Section 2 - Getting Started
Required Software or Component Description
Wireless Connection to the Network After initial conguration and launch of the rst access point on your
new wireless network, you can make subsequent conguration 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 congured to associate with the UAP.
Web Browser and Operating System Conguration 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.
Note: DWL-3610AP and DWL-6610B1AP support the following web
browsers:
•) Microsoft® Internet Explorer® version 8.x or 9.x (with up-to-date patch
level for either major version)
•) Mozilla® Firefox version 26.0 or later
•) Chrome on Windows (for AP only) version 32.0 or later
Security Settings Ensure that security is disabled on the wireless client used to initially
congure the access point.
Table 2 - Requirements for the Administrator’s Computer
Wireless Client Requirements
The UAP provides wireless access to any client with a properly congured 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.
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, congured to
associate with the UAP.

Section 2 - Getting Started
Required Component Description
Client Security Settings Security should be disabled on the client used to do initial conguration 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 prole to the authentication mode
used by the access point and provide a valid username and password,
certicate, or similar user identity proof. Security modes are Static WEP,
IEEE 802.1X, WPA with RADIUS server, and WPA-PSK.
For information about conguring security on the access point, see “Virtual
Access Point Settings” on page 50.
Table 3 - Requirements for Wireless Clients
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 nd 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 “Conguring the Ethernet
Settings” on page 18 or, by using the Web UI, see “Ethernet Settings” on page 36.
Caution! If you do not have a DHCP server on your internal network, and do not plan to use one,
the rst 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.
Recovering an IP Address
If you experience trouble communicating with the access point, you can recover a static IP address by resetting the AP
conguration to the factory defaults (see “Resetting the Factory Default Conguration” on page 86), 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 nd 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 17.
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.

Section 2 - Getting Started
•) 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 gure.
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 gure. 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 conguration 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 recongure 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).
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
conguration 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
eld of your browser, which is the default IP address of the AP.
•) If you used a DHCP server on your network to automatically congure 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:
•) Connect a serial cable from the administrative computer to the AP and use a terminal emulation program to
access the command-line interface (CLI).
•) 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 eld 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.
4.) When prompted, enter for the user name and for the password, then click .admin admin Logon

•) Review access point description and provide a new administrator password for the access point if you do not
want to use the default password, which is .admin
•) Click the button to activate the wireless network with these new settings. Apply
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 trafc is low.
For information about the elds and conguration options on the Basic Settings page, see “Basic Settings” on
page 16.
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 “Conguring the
Ethernet Settings” on page “Ethernet Settings” on page 18 (CLI) or 36 (Web).
7.) If your network uses VLANs, you might need to congure 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 congure VLAN information, see “Conguring the Ethernet Settings” on page 18

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. For DWL-3610AP and DWL-6610B1AP, it will work with
Microsoft Internet Explorer 8 (IE8).
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 eld: 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 dened as “%6,” type the following address into the IE7 address eld: 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.) Congure 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.

Conguring 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 congure 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 congured 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 congure the Ethernet settings, see “Ethernet Settings” on page
36. You can also use the CLI to congure the Ethernet settings, which the following section describes.

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 ne-tune the AP by modifying
advanced conguration features.
1.) Connect the access point to the LAN.
•) If you congured 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 congured the access point by using a direct cable connection from your computer to the access point,
do the following procedures:
•) Disconnect the cable from the computer and the access point.
•) Connect an Ethernet cable from the access point to the LAN.
•) 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 12.
3.) Secure and congure 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 congure performance settings.
Note: The WLAN AP is not designed for multiple, simultaneous conguration changes. If more
than one administrator is logged onto the Administration Web pages and making changes to the
conguration, there is no guarantee that all conguration changes specied 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
Unied Access Point Administrator’s Guide
Unied Access Point Administrator’s Guide

Section 2 - Getting Started
your LAN. An important next step is to congure security, as described in “Virtual Access Point Settings” on page
50.
Conguring Security on the Wireless Access Point
You congure secure wireless client access by conguring security for each virtual access point (VAP) that you
enable. You can congure 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 congure 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 congure a security option other than
None for the default VAP and for each VAP that you enable.
For information about how to congure the security settings on each VAP, see “Virtual Access Point Settings” on page
50.

