4.1.8. Magic Packets

A magic packet can be a unicast, multicast, or broadcast packet which carries a defined sequence in the payload section. Magic packets are received and acted upon only under specific conditions, typically in power-down mode.

The defined sequence is a stream of six consecutive 0xFF bytes followed by a sequence of 16 consecutive unicast MAC addresses. The unicast address is the address of the node to be awakened.

The sequence can be located anywhere in the magic packet payload and the magic packet is formed with a standard Ethernet header, optional padding and CRC.
