Overview
The Cisco Aironet 1000 Series Lightweight Access Points (hereafter called access points) combine mobility and flexibility with the
The access point contains two integrated radios: a
In the Cisco Centralized Wireless LAN Architecture, access points operate in the lightweight mode (as opposed to autonomous mode). The access points associate to a controller. The controller manages the configuration, firmware, and control transactions such as 802.1x authentication. In addition, all wireless traffic is tunneled through the controller.
LWAPP is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging for setup and path authentication and
In an LWAPP environment, a lightweight access point discovers a controller by using LWAPP discovery mechanisms and then sends it an LWAPP join request. The controller sends the access point an LWAPP join response allowing the access point to join the controller. When the access point is associated with a controller, it downloads new operating system software if the versions on the access point and controller do not match. After an access point is associated to a controller, you are able to reassign it to any controller on your network.
LWAPP secures the control communication between the access point and controller by means of a secure key distribution, utilizing X.509 certificates on both the access point and controller.
