Internet Draft X.25 Packet Layer MIB February 1992 SNMP MIB extension for the X.25 Packet Layer February 24, 1992 Dean D. Throop (editor) Data General Corporation 62 Alexander Dr. Research Triangle Park, NC 27709 throop@dg-rtp.dg.com 1. Status of this Memo This is a draft document of the x25mib working group. The working group intends to submit a revised version of this document to the RFC editor as an extension to the SNMP MIB. Distribution of this memo is unlimited. Please send comments to the x25mib working group: x25mib@dg-rtp.dg.com 1.1. Revision History February 1992 The February release (Editor's Internal Reference Number 1.14) made many changes. Many of the tables were combined. For example, the x25InfoTable, x25PktStatTable, and x25TmrStatTable were combined into the x25PleTable. The x25ConInfoTable, x25ConStatTable, and x25ConTimrTable were combined into the x25CircuitTable. D. Throop [Page 1] Internet Draft X.25 Packet Layer MIB February 1992 The objects for call parameters were drastically reworked. All call parameters were combined in the x25CallParmTable. Any table, such as the x25PleTable or x25CircuitTable, that needs to reference call parameters identifies an entry in the new table. As part of this the x25ConDefTable was deleted and replaced with the x25PleDefCallParamId. The x25PvcTable was deleted; the x25CircuitStatus object provides similar information about PVCs. The x25ClearedCircuitTable was added to record the status code of cleared circuits. Many object definitions were restructured. For example, the time units for timers was changed from 1/100ths of a second to milliseconds. Some indexes into tables were replaced with object identifiers. Much of the introductory text was changed and the references were changed to match. October 1992 The October release (Editor Internal Reference Number 1.10) made the following changes: Changed x25ConInfoStatus to clarify the description and the pvcResetting(5) value was changed to pvcResetting(6) to avoid a conflict with a previous use of the number 5. The name of the counter object x25TmrStatRetryCountsExceeded was changed to x25TmrStatRetryCountExceededs. The name of the counter object x25TmrStatClearCountsExceeded was changed to x25TmrStatClearCountExceededs. All occurances of Guage were changed to Gauge. Added the x25CallFcltyTable, x25CallFcltyCcittTable, and x25CallParamTable. D. Throop [Page 2] Internet Draft X.25 Packet Layer MIB February 1992 June 1991 The June release corrected some syntax errors and cleaned up some other minor things. April 1991 The April 26 release of this document was the first release. That version was derived from the ISO work on network layer management as presented in ISO/IEC 10733 [11]. 2. Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP- based internets. In particular, it defines objects for managing the Packet Layer of X.25. The objects defined here, along with the objects in the "SNMP MIB extension for LAPB" [9] and the "Definitions of Managed Objects for RS-232-like Hardware Devices" [8], combine to allow management of an X.25 protocol stack. 3. The Network Management Framework The Internet-standard Network Management Framework consists of three components. These components give the rules for defining objects, the definitions of objects, and the protocol for manipulating objects. The network management framework structures objects in an abstract information tree. The branches of the tree name objects and the leaves of the tree contain the values manipulated to effect management. This tree is called the Management Information Base or MIB. The concepts of this tree are given in RFC 1155 "The Structure of Management Information" or SMI [1]. The SMI defines the trunk of the tree and the types of objects used when defining the leaves. RFC 1212, "Towards Concise MIB Definitions" [4], defines a more concise description mechanism that preserves all the principals of the SMI. The core MIB definitions for the Internet suite of protocols can be found in RFC 1156 [2] "Management Information Base for Network Management of TCP/IP-based internets". RFC 1213 [5] defines MIB-II, an evolution of MIB-I with changes to D. Throop [Page 3] Internet Draft X.25 Packet Layer MIB February 1992 incorporate implementation experience and new operational requirements. RFC 1157 [3] defines the SNMP protocol itself. The protocol defines how to manipulate the objects in a remote MIB. The tree structure of the MIB allows new objects to be defined for the purpose of experimentation and evaluation. 4. Objects The definition of an object in the MIB requires an object name and type. Object names and types are defined using the subset of Abstract Syntax Notation One (ASN.1) [6] defined in the SMI [1]. Objects are named using ASN.1 object identifiers, administratively assigned names, to specify object types. The object name, together with an optional object instance, uniquely identifies a specific instance of an object. For human convenience, we often use a textual string, termed the OBJECT DESCRIPTOR, to also refer to objects. Objects also have a syntax that defines the abstract data structure corresponding to that object type. The ASN.1 language [6] provides the primitives used for this purpose. The SMI [1] purposely restricts the ASN.1 constructs which may be used for simplicity and ease of implementation. The encoding of an object type simply describes how to represent an object using ASN.1 encoding rules [7], for purposes of dealing with the SNMP protocol. 