Set Fixed MAC

If you prefer to manage IP assignments from your router instead of setting a fixed IP address, you can still set a fixed MAC address for the network interface on BMC. To do this, you need to edit the /etc/network/interfaces file in a similar way as you would for setting a fixed IP address.

Edit it to look like this:

-
# interface file auto-generated by buildroot

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
  hwaddress ether 12:34:56:78:9A:BC
  pre-up /etc/network/nfs_check
  wait-delay 15
  hostname $(hostname)

+
# interface file auto-generated by buildroot

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
  hwaddress ether 12:34:56:78:9A:BC
  pre-up /etc/network/nfs_check
  wait-delay 15
  hostname $(hostname)

This will assign a MAC address: 12:34:56:78:9A:BC to the interface. You can easily generate random MAC address for example with this one line script:

printf '%02x:%02x:%02x:%02x:%02x:%02x\n' $((0x02)) $((RANDOM%256)) $((RANDOM%256)) $((RANDOM%256)) $((RANDOM%256)) $((RANDOM%256))

But you need to make sure that the assigned MAC is not already used by any device on the network.
