What Is NMS-IF-THRESHOLD-MIB?
NMS-IF-THRESHOLD-MIB is a vendor MIB from NMS Communications that defines managed objects for monitoring configurable traffic thresholds on network interfaces, using reusable threshold templates that can be applied to any subset of interfaces on a network element. It exposes configuration data (threshold templates, their names, notification hold-down timers, and row-creation status) alongside monitoring/alarm data reflecting when interface utilization crosses defined limits. Its central use is performance and fault monitoring: it lets an operator detect when interface traffic exceeds set thresholds and triggers notification-hold-down-controlled alarms, a software-level traffic-health indicator rather than a physical hardware metric. The module explicitly notes it should be used instead of the EVENT-MIB when a threshold needs to apply to only one interface, indicating a direct relationship to the IETF EVENT-MIB as an alternative/overlapping mechanism. It is deployed on NMS Communications switches and routers in networks where administrators want a common set of interface traffic thresholds applied across many ports without configuring each individually. Engineers can download the NMS-IF-THRESHOLD-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NMS-IF-THRESHOLD-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
- nms Co., Ltd. switch/router (interface traffic threshold templates, vendor unidentified)
Monitoring Examples
An operator would create entries in nmsifthTemplateTable (indexed by nmsifthTemplateIndex, named via nmsifthTemplateName) defining a threshold template, then check nmsifthThresholdTable and nmsifthThresholdLastChange to see when a threshold breach last occurred on an assigned interface; a recent change timestamp combined with a notification would indicate a port has exceeded its configured utilization threshold. The nmsifthTemplateNotifyHoldDownTime object lets an admin confirm notification suppression windows are set correctly to avoid alarm flooding.
What Can Be Monitored
- interface utilization threshold breaches
- threshold template configuration
- notification hold-down timing
- last threshold change time

| nmsIfThresholdMIB | 1.3.6.1.4.1.11606.10.9.218 | This MIB module defines the managed objects that support monitoring of thresholds on interfaces. Configuration and monitoring of the thresholds is done through threshold templates that can be assigned to any subset of interfaces on the network element. More than one threshold template can be assigned to a given interface. This MIB module should be used when it is desired to apply a common set of thresholds to a subset of the available interfaces. If a threshold is to be applied to only one interface, then the EVENT-MIB or the RMON-MIB may be used as simpler alternatives. If a threshold is to be applied to all available interfaces, then the EVENT-MIB may be used as a simpler alternative. | ||

| nmsifthTemplateGroup | 1.3.6.1.4.1.11606.10.9.218.1.1 | |||
| NMS nmsifthTemplateIndexNext | 1.3.6.1.4.1.11606.10.9.218.1.1.1 | NMSifthTemplateIndexOrZero | read-only | This object contains an appropriate value to be used for nmsifthTemplateIndex when creating entries in the nmsifthTemplateTable. The distinguished value 0 indicates that no unassigned entries are available. To obtain a suggested nmsifthTemplateIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. The manager may ignore this object and use alternative mechanisms for choosing an unused value of nmsifthTemplateIndex for a new entry. The agent will modify the value to the next unassigned index, when a new entry is created in nmsifthTemplateTable with the current value of this object. After deletion of an entry in nmsifthTemplateTable the agent will determine through its local policy when its index value will be made available for reuse. |
| TIM nmsifthTemplateLastChange | 1.3.6.1.4.1.11606.10.9.218.1.1.2 | TimeStamp | read-only | This object specifies the value of sysUpTime at the last time there was either a change to any object in any entry in nmsifthTemplateTable, or an entry was created or destroyed in nmsifthTemplateTable. If no change to nmsifthTemplateTable has occurred since the last re-initialization of the local network management subsystem, then this object contains a zero value. |
| nmsifthTemplateTable | 1.3.6.1.4.1.11606.10.9.218.1.1.3 | not-accessible | This table is used to create threshold templates. Each template includes one or more thresholds (defined in the nmsifthThresholdTable), and can be assigned to multiple interfaces. An interface may be associated with more than one template. The assignment of templates to interfaces is done in the nmsifthTemplateIfAssignTable. | |
