We have been switching to the UBNT EP-S16 on our towers instead of running cables down to the router at the bottom. To segment things, you need to use VLANs.
This code snippet will create 16 VLANs on Port 3 of a Mikrotik with VLAN IDs of 1001-1016.
:for x from=1001 to=1016 do={/interface vlan add interface=ether3 vlan-id="$x" name="ether3.$x"}
