5.8.3 Private VLAN configuration
Private VLAN (PVLAN) allows to perform traffic distinction on the second layer of the OSI Model
between switch ports, which located in one broadcast domain.
Three types of PVLAN ports can be configured on switches:
promiscuous – port, which can exchange data between any interfaces, including isolated and
community ports PVLAN.
isolated - port, which is completely isolated from other ports within PVLAN, except promiscous
ports. PVLAN blocks all traffic transmitting to isolated ports, except traffic from promiscuous
ports. Packets from isolated ports can be transmitted only to promiscuous ports.
community – group of ports, which can exchange data with each other and promiscuous ports .
These interfaces are separated from other community interfaces and isolated ports within PVLAN
on the second layer of the OSI Model.
The process of performing function of additional separation of ports by Private VLAN is depicted in