| nmsifthTemplateEntry | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1 | not-accessible | An entry describing the general properties of a threshold template. The template is created using the nmsifthTemplateRowStatus object. Prior to creating an entry in the table, the manager should obtain a unique value of nmsifthTemplateIndex by reading the nmsifthTemplateIndexNext object. The values of nmsifthTemplateName and nmsifthTemplateNotifyHoldDownType must be provided before activating the entry. After creating an entry, thresholds can be defined for the template by creating entries with the same value of nmsifthTemplateIndex in the nmsifthThresholdTable. The template can then be assigned to one or more interfaces using the nmsifthTemplateIfAssignTable. Once an entry has been activated, the value of nmsifthTemplateName cannot be modified. In order to use a new value of nmsifthTemplateName, a new template must be defined. The values of nmsifthTemplateNotifyHoldDownType and nmsifthTemplateNotifyHoldDownTime may be modified when the entry is active. See the description clause of nmsifthTemplateNotifyHoldDownType for further caveats on modification of that object. | |
| NMS nmsifthTemplateIndex | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1.1 | NMSifthTemplateIndex | not-accessible | An arbitrary integer that uniquely identifies a threshold template. The value for each threshold template must remain constant at least from one re-initialization of the agent's network management system to the next re-initialization. The value may change when the agent's network management system is rebooted or re-initialized. |
| STR nmsifthTemplateName | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1.2 | SnmpAdminString | read-create | This object specifies a unique name associated with the threshold template by the management client, and provides a non-volatile 'handle' for the template. The name must not include whitespace characters. After this value has been written to the startup configuration, the agent must retain the value until a management client deletes it. The level of retention must span reboots and re-initializations of the agent, including those that result in different assignments to the value of nmsifthTemplateIndex associated with this template. Once an entry has been activated, this value cannot be modified. In order to use a new value of nmsifthTemplateName, a new template must be defined. |
| INT nmsifthTemplateNotifyHoldDownType | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1.3 | INTEGER | read-create | This object specifies the method used to prevent an excess of notifications from being generated when operation fluctuates around a threshold level. The value 'holdDownTimer' indicates that notifications for a given threshold and interface are suppressed for a short amount of time after each notification. The time value is specified in nmsifthTemplateNotifyHoldDownTime, which is instantiated only when this object is set to 'holdDownTimer'. After a notification is received for a given threshold and interface, the next notification for that threshold and interface will be generated after at least nmsifthTemplateNotifyHoldDownTime amount of time has passed, only when the threshold is next fired or cleared. The value 'fireAndClearThresholds' indicates that hysteresis is used. The management client configures two values for each threshold: one for asserting that the threshold has been exceeded (see nmsifthThresholdFiredValue), and a second value for asserting that the threshold is no longer being exceeded (see nmsifthThresholdClearedValue, which is instantiated only when this object is set to 'fireAndClearThresholds'). When this entry in nmsifthTemplateTable is active, this object may only be modified if there are no active entries in nmsifthThresholdTable with the same value of nmsifthTemplateIndex. |
| U32 nmsifthTemplateNotifyHoldDownTime | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1.4 | Unsigned32 | read-create | The minimum amount of time between successive nmsifthIfThresholdFired or nmsifthIfThresholdCleared notifications for a given interface and template. This object is instantiated only when nmsifthTemplateNotifyHoldDownType is set to 'holdDownTimer'. |
| ROW nmsifthTemplateRowStatus | 1.3.6.1.4.1.11606.10.9.218.1.1.3.1.5 | RowStatus | read-create | This object is used to create and delete threshold templates. The values of nmsifthTemplateName and nmsifthTemplateNotifyHoldDownType must be provided before activating the entry. An entry can only be deleted when there are no active entries in the nmsifthTemplateIfAssignTable with the same value of nmsifthTemplateIndex. When an entry is deleted, all associated entries in the nmsifthThresholdTable are also deleted. After the entry has been activated, this object cannot be set to any value other than 'destroy'. The row status never changes to 'notInService' after reaching the value 'active'. |
| TIM nmsifthThresholdLastChange | 1.3.6.1.4.1.11606.10.9.218.1.1.4 | TimeStamp | read-only | This object specifies the value of sysUpTime at the last time there was either a change to any object in any entry in nmsifthThresholdTable, or an entry was created or destroyed in nmsifthThresholdTable. If no change to nmsifthThresholdTable has occurred since the last re-initialization of the local network management subsystem, then this object contains a zero value. |
