Gratuitous ARP
. For
this function, the NPort will actively send ARP packets to inform the devices in the network how to find the
NPort. If you enable Ethernet/Bridge mode, you can input the IP/MAC address of the legacy device that
connected to the Ethernet port of the NPort. The NPort will help to send out the ARP packets with its IP
address to inform the network how to find this legacy device.
Gratuitous ARP
Default
Enabled
Options
Enable / Disable
Description
Gratuitous ARP requests provide duplicate IP address detection. The NPort sends broadcast
packets to update ARP tables on other devices (e.g., AP, PC) periodically. We can use this
function to notify networked devices that the NPort is still alive. Moreover, the NPort can
send Gratuitous ARP for legacy devices that do not have this function.
If you want the NPort to send Gratuitous ARP for legacy devices, enter the legacy devices’
IP and Mac addresses in
IP/MAC address
field.