•) logging to write system event logs to non-volatile memory so that the events Enable and congure Persistent
are not erased when the system reboots.
•) Set a to determine what category of log messages are displayed.Severity Level
•) 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.
Conguring Persistent Logging Options
If the system unexpectedly reboots, log messages can be useful to diagnose the cause. However, log messages are
erased when the system reboots unless you enable persistent logging.
Caution! Enabling persistent logging can wear out the ash (non-volatile) memory and degrade
network performance. You should only enable persistent logging to debug a problem. Make sure
you disable persistent logging after you nish debugging the problem.
To congure persistent logging on the Events page, set the persistence, severity, and depth options as described in

volatile memory are deleted when the system reboots.
Severity Specify the severity level of the log messages to write to non-volatile memory. For example,
if you specify 2, critical, alert, and emergency logs are written to non-volatile memory. Error
messages with a severity level of 3 – 7 are written to volatile memory.
•) 0 — emergency
•) 1 — alert
•) 2 — critical
•) 3 — error
•) 4 — warning
•) 5 — notice
•) 6 — info
•) 7 — debug
Depth You can store up to 128 messages in non-volatile memory and 512 messages in volatile
memory. Once the number you congure in this eld is reached, the oldest log event is
overwritten by the new log event.

and restart system processes. If this happens, wireless clients will temporarily lose connectivity.
We recommend that you change AP settings when WLAN trafc is low.
Conguring 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 rst set up a remote
server running a syslog process and acting as a syslog log relay host on your network. Then, you can congure 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 congure a remote server to receive the syslog messages. The procedure to
congure 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 recongure the log port, make sure that the port number you assign to
syslog is not being used by another process.
Enabling or Disabling the Log Relay Host on the Events Page
To enable and congure Log Relaying on the Events page, set the Log Relay options as described in the following
table, and then click .Update
Field Description

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 means the client is associated with VAP 0 on Radio 1. An entry of wlan0 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 eld 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 trafc specication that is sent from a QoS-capable wireless client to an AP requesting a certain
amount of network access for the trafc stream (TS) it represents. A trafc stream is a collection of data packets
identied by the wireless client as belonging to a particular user priority. An example of a voice trafc stream is a Wi-Fi
CERTIFIED™ telephone handset that marks its codec-generated data packets as voice priority trafc. An example of
a video trafc stream is a video player application on a wireless laptop that prioritizes a video conference feed from a

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 trafc is passing. This allows the AP to detect
when a client goes out of range, even during periods when no normal trafc 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

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 congure 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 congured on your network with a different VLAN ID, you must change the VLAN ID of the
management VLAN on the AP.
Management IPv6 settings describe the IPv6 conguration of Management Interface. Use this page to congure the
IPv6 admin mode, IPv6 auto-cong admin mode, connection type (DHCPv6 or Static IPv6 addressing) and DNS

IPv6 Tunnel
The ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) provides the support for encapsulating IPv6 packets
within IPv4 packets to allow transmission over IPv4 networks. This feature provides AP to act as an initiator of the
tunnel and will allow communication with remote IPv6 hosts. An ISATAP router acts as the end of the tunnel within the
network to help AP to auto-congure ISATAP tunnel interface.

Field Description
Mode Mode The denes 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:
•) IEEE 802.11a is a PHY standard that species 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).
•) IEEE 802.11a/n/ac: All the 802.11a, 802.11n and 802.11ac clients operating in the 5
GHz frequency can connect to the AP.
•) IEEE 802.11n/ac: 802.11n clients and 802.11ac clients operating in the 5-GHz
frequency can connect to the AP.
Channel ChannelSelect the .
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 trafc is detected.
The Channel denes 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 eld. This allows the automatic channel feature to set
the channels for the radios in the cluster.
Station Isolation 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 trafc 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 trafc 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.

