SCTE-HMS-HE-COMMON-MIB: View SNMP OID List / Download MIB

The SNMP trap that is generated when an alarm event is found. At the option of the unit, the heCommonLogText variable may be reported as a fifth varbind, for those instances where an additional text field is supported.

The MIB module is for representing general information about optical equipment present in the headend (or indoor) and is supported by an SNMP agent.

A table containing information about headend (or indoor) equipment.

Information about particular headend equipment.

Real time clock.

Temperature measured inside the headend equipment. This object must provide for the alarm management capabilities with a corresponding entry in the propertyTable of SCTE-HMS-PROPERTY-MIB (HMS026). An alarm shall be recorded as an entry in the currentAlarmTable of SCTE-HMS-PROPERTY-MIB (HMS026). A log record shall be added as an entry in the heCommonLogTable. An heCommonAlarmEvent notification shall be sent.

This object is used to reset software of the headend physical entity. A SET request with the value reset(1) only shall reset the software application. The reset implementation is vendor specific. A GET request shall always return the value reset(1) and shall have no effect on the entity. Enumeration: 'reset': 1.

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. Enumeration: 'detectionDisabled': 1, 'detectionEnabled': 2, 'detectionEnabledAndRegenerate': 3.

The current number of entries in the heCommonLogTable. Before the very first wrap-around condition occurs for heCommonLogIndex, heCommonLogNumberOfEntries will return the total number of entries logged in heCommonLogTable, since the unit was powered up. After the first wrap-around condition has occured for for the value of the MIB variable heCommonLogIndex, heCommonLogNumberOfEntries will return the maximum number of rows the heCommonLogTable can hold.

Index of the most recent alarm entry logged in the heCommonLogTable. The value of this variable can be used as the value of heCommonLogIndex to retrieve the most recent logged entry.

A list of alarms that have been logged. Agent should generate the SNMP HMS notification every time a new alarm entry is logged. This table should support a minimum of 16 entries.

A set of data describing an alarm event that has been logged.

An index that uniquely identifies an entry in the log table. Indexes are assigned beginning with 1 and increased by one with each new log entry up to 65535. The next entry after 65535 is one. The agent may choose to delete the oldest instances of heCommonLogEntry as required because of lack of memory. It is an implementation-specific matter as to when this deletion may occur. Note - The wrap-around for the heCommonLogIndex variable MUST occur after 65535 regardless of the implementation specific size of the hlCommonLogTable.

This is the OID of the object that has changed alarm state.

This is the value of the object at the time it changed alarm state.

The new alarm state of the object which caused the event to be recorded into the log. Enumeration: 'heCommonLO': 4, 'heCommonLOLO': 5, 'heCommonHIHI': 2, 'heCommonHI': 3, 'heCommonDiscreteMajor': 6, 'heCommonNominal': 1, 'heCommonDiscreteMinor': 7.

This is the time when the alarm change for the object occured.

This is a text field describing the alarm. This field could be a zero length string in certain agent implementations.

The compliance statement for SNMP entities which implement this MIB.

The collection of objects which are used to represent the common parameters of the headend managed entities.

The collection of objects which are used to record an alarm event into the headend agent log.

The collection of notifications used by the headend agent to report the exceptional conditions to the management application.
