Down the Rabbit Hole: A Close Look at Ethernet

You've probably used Wireshark or a similar packet sniffer to look at TCP/IP traffic and Ethernet frames at the byte level. But just how deep does the rabbit hole go? Dig down into the Ethernet physical layer with a high-bandwidth oscilloscope and see what actual Ethernet frames look like on the wire. We'll cover the 10Base-T, 100Base-TX, 1000base-X, and 10Gbase-R standards in depth with example waveforms and protocol analysis, as well as brief discussion of 1000baseT and 40Gbase-SR4 and the "killer packet" vulnerability in the 100baseTX specification.

Watch here.