AeroScout™ Engine
Protocol Support
AeroScout Engine support provides location-based services for wireless networks. Specify
whether to enable support for the AeroScout protocol.
Options are or . The default is . When enabled, Aeroscout Enabled Disabled Disabled
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 congured 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 41.
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 Specication, version 2.1.
Note: AeroScout tags operate only in 802.11 b/g mode. Therefore, network administrators
who use the AeroScout tags must congure 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 congured 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.
Table 20 - Wireless Settings
Note: After you congure the wireless 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 trafc 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 difcult 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 “Conguring Load
Balancing” on page 64.
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 congured with the IP address of the managed access points from which it collects

Section 4 - Managing the Access Point
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
congure 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 congured in 2.4 GHz IEEE 802.11n mode 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.
Modifying Radio Settings
Radio settings directly control the behaviour of the radio devices in the AP and its interaction with the physical
medium; that is, how and what type of electromagnetic waves the AP emits.
To specify radio settings, click the tab in the section.Radio Manage
Different settings will be displayed depending on the mode you select. All settings are described in the table below.

(802.11b/g/n).
Status (On/Off) Specify whether you want the radio on or off by clicking or . On Off
If you turn off a radio, the AP sends disassociation frames to all the wireless clients it is
currently supporting so that the radio can be gracefully shutdown and the clients can start

Field Description
Primary Channel
(802.11n modes
only)
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 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:
•) Lower — Set the Primary Channel as the lower 20 MHz channel in the 40 MHz band.
•) Upper — Set the Primary Channel as the upper 20 MHz channel in the 40 MHz band.
DFS Support This eld is available only if the selected radio mode operates in the 5 GHz frequency.
For radios in the 5 GHz band, when DFS support is on and the regulatory domain requires
radar detection on the channel, the Dynamic Frequency Selection (DFS) and Transmit
Power Control (TPC) features of 802.11h are activated.
DFS is a mechanism that requires wireless devices to share spectrum and avoid co-channel
operation with radar systems in the 5 GHz band. DFS requirements vary based on the
regulatory domain, which is determined by the country code setting of the AP.
Short Guard Interval
Supported
This eld is available only if the selected radio mode includes 802.11n.
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 denition 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 400ns guard Interval when communicating with
clients that also support the short guard interval.
•) No — The AP transmits data using an 800ns guard interval.
Multidomain
Regulatory Mode
This feature is congurable on a per radio basis. By default, it is enabled. Multidomain
Regulatory Mode (World Mode) causes the AP to broadcast which country it is operating in
as a part of its beacons and probe responses. This allows client stations to operate in any
country without re-conguration.
Disabling this feature prevents the country code setting from being broadcast in the
beacons. However, this only applies to radios congured to operate in the g band (2.4 GHz
band). For radios operating in the a band (5 GHz band), the AP software congures support
for 802.11h. When 802.11h is supported, the country code information is broadcast in the
beacons.
To enable Multidomain Regulatory Mode support, click Enabled.
To disable Multidomain Regulatory Mode support, click Disabled.
STBC Mode This eld 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.
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 ( ). With protection enabled, protection mechanisms will be invoked if legacy Auto
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 ( ) these protection mechanisms; however, when 802.11n protection is Off
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 Interval Beacon frames are transmitted by an AP at regular intervals to announce the existence
of the wireless network. The default behaviour is to send a beacon frame once every 100
milliseconds (or 10 per second).
Enter a value from 20 to 2000 milliseconds.

Section 4 - Managing the Access Point
Field Description
DTIM Period Specify a DTIM period from 1 to 255 beacons.
The Delivery Trafc 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 eld to 1, clients will check
for buffered data on the AP at every beacon. If you set this eld to 10, clients will check on
every 10th beacon.
Fragmentation
Threshold
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 ( ) effectively fragmentation. 2,346 bytes disables
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 trafc on the network.
However, fragmentation can help improve network performance and reliability if properly
congured.
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 trafc ow 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-efcient 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.
Fixed Multicast Rate Select the multicast trafc transmission rate you want the AP to support.
Frame-burst
Support
Frame-burst Support boosts up the downstream throughput.
Legacy Rate Sets Check the transmission rate sets you want the AP to support and the basic rate sets you
want the AP to advertise:
•) 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 efcient 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 efcient to have an AP broadcast a subset of its
supported rate sets.

