2.3 MAC Table Configuration
In order to quickly forward message, Switch needs to maintain MAC address table. The
MAC address table includes the MAC address of device connected with Switch and the
interface number of Switch connected with the device. The dynamic item (not configured
manually) in the MAC address table is learned by Switch. The method of Switch learning
MAC address is as the following. If one port (supposed to be portA) receives a data frame,
Switch will analyze the source MAC address of this data frame (supposed to be MAC-
SOURCE) and consider that the message with the destination MAC address of MAC-
SOURCE can be forwarded by portA. If MAC-SOURCE has been existed in the MAC
address table, Switch will update the corresponding table. If MAC-SOURCE has not been
