The IEEE 802.1Q trunk protocol connects two or more Ethernet or Token Ring switches, and allows transmission of packets between Switches sharing the same VLAN(s).
Principle
In figure 1 all PC's connected to ports which are in VLAN 100 - Blue - can communicate together, and all PC's connected to ports in VLAN 200 - Red - can communicate together. In figure 1 there can be no exchange of packets between VLAN 100 and VLAN 200.
