Environment Monitor MIB (ap-env-monitor.mib)

The following table describes the SNMP GET query names for the Environment Monitor MIB (ap-env-monitor.mib).

To form the OID for an object, append the value in the OID column to 1.3.6.1.4.1.9148.3.3.1. For example, the OID for apEnvMonI2CState is 1.3.6.1.4.1.9148.3.3.1.1.

SNMP GET Query Name OID Description
apEnvMonI2CState 1 State of the environmental monitor located in the chassis. Values are:
  • initial (1): environment is at the initial state
  • normal (2): environment is good; for example at low temperature
  • minor (3): environment is not good; for example fans speed is more than minor alarm threshold but less than major alarm threshold
  • major (4): environment is bad; for example an speed is more than major alarm threshold, but less than critical alarm threshold
  • critical (5): environment is very bad; for example fan speed is more than critical alarm threshold
  • shutdown (6): environment is at its worst, the system should be shutdown immediately
  • notPresent (7): environmental monitor is not present
  • notFunctioning (8): environmental monitor does not function properly; for example, IC2 failure or temperature sensor generates abnormal data
  • unknown (9): no information available because of internal error

The apEnvMonVoltageStatusEntry object has the OID 1.3.6.1.4.1.9148.3.3.1.2.1.1. This object is deprecated.

The apEnvMonTemperatureStatusEntry object has the OID 1.3.6.1.4.1.9148.3.3.1.3.1.1.

To form the OID for an object, append the value in the OID column to 1.3.6.1.4.1.9148.3.3.1.3.1.1. For example, the OID for apEnvMonTemperatureStatusType is 1.3.6.1.4.1.9148.3.3.1.3.1.1.2.

SNMP GET Query Name OID Description
apEnvMonTemperatureStatusType 2 Indicates the entity being monitored for temperature. Values are:
  • ds1624sMain (1)
  • ds1624sCPU (2)
  • lm84 (3)
  • lm75 (4)
  • lm75Main (5)
  • lm75Cpu (6)
  • lm75Phy (7)
apEnvMonTemperatureStatusDescr 3 Description of the temperature being monitored. It has the value of the Main Board PROM Temperature (in Celsius).
apEnvMonTemperatureStatusValue 4 The current temperature of the main board PROM in Celsius.
apEnvMonTemperatureState 5 Current state of the temperature which can have one of the following values:
  • 1: initial: Temperature is at its initial state.
  • 2: normal: The temperature is normal.
  • 6: shutdown: The system should be shutdown immediately
  • 7: not present: The temperature sensor does not exist
  • 8: not functioning: The temperature sensor is not functioning properly.
  • 9: unknown. Cannot obtain information due to an internal error.

Values specific to 3900/3950/4900:

  • 3: minor alarm - the temperature is greater than or equal to 69.7 degrees Celsius and less than 73.8 degrees Celsius.
  • 4: major alarm. The temperature is greater than or equal to 73.8 degrees Celsius and less than 77.9 degrees Celsius.
  • 5: critical alarm. The temperature is greater than or equal to 77.9 degrees Celsius.

In general, the critical alarm is sent at 95% of the maximum allowed temperature, the major alarm at 90%, and the minor alarm at 85%.
apEnvMonTemperatureSlotID 6 Slot for which this temperature is found.
apEnvMonTemperatureSlotType 7 Type of module found in this slot.
