SA—Source Address
The SA field is the source address field of the ISL packet. The field should be set to the “802.3” MAC address of the switch port that transmits the frame. It is a 48-bit value.(=6bytes) The receiving device may ignore the SA field of the frame.
DA—Destination Address
The DA field of the ISL packet is a 40-bit destination address. This address is a multicast address and is set at “0x01-00-0C-00-00” or “0x03-00-0c-00-00”. The first 40 bits (=5bytes)of the DA field signal the receiver that the packet is in ISL format.
