bfdSessUp NOTIFICATION-TYPE
     OBJECTS {
         bfdSessDiag, -- low range value
         bfdSessDiag  -- high range value
     }
     STATUS     current
     DESCRIPTION
         "This notification is generated when the
          bfdSessState object for one or more contiguous
          entries in bfdSessTable are about to enter the up(4)
          state from some other state.  The included values of
          bfdSessDiag MUST both be set equal to this
          new state (i.e., up(4)).  The two instances of
          bfdSessDiag in this notification indicate the range
          of indexes that are affected.  Note that all the indexes
          of the two ends of the range can be derived from the
          instance identifiers of these two objects.  For the
          cases where a contiguous range of sessions
          have transitioned into the up(4) state at roughly
          the same time, the device SHOULD issue a single
          notification for each range of contiguous indexes in
          an effort to minimize the emission of a large number
          of notifications.  If a notification has to be
          issued for just a single bfdSessEntry, then
          the instance identifier (and values) of the two
          bfdSessDiag objects MUST be identical."
     ::= { bfdNotifications 1 }

     DESCRIPTION
         "This notification is generated when the

     ::= { bfdNotifications 1 }

Notes
-----
The bfdSessUp and bfdSessDown must report the bfdSessIndex range for which the 
Session State has changed and not the bfdSessDiag.
