Wireless clients can roam among the access points managed by peer switches without losing network connections. Whether or not you have a peer group, the D-Link Unified Access System can support a total of 8000 wireless clients. D-Link WLAN Controller Switch The D-Link WLAN Controller Switch (WCS) handles Layer 2, 3, and 4 switching and routing functions for traffic on the wired and wireless LAN and manages up to 48 access points (APs).
DWS-3026 (24 GE ports + 2 10G ports) D-Link Access Point The D-Link Access Point is part of the D-Link Unified Access System, and you manage it by using the D-Link WLAN Controller Switch. By using the WCS to manage the access points, you can centralize AP management and streamline the AP upgrade process by pushing configuration profiles and software upgrades from the WCS to the managed APs.
1 Overview of the D-Link Unified Access System Figure 1 shows an example of a floor plan and network with a D-Link WLAN Controller Switch that manages two APs. The graph also shows a peer switch and a rogue AP in the network.
Management is standards-based, with configuration parameters and a private MIB that provides control for functions not completely specified in the standard MIBs. The method you use to configure and monitor the D-Link WLAN Controller Switch depends on your network size and requirements, and on your preference.

WLAN Topology Considerations The D-Link WLAN Controller Switch adds WLAN functionality to the base switching and IP routing features standard in most Layer 2/3 switches. Where you put the D-Link WLAN Controller Switch in your network depends on the size, requirements, and existing topology of your network.
8, the D-Link WLAN Controller Switches are both LAN and WLAN switches that handle traffic from end users connected to the wired LAN as well as traffic from the D-Link Access Points. In the diagram, Building 1 and Building 2 have a D-Link WLAN Controller Switch on each floor.
57. Access Point Placement D-Link Access Points can be on the same subnet as the switch or on a different subnet. You can connect the AP directly to the WCS or to another networking device. The range of the D-Link Access Point is about 100 meters, but the range is affected by various environmental factors.
APs in three different subnets. A D-Link WLAN Controller Switch controls the three APs. When the wireless client connects to any of the APs, it receives an IP address from the WCS that is in the L3 Tunnel subnet.

Configuring Access Point Settings After you validate a D-Link Access Point that associates with a switch, the switch assumes management functions for the AP. You can configure all of the AP settings directly from the switch before or after you validate the AP. This chapter describes the AP settings and how to manage them by using the D-Link WLAN Controller Switch.
In general, a wireless client connects to an access point by choosing a network (identified by the SSID) from a list of available wireless networks. You configure these wireless networks, including their associated SSID, on the D-Link WLAN Controller Switch. You manage the networks available on the WLAN by modifying or adding network configurations, which include settings for the SSID, VLAN ID, security, and tunneling parameters.
You can also manually set the channel and RF signal transmit power level for an individual AP, which overrides the channel and power settings in the AP profile. Configuring AAA and RADIUS Settings In the D-Link Unified Access System, you can use a RADIUS server for the following functions: •...

5 Configuring Access Point Settings Table 16. Valid AP Configuration Field Description Channel Channel defines the portion of the radio spectrum that the radio uses for transmitting and receiving. The range of channels and the default channel are determined by the Mode of the radio interface and the country in which the APs operate.
CLI, see the D-Link CLI Command Reference. Resetting the Access Points You can manually reset one or all APs from the D-Link WLAN Controller Switch. When you issue the command to reset an AP, the AP closes the SSL connection to the switch before resetting the hardware.
Configuring Channel Plan and Power Settings The D-Link WLAN Controller Switch software contains a channel plan algorithm that automatically determines which RF channels each D-Link Access Point should use to minimize RF interference. When you enable the channel plan algorithm, the switch periodically evaluates the operational channel on every AP it manages and changes the channel if the current channel is noisy.
6 Managing and Maintaining D-Link Access Points Additionally, radios configured to use Super A or Super G cannot use the channel plan algorithm. The RF transmission power level affects how far an AP broadcasts its signal. If the power level is too low, wireless clients will not detect the signal or experience poor WLAN performance.

