a very simply VLAN setup I'm struggeling ATM.....
CRS106-1C-5S RouterOS 6.47.7
I Try to Setup VLAN 1337 with one tagged and one untagged port.
On Port SFP1 there should be VLAN1 and VLAN1337, on port sfp2 only VLAN1337 untagged.
All configuration is done via winbox.
I created a bridge "bridge_1337", added the port "sfp2".
I create new port "ze_1337" on port sfp1 and add it also to "bridge_1337".
Anything else I have to do? If you need more info feel free to ask, I tried to keep this post small.
