tmnxDDMTemperature
Module: TIMETRA-PORT-MIB
OID (symbolic): TIMETRA-PORT-MIB::tmnxDDMTemperature
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.2.4.31.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description:
The value of tmnxDDMTemperature indicates the current temperature of the SFF in 1/256th degrees Celsius.
If the SFF is externally calibrated, the objects tmnxDDMExtCalTemperatureSlope and tmnxDDMExtCalTemperatureOffset affect the temperature calculation.
The formula for translating between the value of tmnxDDMTemperature and degrees Celsius is: Internally Calibrated only: tmnxDDMTemperature / 256 Externally Calibrated: (tmnxDDMTemperature * (tmnxDDMExtCalTemperatureSlope / 256) + tmnxDDMExtCalTemperatureOffset) / 256
For example (internally calibrated SFP): The SNMP value 5734 is 22.4 degrees Celsius.
What is tmnxDDMTemperature?
This object reports the current temperature of a Small Form Factor (SFF) transceiver module measured in 1/256th degree Celsius units, allowing fine-grained thermal monitoring. Many transceivers include internal calibration or external calibration data to convert the raw value to actual degrees Celsius. A network operator would monitor this to detect overheating transceivers, plan cooling improvements, or predict component failures.
