4.3.3.7 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
The "Delete" button can be used to undo the addition of new Private VLANs.
: Click to add new VLAN.
