Q in Q

The Q in Q scenario is attached.

My Query is

- WHat is the tunnel port VLAN ID? Is it a native VLAN ID or what ?

It's the VLAN assigned to the port configured for QinQ tunneling.

From the service provider's perspective, that's the VLAN they have assigned to that particular customer. The customer is unaware of the VLAN number and really doesn't care....because that interface just provides a 'tunnel' to the customer's other site (if the customer has one) where that that switchport will also have that same VLAN assigned to a port facing the customer's equipment.

Thanks.

I am reading the cisco documentation and understood that customer switch port will be configured for trunk port and service provider switch port will be configured for tunnel access vlan ID.

My understanding is,
In service provider switch all the inner vlan IDs tagged with outer vlan ID. For which port needs to do this configuration.


Also what is the configuration is required for the uplink port of service provider switch.
