I have a question about the Mac address learning on a switch, if a hub is connected to it. Say I have a hub(connected to Fa0/1 of switch) with two PCs, mac address table on the switch is empty. PC1 is trying to reach PC2, how does the switch learn mac address in this situation. Switch gets the ARP requests from PC1 on Fa0/1 and since there is no entry it forwards on all port except fa0/1
But here PC2 is also in Fa0/1? What happens here.
