WebThis is typical for a LAN environment. When learning about Layer 2 concepts, it is helpful to analyze frame header information. In the first part of this lab, you will review the fields contained in an Ethernet II frame. In Part 2, you will use Wireshark to capture and analyze Ethernet II frame header fields for local and remote traffic. WebThe original ethernet standard also specified 14 bytes for the header, and 4 bytes for the frame check sequence. That is 18 bytes. subtract 18 from 64, and you get 46 as the minimum payload. Since then, you can add a four byte VLAN tag. So, with the VLAN tag, the minimum payload size is 42. Without the VLAN tag, the minimum payload size remains 46. how many people live in canada\u0027s core regionWebThe first part of an Ethernet frame is known as the preamble.
