Configuring gratuitous ARP packet retransmission for the device MAC address change
About gratuitous ARP packet retransmission for the device MAC address change
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 only once by default. Configure the gratuitous ARP packet retransmission feature to ensure that the other devices can receive the packet.
