Users : 15 Users on LAN, 20-30 users on guest Wi-Fi, 3 Servers on LAN .
Switch which I am going to use : https://www.cisco.com/c/en/us/support/switches/sg350-28-28-port-gigabit-managed-switch/model.html
Configuration : I am planning to make five VLANS:
VLAN 10: Employees (Bandwidth limiter 10mbps).
VLAN 20: Managing Directors and their printers.
VLAN 30: CCTV Devices and NAS for storing footages.
VLAN 40: Guest WIFI which only have internet access(Bandwidth limiter 1mbps).
VLAN 50: Linux Server.
Currently we are having a 50mbps up/down plan and planning to buy a one more line of 50mbps and load balance them.
