Private VLAN Association Fields

Field	Description
Primary VLAN	The VLAN ID of each VLAN configured as a primary VLAN.
Isolated VLAN	The VLAN ID of the isolated VLAN associated with the primary VLAN. If the field is blank, no isolated VLAN has been associated with the primary VLAN. An isolated VLAN is a secondary VLAN that carries traffic from isolated ports to promiscuous ports. Only one isolated VLAN can be configured per private VLAN.
Community VLAN	The VLAN ID of each community VLAN associated with the primary VLAN. If the field is blank, no community VLANs have been associated with the primary VLAN. A community VLAN is a secondary VLAN that forwards traffic between ports that belong to the same community and to the promiscuous ports. Multiple community VLANs can be configured per private VLAN.

After you click Edit, the Edit Private VLAN Association window opens and allows you to create associations with the selected primary VLAN. The following information describes the field in this window.

Secondary VLAN – The isolated or community VLANs that can be associated with the primary VLAN. Secondary VLANs that are already associated with a primary VLAN do not appear in the list and cannot be associated with another primary VLAN. To select multiple secondary VLANs, Ctrl + click each VLAN to associate with the primary VLAN.
