Usage guidelines
The device sends a gratuitous ARP packet to inform other devices of its MAC address change. However, the other devices might fail to receive the packet because the device sends the gratuitous ARP packet once only by default. Use this command to configure gratuitous ARP retransmission parameters to ensure that the other devices can receive the packet.
After you execute this command, the device will retransmit a gratuitous ARP packet for its MAC address change at the specified interval for the specified times.
Examples
# Set the times to 3 and the interval to 5 seconds for retransmitting a gratuitous ARP packet for the device MAC address change.
