CH A P T E R 7 Controlling Lightweight Access Points This chapter describes the Cisco lightweight access points and explains how to connect them to the controller and manage access point settings.
Chapter 7 Controlling Lightweight Access Points Access Point Communication Protocols Access Point Communication Protocols In controller software release 5.2 or later, Cisco lightweight access points use the IETF standard Control and Provisioning of Wireless Access Points protocol (CAPWAP) to communicate between the controller and other lightweight access points on the network. Controller software releases prior to 5.2 use the Lightweight Access Point Protocol (LWAPP) for these communications.
Chapter 7 Controlling Lightweight Access Points Access Point Communication Protocols with one discovery type (CAPWAP or LWAPP) exceeds the maximum discovery count and the access point does not receive a discovery response, the discovery type changes to the other type. For example, if the access point does not discover the controller in LWAPP, it starts the discovery process in CAPWAP.
Chapter 7 Controlling Lightweight Access Points Access Point Communication Protocols • DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to the access points. Cisco switches support a DHCP server option that is typically used for this capability. For more information about DHCP option 43, see the “Using DHCP Option 43 and DHCP Option 60” section on page 7-25. • DNS discovery—The access point can discover controllers through your domain name server (DNS).
