4.3.0.2.0 QinQ Port Setting
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.
To enable QinQ function, the global
QinQ
option, QinQ
Tpid
and specified port-based QinQ
User
or
Uplink
port option need to
be configured.
