Category: ATM, Network Monitoring (RMON)

Description: Provides RMON-style remote monitoring objects for ATM network traffic analysis and cell-level statistics collection.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ATM-RMON-MIB?

ATM-RMON-MIB is an IETF standards-based MIB extending RMON (Remote Monitoring) concepts to ATM networks, enabling remote collection of cell-level and port-level traffic statistics. It exposes port selection group tables that define which ports/interfaces are aggregated for monitoring, along with descriptive metadata like creation time, owner, and status for each monitoring group. Its monitoring focus is on traffic/performance data collection configuration rather than hardware health - it lets an administrator set up and manage which ATM ports are being statistically monitored and by whom, forming the basis for broader ATM traffic analysis. It explicitly builds on the standard RMON MIB framework (RFC 2819) adapted for ATM interfaces. It is deployed in carrier and enterprise ATM networks where remote traffic monitoring probes are used to analyze cell-layer performance across multiple ports. Engineers implementing or auditing this functionality typically reference the ATM-RMON-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-RMON-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

ATM network probe/monitoring device
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

An administrator would create an entry in portSelGrpTable/portSelGrpEntry with a portSelGrpDescr and portSelGrpOwner, then associate individual ports via portSelTable/portSelEntry referencing portSelCollectGroup, and confirm portSelStatus/portSelGrpStatus shows the group as active. If a monitoring group's portSelGrpStatus reverts to an inactive state unexpectedly, it indicates the associated RMON probe or agent config was reset or failed, halting collection for that port group.

What Can Be Monitored

port selection group membership
monitoring group creation time and owner
monitoring group/status
collected group association per port

How to Use in IPNetwork Monitor

Example using atmStatsControlDropEvents OID:

