10000000.
A family mask is used to define a family of view subtrees. The family mask indicates which
sub‐identifiers of the associated family OID string are significant to the family's
definition.
A family of view subtrees allows control access to one row in a table, in a more efficient
manner.

Configuring SNMPv3 Groups
Configuring SNMPv3 Groups
SNMPv3 groups allow you to combine users into groups of different authorization and access privileges.
By default, the UAP has two groups:
• RO — A read‐only group using authentication and data encryption. Users in this group use an MD5 key/
password for authentication and a DES key/password for encryption. Both the MD5 and DES key/
passwords must be defined. By default, users of this group will have read only access to the default all MIB
view, which can be modified by the user.
• RW — A read/write group using authentication and data encryption. Users in this group use an MD5 key/
password for authentication and a DES key/password for encryption. Both the MD5 and DES key/
passwords must be defined. By default, users of this group will have read and write access to the default
all MIB view, which can be modified by the user.
RW and RO groups are defined by default.
Note: The UAP supports maximum of eight groups.
To define additional groups, navigate to the SNMPv3 Groups page and configure the settings that Table 44 on

Packet Capture Configuration and Settings
Wireless packet capture operates in two modes:
• Capture file mode
• Remote capture mode
For capture file mode, captured packets are stored in a file on the Access Point. The AP can transfer the file to
a TFTP server. The file is formatted in pcap format and can be examined using tools such as Wireshark and
OmniPeek.
For remote capture mode, the captured packets are redirected in real time to an external PC running the
Wireshark® tool.
The AP can capture the following types of packets:
• 802.11 packets received and transmitted on radio interfaces. Packets captured on radio interfaces include
the 802.11 header.
• 802.3 packets received and transmitted on the Ethernet interface.
• 802.3 packets received and transmitted on the internal logical interfaces such as VAPs and WDS interfaces.
From the Packet Capture Configuration and Settings page, you can:
• View the current packet capture status.
• Configure packet capture parameters.
• Configure packet file capture.
• Configure a remote capture port.
• Download a packet capture file.

Remote Packet Capture
Remote Packet Capture allows you to specify a remote port as the destination for packet captures. This feature
works in conjunction with the Wireshark network analyzer tool for Windows. A packet capture server runs on
the AP and sends the captured packets via a TCP connection to the Wireshark tool.
A Windows PC running the Wireshark tool allows you to display, log, and analyze captured traffic.
When the remote capture mode is in use, the AP doesn't store any captured data locally in its file system.
Your can trace up to five interfaces on the AP at the same time. However, you must start a separate Wireshark
session for each interface. You can configure the IP port number used for connecting Wireshark to the AP. The
default port number is 2002. The system uses 5 consecutive port numbers starting with the configured port for
the packet capture sessions.
If a firewall is installed between the Wireshark PC and the AP, these ports must be allowed to pass through the
firewall. The firewall must also be configured to allow the Wireshark PC to initiate TCP connection to the AP.

Unified Access Point Administrator’s Guide

Unified Access Point Administrator’s Guide
Packet Capture Configuration and Settings
To configure Wireshark to use the AP as the source for captured packets, you must specify the remote interface
in the "Capture Options" menu. For example to capture packets on an AP with IP address 192.168.1.10 on radio
1 using the default IP port, specify the following interface:
rpcap://192.168.1.10/radio1
To capture packets on the Ethernet interface of the AP and VAP0 on radio 1 using IP port 58000, start two
Wireshark sessions and specify the following interfaces:
rpcap://192.168.1.10:58000/eth0
rpcap://192.168.1.10:58000/wlan0
When you are capturing traffic on the radio interface, you can disable beacon capture, but other 802.11 control
frames are still sent to Wireshark. You can set up a display filter to show only:
• Data frames in the trace
• Traffic on specific BSSIDs
• Traffic between two clients
Some examples of useful display filters are:
• Exclude beacons and ACK/RTS/CTS frames:
!(wlan.fc.type_subtype == 8 || wlan.fc.type == 1)
• Data frames only:
wlan.fc.type == 2
• Traffic on a specific BSSID:
wlan.bssid == 00:02:bc:00:17:d0
• All traffic to and from a specific client:
wlan.addr == 00:00:e8:4e:5f:8e
In remote capture mode, traffic is sent to the PC running Wireshark via one of the network interfaces.
Depending on where the Wireshark tool is located the traffic can be sent on an Ethernet interface or one of the
radios. In order to avoid a traffic flood caused by tracing the trace packets, the AP automatically installs a
capture filter to filter out all packets destined to the Wireshark application. For example if the Wireshark IP port
is configured to be 58000 then the following capture filter is automatically installed on the AP:
not portrange 58000‐58004.
Enabling the packet capture feature impacts performance of the AP and can create a security issue
(unauthorized clients may be able to connect to the AP and trace user data). The AP performance is negatively
impacted even if there is no active Wireshark session with the AP. The performance is negatively impacted to
a greater extent when packet capture is in progress.
Due to performance and security issues, the packet capture mode is not saved in NVRAM on the AP; if the AP
resets, the capture mode is disabled and the you must re‐enable it in order to resume capturing traffic. Packet
capture parameters (other than mode) are saved in NVRAM.

