Cloud Router Switch 112-8G-4S-IN is a “small size low cost” member of our CRS series. It comes with eight Gigabit Ethernet ports and four SFP cages. Our CRS series combines the best features of a fully functional router and a Layer 3 switch, is powered by the familiar RouterOS. All the specific Switch configuration options are available in a special Switch menu, but if you want, ports can be removed from the switch configuration, and used for routing purposes.
