IP Ping
The IP ping utility is used to check the reachability of an IP address.

The ping command allows you to ping to a destination to see if a networked device is reachable.
Syntax
ping <destination-ip> [source-interface <interface>] count <count> interval <interval> size <size> source-ip <source-ip> ttl <ttl> tos <tos>
Command Parameters
| destination-ip | ipv4 destination address |

interface |
source interface |
count |
count of the ping packet (default 5) |
do-not-fragment |
