first privat vlans are only possible in vtp mode transparent.
- create a primary vlan (vlan A; private-vlan primary)
- Optional you can create a isolated or community vlan and associate it with the primary (
vlan B ;private-vlan isolated or private-vlan community;
Enter primary vlan config mode and use private-vlan association [
add |

secondary_vlan_list)
To verify use:
show vlan private-vlan [type]
