hmSfpTemperature
Module: HMPRIV-MGMT-SNMP-MIB
OID (symbolic): HMPRIV-MGMT-SNMP-MIB::hmSfpTemperature
OID (numeric): 1.3.6.1.4.1.248.14.1.1.13.1.12
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This signed integer is used to identify the temperature within the SFP in units of centigrade (celsius). Contains -1000 in case of a device read error.
What is hmSfpTemperature?
This object reports the current temperature inside a Small Form Factor Pluggable (SFP) optical transceiver in degrees Celsius. The value -1000 indicates a read error or sensor failure. Network operators monitor this to track SFP thermal conditions, prevent overheating damage to optics, and predict component failures.
Examples
