Description: This MIB is intended to be implemented on all those devices operating as Central controllers, that terminate the Light Weight Access Point Protocol tunnel from Cisco Light-weight LWAPP Access Points.

The relationship between the controller and the LWAPP APs is depicted as follows:

GLOSSARY

Access Point ( AP )

An entity that contains an 802.11 medium access control ( MAC ) and physical layer ( PHY ) interface and provides access to the distribution services via the wireless medium for associated clients.

LWAPP APs encapsulate all the 802.11 frames in LWAPP frames and sends it to the controller to which it is logically connected.

Wireless LAN Controller (WLC)

Wireless LAN Controller are legacy mobility device which can participate in the new mobility architecture.

Central Controller ( CC )

The central entity that terminates the LWAPP protocol tunnel from the LWAPP APs. Throughout this MIB, this entity also referred to as 'controller'.

Light Weight Access Point Protocol ( LWAPP )

This is a generic protocol that defines the communication between the Access Points and the controllers.

Mobile Node ( MN )

A roaming 802.11 wireless device in a wireless network associated with an access point.
