- 1. Introduction
-
- This memo defines a portion of the Management Information Base (MIB)
- for use with network management protocols in the Internet community.
- In particular, it describes managed objects used for controlling the
- collection and storage of accounting information for connection-
- oriented networks such as ATM. The accounting data is collected into
- files for later retrieval via a file transfer protocol. For
- information on data which can be collected for ATM networks, see
- [19].
-
- 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.
-
- 3. Overview
-
- In some connection-oriented network environments, there is a need for
- the network administrator to be able to collect accounting data on
- the usage of bandwidth/resources by connections (e.g., ATM
- connections) within the network. Data collection should be available
- for switched virtual connections (SVCs and SVPs), and permanent
- virtual connections (PVCs and PVPs), including soft-permanent virtual
- connections (SPVCCs and SPVPCs). This need exists for ATM networks,
- and may well exist for other connection-oriented networks, such as
- Frame Relay.
-
- The potential quantity of such accounting information is such that it
- is not, in general, feasible to retrieve the information via SNMP. A
- better method is to store the collected accounting information in a
- file which can be subsequently retrieved via a file transfer
- protocol.
-
- It is, however, appropriate to provide management control of the
- selection and collection of such accounting data via SNMP. This memo
- describes a MIB module which provides such control in a manner
- independent of the type of network. One or more other documents
- provide definitions of particular items of accounting data which can
- be selected; for example, a particular set of data items which can be
- collected for ATM networks is specified in [19].
-
- 3.1. Operational Model
-
- The requirement is for switches (e.g., ATM switches) to collect data
- concerning the connections which are routed across some subset of
- their interfaces (e.g., ATM UNI and/or NNI interfaces). The
- collected data is stored into one or more "files". The use of
- multiple files allows, for example, the data collected for PVCs to be
- different from that collected for SVCs.
-
- In order to retrieve the data currently being stored in a file, the
- administrator instructs the switch to terminate the collection of
- data into that file, and start collecting data into a new file.
-
-
-
- McCloghrie, et. al. Standards Track [Page 3]
-
- RFC 2513 Connection-Oriented Accounting MIB February 1999
-
-
- After this operation, the data in the old file is available for
- retrieval via file transfer.
-
- A collection file is defined to have a maximum size. When the size
- of the file currently being collected exceeds a threshold percentage
- of that maximum size, an SNMP notification (e.g., a trap) can be
- optionally generated. An SNMP notification might also be generated
- if the file reaches its maximum size.
-
- The accounting data collected for each connection consists of a set
- of objects and their values. The set of objects and their values are
- collected on one or more of the following occasions:
-
- (1) on the release (termination) of a connection optionally
- including failed connection attempts;
-
- (2) for each active connection (having a particular minimum age) on
- a periodic basis;
-
- (3) for each active connection (having a particular minimum age)
- when so commanded by a management application.
-
- While collecting data to be stored in a particular file, the same set
- of objects is collected for each connection on each occasion. Having
- the same set of objects stored on each occasion allows the
- optimization of storing only the values of those objects. This
- results in a significantly smaller file size, since it allows the
- names of the objects to be stored once and only once at the beginning
- of the file, rather than having to store every value as a (name,
- value) pair.
-
- Two modes of agent behaviour are allowed on the event of a file
- reaching its maximum size:
-
- (1) management application in control:
-
- The agent does not automatically swap to a new file; rather, it
- discards newly collected data until the management application
- subsequently instructs it to swap to a new file. Before
- swapping to a new file, the name of the file into which data is
- currently being collected is an implementation issue of no
- concern to an NM application; after swapping to a new file, the
- name of the file available for retrieval is as specified by the
- controlling MIB objects. This behaviour allows the application
- to know exactly how many files need to be retrieved and their
- names without having to perform any type of file directory
- operation, but also results in the possibility that data will be
- discarded if the application does not instruct the agent to swap
-
-
-
- McCloghrie, et. al. Standards Track [Page 4]
-
- RFC 2513 Connection-Oriented Accounting MIB February 1999
-
-
- within the required time frame.
