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