Conguring Radio and VAP Scheduler
The Radio and VAP scheduler is a standalone DWL-x600AP feature. To congure the Radio and VAP scheduler,
select the tab in the Scheduler Manage section. The Radio and VAP Scheduler allows you to congure a rule with a
specic 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 ofce 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 specic times of day.
Each rule species 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.

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 conguring VAPs, you can maintain better control over broadcast and multicast trafc, which affects network
performance.
You can congure each VAP to use a different VLAN, or you can congure 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 trafc based on the VLAN ID you congure on the VAP page or by using
the RADIUS server assignment. If you use an external RADIUS server, you can congure multiple VLANs on each
VAP. The external RADIUS server assigns wireless clients to the VLAN when the clients associate and authenticate.

Section 4 - Managing the Access Point
You can congure 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
congured RADIUS servers. You can congure each VAP to use the global RADIUS server settings, which is the
default, or you can congure a per-VAP RADIUS server set. You can also congure separate RADIUS server settings
for each VAP. For example, you can congure one VAP to use an IPv6 RADIUS server while other VAPs use the
global IPv4 RADIUS server settings you congure.
If wireless clients use a security mode that does not communicate with the RADIUS 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 congure 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.

Field Description
RADIUS IP Address
Type
Specify the IP version that the RADIUS server uses.
You can toggle between the address types to congure IPv4 IPv6 and global RADIUS
address settings, but the AP contacts only the RADIUS server or servers for the address
type you select in this eld.
RADIUS IP Address
RADIUS IPv6
Address
Enter the IPv4 or IPv6 address for the primary global RADIUS server. By default, each VAP
uses the global RADIUS settings that you dene for the AP at the top of the VAP page.
When the rst 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 eld, 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.

label is RADIUS IP Address when the IPv4 RADIUS IP Address Type option is selected and
RADIUS IPv6 Address when the IPv6 RADIUS IP Address Type option is selected.
If authentication fails with the primary server, each congured 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 is the shared secret key for the global RADIUS server. You can use up to RADIUS Key
63 standard alphanumeric and special characters. The key is case sensitive, and you must
congure 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.
RADIUS Key 1–3 Enter the RADIUS key associated with the congured 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.
Enable RADIUS
Accounting
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.

FailThrough
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.
Radio Select the radio to congure. VAPs are congured independently on each radio.
VAP You can congure up to 16 VAPs for each radio. VAP0 is the physical radio interface, so to
disable VAP0, you must disable the radio.
Enabled You can enable or disable a congured network.
•) To enable the specied network, select the Enabled option beside the appropriate
VAP.
•) To disable the specied network, clear the Enabled option beside the appropriate VAP.
If you disable the specied network, you will lose the VLAN ID you entered.
VLAN ID When a wireless client connects to the AP by using this VAP, the AP tags all trafc from the
wireless client with the VLAN ID you enter in this eld 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 le in the RADIUS or AAA server to congure a VLAN for the
client:
•) “Tunnel-Type”
•) “Tunnel-Medium-Type”
•) “Tunnel-Private-Group-ID”
The RADIUS-assigned VLAN ID overrides the VLAN ID you congure on the VAP page.
You congure the untagged and management VLAN IDs on the Ethernet Settings page. For
more information, see “Ethernet Settings” on page 36.
SSID 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.