The following example shows an INCLUDE etc/raddb/dictionary statement for the D-Link attribute dictionary called dictionary.D-Link $INCLUDE dictionary.D-Link Adding Access Points to the Valid AP Database You use the attributes you define in the dictionary file to configure the settings for an access point in the Valid AP database on the RADIUS server.
D-Link Unified Access System User Manual Configuring RADIUS Settings for Wireless Clients You can configure D-Link Access Points to use 802.1x authentication on the RADIUS server to allow or deny specific users on client stations access to the wireless network. If you enable 802.1x authentication, the client entry on a RADIUS server can support user-based VLANs...
Configuring the External RADIUS Server Configuring User-Based Authentication and Dynamic VLANs You can configure an entry in the external RADIUS server to pass a users credentials to the access point and to dynamically assign the user to a VLAN. Dynamic VLANs allow you to assign a user to a VLAN, and switches dynamically use this information to configure the port on the switch automatically.
L3 Roaming Example The example in this appendix describes how to configure a D-Link WLAN Controller Switch for a network that needs L3 roaming capabilities. This example contains information about the following features, which might be required to use L3 tunneling on your WLAN: •...
5. Enter an IPv4 address and subnet mask in the appropriate fields, and then click Submit. Creating the VLAN Routing Interface The D-Link WLAN Controller Switch and the D-Link Access Point support Virtual LANs (VLANs) to provide the logical separation of a physical network. You can use VLANs to segment the wireless network on a per-VAP basis.
Page 191
L3 Roaming Example 1. From the L2 Features > VLAN > Configuration page, create a VLAN, give it a name, and add the port to which the call server is attached to VLAN 200 (in this example, the call server is attached to port 3). 2.
L3 Roaming Example Example of Configuring L3 Roaming by Using the CLI The following procedures show how to configure the D-Link WLAN Controller Switch by using the CLI. The Web interface configuration procedures follow this example. 1. Enter the network configuration mode for network 3.

Admin Mode, then click Submit. Configuring the DHCP Server To configure DHCP on the D-Link WLAN Controller Switch, you configure the global DHCP settings and the address pool for the clients. The following example shows how to create an address pool for the wireless clients on the L3 Tunnel network.
Page 199
L3 Roaming Example Use the following procedures to perform the same configuration by using the Web interface. 1. From the Administration > DHCP Server > Global Configuration page, enable the Admin Mode and enter the range of IP addresses that you do not want to assign to wireless clients, then click Submit.
The MTU determines the maximum size of a packet that can be transmitted through a port in one frame. The default MTU size for the ports on the D-Link WLAN Controller Switch is 1518 bytes. Packets that use the L3 tunnel have an extra 20 bytes in the header for encapsulation.

L3 Roaming Example 3. Enter the MTU size in the Maximum Frame Size field. 4. Click Submit to apply your changes to the running configuration. 5. To make your changes permanent across a reboot, click Save Changes from the Tool Menu, t.
Voice-over-IP (VoIP), other types of audio, video, and streaming media as well as traditional IP data over the D-Link Unified Access System. A primary factor that affects QoS is network congestion due to an increased number of clients attempting to access the air waves and higher traffic volume competing for bandwidth during a busy time of day.
WMM-enabled by the Wi-Fi Alliance. Coordinating Traffic Flow Configuring QoS options on the D-Link Unified Access System consists of setting parameters on existing queues for different types of wireless traffic. You can configure different minimum and maximum wait times for the transmission of packets in each queue based on the requirements of the media being sent.
• Downstream from network to access point With WMM enabled, QoS settings on the D-Link Unified Access System affect the first two of these; downstream traffic flowing from the access point to client station (AP EDCA parameters) and the upstream traffic flowing from the station to the access point (station EDCA parameters).
Maximum Contention Window size is reached. Packet Bursting for Better Performance The D-Link Unified Access System includes 802.11e based packet bursting technology that increases data throughput and speed of transmission over the wireless network. Packet bursting enables the transmission of multiple packets without the extra overhead of header information.
Understanding Quality of Service TXOP Interval for Client Stations The Transmission Opportunity (TXOP) is an interval of time when a Wi-Fi Multimedia (WMM) client station has the right to initiate transmissions onto the wireless medium (WM). 802.1p and DSCP tags IEEE 802.1p is an extension of the IEEE 802 standard and is responsible for QoS provision.
