How does one get the switch's management interface wrapped inside a QinQ?

For example, say I want all infrastructure nodes tagged VLAN 9 throughout the entire network, including the switches. However, I want each switch to have it's own QinQ to wrap those in.

Something like this:

Switch A (QinQ 100)
-- node 1 (vlan 9)
-- node 2 (vlan 9)

Switch B (QinQ 200)
-- node 3 (vlan 9)
-- node 4 (vlan 9)

so back at the router I have 2 interfaces: 100(9) for all infrastructure nodes on switch A, and 200(9) for all infrastructure nodes on switch B. (I know I can accomplish this with flat vlans, but the goal here is to have the same predictable vlan for all the field techs to work with while still keeping the network reasonably segregated).

But how to get the switch tagged vlan 9 and also wrapped inside it's designated QinQ tag? I would like switch A to be on interface 100(9) at the router along with nodes 1 and 2, and switch B to be on interface 200(9) along with nodes 3 and 4.

Thanks in advance for the feedback!

Your management vlan need to be outside of the QinQ. You could work around this by using (loosing) 2 ports, one to remove the QinQ vlan and the other one for management.

What you would need, and I'm pretty sure several WISP would find this usefull, is some kind of reverse QinQ that would encapsulate QinQ on egress an remove QinQ encapsulation on ingress.

I've never thought of that but that would be really really useful. You would need to be able to set it as a trunk port and allow a subset of vlans and then wrap an extra 0x8100 or 0x88a8 tag.

What would be the most useful is if you could wrap with a matchlist.

Selective VLANs for QinQ. Some asked for it for a long time. Chris, Dave, Stephen or Eric, can we have a features request "annoncement" where feature request would be accounted in the first post just like for SFP or compatible PoE devices ?
