heCommonAlarmDetectionControl OBJECT-TYPE
SYNTAX INTEGER {detectionDisabled(1), detectionEnabled(2), detectionEnabledAndRegenerate(3)}
MAX-ACCESS read-write
STATUS current
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."
