CISCO-LWAPP-TC-MIB

This module defines textual conventions used
        throughout the Cisco enterprise MIBs
        designed for implementation on Central 
        Controllers that terminate the Light Weight
        Access Point Protocol from LWAPP Access
        Points. 
        
        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.
        
        Advanced Encryption Standard ( AES )
        
        In cryptography, the Advanced Encryption Standard
        (AES), also known as Rijndael, is a block cipher
        adopted as an encryption standard by the US
        government. It is expected to be used worldwide
        and analysed extensively, as was the case with its
        predecessor, the Data Encryption Standard (DES).
        AES was adopted by National Institute of Standards
        and Technology (NIST) as US FIPS PUB 197 in
        November 2001 after a 5-year standardisation
        process.
        
        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'.
        
        Light Weight Access Point Protocol ( LWAPP )
        
        This is a generic protocol that defines the
        communication between the Access Points and the
        Central Controller. 
        
        Management Frame Protection ( MFP )
        
        A proprietary mechanism devised to integrity protect
        the otherwise unprotected management frames of the
        802.11 protocol specification.
        
        Message Integrity Check ( MIC )
        
        A checksum computed on a sequence of bytes and made
        known to the receiving party in a data communication,
        to let the receiving party make sure the bytes
        received were not compromised enroute.
        
        Mobile Node ( MN )
        
        A roaming 802.11 wireless device in a wireless
        network associated with an access point.
        
        Temporal Key Integrity Protocol ( TKIP )
        
        A security protocol defined to enhance the limitations
        of WEP.  Message Integrity Check and per-packet keying
        on all WEP-encrypted frames are two significant
        enhancements provided by TKIP to WEP.
        
        Wired Equivalent Privacy ( WEP )
        
        A security method defined by 802.11. WEP uses a
        symmetric key stream cipher called RC4 to encrypt the
        data packets.
        
        802.11n
        
        802.11n builds upon previous 802.11 standards by 
        adding MIMO (multiple-input multiple-output). MIMO 
        uses multiple transmitter and receiver antennas to 
        allow for increased data throughput through spatial 
        multiplexing and increased range.
        
        Control/Extension Channel 
        
        A single 802.11 channel is 20 MHz wide.  802.11n allows 
        the use of channels of width 40 MHz by combining two 
        20 MHz channels.  The channels are known as the primary 
        or control channel and secondary or extension channel. 
        Both the channels are used for transmission 
        and reception of data.
