Note: Selective Q-in-Q rules are only applied to single-tagged frames received on the
access ports. If the incoming frames are untagged or single-tagged but
received on a tunnel port or cannot match any selective Q-in-Q rules, the
Switch applies the port-based Q-in-Q rules to them.
Click Selective QinQ in the Advanced Application > VLAN Stacking screen to
display the screen as shown.