Select an ATM network probes/monitoring device as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type atmStatsControlDropEvents into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of events in which cells which should have been counted in the associated atmStatsEntry, but were dropped by the probe due to lack of resources. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
atmConfig	1.3.6.1.4.1.9.10.16.1.5
atmConfigGroup	1.3.6.1.4.1.9.10.16.3.2.8			Configuration extentions used to control internal agent behavior.
atmHost	1.3.6.1.4.1.9.10.16.1.3
ATM atmHostAddress	1.3.6.1.4.1.9.10.16.1.3.2.1.1	AtmAddr	not-accessible	The ATM address for this atmHostEntry. This is represented as an octet string with specific semantics and length as identified by the AtmAddr textual convention. Note that only 20 octet 'AtmAddr' addresses are collected in this table.
ADR atmHostControlAddrCollectScope	1.3.6.1.4.1.9.10.16.1.3.1.1.5	AddressCollectScope	read-create	This object controls the granularity of address collection in atmHostTable entries created on behalf of this control entry, according to the rules specified by the AddressCollectScope textual convention. If the associated instance of atmHostControlStatus object is equal to active(1), this object may not be modified.
C32 atmHostControlDeletes	1.3.6.1.4.1.9.10.16.1.3.1.1.2	Counter32	read-only	The number of times an atmHost entry has been deleted from the atmHost table (for any reason). If an entry is deleted, then inserted, and then deleted, this counter will be incremented by 2. To allow for efficient implementation strategies, agents may delay updating this object for short periods of time. For example, an implementation strategy may allow internal data structures to differ from those visible via SNMP for short periods of time. This counter may reflect the internal data structures for those short periods of time. Note that the table size can be determined by subtracting atmHostControlDeletes from atmHostControlInserts.
C32 atmHostControlDropEvents	1.3.6.1.4.1.9.10.16.1.3.1.1.6	Counter32	read-only	The total number of events in which cells which should have been counted in the associated atmHostEntry, but were dropped by the probe due to lack of resources. Note that this number is not necessarily the number of cells or calls dropped; it is just the number of times this condition has been detected.
atmHostControlEntry	1.3.6.1.4.1.9.10.16.1.3.1.1		not-accessible	A conceptual row in the atmHostControlTable. Entries in this table are identified and indexed by the portSelGrpIndex object. At most one atmHost collection is done per portSelectGroup. An example of the indexing of this entry is atmHostControlInserts.1
C32 atmHostControlInserts	1.3.6.1.4.1.9.10.16.1.3.1.1.1	Counter32	read-only	The number of times an atmHost entry has been inserted into the atmHost table. If an entry is inserted, then deleted, and then inserted, this counter will be incremented by 2. To allow for efficient implementation strategies, agents may delay updating this object for short periods of time. For example, an implementation strategy may allow internal data structures to differ from those visible via SNMP for short periods of time. This counter may reflect the internal data structures for those short periods of time. Note that the table size can be determined by subtracting atmHostControlDeletes from atmHostControlInserts.
I32 atmHostControlMaxDesiredEntries	1.3.6.1.4.1.9.10.16.1.3.1.1.3	Integer32	read-create	The maximum number of entries that are desired in the atmHostTable on behalf of this control entry. The probe will not create more than this number of associated entries in the table, but may choose to create fewer entries in this table for any reason including the lack of resources. If this value is set to -1, the probe may create any number of entries in this table. If the associated instance of atmHostControlStatus object is equal to active(1), this object may not be modified.
STR atmHostControlOwner	1.3.6.1.4.1.9.10.16.1.3.1.1.7	OwnerString	read-create	The entity that configured this entry and is therefore using the resources assigned to it.
RES atmHostControlPriority	1.3.6.1.4.1.9.10.16.1.3.1.1.4	ResourcePriority	read-create	The priority this collection should be given to retain resources, in the event the probe must reclaim some resources in order to add new entries to an existing atmHost collection or add new collections of other types. If the associated instance of atmHostControlStatus object is equal to active(1), this object may not be modified.
ROW atmHostControlStatus	1.3.6.1.4.1.9.10.16.1.3.1.1.8	RowStatus	read-create	The status of this atmHostControlEntry. An entry may not exist in the active state unless all objects in the entry have an appropriate value. Specifically, appropriate values for the associated instances of atmHostControlMaxDesiredEntries, atmHostControlPriority, and atmHostControlAddrCollectScope must be set before this object may be set to active(1). This control entry may be created and destroyed independently of the associated portSelGrpEntry, however its associated atmHostTable can exist only when the portSelGrpEntry controlling this collection is active. If this object is not equal to active(1), all associated entries in the atmHostTable shall be deleted.
atmHostControlTable	1.3.6.1.4.1.9.10.16.1.3.1		not-accessible	A list of ATM host table control entries. These entries will enable the collection of ATM host information in the atmHostTable. Entries in the atmHostTable will be created on behalf of each entry in this table. A probe is required to support at most one atmHost collection per instance of an associated portSelectGroup, therefore the table is indexed by the portSelGrpIndex.
LAS atmHostCreateTime	1.3.6.1.4.1.9.10.16.1.3.2.1.3	LastCreateTime	read-only	The value of sysUpTime when this entry was activated. This can be used by the management station to ensure that the entry has not been deleted and recreated between polls.
atmHostEntry	1.3.6.1.4.1.9.10.16.1.3.2.1		not-accessible	A conceptual row in the atmHostTable. The portSelGrpIndex value in the index identifies the portSelectGroup on whose behalf this entry was created. An example of the indexing of this entry is atmHostInCells.4.20..2

Note that this value includes calls that are currently in progress. A probe should increment this counter each time a connection attempt is detected in which this ATM host is identified as the Calling Party. Note that for point-to-multipoint ATM connections, this counter is incremented only once per call, regardless of the number of leafs established at setup time or the number of leaf-initiated-join attempts since the call was established.
NUM atmHostOutNumCalls	1.3.6.1.4.1.9.10.16.1.3.2.1.13	ZeroBasedCounter32	read-only	The number of successfully established calls detected on ATM connections associated with this entry, in which the associated endpoint address was identified as the Calling Party address. Note that this value includes calls that are currently in progress. A probe should increment this counter each time a connection is successfully established in which this ATM host is identified as the Calling Party address.

