CISCO-LWAPP-RRM-MIB

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. 
        
        Central Controller ( CC )
        
        The central entity that terminates the LWAPP protocol
        tunnel from the LWAPP APs.  Throughout this MIB,
        this entity is also referred to as '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.
        
        Received Signal Strength Indicator ( RSSI )
        
        A measure of the strength of the signal as
        observed by the entity that received it,
        expressed in 'dbm'.
        
        Coverage Hole Detection ( CHD )
        
        If clients on an Access Point are detected at low 
        RSSI levels, it is considered a coverage hole  
        by the Access Points. This indicates the existence 
        of an area where clients are continually getting poor 
        signal coverage, without having a viable location to 
        roam to.
        
        Dynamic Channel Assignment (DCA)
        
        Dynamic channel assignment (DCA) is used by the controller 
        to minimize adjacent channel interference between 
        access points.
        
        Dynamic Frequency Selection (DFS)
        
        Dynamic frequency selection (DFS) is used by the controller 
        to detect radar signals and avoid interfering with them.
        
        RRM RF Grouping 
        
        Radio Resource Management (RRM) allows the Cisco WLAN controllers 
        to continuously analyze the existing RF environments, 
        and automatically adjust the AP power and channel 
        configurations in order to help alleviate overlapping channel 
        interference, signal coverage problems, and so forth.
        
        An RF group is a cluster of Cisco wireless controllers 
        that coordinates its RRM calculations on a per 802.11-network basis. 
        An RF group exists for each 802.11 network type. 
        Clustering controllers into RF groups enables 
        the RRM algorithms to scale beyond a single controller.
        
        
        +....+  Auto-leader      +....+ Auto-member
        +    +  <------------->  + C2 +
        +    + (802.11a network) +....+   
        + C1 +   
        +    +           
        +    +  Static-member    +....+ Static-leader
        +    +  <------------->  + C3 +
        +....+ (802.11b network) +....+
        
        With the help of above diagram, different aspects of
        RRM RF Grouping can be explained. Grouping can be
        configured for 3 modes.
        
        1) Automatic 
        2) Static
        3) Off
        
        If the mode is 'Automatic', the controllers automatically 
        form groups and elect leaders to perform better 
        dynamic parameter optimization. If the mode is 'Static', 
        user can select one controller as the group leader and 
        configure the group members manually. If the mode 
        is 'Off', no dynamic grouping occurs. Each controller 
        optimizes only its own APs' parameters.
        
        In the above diagram, controller C1 forms a RF group with
        controller C2 in 802.11a network. And with controller C3,
        it forms a different group in 802.11b network. 
        
        For the 802.11a network, the gorup mode is selected as 'Automatic'.
        So between C1 and C2 controllers, one would be selected as 
        group leader and the other controller as member automatically by
        the algorithm. In the above case C1 is the group leader and C2 is
        the group member.
        
        Now for 802.11b network, group mode is selected as 'Static'.
        Also the user has manually configured C3 as the leader in this group 
        and C1 was added to this group as member.
