Table one of Ethernet switch MAC address
UserB after receiving the message will reply message through Ethernet switch Gigabit port Ethernet
0/3 send UserA, at this point in the Ethernet switch MAC address table has been in existence UserA's
MAC address, so the message is in the form of unicast forwarding to Gigabit Ethernet 0/2 ports,
Ethernet switches at the same time will learn UserB MAC address, and the difference from the step 1is
that UserC don’t receive message that UserB sent to UserA.
