    DESCRIPTION
        "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.

         the Asynchronous mode, and also supports 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."
