1. 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.

RFC 2512 Accounting Information for ATM Networks February 1999
2. The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 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] and RFC 1215 [4].
The second version, called SMIv2, is described in RFC 1902 [5],
RFC 1903 [6] and RFC 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 in RFC 1901 [9] and
RFC 1906 [10]. The third version of the message protocol is
called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and
RFC 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 in RFC 1905
[13].
o A set of fundamental applications described in RFC 2273 [14] and
the view-based access control mechanism described in RFC 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 1999
3. 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.

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."

7. 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.
