8. Ethernet Switch (Learning) --Friday
Below is an Ethernet switch connecting Classic Ethernet segments 1, 2 and 3 of a small LAN. The column “Event” of first table lists packets that are sent on the LAN after startup. After each of these packets is sent, list which MAC addresses the switch knows are reachable on an interface, as well as which segments hear the transmission. Initially, the Switch Table is empty so it is not shown.
