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-2600AP and DWL-3600AP are single-radio access points and support the IEEE
802.11b, IEEE 802.11g, and 802.11n (2.4 GHz) modes. The DWL-3610AP is a single-radio access point that supports
both 2.4 GHz (IEEE 802.11b, 802.11g, 2.4 GHz IEEE 802.11n) and 5 GHz (IEEE 802.11a, 802.11n, 802.11ac) modes.
The DWL-6610, DWL-8610, and DWL-8710 are dual radio access points and support all the modes (IEEE 802.11a,
IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and IEEE 802.11ac)

•) “Verifying the Installation” on page 20
•) “Configuring Security on the Wireless Access Point” on page 21
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
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).

Required Software or Component
Description
Wireless Connection to the Network
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.
Web Browser and Operating System
Configuration and administration of the UAP is provided through a Webbased 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
configure 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 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.
Required Component

Section 2 - Getting Started
Required Component
Description
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 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 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 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 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.
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 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 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 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.
October 2016
Unified Access Point Administrator’s Guide
Page 13
Unified Access Point Administrator’s Guide
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 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).
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:
•) 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 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.
4.) When prompted, enter admin for the user name and admin for the password, then click Logon.

Figure 2 - Web UI Login Prompt
After you log in, the Basic Settings page for UAP administration is displayed, as the following figure shows.
Figure 3 - Provide Basic Settings
5.) Verify the settings on the Basic Settings page.
•) 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 Apply button to activate the wireless network with these new settings.
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 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 “Configuring the
Ethernet Settings” on page 18 (CLI) or “Ethernet Settings” on page 36 (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 18
(CLI) or “Ethernet Settings” on page 36 (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 19.

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 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-fe002420s6.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.
Figure 4 - Command Line Interface (CLI) Connection
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 page
36. You can also use the CLI to configure the Ethernet settings, which the following section describes.

Configuring IEEE 802.1X Authentication
On networks that use IEEE 802.1X, port-based network access control, a supplicant (client) cannot gain access to
the network until the 802.1X authenticator grants access. If your network uses 802.1X, you must configure 802.1X
authentication information that the AP can supply to the authenticator.
If your network uses IEEE 802.1X see “Configuring IEEE 802.1X Authentication” on page 19 for information about

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:
•) 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 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

Unified Access Point Administrator’s Guide
Page 20
Unified Access Point Administrator’s Guide
Section 2 - Getting Started
your LAN. An important next step is to configure security, as described in “Virtual Access Point Settings” on page
50.
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
50.

Viewing Events
The Events page shows real-time system events on the AP such as wireless clients associating with the AP and being
authenticated.
To view system events, click the Events tab.
Figure 6 - Viewing Events
From the Events page, you can perform the following tasks:
•) View the most recent, high-level events generated by this AP.
•) Enable and configure Persistent logging to write system event logs to non-volatile memory so that the events
are not erased when the system reboots.
•) 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.
Configuring 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 flash (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 finish debugging the problem.
To configure persistent logging on the Events page, set the persistence, severity, and depth options as described in
the following table, and then click Apply.

Field
Description
Persistence
Choose Enabled to save system logs to non-volatile memory so that the logs are not erased
when the AP reboots. Choose Disabled to save system logs to volatile memory. Logs 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 configure in this field is reached, the oldest log event is
overwritten by the new log event.

Note: To apply your changes, click Apply. 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.
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.
Enabling or Disabling the Log Relay Host on the Events Page
To enable and configure Log Relaying on the Events page, set the Log Relay options as described in the following
table, and then click Update.
Field
Description
Relay Log
Select Enabled to allow the UAP to send log messages to a remote host. Select Disabled
to keep all log messages on the local system.

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

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

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.
Management IPv6 settings describe the IPv6 configuration of Management Interface. Use this page to configure the
IPv6 admin mode, IPv6 auto-config admin mode, connection type (DHCPv6 or Static IPv6 addressing) and DNS
servers. By default, the DHCPv6 client on the UAP automatically broadcasts requests for network information. If
you want to use a static IPv6 address, you must disable the DHCPv6 client and manually configure the Static IPv6
address and other network information.
To configure the LAN settings, click the Ethernet Settings tab.

