Command Usage

Private VLANs are used to restrict traffic to ports within the same community or isolated VLAN, and channel traffic passing outside the community through promiscuous ports. When using community VLANs, they must be mapped to an associated “primary” VLAN that contains promiscuous ports. When using an isolated VLAN, it must be configured to contain a single promiscuous port.

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 4-199.)
