How can i write to qsfp+ eeprom

I want to write to eeprom qsfp+ via ConnectX-5 EN dual port. I used to read eeprom util “mlxcables”, so according to mft 4.12 this utility can read/write. But help does not show option write, and when i try to use it, it prints me, that i have to give it some param, i think it addres or may be page, offset and data. Can you give some explain? Or may be I can do it other way?

P.S. Mellanox qsfp+ active fiber cable

Hi Ivan,

Writing into QSFP is not possible.

This is an internal option of the mlxcables tool and can be done only by Mellanox engineers.

Best Regards,