Packet Capture Configuration and Settings
In order to minimize performance impact on the AP while traffic capture is in progress, you should install
capture filters to limit which traffic is sent to the Wireshark tool. When capturing 802.11 traffic, large portion
of the captured frames tend to be beacons (typically sent every 100ms by all Access Points). Although
Wireshark supports a display filter for beacon frames, it does not support a capture filter to prevent the AP
from forwarding captured beacon packets to the Wireshark tool. In order to reduce performance impact of
capturing the 802.11 beacons, you can disable the capture beacons mode.
The remote packet capture facility is a standard feature of the Wireshark tool for Windows.
Note: Remote packet capture is not standard on the Linux version of Wireshark; the Linux version
doesn't work with the AP.
Wireshark is an open source tool and is available for free; it can be downloaded from http://
www.wireshark.org.

Packet Capture File Download allows you to download the capture file by TFTP to a configured TFTP server or
by HTTP(S) to a PC. The captured packets are stored in file /tmp/apcapture.pcap on the AP. A capture is
automatically stopped when the capture file download command is triggered.
Because the capture file is located in the RAM file system, it disappears if the AP is reset.

Configuring Client Quality of Service
Section 8: Configuring Client Quality of Service
This section describes how to configure QoS settings that affect traffic from the wireless clients to the AP. By
using the UAP Client QoS features, you can limit bandwidth and apply ACLs and DiffServ policies to the wireless
interface. If a VAP uses WPA Enterprise security to authenticate clients, you can configure the RADIUS server
to provide per‐client QoS information.
This section describes the following features:
• “Configuring VAP QoS Parameters”
• “Managing Client QoS ACLs”
• “Creating a DiffServ Class Map”
• “Creating a DiffServ Policy Map”
• “Configuring RADIUS‐Assigned Client QoS Parameters”
Note: The web‐based UI images in this section show the DWL‐8600AP administration pages. Pages
for the DWL‐3600AP will not display information for Radio 2 because it has only one radio.
Configuring VAP QoS Parameters
The client QoS features on the UAP provide additional control over certain QoS aspects of wireless clients that
connect to the network, such as the amount of bandwidth an individual client is allowed to send and receive.
To control general categories of traffic, such as HTTP traffic or traffic from a specific subnet, you can configure
ACLs and assign them to one or more VAPs.
In addition to controlling general traffic categories, Client QoS allows you to configure per‐client conditioning
of various micro‐flows through Differentiated Services (DiffServ). DiffServ policies are a useful tool for
establishing general micro‐flow definition and treatment characteristics that can be applied to each wireless
client, both inbound and outbound, when it is authenticated on the network.
From the VAP QoS Parameters page, you can enable the Client QoS feature, specify client bandwidth limits,
and select the ACLs and DiffServ policies to use as default values for clients associated with the VAP when the
client does not have their own attributes defined by a RADIUS server.
To configure the Client QoS administrative mode and to configure the QoS settings for a VAP, click the VAP QoS
Parameters tab.

