How do I change the MAC address for a MCX4131A-GCAT?

How do I change the MAC address for a

MCX4131A-GCAT? Trying to change it using FLINT results in a cryptic error. Using Ubuntu 20.04 with the newest MFT software installed.

The reason I need to change the MAC address is that somehow it became corrupted and it now shows as 0000001234.

Any help with this would be appreciated.

Hi Charles,

Please follow the below guide and let me know if it helps.



Thank you so much for your response. I’m sure I would have eventually stumbled upon the correct documents, but you link makes my job so much easier.

the command listed on the page you send me results in the following error:

For Example:

#flint -d /dev/mst/mt4117_pciconf0 -ocr hw set Flash0.WriteProtected=disabled

-W- Firmware flash cache access is enabled. Running in this mode may cause the firmware to hang.

-E- Command “Hw” requires at most 1 arguments, but 2 arguments were given

Any ideas what I’m doing wrong? Keep in mind I followed the example in the link you provided exactly.
