Section: Switching

Explanation

Explanation/Reference:

The switch has to try to deliver the frame, but it doesn’t know in which direction the host is. In this situation, the switch sends the frame out on all ports (except the

one which received the frame) in the hope that the frame will eventually get received. If and when that host replies, the reply frame will come into the switch, and the

switch will take the (now) source MAC address of 00b0.d056.efa4 and add it to the switching table.
