hello everyone. i am here searching for the steps or information to configure WLAN Controller for Lightweight Access Points. anyone have any review or have any idea how to do this?

When dealing with wireless (RF) networks, use these proven techniques. When deploying a wireless network, always perform the appropriate analysis units to ensure quality of service for wireless customers. Requirements for the deployment of services, voice or location of more stringent than those for data services. Auto-RF can be used for configuration management channel and power, but it can not correct a wrong structure of RF.

Analysis of the nodes must be performed using the device, the operation mode is appropriate for ensuring power and radio equipment to be used in the existing network. For example, do not use radio 350 802.11B with omni-directional antenna for the study area of coverage, if the final network uses dual radio 1240 for 802.11A and G. Using the same idea, limit the number of Service Set Identifier (SSID), configured on the controller. On model access point can be configured 8 or 16 simultaneous SSID, but because each WLAN / SSID needed some test answers and alarm, the amount of RF noise increases as you add SSID. As a result, some smaller wireless stations like PDA, WiFi-phones and devices bar code reader can not handle the large amount of baseline data SSID (BSSID). This in turn leads to rise block, reboots or failures when connecting. The greater the number of SSID, the greater the need alarm, the less space remains available for RF transmission of actual data.

In environments with large RF-free spaces, such as factories, where access points are separated and are not screened walls may need to change the threshold of the radiation power, the default and is equal to -65 dBm, the a lower value, eg -76 dBm. This helps to reduce noise during data transfer between the channels (the number of BSSID, "heard" of wireless customers at a time). The optimal value depends on environmental characteristics of each node, so the value should be assessed after analysis of nodes.

The threshold value of output power - is expressed in dBm limit the signal level relative to which the algorithm output power control (TPC) adjusts the power levels in descending order so that it was the importance of power in which "hear" a third of the power module is located next to the AP.

Necessary to limit the number of access points for each network VLAN. Recommended amount: from 30 to 60 (depending on characteristics of the network). This constraint is used to minimize problems with the re-connection failure in the network. As to the first board, it is not recommended to ask for more than 20 access points in one VLAN using management interface controller. Perhaps because of the large number of broadcast messages generated access points, some messages about finding discarded. This leads to a slower association points of access.

It is important to support roaming. If not all the controllers in the mobility group, use a virtual interface that can give the impression that roaming between controllers are stable, but control transfer is not completed and the client for a while lose the connection.

It is recommended to set the timeout for RADIUS protocol value of 5 seconds. The default value of 2 seconds is acceptable for fast failover RADIUS, but may be insufficient for an extended authentication at the transport layer network (EAP-TLS) or if the RADIUS server must be connected to external databases data.
