Chapter 6: VLANs
Protected Ports VLAN
You use the protected ports VLAN feature when you want to prevent ports from communicating with one another, but you want them all to have access to common resources. For example, in a hotel or apartment complex, the computer in each room or apartment needs to be isolated from one another, but they all need access to the internet or a server. This feature is called traffic segmentation. You set up traffic segmentation by selecting the ports connected to each room or apartment and identifying them as isolated ports, and then connecting one port to the WAN.
In Figure 19, the connection to the WAN is assigned to fiber port 8. This port is configured as the Primary (Ingress) port for the switch. Because it is the Primary port, it has full duplex capability to communicate with ports 1- 7R. Ports
