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.
