Chapter 4 Troubleshooting 1240AG Series Lightweight Access Points
Guidelines for Using Cisco Aironet Lightweight Access Points
Guidelines for Using Cisco Aironet Lightweight Access Points
Keep these guidelines in mind when you use a 1240 series lightweight access point:
•The access points can only communicate with Cisco 2006 series wireless LAN controllers or 4400 series controllers.
Note Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series wireless LAN controllers are not supported because they lack the memory required to support access points running Cisco IOS software.
•The access points do not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it.
•The access points support eight Basic Service Set Identifiers (BSSIDs) per radio and a total of eight wireless LANs per access point. When an access point associates to a controller, only wireless LANs with IDs 1 through 8 are pushed to the access point.
•The access points do not support Layer 2 LWAPP. They must get an IP address and discover the controller using DHCP, DNS, or IP subnet broadcast.
•The access point console port is enabled for monitoring and debug purposes (all configuration commands are disabled when 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 the access point to find and join a controller. For additional information, refer to the “Configuring DHCP Option 43 for Lightweight Access Points” section on page
