Step 2: Examine Ethernet frames in a Wireshark capture. Step 1: Review the Ethernet II header field descriptions and lengths. A Wireshark capture will be used to examine the contents in those fields. In Part 1, you will examine the header fields and content in an Ethernet II Frame provided to you. Part 1: Examine the Header Fields 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. In the first part of this lab, you will review the fields contained in an Ethernet II frame. When learning about Layer 2 concepts, it is helpful to analyze frame header information. 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. The frame composition is dependent on the media access type. 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. Part 2: Use Wireshark to Capture and Analyze Ethernet Frames.Part 1: Examine the Header Fields in an Ethernet II Frame.One of IPv4 Protocol Type of 1514 Byte Size Length + One of ICMP Protocol Type of 35 Byte Size Length, fragmentation is expected since Payload of 1473 is one (1) Byte larger than ICMP Max Payload size. On Wireshark, I see no fragmentation as expected. ICMP Packet: 8 Bytes Header + 1472 Bytes Max Payload.IP Packet: 20 Bytes Header + 1480 Bytes Max Payload.Ethernet Type II Frame : 1514 bytes (Wireshark does not show the last 4 bytes of CRC) = 14 Bytes Header + 1500 Bytes Max Payload.I'm trying to understand IP fragmentation for a network test and the way Wireshark displays the fragmented packets is not making much sense to me.