-
- (2) agent automatically swaps to new file:
-
- The agent terminates collection into the current (full) file,
- and begins collecting data into a new version of the same base
- file name. This behaviour aims to avoid loss of data by
- assuming that additional storage space is actually available to
- create a new version of the file. To support this behaviour,
- files are named using suffixes, such that when the current
- version of the file becomes full, the agent begins collecting
- data into a file with the same base file-name but with an
- incremented (or otherwise modified) suffix. This requires the
- application to perform file directory operations prior to
- retrieving completed files in order to know how many and which
- suffixes have been used.
-
- With either behaviour, any completed file must be an integral number
- of connection records (see below). When a file reaches its maximum
- size, collection into that file is terminated either immediately
- before or immediately after storing the whole of the current
- connection record into the file. The former causes the file to be
- just less than its maximum size, and the latter causes the file to be
- just greater than its maximum size.
-
- 3.2. Selection of Accounting Data
-
- 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 an 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.
-
- The rationale for defining each subset as a (subtree,list) tuple is
- that one and only one OBJECT IDENTIFIER and one OCTET STRING is
- needed to define the subset of objects. This simplifies the MIB
- mechanisms needed for selection: an NM application needs to create
- only one conceptual row in a MIB table for each subset (rather than
- needing to create a conceptual row in a table for each and every
-
-
-
- McCloghrie, et. al. Standards Track [Page 5]
-
- RFC 2513 Connection-Oriented Accounting MIB February 1999
-
-
- object in the set).
-
- The number of tuples supported by a particular switch is an
- implementation choice. One possibility is to support two (subtree,
- list) tuples so that one such tuple can specify a standard 'subtree'
- (e.g., the atmAcctngDataObjects subtree defined in [19]), and the
- second tuple can specify an enterprise-specific 'subtree'; this would
- allow the selected set of objects to be the union of a set of
- standard objects and a set of enterprise-defined objects.
-
- 3.3. Format of Collection File
-
- A collection file generated by this process contains the values of
- MIB objects defined using the SMIv2. The standard way to encode the
- values of SNMP MIB objects in a device-independent manner is through
- the use of ASN.1's Basic Encoding Rules (BER) [18]. Thus, the
- standard format of an accounting file is defined here using the same
- adapted subset of ASN.1 [17] as the SMIv2.
-
- The file consists of a set of header information followed by a
- sequence of zero or more collection records. The header information
- identifies (via sysName [16]) the switch which collected the data,
- the date and time at which the collection in to this file started,
- and the sequence of one or more (subtree, list) tuples identifying
- the objects whose values are contained in each connection record.
- The header information also includes a textual description of the
- data contained in the file.
-
- Each connection record contains a sequence of values for each
- identified tuple, in the same order as the tuples are identified in
- the header information. For each tuple, the sequence of values are
- in ascending order of the sub-identifier which identifies them within
- the subtree.
-
- Formally, an accounting file is an ASN.1 value with the following
- syntax:
-
- File ::=
- [1]
- IMPLICIT SEQUENCE {
- -- header information
- sysName -- name of the switch
- DisplayString,
-
- description -- textual description of the collection
- DisplayString,
-
- startTime -- start time of the collection
-
-
-
- McCloghrie, et. al. Standards Track [Page 6]
-
- RFC 2513 Connection-Oriented Accounting MIB February 1999
-
-
- DateAndTime,
-
- SEQUENCE OF { -- sequence of (subtree, list) tuples
- SEQUENCE {
- subtree
- OBJECT IDENTIFIER,
- list
- OCTET STRING
- }
- }
- -- sequence of connection records
- SEQUENCE OF {
- -- each record containing a sequence
- SEQUENCE OF { -- per identified tuple
-
- SEQUENCE OF { -- each per-tuple sequence containing
- value -- a sequence of object values
- ObjectSyntax
- }
- }
- }
- }
-
- where:
-
- (1) the value of the sysName component is that of the sysName object
- in the System group [16].
-
- (2) each (subtree, list) specifies the set of objects contained in
- that tuple's sequence within each and every connection record.
-
- (3) the tuples' sequences within each connection record occur in the
- same order as the (subtree, list) tuples occur in the header
- information.
-
- (4) the object values within each connection record occur in the
- same order as they are represented by the bits in the
- corresponding list value.
-
- (5) ObjectSyntax is defined by the SMIv2 [5].
-
- (6) One particular category of object values deserves special
- attention: an object defined to hold the checksum value of an
- accounting record (e.g., atmAcctngRecordCrc16, defined in [19]).
