Revision History June 26 1992 The June 29, 1992 release (Editor's Internal Reference Number 2.12) made the following changes: The range of x25ChannelLIC was changed from (0..4096) to (0..4095). The range of x25ChannelHIC was changed from (0..4096) to (0..4095). The range of x25ChannelLTC was changed from (0..4096) to (0..4095). The range of x25ChannelHTC was changed from (0..4096) to (0..4095). The range of x25ChannelLOC was changed from (0..4096) to (0..4095). The range of x25ChannelHOC was changed from (0..4096) to (0..4095). The range of x25CircuitChannel was changed from (1..4096) to (0..4095). The range of x25ClearedCircuitChannel was changed from (1..4096) to (0..4095). June 1992 The June 92 release (Editor's Internal Reference Number 2.11) made the following changes: A value of dxe was defined for x25AdmnInterfaceMode and x25OperInterfaceMode. The objects in the x25ChannelTable can now have a value of zero to indicate no channels configured in the range. The length of an X121Address was extended to 17 to accommodate the 1988 CCITT X.25 standard. D. Throop Invalid after Dec 31, 92 [Page 2] Internet Draft X.25 Packet Layer MIB June 1992 Some object descriptions have been expanded and simplified, these include: all the channel table objects except the index, x25AdmnDataRxmtCount, x25AdmnRejectCount, x25AdmnRegistrationRequestCount, x25OperDataRxmtCount, x25OperRejectCount, x25OperRegistrationRequestCount, x25CircuitEstablishTime, x25ClearedCircuitTimeEstablished, x25ClearedCircuitTimeCleared, x25CallParmIndex, x25CallParmInPacketSize, x25CircuitCalledAddress, x25CircuitOriginallCalledAddress, x25CircuitCallingAddress, x25CallParmFastSelect, x25CallParmCug, x25CallParmCugoa, x25CallParmBcug, x25CallParmNui, x25CallParmRpoa, x25CallParmCallingExt, x25CallParmCalledExt, x25CallParmProtection, x25StatInCallRefusals and x25CallParmOutPacketSize. The x25StatNumberPvcs object was deleted and x25AdmnNumberPVCs and x25OperNumberPVCs objects added. The object x25StatOutDataPackets was added. The object x25AdmnProtocolVersionSupported as added. The x25CircuitRemoteDteAddress was deleted. Some ASN.1 errors were corrected. April 1992 The April release (Editor's Internal Reference Number 2.8) made many changes to incorporate the comments of the working group meeting in March 1992. All reference comments were changed to reference fields. The type PositiveInteger was imported from the RFClapb- MIB and used for all index and timer values. The x25PleTable was split into the x25AdmnTable, x25OperTable, and x25StatTable. The timer and counter objects from the x25CircuitTable were moved to the x25AdmnTable and replicated in the x25OperTable D. Throop Invalid after Dec 31, 92 [Page 3] Internet Draft X.25 Packet Layer MIB June 1992 The objects in the x25CircuitTable were reordered to put the non-integer objects at the end of the table for easier implementation. The called and calling extension character set was extended to include a-f, and A-F. Additional states were added to the x25CircuitStatus object. Additional values were added to x25CircuitDirection x25CircuitCallParamId, and the addresses in the Circuit Table for PVCs. The length of the X25Address was changed to 0..15. The objects x25ClearedCircuitTimeEstablished, x25ClearedCircuitInPdus, and x25ClearedCircuitOutPdus were added to the x25ClearedCircuitTable. The name of the x25CircuitName was changed to x25CircuitDescr and the description was expanded. The access of the x25CircuitCallParamId was changed to read-only. The x25ClearedCircuitCodes object was split into the x25ClearedCircuitClearingCause and x25ClearedCircuitDiagnosticCode objects. The semantics of the x25ClearedCircuitIndex was redefined. Some of the description clauses were changed in an attempt to add clarity. DEFVAL clauses were added to most objects in the x25CallParmTable. Additional text was added to the description section to provide an overview of the tables of the MIB. The minimum allowable value for maximum active circuits was changed from one to zero. D. Throop Invalid after Dec 31, 92 [Page 4] Internet Draft X.25 Packet Layer MIB June 1992 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. 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 1991 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. D. Throop Invalid after Dec 31, 92 [Page 5] Internet Draft X.25 Packet Layer MIB June 1992 The name of the counter object x25TmrStatClearCountsExceeded was changed to x25TmrStatClearCountExceededs. All occurrence of Guage was changed to Gauge. Added the x25CallFcltyTable, x25CallFcltyCcittTable, and x25CallParamTable. 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 D. Throop Invalid after Dec 31, 92 [Page 6] Internet Draft X.25 Packet Layer MIB June 1992 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 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 Invalid after Dec 31, 92 [Page 7] Internet Draft X.25 Packet Layer MIB June 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, x25OperDataLinkId, specifies an instance of lapbAdmnIndex for the LAPB interface under that X.25. The LAPB object, lapbOperPortId, identifies an instance of the rs232PortIndex for the the Sync line used by LAPB. For X.25 running over LAPB over Ethernet, the lapbOperPortId 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 in the 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 x25AdmnIndex. D. Throop Invalid after Dec 31, 92 [Page 8] Internet Draft X.25 Packet Layer MIB June 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: X121Address 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-II [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 additional information about 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 Invalid after Dec 31, 92 [Page 9] Internet Draft X.25 Packet Layer MIB June 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. 