Description
Mode
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:
•) 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).
•) 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
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.
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 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.

Description
AeroScout™ Engine AeroScout Engine support provides location-based services for wireless networks. Specify
Protocol Support
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 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 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.
Table 20 - Wireless Settings
Note: After you configure 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 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 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 configured 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
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 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 Radio tab in the Manage section.
Different settings will be displayed depending on the mode you select. All settings are described in the table below.

Status (On/Off)
Specify whether you want the radio on or off by clicking On or Off.
If you turn off a radio, the AP sends disassociation frames to all the wireless clients it is

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 field 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 This field is available only if the selected radio mode includes 802.11n.
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 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 configurable 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-configuration.
Disabling this feature prevents the country code setting from being broadcast in the
beacons. However, this only applies to radios configured to operate in the g band (2.4 GHz
band). For radios operating in the a band (5 GHz band), the AP software configures 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 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.

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 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 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.
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 (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.
Fixed Multicast Rate Select the multicast traffic 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 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.

Broadcast/Multicast
Rate Limiting
Enabling multicast and broadcast rate limiting can improve overall network performance by
limiting the number of packets transmitted across the network.
By default the Multicast/Broadcast Rate Limiting option is disabled. Until you enable
Multicast/Broadcast Rate Limiting, the following fields will be disabled:
•) Rate Limit - Enter the rate limit you want to set for multicast and broadcast traffic. The
limit should be greater than 1, but less than 50 packets per second. Any traffic that
falls below this rate limit will always conform and be transmitted to the appropriate
destination. The default and maximum rate limit setting is 50 packets per second.
•) Rate Limit Burst - Setting a rate limit burst determines how much traffic bursts can
be before all traffic exceeds the rate limit. This burst limit allows intermittent bursts of
traffic on a network above the set rate limit. The default and maximum rate limit burst
setting is 75 packets per second.
DHCP Offer/ACK to
Unicast
Enabling this feature will convert BOOTP replies from DHCP server to Unicast and send to
the requesting wireless client.
Multicast to Unicast
Enabling this feature will convert all multicast data stream to unicast stream and send to the
associated wireless clients.
Forced Roaming
Enabling this feature will detect and disconnect wireless clients based on the client RSSI. If
the client RSSI falls below the roaming threshold value, the client will be disassociated.
Further association attempts will be monitored and disconnected 3 times if its RSSI is below
the threshold value. If still the client tries association 4th time, the association will be logged
and allowed to connect.
TSPEC Mode
Regulates the overall TSPEC mode on the AP. The options are:
•) On — The AP handles TSPEC requests according to the TSPEC settings you
configure on the Radio page. Use this setting if the AP handles traffic from QoScapable devices, such as a Wi-Fi CERTIFIED phone.
•) Off — The AP ignores TSPEC requests from client stations. Use this setting if you do
not want to use TSPEC to give QoS-capable devices priority for time-sensitive traffic.
TSPEC Voice ACM
Mode
Regulates mandatory admission control (ACM) for the voice access category. The options
are:
•) On — A station is required to send a TSPEC request for bandwidth to the AP before
sending or receiving a voice traffic stream. The AP responds with the result of the
request, which includes the allotted medium time if the TSPEC was admitted.
•) Off — A station can send and receive voice priority traffic without requiring an admitted
TSPEC; the AP ignores voice TSPEC requests from client stations.
TSPEC Voice ACM
Limit
Specify an upper limit on the amount of traffic the AP attempts to transmit on the wireless
medium using a voice AC to gain access.
TSPEC Video ACM
Mode
Regulates mandatory admission control for the video access category. The options are:
•) On — A station is required to send a TSPEC request for bandwidth to the AP before
sending or receiving a video traffic stream. The AP responds with the result of the

The purpose of this is to set Olpc Calibration Period which triggers a periodic calibration to
maintain output power same as target power for low power channels. The range of Olpc
Calibration Period is 10 to 20 minutes and ‘0’ is to disable the periodic calibration. This is
supported on 43431, 43460, and 43520 Radios.
Airtime Fairness
The purpose of this is to enable/disable Airtime Fairness. This feature addresses the issue
of slower data transfers throttling the higher speed ones.
Table 21 - Radio Settings
Note: It is recommended not to require Admission Control for the access categories BE (Best
Effort) and BK (Background). 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.