| nmsifthThresholdTable | 1.3.6.1.4.1.11606.10.9.218.1.1.5 | not-accessible | This table specifies the interface thresholds used in each template. | |
| nmsifthThresholdEntry | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1 | not-accessible | An entry specifying an interface threshold used in a threshold template. The entry is created using the nmsifthThresholdRowStatus object. The values of nmsifthThresholdObject, nmsifthThresholdSeverity, nmsifthThresholdType, and nmsifthThresholdFiredValue must be provided before activating the entry. If the value of nmsifthTemplateNotifyHoldDownType in the nmsifthTemplateEntry with the same value of nmsifthTemplateIndex is 'fireAndClearThresholds', then the value of nmsifthThresholdClearedValue must also be provided before activating the entry. If the value of nmsifthThresholdType is other than 'rateOfIncreaseExponentXIfSpeed', then the value of nmsifthThresholdSampleInterval must also be provided before activating the entry. The agent should not allow creation of two entries in the table with the same values of nmsifthTemplateIndex, nmsifthThresholdObject, nmsifthThresholdSeverity, and nmsifthThresholdDirection. Once an entry has been activated, the values of nmsifthThresholdObject, nmsifthThresholdSeverity, nmsifthThresholdType, and nmsifthThresholdDirection cannot be modified. In order to use new values of these objects, a new threshold must be defined. The values of nmsifthThresholdDescr, nmsifthThresholdFiredValue, nmsifthThresholdClearedValue, nmsifthThresholdSampleInterval, and nmsifthThresholdApsSwitchover may be modified when the entry is active. | |
| NMS nmsifthThresholdIndex | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.1 | NMSifthThresholdIndex | not-accessible | An arbitrary integer that uniquely identifies a threshold in a threshold template. The value for each threshold must remain constant when the agent's network management system is rebooted or re-initialized. |
| STR nmsifthThresholdDescr | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.2 | SnmpAdminString | read-create | A description of the threshold's function and use. The description must not include carriage returns. |
| OID nmsifthThresholdObject | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.3 | OBJECT IDENTIFIER | read-create | The object to be compared against the threshold values. The object must be defined in a table indexed only by ifIndex. All of the instance portion of the object identifier is truncated, since the instance(s) to be compared against the threshold are identified using the nmsifthTemplateIfAssignTable. If the object has syntax 'Integer32', 'Unsigned32', or 'Gauge32', then nmsifthThresholdType should be set to 'absoluteValue'. If the object has syntax 'Counter32' or 'Counter64', then nmsifthThresholdType should be set to 'deltaValue' or 'rateOfIncreaseExponentXIfSpeed'. |
| NMS nmsifthThresholdSeverity | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.4 | NMSifthThresholdSeverity | read-create | This object specifies the severity associated with the condition when the threshold is exceeded. |
| INT nmsifthThresholdType | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.5 | INTEGER | read-create | The manner in which to compare nmsifthThresholdObject to nmsifthThresholdFiredValue and nmsifthThresholdClearedValue. The value 'absoluteValue' indicates that the value of nmsifthThresholdObject is to be compared directly to nmsifthThresholdFiredValue or nmsifthThresholdClearedValue. The value 'deltaValue' indicates that the difference between two successive samples of nmsifthThresholdObject is to be compared to nmsifthThresholdFiredValue or nmsifthThresholdClearedValue. The polling interval between successive samples is defined in nmsifthThresholdSampleInterval. The value 'rateOfIncreaseExponentXIfSpeed' indicates that the rate of increase of nmsifthThresholdObject is to be compared to the negated value of nmsifthThresholdFiredValue used as the exponent of 10, times the value of ifSpeed (if the value of ifSpeed is less than the maximum value) or ifHighSpeed (otherwise). For example, a value of nmsifthThresholdFiredValue of 5 on a gigabit ethernet interface indicates a threshold of 10^-5 times the interface speed, which is equal to 10,000 per second. When the value of this object is 'rateOfIncreaseExponentXIfSpeed', the polling interval between successive samples is determined automatically by the agent. When the object identified by nmsifthThresholdObject is a counter, a threshold type of 'deltaValue' or 'rateOfIncreaseExponentXIfSpeed' should be used. When the object identified by nmsifthThresholdObject is not a counter, a threshold type of 'absoluteValue' should be used. |