Field Description
Broadcast SSID Specify whether to allow the AP to broadcast the Service Set Identier (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 congured in the
supplicant before it is able to connect.
•) To enable the SSID broadcast, select the check box. Broadcast SSID
•) To prohibit the SSID broadcast, clear the check box.Broadcast SSID
Note: Disabling the broadcast SSID is sufcient 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 trafc. 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.
Security Security Select one of the following modes for this VAP:
•) None
•) Static WEP
•) WPA Personal
•) IEEE 802.1X
•) WPA Enterprise
If you select a security mode other than None, additional elds appear. These elds are
explained below.
Note: The Security mode you set here is specically for this VAP.
MAC Authentication
Type
You can congure 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 congure on the MAC Authentication

Table 24 - Virtual Access Point Settings
Note: After you congure 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 trafc is low.
None (Plain-text)
If you select None as your security mode, no further options are congurable 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
conguration or for problem solving, but it is not recommended for regular use on the Internal network because it is
not secure.
Static WEP
Unied Access Point Administrator’s Guide
Unied Access Point Administrator’s Guide
Page 54
October 2017
Section 4 - Managing the Access Point
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. All wireless stations and
APs on the network are congured 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 snifng out unencrypted wireless trafc.
WEP encrypts data moving across the wireless network based on a static key. (The encryption algorithm is a stream
cipher called RC4.)
Figure 25 - Modify Virtual Access Point Settings (Static WEP)
Field Description
Transfer Key Index Select a key index from the drop-down menu. Key indexes 1 through 4 are available. The
default is 1.
The Transfer Key Index indicates which WEP key the AP will use to encrypt the data it
transmits.
Key Length Specify the length of the key by clicking one of the radio buttons:
•) 64 bits
•) 128 bits
Key Type Select the key type by clicking one of the radio buttons:
•) ASCII
•) Hex
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 specied in the Characters Required
eld. These are the RC4 WEP keys shared with the stations using the AP.
Each client station must be congured to use one of these same WEP keys in the same slot
as specied here on the AP.
Characters Required: The number of characters you enter into the WEP Key elds 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.

Section 4 - Managing the Access Point
Field Description
Authentication The authentication algorithm denes 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
trafc 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 congured to use WEP in shared key mode must have a valid WEP
key in order to associate with the AP.
•) Client stations congured 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.
Table 25 - Static WEP
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 specied 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 denes abc123
key as WEP key 3, then the client stations must dene 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 congure multiple WEP keys and dene 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 dening 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 certicates,
Kerberos, and public key authentication. You must congure the client stations to use the same authentication method
the AP uses.

WPA Personal
WPA Personal is a Wi-Fi Alliance IEEE 802.11i standard, which includes AES-CCMP and TKIP mechanisms. The
Personal version of WPA employs a pre-shared key (instead of using IEEE 802.1X and EAP as is used in the
Enterprise WPA security mode). The PSK is used for an initial check of credentials only.
This security mode is backwards-compatible for wireless clients that support the original WPA.
Figure 27 - Modify Virtual Access Point Settings (WPA Personal)
Field Description
WPA Versions Select the types of client stations you want to support:
•) WPA. If all client stations on the network support the original WPA but none support the
newer WPA2, then select WPA.
•) WPA2. If all client stations on the network support WPA2, we suggest using WPA2
which provides the best security per the IEEE 802.11i standard.
•) WPA and WPA2. If you have a mix of clients, some of which support WPA2 and others
which support only the original WPA, select both of the check boxes. This lets both
WPA and WPA2 client stations associate and authenticate, but uses the more robust

If for WPA Versions you select only WPA2 or both WPA and WPA2, you can enable pre-
authentication for WPA2 clients.
Click if you want WPA2 wireless clients to send pre-Enable pre-authentication
authentication packet. The pre-authentication information will be relayed from the AP
the client is currently using to the target AP. Enabling this feature can help speed up
authentication for roaming clients who connect to multiple APs.
This option does not apply if you selected WPA for WPA Versions because the original WPA
does not support this feature.
Cipher Suites Select the cipher suite you want to use:
•) TKIP
•) CCMP (AES)
•) TKIP CCMP (AES)and
By default both TKIP and CCMP are selected. When both TKIP and CCMP are selected,
client stations congured to use WPA with RADIUS must have one of the following:
•) A valid TKIP RADIUS IP address and RADIUS Key
•) A valid CCMP (AES) IP address and RADIUS Key

Table 29 - Wireless Multicast Forwarding
Conguring the Wireless Distribution System (WDS)
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 congure 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 trafc 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 conguration 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 congure the AP by using the D-Link Unied Wireless Switch. The
Administrator UI, as well as Telnet, SSH, and SNMP access are disabled when the AP is in
Managed Mode.

