Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

1.  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 APPN (Advanced Peer-to-Peer Networking)
   capabilities.  This memo identifies managed objects for the APPN
   protocol.

2.  The SNMPv2 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.

3.  Overview

   This document identifies a set of objects for monitoring the
   configuration and active characteristics of devices with APPN
   capabilities, and for controlling certain characteristics.  APPN is
   the aspect of Systems Network Architecture (SNA) that supports peer-
   to-peer networking.  These networks transport both independent and
   dependent LU session traffic.  See the SNANAU APPC MIB [7] and the
   SNA NAU MIB [8] for management of these sessions.  See also the DLUR
   MIB[9], and the HPR MIB[10] for management of extensions to the APPN
   architecture.  In this document, we describe APPN managed objects.

   An APPN network comprises various types of nodes, and transmission
   groups (TGs) that connect the nodes. Network nodes (NNs) provide
   directory and routing functions for session establishment.  NNs may
   be session end points or intermediate nodes in a session.  A border
   node is a type of network node that connects networks together for
   session establishment without fully merging them.  End nodes (ENs)
   are session end points that receive directory and routing functions
   from network nodes, over control-point to control-point (CP-CP)
   sessions.  Low-entry networking (LEN) nodes are also session end
   points, but do not support CP-CP sessions, and therefore need
   additional manual configuration definitions to establish sessions in
   an APPN network.  ENs and LEN nodes may have minimal directory and
   routing functions to establish control sessions (ENs) or to connect
   into the APPN network (LEN nodes).  Virtual routing nodes (VRNs) are
   not really nodes, but rather common definitions among actual nodes in
   a shared transport facility such as a local area network (LAN) that
   allow these actual nodes to temporarily establish a logical link with
   one another without defining each other's link-level addressing
   information.

   Ports and link stations are the node's interface to the data link
   control (DLC), which provides the physical transport, or to another
   protocol such as Data Link Switching (DLSw), which provides transport
   over an IP network.  See the SNADLC SDLC MIB[11], the SNADLC LLC
   MIB[12], and the DLSw MIB[13].  A link station uses a port to make a
   connection to another node.  This connection establishes a TG between
   the two nodes.
