2.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines objects for monitoring and controlling
   network devices with DLUR (Dependent LU Requester) capabilities.
   This memo identifies managed objects for the DLUR protocol.

3.  The SNMP Network Management Framework

   The SNMP Network Management Framework consists of several components.
   For the purpose of this specification, the applicable components of
   the Framework are the SMI and related documents [1, 2, 3], which
   define the mechanisms used for describing and naming objects for the
   purpose of management.

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.

4.  Overview

   This document identifies objects for monitoring the configuration and
   active characteristics of devices with DLUR capabilities.  Dependent
   LU requester/server (DLUR/S) is an extension to the Advanced Peer-
   to-Peer Networking (APPN) architecture that provides dependent LU
   services in APPN networks.  See the SNANAU APPN MIB [4] for
   management of APPN networks.

   The base APPN architecture only provided for transport of data
   between independent logical units (LUs).  However, customers have an
   enormous investment in applications based on dependent LU types.
   DLUR/S provides for support of dependent LU sessions in an APPN
   network.

   A dependent LU server (DLUS) is an APPN node that provides System
   Services Control Point (SSCP) services over an APPN network to remote
   secondary dependent LUs by using SSCP-PU (physical unit) and SSCP-LU
   sessions whose flows are encapsulated on LU 6.2 session flows between
   the DLUS node and the appropriate dependent LU requester (DLUR) node.
   The secondary dependent LUs may be local to the DLUR node, or in
   adjacent type 2.0 or 2.1 nodes.

   The LU 6.2 control sessions between a DLUS node and a DLUR node are
   referred to as a CPSVRMGR pipe.  CPSVRMGR refers to the mode used for
   the sessions.

   In this document, we describe DLUR managed objects.

   The DLUR terms and overall architecture are described in [5].

   Highlights of the management functions supported by the DLUR MIB
   module include the following:

   o    Identifying the node's DLUR capabilities

   o    Displaying the physical units (PUs) this node is supporting

   o    Identification of Dependent LU Servers

   o    Displaying the state of control sessions to Dependent LU
        Servers.

   This MIB module does not support:

   o    Management of dependent LU servers

   o    Configuration of DLUR nodes.
