Review the captured data in Wireshark and examine the IP and MAC addresses of the three locations that you pinged. Step 2: Examining and analyzing the data from the remote hosts. You can stop capturing data by clicking the Stop Capture icon. Note the IP address received for each URL. Note: When you ping the URLs listed, notice that the Domain Name Server (DNS) translates the URL to an IP address. With the capture active, ping the following three website URLs:. 
A window prompts you to save the previously captured data before starting another capture.Step 1: Start capturing data on the interface. You will then determine what is different about this data from the data examined in Part 1. In Part 2, you will ping remote hosts (hosts not on the LAN) and examine the generated data from those pings. Part 2: Capture and Analyze Remote ICMP Data in Wireshark Note: In the preceding example of a captured ICMP request, ICMP data is encapsulated inside an IPv4 packet PDU (IPv4 header) which is then encapsulated in an Ethernet II frame PDU (Ethernet II header) for transmission on the LAN.
The MAC address is obtained through an ARP request.

How is the MAC address of the pinged PC obtained by your PC?

Click the plus sign to the left of the Ethernet II row to view the destination and source MAC addresses.ĭoes the source MAC address match your PC interface (shown in Step 1.b)? _ Yesĭoes the destination MAC address in Wireshark match your team member MAC address?
With this PDU frame still selected in the top section, navigate to the middle section. Notice that the Source column has your PC IP address, and the Destination column contains the IP address of the teammate PC that you pinged. Click the first ICMP request PDU frames in the top section of Wireshark. 
Note the IP address of your PC interface, its description, and its MAC (physical) address.ģ.4.1.2 Lab – Using Wireshark to View Network Traffic Answers 011. Open a command window, type ipconfig /all, and then press Enter. Step 1: Retrieve your PC interface addresses.įor this lab, you will need to retrieve your PC IP address and its network interface card (NIC) physical address, also called the MAC address. This analysis should help to clarify how packet headers are used to transport data to their destination. You will also look inside the frames captured for specific information. In Part 1 of this lab, you will ping another PC on the LAN and capture ICMP requests and replies in Wireshark. Part 1: Capture and Analyze Local ICMP Data in Wireshark If using a packet sniffer such as Wireshark is an issue, the Answers may wish to assign the lab as homework or perform a walk-through demonstration. It is recommended that permission be obtained before running Wireshark for this lab. Using a packet sniffer such as Wireshark may be considered a breach of the security policy of the school. Additional PCs on a local-area network (LAN) will be used to reply to ping requests.Īnswers Note: This lab assumes that the student is using a PC with internet access and can ping other PCs on the local area network. 1 PC (Windows 7, 8, or 10 with internet access). In this lab, you will use Wireshark to capture ICMP data packet IP addresses and Ethernet frame MAC addresses. Wireshark is a useful tool for anyone working with networks and can be used with most labs in the CCNA courses for data analysis and troubleshooting. As data streams travel back and forth over the network, the sniffer “captures” each protocol data unit (PDU) and can decode and analyze its content according to the appropriate RFC or other specifications.

Wireshark is a software protocol analyzer, or “packet sniffer” application, used for network troubleshooting, analysis, software and protocol development, and education.
