What are the MAC flood?

MAC's profession is a method that can be used to influence safety protocols of different types of network switches. In principle, MAC floods flooding the network switch with data packets that disrupt the usual sender to the recipient data flow, which is common for MAC addresses. The final result is that rather than data moving from a particular port or sender to a particular recipient, the data is fired on all ports.

The foundations of the MAC floods begin with the corruption of the translation table, which is part of the network switch function. When the table is properly operated, the table maps each individual address of the MAC located in the network. Each MAC address is associated with the physical port on the network switch. This approach allows you to mark a specific and single point of ending the data sent in the network.

The translation table is thrown out of Kilter and the connection between Ports and specific MAC addresses are destroyed. Instead, all data are now on all network ports, toThe targets are designed for one MAC address. This means that any type of data that has been for one address will receive multiple addresses.

Part of the MAC Disruption process is to create a state where the memory capacity of the switch is quickly consumed, which is set aside for these data transmission data. If memory is no longer available for this type of transmission, it is used by spilling messages and the capacity of memory that is used for group messages is used. At the same time, logs are coming into play for group messages, allowing you to send a message to many target points.

MAC's profession can be a great way to access a variety of data, including system passwords, protected files, and EE -mail with e -mail and messaging conversations. Due to the security risk represented by the Mac flood, many switches can be configured to provide DALSecurity of specific MAC addresses, or even closed the switch if too much flood data to the port.
