Introduction This memo defines a set of DECnet Phase IV extensions that have been created for the Internet MIB. It reflects changes which are the result of operational experience based on RFC 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 of DECnet 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 an DECnet 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. These DECnet Phase IV MIB Working Group [Page 3] 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.

These changes include: (1) Ranges have been added on all PhivCounter types to remove ambiguity which might otherwise have occurred. (2) Made clear that all indexes start with 1 and count up. (3) Spelling and typographic changes. (4) Changes to improve consistency with other documents including the removal of subranging within definitions of sequences defining table entries. (5) Updated compliance text to conform to current practice. (6) Fixed discrepancy between description and range clause for phivControlMaxBuffs. (7) Added a space that was missing between SYNTAX and INTEGER in the phivRouteType object. (8) Both phivRouteType and phivRouteSystemAddr have been made obsolete. They have been replaced with phivRouteRoutingType and phivRouteSystemAddress which are both read-write objects. DECnet Phase IV MIB Working Group [Page 67] RFC 1559 DECnet Phase IV MIB December 1993 (9) A new Adjacency table has been added as adjacency 2. This table is identical to the original except that phivAdjExecListenTimer was not carried into the new version. The existing Adjacency table and all objects in it have been made obsolete. The index to the new table is phivAdjNodeCircuitIndex and phivAdjAddr. (10) Objects phivCountersCountDataBlocksRecd and phivCountersCountDataBlocksSent have both been made obsolete since the DESCRIPTION information overlapped with the phivCountersCountDataBlksRecd and phivCountersCountDataBlksSent objects which have been retained. (11) The following groups have been moved from mandatory to optional status: Session, End, DDCMP, DDCMP Multipoint Circuit Control, Counters, and Non Broadcast Line. 7.
