5.5 MAC Address
The main function of the 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 switch to forward packets quickly. The entries in the
Address Table can be updated by auto-learning or configured manually. Most the entries are
generated and updated by auto-learning. In the stable networks, the static MAC address
entries can facilitate the switch to reduce broadcast packets and enhance the efficiency of
packets forwarding remarkably. The address filtering feature allows the switch to filter the
undesired packets and forbid its forwarding so as to improve the network security.
