Switch works is that?

1. Switches with basic learning and forwarding;
2. Learning function: When the switch receives an Ethernet frame from a port will first look at the production of the data frame source MAC address, the port number corresponding to the MAC address into the MAC table; MAC address table already exists in the MAC entry, update timer (MAC address aging time is 300S)
3. Forwarding: When the switch receives Ethernet frames from one port, the destination MAC view of the data frame, according to the MAC in MAC address entry corresponding to the forwarded through the corresponding interface; if the MAC address table is not the MAC address entry, except from the port to accept all ports flooded out.
