4. Assign the port to CVLANs
and SVLANs
port trunk permit vlan { vlan-id-list
| all }
Required.
By default, a trunk port is in only
VLAN 1.
5. Enable customer-side QinQ
qinq enable downlink
Required.
By default, customer-side QinQ is
disabled on all ports.
6. Apply the uplink policy to the
incoming traffic
qos apply policy policy-name
inbound
Required.
Before applying a QoS policy to the customer-side port, enable customer-side QinQ on the port. Before
disabling customer-side QinQ on the customer-side port, remove the QoS policy from the port first.

Configuring two-to-two VLAN mapping
Perform two-to-two VLAN mapping on an edge device that connects two SP networks, for example, on PE
3 in Figure 59. T
wo-to-two VLAN mapping enables two remote sites in different VLANs to communicate at
Layer 2 across two service provider networks that use different VLAN assignment schemes.
For the ease of description, the VLAN tags of the double-tagged frames that arrive at the customer-side
port are called foreign CVLANs and SVLANs, and the VLAN tags marked by the edge device are called
local CVLANs and SVLANs.
Perform these tasks to configure two-to-two VLAN mapping:
