L2 SWITCHING DATABASE
VLAN & PVID Perspective
There are three types of private VLAN ports: promiscuous, isolated, and
community.
1. A promiscuous port communicates with all other private VLAN ports and is
the port you use to communicate with routers, servers, and administrative
workstations.
2. An isolated port has complete Layer 2 separation from other ports within
the same private VLAN with the exception of the promiscuous port.
3. Community ports communicate among themselves and with their
promiscuous ports. These ports are isolated at Layer 2 from all other ports
in other communities or isolated ports within their private VLAN.
4. Primary VLAN conveys incoming traffic from the promiscuous port to all
other promiscuous, isolated, and community ports.
5. Isolated VLAN used by isolated ports to communicate to the promiscuous
ports.
6. Community VLAN used by a group of community ports to communicate
among themselves and transmit traffic to outside the group via the
designated promiscuous port.
