•  On a port with basic QinQ enabled, you must configure the port to allow packets from its PVID to 
pass through. On a port with selective QinQ enab led, you must configure the port to allow packets 
from the inner and outer VLANs of QinQ packets to pass through. 
Complete the follows tasks to configure QinQ:

Configuring basic QinQ 
Enabling basic QinQ 
A basic QinQ-enabled port tags an incoming packet with its PVID tag.  
To enable basic QinQ:  
 
Step Command  Remarks 
1.  Enter system view. 
system-view N/A 
2.  Enter interface 
view or port group 
view.  
• Enter Layer 2 Ethernet interface view or Layer 2 
aggregate interface view: 
interface interface-type interface-number 
• Enter port group view: 
port-group manual  port-group-name Use either command. 
3.
  Enable basic 
QinQ.   qinq enable 
Disabled by default.
 
 
Configuring VLAN transparent transmission 
When basic QinQ is enabled on a port, all packets passing through the port are tagged with the port’s 
PVID tag. However, by configuring the VLAN transparent transmission function on a port, you can specify 
the port not to add its PVID tag to packets carrying specific inner VL AN tags when they pass through it, 
so that these packets are transmitted in the  service provider network with single tags.  
Configuration restrictions and guidelines 
•  When you are configuring transparent transmission for a VLAN, you must configure all the devices 
on the transmission path to permit packets of this VLAN to pass through.

•  For VLANs whose packets are to be transparentl y transmitted through a port, do not configure 
VLAN mapping for them on the port. For mo re information about VLAN mapping, see Configuring 
VL

AN mapping (available only on the 5500 EI) . 
Configuration procedure 
To configure VLAN transparent transmission:  
Step Command  Remarks 
1.  Enter system view. 
system-view N/A 
2.  Enter interface view or port 
group view.  
• Enter Layer 2 Ethernet interface view 
or Layer 2 aggregate interface view: 
interface interface-type

• Enter port group view: 
port-group manual  port-group-name Use either command. 
3.
  Configure the link type of 
the ports.  port link-type
 { hybrid | trunk  }  N/A 
4.  Configure the ports to allow 
packets from the 
transparent VLANs, and 
inner and outer VLANs of 
QinQ packets to pass 
through. • When the ports are hybrid ports: 
port hybrid  vlan  vlan-id-list  { tagged  | 
untagged  } 
• When the ports are trunk ports: 
port trunk permit vlan  { vlan-id-list | 
all  }  Use either command. 
5.
  Enable basic QinQ on the 
ports.  qinq enable
  By default, basic QinQ is 
disabled on ports.  
6.
  Configure VLAN 
transparent transmission on 
the ports.   qinq transparent-vlan 
vlan-list  By default, VLAN transparent 
transmission is not configured.
 
Configuring selective QinQ 
Configuring an outer VLAN tagging policy 
Basic QinQ can only tag received frames with the PVID tag of the receiving port. Selective QinQ allows 
adding different outer VLAN tags ba
sed on different inner VLAN tags. 
You can configure an outer VLAN tagging po licy in one of the following approaches: 
•   Port-based approach 
•   QoS policy-based approach (available only on the 5500 EI) 
If multiple outer VLAN tagging policies are configured  in both approaches on the same port, the one in 
the QoS policy-based approach takes effect. 
Configuring an outer VLAN tagging policy in the port-based approach 
Before enabling selective QinQ on a port, enable basi c QinQ on the port first. When both features are 
enabled on the port, frames that meet the selective  QinQ condition are handled with selective QinQ on 
this port first, and the left frames are handled with basic QinQ.  
To configure an outer VLAN tagging policy in the port-based approach:

3.  Enable basic QinQ. 
qinq enable Disabled  by default. 
4.  Enter QinQ view and

receiving port.

NOTE: 
•  An inner VLAN tag corresponds to only one outer VLAN tag.  
•   To  c h a n
ge an outer VLAN tag, you must delete the old outer VLAN tag configuration and configure a
new outer VLAN tag.  
 
Configuring an outer VLAN tagging policy in the QoS policy-based approach (available only on the 
5500 EI) 
To enable the switch to tag tagged packets based on inner VLAN tags, follow these steps:  
•   Configure a class to match packets with certain tags. 
•   Configure a traffic behavior to tag packets with an outer VLAN tag. 
•   Create a QoS policy and associate the class with the behavior in the policy. 
•   Apply the QoS policy to the port that connects to the user.  
To configure selective QinQ:

NOTE: 
Selective QinQ has hi
gher priority than basic QinQ. A received frame is tagged with an outer VLAN ID
based on basic QinQ only after it fails to match the match criteria defined  in the traffic class.  
 
Configuring an inner-outer VLAN 802.1p priority mapping 
Through QoS policies, the 5500 SI&5500 EI switches achieve the following inner-outer VLAN 802.1p 
priority mapping modes: 
•  Marking the 802.1p priorities in outer VLAN tags according to the inner VLAN IDs or the 802.1p 
priorities in the inner VLAN tags. 
•   Copying the 802.1p priority in the inner VLAN tags to the outer VLAN tags.

Configuring inner VLAN ID substitution (available only on the 
5500 EI) 
When you configure basic QinQ or an outer VLAN tagging policy for selective QinQ on a port 
connecting the device to the customer network, basi c QinQ or the outer VLAN tagging policy can add 
outer VLAN tags to packets, but cannot modify the inner VLAN IDs of packets.  
To modify the inner VLAN IDs of packets, follow these steps on the port connecting the device to the 
service provider network: 
1.  Configure a class to match th e specified inner VLAN IDs an d outer VLAN ID of packets. 
2. Configure a behavior to modify  the inner VLAN IDs of packets.  
3. Associate the class with the behavior in a QoS policy.  
4. Apply the QoS policy to the outgoing traffic of  the port connecting the device to the service 
provider network.
