Type: INTEGER
Access: read-write
Description: This object is used to control the detection of alarms in this headend entity.
Each headend entity may provide for the alarm management capabilities. The provisions shall be done by means of the propertyTable and/or the discretePropertyTable of SCTE-HMS-PROPERTY-MIB (HMS026).
When a threshold from either the propertyTable or the discretePropertyTable is crossed in a manner described by SCTE-HMS-PROPERTY-MIB (HMS026), then an alarm is said to have occurred. When the alarm is detected, then
(1) an entry is placed in the heCommonLogTable, which serves as a log of the most recent alarm events;
(2) an heCommonAlarmEvent trap is generated;
(3) a property which is not in the nominal state will have an entry in the currentAlarmTable of SCTE-HMS-PROPERTY-MIB.
The detectionDisabled(1) value prevents the threshold detection process associated with the property table and discrete property table from running. The headend entity shall not generate alarms. The contents of the heCommonLogTable, currentAlarmTable, each instance of discreteAlarmState, and each instance of currentAlarmState shall remain in the state prior to detectionDisabled(1) being applied.
The detectionEnabled(2) value permits alarm detection to run. The detection process continues from the state the headend entity was in prior to detectionEnabled(2) being set.
The detectionEnabledAndRegenerate(3) value clears all alarm information and permits alarm detection to run. All alarm properties, both discrete and analog, are restored to the nominal value before alarm detection runs. Any properties that are in an alarm state SHALL NOT produce a 'return to normal' alarm as part of the process. Setting this value clears the heCommonLogTable and the currentAlarmTable.
The detectionEnabledAndRegenerate(3) value is transient, that is a SET request with a value detectionEnabledAndRegnerate(3) shall return the same value detectionEnabledAndRegnerate(3). Subsequent GET requests shall return a value detectionEnabled(2).
The detectionDisabled(1) value shall affect the generation of heCommonAlarmEvent trap only. Traps added in the future are assumed to be unaffected by this object, unless stated in the description of that trap.
This object has a default value of detectionEnabled(2).
The value shall be maintained in non-volatile memory.
What is heCommonAlarmDetectionControl?
This read-write value controls whether the headend entity's threshold-based alarm detection runs at all, with detectionDisabled(1) halting new alarm generation while preserving existing alarm state, detectionEnabled(2) resuming detection from its prior state, and detectionEnabledAndRegenerate(3) clearing all alarm history and restarting detection fresh, defaulting to detectionEnabled(2). An admin uses detectionDisabled to quiet alarm generation during planned maintenance without losing historical alarm records, and detectionEnabledAndRegenerate to wipe stale alarm state and start clean, noting that a SET to detectionEnabledAndRegenerate(3) is transient and subsequent reads return detectionEnabled(2). For example, an admin performing scheduled maintenance that would otherwise trigger nuisance alarms would set this to detectionDisabled(1) beforehand, then back to detectionEnabled(2) once work is complete.
