Simple DVLAN / QinQ Setup

Hi,

I have the following relatively simple setup at the moment, mostly configured via the GUI:

* Dell PowerConnect 6248 (current f/w 3.2.0.7, which will be upgraded)
** Ports 1/g1-1/g44 (RJ45) configured as Access Ports, PVID 10.  Connected to these ports are local non-VLAN aware devices.
** Port 1/g46 (SFP) configured as Trunk Port (PVID 8; VIDs 10), reserved for the following

The trunk configuration is for an upcoming connection to another network switch over our provider's infrastructure, where it is passed over a fiber network to a remote office, which is also running networking equipment on VID 10.

The VLAN ID we have been given for the S-TAG is 66.  Their equipment on the remote end will strip the outer VLAN tag, so only VID 10 should be passed through and handled by the remote switch.

So, I assume an example frame egress Port 1/g46 to the provider network should ultimately look like:

[Dest_MAC][Src_MAC][TPID=0x88a8,VID=66][TPID=0x8100,VID=10][...]

and should strip the outer [TPID=0x88a8,VID=66] tag on ingress.

How configuration would I need to accomplish this?

Thanks in advance.
