Enabling IP conflict notification
By default, if the sender IP address of an incoming ARP packet is the same as that of the device, the device sends a gratuitous ARP request. The device displays an error message only after it receives an ARP reply about the conflict.
You can use this command to enable the device to display error messages before sending a gratuitous ARP reply or request for conflict confirmation.
