4.6.6 Port Isolation

Overview

When a VLAN is configured to be a private VLAN, communication between ports within that VLAN can be prevented. Two

application examples are provided in this section:

 Customers connected to an ISP can be members of the same VLAN, 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
