CISCO-WIRELESS-NOTIFICATION-MIB

This MIB is intended to be implemented on those Network
        Management applications that manage a network of wireless
        devices through the Controller and send relevant management
        information to Northbound Operation Support Systems. The
        Northbound OSS, with the information received shall present a
        consolidated view of the whole network of wireless devices. 
        
        The NM learns the status of the managed devices from the
        Controller through interfaces like the SNMP, and raises
        events. Depending upon the event severity, alerts are raised
        for the events. The alert/event information is sent to the
        Northbound OSS in the form of SNMP Notifications. This MIB
        defines these Notifications.
        
        The MIB objects cWNotificationDescription,
        cWNotificationSpecialAttributes and cWNotificationVirtualDomains
        have been defined to have a maximum size of 1024.   The bigger
        size is required for the following reasons.
        
        1. If the size is reduced, the information intended to be 
        sent to the Northbound applications will be truncated / lost. 
        
        2. Networks using UDP are better in handling fragmentation than
        before. 
        
        3. In case if the implementation is used in those networks that
        can't handle Notifications of a larger size,  the intent is to
        suggest the use of the TCP as the transport protocol for SNMP as
        against the UDP. 
        
        4. The respective objects may not have the maximum defined range
        at all the times.  The higher range is just to accommodate those
        cases where the size can hit the maximum value. 
        
        The relationships between NCS, CC, AP, MN and
        Mgmt-Appl can be depicted as follows :

                           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 to.
        
        Alert
        
        An alert is an NM response to one or more related Events from
        Managed Object. If the Event learnt is severe enough to let the
        user know about, the NM raises an alert i.e if event has one of
        the following severity critical, major, minor or warning. One
        or more Events can result in a single alert being raised.
        
        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'.
        
        Event
        
        An Event is an occurrence or detection of some condition in and
        around the network. Event can be generated by the NM
        corresponding to traps received or through polling the managed
        object.
        
        Light Weight Access Point Protocol ( LWAPP )
        
        This is a generic protocol that defines the
        communication between the Access Points and the
        Controllers.
        
        Managed Object
        
        Managed Objects are used to represent those entities being 
        managed by the NM.  It could be an AP, WLAN, Controller or 
        an MN.
        
        Mobile Node ( MN )
        
        Mobile Nodes are roaming 802.11 wireless devices that would 
        associate to an AP to get their uplink to the wired network. 
        Mobile Nodes are also known as clients.
        
        Network Management Application ( NM )
        
        Application which manages network of managed objects using
        SNMP. It provides network management functions of FCAPS -
        Fault, Configuration, Accounting, Performance and Security to
        manage the network.
        
        Notification
        
        NM application like NCS sends Notifications defined through
        this MIB, corresponding to their Alerts and Events to a 
        Northbound OSS to provide a consolidated view.
        
        Operations Support Systems ( OSS )
        
        Management applications in the network that receive
        Notifications from NM (like NCS) and provide consolidated view 
        of the whole network of wireless devices.
        
        Received Signal Strength Indicator ( RSSI )
        
        A measure of the strength of the signal as observed by the
        entity that received it, expressed in 'dbm'.
        
        Signal-Noise Ratio ( SNR )
        
        A measure of the quality of the signal relative to the strength
        of noise expressed in 'dB'.
        
        Virtual Domain
        
        A NM's Virtual Domain is a logical grouping that consists of a
        set of managed objects like Controllers, APs, WLANs, maps etc.
        It restricts a user's view to information relevant to these
        managed objects. Through a virtual domain, an administrator can
        ensure that users are only able to view the managed objects and
        maps for which they are responsible. A managed object can belong
        to more than one virtual domain.
        
        Network Control System ( NCS )
        
        Network Control System (NCS) is a converged platform for 
        wired, wireless, and security policy management in a single 
        solution for faster troubleshooting and more efficient network 
        operations. 
        
        
        Wireless LAN ( WLAN ) 
        
        A WLAN refers to the network of IEEE 802.11 complaint wireless 
        devices within mutual communication range of each other via 
        the wireless medium.
        
        REFERENCE
        
        [1] Wireless LAN Medium Access Control (MAC) and
            Physical Layer (PHY) Specifications.
        
        [2] IEEE 802.11 - The original 1 Mbit/s and 2 Mbit/s, 
            2.4 GHz RF and IR standard.