Managing Client QoS ACLs
Managing Client QoS ACLs
ACLs are a collection of permit and deny conditions, called rules, that provide security by blocking unauthorized
users and allowing authorized users to access specific resources. ACLs can block any unwarranted attempts to
reach network resources.
The UAP supports up to 50 IPv4, IPv6, and MAC ACLs.
IPv4 and IPv6 ACLs
IP ACLs classify traffic for Layers 3 and 4.
Each ACL is a set of up to 10 rules applied to traffic sent from a wireless client or to be received by a wireless
client. Each rule specifies whether the contents of a given field should be used to permit or deny access to the
network. Rules can be based on various criteria and may apply to one ore more fields within a packet, such as
the source or destination IP address, the source or destination L4 port, or the protocol carried in the packet.
MAC ACLs
MAC ACLs are Layer 2 ACLs. You can configure the rules to inspect fields of a frame such as the source or
destination MAC address, the VLAN ID, or the Class of Service 802.1p priority. When a frame enters or exits the
AP port (depending on whether the ACL is applied in the up or down direction), the AP inspects the frame and
checks the ACL rules against the content of the frame. If any of the rules match the content, a permit or deny
action is taken on the frame.
ACL Configuration Process
Configure ACLs and rules on the Client QoS ACL page (steps 1 – 5), and then apply the rules to a specified VAP
on the AP QoS Parameters page (step 6).
Use the following general steps to configure ACLs:
1. Specify a name for the ACL.
2. Select the type of ACL to add.
3. Add the ACL
4. Add new rules to the ACL.
5. Configure the match criteria for the rules.
6. Apply the ACL to one or more VAPs.
For an example of how to configure an ACL, see “ACL Configuration” on page 174
To configure an ACL, click the Client QoS ACL tab.

• When you select Deny, the rule blocks all traffic that meets the rule criteria from
entering or exiting the AP (depending on the ACL direction you select). Traffic
that does not meet the criteria is forwarded unless this rule is the final rule.
Because there is an implicit deny all rule at the end of every ACL, traffic that is
not explicitly permitted is dropped.

The wild card masks determines which bits are used and which bits are ignored. A
wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of
0.0.0.0 indicates that all of the bits are important. This field is required when Source
IP Address is checked.
A wild card mask is in essence the inverse of a subnet mask. For example, To match
the criteria to a single host address, use a wildcard mask of 0.0.0.0. To match the
criteria to a 24‐bit subnet (for example 192.168.10.0/24), use a wild card mask of
0.0.0.255.

Creating a DiffServ Class Map
Creating a DiffServ Class Map
The Client QoS feature contains Differentiated Services (DiffServ) support that allows traffic to be classified into
streams and given certain QoS treatment in accordance with defined per‐hop behaviors.
Standard IP‐based networks are designed to provide best effort data delivery service. Best effort service implies
that the network delivers the data in a timely fashion, although there is no guarantee that it will. During times
of congestion, packets may be delayed, sent sporadically, or dropped. For typical Internet applications, such as
e‐mail and file transfer, a slight degradation in service is acceptable and in many cases unnoticeable. However,
on applications with strict timing requirements, such as voice or multimedia, any degradation of service has
undesirable effects.
By classifying the traffic and creating policies that define how to handle these traffic classes, you can make sure
that time‐sensitive traffic is given precedence over other traffic.
The UAP supports up to 50 Class Maps.
Defining DiffServ
To use DiffServ for Client QoS, use the Class Map and Policy Map pages to define the following categories and
their criteria:
• Class: create classes and define class criteria
• Policy: create policies, associate classes with policies, and define policy statements
Once you define the class and associate it with a policy, apply the policy to a specified VAP on the VAP QoS
Parameters page.
Packets are classified and processed based on defined criteria. The classification criteria is defined by a class.
The processing is defined by a policy's attributes. Policy attributes may be defined on a per‐class instance basis,
and it is these attributes that are applied when a match occurs. A policy can contain multiple classes. When the
policy is active, the actions taken depend on which class matches the packet.
Packet processing begins by testing the class match criteria for a packet. A policy is applied to a packet when a
class match within that policy is found. DiffServ is supported for IPv4 and IPv6 packets.
Use the Class Map page to add a new Diffserv class name, or to rename or delete an existing class, and define
the criteria to associate with the DiffServ class.
To configure a DiffServ Class Map, click the Class Map tab.
Note: The Class Map page displays the Match Criteria Configuration fields only if a Class Map has been
created. To create a Class Map, enter a name in the Class Map Name field and click Add Class Map.

