Guidelines for Using Cisco Aironet Lightweight Access Points Keep these guidelines in mind when you use an 1140 series lightweight access point: • The access point can only communicate with Cisco controllers, such as the 2106 series wireless LAN controllers or 4400 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 to 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 31. Checking the Access Point LED Figure 4 shows the location of the access point Status LED.
