I'm trying to set QinQ using a pair of cisco small business 300. Our ISP required the tag 2001, I  would like to send both our internal vlan 110 and 120.

When I put an interface in customer mode, I can set the vlan of the ISP, but how do I set which vlan will encapsulated ?

Usually with QinQ setups. The only thing that the customer needs to do is set up a trunk to the ISP switch. The ISP handles putting the additional VLAN tag over your tag.

That said, just set up a normal 802.1q trunk between your switch and the ISP switch.

Are they asking that your switches initiate the tunneling?

I was looking at it upside down. The port set as "customer mode" should be in our original network and the trunk port will to to our ISP switch.  I did some wireshark traces and it's OK now.

However I don't seem to be able to manage the switch in the production setup. The switch do not allow to put an ip address on either the QinQ port or on the customer mode vlan. I need to manage the switch using the console port only,

any idea for the management ?

You should have either a vlan interface for vlan 110 or 120. Which is your managment vlan? The switxh may still be using the default vlan 1 for management which would be the problem since you are not using vlan 1.
