  Network equipment configuration and management-debug Cisco Catalyst switch

  Theoretical Learning question 1: how does the switch work? By learning the MAC address of the computer associated with each interface, the data communication of each computer is realized, which is similar to the routing table of the router, and the switch is realized through the mapping table of MAC-Port. Question 2: layer 2 switch, layer 3 switch,
