    82574 Gbe MAC Programming

    john@vision4ce Community Member

      Hello,

       

      I am currently designing a new board which could include a number of 82574 Gbe controllers. This would be the first time I have implemented Gbe controllers on board (as opposed to hosting mPCIe cards which already have 82574 Gbe controllers onboard).

       

      One of my concerns is the allocation and assignment of MAC addresses for the controllers.

      - Does this have to be done by pre-programming NVM before assembling the circuit card, or can it be done by writing to NVM when the board is assembled?

      - Is the only way of obtaining MAC addresses to go through the IEEE Registration Authority?

       

      Thanks for your help.

       

      Regards, John
