ERROR : MT26448 ethtool - m > Cannot get module EEPROM information:Input/output error

Hello Marcelo,

Many thanks for posting your question on the Mellanox Community.

Based on the information provided, you are using a ConnectX adapter. This adapter is EOL and EOS for a while now.

Unfortunately the ethtool option ‘-m’ is not supported by this adapter.

Many thanks,

Thank you very much for responding.

Since you cannot use the ethtool-m command as an optical diagnostic support Tx power levels (Laser output power) and Rx power (Receiver signal average optical power), temperature, voltage and alarm threshold settings.

What tool should I use to see those parameters on MT26448?

We use Debian 8.11

Linux 3.16.0-4-amd64 # 1 SMP Debian 3.16.43-2 + deb8u3 (2017-08-15) x86_64 GNU / Linux

Without further ado, my best regards
