1.	Introduction
This document defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community.  In particular, it describes objects that provide management system access to the ATM Forum's M4 (Network Element View) interface via SNMP.

This document specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions.

The SNMPv2 MIB module defined in this document, in conjunction with other MIB modules defined in other documents, meets the functional requirements of the ATM Forum's M4 interface, as defined in ATM Forum af-nm-0020.000, "M4 Interface Requirements and Logical MIB" [10].  This document includes an SNMPv2 conformance statement formally specifying the use of these other MIB modules.
1.1.	Objectives
•	This MIB is intended to meet the functional requirements of the M4 Network Element View Interface Requirements and Logical MIB [10].

•	It must, wherever possible, refer to existing standard MIBs (e.g., RFC 1695 [8]), rather than containing objects that are similar or identical those defined elsewhere.

•	To the extent that SNMP does not have the required facilities to support a particular requirement or function in [10], that lack will be explicitly noted.
1.2.	SNMP Network Management Framework
The SNMP Network Management Framework presently consists of three major components.  They are:

•	the SMI, described in RFC 1902 [1] - the mechanisms used for describing and naming objects for the purpose of management.

•	the MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects for the Internet suite of protocols.

•	the protocol, RFC 1157 [3] and/or RFC 1905 [4] - the protocol for accessing managed objects.

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

This document also makes use of the following additional components of the SNMPv2 Network Management Framework:

•	RFC 1903 [15] which defines textual conventions for the specification of managed objects,

•	RFC 1904 [6] which defines conformance statements for the specification of managed objects,

•	RFC 2233 [5] which defines extensions to MIB-II for use by all interface types,

•	RFC 1451 [13] which defines managed objects for use between SNMP managers, including threshold management. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB.

•	RFC 2037 [16] which defines managed objects used for managing multiple logical and physical entities managed by a single SNMP agent.

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 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 also refer to the object type.
1.3.	Related MIB Modules
This document also makes use of MIB modules from the following documents:

•	RFC 1695 [8] which defines managed objects for use with ATM,

•	RFC 1595 [9] which defines managed objects for use with SONET/SDH interfaces,

•	RFC 1407 [11] which defines managed objects for use with DS3 and E3 interfaces,

•	RFC 1406 [12] which defines managed objects for use with DS1 and E1 interfaces,

•	RFC 1514 [14] which defines managed objects for administering host systems, including actual time.
2.	Overview
The protocol-independent definition of the M4 interface does not map directly into SNMP.  This section summarizes the way in which some of the functions required for M4 have been implemented in SNMP.

Wherever possible, already existing MIB objects have been re-used, and new MIB objects and traps have been defined to resemble similar features in other MIB modules.
2.1.	ATM NE
The following attributes of the ATM NE object are already defined in other documents, location name in MIB-II (sysLocation), managed entity ID either in MIB-II (sysName) or as the agent's IP address or both, external time in the host resources MIB defined in RFC 1514 (hrSystemDate).  The M4 operational state is not relevant for the SNMP agent because the agent will not be reachable if it is out of service due to some fault.  Objects to model the vendor name, version, start-up time, and alarm severity assignment are defined in this document.

It should be noted that an SNMP agent is expected to model a timestamp as time-ticks, or hundredths of a second since the agent's startup time.  This document has conformed to the SNMP model in this case.  The start time attribute can be used to determine the real time associated with a specific timestamp value.

The other ATM NE attributes (vendor, version, start time, alarm severity profile index, and suppress all-zero counts) are defined in this document.
2.2.	Hardware and software
The Host Resources MIB defined in RFC 1514 includes three tables for the management of software: software, running software performance, and installed software.  The M4 SNMP interface requires the first and third of these tables.

A single hardware unit table provides management access for Equipment, Equipment Holder, and Plug-In Unit components.  A type field in each table entry identifies which type of component it represents, and additional columns contain type-specific attributes.  A separate table maintains containment relationships between hardware units.

