RFC 2513
RFC 2513 Connection-Oriented Accounting MIB February 1999 STATUS current DESCRIPTION "The current size of the file into which data is currently being collected, including header information." ::= { acctngFileEntry 7 } acctngFileFormat OBJECT-TYPE SYNTAX INTEGER { other(1), ber(2) } MAX-ACCESS read-create STATUS current DESCRIPTION "An indication of the format in which the accounting data is to be stored in the file. If the value is modified, the new value takes effect after the next 'swap' to a new file. The value ber(2) indicates the standard format." DEFVAL { ber } ::= { acctngFileEntry 8 } acctngFileCollectMode OBJECT-TYPE SYNTAX BITS { onRelease(0), periodically(1) } MAX-ACCESS read-create STATUS current DESCRIPTION "An indication of when accounting data is to be written into this file. Note that in addition to the occasions indicated by the value of this object, an agent always writes information on appropriate connections to the file when the corresponding instance of acctngFileCommand is set to 'collectNow'. - 'onRelease' - whenever a connection (or possibly, connection attempt) is terminated, either through a Release message or through management removal, information on that connection is written. - 'periodically' - information on appropriate connections is written on the expiry of a periodic timer, This value may be modified at any time." DEFVAL { { onRelease } } ::= { acctngFileEntry 9 } acctngFileCollectFailedAttempts OBJECT-TYPE SYNTAX BITS { soft(0), regular(1) } MAX-ACCESS read-create STATUS current DESCRIPTION "An indication of whether connection data is to be collected McCloghrie, et. al. Standards Track [Page 17] RFC 2513 Connection-Oriented Accounting MIB February 1999 for failed connection attempts when the value of the corresponding instance of acctngFileCollectMode includes 'onRelease'. The individual values have the following meaning: 'soft' - indicates that connection data is to be collected for failed Soft PVCs/PVPs which originate or terminate at the relevant interface. 'regular' - indicates that connection data is to be collected for failed SVCs, including Soft PVCs/PVPs not originating or terminating at the relevant interface. This value may be modified at any time." DEFVAL { { soft, regular } } ::= { acctngFileEntry 10 } acctngFileInterval OBJECT-TYPE SYNTAX Integer32 (60..86400) UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "The number of seconds between the periodic collections of accounting data when the value of the corresponding instance of acctngFileCollectMode includes 'periodically'. Some agents may impose restrictions on the range of this interval. This value may be modified at any time." DEFVAL { 3600 } ::= { acctngFileEntry 11 } acctngFileMinAge OBJECT-TYPE SYNTAX Integer32 (60..86400) UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "The minimum age of a connection, as used to determine the set of connections for which data is to be collected at the periodic intervals and/or when acctngFileCommand is set to 'collectNow'. The age of a connection is the elapsed time since it was last installed. When the periodic interval expires for a file or when acctngFileCommand is set to 'collectNow', accounting data is collected and stored in the file for each connection having a type matching acctngSelectionType and whose age at that time is greater than the value of acctngFileMinAge McCloghrie, et. al. Standards Track [Page 18] RFC 2513 Connection-Oriented Accounting MIB February 1999 associated with the file. This value may be modified at any time." DEFVAL { 3600 } ::= { acctngFileEntry 12 } acctngFileRowStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The status of this conceptual row. This object can not be set to 'active' until a value has been assigned to the corresponding instance of acctngFileName. Collection of data into the file does not begin until this object has the value 'active' and one or more (active) instances of acctngSelectionFile refer to it. If this value is modified after a collection has begun, collection into this file terminates and a new (or new version of the) file is immediately made ready for future collection (as if acctngFileCommand had been set to 'swapToNewFile'), but collection into the new (or new version of the) file does not begin until the value is subsequently set back to active." ::= { acctngFileEntry 13 } -- Overall Control acctngAdminStatus OBJECT-TYPE SYNTAX INTEGER { enabled(1), disabled(2) } MAX-ACCESS read-write STATUS current DESCRIPTION "A control object to indicate the administratively desired state of the collection of accounting records across all interfaces. Modifying the value of acctngAdminStatus to 'disabled' does not remove or change the current configuration as represented by the active rows in the acctngSelectionTable, acctngFileTable and acctngInterfaceTable tables." ::= { acctngInterfaceControl 1 } acctngOperStatus OBJECT-TYPE SYNTAX INTEGER { enabled(1), disabled(2) } MAX-ACCESS read-only STATUS current DESCRIPTION McCloghrie, et. al. Standards Track [Page 19] RFC 2513 Connection-Oriented Accounting MIB February 1999 "A status object to indicate the