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.
October 2016
Unified Access Point Administrator’s Guide

Section 4 - Managing the Access Point
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.

Scheduler Association Settings
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.

Virtual Access Point Settings
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.

Section 4 - Managing the Access Point
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 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 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
Type
Specify the IP version that the RADIUS server uses.
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.
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 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.
RADIUS Key 1–3
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.
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.
If you enable RADIUS accounting, it is enabled for the primary RADIUS server and all
backup servers.
Enable RADIUS
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 configure. VAPs are configured independently on each radio.
VAP
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.
Enabled
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.
VLAN ID
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 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.

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.
Security
Select one of the following Security modes for this VAP:
•) None
•) Static WEP
•) WPA Personal
•) IEEE 802.1X

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
October 2016
Unified Access Point Administrator’s Guide
Page 53
Unified Access Point Administrator’s Guide
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 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.)
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

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 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.

Description
Authentication
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
Table 25 - Static WEP
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.

Use Global RADIUS
Server Settings
By default each VAP uses the global RADIUS settings that you define for the AP at the top
of the VAP page. However, you can configure each VAP to use a different set of RADIUS
servers.
To use the global RADIUS server settings, make sure the check box is selected.
To use a separate RADIUS server for the VAP, clear the check box and enter the RADIUS
server IP address and key in the following fields.
RADIUS IP Address
Type
Specify the IP version that the RADIUS server uses.
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
RADIUS IPv6
Address
Enter the IPv4 or IPv6 address for the primary RADIUS server for this VAP.
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
Address 1–3
Enter up to three IPv4 and/or IPv6 addresses to use as the backup RADIUS servers for this
VAP. The field 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 configured backup server is tried in
sequence.
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.
RADIUS Key 1 – 3
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.
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.
If you enable RADIUS accounting, it is enabled for the primary RADIUS server and all
backup servers.

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.

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
WPA2 for clients who support it. This WPA configuration allows more inter-operability,
at the expense of some security.
Cipher Suites
Select the cipher suite you want to use:
•) TKIP
•) CCMP (AES)
•) TKIP and CCMP (AES)
Both TKIP and AES clients can associate with the AP. WPA clients must have one of the
following to be able to associate with the AP:
•) A valid TKIP key
•) A valid AES-CCMP key
Clients not configured to use a WPA Personal will not be able to associate with the AP.
Key
The Pre-shared Key is the shared secret key for WPA Personal. Enter a string of at least 8
characters to a maximum of 63 characters. Acceptable characters include upper and lower
case alphabetic letters, the numeric digits, and special symbols such as @ and #.
Broadcast Key
Refresh Rate
Enter a value to set the interval at which the broadcast (group) key is refreshed for clients
associated to this VAP (the default is 300).
The valid range is 0–86400 seconds. A value of 0 indicates that the broadcast key is not
refreshed.

expense of some security.
Enable preauthentication
If for WPA Versions you select only WPA2 or both WPA and WPA2, you can enable preauthentication for WPA2 clients.
Click Enable pre-authentication if you want WPA2 wireless clients to send preauthentication 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 and CCMP (AES)
By default both TKIP and CCMP are selected. When both TKIP and CCMP are selected,
client stations configured 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

Configuring Wireless Multicast Forwarding
The Wireless Multicast Forwarding provides an efficient way to forward the multicast traffic on the wireless medium
and overcomes the multicast transmission issues on WLAN using the repeated unicast of multicast frames. It
uses IGMP frames to keep track of participating group members, and multicast packets are transmitted only to the
interested members after unicast MAC conversion .
With WMF, the data transfer is more reliable as the frames are sent as unicast, and robust transmission is possible
as dynamic per station rate control can be done based on the link errors and noise conditions. The multicast group
members can be a STA end point. Streaming between STA devices will also be supported. The multicast streaming
server can be attached to any of the LAN ports.

Configuring 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 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.

