Configuring QinQ termination
Based on the range of outermost two layers of VLAN IDs in the VLAN-tagged packets that can be
terminated by a subinterface, QinQ termination includes the following categories:
• Unambiguous QinQ termination—Terminates packets whose outermost two layers of VLAN IDs
match the specified values and does not allow any other VLAN-tagged packet to pass through this
subinterface. When the subinterface receives a packet, it removes the two layers of VLAN tags of
the packet. When the subinterface sends out the packet, it tags the packet with two layers of VLAN
tags as specified.
