Use the switchport mode private-vlan interface configuration command on the switch stack or on a
standalone switch to configure a port as a promiscuous or host private VLAN port. Use the no form of
this command to reset the mode to the appropriate default for the device.
switchport mode private-vlan {host | promiscuous}
no switchport mode private-vlan
This command is not supported on switches running the LAN base feature set.
host Configure the interface as a private-VLAN host port. Host ports belong to
private-VLAN secondary VLANs and are either community ports or isolated
ports, depending on the VLAN that they belong to.

ports are members of private-VLAN primary VLANs.
