Principles of QinQ dual-layer tag termination performed by the N18K are as follows:

The class-id is used to identify the CE-VLAN, and the traditional VLAN is used to identify the PE-VLAN.
When a packet sent by the terminal arrives the N18K device, it carries a two-layer tag. In the host routing information internally delivered by the N18K device, the tag contains two layers, in which the outer-layer tag indicates the VLAN tag (PE-VLAN) corresponding to the L3 interface, and the inner-layer tag indicates the private VLAN tag (CE-VLAN).

Is the VLAN ID of the CE-VLAN mandatory?

For the CE-VLAN, only the CE-VLAN ID terminated by the QinQ needs to be configured. By default, the system considers that the CE-VLAN mapping is completed for the class-id.
