Configuring Network VLAN Ports for VLAN Translation
  
  
    When subscriber VLAN traffic exits a network VLAN
      port, it can be untagged, tagged (with the subscriber VLAN tag), or translated (to the network
      VLAN tag).

Note   
All traffic that exits a subscriber VLAN
      port uses the subscriber VLAN tag, unless the port is configured as untagged. There is no need
      to configure VLAN translation (from network to subscriber VLAN tag) on subscriber VLAN
      ports.
      - 
        To configure network VLAN ports for VLAN translation,
use the following command and specify the network VLAN and port
numbers:
        configure {vlan} vlan_name | vlan_list
            add
            ports
            port_list
            private-vlan
            translated
           
- 
        If you want to later reconfigure a port that is configured
          for VLAN translation so that it does not translate tags, use the following command and
          specify either the tagged or the untagged
          option:
        configure
              {vlan} vlan_name | vlan_list
            add
            ports [port_list | all] {tagged | untagged} {{stpd} stpd_name} {dot1d | emistp | pvst-plus}}
