When you need to repair your car, do you take the photos to the mechanic?

From the photos, how can you see how the device is configured?
Apparently everything is wrong, you have made all virtual vlans, instead of letting the bridge manage the vlans.
That's a switch, not a router (and probably is the wrong configuration also if is a router)

I think you are right.

my cfg:
bridge ports : one sfp+ port + all vlans
vlans: made in inteface/vlan on interface bonding thats all

How about this one: viewtopic.php?t=143620

Indeed it's not cookbok recipe for your particular case, you should combine a few things (but then you have to understand a few basics about how ROS works).
