A table of control records for reports on the top `N' interfaces for the value or rate of a selected object. The number of entries depends on the configuration of the agent. The maximum number of entries is implementation dependent.

A set of parameters that control the creation of a report of the top N ports according to several metrics.

An index that uniquely identifies an entry in the interfaceTopNControl table. Each such entry defines one top N report prepared for a probe.

The particular variable to be sampled. Values between 1 and 23, point to MIB objects defined in IF-MIB [20]. Values between 24 and 36, point to MIB objects defined in EtherLike-MIB [23]. Values between 37 and 54, point to MIB objects defined in TOKENRING-MIB [24]. Values between 55 and 71, point to MIB objects defined in RMON-MIB [17]. Values between 72 and 74, point to MIB objects defined in BRIDGE-MIB [25]. Because SNMP access control is articulated entirely in terms of the contents of MIB views, no access control mechanism exists that can restrict the value of this object to identify only those objects that exist in a particular MIB view. Because there is thus no acceptable means of restricting the read access that could be obtained through the TopN mechanism, the probe must only grant write access to this object in those views that have read access to all objects on the probe. During a set operation, if the supplied variable name is not available in the selected MIB view, or does not conform the other conditions mentioned above, a badValue error must be returned. This object may not be modified if the associated interfaceTopNControlStatus object is equal to active(1). Enumeration: 'dot3StatsInternalMacTransmitErrors': 32, 'ifInMulticastPkts': 12, 'dot3StatsCarrierSenseErrors': 33, 'dot5StatsRemoves': 52, 'ifOutBroadcastPkts': 15, 'etherStatsPkts1024to1518Octets': 71, 'ifOutMulticastPkts': 14, 'dot5StatsTokenErrors': 45, 'dot3StatsFCSErrors': 25, 'dot3StatsSingleCollisionFrames': 26, 'etherStatsOversizePkts': 62, 'dot5StatsSignalLoss': 48, 'ifOutDiscards': 10, 'etherStatsJabbers': 64, 'dot5StatsReceiveCongestions': 43, 'dot5StatsTransmitBeacons': 49, 'etherStatsPkts256to511Octets': 69, 'dot1dTpPortInDiscards': 74, 'etherStatsCollisions': 65, 'dot5StatsAbortTransErrors': 40, 'dot3StatsAlignmentErrors': 24, 'etherStatsBroadcastPkts': 58, 'ifInDiscards': 4, 'dot5StatsACErrors': 39, 'ifInErrors': 5, 'etherStatsPkts512to1023Octets': 70, 'dot3StatsSymbolErrors': 36, 'dot5StatsBurstErrors': 38, 'dot1dTpPortOutFrames': 73, 'dot3StatsSQETestErrors': 28, 'ifHCInOctets': 16, 'dot3StatsDeferredTransmissions': 29, 'etherStatsMulticastPkts': 59, 'ifHCInBroadcastPkts': 19, 'ifHCInMulticastPkts': 18, 'etherStatsPkts65to127Octets': 67, 'dot3StatsLateCollisions': 30, 'etherStatsFragments': 63, 'ifHCInUcastPkts': 17, 'ifHCOutMulticastPkts': 22, 'dot5StatsHardErrors': 47, 'ifOutUcastPkts': 8, 'etherStatsPkts64Octets': 66, 'ifInOctets': 1, 'dot3StatsExcessiveCollisions': 31, 'etherStatsOctets': 56, 'ifInUcastPkts': 2, 'ifOutNUcastPkts': 9, 'dot5StatsLineErrors': 37, 'dot3StatsInternalMacReceiveErrors': 35, 'etherStatsPkts': 57, 'ifOutErrors': 11, 'dot5StatsLobeWires': 51, 'dot5StatsFrameCopiedErrors': 44, 'ifHCOutBroadcastPkts': 23, 'dot1dTpPortInFrames': 72, 'ifHCOutOctets': 20, 'ifInBroadcastPkts': 13, 'dot5StatsSoftErrors': 46, 'dot5StatsInternalErrors': 41, 'dot3StatsFrameTooLongs': 34, 'etherStatsPkts128to255Octets': 68, 'dot5StatsRecoverys': 50, 'etherStatsCRCAlignErrors': 60, 'dot5StatsSingles': 53, 'ifOutOctets': 7, 'dot5StatsLostFrameErrors': 42, 'ifInUnknownProtos': 6, 'etherStatsUndersizePkts': 61, 'etherStatsDropEvents': 55, 'ifHCOutUcastPkts': 21, 'dot5StatsFreqErrors': 54, 'ifInNUcastPkts': 3, 'dot3StatsMultipleCollisionFrames': 27.

The method of sampling the selected variable for storage in the interfaceTopNTable. If the value of this object is absoluteValue(1), the value of the selected variable will be copied directly into the topNValue. If the value of this object is deltaValue(2), the value of the selected variable at the last sample will be subtracted from the current value, and the difference will be stored in topNValue. If the value of this object is bandwidthPercentage(3), the agent records the total number of octets sent over an interval divided by the total number of octets that represent '100% bandwidth' for that interface. This ratio is multiplied by 1000 to retain a 3 digit integer (0..1000) in units of 'tenth of one percent'. This type of computation is accurate for the octet counters. The usage of this option with respect to packets or error counters is not recommended. This object may not be modified if the associated interfaceTopNControlStatus object is equal to active(1). Enumeration: 'bandwidthPercentage': 3, 'absoluteValue': 1, 'deltaValue': 2.

