Switches maintain a CAM Table that maps individual MAC addresses on the network to physical ports on the switch.

In MAC flooding attack, a switch is fed with many Ethernet frames, each containing different source MAC addresses, by the attacker. Switches have a limited memory for mapping various MAC addresses to physical ports.

What happens when the CAM table becomes full?

A.
Switch then acts as hub by broadcasting packets to all machines on the network

B.
The CAM overflow table will cause the switch to crash causing Denial of Service

C.
The switch replaces outgoing frame switch factory default MAC address of FF:FF:FF:FF:FF:FF

D.
Every packet is dropped and the switch sends out SNMP alerts to the IDS port