| INT nmsifthThresholdDirection | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.6 | INTEGER | read-create | This object indicates which direction of movement causes the threshold to fire. The value 'rising' indicates that the threshold is fired when the current sampled value is numerically greater than or equal to the value of nmsifthThresholdFiredValue, and the threshold was considered to be cleared at the last sampling interval. If the value of the corresponding nmsifthTemplateNotifyHoldDownType object is 'fireAndClearThresholds', the threshold is cleared when the current sampled value is less than the value of nmsifthThresholdClearedValue, and the threshold was considered to be fired at the last sampling interval. If the value of the corresponding nmsifthTemplateNotifyHoldDownType object is other than 'fireAndClearThresholds', the threshold is cleared when the current sampled value is less than the value of nmsifthThresholdFiredValue, and the threshold was considered to be fired at the last sampling interval. The value 'falling' indicates that the threshold is fired when the current sampled value is numerically less than or equal to the value of nmsifthThresholdFiredValue, and the threshold was considered to be cleared at the last sampling interval. If the value of the corresponding nmsifthTemplateNotifyHoldDownType object is 'fireAndClearThresholds', the threshold is cleared when the current sampled value is greater than the value of nmsifthThresholdClearedValue, and the threshold was considered to be fired at the last sampling interval. If the value of the corresponding nmsifthTemplateNotifyHoldDownType object is other than 'fireAndClearThresholds', the threshold is cleared when the current sampled value is greater than the value of nmsifthThresholdFiredValue, and the threshold was considered to be fired at the last sampling interval. |
| I32 nmsifthThresholdFiredValue | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.7 | Integer32 | read-create | A threshold value to check against the object identified in nmsifthThresholdObject. If the value of nmsifthThresholdDirection is 'rising', then the threshold is fired when the current sampled value (absolute, delta, or rate of increase, depending on the value of nmsifthThresholdType) of the object identified in nmsifthThresholdObject is greater than or equal to this value. If the value of nmsifthThresholdDirection is 'falling', then the threshold is fired when the current sampled value (absolute, delta, or rate of increase, depending on the value of nmsifthThresholdType) of the object identified in nmsifthThresholdObject is less than or equal to this value. |
| I32 nmsifthThresholdClearedValue | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.8 | Integer32 | read-create | A threshold value to check against the object identified in nmsifthThresholdObject. If the value of nmsifthThresholdDirection is 'rising', then the threshold is cleared when the current sampled value (absolute, delta, or rate of increase, depending on the value of nmsifthThresholdType) of the object identified in nmsifthThresholdObject is less than this value. If the value of nmsifthThresholdDirection is 'falling', then the threshold is cleared when the current sampled value (absolute, delta, or rate of increase, depending on the value of nmsifthThresholdType) of the object identified in nmsifthThresholdObject is greater than this value. This object is instantiated only when the value of nmsifthTemplateNotifyHoldDownType in the nmsifthTemplateEntry with the same value of nmsifthTemplateIndex is 'fireAndClearThresholds'. |
| U32 nmsifthThresholdSampleInterval | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.9 | Unsigned32 | read-create | The number of milliseconds to wait between samples of the object identified in nmsifthThresholdObject. To encourage consistency in sampling, the interval is measured from the beginning of one check to the beginning of the next and the timer is restarted immediately when it expires, not when the check completes. This object is not instantiated when the value of nmsifthThresholdType is 'rateOfIncreaseExponentXIfSpeed'. |
| T/F nmsifthThresholdApsSwitchover | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.10 | TruthValue | read-create | This object indicates whether automatic protection switching (APS) switchover should be triggered, if applicable, when the threshold is fired. The value of this object takes effect when the template identified by nmsifthTemplateIndex is assigned to an interface that is part of an APS group. One way to configure an interface in an APS group is using the cApsChanConfigTable in the NMS-APS-MIB. |
| ROW nmsifthThresholdRowStatus | 1.3.6.1.4.1.11606.10.9.218.1.1.5.1.11 | RowStatus | read-create | This object is used to create and delete thresholds in templates. A new entry can only be created when there is an active entry in the nmsifthTemplateTable with the same value of nmsifthTemplateIndex. The values of nmsifthThresholdObject, nmsifthThresholdSeverity, nmsifthThresholdType, and nmsifthThresholdFiredValue must be provided before activating the entry. If the value of nmsifthTemplateNotifyHoldDownType in the nmsifthTemplateEntry with the same value of nmsifthTemplateIndex is 'fireAndClearThresholds', then the value of nmsifthThresholdClearedValue must also be provided before activating the entry. If the value of nmsifthThresholdType is other than 'rateOfIncreaseExponentXIfSpeed', then