4.6.8 Port Isolation Configuration

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
create multiple spanning trees in a network, which significantly improves
network resource utilization while maintaining a loop-free environment.