The probe will add to this table all addresses seen as the source or destination address in all calls, on all ports configured in the portSelGrpEntry controlling this collection.
atmMatrix	1.3.6.1.4.1.9.10.16.1.4
ADR atmMatrixControlAddrCollectScope	1.3.6.1.4.1.9.10.16.1.4.1.1.5	AddressCollectScope	read-create	This object controls the granularity of address collection in atmMatrixSDTable and atmMatrixDSTable entries created on behalf of this control entry, according to the rules specified by the AddressCollectScope textual convention. If the associated instance of atmMatrixControlStatus object is equal to active(1), this object may not be modified.
C32 atmMatrixControlDeletes	1.3.6.1.4.1.9.10.16.1.4.1.1.2	Counter32	read-only	The number of times an atmMatrix entry has been deleted from the atmMatrix table (for any reason). If an entry is deleted, then inserted, and then deleted, this counter will be incremented by 2. The deletion of a conversation from both the atmMatrixSDTable and atmMatrixDSTable shall be counted as two deletions (even though every deletion from one table must be accompanied by a deletion from the other). To allow for efficient implementation strategies, agents may delay updating this object for short periods of time. For example, an implementation strategy may allow internal data structures to differ from those visible via SNMP for short periods of time. This counter may reflect the internal data structures for those short periods of time. Note that the table size can be determined by subtracting atmMatrixControlDeletes from atmMatrixControlInserts, and dividing the result by two.
C32 atmMatrixControlDropEvents	1.3.6.1.4.1.9.10.16.1.4.1.1.6	Counter32	read-only	The total number of events in which cells which should have been counted in the associated atmMatrixSDEntry and atmMatrixDSEntry, but were dropped by the probe due to lack of resources. Note that this number is not necessarily the number of cells or calls dropped; it is just the number of times this condition has been detected.

C32 atmMatrixControlInserts	1.3.6.1.4.1.9.10.16.1.4.1.1.1	Counter32	read-only	The number of times an atmMatrix entry has been inserted into the atmMatrix table. If an entry is inserted, then deleted, and then inserted, this counter will be incremented by 2. The addition of a conversation into both the atmMatrixSDTable and atmMatrixDSTable shall be counted as two insertions (even though every addition into one table must be accompanied by an insertion into the other). To allow for efficient implementation strategies, agents may delay updating this object for short periods of time. For example, an implementation strategy may allow internal data structures to differ from those visible via SNMP for short periods of time. This counter may reflect the internal data structures for those short periods of time. Note that the table size can be determined by subtracting atmMatrixControlDeletes from atmMatrixControlInserts, and dividing the result by two.

An entry may not exist in the active state unless all objects in the entry have an appropriate value. Specifically, the associated instances of atmMatrixControlMaxDesiredEntries, atmMatrixControlPriority, and atmMatrixControlAddrCollectScope objects must be set to appropriate values before this object may be set to active(1). This control entry may be created and destroyed independently of the associated portSelGrpEntry, however its associated atmMatrixSDTable and atmMatrixDSTable can exist only when the portSelGrpEntry controlling this collection is active. If this object is not equal to active(1), all associated entries in the atmMatrixSDTable and atmMatrixDSTable shall be deleted.