Before you congure WDS on the AP, note the following guidelines:
•) APs participating in the WDS link.When using WDS, be sure to congure WDS settings on both
•) 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 42 for information on conguring the Radio mode and
channel.)
•) When 802.11h is operational, setting up two WDS links can be difcult.
To congure WDS on this AP, describe each AP intended to receive handoffs and send information to this AP. For each
destination AP, congure the elds listed in the table below.
Field Description
Spanning Tree
Mode
Spanning Tree Protocol (STP) prevents switching loops. STP is recommended if you
congure WDS links.
Select to use STPEnabled
Select to turn off STP links (not recommended)Disabled
Radio For each WDS link on a two-radio AP, select Radio One or Radio Two. The rest of the
settings for the link apply to the radio selected in this eld. The read-only Local Address will
change depending on which Radio you select in this eld.
Local Address Indicates the MAC addresses for this AP.
For each WDS link on a two-radio AP, the Local Address reects the MAC address for the
internal interface on the selected radio (Radio One on wlan0 or Radio Two on wlan1).
Remote Address Specify the of the destination AP; that is, the AP on the other end of the WDS MAC address
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 eld 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.
Encryption You can use , , or no encryption WEP 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.

Section 4 - Managing the Access Point
Controlling Access by MAC Authentication
A Media Access Control (MAC) address is a hardware address that uniquely identies 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 congure a global list of MAC addresses locally on the AP or on an external RADIUS
server. Then, you set a lter 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 congured
locally on the MAC Authentication page or the external RADIUS server. The Allow/Block lter 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 50.
Conguring 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 lter, you can only client stations with a listed MAC address or allow 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 ltering by MAC address, click the MAC Authentication tab.
Figure 31 - Congure MAC Authentication
Note: Global MAC Authentication settings apply to all VAPs on all supported radios.
The following table describes the elds and conguration options available on the MAC Authentication page.

Section 4 - Managing the Access Point
Field Description
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 lter you select is applied to the clients in the station list, regardless of whether
that station list is local or on the RADIUS server.
Stations List 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 lter
in the previous eld.
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 congured in this list and uses the list that is
stored on the RADIUS server. The MAC authentication type is set on the VAP conguration
page.

Note: After you congure local MAC Authentication 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 trafc is low.
Conguring MAC Authentication on the RADIUS Server
If you use RADIUS MAC authentication for MAC-based access control, you must congure a station list on the
RADIUS server. The station list contains client MAC address entries, and the format for the list is described in the
following table.
RADIUS Server Attribute Description Value
User-Name (1) MAC address of the client station. Valid Ethernet MAC Address.
User-Password (2) A xed global password used to
lookup a client MAC entry.

Managed Access Point Overview
The UAP can operate in two modes: or Standalone Mode 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 Unied Wired and Wireless System, and you manage it by using
the D-Link Unied 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 congure the IP addresses of up to four D-Link Unied 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.
Transition Between Modes
Every 30 seconds, the D-Link Unied 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 trafc without any loss. The AP uses the
conguration on the VAPs congured 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, 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 conguration and the AP sends the wireless switch information about all currently
associated clients.
After the conguration from the switch is applied, the AP radio(s) restart. Client trafc is briey interrupted until the
radio(s) are up and the clients are re-associated.

Conguring SNMP on the Access Point
Simple Network Management Protocol (SNMP) denes 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 specically noted, all conguration 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 page under the Services heading, you can start or stop control of SNMP agents, congure community SNMP
passwords, access MIBs, and congure SNMP Trap destinations.

