Hello! I am a student of the Department of Computer Science Information Engineering. Recently, I am learing VLAN and IEEE 802.1Q protocol, and here are two questions that confused me : 1. A packet with 802.1q VLAN tag 424 is sent out from the switch via port Gi1/0/1. Later, the same packet is sent out again, but via port Gi1/0/2. What is the difference in 802.1q header between the two output packets from distinct source ports? 2. Three Packets with no 802.1q VLAN tag are sent out from different end users to the switch via ports Gi1/0/3, Gi1/0/4, Gi1/0/5, respectively. What is the difference in 802.1q header among the three packets from distinct incoming ports? Could anyone please help me figure out these problems? Thank you!