Further, this table will only contain entries that have a corresponding entry in the atmMatrixDSTable with the same source address and destination address.
I32 atmMatrixTopNControlDuration	1.3.6.1.4.1.9.10.16.1.4.4.1.6	Integer32	read-only	The number of seconds that this report has collected during the last sampling interval. When the associated atmMatrixTopNControlTimeRemaining object is set, this object shall be set by the probe to the same value and shall not be modified until the next time the atmMatrixTopNControlTimeRemaining is set. This value shall be zero if no reports have been requested for this atmMatrixTopNControlEntry.
atmMatrixTopNControlEntry	1.3.6.1.4.1.9.10.16.1.4.4.1		not-accessible	A conceptual row in the atmMatrixTopNControlTable. An example of the indexing of this table is atmMatrixTopNControlDuration.3.1
C32 atmMatrixTopNControlGeneratedReports	1.3.6.1.4.1.9.10.16.1.4.4.1.5	Counter32	read-only	The number of reports that have been generated by this entry.
I32 atmMatrixTopNControlGrantedSize	1.3.6.1.4.1.9.10.16.1.4.4.1.8	Integer32	read-only	The maximum number of host entries in this report. When the associated atmMatrixTopNControlRequestedSize object is created or modified, the probe should set this object as closely to the requested value as is possible for the particular implementation and available resources. The probe must not lower this value except as a result of a set to the associated atmMatrixTopNControlRequestedSize object. For example, if the value of atmMatrixTopNControlRateBase is equal to atmMatrixTopNCells(1), when the next topN report is generated, host entries with the highest value of atmMatrixSDCells shall be placed in this table in decreasing order of this rate until there is no more room or until there are no more matrix entries. Each atmMatrixSDCells value is copied to the associated atmMatrixTopNRate object. It is an implementation-specific matter how entries with the same value are sorted. It is also an implementation- specific matter as to whether or not zero-valued entries are available.
I32 atmMatrixTopNControlIndex	1.3.6.1.4.1.9.10.16.1.4.4.1.1	Integer32	not-accessible	An index that is used to uniquely identify an entry in the atmMatrixTopNControlTable. Each such entry defines one top N report prepared on behalf of one atmMatrix entry, which must exist before this entry may be created.
STR atmMatrixTopNControlOwner	1.3.6.1.4.1.9.10.16.1.4.4.1.10	OwnerString	read-create	The entity that configured this entry and is therefore using the resources assigned to it.
INT atmMatrixTopNControlRateBase	1.3.6.1.4.1.9.10.16.1.4.4.1.2	INTEGER	read-create	The variable for each atmMatrix entry that the atmMatrixTopNEntries are sorted by. This object may not be modified if the associated atmMatrixTopNControlStatus object is equal to active(1).
I32 atmMatrixTopNControlRequestedSize	1.3.6.1.4.1.9.10.16.1.4.4.1.7	Integer32	read-create	The maximum number of host entries requested for this report. When this object is created or modified, the probe should set atmMatrixTopNControlGrantedSize as closely to this object as is possible for the particular probe implementation and available resources.
SER atmMatrixTopNControlSClass	1.3.6.1.4.1.9.10.16.1.4.4.1.3	ServiceClass	read-create	The service class for which this topN control entry is collecting information in associated atmMatrixTopN reports. This object may not be modified if the associated atmMatrixTopNControlStatus object is equal to active(1).
TIM atmMatrixTopNControlStartTime	1.3.6.1.4.1.9.10.16.1.4.4.1.9	TimeStamp	read-only	The value of sysUpTime when this top N report was last started. In other words, this is the time that the associated atmMatrixTopNControlTimeRemaining object was modified to start the requested report or the time the report was last automatically (re)started. This object may be used by the management station to determine if a report was missed or not.
ROW atmMatrixTopNControlStatus	1.3.6.1.4.1.9.10.16.1.4.4.1.11	RowStatus	read-create	The status of this atmMatrixTopNControlEntry. An entry may not exist in the active state unless all objects in the entry have an appropriate value. If this object is not equal to active(1), all associated entries in the atmMatrixTopNTable shall be deleted by the agent.
atmMatrixTopNControlTable	1.3.6.1.4.1.9.10.16.1.4.4		not-accessible	A set of parameters that control the creation of a report of the top N matrix entries according to a selected metric.
