7.5.1
PET is the ASF transmit protocol used to provide common fields for trap regardless of trap source.
The variable bindings fields in a PET frame contain the system and sensor information for an event,
such as event sensor type, event type, event offset, event source type, sensor device, sensor number,
entity ID, entity instance, event status index, event status, and event severity. Each field has its
definition and is described in the following table.
Event Sensor Type
Event Type
Event Offset
Event source Type
Sensor Device
Sensor Number
Entity ID
Entity Instance
Event Status Index
Event Status
Event Severity

FIELD
The Event Sensor Type field indicates what types of events the
The Entity Instance indicates which instance of the Entity the event is
sensor is monitoring. E.g. temperature, voltage, fan, etc.
The Event Type indicates what type of transition/state change
triggered the trap.
The Event Offset indicates which particular event occurred for a given
Even Type.
The Event Source Type describes the originator of the event. It is
ASF2.0(68h) for all PET frames defined by this specification.
The Sensor Device is the SMBus address of the sensor that caused
the event for the PET frame.
The Sensor Number is used to identify a given instance of a sensor
relative to the Sensor Device.
The Entity ID indicates the platform entity the event is associated with.
E.g. processor, system board, etc.
for. E.g. processor 1 or processor 2.
The Event Status Index identifies a unique event monitored by the
ASF-sensor. It is zero-based, sequential, continuous, and ranging
form 0-37h.
The Event Status indicates the event state of the ASF-sensor device
associated with the message’s Event Status Index.
The Event Severity gives the management station an indication of the
severity of the event in the PET frame. Typical values are Monitor
(0x01), Non Critical (0x08), or Critical Condition (0x10).
