sheEthernetPortSfpTemperature
Module: SHE-ETHERNET-MIB
OID (symbolic): SHE-ETHERNET-MIB::sheEthernetPortSfpTemperature
OID (numeric): 1.3.6.1.4.1.231.7.1.2.2.1.5.1.1.1.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Internally measured transceiver temperature. Represented as a 16 bit signed twos complement value in increments of 1/256 degrees Celsius, yielding a total range of -128C to +128C. Temperature accuracy is vendor specific but must be better than 3 degrees Celsius over specified operating temperature and voltage.The temperature in degrees Celsius is given by the signed twos complement value with LSB equal to 1/256 C.
Coding examples: DECIMAL HIGH BYTE LOW BYTE +127.996 7F FF +1.000 01 00 +0.004 00 01 -0.004 FF FF -1.000 FF 00 -127.996 80 01 -128.000 80 00
Only valid if sheEthernetPortSfpDiagnosticValid entry is true.
What is sheEthernetPortSfpTemperature?
This read-only INTEGER (-32767 to 32767, in units of 1/256 degree Celsius per SFF-8472 table 3.17) reports the SFP transceiver's internally measured temperature as a signed twos-complement value, valid only when sheEthernetPortSfpDiagnosticValid is true. An admin monitors this to catch an overheating optical transceiver before it causes link errors or fails outright. A raw value corresponding to well above the module's rated operating temperature would tell an admin that SFP needs better cooling or replacement.