- An object in this category will generally have a SYNTAX of a
- fixed-length OCTET STRING, and have its value initialized to the
- string of all zeros when composing the accounting record
- containing it, with the location of these zeros being saved.
-
-
-
- McCloghrie, et. al. Standards Track [Page 7]
-
- RFC 2513 Connection-Oriented Accounting MIB February 1999
-
-
- Once the record is generated, the checksum is calculated over
- the whole connection record (including the starting SEQUENCE OF
- and the trailing end-of-contents octets, if used), and then the
- zeros are overwritten (at the saved location) by the calculated
- value of the checksum.
-
- The encoding of the above syntax using the Basic Encoding Rules is
- the same as defined by the SNMPv2 [10], with the following exception:
-
- - when encoding the length field for a structured type, i.e., a
- SEQUENCE or SEQUENCE OF, the indefinite form encoding is
- permitted.
-
- For example, the file containing the data:
-
- [1] IMPLICIT SEQUENCE a1 80
- OCTET STRING 04 09 73 77 69 74 63 68 2d 31 32
- OCTET STRING 04 0a 41 63 63 6f 75 6e 74 69 6e 67
- OCTET STRING 04 08 07 cc 07 14 10 05 00 00
- SEQUENCE OF 30 0e
- SEQUENCE 30 0c
- OBJECT IDENTIFIER 06 07 2b 06 01 03 7f 01 01
- OCTET STRING 04 01 c0
- SEQUENCE OF 30 80
- SEQUENCE OF 30 08
- SEQUENCE OF 30 06
- INTEGER 02 01 00
- INTEGER 02 01 21
- SEQUENCE OF 30 08
- SEQUENCE OF 30 06
- INTEGER 02 01 00
- INTEGER 02 01 22
- end-of-contents 00 00
- end-of-contents 00 00
-
- contains two connection records, each containing one tuple listing
- two (integer) data items in a (fictitious) subtree:
- 1.3.6.1.3.127.1.1. Its header indicates it's for "switch-12", with
- description "Accounting", and was collected at 16:05:00 on 20 July
- 1996.
-
- As well as the standard format defined above, the MIB allows other
- enterprise-specific formats to be used.

- The subtree specifies a single OBJECT IDENTIFIER value such
- that each object in the set is named by the subtree value
- appended with a single additional sub-identifier. The list
- specifies a set of data items, where the presence of an item
- in the list indicates that the item is (to be) present in

- from the list indicates that the item is not (to be) present
- in the data collected for a connection. Each data item is
- represented by an integer which when appended (as as

-
- The list is specified as an OCTET STRING in which each data
- item is represented by a single bit, where data items 1
- through 8 are represented by the bits in the first octet,
- data items 9 through 16 by the bits in the second octet,
- etc. In each octet, the lowest numbered data item is
- represented by the most significant bit, and the highest
- numbered data item by the least significant bit. A data
- item is present in the list when its bit is set, and absent
- when its bit is reset. If the length of an OCTET STRING
- value is too short to represent one or more data items

- 7. Security Considerations
-
- The MIB defined in this memo controls and monitors the collection of
- accounting data. Care should be taken to prohibit unauthorized
- access to this control capability in order to prevent the disruption
- of data collection, possibly with fraudulent intent. Example of such
- disruption are disabling the collection of data, or causing the wrong
- set of data items to be collected.
-
- SNMPv1 by itself is not a secure environment. Even if the network
- itself is secure (for example by using IPSec), even then, there is no
- control as to who on the secure network is allowed to access and
- GET/SET (read/change/create/delete) the objects in this MIB.
-
- It is recommended that the implementers consider the security
- features as provided by the SNMPv3 framework. Specifically, the use
- of the User-based Security Model RFC 2274 [12] and the View-based
- Access Control Model RFC 2275 [15] is recommended.
-
- It is then a customer/user responsibility to ensure that the SNMP
- entity giving access to an instance of this MIB, is properly
- configured to give access to the objects only to those principals
- (users) that have legitimate rights to indeed GET or SET
- (change/create/delete) them.
-
- 8. IANA Considerations
-
- Prior to publication of this memo as an RFC, IANA is requested to
- make a suitable OBJECT IDENTIFIER assignment.
