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 18, 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 1-7R are configured to be isolated from one another, and
therefore cannot communicate with one another.
