18.11.6 Alarm RMON Group
The Alarm group consists of the alarmTable, which periodically compares sampled values with
configured thresholds and raises an event if a threshold is crossed. This group requires the
implementation of the event group, which follows this section.
18.11.6.1 Alarm Table
The NMS uses the alarmTable to determine and provision network performance alarmable thresholds.
18.11.6.2 Row Creation in alarmTable
To create a row in the alarmTable, the SetRequest PDU must be able to create the row in one single-set
operation. All OIDs in the SetRequest PDU should be type OID.0 type for entry creation. The table has
a maximum number of 256 rows.
To create a SetRequest PDU for the alarmTable, the following values are required:

and returns an error code.
