If the VLAN ID of the packet is within the range of C-VLANs, the VLAN tag is replaced according to the configuration. If the VLAN ID of the packet is out of the range of C-VLAN IDs or the packet does not carry any tag, the packet is processed as follows:

If qinq vlan-translation miss-drop is used, the packet is discarded directly.

If the qinq vlan-translation miss-drop command is not used on the interface but the default VLAN ID is used, packets are tagged with the default VLAN ID before being forwarded.

In V100R002 and later versions, the implementation of VLAN mapping will be changed as follows: When an interface configured with VLAN mapping received a packet with the C-VLAN ID out of the specified range, the interface transparently transmits the packet through the normal forwarding version if the interface is added to the VLAN of the packet.
