CIS 457 Lab 5: Wireshark Network Layer


This lab should be answered individually, although of course you may discuss with classmates.


Objective: Students will gain a better understanding of IPv4 and ICMP.

What to turn in: Follow the steps in the lab, answering the questions as you go. Turn in your answers in hard copy.


To generate some traffic, we will use the ping program. This program is used to find the reachability and round trip time to a destination. Using mininet, run wireshark on h1, start a packet capture, and send a ping from h2 to h1. Take a look at an ICMP Echo reply packet.

Now, lets look at arp. The first packet in your capture should be an ARP request, followed by an ARP reply.
