3. Set the link type of the port.
• Configure the port as a trunk port:
port link-type trunk
• Configure the port as a hybrid
port:
port link-type hybrid
By default, the link type of a
port is access.
4. Assign the port to the original
VLANs and the translated
VLANs.
• port trunk permit vlan vlan-id-list
• port hybrid vlan vlan-id-list tagged
By default, a trunk port is
assigned to only VLAN 1, and
a hybrid port is only an
untagged member of VLAN 1.
5. Configure two-to-two VLAN
mapping.
vlan mapping tunnel outer-vlan-id
inner-vlan-id translated-vlan

Network requirements
As shown in Figure 46 :
• Each home is offered PC, VoD, and VoIP services, connects to a wiring-closet switch through the
home gateway, and obtains the IP address through DHCP.
• VLAN 1 is assigned to PC traffic, VLAN 2 is assigned to VoD traffic, and VLAN 3 is assigned to VoIP
service traffic on the home gateways.
To isolate traffic of the same service type from different homes, assign one VLAN to each type of traffic
from each home on the wiring-closet switches.
