I am a beginner with Mikrotik and I have a CRS328-4C-20S-4S + RM that I use only as L2 switch for VLAN, with ROs 6.44.2. I'm creating VLANs, and when I have put the sfp2 ports on the bridge I've created, I lose the connection with the router. But this is only happening for the sfp2 port (I'm connected to the pc via the sfp+ port).
In the settings I have already changed the port sfp1 from WAN to LAN.
Can someone help me by telling me what I'm doing wrong?
