CentOS - Oct 2016 - C7 and WOL

Hi list,
I've encountered a problem with wol. I'm not new to this but this time I
found unwanted behaviuor.

I'm triyng to wol another c7 machine. When I run ether-wake @mac the 
system is started. When I shutdown the system after 3 seconds it start 
again and again and again.

To block this wol-loop I must disable wol on uefi or shutdown the switch.

I don't know what check.

Any suggestions?

THanks in advance
