Command Usage
•Private VLANs are used to restrict traffic to ports within the same VLAN “community,” and channel traffic passing outside the community through promiscuous ports that have been mapped to the associated “primary” VLAN.
•Port membership for private VLANs is static. Once a port has been assigned to a private VLAN, it cannot be dynamically moved to another VLAN via GVRP.
•Private VLAN ports cannot be set to trunked mode. (See “switchport mode” on page 125.)
