Syntax Description
-s (Optional) Keyword to cause ping to send one datagram per second, printing one line of output for every response received. host IP address or IP alias of the host. packet_size (Optional) Number of bytes in a packet, from 56 to 1472 bytes. packet_count (Optional) Number of packets to send.

The actual packet size will be 8 bytes larger than the size you specify because the switch adds header information.
The ping command returns output only when a response is received.
Examples
This example shows how to ping a host with IP alias elvis a single time:
Console> ping elvis elvis is alive Console>
This example shows how to ping a host with IP alias elvis once per second until you press Ctrl-C to stop pinging:
Console> ping -s elvis ping elvis: 56 data bytes 64 bytes from elvis: icmp_seq=0. time=11 ms 64 bytes from elvis: icmp_seq=1. time=8 ms 64 bytes from elvis: icmp_seq=2. time=8 ms 64 bytes from elvis: icmp_seq=3. time=7 ms 64 bytes from elvis: icmp_seq=4. time=11 ms 64 bytes from elvis: icmp_seq=5. time=7 ms 64 bytes from elvis: icmp_seq=6. time=7 ms ^C ----elvis PING Statistics---- 7 packets transmitted, 7 packets received, 0% packet loss round-trip (ms) min/avg/max = 7/8/11 Console>
