Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working network.
8Troubleshooting
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.com.
Guidelines for Using Cisco Aironet Lightweight Access Points
Keep these guidelines in mind when you use 3502P lightweight access points:
•The access point can only communicate with Cisco wireless LAN controllers, such as 2100, 4400, and 5500 series controllers.
•The access point does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point joins it.
•CAPWAP does not support Layer 2. The access point must get an IP address and discover the controller using Layer 3, DHCP, DNS, or IP subnet broadcast.
•The access point console port is enabled for monitoring and debug purposes. All configuration commands are disabled when the access point is connected to a controller.
Using DHCP Option 43
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. For additional information, refer to the “Configuring DHCP Option 43 and DHCP Option 60” section on page 26.
