Go to Simulation mode. In the Event List Filters, enable only ICMP and ARP. Using the “Simple PDU”, issue a ping from PC0 to PC1. Play the simulation. Pay close attention to how the hub processes the ICMP and ARP packets. After that, once again, use ”Add Simple PDU” to issue a ping from PC1 to PC0. Play the simulation again. How has the behavior of the hub changed from the first and second ping attempts, if at all?
