1. PC1's ARP Aging Time < SW's MAC ADD Aging Time -> PC1 sends a ARP request and SW floods that packet. 2. PC1's ARP Aging Time > SW's MAC ADD Aging Time -> PC1 sends a unicast packet. Since SW doesn't know which port to forward that packet, it (unicast) floods that packet.
Am I right? If I am right, is it a big deal whether ARP Aging Time is greater or less than MAC ADD Aging Time?
