QinQ
QinQ provides isolation between service provider networks and customers'
networks. The switch is a provider bridge that supports port-based c-tagged
service interface.
With QinQ, the switch adds an ID tag known as Service Tag (S-tag) to forward
traffic over the network. The S-tag is used to segregate traffic between various
customers, while preserving the customer VLAN tags.
Customer traffic is encapsulated with an S-tag with TPID 0x8100, regardless of
whether it was originally c-tagged or untagged. The S-tag allows this traffic to be
treated as an aggregate within a provider bridge network, where the bridging is
based on the S-tag VID (S-VID) only.
The S-Tag is preserved while traffic is forwarded through the network service
provider's infrastructure, and is later removed by an egress device.
An additional benefit of QinQ is that there is no need to configure customers' edge
devices.
QinQ is enabled in the VLAN Management > Interface Settings page.
