Port isolation
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.
