This document provides instructions for a Wireshark lab on analyzing UDP packets. Students are asked to capture UDP packets sent and received on their host, then examine the UDP header fields of one packet. They must answer questions about the number and names of UDP header fields, field lengths, the meaning of the length field, maximum payload and port numbers, the UDP protocol number, what the checksum covers, and the relationship between port numbers in request-response packets. Extra credit involves manually verifying a UDP checksum. The questions are designed to help students learn about the UDP protocol without providing explicit steps or examples.
