計網作業二(老爺偷改版)

1. Use Wireshark to analyze the packets sent from your NIC. Determine the manufacturer according to its OUI.
2. Save the frames you captures in files. Check the list of all Ethernet frame types in RFC 5342 (BCP 0141). How many different frame types did you observe in your dormitory and NCNU computer classrooms, respectively?
