Using the ARPING Tool to Test Network Connectivity

Starting with IBM i 7.1 and via PTFs (SI31691 and its requisites) in IBM i 6.1, a tool called ARPING (Send ARP Request, SNDARPRQS) is now supported. Like its LINUX counterpart, this tool can be used to test connectivity to an IP address on a local TCP/IP network. The tool is similar to the PING (Verify TCP/IP Connection) tool, except that it uses the Address Resolution Protocol (ARP) rather than the Internet Control Message Protocol (ICMP). Unlike ICMP messages, ARP messages aren’t routable, so this command will only work for IP addresses in the local network.
