NIC temp

moosport

Anyone able to get temp reading using

ifconfig -vvvm ix0

Not from the NIC itself. If it's an SFP NIC it can report the module temperature.

@stephenw10 its AOC-STG-I2S.
This is the output returned. I have seen screenshots of temp reported after the "vendor" line

@moosport said in NIC temp:

SFP-H10GB-CU1M

That looks like a DAC cable which often does not support that. Fibre SFP modules usually do though:

@stephenw10 yes, it is using DAC cable. For a brief moment I did consider if DAC was the reason. But it should be reporting the temp of the chip onboard. So why does the cable matter?

stephenw10

AFAIK there's no way of reading the actual NIC chip temperature there. If the module reports a value that's the only thing you can check.
