Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working network.

If you experience difficulty getting your access point installed and running, look for a solution to your problem in this guide or in additional access point documentation. These, and other documents, are available on Cisco. Keep these guidelines in mind when you use series lightweight access points:. You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling them to find and join a controller.

The location of the access point status LED is shown in Figure 5. Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. The access point status LED indicates various conditions and are described in Table 1. Normal operating condition, but no wireless client associated. Normal operating condition, at least one wireless client association. Configuration recovery in progress MODE button pushed for 2 to 3 seconds.

Ethernet failure or image recovery MODE button pushed for 20 to 30 seconds. Software failure; try disconnecting and reconnecting unit power. You do not need to enable any debug commands on the controller because all of the CAPWAP error messages can be viewed from the syslog server itself. The state of the access point is not maintained on the controller until it receives a CAPWAP join request from the access point.

Therefore, it can be difficult to determine why the CAPWAP discovery request from a certain access point was rejected. In order to troubleshoot such joining problems without enabling CAPWAP debug commands on the controller, the controller collects information for all access points that send a discovery message to it and maintains information for any access points that have successfully joined it.

The controller collects all join-related information for each access point that sends a CAPWAP discovery request to the controller. Collection begins with the first discovery message received from the access point and ends with the last configuration payload sent from the controller to the access point. You can view join-related information for the following numbers of access points:.

When the controller is maintaining join-related information for the maximum number of access points, it does not collect information for any more access points. An access point sends all syslog messages to IP address If any of these conditions are met and the access point has not yet joined a controller, you can also configure a DHCP server to return a syslog server IP address to the access point using option 7 on the server. The access point then starts sending all syslog messages to this IP address.

When the access point joins a controller for the first time, the controller sends the global syslog server IP address the default is After that, the access point sends all syslog messages to this IP address until it is overridden by one of the following scenarios:. You can configure the syslog server for access points and view the access point join information only from the controller CLI. A detailed explanation of the join process is on Cisco.