Figure 30 - Configure WDS Bridges
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 42 for information on configuring the Radio mode and
channel.)
•) When 802.11h is operational, setting up two WDS links can be difficult.
To configure WDS on this AP, describe each AP intended to receive handoffs and send information to this AP. For each
destination AP, configure the fields listed in the table below.

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 field. The read-only Local Address will
change depending on which Radio you select in this field.
Local Address
Indicates the MAC addresses for this AP.
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).
Remote Address
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.
Encryption
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.

Section 4 - Managing the Access Point
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 50.
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.
Figure 31 - Configure MAC Authentication
Note: Global MAC Authentication settings apply to all VAPs on all supported radios.
The following table describes the fields and configuration options available on the MAC Authentication page.

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.
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 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
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.
Transition 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, 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.

Description
SNMP Enabled/
Disabled
You can specify the SNMP administrative mode on your network. By default SNMP is
enabled. To enable SNMP, click Enabled. To disable SNMP, click Disabled. After changing
the mode, you must click Apply to save your configuration changes.
Note: If SNMP is disabled, all remaining fields 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 defined 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
configure 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 configuration 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.

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 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. IP 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.
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.

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, DWL-8600AP, DWL-6610AP, DWL-8610AP, and DWL-8710AP

cwMin (Minimum
This parameter is input to the algorithm that determines the initial random back off wait time
Contention Window) (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 back off wait time is determined.
The first random number generated will be a number between 0 and the number specified
here.
If the first 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 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 (Maximum
The value specified for the Maximum Contention Window is the upper limit (in milliseconds)
Contention Window) 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
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.
Wi-Fi Multimedia (WMM) Settings
Wi-Fi MultiMedia

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 the
Services > Time Settings (NTP) tab and update the fields as described in the table below.

Section 6 - Configuring SNMPv3
This section describes how to configure the SNMPv3 settings on the UAP and contains the following subsections:
•) “Configuring SNMPv3 Views” on page 80
•) “Configuring SNMPv3 Groups” on page 81
•) “Configuring SNMPv3 Users” on page 82
•) “Configuring SNMPv3 Targets” on page 83
Configuring 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 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.
Figure 44 - SNMPv3 Views Configuration
The following table describes the fields you can configure 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
Specifies whether to include or exclude the view subtree or family of subtrees from the MIB
view.
OID
Enter an OID string for the subtree to include or exclude from the view.
For example, the system subtree is specified by the OID string .1.3.6.1.2.1.1.
Mask
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.
SNMPv3 Views
This field shows the MIB views on the UAP. To remove a view, select it and click Remove.

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 the table below
describes.
Figure 45 - SNMPv3 Groups Configuration
Field
Description
Name
Specify a name to use to identify the group. The default group names are RW and RO.
Group names can contain up to 32 alphanumeric characters.
Security Level
Select one of the following security levels for the group:
•) noAuthentication-noPrivacy — No authentication and no data encryption (no
security).
•) Authentication-noPrivacy — Authentication, but no data encryption. With this security
level, users send SNMP messages that use an MD5 key/password for authentication,
but not a DES key/password for encryption.
•) Authentication-Privacy — Authentication and data encryption. With this security level,
users send an MD5 key/password for authentication and a DES key/password for
encryption.
For groups that require authentication, encryption, or both, you must define the MD5 and
DES key/passwords on the SNMPv3 Users page.
Write Views
Select the write access to management objects (MIBs) for the group:
•) write-all — The group can create, alter, and delete MIBs.
•) write-none — The group is not allowed to create, alter, or delete MIBS.

