1. Portsecurity

Portsecurity is a feature that can limit the MAC adresses that are allowed on a physical port. A violation of the port security occurs if
  • the number if MAC adresses on a port is reached an the MAC id is different from the allowed list
  • an allowed MAC id is connected to a differnt port in the same VLAN

Port security is seen as a deterrent for people that want to connect rogue devices to your network.
