CISCO-LWAPP-RRM-MIB
AI MIB Summary
The CISCO-LWAPP-RRM-MIB provides management and monitoring capabilities for Cisco Central Controllers (CC) to track Radio Resource Management (RRM) metrics, including channel utilization, transmit power levels, and interference statistics, across associated Lightweight Access Points (LWAPP APs). This module enables the observation of RRM algorithm performance and the status of the LWAPP tunnels used to encapsulate 802.11 frames between the controller and the access points.
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.
Information provided by this MIB is used to study the RRM on the WLAN.
The relationship between CC and the LWAPP APs can be depicted as follows:

The LWAPP tunnel exists between the controller and the APs. The MNs communicate with the APs through the protocol defined by the 802.11 standard.
LWAPP APs, upon bootup, discover and join one of the controllers and the controller pushes the configuration, that includes the WLAN parameters, to the LWAPP APs. The APs then encapsulate all the 802.11 frames from wireless clients inside LWAPP frames and forward the LWAPP frames to the controller.
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 them to the controller to which it is logically connected.
Light Weight Access Point Protocol ( LWAPP )
This is a generic protocol that defines the communication between the Access Points and the Central Controller.
Mobile Node ( MN )
A roaming 802.11 wireless device in a wireless network associated with an access point. Mobile Node and client are used interchangeably.
Radio Resource Management ( RRM )
RRM is the system level control of co-channel interference and other radio transmission characteristics in wireless communication systems.