Two additional tables associate hardware units with the software running and installed on them respectively.
2.3.	ATM interfaces
Management information relating to the physical medium itself is maintained by the appropriate medium-specific MIB.  The interface table entry representing a physical media interface already contains two of the attributes of the M4 Physical Path Termination Point object: physical path type (ifType) and framing format (a media-specific attribute).  The relation between a physical media interface and an ATM interface running over it is maintained by the ifStackTable defined in RFC 2233.

The physical path TP and TC adapter resides in the same interface table row as the ATM cell layer (UNI, B-ICI, or B- ISSI).  The ATM MIB defined in RFC 1695 defines some of the columns common to all ATM cell layer interfaces; this document extends the MIB as required for M4 management. Where appropriate, the interface table entry also includes the columns of the DS3 PLCP table defined in RFC 1695.

The M4 SNMP interface makes use of the MIB-II system and interface tables as described in RFC 1695.  This includes the columns ifType (atm(37)), ifAdminStatus, and ifOperStatus.  Note that the status variables refer to the entire interface, including the physical path termination point and TC adapter sub-layers.

MIB-II does not have any provision for creating and deleting entries from the interface table, nor does the ATM interface configuration table in RFC 1695 add this facility.  The creation of entries in this table shall be outside the scope of the M4 interface.  Such entries are comprised of the columns in the following tables: from this document, physical path termination point and TC adapter objects, from RFC 1695, atmInterfaceConfTable, atmInterfaceDs3PlcpTable, and atmInterfaceTCTable.  They also include at least one column from the ATM cell layer interface table defined in this document.

This means that an entry in the ATM layer interface table exists even when there is no UNI, etc., defined.  In this case the column atmfM4IfType has the value none(0).  The management system defines a UNI or other interface for the table entry by modifying this column. (The terminology in this situation is confusing, but the distinction should be kept in mind between rows in the interface table and ATM cell layer interfaces, which can be of type UNI, B-ICI, B-ISSI and which may or may not exist on any given row in the table.)
2.4.	Virtual paths and virtual connections
The ATM MIB defined in RFC 1695 supports most of M4's requirements for managing VPs and VCs (point-to-point, as well as multi-point) but needs some extensions.

The following discussion refers to VPs, but the same is true for management of VCs.

RFC 1695 defines the atmVplTable to maintain information regarding both VPL and VPC termination points.  The values of the administrative status and cross-connect identifier columns indicate whether or not the VPL TP has a VPC TP associated with it.  This document describes an extension to the VPL table (using the AUGMENTS mechanism of SNMPv2's SMI) used to indicate whether or not the TP is a segment endpoint.

Traffic descriptors and quality-of-service parameters are stored in a separate table.  Each entry in the VPL table includes two indexes into this table (one for each direction of traffic).  It should be noted that the values used for traffic descriptor types in the ILMI MIB are different from those used in RFC 1695; the latter will be used for M4.

Cross-connections are maintained by a third table, indexed by a unique value and by the cross-connect endpoints.  Multi-point cross-connections are represented by multiple entries in this table; entries comprising a single multi-point connection will have the same cross-connect index.  This document describes an extension to the cross-connect table required for support of the recovery type attribute (again using the AUGMENTS mechanism).

RFC 1695 outlines the procedure to be used in creating VPLs, cross-connections, and VPC termination points.

The above description applies to VCs, as well.

RFC 1695 does not provide a mechanism for the agent, rather than the management system, to select the VPI value for a VPL cross-connect, or the VCI value for a VCL cross-connect (as in requirement CM-8).  This is provided using two new tables that will supply appropriate next index values. These tables are optional, as not all SNMP agents will be able to perform this function.
2.5.	Statistics
RFC 1407, dated January 1993, defines statistics for DS3/E3 interfaces but appears to make use of earlier versions of documents than those referenced for the M4 interface (which specifies ANSI T1.231-1993 and ANSI T1.pmnew).  RFC 1407 should be updated to take account of any changes since its last release; the M4 MIB will incorporate it by reference.

RFC 1595, dated March 1994, defines statistics for SONET/SDH interfaces but does not make use of G.774-01 (January 1994), which is specified for the M4 interface.  (It does make use of the January 1993 version of ANSI T1.231.)  RFC 1595 should be updated to take account of any changes since its last release; the M4 MIB will incorporate it by reference.