You can specify the SNMP administrative mode on your network. By default SNMP is
enabled. To enable SNMP, click . To disable SNMP, click Enabled Disabled. After changing
the mode, you must click Apply to save your conguration changes.
Note: If SNMP is disabled, all remaining elds on the SNMP page are disabled. This is a
global SNMP parameter which applies to SNMPv1, SNMPv2c, and SNMPv3.
Read-only
community name
(for permitted SNMP
get operations)
Enter a read-only community name. The valid range is 1-256 characters.
The community name, as dened in SNMPv2c, acts as a simple authentication mechanism
to restrict the machines on the network that can request data to the SNMP agent. The name
functions as a password, and the request is assumed to be authentic if the sender knows
the password.
The community name can be in any alphanumeric format.
Port number the
SNMP agent will
listen to
By default an SNMP agent only listens to requests from port 161. However, you can
congure this so the agent listens to requests on another port.
Enter the port number on which you want the SNMP agents to listen to requests. The valid
range is 1-65535.
Note: This is a global SNMP parameter that applies to SNMPv1, SNMPv2c, and SNMPv3.
Allow SNMP set
requests
You can choose whether or not to allow SNMP set requests on the AP. Enabling SNMP
set requests means that machines on the network can execute conguration changes via
the SNMP agent on the AP to the D-Link System MIB. To enable SNMP set requests, click
Enabled. To disable SNMP set requests, click Disabled.
Read-write
community name
(for permitted SNMP
set operations)
If you have enabled SNMP set requests you can set a read-write community name. The
valid range is 1-256 characters.
Setting a community name is similar to setting a password. Only requests from the
machines that identify themselves with this community name will be accepted.
The community name can be in any alphanumeric format.
Restrict the source
of SNMP requests to
only the designated
hosts or subnets
You can restrict the source of permitted SNMP requests.
To restrict the source of permitted SNMP requests, click Enabled.
To permit any source submitting an SNMP request, click Disabled.

Field Description
Hostname,
address or subnet
of Network
Management
System
Specify the IPv4 DNS hostname or subnet of the machines that can execute get and set
requests to the managed devices. The valid range is 1-256 characters.
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 specied here.
To specify a subnet, enter one or more subnetwork address ranges in the form address/
mask_length where is an IP address and is the number of mask bits. address mask_length
Both formats are supported. Individual hosts address/mask and address/mask_length
can be provided for this, i.e. IP Address or Hostname. For example, if you enter a range of
192.168.1.0/24 this species 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
identied by sufx .0 in a subnetwork range is always reserved for the subnet address, and
the address identied 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.
IPv6 Hostname
or IPv6 subnet
of Network
Management
System
Specify the IPv6 DNS hostname or subnet of the machines that can execute get and set
requests to the managed devices.
Community name
for traps
Enter the global community string associated with SNMP traps. The valid range is 1-256
characters.
Traps sent from the device will provide this string as a community name.
The community name can be in any alphanumeric format. Special characters are not
permitted.
Host Type Specify whether the enabled host is an IPv4 host or an IPv6 host.
Hostname or IP
address
Enter the DNS hostname of the computer to which you want to send SNMP traps. The valid
range is 1-256 characters.
An example of a DNS hostname is: snmptraps.foo.com. Since SNMP traps are sent
randomly from the SNMP agent, it makes sense to specify where exactly the traps should
be sent. You can add up to a maximum of three DNS hostnames. Ensure you select the
Enabled check box beside the appropriate hostname.