the value of nmsifthThresholdSampleInterval must also be provided before activating the entry. When an entry is activated, if there are any entries in nmsifthTemplateIfAssignTable with the same value of nmsifthTemplateIndex, then the threshold is activated on all interfaces identified in those entries that have instances of the object identified by nmsifthThresholdObject. When an entry is destroyed, if there are any entries in nmsifthTemplateIfAssignTable with the same value of nmsifthTemplateIndex, then the threshold is de-activated on the interfaces identified in those entries. If there are any entries in nmsifthIfThresholdFiredTable with nmsifthIfThresholdFiredTemplate value equal to this value of nmsifthTemplateIndex, then the bit in nmsifthIfThresholdsFired corresponding to this threshold is cleared in all such entries. After the entry has been activated, this object cannot be set to any value other than 'destroy'. The row status never changes to 'notInService' after reaching the value 'active'. |
| nmsifthTemplateIfAssignGroup | 1.3.6.1.4.1.11606.10.9.218.1.2 | |||
| TIM nmsifthTemplateIfLastChange | 1.3.6.1.4.1.11606.10.9.218.1.2.1 | TimeStamp | read-only | This object specifies the value of sysUpTime at the last time there was either a change to any object in any entry in nmsifthTemplateIfAssignTable, or an entry was created or destroyed in nmsifthTemplateIfAssignTable. If no change to nmsifthTemplateIfAssignTable has occurred since the last re-initialization of the local network management subsystem, then this object contains a zero value. |
| nmsifthTemplateIfAssignTable | 1.3.6.1.4.1.11606.10.9.218.1.2.2 | not-accessible | This table specifies the assignment of threshold templates to specific interfaces. Each threshold template may be assigned to multiple interfaces. Each interface may have multiple threshold templates assigned to it. | |
| nmsifthTemplateIfAssignEntry | 1.3.6.1.4.1.11606.10.9.218.1.2.2.1 | not-accessible | An entry describing the assignment of a particular threshold template to a particular interface. The entry is created using the nmsifthTemplateIfAssignRowStatus object. | |
| NUM nmsifthTemplateIfAssignInterface | 1.3.6.1.4.1.11606.10.9.218.1.2.2.1.1 | InterfaceIndex | not-accessible | This object identifies an interface to which the template is assigned. |
| INT nmsifthTemplateIfAssignOperStatus | 1.3.6.1.4.1.11606.10.9.218.1.2.2.1.2 | INTEGER | read-only | This object indicates whether the threshold template identified by nmsifthTemplateIndex is operational on the interface identified by nmsifthTemplateIfAssignInterface. When the value of this object is 'up', this indicates that the thresholds in this template (identified by nmsifthTemplateIndex) are activated on this interface, with the following exception: If a threshold is defined on an object that does not have an instance for this interface, then the threshold is not activated on this interface. If any of the thresholds are being exceeded, then a corresponding entry exists in the nmsifthIfThresholdFiredTable. When the value of this object is 'down', this indicates that all thresholds in the template are de-activated on this interface and there is no corresponding entry in the nmsifthIfThresholdFiredTable, regardless of whether any of the thresholds in the template are being exceeded on this interface. One reason for a template not to be operational on an interface to which it is assigned is when the interface has two (or more) templates assigned to it that contain thresholds on the same object with the same severity and direction, i.e., thresholds with the same values of nmsifthThresholdObject, nmsifthThresholdSeverity, and nmsifthThresholdDirection. This may occur when a template is assigned to the interface, or when a threshold is added to a template that is already active on the interface. When this occurs, the implementation may operate on both (or all) threshold values, or it may take down one (or more) of the templates on this interface, which is indicated by changing the value of this object from 'up' to 'down'. |
| ROW nmsifthTemplateIfAssignRowStatus | 1.3.6.1.4.1.11606.10.9.218.1.2.2.1.3 | RowStatus | read-create | This object is used to create and delete entries in the table, assigning templates to interfaces and removing templates from interfaces, respectively. A new entry can only be created when there is an active entry in the nmsifthTemplateTable with the same value of nmsifthTemplateIndex. When an entry is activated, the thresholds in this template (identified by nmsifthTemplateIndex) are activated on this interface, with the following exception: If a threshold is defined on an object that does not have an instance for this interface, then the threshold is not activated on this interface. When an entry is destroyed, all thresholds in the template are de-activated on this interface and the corresponding entry in the nmsifthIfThresholdFiredTable is deleted, if it exists. After the entry has been activated, this object cannot be set to any value other than 'destroy'. The row status never changes to 'notInService' after reaching the value 'active'. |
