Naming Schemes Hierarchy

  • Add “net.ifnames=0” and “biosdevname=0” as kernel arguments to grub
  • In ‘/etc/sysconfig/network-scripts/’ Change your configured NIC config file to ‘ifcfg-ethX’
  • If you have multiple interfaces and want to control naming of each device rather than letting the kernel do in its own way, /etc/udev/rules.d/60-net.rules seems necessary to override /usr/lib/udev/rules.d/60-net.rules.
