What happens to a compromised switch during a MAC address table attack?

  • The switch interfaces will transition to error-disabled state.
  • The switch will drop all received frames.
  • The switch will flood all incoming frames to all other ports in the VLAN.
  • The switch will shut down.

Explanation: A MAC address table attack will fill the MAC address table. When the MAC address table is full, the switch treats the frame as an unknown unicast and begins to flood all incoming traffic to all ports only within the local VLAN.
