           "This variable defines current operating mode that BFD
            session is running in.            
            
            The primary mode which the BFD session runs in is known as 
            Asynchronous mode.  In this mode, the systems periodically 
            send BFD Control packets to one another, and if a number of
            those packets in a row are not received by the other system, 
            the session is declared to be down.
   
            The second mode is known as Demand mode.  In this mode, it is 
            assumed that each system has an independent way of verifying 
            that it has connectivity to the other system.  Once a BFD 
            session is established, the systems stop sending BFD Control 
            packets, except when either system feels the need to verify 
            connectivity explicitly, in which case a short sequence of BFD 
            Control packets is sent, and then the protocol quiesces.
            
            An adjunct to both modes is the Echo function.  When the Echo
            function is active, a stream of BFD Echo packets is transmitted 
            in such a way as to have the other system loop them back through 
            its forwarding path. If a number of packets of the echoed data 
            stream are not received, the session is declared to be down.  
            The Echo function may be used with either Asynchronous or 
            Demand modes.
   
            The 'asynchModeWOEchoFun' indicates this BFD session operates in 
            the Asynchronous mode, and doesn't support the Echo Function.
            
            The 'demandModeWOEchoFunction' indicates this BFD session operates in 
            the Demand mode, and doesn't support the Echo Function.

       DESCRIPTION
           "The state of the running BFD session.
           
            There are three states through which a session normally 
            proceeds, two for establishing a session (Init and Up) 
            and one for tearing down a session (Down.)  This allows 
            a three-way handshake for both session establishment and 
            session teardown (assuring that both systems are aware of 
            all session state changes.)  A fourth state (AdminDown)
            exists so that a session can be administratively put down 
            indefinitely.
            
            The Down state means that the session is down (or has just been 
            created.) A session remains in Down state until the remote 
            system indicates that it agrees that the session is down by 
            sending a BFD Control packet with the State field set to 
            anything other than Up.  If that packet signals Down state, 
            the session advances to Init state;  if that packet signals 
            Init state, the session advances to Up state.
            
            Init state means that the remote system is 0communicating, 
            and the local system desires to bring the session up, but 
            the remote system does not yet realize it.  A session will 
            remain in Init state until either a BFD Control Packet is 
            received that is signaling Init or Up state (in which case 
            the session advances to Up state) or until the detection time 
            expires, meaning that communication with the remote system 
            has been lost (in which case the session advances to Down
            state.)

            Up state means that the BFD session has successfully been
            established, and implies that connectivity between the systems 
            is working.  The session will remain in the Up state until either 
            connectivity fails, or the session is taken down administratively.
            If either the remote system signals Down state, or the detection 
            time expires, the session advances to Down state.

            AdminDown state means that the session is being held 
            administratively down.  This causes the remote system to enter 
            Down state, and remain there until the local system exits 
            AdminDown state.