4.1. Format of Definitions Section 6 contains the specification of all object types defined in this MIB module. The object types are defined using the conventions defined in the SMI, as amended by the extensions specified in "Towards Concise MIB Definitions" [4]. D. Throop [Page 4] Internet Draft X.25 Packet Layer MIB February 1992 5. Overview 5.1. Informal Overview This section describes how the objects defined below relate with other MIBs. This section is only informational to help understand how the pieces fit together. The objects defined below are used in conjunction with MIB-II and other MIBs such as the LAPB MIB [9]. A system with a complete X.25 stack running over a synchronous line will have at least two interfaces in the ifTable defined in MIB-II. There will be an interface for LAPB and another interface for the packet layer of X.25. There will also be objects defined in the RS-232-like MIB for the physical sync line. Each software interface identifies the layer below it used to send and receive packets. The X.25 MIB object, defined below, x25PleDataLinkId, specifies an instance of lapbParamIndex for the LAPB interface under that X.25. The LAPB object, lapbParamPortId, identifies an instance of the rs232PortIndex for the the Sync line used by LAPB. For X.25 running over LAPB over Ethernet, the lapbParamPortId would identify the instance of ifIndex for the Ethernet interface. Each X.25 subnetwork will have separate entries in the ifTable. Thus a system with two X.25 lines would have two ifTable entries for the two X.25 packet layers and two other entries for the two LAPB interfaces. Each X.25 Packet Layer MIB would identify the instance of the LAPB MIB for the interface below it. Each LAPB MIB would identify the Sync line below it. The system would also have two entries for rs232PortTable and rs232SyncPortTable for the two physical lines. Since the ifTable as defined in MIB-II is device independent, it doesn't have anything specific for any type of interface. The objects below define the X.25 packet layer specific information for an interface of type X.25. Different X.25 interfaces can also be differentiated by matching the values of ifIndex with x25PleIndex. D. Throop [Page 5] Internet Draft X.25 Packet Layer MIB February 1992 5.2. Textual Conventions This MIB introduces a new data type as a textual convention for use with X.25. This textual convention enhances the readability of the specification and can ease comparison with other specifications if appropriate. It should be noted that the introduction of such textual conventions has no effect on either the syntax nor the semantics of any managed objects. These conventions are merely an artifact of the explanatory method used. Objects defined in terms of one of these methods are always encoded by means of the rules that define the primitive type. Hence, no changes to the SMI or the SNMP are necessary to accommodate these textual conventions which are adopted merely for the convenience of readers and writers in pursuit of the elusive goal of clear, concise, and unambiguous MIB documents. This MIB introduces the data type of: X25address 5.3. Structure of MIB Instances of the objects defined below represent attributes of an X.25 Packet Layer interface. At present these interfaces are identified by an ifType object in the Internet-standard MIB [5] of: ddn-x25(4), and rfc887-x25(5). For these interfaces, the value of the ifSpecific variable in the MIB-II [5] has the OBJECT IDENTIFIER value: x25 OBJECT IDENTIFIER ::= { To Be Assigned } The objects defined below are similar to those defined in a draft ISO document for X.25 management [11]. Some object definitions also reference the ISO specification for X.25 [10] to specify the section that will give the reader addition information relative to the object. Access to those documents maybe useful (but isn't essential) to understand the names and semantics of some objects. The similarity of these objects with the ISO objects minimizes the instrumentation required by those systems that support both OSI and TCP/IP management D. Throop [Page 6] Internet Draft X.25 Packet Layer MIB February 1992 protocols. Since the objects defined here are extensions to the Internet Standard MIB [2] and thus also an extension of the second version, MIB-II [5], the objects defined here explicitly do not duplicate objects defined in existing standards. In some instances clarification of how to apply those objects has been given. The relationship between an X.25 Packet Layer interface and an interface in the context of the Internet-standard MIB [5] is one-to-one. As such, the value of an ifIndex object instance can be directly used to identify corresponding instances of the objects defined below. D.