5.4. Tables The objects below form several tables. These tables are: x25AdmnTable x25OperTable x25StatTable x25ChannelTable x25CircuitTable x25ClearedCircuitTable x25CallParmTable The x25AdmnTable defines objects for the parameters of an X.25 interface which the administrator can read and set. These objects are used at interface initialization time to start the interface. Once the interface has started, changes to the objects in the Administration table may not take affect until the interface is re-initialized. The x25OperTable defines objects that report the current parameters used by a running interface. These objects are read-only. The x25StatTable defines objects that report operational statistics for an X.25 interface. These are read-only counters of events that occurred at the interface. The x25ChannelTable defines objects to allow the administrator to manage the division of channel numbers. D. Throop Invalid after Dec 31, 92 [Page 10] Internet Draft X.25 Packet Layer MIB June 1992 The x25CircuitTable defines objects that return information about existing X.25 circuits. These entries result from calls placed or answered by the PLE or from PVCs. The x25ClearedCircuitTable contains objects for recording the termination information from circuits that cleared abnormally. The x25CallParmTable defines the call parameters used to call other systems. This table contains call parameter entries which are referenced by other tables. For example, the x25AdmnTable has one object that identifies the entry in the table for the default PLE parameters. The x25CircuitTable has one object that identifies the entry in the x25CallParmTable for the parameters in use by that circuit. Other MIBs may also reference entries to identify call parameters to use to make X.25 calls. 5.5. Table Usage Different tables provide different functions. The administrator sets the starting X.25 parameters in the x25AdmnTable for the X.25 PLE; these objects include a reference to the x25CallParmTable entry to identify the default call parameters for the PLE. Once all the parameters are set, the administrator initializes the interface. As part of initializing the interface, the operating parameters are copied into the interface from the x25AdmnTable; these parameters are viewable by getting the objects in the x25OperTable. (The interface maybe started by setting the value of ifAdminStatus to up.) If any PVCs are configured, their parameters can be set in the the x25CircuitTable before initializing the interface; this should be done in conjunction with configuring higher layer entities to use the PVCs via the MIBs for those entities. Once the PLE completes initialization, it makes additional entries in the x25circuitTable for calls placed or answered. When a circuit is cleared, the status of the entry for the circuit is set to closed and, if the clear is abnormal, an entry will also be made in the x25ClearedCircuitTable. An entry in the x25CircuitTable with a status of closed maybe deleted by the agent at its convenience. A closed entry will always be reused at the time the PLE re-allocates the channel number of the entry for another call. The call parameters used for a circuit can be found by looking in the D. Throop Invalid after Dec 31, 92 [Page 11] Internet Draft X.25 Packet Layer MIB June 1992 x25CircuitTable and following the x25CircuitCallParamId pointer to the entry in the x25CallParmTable that contains the parameters. There are no mechanisms in the X.25 MIB for telling the PLE to place an X.25 call. Such mechanisms belong in the MIBs for the higher layer entities that use the X.25 circuits. 5.6. Conformance All the objects defined here are mandatory. To claim conformance with this MIB an implementation must support all objects. However some objects pertain to features that are optional. There are values defined for those objects that indicate the implementation does not support the optional feature. The agent for such an implementation must support reading the object and return the value that indicates the optional feature isn't supported and reject set requests to change the object. Some optional features have more than one object that pertain to it (window rotation has a timer, a count, and a counter for timer runouts). In such case, any object which indicates the optional feature isn't supported is sufficient to indicate the feature isn't supported and the values of the other objects relative to that feature are undefined.

An instance with the value PVC can only be set to startPvcResetting or invalid and that action resets the PVC or deletes the circuit respectively.

A non-existing instance can be set to PVC to create a PVC if the implementation supports dynamic creation of PVCs. Some implementations may only allow creation and deletion of PVCs if the interface is down. Since the instance identifier will supply the PLE index and the channel number, setting this object alone supplies sufficient information to create the instance.

An entry in the closed or invalid state may be deleted or reused at the agent's convence. If the entry is kept in the closed state, the values of the parameters associated with the entry must be correct. Closed implies the values in the circuit table are correct. The value of invalid indicates the other values in the table are invalid. Many agents may never return a value of invalid because they dynamically allocate and free unused table entries.
