1.0  Introduction

   This module contains managed objects which describe the following:

      o   The APPN node (either an APPN network node or an APPN end node)

      o   The connections of the node to other SNA nodes

      o   The APPN network topology (as reflected in the network topology
          database that is replicated in each APPN network node.

   This module does not describe the SNA logical units (LUs) served by
   the APPN node nor does it describe the sessions between LUs.  Managed
   objects for that information are under development.
