According to 802.3-2012 (Section 3.3), each octet of a MAC frame is transmitted Least Significant Bit (LSB) first, with the exception of the FCS. Therefore, a DEST MAC of 00:00:00:00:00:02 would be transmitted on the line as 02 00 00 00 00 00 – or 0010 0000 0000 0000 0000 0000 (in Binary). Is there a way to capture the raw binary or hex bit stream as it exists on the wire? Thanks asked 24 Jul '13, 08:55  ddimarco edited 24 Jul '13, 14:20  Guy Harris ♦♦ |
One Answer:
I don't think it can be done with normal Ethernet equipment, because in my point of view the transmission is signaling technology that will not be visible on the digital side of the card and only happens "on the wire". So if you want to see how the raw bits are transferred you'll probably need to use a layer 1 analysis device that can show you what is happening on the physical wire. answered 24 Jul '13, 09:24  Jasper ♦♦ |
Makes sense, thanks for your feedback
