Hi,
I want to achieve a setup below
A switch port will do qnq - for example vlan 1-4, these four vlans will be double tagged because qnq. Let's say inner vlan is 1, 2 3 or 4 and outer vlan is 100.
But vlan 5 is an exception. I do not want to apply qnq at all for this valn. This vlan will be allowed upstream without applying outer vlan tag. Only one tag which is vlan 5.
All this will be configured over one switch port.
Other vendor call this implementation qnq transparent vlan.

Does Cisco have anything similar to this?
