  1. Switches contain a CAM (content addressable memory) table which keeps a record of MAC addresses and the switch port they are associated with. The CAM table is a finite resource. When it is full, the switch will no longer know which port is associated with a particular MAC address and will instead be downgraded to a layer 1 network device.
    1. What happens to the network traffic when a switch is downgraded to a layer 1 device?
    2. What performance and security implications exist as a result of the above?
    3. How can this be prevented from occurring?
