How to make a permanent configuration to eth1

Question

I need to configure eth1 with:

• IP address: 10.5.15.200;
• Netmask: 255.255.255.128;
• MAC address: A2:BB:CC:DD:5:15;
• Gateway: 10.5.15.129.

Mac address must be set up before eth1 is UP. I must use pre-up but i don't know.

You can do that by configuring the /etc/network/interfaces file in Ubuntu.

Open /etc/network/interfaces file in an editor and the add these following lines

auto eth1
iface eth1 inet static
   hwaddress ether A2:BB:CC:DD:5:15
   address 10.5.15.200
   netmask 255.255.255.128
   gateway 10.5.15.129
