We have several floor in our company, with main office and several department sitting on different floor.
Should I need to use L3 switch for each office in different floor or simply use L2 , supposing each floor will be a separate VLAN ?
My design is that main switch will be built with different VLAN (to represent each floor) and bind to different port connecting to the switch is different layer. Packet going or leaving the port will be tagged with the correspoinding VLAN. There is not need to use trunk port. Am I correct ?
What's the best way to connect different floor to the main switch, CAT5 or fibre ?
