Enabling IP conflict notification
If the sender IP address of a received gratuitous ARP packet is being used by the receiving device, by default, the receiving device sends a gratuitous ARP request, and it displays an error message after it receives an ARP reply. The receiving device repeats the default processing 5 seconds after displaying the error message, and it stops the processing when the conflict is resolved.
You can use this command to enable the device to display error message without sending any gratuitous ARP request for conflict confirmation. The receiving device displays the message every 30 seconds until the conflict is resolved.
