The ping command uses the Internet control message protocol (ICMP), specifically ICMP echo request and ICMP echo reply messages.
The Ping (packet internet groper) command sends an ICMP/ICMPv6 (internet control message protocol) echo request to a host, gateway, or router and expects a reply. You can invoke the ping function using the TSO PING command or the z/OS UNIX shell ping or ping commands.
As mentioned on the previous page, an echo is simply what network engineers call a "ping". The echo reply is, as most people assume, a "ping reply". ICMP echo is primarily used for debugging.
The way the ping command works with other networking tools is by sending a special packet known as an Internet Control Message Protocol (ICMP) echo request to the target device, to which the receiving device responds with an ICMP echo reply packet. Just waiting to send it back.