I32 atmMatrixTopNControlTimeRemaining	1.3.6.1.4.1.9.10.16.1.4.4.1.4	Integer32	read-create	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, and is immediately loaded into the associated atmMatrixTopNControlDuration object. When the report finishes, the probe will automatically start another collection with the same initial value of atmMatrixTopNControlTimeRemaining. Thus the management station may simply read the resulting reports repeatedly, checking the startTime and duration each time to ensure that a report was not missed or that the report parameters were not changed. While the value of this object is non-zero, it decrements by one per second until it reaches zero. At the time that this object decrements to zero, the report is made accessible in the atmMatrixTopNTable, overwriting any report that may be there. When this object is modified by the management station, any associated entries in the atmMatrixTopNTable shall be deleted.
ATM atmMatrixTopNDstAddress	1.3.6.1.4.1.9.10.16.1.4.5.1.3	AtmAddr	read-only	The ATM endpoint address identified as the destination of the traffic measured in this report. Note that only 20 octet 'AtmAddr' addresses are collected in this table.
atmMatrixTopNEntry	1.3.6.1.4.1.9.10.16.1.4.5.1		not-accessible	A conceptual row in the atmMatrixTopNTable. The atmMatrixTopNControlIndex value in the index identifies the atmMatrixTopNControlEntry on whose behalf this entry was created. An example of the indexing of this table is atmMatrixTopNSrcAddress.1.3.10
I32 atmMatrixTopNIndex	1.3.6.1.4.1.9.10.16.1.4.5.1.1	Integer32	not-accessible	An index that uniquely identifies an entry in the atmMatrixTopNTable among those in the same report. This index is between 1 and N, where N is the number of entries in this report. Each conversation in the selected atmMatrixSDTable, for the report interval, is ranked in descending order of the metric identified by the atmMatrixTopNRate object. For example, if the value of atmMatrixTopNControlRateBase is equal to atmMatrixTopNCells(1), increasing values of atmMatrixTopNIndex shall be assigned to entries with decreasing delta values of atmMatrixSDCells (for the report interval), until index N is assigned or there are no more atmMatrixSDEntries.
I32 atmMatrixTopNRate	1.3.6.1.4.1.9.10.16.1.4.5.1.4	Integer32	read-only	The value of the ranked metric for this conversation, for this report. If the associated value of atmMatrixTopNRateBase is equal to atmMatrixTopNCells(1), then this object is assigned the delta value of the atmMatrixSDCells object during this report interval. If the associated value of atmMatrixTopNRateBase is equal to atmMatrixTopNNumCallAttempts(2), then this object is assigned the delta value of the atmMatrixSDNumCallAttempts object during this report interval. If the associated value of atmMatrixTopNRateBase is equal to atmMatrixTopNNumCalls(3), then this object is assigned the delta value of the atmMatrixSDNumCalls object during this report interval. If the associated value of atmMatrixTopNRateBase is equal to atmMatrixTopNConnTime(4), then this object is assigned the delta value of the atmMatrixSDConnTime object during this report interval.
I32 atmMatrixTopNReverseRate	1.3.6.1.4.1.9.10.16.1.4.5.1.5	Integer32	read-only	The value of the associated metric for this conversation, and for this report, but for the reverse direction. For example, if the associated value of atmMatrixTopNRateBase is equal to atmMatrixTopNCells(1), then this object contains the atmMatrixSDCells delta cell rate for the reverse direction traffic (i.e., destination to source traffic).
ATM atmMatrixTopNSrcAddress	1.3.6.1.4.1.9.10.16.1.4.5.1.2	AtmAddr	read-only	The ATM endpoint address identified as the source of the traffic measured in this report. Note that only 20 octet 'AtmAddr' addresses are collected in this table.
atmMatrixTopNTable	1.3.6.1.4.1.9.10.16.1.4.5		not-accessible	A set of statistics for those matrix entries that have counted the highest number of cells, calls, or connection time.
atmRmon	1.3.6.1.4.1.9.10.16			The MIB module for managing remote monitoring device implementations for ATM networks.
atmRmonConformance	1.3.6.1.4.1.9.10.16.3
INT atmRmonDataCollectMode	1.3.6.1.4.1.9.10.16.1.5.1	INTEGER	read-write	Controls the internal data collection for the entire ATM-RMON agent. If this object has a value of 'active(1)', then data tables will be created and maintained (normal behavior). If this object has a value of 'inactive(2)' then ATM-RMON monitoring will not occur, even if valid control tables exist for particular collections. Data tables for active collections are deleted when this object is changed to 'inactive(2)', but control tables are not deleted. When this object is changed to 'active(1)', data collection is started for all valid control tables.

