Is there a way to read the SFP SEEPROM data on all Ethernet adapters? ethtool does not work, see below using a X710 10GigE adapter with f/w 7.00, i40 driver 2.3.6, ethtool 5.

Hello Yusuf,

We apologize for the delay on this matter.

Kindly provide the markings of the X710 adapter. This would also help us in further checking your query.

You may refer to this link on where to find the PBA and serial number of the adapter.

Hi Crisselle!

We actually managed to find a solution to the issue. For future reference:

When working on SLES 11 SP3, with ethtool v4.5 and i40e v2.4.10, trying ethtool -m to read the EEPROM data failed, and said the module does not support the operation.

We switched to SLES 12 SP3, with the same version of ethtool and i40e, and then ethtool -m worked fine. We're not sure what caused the change or if there was a kernel dependency, but the OS update fixed the issue.
