The Ping-ARP plugin is designed to monitor network devices on a local and global network.
Some devices on the network do not allow ping icmp. In this case, you can try to apply this plugin.
It functions similarly to the Ping ICMP plugin, but, unlike it, it sends/receives not ICMP requests/responses, but ARP requests/responses. Since ARP packets are broadcast and do not pass through routers; this plugin can be used only within level 2 domains.
Plugin settings are not required.
