802.1AD have small MTU value
802.1Q allows to me for use MTU value over 1500 on fragment and network functions normally, transperent. But in 802.1AD this value is 'jammed' on 1430 for me, I tested this with 'ping -s'
Thus, the network doesn't work between two nodes connected over ethernet. I just backed to 802.1Q in config files.
