4. Select the PVLAN mode.
INTERFACE mode
switchport mode private-vlan {host | promiscuous | trunk}
• host (isolated or community VLAN port)
• promiscuous (intra-VLAN communication port)
• trunk (inter-switch PVLAN hub port)
Example of the switchport mode private-vlan Command
For interface details, refer to Enabling a Physical Interface in the Interfaces chapter.
NOTE: You cannot add interfaces that are configured as PVLAN ports to regular VLANs. Conversely,
you cannot add “regular” ports (ports not configured as PVLAN ports) to PVLANs.
The example below shows the switchport mode private-vlan command on a port and on a port
channel.

Creating a Primary VLAN
A primary VLAN is a port-based VLAN that is specifically enabled as a primary VLAN to contain the
promiscuous ports and PVLAN trunk ports for the private VLAN.
A primary VLAN also contains a mapping to secondary VLANs, which are comprised of community VLANs
and isolated VLANs.
1. Access INTERFACE VLAN mode for the VLAN to which you want to assign the PVLAN interfaces.
CONFIGURATION mode
interface vlan vlan-id
2. Enable the VLAN.
INTERFACE VLAN mode
no shutdown
3. Set the PVLAN mode of the selected VLAN to primary.
INTERFACE VLAN mode
private-vlan mode primary
4. Map secondary VLANs to the selected primary VLAN.
