How can I configure selective QinQ on CE switches

Selective QinQ is also called VLAN stacking. It adds different outer tags to the frames received on a Layer 2 QinQ interface according to different inner tags or the frames matching traffic classification rules. This function enables refined management of users and services. # Configure selective QinQ on 10GE1/0/1 and add VLAN 100 in the outer tag to the tagged frames with the VLAN range of 10 to 13.

Description: - Selective QinQ can be enabled only on hybrid and trunk interfaces and applied to incoming packets. - The outer VLAN ID must exist and the interface must be added to the stack VLAN in untagged mode. - If the port vlan-stacking command with VLAN ranges specified has been executed for three or more times and VLAN ranges are combined twice at least, the configuration of each command must be committed. Otherwise, packets may be lost. For example, when port vlan-stacking vlan 30 to 60 stack-vlan 100, port vlan-stacking vlan 20 to 30 stack-vlan 100, and port vlan-stacking vlan 60 to 70 stack-vlan 100 commands are executed, VLAN ranges 20 to 60 and 20 to 70 are combined twice. Therefore, commit each command configuration.