Configuring RADIUS‐Assigned Client QoS Parameters
If a VAP is configured to use WPA Enterprise security, you can include client QoS information in the client
database on the RADIUS server. When a client successfully authenticates, the RADIUS server can include
bandwidth limits and identify the ACLs and DiffServ policies to apply to the specific wireless client. ACLs and
DiffServ policies referenced in the RADIUS client database must match the names of the ACLs and DiffServ
policies configured on the AP to be successfully applied to the wireless clients.
Table 57 describes the QoS attributes that can be included in the client's RADIUS server entry. If a wireless
client successfully authenticates using WPA Enterprise, each QoS RADIUS attribute that exists for the client is
sent to the AP for processing. The attributes are optional and do not need to be present in the client entry. If
the attribute is not present, the Client QoS setting on the AP is used.

Clustering Multiple APs
Section 9: Clustering Multiple APs
The UAP supports AP clusters. A cluster provides a single point of administration and lets you view, deploy,
configure, and secure the wireless network as a single entity rather than a series of separate wireless devices.
Managing Access Points in the Cluster
The AP cluster is a dynamic, configuration‐aware group of APs in the same subnet of a network. Each cluster
can have up to 16 members. Only one cluster per wireless network is supported; however, a network subnet
can have multiple clusters. Clusters can share various configuration information, such as VAP settings and QoS
queue parameters.
A cluster can be formed between two APs if the following conditions are met:
• The APs use the same radio mode (for example, radio 1 uses 802.11g)
• The APs are connected on the same bridged segment.
• The APs joining the cluster have the same Cluster Name.
• Clustering mode is enabled on both APs.
Note: For two APs to be in the same cluster, they do not need to have the same number of radios;
however, the supported capabilities of the radios should be same.
Note: The web‐based UI images in this section show the DWL‐8600AP administration pages. Pages
for the DWL‐3600AP will not display information for Radio 2 because it has only one radio.
Clustering Single and Dual Radio APs
Clustering of single‐ and dual‐radios is not supported. A cluster can contain a mix if DWL‐6600AP and
DWL‐8600AP access points, but this cluster should not contain any DWL‐3600APs.
Viewing and Configuring Cluster Members
The Access Points page allows you to start or stop clustering on an AP, view the cluster members, and configure
the location and cluster name for a cluster member. From the Access Points page, you can also click the IP
address of each cluster member to navigate to configuration settings and data on an access point in the cluster.
To view information about cluster members and to configure the location and cluster of an individual member,
click the Access Points tab.

Adding an Access Point to a Cluster
To add an access point that is currently in standalone mode back into a cluster, do the following.
1. Go to the Administration Web pages for the standalone access point.
2. Click the Cluster > Access Points link in the Administration pages for the stand‐alone access point.
The Access Points page for a standalone access point indicates that the current mode is standalone.
3. Type the name or location of the AP in the Location field to identify the AP within the cluster.
4. Type the name of the cluster for the AP to join in the Cluster Name field.
5. Click Start Clustering.
The access point is now a cluster member. Its Status (Mode) on the Cluster > Access Points page now
indicates Cluster instead of Not Clustered.
Navigating to Configuration Information for a Specific AP
In general, the UAP is designed for central management of clustered access points. For access points in a cluster,
all access points in the cluster reflect the same configuration. In this case, it does not matter which access point
you actually connect to for administration.
There may be situations, however, when you want to view or manage information on a particular access point.
For example, you might want to check status information such as client associations or events for an access
point. In this case, you can navigate to the Administration Web interface for individual access points by clicking
the IP address links on the Access Points page.
All clustered access points are shown on the Cluster > Access Points page. To navigate to clustered access
points, you can simply click on the IP address for a specific cluster member shown in the list.
Navigating to an AP by Using its IP Address in a URL
You can also link to the Administration Web pages of a specific access point, by entering the IP address for that
access point as a URL directly into a Web browser address bar in the following form:
http://IPAddressOfAccessPoint
where IPAddressOfAccessPoint is the address of the particular access point you want to monitor or configure.

