Hi Luis,

I checked for the limitations for the Metro Ethernet 3400 and found the below limitations:

Platform Support

802.1q-tunnel-port mode: Cisco ME 3400E and ME 3400 switches.

Selective Q-in-Q (support for 1-to-2 VLAN mapping, but not 1-to-1 VLAN mapping): ME 3400E switches only.

802.1ad UNI (only C-UNI 1-to-2 mapping): ME 3400E switches only.

You can refer the below links for reference:

I didn't found any other limitations on the same.
