SNLS614A September 2018 – December 2018 DP83869HM
When configured for Magic Packet mode, the DP83869HM scans all incoming frames addressed to the node for a specific data sequence. This sequence identifies the frame as a Magic Packet frame.
The Magic Packet should be byte aligned.
A Magic Packet frame must also meet the basic requirements for the LAN technology chosen, such as SOURCE ADDRESS, DESTINATION ADDRESS (which may be the receiving station’s IEEE address or a BROADCAST address), and CRC.
The specific Magic Packet sequence consists of 16 duplications of the IEEE address of this node, with no breaks or interruptions, followed by a SecureOn password if security is enabled. This sequence can be located anywhere within the packet, but must be preceded by a synchronization stream. The synchronization stream is defined as 6 bytes of FFh.
