• Host 2 has changed its MAC address to 00:01:02:03:04:09. The packet has an IP
address that matches the IP address in the IP/MAC Bindings table but a MAC address
that does not match the MAC address in the IP/MAC Bindings table.
• Host 3 has changed its IP address to 192.168.10.15. The packet has a MAC address that
matches the MAC address in the IP/MAC Bindings table but an IP address that does not

the traffic coming from Host 1 to any external network. The total count of dropped packets is
displayed.
