<p class="MsoNormal">This one has bugged me for a while.<br>
<br>
I understand that the numbering of network interfaces can change when adding a network card. What I can't figure out is why it's inconsistent. I have two identical servers, same mobo, same NICs in slot 1, same firmware, etc. I add a NIC in slot 2 on both severs
and reboot. Why does one show the new NIC as eth0 and the other shows the new NIC as eth1?<br clear="all">