CON atmStatsConnTime	1.3.6.1.4.1.9.10.16.1.2.2.1.8	ConnectTime	read-only	The elapsed time of all calls identified by the associated instance of the atmStatsNumCallAttempts object. Note that point-to-multipoint calls are counted only once, regardless of the number of leafs participating in the call.
C32 atmStatsControlDropEventsEx	1.3.6.1.4.1.9.10.16.1.2.1.1.1	Counter32	read-only	The total number of events in which cells which should have been counted in the associated atmStatsEntry, but were dropped by the probe due to lack of resources. Note that this number is not necessarily the number of cells or calls dropped; it is just the number of times this condition has been detected.
atmStatsControlEntry	1.3.6.1.4.1.9.10.16.1.2.1.1		not-accessible	A conceptual row in the atmStatsControlTable. Entries in this table are identified and indexed by the portSelGrpIndex object. At most one atmStats collection is done per portSelectGroup. An example of the indexing of this entry is atmStatsDropEvents.1 .
STR atmStatsControlOwner	1.3.6.1.4.1.9.10.16.1.2.1.1.2	OwnerString	read-create	The entity that configured this entry and is therefore using the resources assigned to it.
ROW atmStatsControlStatus	1.3.6.1.4.1.9.10.16.1.2.1.1.3	RowStatus	read-create	The status of this atmStatsControlEntry. This control entry may be created and destroyed independently of the associated portSelGrpEntry, however its associated atmStatsTable can exist only when the portSelGrpEntry controlling this collection is active. If this object is not equal to active(1), all associated entries in the atmStatsTable shall be deleted.
atmStatsControlTable	1.3.6.1.4.1.9.10.16.1.2.1		not-accessible	A list of ATM basic statistic collection table control entries. These entries will enable the collection of statistical totals for an entire portSelectGroup.
LAS atmStatsCreateTime	1.3.6.1.4.1.9.10.16.1.2.2.1.2	LastCreateTime	read-only	The value of sysUpTime when this entry was created. This can be used by the management station to ensure that the entry has not been deleted and recreated between polls.
atmStatsEntry	1.3.6.1.4.1.9.10.16.1.2.2.1		not-accessible	A conceptual row in the atmStatsTable. The portSelGrpIndex value in the index identifies the portSelectGroup on whose behalf this entry was created. An example of the indexing of this entry is atmStatsCells.8.1
atmStatsGroup	1.3.6.1.4.1.9.10.16.3.2.2			Counts the basic statistics for collections on behalf of particular portSelectGroup collections.
C64 atmStatsHCCells	1.3.6.1.4.1.9.10.16.1.2.2.1.5	Counter64	read-only	The high capacity version of the atmStatsCells object.
atmStatsHCGroup	1.3.6.1.4.1.9.10.16.3.2.3			Counts the high capacity basic statistics for collections on behalf of particular portSelectGroup collections. The atmStatsGroup must be implemented if the atmStatsHCGroup is implemented. This group is mandatory for implementations which support high capacity counters.
C32 atmStatsNumCallAttempts	1.3.6.1.4.1.9.10.16.1.2.2.1.6	Counter32	read-only	The number of call attempts detected on all signalled ATM connections on behalf of this portSelectGroup collection. A probe should increment this counter each time a connection setup attempt (identified with this portSelectGroup) is detected. For point-to-multipoint connections, this counter is incremented once per counted connection, regardless of the number of leafs identified in the connection.
C32 atmStatsNumCalls	1.3.6.1.4.1.9.10.16.1.2.2.1.7	Counter32	read-only	The number of successfully established calls detected on all signalled ATM connections on behalf of this portSelectGroup collection. Note that this value includes successfully established calls that are currently in progress. A probe should increment this counter each time a valid connection (identified with this portSelectGroup) is successfully established. For point-to-multipoint ATM connections, this counter is incremented once per counted connection, regardless of the number of leafs identified in the connection. Note that when a point-to-point connection setup enters on one port and leaves on another port in the same port select group, it is counted only once.
SER atmStatsSClass	1.3.6.1.4.1.9.10.16.1.2.2.1.1	ServiceClass	not-accessible	The quality of service classification for this entry. See the ServiceClass textual convention for details and specific class-of-service values.

