CISCO-LWAPP-CCX-RM-MIB
AI MIB Summary
The CISCO-LWAPP-CCX-RM-MIB enables monitoring and management of Cisco Lightweight Access Point Protocol (LWAPP) Central Controllers to track Radio Management metrics and Cisco Compatible Extensions (CCX) status for associated lightweight Access Points and Mobile Nodes. This module provides visibility into 802.11 radio environment parameters, client roaming states, and proprietary CCX feature implementations to ensure optimal wireless service quality.
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 for CCX related features as specified in the CCX specifications.
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.
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'.
Cisco Compatible eXtensions (CCX)
Wireless LAN Access Points (APs) manufactured by Cisco Systems have features and capabilities beyond those in related standards (e.g., IEEE 802.11 suite of standards, Wi-Fi recommendations by WECA, 802.1X security suite, etc). A number of features provide higher performance. For example, Cisco AP transmits a specific Information Element, which the clients adapt to for enhanced performance. Similarly, a number of features are implemented by means of proprietary Information Elements, which Cisco clients use in specific ways to carry out tasks above and beyond the standard. Other examples of feature categories are roaming and power saving.
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. The terms 'Mobile node' and 'client' are used interchangeably.
Radio Management (RM)
This term refers to managing the 802.11 radio environment to provide the best quality service to to the 802.11 wireless clients.
Service Set Identifier ( SSID )
SSID is a unique identifier that APs and clients use to identify with each other. SSID is a simple means of access control and is not for security. The SSID can be any alphanumeric entry up to 32 characters.

clcrClientBeaconReportTableThis table reports the received signal power as seen
by a wireless client when conducting radio
measurements. Clients measure the received signal
power by observing the beacon requests and probe
response messages on all the specified channels and
pass them to the APs through beacon reports.
An entry is added to the table by the agent when the
beacon report sent by the client arrives at the dot11
interface of an AP. An existing entry for a client
gets over-written when the subsequent reports arrive
at an AP from that client. The term 'client' here
refers to all the wireless CCX compliant devices like
mobile stations, tags etc.
An entry is deleted from this table when the particular
client dissociates from the AP. The entry also gets
deleted when the AP dissociates from the controller. SEQUENCE OF ClcrClientBeaconReportEntry .1.3.6.1.4.1.9.9.520.1.4.1 |