Managing Cluster Sessions
Managing Cluster Sessions
The Sessions page shows information about client stations associated with access points in the cluster. Each
client is identified by its MAC address, along with the AP (location) to which it is currently connected.
To view a particular statistic for client sessions, select an item from the Display drop‐down list and click Go. You
can view information about idle time, data rate, signal strength and so on; all of which are described in detail
in the table below.
A session in this context is the period of time in which a user on a client device (station) with a unique MAC
address maintains a connection with the wireless network. The session begins when the client logs on to the
network, and the session ends when the client either logs off intentionally or loses the connection for some
other reason.
Note: A session is not the same as an association, which describes a client connection to a particular
access point. A client network connection can shift from one clustered AP to another within the
context of the same session. A client station can roam between APs and maintain the session.
To manage sessions associated with the cluster, click Cluster > Sessions.

Configuring and Viewing Channel Management Settings
When Channel Management is enabled, the UAP automatically assigns radio channels used by clustered access
points. The automatic channel assignment reduces mutual interference (or interference with other access
points outside of its cluster) and maximizes Wi‐Fi bandwidth to help maintain the efficiency of communication
over the wireless network.
You must start channel management to get automatic channel assignments; it is disabled by default on a new
AP.
At a specified interval, the Channel Manager maps APs to channel use and measures interference levels in the
cluster. If significant channel interference is detected, the Channel Manager automatically re‐assigns some or
all of the APs to new channels per an efficiency algorithm (or automated channel plan). If the Channel Manager
determines that a change is necessary, that information is sent to all members of the cluster and a syslog
message is generated indicating the sender AP, new and old channel assignments.
The Channel Management page shows previous, current, and planned channel assignments for clustered
access points. By default, automatic channel assignment is disabled. You can start channel management to
optimize channel usage across the cluster on a scheduled interval.
To configure and view the channel assignments for the cluster members, click the Channel Management tab.

management. By using the Advanced settings on the page, you can modify the interference reduction potential
that triggers channel re‐assignment, change the schedule for automatic updates, and re‐configure the channel
set used for assignments.
Stopping/Starting Automatic Channel Assignment
By default, automatic channel assignment is disabled (off).
Note: Channel Management overrides the default cluster behavior, which is to synchronize radio
channels of all APs across a cluster. When Channel Management is enabled, the radio Channel is
not synced across the cluster to other APs.
• Click Start to resume automatic channel assignment.
When automatic channel assignment is enabled, the Channel Manager periodically maps radio channels
used by clustered access points and, if necessary, re‐assigns channels on clustered APs to reduce
interference (with cluster members or other APs outside the cluster).
• Click Stop to stop automatic channel assignment. (No channel usage maps or channel re‐assignments will
be made. Only manual updates will affect the channel assignment.)

Viewing Current Channel Assignments and Setting Locks
The Current Channel Assignments section shows a list of all access points in the cluster by IP Address. The
display shows the band on which each AP is broadcasting (a/b/g/n), the current channel used by each AP, and
an option to lock an AP on its current radio channel so that it cannot be re‐assigned to another.

Click Locked to force the access point to remain on the current channel.
When Locked is selected (enabled) for an access point, automated channel management
plans will not re‐assign the AP to a different channel as a part of the optimization strategy.
Instead, APs with locked channels will be factored in as requirements for the plan.
If you click Apply, you will see that locked APs show the same channel for the Current
Channel and Proposed Channel fields. Locked APs will keep their current channels.
Viewing the Last Proposed Set of Changes
The Proposed Channel Assignments shows the last channel plan. The plan lists all access points in the cluster
by IP Address, and shows the current and proposed channels for each AP. Locked channels will not be re‐
assigned and the optimization of channel distribution among APs will take into account the fact that locked APs
must remain on their current channels. APs that are not locked may be assigned to different channels than they
were previously using, depending on the results of the plan.