The method of normalization in computation of the selected value. If the value of this object is normalizationRequired(1), the value of the selected variable will be multiplied by a factor equal to the effective speed of the interface divided by the value of interfaceTopNNormalizationFactor. If the value of this object is normalizationNot Required(2), the value of the selected variable will be taken 'as is' in the TopN computation. This object may not be modified if the associated interfaceTopNControlStatus object is equal to active(1). Enumeration: 'normalizationRequired': 1, 'normalizationNotRequired': 2.

The value used for normalization if interfaceTopNNormalization has the value normalizationRequired(1).

The number of reports that have been generated by this entry.

The number of seconds left in the report currently being collected. When this object is modified by the management station, a new collection is started, possibly aborting a currently running report. The new value is used as the requested duration of this report, which is loaded into the associated interfaceTopNDuration object. When this object is set to a non-zero value, any associated interfaceTopNEntries shall be made inaccessible by the agent. While the value of this object is non-zero, it decrements by one per second until it reaches zero. During this time, all associated interfaceTopNEntries shall remain inaccessible. At the time that this object decrements to zero, the report is made accessible in the interfaceTopNTable. Thus, the interfaceTopN table needs to be created only at the end of the collection interval. If the value of this object is set to zero while the associated report is running, the running report is aborted and no associated interfaceTopNEntries are created.

The number of seconds that this report has collected during the last sampling interval, or if this report is currently being collected, the number of seconds that this report is being collected during this sampling interval. When the associated interfaceTopNTimeRemaining object is set, this object shall be set by the agent to the same value and shall not be modified until the next time the interfaceTopNTimeRemaining is set. This value shall be zero if no reports have been requested for this interfaceTopNControlEntry.

The maximum number of interfaces requested for the Top N Table. When this object is created or modified, the agent should set interfaceTopNGrantedSize as close to this object as is possible for the particular implementation and available resources.

The maximum number of interfaces in the top N table. When the associated interfaceTopNRequestedSize object is created or modified, the agent should set this object as closely to the requested value as is possible for the particular implementation and available resources. The agent must not lower this value except as a result of a set to the associated interfaceTopNRequestedSize object.

The value of sysUpTime when this top N report was last started. In other words, this is the time that the associated interfaceTopNTimeRemaining object was modified to start the requested report. If the report has not yet been started, the value of this object is zero.

The entity that configured this entry and is using the resources assigned to it.

The status of this row. If the value of this object is not equal to active(1), all associated entries in the interfaceTopNTable shall be deleted by the agent.

A table of reports for the top `N' ports based on setting of associated control table entries. The maximum number of entries depends on the number of entries in table interfaceTopNControlTable and the value of object interfaceTopNGrantedSize for each entry. For each entry in the interfaceTopNControlTable, interfaces with the highest value of interfaceTopNValue shall be placed in this table in decreasing order of that rate until there is no more room or until there are no more ports.

A set of statistics for an interface that is part of a top N report.

An index that uniquely identifies an entry in the interfaceTopN table among those in the same report. This index is between 1 and N, where N is the number of entries in this report. Increasing values of interfaceTopNIndex shall be assigned to entries with decreasing values of interfaceTopNValue until index N is assigned to the entry with the lowest value of interfaceTopNValue or there are no more interfaceTopNEntries. No ports are included in a report where their value of interfaceTopNValue would be zero.

This object identifies the index corresponding to the dataSource for this entry. For sorted values of variables belonging to the IF-MIB, EtherLike-MIB or TOKENRING-MIB, this value equals the ifIndex of the interface. For sorted values of variables belonging to the RMON-MIB, this value equals the interface corresponding to the data source, pointed to by the value of etherStatsDataSource. For sorted values of variables belonging to the BRIDGE-MIB, this value equals the interface corresponding to the bridge port, pointed to by the value of dot1dBasePortIfIndex.

The value at the end of the sampling interval, or the amount of change in the selected variable during this sampling interval for the identified interface. The selected variable is that interfaces's instance of the object selected by interfaceTopNObjectVariable. This value of this object will be computed for all cases when interfaceTopNObjectVariable points to a 32-bit counter or Gauge or when interfaceTopNObjectSampleType equals bandwidthPercentage(3), and will be zero for all other cases.

The value at the end of the sampling interval, or the amount of change in the selected variable during this sampling interval for the identified interface. The selected variable is that interfaces's instance of the object selected by interfaceTopNObjectVariable. This value of this object will be computed for all cases when interfaceTopNObjectVariable points to a 64-bit counter, and will be zero for all other cases.

Describes the requirements for conformance to the InterfaceTopN MIB.

A collection of objects providing interfaceTopN data for a multiple interfaces device.
