CISCO-LWAPP-MOBILITY-MIB

This MIB is intended to be implemented on all those
        devices operating as Central Controllers (CC) that
        terminate the Light Weight Access Point Protocol
        tunnel from Light-weight LWAPP Access Points.
        
        This MIB provides configuration and status information
        about the 802.11 WLAN mobility.                 
        
        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 it to the controller to which
        it is logically connected.
        
        Basic Service Set Identifier (BSSID)
        
        The identifier for the service set comprising of
        all the 802.11 stations under the control of
        one coordinating Access Point.  This identifier
        happens to be the MAC address of the dot11 radio
        interface of the Access Point.  The wireless
        clients that associate with the Access Point
        get the wired uplink through this particular 
        dot11 interface. 
        
        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
        Central Controller. 
        
        Mobile Node ( MN )
        
        A roaming 802.11 wireless device in a wireless
        network associated with an access point. 
        
        Mobility 
        
        Concept by which a Mobile Node can roam from one 
        Access Point to another Access Point, across multiple
        Central Controllers, without need for repeated 
        authentication. 
        
        Mobility Group
        
        A set of Central Controllers which exchange Mobile 
        Node's authentication information, so that the Mobile
        Node upon roaming need not re-authenticate.  
        
        Mobility Anchor
        
        When a Central Controller in the Mobility Group is 
        designated as Mobility Anchor, then all the Mobile 
        Node's traffic is tunnelled to it by other
        Controllers in the Mobility Group.
        
        Guest Tunneling (GT)
        
        The concept of designating a Central Controller in 
        the Mobility Group as Mobility Anchor, so that all
        the Mobile Node's traffic is tunnelled to it by other
        Controllers in the Mobility Group.              
        
        Station Management (SMT)
        
        This term refers to the internal management of the
        802.11 protocol operations by the AP to work
        cooperatively with the other APs and 802.11
        devices in the network.
        
        Ethernet over Internet Protocol (EoIP)
        
        Ethernet over IP (EoIP) is a protocol that creates 
        an Ethernet tunnel between two routers on top of an
        IP connection. The EoIP interface appears as an 
        Ethernet interface.
        
        Reverse path filtering (RPF) 
        
        Reverse path filtering (RPF) is a feature provided
        by most modern Internet Protocol routers, which may
        be used to reduce the risk of customers attacking
        other internet hosts. One of the problems network
        service providers face today is hackers generating
        packets with fake source IP addresses, a technique
        known as spoofing. This is often done in order to
        initiate a denial-of-service attack against another
        internet host or network.
        Since the source IP addresses of the incoming packets
        change, often randomly, and for every packet, the
        target of such an attack can't easily filter out the
        attacking packets. However, the source of the attack,
        i.e. the network service provider of the attacking 
        host, has a simple way to stop such packets from ever
        leaving its network. A router always knows which 
        networks are reachable via any of its interfaces. 
        By checking the source IP address of all packets 
        coming in via an interface against the networks known
        to be behind that interface, the router can simply 
        drop packets that aren't supposed to come from there.
        Hence, reverse path filtering filters packets 
        according to the 'reverse path' to their source 
        address. If the path back to the source address 
        does not match the path the packet is coming from,
        it is dropped.