Configuring Advanced Settings
The advanced settings allow you to customize and schedule the channel plan for the cluster. If you use Channel
Management as provided (without updating Advanced Settings), channels are automatically fine‐tuned once
every hour if interference can be reduced by 25 percent or more. Channels will be re‐assigned even if the
network is busy. The appropriate channel sets will be used (b/g for APs using IEEE 802.11b/g and a for APs using
IEEE 802.11a).
The default settings are designed to satisfy most scenarios where you would need to implement channel
management.
Use Advanced Settings to modify the interference reduction potential that triggers channel re‐assignment,
change the schedule for automatic updates, and re‐configure the channel set used for assignments. If there are

Network Name, IP Address, MAC address) along with radio statistics (signal strength, channel, beacon interval).
You can click on an AP to get additional statistics about the APs in radio range of the currently selected AP.
The Wireless Neighborhood view can help you:
• Detect and locate unexpected (or rogue) access points in a wireless domain so that you can take action to
limit associated risks
• Verify coverage expectations. By assessing which APs are visible at what signal strength from other APs,
you can verify that the deployment meets your planning goals.
• Detect faults. Unexpected changes in the coverage pattern are evident at a glance in the color coded table.

at the top of the list with a heavy bar above and include a location indicator.
The colored bars to the right of each AP in the Neighbors list shows the signal
strength for each of the neighbor APs as detected by the cluster member whose IP
address is shown at the top of the column.
The color of the bar indicates the signal strength:
• Dark Blue Bar — A dark blue bar and a high signal strength number (for example
50) indicates good signal strength detected from the Neighbor seen by the AP
whose IP address is listed above that column.
• Lighter Blue Bar — A lighter blue bar and a lower signal strength number (for
example 20 or lower) indicates medium or weak signal strength from the
Neighbor seen by the AP whose IP address is listed above that column
• White Bar — A white bar and the number 0 indicates that a neighboring AP that
was detected by one of the cluster members cannot be detected by the AP
whose IP address if listed above that column.
• Light Gray Bar — A light gray bar and no signal strength number indicates a
Neighbor that is detected by other cluster members but not by the AP whose
IP address is listed above that column.
• Dark Gray Bar — A dark gray bar and no signal strength number indicates this is
the AP whose IP address is listed above that column (since it is not applicable
to show how well the AP can detect itself).

Configuring Client QoS
Clustering APs by Using SNMP
Cluster configuration by using SNMP is not supported.
Configuring Client QoS
This example shows how to enable client QoS, configure an ACL and a DiffServ policy on the AP, and to apply
the ACL and the Policy to traffic transmitted from clients associated with VAP 2 and received by the AP.
The IPv4 ACL is named acl1 and contains two rules. The first rule allows HTTP traffic from the 192.168.1.0
subnet. The second rule allows all IP traffic from the management station (192.168.1.23). All other traffic is
denied due to the implicit deny all rule at the end of the ACL. The ACL is applied to the inbound interface on
the AP so that packets are checked when the AP receives traffic from associated clients.
The DiffServ policy in this example shows how to establish default DiffServ behavior for clients associating with
the VAP that do not obtain a DiffServ policy name through the RADIUS server. Voice traffic (UDP packets)
received from clients in the 192.168.1.0 subnet that has the VoIP server as its destination address
(192.168.2.200), is marked with the IP DSCP value for expedited forwarding so that it takes priority over other
traffic.

This device has been designed to operate with an antenna having a maximum gain of 5 dBi. Antenna
having a higher gain is strictly prohibited per regulations of Industry Canada. The required antenna
impedance is 50 ohms.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter (IC: 4216A-WL6600APA1 / Model: DWL-6600APA1) has been approved by
Industry Canada to operate with the antenna types listed below with the maximum permissible gain and
required antenna impedance for each antenna type indicated. Antenna types not included in this list,
having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with
this device.
Ce dispositif a été conçu pour fonctionner avec une antenne ayant un gain maximal de 5 dBi. Une antenne
à gain plus élevé est strictement interdite par les règlements d'Industrie Canada. L'impédance d'antenne
