      STATUS current
      DESCRIPTION
          "When it has been enabled, this notification is generated by an
          APPN node whenever an ISR session passing through the node is
          taken down, regardless of whether the session went down
          normally or abnormally.  Its purpose is to allow a management
          application (primarily an accounting application) that is
          monitoring the ISR counts to receive the final values of these
          counts, so that the application can properly account for the
          amounts the counts were incremented since the last time the
          application polled them.  The appnIsInSessUpTime object
          provides the total amount of time that the session was active.

          This notification is not a substitute for polling the ISR
          counts.  In particular, the count values reported in this
          notification cannot be assumed to be the complete totals for
          the life of the session, since they may have wrapped while the
          session was up.

          The session to which the objects in this notification apply is
          identified by the fully qualified CP name and PCID that make up
          the table index.  An instance of this notification will contain
          exactly one instance of each of its objects, and these objects
          will all belong to the same conceptual row of the
          appnIsInTable.

          Generation of this notification is controlled by the same
          object in the APPN MIB, appnIsInGlobeCtrAdminStatus, that
          controls whether the count objects themselves are being
          incremented."

      STATUS current
      DESCRIPTION
          "When it has been enabled, this notification makes it possible
          for an APPN topology application to get asynchronous
          notifications of local TG operational state changes,
          and thus to reduce the frequency with which it polls
          for these changes.

          This notification is sent whenever there is a change to
          the appnLocalTgOperational object in a row of the
          appnLocalTgTable.  This notification is only sent for row
          creation if the row is created with a value of 'true' for
          appnLocalTgOperational.  This notification is only sent for
          row deletion if the last value of appnLocalTgOperational was
          'true'.  In this case, the value of appnLocalTgOperational
          in the notification shall be 'false', since the deletion of
          a row indicates that the TG is no longer operational.

          The notification is more than a simple 'poll me now' indication.
          It carries both a count of local TG topology changes, and the
          current operational state itself.  The count of changes allows an
          application to detect lost notifications, either when polling
          or upon receiving a subsequent notification, at which point it
          knows it must retrieve the entire appnLocalTgTable again.
          This is the same count as used in the appnLocalCpCpStateChangeTrap.
          A lost notification could indicate a local TG CP-CP session state
          change or an operational state change.

          Generation of this notification is controlled by the
          appnTrapControl object."
