CISCO-LWAPP-DOT11-CLIENT-CALIB-MIB
AI MIB Summary
The CISCO-LWAPP-DOT11-CLIENT-CALIB-MIB enables Cisco Centralized Wireless LAN Controllers to monitor and calibrate 802.11 client radio parameters, specifically Signal-to-Noise Ratio (SNR) and Received Signal Strength Indicator (RSSI), for Mobile Nodes associated with LWAPP Access Points. This module facilitates the collection of client-side RF metrics required for dynamic client calibration and interference analysis within the LWAPP tunnel architecture.
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 about the configuration and monitoring of 802.11 wireless clients in the network.
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, Mobile Station(Ms) and client are used interchangeably.
Signal to Noise Ratio ( SNR )
-
It is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power. A ratio higher than 1:1 indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal.
Received Signal Strength Indicator ( RSSI )
It is a measurement of the power present in a received radio signal.
Radio Frequency Identification ( RFID )
It is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object.
