Help with initial config

Hi!

New to MikroTik, but experienced in network constructs. I’ve been poking around the GUI today and not getting done what I need to. Wondering if I could ask for some assistance on basic config - gives me something to learn from!

We’re building an embedded project that will include a CRS125-24G-1S-2HnD-IN. What I need to accomplish is the following:

VLAN A has ports 1-10,21 and the switch acts as router on 172.31.5.254/23
VLAN B has ports 11-20,22 and the switch acts as router on 172.31.7.254/23
VLAN C has ports 23-24 and the WiFi and the switch acts as router on 172.27.252.4/22
VLAN D is an uplink port on port 25 (SFP). It acts as a DHCP client and runs NAT/firewall
Any vlan can route to any other VLAN or to the outside world via VLAN D

What I’m not understanding is the relations between ports, vlans, bridges, master ports, slave ports, switch1-cpu, and so forth… Some guidance to a basic config that I can learn from would be much appreciated.

Thank you!

Are the ports supposed to be tagged or untagged VLAN members? (are the devices plugged into the port VLAN aware?)

Hi, thanks for checking in. The ports will be untagged; the systems will not be aware of the VLANs, if that makes sense.
