Howdy, I have a quick questioning that I can not seem to find an answer to.
If I have a UNI port that is configured for dot1q tunneling, and the other side of the circuit is not, what happens to the layer 2 protocol packets? If L2P packets get encapsulated when do they get de-encapsulated if the tunneling command is not on the remote end? Do they just get dropped?

This question might be better to post in the Cisco Support Community. I see there is some discussion going on over there about Layer 3 Protocols. Not sure it this is relevant to you, but it might be a good place to start.