Page 86
Unified Access Point Administrator’s Guide
Section 7 - Maintaining the Access Point
As new versions of the UAP firmware become available, you can upgrade the firmware on your devices to take
advantage of new features and enhancements. The AP uses a TFTP client for firmware upgrades. You can also use
HTTP to perform firmware upgrades.
After you upload new firmware and the system reboots, the newly added firmware becomes the primary image. If the
upgrade fails, the original firmware remains as the primary image.
Note: When you upgrade the firmware, the access point retains the existing configuration
information.
Use the following steps to upgrade the firmware on an access point by using TFTP:
1.) Select TFTP for Upload Method.
Figure 55 - Manage Firmware (TFTP)
2.) Enter a name (1 to 255 characters) for the image file in the Image Filename field, including the path to the
directory that contains the image to upload.
For example, to upload the ap_upgrade.tar image located in the /share/builds/ap directory, enter /
share/builds/ap/ap_upgrade.tar in the Image Filename field.
The firmware upgrade file supplied must be a tar file. Do not attempt to use bin files or files of other formats for
the upgrade; these types of files will not work.
3.) Enter the Server IP address of the TFTP server.
4.) Click Upgrade.
Upon clicking Upgrade for the firmware upgrade, a popup confirmation window is displayed that describes the

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.

In promiscuous mode the radio receives all traffic on the channel, including traffic that is not
destined to this AP. While the radio is operating in promiscuous mode, it continues serving
associated clients. Packets not destined to the AP are not forwarded.
As soon as the capture is completed, the radio reverts to non-promiscuous mode operation.
Client Filter Enable
Enable to use the WLAN client filter to capture only frames that are transmitted to, or
received from a WLAN client with a specified MAC address.
Client Filter MAC

Max Capture File
Size
Specify the maximum allowed size for the capture file in KB (range 64 to 4096).
Table 53 - Packet File Capture
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.
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.
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.

Section 8 - Configuring Client Quality of Service (QoS)
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” on page 93
•) “Managing Client QoS ACLs” on page 94
•) “Creating a DiffServ Class Map” on page 100
•) “Creating a DiffServ Policy Map” on page 105
•) “Configuring RADIUS-Assigned Client QoS Parameters” on page 107
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 microflow 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.

Table 57 - VAP QoS Parameters
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.

Section 8 - Configuring Client Quality of Service (QoS)
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.
To configure an ACL, click the Client QoS ACL tab.
The fields to configure ACL rules appear only after you have created an ACL. The following image shows the
configuration of a new rule for the IPv4 ACL named acl1. The rule prevents HTTP traffic from all clients in the

IPv4 and IPv6 ACLs control access to network resources based on Layer 3 and Layer 4
criteria. MAC ACLs control access based on Layer 2 criteria.
ACL Rule Configuration
ACL Name - ACL
Type
Select the ACL to configure with the new rule. The list contains all ACLs added in the ACL
Configuration section.
Rule
To configure a new rule to add to the selected ACL, select New Rule. To add an existing rule
to an ACL or to modify a rule, select the rule number.
When an ACL has multiple rules, the rules are applied to the packet or frame in the order in
which you add them to the ACL. There is an implicit deny all rule as the final rule.
Action
Specifies whether the ACL rule permits or denies an action.
•) When you select Permit, the rule allows all traffic that meets the rule criteria to enter or
exit the AP (depending on the ACL direction you select). Traffic that does not meet the
criteria is dropped.
•) 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.
Match Every
Indicates that the rule, which either has a permit or deny action, will match the frame or
packet regardless of its contents.
If you select this field, you cannot configure any additional match criteria. The Match Every
option is selected by default for a new rule. You must clear the option to configure other
match fields.

Match to Value
To match a protocol that is not listed by name, enter the protocol ID.
The protocol ID is a standard value assigned by the IANA. The range is a number from
0–255.
Source IP Address
Select this field to require a packet’s source IP address to match the address listed here.
Enter an IP address in the appropriate field to apply this criteria.
Wild Card Mask
Specifies the source IP address wildcard mask.
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
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 behaviours.
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.

Section 8 - Configuring Client Quality of Service (QoS)
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

Creating a DiffServ Policy Map
Use the Policy Map page to create DiffServ policies and to associate a collection of classes with one or more policy
statements.
The UAP supports up to 50 Policy Maps.
Packets are classified and processed based on defined criteria. The classification criteria is defined by a class on the
Class Map page. The processing is defined by a policy’s attributes on the Policy Map page. 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 Map
can contain up to 10 Class Maps. 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.
To create a DiffServ policy, click the Policy Map tab.

