Configuring QinQ
Configuring Customer VLANs Using the Web Interface
Customer VLANs are configured using QinQ. QinQ tagging allows network managers to add an
additional tag to previously tagged packets. Adding additional tags to the packets helps create
more VLAN space. The added tag provides an VLAN ID to each customer, this ensures private
and segregated network traffic. The VLAN ID tag is assigned to a customer port in the service
providers network. The designated port then provides additional services to the packets with the
double-tags. This allows administrators to expand service to VLAN users.
To configure customer VLANs:
