4.6.8 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
For private VLANs to be applied, the switch must first be configured for standard VLAN operation When this is in place, one or more
of the configured VLANs can be configured as private VLANs. Ports in a private VLAN fall into one of these two groups:
Promiscuous ports
— Ports from which traffic can be forwarded to all ports in the private VLAN
— Ports which can receive traffic from all ports in the private VLAN
