8.5.1MAC Address Binding

8.5.1.1Introduction to MAC Address Binding

Most switches support MAC address learning, allowing each port to dynamically learn several MAC addresses so that forwarding data streams between known MAC addresses within the ports can be achieved. If a MAC address has aged, the packet destined for that entry will be broadcasted. In other words, a MAC address learned in a port will be used for forwarding in that port, and if the connection has been changed to another port, the switch will learn the MAC address again to forward data in the new port.

However, in some cases, security or management policy may require MAC addresses to be bound with the ports, only data streams from the bound MAC are allowed to be forwarded in the ports. That is to say, after a MAC address is bound to a port, only the data streams destined for that MAC address can flow in from the binding port, data stream destined for the other MAC addresses that are not bound to the port will not be allowed to pass through the port.
