QinQ

[jjonsson]

Is is correct understood that QinQ is a way to allow VLAN in VLAN ?

So if I have this setup:

Customer <-> Wireless link <-> Netonix sw1 <-> Wireless link <-> Netonix sw2 <-> Wireless link <-> Customer

and on port customer is on in switch sw1 and sw2 I have Q on port f.ex. on VLAN100, then customer can send all VLANs he wants through the link ?
Do I need to set a MTU size on ports ?

That it, VLAN over VLANs. You need 4 additionnal bites in the MTU by "Q" overhead since you can stack more than 2 VLANs.
