My network uses a Unifi Dream Machine and implements VLANs. I needed a managed switch for some Ethernet devices and I had a Mikrotik Cloud Router Switch CRS125-24G from a few years ago. Previously I never used it for VLANs, and there’s no guide on how to do this except for a video on YouTube: “How To Configure Mikrotik Cloud Router Switch VLAN’s CRS1xx…” – the good news is that it the UDM and Mikrotik seems to work together.
Hope it helps if you’ve got one of these switches.
