The Ethertype value appears following the Source Address field in a Version 2 Ethernet frame. This value also appears as the Type field in a Sub-Network Access Protocol (SNAP) header in SAP "AA" in Logical Link Control / 802.2. (The compendium contains discussions of Version 2 Ethernet and Logical Link Control.)The purpose for the Ethertype is to provide an identifier whereby the communications software can differentiate between various types of protocols. A different protocol handler is used for different function, and the Ethertype identifies the frame as belonging to one or another protocol family.
