VLAN Management

Regular VLANs

With QinQ, the device 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 enables 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.