portSelectGroup	1.3.6.1.4.1.9.10.16.3.2.1			Selects the ATM connections that should be monitored as part of a specific collection-group.
portSelEntry	1.3.6.1.4.1.9.10.16.1.1.2.1		not-accessible	A conceptual row in the portSelTable. Entries may only be created on behalf of ATM interfaces. That is, the ifType value associated with each ifIndex value must be equal to atm(37) or atmLogicalPort(80). An example of the indexing of this entry is portSelCreateTime.7 .
LAS portSelGrpCreateTime	1.3.6.1.4.1.9.10.16.1.1.1.1.3	LastCreateTime	read-only	The value of sysUpTime when this portSelGrp entry was activated. This can be used by the management station to ensure that the table has not been deleted and recreated between polls.
STR portSelGrpDescr	1.3.6.1.4.1.9.10.16.1.1.1.1.2	DisplayString	read-create	An administratively-assigned descriptive label for this portSelGrp entry.
portSelGrpEntry	1.3.6.1.4.1.9.10.16.1.1.1.1		not-accessible	A conceptual row in the portSelGrpTable. An example of the indexing of this entry is portSelGrpCreateTime.7 .
I32 portSelGrpIndex	1.3.6.1.4.1.9.10.16.1.1.1.1.1	Integer32	not-accessible	An arbitrary and unique index for this portSelGrpEntry. If portSelGrpTable entries are recreated by the agent after a restart, then the portSelGrpIndex value must be retained across a restart as well.
STR portSelGrpOwner	1.3.6.1.4.1.9.10.16.1.1.1.1.4	OwnerString	read-create	The entity that configured this entry and is therefore using the resources assigned to it.
ROW portSelGrpStatus	1.3.6.1.4.1.9.10.16.1.1.1.1.5	RowStatus	read-create	The status of this row. An entry may not exist in the active state unless all objects in the entry have an appropriate value. No objects are required to be written prior to the row being set to active(1). However, all portSelTable entries which are to be included in collections on behalf of this portSelectGroup, must be completely configured and activated before this object is set to active(1), since the associated instances of portSelStatus cannot be modified once this object has been set to active(1). If this object is not equal to active(1), all associated data collections shall be deleted (e.g., any associated collections in the atmStats, atmHostTable or atmMatrixSDTable). Note that associated portSelTable and any configured collection control entries (e.g., atmHostControlTable) are not deleted when this entry leaves the active state.
portSelGrpTable	1.3.6.1.4.1.9.10.16.1.1.1		not-accessible	Controls the setup of port and ATM connection selection criteria used on behalf of any collection associated with entries in this table (e.g., atmHostTable). This table allows portSelTable entries with the same value of the portSelCollectGroup object to be grouped together to form port select groups. Note that an agent implementation may restrict the actual number of portSelGrp entries, due to resource limitations.
STR portSelOwner	1.3.6.1.4.1.9.10.16.1.1.2.1.3	OwnerString	read-create	The entity that configured this entry and is therefore using the resources assigned to it.
ROW portSelStatus	1.3.6.1.4.1.9.10.16.1.1.2.1.4	RowStatus	read-create	The status of this row. An entry may not exist in the active state unless all objects in the entry have an appropriate value. Specifically, an appropriate value for the portSelCollectGroup object must be set before this object may be set to active(1). An agent may wish to allow portSelTable entries to exist which reference non-existent portSelGrpTable entries, in order to reduce row creation order dependencies. All portSelTable entries which are to be included in a particular collection (as indicated by the portSelCollectGroup object), should be completely configured and activated before the associated portSelGrpStatus object is set to active(1). Configuration of a portSelectGroup cannot be modified once collections on its behalf have been started. This object may not be modified if the associated portSelGroupStatus in in the active(1) state, indicated by a portSelGrpIndex value identical to the value of the portSelCollectGroup object in this entry.
portSelTable	1.3.6.1.4.1.9.10.16.1.1.2		not-accessible	Controls the setup of selection criteria for a single ATM port, used on behalf of any collections identified with the associated portSelectGroup (identified by its portSelGrpIndex value). This table identifies the collection characteristics for the ATM port indicated by the ifIndex value in the index. Note that an agent implementation may restrict the actual number of portSelTable entries, due to resource limitations.