operational state of the collection of accounting records across all interfaces. When the value of acctngAdminStatus is modified to be 'enabled', the value of this object will change to 'enabled' providing it is possible to begin collecting accounting records. When the value of acctngAdminStatus is modified to be 'disabled', the value of this object will change to 'disabled' as soon as the collection of accounting records has terminated." ::= { acctngInterfaceControl 2 } acctngProtection OBJECT-TYPE SYNTAX TestAndIncr MAX-ACCESS read-write STATUS current DESCRIPTION "A control object to protect against duplication of control commands. Over some transport/network protocols, it is possible for SNMP messages to get duplicated. Such duplication, if it occurred at just the wrong time could cause serious disruption to the collection and retrieval of accounting data, e.g., if a SNMP message setting acctngFileCommand to 'swapToNewFile' were to be duplicated, a whole file of accounting data could be lost. To protect against such duplication, a management application should retrieve the value of this object, and include in the Set operation needing protection, a variable binding which sets this object to the retrieved value." ::= { acctngInterfaceControl 3 } acctngAgentMode OBJECT-TYPE SYNTAX INTEGER { swapOnCommand(1), swapOnFull(2) } MAX-ACCESS read-only STATUS current DESCRIPTION "An indication of the behaviour mode of the agent when a file becomes full: 'swapOnCommand' - the agent does not automatically swap to a new file; rather, it discards newly collected data until a management application subsequently instructs it to swap to a new file. 'swapOnFull' - the agent terminates collection into the McCloghrie, et. al. Standards Track [Page 20] RFC 2513 Connection-Oriented Accounting MIB February 1999 current file as and when that file becomes full." ::= { acctngInterfaceControl 4 } -- Per-interface control table acctngInterfaceTable OBJECT-TYPE SYNTAX SEQUENCE OF AcctngInterfaceEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A table controlling the collection of accounting data on specific interfaces of the switch." ::= { acctngInterfaceControl 5 } acctngInterfaceEntry OBJECT-TYPE SYNTAX AcctngInterfaceEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry which controls whether accounting data is to be collected on an interface. The types of interfaces which are represented in this table is implementation-specific." INDEX { ifIndex } ::= { acctngInterfaceTable 1 } AcctngInterfaceEntry ::= SEQUENCE { acctngInterfaceEnable TruthValue } acctngInterfaceEnable OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION "Indicates whether the collection of accounting data is enabled on this interface." ::= { acctngInterfaceEntry 1 } -- Objects for controlling the use of Notifications acctngControlTrapThreshold OBJECT-TYPE SYNTAX INTEGER (0..99) MAX-ACCESS read-write STATUS current DESCRIPTION "A percentage of the maximum file size at which a 'nearly- McCloghrie, et. al. Standards Track [Page 21] RFC 2513 Connection-Oriented Accounting MIB February 1999 full' trap is generated. The value of 0 indicates that no 'nearly-full' trap is to be generated." ::= { acctngTrapControl 1 } acctngControlTrapEnable OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION "An indication of whether the acctngFileNearlyFull and acctngFileFull traps are enabled." ::= { acctngTrapControl 2 } -- notifications acctngNotifications OBJECT IDENTIFIER ::= { accountingControlMIB 2 } acctngNotifyPrefix OBJECT IDENTIFIER ::= { acctngNotifications 0 } acctngFileNearlyFull NOTIFICATION-TYPE OBJECTS { acctngFileName, acctngFileMaximumSize, acctngControlTrapThreshold, acctngFileNameSuffix } STATUS current DESCRIPTION "An indication that the size of the file into which accounting information is currently being collected has exceeded the threshold percentage of its maximum file size. This notification is generated only at the time of the transition from not-exceeding to exceeding." ::= { acctngNotifyPrefix 1 } acctngFileFull NOTIFICATION-TYPE OBJECTS { acctngFileName, acctngFileMaximumSize, acctngFileNameSuffix } STATUS current DESCRIPTION "An indication that the size of the file into which accounting information is currently being collected has transistioned to its maximum file size. This notification is generated (for all values of acctngAgentMode) at the time of the transition from not-full to full. If acctngAgentMode has the value 'swapOnCommand', it is also generated periodically thereafter until such time as collection of McCloghrie, et. al. Standards Track [Page 22] RFC 2513 Connection-Oriented Accounting MIB February 1999 data is no longer inhibited by the file full condition." ::= { acctngNotifyPrefix 2 } -- conformance information acctngConformance OBJECT IDENTIFIER ::= { accountingControlMIB 3 } acctngGroups OBJECT IDENTIFIER ::= { acctngConformance 1 } acctngCompliances OBJECT IDENTIFIER ::= { acctngConformance 2 } acctngCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for switches which implement the Accounting Control MIB."

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. McCloghrie, et. al.
