It reflects changes which are the   result of operational experience based onRFC 1289.   When used in conjunction with the structure of management information   (STD 16,RFC 1155), the management information base for network   management of TCP/IP-based internets (STD 17,RFC 1213) and the   Simple Network Management Protocol (STD 15,RFC 1157), it will be   possible to provide integrated network management of combined TCP/IP   and DECnet Phase IV based internets.  This document was produced by   the DECnet Phase IV MIB working group of the Internet Engineering   Task Force (IETF).   With the adoption of The Simple Network Management Protocol (STD 15,RFC 1157), the management information base for network management of   TCP/IP-based internets (STD 17,RFC 1213), and the structure ofDECnet Phase IV MIB Working Group                               [Page 1]

RFC 1559                  DECnet Phase IV MIB              December 1993   management information (STD 16,RFC 1155), by the Internet, and a   large number of vendor implementations of these standards in   commercially available products, it became possible to provide a   higher level of effective network management in TCP/IP-based   internets than previously available. With the growth in the use of   these standards, network managers desired to use this environment as   a base for providing integrated network management of multi-protocol   networks.   DECnet Phase IV is one widely used protocol which often coexists in   IP-based internets. This memo provides the mechanisms by which IP-   based management stations can effectively manage DECnet Phase IV   based systems (especially router products) in an integrated fashion   through the use of the standard Internet SMI, MIB and Simple Network   Management Protocol.   DECnet Phase IV objects have been defined to be used in conjunction   with the Internet MIB to allow access and control of these new   objects by the Internet community. Additional support for other   DECnet-based protocols such as RBMS (Remote Bridge Management   Software) or other Digital Equipment Corporation specific hardware   platforms is not included in this document.2.  The Network Management Framework   The Internet-standard Network Management Framework consists of three   components.  They are:   o STD 16,RFC 1155 which defines the SMI, the mechanisms used for     describing and naming objects for the purpose of management.     STD 16,RFC 1212 defines a more concise description mechanism,     which is wholly consistent with the SMI.   o STD 17,RFC 1213 defines MIB-II, the core set of managed objects     for the Internet suite of protocols.   o STD 15,RFC 1157 which defines the SNMP, the protocol used for     network access to managed objects.   The Framework permits new objects to be defined for the purpose of   experimentation and evaluation.2.1  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 type is named by anDECnet Phase IV MIB Working Group                               [Page 2]

RFC 1559                  DECnet Phase IV MIB              December 1993   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.3.  Selected Objects   The objects included in this memo have been created from the DIGITAL   Network Architecture Network Management Functional Specification   Version 4.0.0, dated July 1983. An attempt has been made to provide a   reasonable ordering of these variables into groups. These groups are:        System Group        Network Management Group        Session Group        End Group        Routing Group        Circuit Group        DDCMP Group        DDCMP Multipoint Control Group        Ethernet Group        Counters Group        Adjacency Group        Line Group        Non Broadcast Line Group        Area Group   An effort has also been made to preserve the original syntax of each   object wherever possible, for example, a DECnet Phase IV object is   Executor State. This was originally coded as a NICE (Network   Information and Control Exchange) data type which is a coded single   field object of 1 byte in length. When converted for inclusion into   the Internet MIB using the Internet SMI, it became an enumerated   integer.   All objects in this memo are described using the standard Internet   SMI and BER of STD 16,RFC 1155. A complete description of an object   will include the name, syntax and encoding. Just as with objects   supported in the MIB (STD 17,RFC 1213), an object name is identified   with an object identifier which has been administratively assigned.   This identifies an Object Type. When an object type is combined with   a specific instance, the particular object is uniquely identified.   The use of Object Descriptors in this memo is consistent with that of   STD 17,RFC 1213 - they are text strings meant to be read by humans.   The descriptors have been taken from the original DIGITAL Network   Architecture Network Management Functional Specification Version   4.0.0 Dated July 1983 which defined DECnet Phase IV objects.

RFC 1559                  DECnet Phase IV MIB              December 1993   names were then massaged to put them in a form as consistent as   possible with object type names listed in the standard Internet MIB.   Object defintion information is also taken directly from the Network   Architecture Network Managment Functional Specification cited above   wherever possible. In this document, EXECUTOR is intended to   reference only the DECnet software and is not intended to effect any   other protocols which may be running on the system.4.  Textual Conventions   New datatypes have been introduced as a textual conventions in this   DECnet Phase IV MIB document. The purpose of these additions is to   facilitate understanding of new objects in this MIB. No changes to   the SMI or the SNMP are necessary to support these conventions which   are described in 5 (Definitions).5.
