Packet dropped due to failed DEJA_VU Check on Gi0/2
This is an example of the output when the packet coming in on Gigabit Ethernet port 1 in VLAN 5 is
sent to an address already learned on the VLAN on another port. It should be forwarded from the port
on which the address was learned.

This is an example of the output when the packet coming in on Gigabit Ethernet port 1 in VLAN 5 has
a destination MAC address set to the router MAC address in VLAN 5 and the destination IP address
unknown. Because there is no default route set, the packet should be dropped.
