cmEthernetNetPortStatsTemp
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmEthernetNetPortStatsTemp
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.5.1.40
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The temperature of the physical layer when media type is fiber.
What is cmEthernetNetPortStatsTemp?
This Integer32 value is the temperature of the physical layer, applicable only when the port media is fiber. An admin watches it because rising optical-module temperature, independent of ambient conditions, often precedes a hard optical failure. If cmEthernetNetPortStatsTemp on network (uplink) port 8 reads 52 C at the current interval while nearby ports of the same type run noticeably cooler, an operator would flag that specific module for airflow or replacement checks.
