QinQ with access to management VLAN

Hi!

I have a management VLAN for my UBNT equipment (and the Netonix switch) = VLAN20
I want to have management access to equipment on PtP link (VLAN20) while also passing QinQ VLAN for 2 clients. Is that possible ?
How do I setup QinQ for that scenario ?
I have WS-26-400-AC with port 1 for client 1 and port 2 for client 2. Access Point (PtP) is on port 3. Other end has WS-6-MINI with port 3 for client 1 and port 4 for client 2 and Station (PtP) on port 5.
Any help is appreciated....

Based on your description, I don't think you need QinQ, I think you just need a few VLANs.

Let's say:
Client 1 : VLAN1001
Client 2 : VLAN1002
MGMT : VLAN20

For the WS-26-400-AC:
Port 1 for client 1 : Set VLAN1001 to T
Port 2 for client 2 : Set VLAN1002 to T
Port 3 for Access Point (PtP) : Set VLAN1001, VLAN1002, and VLAN20 to T

For the WS-6-MINI:
Port 3 for client 1 : Set VLAN1001 to T
Port 4 for client 2 : Set VLAN1002 to T
Port 5 for Access Point (PtP) : Set VLAN1001, VLAN1002, and VLAN20 to T

Then, of course, make sure your MGMT VLAN is tagged where it needs to be to get service to one of the switches.

I understand as long as they have their traffic wrapped in the QinQ VLAN tag for their system, the Netonix won't bother checking the VLAN type.

Alternatively, if you need transparent connections for the customers (where they don't add their own QinQ tag):

For the WS-26-400-AC:
Port 1 for client 1 : Set VLAN1001 to Q
Port 2 for client 2 : Set VLAN1002 to Q
Port 3 for Access Point (PtP) : Set VLAN1001, VLAN1002, and VLAN20 to T

For the WS-6-MINI:
Port 3 for client 1 : Set VLAN1001 to Q
Port 4 for client 2 : Set VLAN1002 to Q
Port 5 for Access Point (PtP) : Set VLAN1001, VLAN1002, and VLAN20 to T

I'd be interested to know how it works for you.

Clients need to be able to pass what VLAN they want, without I'm loosing access to VLAN20 (Management).

Can they do that with your example ?

I understand the second example would do that successfully. I have not actually used it in that particular configuration, though, so you should test to verify.

uberdome second answer is correct, Q for customer port and VLAN tagged or trunked between switch.
