Configuring eth0 and eth1 on PowerEdge 2900 assigns both to same adapter

  • 772

I have the following in my /etc/network/interfaces file

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address xxx.xxx.xxx.xxx
netmask xxx.xxx.xxx.xxx
gateway xxx.xxx.xxx.xxx

auto eth1
iface eth1 inet static
address xxx.xxx.xxx.xxx
netmask xxx.xxx.xxx.xxx
gateway xxx.xxx.xxx.xxx

On reboot the server is not configuring both interfaces then I did a ifconfig and noticed that both eth0 and eth1 have the same MAC address. So it seems like both interfaces are being assigned to the same NIC. I have 2 Nics in the server. Can anyone help me whats going on

  1. Find out other NIC MAC address and place it in /etc/network/interfaces

    In CentOS I could determine information about network devices in:

    /etc/udev/rules.d/70-persistent-net.rules

    I think hwinfo command might help too.
