I have a very basic question. How does a switch port learn a MAC address? In this scenario say a host is not trying to communicate with any one. It is just plugged in the switch port. Does the host send its MAC address to the switch port, or does the switch pull the MAC address information to the switch port?
My case is, a client plugs into a switch port, but no MAC address is being learned in the switch port. What could be the possible reason?
