One of the tagged ports is port 2 on the top switch. This port has been made a tagged member of the three VLANs. It is connected to an IEEE
It is important to note that even though the server is accepting frames from and transmitting frames to more than one VLAN, data separation and security remain.
Two other tagged ports are used to simplify network design in the example. They are port 10 on the top switch and port 9 on the lower switch. These ports have been made tagged members of the Sales and Engineering VLANs so that they can carry traffic from both VLANs, simultaneously. These ports provide a common connection that enables different parts of the same VLAN to communicate with each other while maintaining data separation between VLANs.
In comparison, the Sales and Engineering VLANs in the
