Note A Master Cisco wireless LAN controller should be used only for configuring access
points and not in a working network.
9 Troubleshooting
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 an 1040 series lightweight access point:
•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 32.
