4.3.4 MAC Address
The main function of the Managed Switch is forwarding the packets to the correct ports based on the destination MAC address
of the packets. Address Table contains the port-based MAC address information, which is the base for the Managed Switch to
forward packets quickly. The entries in the Address Table can be updated by auto-learning or configured manually. Most of the
entries are generated and updated by auto-learning. In the stable networks, the static MAC address entries can facilitate the
Managed Switch to reduce broadcast packets and enhance the efficiency of packets forwarding remarkably. The address
filtering feature allows the Managed Switch to filter the undesired packets and forbid its forwarding so as to improve the network
security.
The types and the features of the MAC Address Table are listed as follows:
