Reset ethernet and switch interface names to default

Hi,

Is there a way to quickly reset ethernet interfaces and switch group names to their default names without typing them by hand. I’ve taken over for someone who renamed the interface names of all our customers by confusing names, such as ether1 → WAN1, ether2-> WAN2, ether3 → eth1, ether4 → eth2, etc.

Is there a command similar to the “reset-mac-address” flag to reset the names to their default value?

Thanks
