4.3.8 Protected Ports
Overview
When a switch port is configured to be a member of protected group (also called Private VLAN), communication between
protected ports within that group can be prevented. Two application examples are provided in this section:
 Customers connected to an ISP can be members of the protected group, but they are not allowed to communicate with
each other within that VLAN.
 Servers in a farm of web servers in a Demilitarized Zone (DMZ) are allowed to communicate with the outside world and
with database servers on the inside segment, but are not allowed to communicate with each other