The current and historical fifteen-minute interval statistics to be maintained for ATM Cell Level Protocol Monitoring, TC Adapter Protocol Monitoring, and UPC/NPC Disagreement Monitoring are defined in this document. (RFC 1695 uses a column in the standard ifTable for one of the ATM cell statistics, but it stores a count since the agent was started, not since the beginning of the current interval.)  The historical statistics tables follow the pattern used for such statistics in the DS1, DS3, and SONET/SDH MIBs.  Because VPL and VPC termination points are indexed differently, UPC/NPC statistics for each of these object types are in a different table.
2.6.	Thresholds
Thresholds for ATM interfaces, as well as for VPL and VCL termination points, should be managed and reported using the standard threshold facilities defined for SNMPv2.  These are described in the manager-to-manager MIB, RFC 1451.  These facilities are adequate for ATM Cell Level Protocol Monitoring, measured at the interface level, as well as UPC/NPC Disagreement Monitoring, measured at VPL and VPC endpoints.
2.7.	Diagnostics
This document defines two tables similar to the ifTestTable defined in RFC 1573 [17], for the purpose of starting diagnostic tests on VP and VC endpoints, to be used for the OAM Loopback test.

It should be noted that RFC 1573 requires that the manager query the agent in order to discover the results of the test.  An SNMP agent cannot return test results in the response to the SNMP set-request that initiated the test because the test will likely take longer to complete than an SNMP management system can wait for a set-result; and if the agent were to emit a trap containing the test results, the inherent unreliability of the transport service means that the management system might never receive it.  Also note that ifTestTable was later deprecated in RFC 2233.
2.8.	Traps
The CMIP version of the M4 interface is able to make use of the standard trap logging and forwarding facilities. Equivalents of these for SNMP do not exist.  This document defines such facilities where required for the M4 functional requirements.  These should be considered provisional, until similar functions are standardized for the use of all SNMP agents.

Rather than defining generic trap types for the CMIP-style events corresponding to object creation, fault alarm, and so on, this document defines these events with a separate trap for each object type that can generate them.  In the case of alarms, each combination of alarm category, generic trouble (i.e., probable cause), and object type corresponds to a different trap type.  (As specified in the M4 Interface Requirements [10], most alarms can be generated by only one or two types of objects.)  This conforms to the procedure followed by other SNMP MIB modules.  It also allows an M4 SNMP agent to be used with applications that make decisions based on trap ID, particularly generic SNMP management applications, but also some MIB modules.

The trap forwarding configuration table allows traps to be discriminated on trap type, generating object, and alarm severity (when appropriate).  This MIB table is intended to be implemented at a trap logging element manager, rather than at each individual network element: at any given SNMP agent there can be one log for every combination of ATM NE and log type (creation, deletion, state change, configuration change, and alarm).  However, the MIB does not preclude logging at the individual ATM network element if desired.

Many SNMP agents will be unable to include event logging capabilities.  For this reason, conformance to the trap log portions of the MIB module is defined separately from conformance to the other M4 functions, in the expectation that the former functions are most likely to reside in an element manager, rather than in the ATM network element itself.
2.9.	Conformance statements
This document includes SNMPv2 SMI conformance statements specifying the required and optional features of the M4 interface.  They cover the MIBs defined specifically for M4, as well as the required elements of other MIBs, defined elsewhere.

          of the subject identifier:

          When the value noTest is written to this object, no

          case the test is aborted.  Writing any other value to
          this object is only valid when no test is currently in
          progress, in which case the indicated test is
          initiated.

          When read, this object always returns the most recent
          value that atmfM4VcTestType was set to.  If it has not been
          set since the last initialization of the network

* Much of the data required for the various log objects is supported through the notifications specified in the MIBs.  It is assumed that the log objects can be supported through a combination of the standard features of the typical SNMP managers and the atmfM4LoggedTrapTable.

The table atmfM4LoggedTrapTable will show what trap types have occurred for each type of log object. It is expected that the SNMP manager trap log will then be used to look at the details of the traps.
