Introduction   This memo defines a portion of the Management Information Base (MIB)   for use with network management protocols in the Internet community.   A separate memo [16] defines managed objects, in a manner independent   of the type of network, for controlling the selection, collection and   storage of accounting information into files for later retrieval via   a file transfer protocol. This memo defines a set of ATM-specific   accounting information which can be collected for connections on ATM   networks.McCloghrie, et. al.         Standards Track                     [Page 1]

RFC 2512        Accounting Information for ATM Networks    February 19992.  The SNMP Network Management Framework   The SNMP Management Framework presently consists of five major   components:   o    An overall architecture, described inRFC 2271 [1].   o    Mechanisms for describing and naming objects and events for the        purpose of management.  The first version of this Structure of        Management Information (SMI) is called SMIv1 and described in        STD 16,RFC 1155 [2], STD 16,RFC 1212 [3] andRFC 1215 [4].        The second version, called SMIv2, is described inRFC 1902 [5],RFC 1903 [6] andRFC 1904 [7].   o    Message protocols for transferring management information.  The        first version of the SNMP message protocol is called SNMPv1 and        described in STD 15,RFC 1157 [8].  A second version of the SNMP        message protocol, which is not an Internet standards track        protocol, is called SNMPv2c and described inRFC 1901 [9] andRFC 1906 [10].  The third version of the message protocol is        called SNMPv3 and described inRFC 1906 [10],RFC 2272 [11] andRFC 2274 [12].   o    Protocol operations for accessing management information.  The        first set of protocol operations and associated PDU formats is        described in STD 15,RFC 1157 [8].  A second set of protocol        operations and associated PDU formats is described inRFC 1905        [13].   o    A set of fundamental applications described inRFC 2273 [14] and        the view-based access control mechanism described inRFC 2275        [15].   Managed objects are accessed via a virtual information store, termed   the Management Information Base or MIB.  Objects in the MIB are   defined using the mechanisms defined in the SMI.   This memo specifies a MIB module that is compliant to the SMIv2.  A   MIB conforming to the SMIv1 can be produced through the appropriate   translations.  The resulting translated MIB must be semantically   equivalent, except where objects or events are omitted because no   translation is possible (e.g., use of Counter64).  Some machine   readable information in SMIv2 will be converted into textual   descriptions in SMIv1 during the translation process.  However, this   loss of machine readable information is not considered to change the   semantics of the MIB.McCloghrie, et. al.         Standards Track                     [Page 2]

RFC 2512        Accounting Information for ATM Networks    February 19993.  Overview   In [16], the items of accounting data to be collected are specified   as a set of objects.  Which objects are contained in such a set is   selectable by an administrator through the specification of one or   more (subtree, list) tuples, where the set of objects to be collected   is the union of the subsets specified by each tuple:       'subtree' specifies a OBJECT IDENTIFIER value such that every           object in the subset is named by the subtree's value appended           with a single additional sub-identifier.       'list' specifies an OCTET STRING value, such that if the N-th bit           of the string's value is set then the the subset contains the           object named by appending N as a single additional sub-           identifier to the subtree.   This memo specifies such a subtree containing a set of objects   defining items of accounting information which are applicable to ATM   connections.   Note that all of the objects defined here have a MAX-ACCESS clause of   not-accessible, since their purpose is not to be read/written by   SNMP, but rather, to be the syntax and semantics of the set of   information which can be represented within a single (subtree, list)   tuple.4.

While the mechanism for calculating/encoding the checksum            value is specific to the method of encoding the accounting            record, an accounting record containing this object is            typically generated by initializing the value of this object            to the all-zeros string ('0000'H), with the location of            these zeros being saved.  After generating the record, the            checksum is calculated over the whole connection record and            then the all-zeros value is overwritten (at the saved            location) by the calculated value of the checksum."    ::= { atmAcctngDataObjects 33 }McCloghrie, et. al.

Security Considerations   This MIB module defines data items for potential use as accounting   information.  Each of these data items is only accessible through a   collected accounting file.  After being collected, the accounting   data should be protected against modification or unauthorized   deletion.8.  IANA Considerations   Prior to publication of this memo as an RFC, IANA is requested to   make a suitable OBJECT IDENTIFIER assignment.McCloghrie, et. al.
