4.3.0.2.1 QinQ Tunnel Setting
Virtual private networks (VPNs) provide enterprise-scale connectivity on a shared infrastructure, often Ethernet-based, with the
same security, prioritization, reliability, and manageability requirements of private networks. QinQ tunnel is a feature designed for
service providers who carry traffic of multiple customers across their networks and are required to maintain the VLAN and Layer
2 protocol configurations of each customer without impacting the traffic of other customers. When you configure QinQ tunnel,
you assign the QinQ user-port and uplink-port to a VLAN ID that is dedicated to QinQ tunnel.
To add QinQ tunnel, you first select QinQ Tunnel ID, then fill VLAN ID QinQ dedicated to QinQ tunnel, and select user-port and
uplink-port to be added to QinQ tunnel.
