Usage guidelines

By default, the device performs the following operations if it is using the sender IP address of a received ARP packet:

• Sends a gratuitous ARP request.

• Displays an error message after the device 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.
