Location is not present, then is broadcast to all ports, after receiving the response of port, the new address of exchange opportunity " study ", and handle
It is added into its internal mac address table.By this filtering of interchanger and retransmission method, it is effectively isolated broadcast wind
Cruelly, reduce the appearance of erroneous packets.
The specific workflow of flame proof multi-layer switches is as follows: first when interchanger receives a data packet from some port
First read the source MAC in packet header；It goes to read the target MAC (Media Access Control) address in packet header again, and searches corresponding end in address table
Mouthful；As there is port corresponding with this target MAC (Media Access Control) address in table, data packet is copied directly on this port；As can not find in table
Corresponding port is then on data packet broadcast to all of the port, and when purpose machine responds source machine, interchanger can be learned again
It is corresponding with which port to practise target MAC (Media Access Control) address, is no longer needed for broadcasting all of the port when transmitting data next time.