The value specied for Minimum Contention Window is the upper limit (in milliseconds) of a
range from which the initial random back off wait time is determined.
The rst random number generated will be a number between 0 and the number specied
here.
If the rst random back off wait time expires before the data frame is sent, a retry counter
is incremented and the random back off value (window) is doubled. Doubling will continue
until the size of the random back off value reaches the number dened 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 (Maximum
Contention Window)
The value specied for the Maximum Contention Window is the upper limit (in milliseconds)
for the doubling of the random back off value. This doubling continues until either the data
frame is sent or the Maximum Contention Window size is reached.
Once the Maximum Contention Window size is reached, retries will continue until a
maximum number of retries allowed is reached.
Valid values for cwMax are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for cwMax
must be higher than the value for cwMin.
Max. Burst Length Max. Burst Length The is an AP EDCA parameter and only applies to trafc owing from
the AP to the client station.
This value species (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.
Wi-Fi Multimedia (WMM) Settings
Wi-Fi MultiMedia
(WMM)
Wi-Fi MultiMedia (WMM) is enabled by default. With WMM enabled, QoS prioritization and
coordination of wireless medium access is on. With WMM enabled, QoS settings on the
UAP control downstream trafc owing from the AP to client station (AP EDCA parameters)
and the upstream trafc owing from the station to the AP (station EDCA parameters).
Disabling WMM deactivates QoS control of station EDCA parameters on trafc upstream
owing from the station to the AP.
With WMM disabled, you can still set some parameters on the trafc owing downstream
from the AP to the client station (AP EDCA parameters).
To disable WMM extensions, click Disabled.
To enable WMM extensions, click Enabled.
Station EDCA Parameters
Queue Queues are dened for different types of data transmitted from station-to-AP:
•) Data 0 (Voice) — Highest priority queue, minimum delay. Time-sensitive data such as
VoIP and streaming media are automatically sent to this queue.
•) Data 1(Video) — Highest 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).
AIFS (Inter-Frame
Space)
The Arbitration Inter-Frame Spacing (AIFS) species a wait time for data frames. The wait
time is measured in slots. Valid values for AIFS are 1 through 255.

Field Description
cwMin (Minimum
Contention Window)
This parameter is used by the algorithm that determines the initial random back off wait
time (window) for retry of a data transmission during a period of contention for Unied
Access Point resources. The value specied here in the Minimum Contention Window is
the upper limit (in milliseconds) of a range from which the initial random back off wait time
will be determined. The rst random number generated will be a number between 0 and the
number specied here. If the rst random back off wait time expires before the data frame
is sent, a retry counter is incremented and the random back off value (window) is doubled.
Doubling will continue until the size of the random back off value reaches the number
dened in the Maximum Contention Window.
cwMax (Maximum
Contention Window)
The value specied here in the Maximum Contention Window is the upper limit (in
milliseconds) for the doubling of the random back off value. This doubling continues until
either the data frame is sent or the Maximum Contention Window size is reached.
Once the Maximum Contention Window size is reached, retries will continue until a
maximum number of retries allowed is reached.
TXOP Limit The TXOP Limit is a station EDCA parameter and only applies to trafc owing from the
client station to the AP. The Transmission Opportunity (TXOP) is an interval of time, in
milliseconds, when a WME client station has the right to initiate transmissions onto the
wireless medium (WM) towards the Unied Access Point. The TXOP Limit maximum value is
65535.
Other QoS Settings
No
Acknowledgement
Select On to specify that the AP should not acknowledge frames with QosNoAck as the
service class value.
APSD Select On to enable Automatic Power Save Delivery (APSD), which is a power management
method. APSD is recommended if VoIP phones access the network through the AP.
Note: After you congure the QoS 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 trafc is low.

Enabling the Time Settings (NTP)
Use the page to specify the Network Time Protocol (NTP) server to use to provide time and date Time Settings
information to the AP or to congure 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 the
Services > Time Settings (NTP) tab and update the elds as described in the table below.

Conguring SNMPv3 Views
A MIB view is a 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 view subtree, create a corresponding entry with the excluded included
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 entry with the OID 1.3.6.1.4. excluded
Then, create an entry with OID .1 with the same view name. included
Figure 44 - SNMPv3 Views Conguration
The following table describes the elds you can congure on the SNMPv3 Views page.
Field Description
View Name Enter a name to identify the MIB view.
View names can contain up to 32 alphanumeric characters.
Type Species whether to the view subtree or family of subtrees from the MIB include exclude or
view.
OID OID string Enter an for the subtree to include or exclude from the view.
For example, the system subtree is specied by the OID string .1.3.6.1.2.1.1.
Mask OID mask The 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 eld. For example,
OID mask FA.80 is 11111010.10000000.
A family mask is used to dene a family of view subtrees. The family mask indicates which
sub-identiers of the associated family OID string are signicant to the family’s denition.
A family of view subtrees allows control access to one row in a table, in a more efcient
manner.