Section 9 - 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.
This section describes the following features:
•) “Managing Cluster Access Points in the Cluster” on page 109
•) “Managing Cluster Sessions” on page 113
•) “Configuring and Viewing Channel Management Settings” on page 114
•) “Viewing Wireless Neighbourhood Information” on page 116
•) “Cluster Firmware Upgrade” on page 119
Managing Cluster 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 8 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 are identical models.
•) 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: DWL-6700AP doesn’t support clustering.
Clustering APs
Only identical models may be clustered together. For example, the DWL-2600AP can only form a cluster with other
DWL-2600APs.
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.
The following figure shows the Cluster > Access Points page when clustering is not enabled.

of the cluster in section. It has to be statically configured by the Cluster Administrator. The
Cluster IP management address should be part of the same subnet as the clustered AP
management IP addresses. The Cluster IP address is configured as secondary IP address
to the management interface of the Dominant AP. The Dominant AP user interface is
accessible using the Cluster IP address. When the Cluster IP address is set as secondary
IP address on the Dominant AP, it sends Gratuitous ARPs on the management VLAN so that
the mapping between the new IP address and the Mac-address is established in the subnet.

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
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.
Figure 71 - Manage Sessions Associated With The Cluster
Details about the session information shown is described in the following table.
Field
Description
AP Location
Indicates the location of the access point.
This is derived from the location description specified on the Basic Settings page.
User MAC
Indicates the MAC address of the wireless client device.
A MAC address is a hardware address that uniquely identifies each node of a network.
Idle
Indicates the amount of time this station has remained inactive.
A station is considered to be idle when it is not receiving or transmitting data.
Rate
The speed at which this access point is transferring data to the specified client.
The data transmission rate is measured in megabits per second (Mbps).
This value should fall within the range of the advertised rate set for the mode in use on the
access point. For example, 6 to 54 Mbps for 802.11a.
Signal

details, please refer to the following sections: “Cluster Options” on page 111, “Single IP Management” on page 111,
and “Secure Join Clustering” on page 111.
Note: Currently, Clustering Options, Single IP Management, and Secure Join Clustering features
are available only in DWL-3610AP and DWL-6610B1AP.
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.
Figure 72 - Automatically Manage Channel Assignments
From this page, you can view channel assignments for all APs in the cluster and stop or start automatic channel
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.

Section 9 - Clustering Multiple APs
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.
The following table provides details about Current Channel Assignments.
Field
Description
IP Address
Specifies the IP Address for the access point.
Radio
Identifies the MAC address of the radio.
Band
Indicates the band on which the access point is broadcasting.
Current
Indicates the radio Channel on which this access point is currently broadcasting.
Status
Shows whether the radio is up (on) or down (off).
Locked
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.
Table 68 - Channel Assignments
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.
Field
Description
IP Address
Specifies the IP Address for the access point.
Radio
Indicates the radio channel on which this access point is currently broadcasting.
Proposed Channel
Indicates the radio channel to which this access point would be re-assigned if the Channel
Plan is executed.

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 no fields
showing in the Advanced section, click the toggle button to display the settings that modify timing and details of the
channel planning algorithm.

Use the drop-down menu to choose percentages ranging from 5 percent to 75 percent.
This setting lets you set a gating factor for channel re-assignment so that the network is not
continually disrupted for minimal gains in efficiency.
For example, if channel interference must be reduced by 75 percent and the proposed
channel assignments will only reduce interference by 30 percent, then channels will not be
re-assigned. However; if you re-set the minimal channel interference benefit to 25 percent
and click Apply, the proposed channel plan will be implemented and channels re-assigned
as needed.

Field
Description
Neighbours
Access points which are neighbours of one or more of the clustered APs are listed in the left
column by SSID (Network Name).
An access point which is detected as a neighbour of a cluster member can also be a cluster
member itself. Neighbours who are also cluster members are always shown at the top of the
list with a heavy bar above and include a location indicator.
The coloured bars to the right of each AP in the Neighbours list shows the signal strength for
each of the neighbour 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 Neighbour 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 Neighbour seen by
the AP whose IP address is listed above that column
•) White Bar — A white bar and the number 0 indicates that a neighbouring 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
Neighbour 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).

Appendix B - Configuration Examples
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 behaviour 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.
