Objectives
Part 1: Examine the Header Fields in an Ethernet II Frame
Part 2: Use Wireshark to Capture and Analyze Ethernet Frames
Background / Scenario When upper layer protocols communicate with each other, data flows down the Open Systems Interconnection (OSI) layers and is encapsulated into a Layer 2 frame. The frame composition is dependent on the media access type. For example, if the upper layer protocols are TCP and IP and the media access is Ethernet, then the Layer 2 frame encapsulation will be Ethernet II. This is typical for a LAN environment.
When learning about Layer 2 concepts, it is helpful to analyze frame header information. In Part 1, 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.
