Configuring QinQ Mapping
QinQ mapping maps customer VLAN (C-VLAN) tags to service VLAN (S-VLAN) tags so that packets only need to be processed based on S-VLAN tags.
Pre-configuration Tasks
Before configuring QinQ mapping, complete the following tasks:
- Connect the device correctly.
- Configure the VLANs to which users belong so that user packets carry single or double VLAN tags.
- Ensure that the device is not a VCMP client.
