A.3. Enabling and Disabling the Feature

To disable the consistent network device naming on Dell systems that would normally have it on by default, pass the following option on the boot command line, both during and after installation:
biosdevname=0
To enable this feature on other system types that meet the minimum requirements (see Section A.2, “System Requirements”), pass the following option on the boot command line, both during and after installation:
biosdevname=1
Unless the system meets the minimum requirements, this option will be ignored and the system will boot with the traditional network interface name format.
If the biosdevname install option is specified, it must remain as a boot option for the lifetime of the system.
