Understanding How Ping Works

You can use IP ping to test connectivity to remote hosts. If you attempt to ping a host in a different IP
subnetwork, you must define a static route to the network or configure a router to route between those
subnets.
The ping command is configurable from normal executive and privileged executive mode. In normal
executive mode, the ping command supports the -s parameter, which allows you to specify the packet
size and packet count. In privileged executive mode, the ping command allows you to specify the packet
size, packet count, and the wait time.
