wireless lan Recovery IOS : This feature allows a Cisco autonomous access point to communicate with a Cisco Wireless LAN Controller in order to receive a full Lightweight Access Point Protocol (LWAPP) image. Access points shipping with LWAPP or selected autonomous access points upgraded from autonomous to lightweight mode use the LWAPP upgrade and recovery support feature to receive their full LWAPP image from the controller. The LWAPP upgrade and recovery support feature is also used as a recovery image if the full LWAPP image becomes corrupted. Access points using the LWAPP upgrade and recovery support feature have limited functionality and their radios are disabled until the Cisco Wireless LAN Controller sends them the full LWAPP image.
Fully functional CAPWAP files, identified by the k9w8 string in their name. When booting this image, the AP is fully functional and can join a controller to obtain its configuration.
Recovery mode CAPWAP files, identified by the rcvk9w8 string in their name. These files are smaller than the fully functional k9w8 CAPWAP files. When booting rcvk9w8 files, the AP can join a controller to download a fully functional image. The AP will then reboot, use the fully functional image and rejoin a controller to obtain its configuration.
