Configures IEEE 802.1Q tunneling (QinQ) for a client access port to segregate 

and preserve customer VLAN IDs for traffic crossing the service provider 

network. 

 

 

Business customers of service providers often have specific requirements for VLAN IDs and the number of VLANs to be 

supported. The VLAN ranges required by different customers in the same service-provider network might overlap, and 

traffic of customers through the infrastructure might be mixed. Assigning a unique range of VLAN IDs to each customer 

would restrict customer configurations and could easily exceed the VLAN limit (4096) of the IEEE 802.1Q specification. 

Using the QinQ feature, service providers can use a single VLAN to support customers who have multiple VLANs. 

Customer VLAN IDs are preserved, and traffic from different customers is segregated within the service-provider network, 

even when they appear to be in the same VLAN. Using QinQ expands VLAN space by using a VLAN-in-VLAN hierarchy 

and retagging the tagged packets. A port configured to support QinQ is called a QinQ user-port. A port configured to support 

QinQ Uplink is called a QinQ uplink-port.
