Overview
The AP configuration module allows you to perform the following configurations:
l Establish a CAPWAP connection
l Configure auto AP
l Configure AP group
Introduction to CAPWAP
Control And Provisioning of Wireless Access Points (CAPWAP) defines how an AP communicates with an AC. It provides a generic encapsulation and transport mechanism between AP and AC, as shown in Figure 1-1.
CAPWAP runs on an AP and an AC to provide a secured connection in between. It is built on a standard client/server model and employs UDP.
On an AP, CAPWAP provides a data tunnel to encapsulate data packets to be sent to the AC. These packets can be raw 802.11 packets or 802.11 to 802.3 translated packets. On an AC, CAPWAP provides a control tunnel to support remote AP configuration and management, and WLAN and mobile management.
With CAPWAP, the AC can dynamically configure an AP based on the information provided by the administrator.
CAPWAP supports both IPv4 and IPv6.
Configuring Auto AP
The auto AP feature allows you to create an AP template with the serial ID auto for the APs of the same model on an AC, namely, an auto AP template. When such an AP tries to connect to the AC, the AC creates a temporary AP template for the AP by using the auto AP template. After the AP is associated with the AC, the AC automatically adds the serial ID of the AP into the template. The auto AP feature avoids configuring AP serial IDs, thus simplifying the configuration of large WLANs.
l With auto AP enabled, the AC first searches a match from manually configured templates for a requesting AP. If no match is found, it uses the auto AP template for the AP.
l If multiple ACs exist, a requesting AP associates with the AC that provides a manually configured AP template in which the AP model and serial ID match those of the AP.
Configuring AP Group
Some wireless service providers need to control the access positions of clients. For example, as shown in the figure below, to meet security or billing needs, it is required to connect wireless clients 1, 2 and 3 to the wired network through APs 1, 2 and 3 respectively. To achieve this, you can configure an AP group and then apply the AP group in a user profile.

AP Setup
Adding an AP
Select AP > AP Setup from the navigation tree, and click Create to enter the page for adding an AP, as shown in Figure 1-3.
Table 1-1 shows the configuration items of adding an AP.

Configure an AP
Select AP > AP Setup from
the navigation tree, find the AP to be configured, and click the 
icon in the
Operation column to enter the page for configuring an AP, as shown in Figure 1-4.

|
AP Name |
Displays the name of the AP selected. |
|
Radio Number |
Number of the radios supported by the AP, which takes the value 1 or 2. The value depends on the AP model. |
|
Radio Type |
The value depends on the AP model and radio type. |
|
Serial ID |
Set a serial ID for the AP. l auto: If selected, the AP serial ID is automatically found. This option is used together with the auto AP function. For how to configure auto AP, refer to Configuring Auto AP. l manual: You need to type an AP serial ID.
The serial ID is the unique identity of the AP. If the AP has connected to the AC, changing or deleting its serial ID will render the CAPWAP tunnel down and the AP needs to discover the AC to connect again. |

Advanced setting
Select AP > AP Setup from the navigation tree, find the AP to be configured, and click the corresponding icon in the Operation column, and click the + mark before Advance Setup to enter the page for advanced AP setup, as shown in Figure 1-5.

Broadcast Probe |
l enable: Enables the AP to respond to broadcast probe requests. l disable: Disables the AP from responding to broadcast probe requests. By default, the AP responds to broadcast probe requests. |
|
Configuration File |
Specifies a name for the configuration file in the flash and maps the specified configuration file to the AP. When local forwarding is enabled, you can use the configuration file to configure the AP. |
|
Jumbo Frame Size |
Set the maximum size of jumbo frames. |
|
AP Echo Interval |
Set the interval for sending echo requests. There is a keep-live mechanism between AP and AC, to confirm whether the control channel is working or not. To keep the control channel alive, an AP periodically sends echo requests to an AC. The AC responds to echo requests by sending echo responses. This mechanism is used to make an AC be aware of AP offline. |
|
Client Alive Time |
Set the client keep alive interval. The keep-alive mechanism is used to detect client offline. Normally, when a client gets offline, it sends an offline packet to the AC, and the AC will remove the client after receiving the packet. However, if a client gets offline due to power failure or crash, the client cannot notify the AC. In this case, the AC will keep the client information in its client list, and the client information occupies the AC’s memory and thus reduces AC performance. Therefore, to prevent this situation, you can enable the keep-alive function on the AC. With this function enabled, the AC will periodically scan the client. If the AC does not receive any response, the AC considers the client offline, and removes the client from its client list. By default, the client keep-alive functionality is disabled. |
|
Client Free Time |
Maximum interval for which the link between the AP and a client can be idle. If a client is idle for more than the specified interval, that is, if the AP does not receive any data from the client within the specified interval, the client will be removed from the network. |
|
AP CAR |
You can set this parameter only when you select the check box before AP CAR. By default, no CAR is set for an AP. |
|
CIR |
Committed information rate, in kbps. |
|
CBS |
Committed burst size, in bytes. By default, the CBS is the number of bytes transmitted in 500 ms at the rate of CIR. For example, if CIR is 100, CBS is 500000 bytes by default. |
