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.
