    Definitions of Managed Objects for SNA Data Link Control (SDLC)
                              using SMIv2

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.

Abstract

   This specification defines an extension to the Management Information
   Base (MIB) for use with SNMP-based network management.  In
   particular, it defines objects for managing the configuration,
   monitoring and control of data link controls in an SNA environment.
   This draft identifies managed objects for SNA Synchronous Data Link
   Control (SDLC) links only.

1.  The SNMPv2 Network Management Framework

   The SNMPv2 Network Management Framework consists of four major
   components.  They are:

      o    RFC 1441 which defines the SMI, the mechanisms used for
           describing and naming objects for the purpose of management.

      o    STD 17, RFC 1213 defines MIB-II, the core set of managed
           objects for the Internet suite of protocols.

      o    RFC 1445 which defines the administrative and other
           architectural aspects of the framework.

      o    RFC 1448 which defines the protocol used for network access
           to managed objects.

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

1.1.  Object Definitions

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the subset of Abstract Syntax Notation One (ASN.1)
   defined in the SMI.  In particular, each object object type is named
   by an OBJECT IDENTIFIER, an administratively assigned name.  The
   object type together with an object instance serves to uniquely
   identify a specific instantiation of the object.  For human
   convenience, we often use a textual string, termed the descriptor, to
   refer to the object type.

2.  Overview

   This memo identifies the proposed set of objects for configuring,
   monitoring, and controlling SDLC ports and link stations.

2.1.  Tables Defined in the SNADLC SDLC MIB

   The SNADLC MIB is composed of two managed entities with three tables
   each.  The two managed entities for SDLC are:

     o    Ports: the physical connection, and

     o    Link Stations: the logical connections on the Port.
