Cause

information  returned by Oids from the Device  

Resolution

  1.  Perform an SNMPwalk to the target device. See Verify device data for NPM and SAM using SNMPwalk.
  2. Search the SNMP walk for the OID 1.3.6.1.4.1.9.9.13.1.5.1.3.
    Example: OID=.1.3.6.1.4.1.9.9.13.1.5.1.3.1058, Type=Integer, Value=6
  3. Compare the value given to the following key values:
    1. normal(1): the environment is good, such as low temperature.
    2. warning(2): the environment is bad, such as temperature above normal operation range but not too high.
    3. critical(3): the environment is very bad, such as temperature much higher than the normal operating limit.
    4. shutdown(4): the environment is the worst, the system should be shut down immediately. 
    5. notPresent(5): the environmental monitor is not present, such as temperature sensors do not exist.
    6. notFunctioning(6): the environmental monitor does not function properly, such as a temperature sensor generates abnormal data like 1000 C.
  4. If we are displaying the proper state then the you will need to work with the device manufacturer as it maybe an IOS issue, SNMP Issue, or frozen status.
