<ethernet_settings>
<ethernet>
    <ethernet_interface>Management</ethernet_interface>
    <media>autoselect</media>
    <media_opt></media_opt>
    <macaddr>00:c0:9f:3a:ec:1e</macaddr>
</ethernet>
<ethernet>
    <ethernet_interface>Data 2</ethernet_interface>
    <media>autoselect</media>
    <media_opt></media_opt>
    <macaddr>00:0e:0c:33:32:8a</macaddr>
</ethernet>
<ethernet>
    <ethernet_interface>Data 1</ethernet_interface>
    <media>autoselect</media>
    <media_opt></media_opt>
    <macaddr>00:c0:9f:3a:ec:1f</macaddr>
