How To Change The SmartServer IoT MAC Address Back To Factory Default (KB1439)

    You may need to change a SmartServer IoT MAC address back to factory settings (label on the bottom). 

    The SmartServer MAC address will get changed If you restore a previously backed up image from a different SmartServer.  A clone doesn't change the MAC address on the new SmartServer


    These instructions require you to re-image the SmartServer as part of the process. In most cases, this means you need to have local access to the SmartServer so you can plug in an USB flash drive.  

     

    Instructions (read all before running):

    1. From a console, change the MAC ID back to the MAC ID on the label.  It is important that you do not reboot or power cycle after setting the MAC IDs.


    Format:

    sudo fw_setenv ethaddr <MAC Address 1>
    sudo fw_setenv eth1addr <MAC Address 2>


    Example:

    sudo fw_setenv ethaddr 00:d0:71:0a:e4:d4
    sudo fw_setenv eth1addr 00:d0:71:0a:e4:d5

    2. Now re-image to a release to make these take effect.  (It is important that you do not reboot or power cycle between steps 1 and 2)

    3. You are now back to where you started.  So, now you can do a clone which will preserve your MAC IDs (rather than a restore which wipes them out).
