Extreme System Sensor Notification MIB Objects

Table 1. Extreme System Sensor Notification MIB Objects
Trap name and OID Varbinds Description
extremeTempSensorStatusChange
1.3.6.1.4.1.1916.1.60.0.1
extremeTempSensorTransitionEvent
extremeTempSensorAggrStatus

This notification is generated whenever the status of any temperature sensor changes state between normal, alarm, and critical.

MIB object name and OID Access Description
extremeTempSensorAggrStatus
1.3.6.1.4.1.1916.60.1.1
Accessible for Notify

The aggregate status of the various temperature sensors. Each sensor state is encoded within this value and occupies four (4) bits. The most significant nibble in the first byte encodes the state of the sensor with index 1 and the least significant nibble, the sensor with index 2. In the second byte, the most significant nibble encodes the state of the sensor with index 3 and the least significant nibble, the sensor with index 4.

If there are odd number of sensors, the last nibble will always be zero (0x0000).

The nibbles are set as follows:

  • 0x0000 - for normal state
  • 0x0001 - for alarm state
  • 0x0010 - for critical state
extremeTempSensorTransitionEvent
1.3.6.1.4.1.1916.60.1.3
Accessible for Notify

This MIB identifies the actual temperature sensor state transition that triggers the generation of the extremeTempSensorStatusChange notification.

The values for each state change are:

  • 1 - Normal to Alarm
  • 2 - Alarm to Critical
  • 3 - Normal to Critical
  • 4 - Critical to Alarm
  • 5 - Alarm to Normal
  • 6 - Critical to Normal
