Instructor Note: This lab assumes that the student is using a PC with internet access and can ping other PCs on the local area network. Additional PCs on a local-area network (LAN) will be used to reply to ping requests.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.