| nmsifthIfThresholdFiredGroup | 1.3.6.1.4.1.11606.10.9.218.1.3 | |||
| NMS nmsifthThresholdFiredNotifyEnable | 1.3.6.1.4.1.11606.10.9.218.1.3.1 | NMSifthThresholdSeverityOrZero | read-write | This object specifies the minimum severity threshold governing the generation of nmsifthIfThresholdFired and nmsifthIfThresholdCleared notifications. For example, if the value of this object is set to 'degrade', then the agent generates these notifications if and only if the severity of the threshold being exceeded is 'degrade' or 'fail'. When the value is other than '0', the generation of nmsifthTemplateIfStatusChange notifications is also enabled. The value of '0' disables the generation of all notifications. By default, the value of this object is set to '0'. |
| TIM nmsifthThresholdFiredLastChange | 1.3.6.1.4.1.11606.10.9.218.1.3.2 | TimeStamp | read-only | This object specifies the value of sysUpTime at the last time there was either a change to any object in any entry in nmsifthIfThresholdFiredTable, or an entry was added or deleted in nmsifthIfThresholdFiredTable. If no change to nmsifthIfThresholdFiredTable has occurred since the last re-initialization of the local network management subsystem, then this object contains a zero value. |
| nmsifthIfThresholdFiredTable | 1.3.6.1.4.1.11606.10.9.218.1.3.3 | not-accessible | This table indicates the interfaces that currently have threshold fired conditions. | |
| nmsifthIfThresholdFiredEntry | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1 | not-accessible | An entry indicating an interface that currently has one or more threshold fired conditions based on one template. | |
| NMS nmsifthIfThresholdFiredTemplate | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.1 | NMSifthTemplateIndex | not-accessible | This object specifies a template for which one or more of the thresholds are fired on this interface. |
| NMS nmsifthIfThresholdsFired | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.2 | NMSifthThresholdList | read-only | This object specifies those thresholds that are currently being exceeded on this interface. If a threshold is currently being exceeded (i.e., the threshold is fired) on the interface, then the corresponding bit in the threshold list is set to one. Otherwise, the bit will be set to zero, or the bit will not be present. Only the first N octets are present in the threshold list, such that the highest octet present has at least one bit set to '1'. All higher octets with value '0' are truncated. |
| NMS nmsifthIfLastThresholdFired | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.3 | NMSifthThresholdIndex | read-only | This object specifies the last threshold fired or cleared on the interface. |
| TIM nmsifthIfThresholdFiredLstChange | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.4 | TimeStamp | read-only | This object specifies the value of sysUpTime at the last time a threshold was fired or cleared on the interface. |
| NMS nmsifthIfThresholdFiredLstSeverity | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.5 | NMSifthThresholdSeverity | read-only | This object specifies the severity of the threshold that was last fired or cleared on the interface. |
| NMS nmsifthIfThresholdFiredMaxSeverity | 1.3.6.1.4.1.11606.10.9.218.1.3.3.1.6 | NMSifthThresholdSeverity | read-only | This object specifies the highest severity among the thresholds that are currently being exceeded on this interface. |

| NTF nmsifthIfThresholdFired | 1.3.6.1.4.1.11606.10.9.218.2.0.1 | The agent generates this notification when a threshold defined in a template is asserted on an interface. If a threshold is asserted for a given interface and template, nmsifthTemplateNotifyHoldDownTime is set to 'holdDownTimer' for that template, and this notification has recently been sent for the same threshold on the same interface, then this notification may be suppressed. | ||
| NTF nmsifthIfThresholdCleared | 1.3.6.1.4.1.11606.10.9.218.2.0.2 | The agent generates this notification when a threshold, that has previously fired, is cleared on an interface. If a threshold is cleared for a given interface and template, nmsifthTemplateNotifyHoldDownTime is set to 'holdDownTimer' for that template, and this notification has recently been sent for the same threshold on the same interface, then this notification may be suppressed. | ||
| NTF nmsifthTemplateIfStatusChange | 1.3.6.1.4.1.11606.10.9.218.2.0.3 | The agent generates this notification when a template comes up or goes down on an interface to which it is assigned, i.e., when the value of nmsifthTemplateIfAssignOperStatus changes. If a template becomes operationally down on an interface upon activation of a new entry in the nmsifthTemplateIfAssignTable, the agent generates this notification. The agent need not generate this notification when a new entry in the nmsifthTemplateIfAssignTable is activated, if the template becomes operational on the interface. The agent need not generate this notification when an entry in the nmsifthTemplateIfAssignTable is destroyed. | ||
