816 * This command sends an ICMP ECHO_REQUEST to network hosts. The address
817 * can be an IPv4 or IPv6 address (or both at the same time).
821 * Example of how ping an IPv4 address:
822 * @cliexstart{ping 172.16.1.2 source GigabitEthernet2/0/0 repeat 2}
823 * 64 bytes from 172.16.1.2: icmp_seq=1 ttl=64 time=.1090 ms
