private-vlan vlan-id{community primary isolated} no private-vlan vlan-id

vlan-id- ID of private VLAN. (Range: 1-4092, no leading zeroes).

community - A VLAN in which traffic is restricted to host members in the same VLAN and to promiscuous ports in the associate primary VLAN.

primary - A VLAN which can contain one or more community VLANs, and serves to channel traffic between community VLANs and other locations.

isolated – Specifies an isolated VLAN. Ports assigned to an isolated VLAN can only communicate with the promiscuous port within their own VLAN.

Default Setting

None

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 4-245.)

Example

Console(config)#vlan database

Console(config-vlan)#private-vlan 2 primary

Console(config-vlan)#private-vlan 3 community

Console(config)#

private vlan association

Use this command to associate a primary VLAN with a secondary (i.e., community) VLAN. Use the no form to remove all associations for the specified primary VLAN.
