ping
Use this command to perform an ICMP ECHO request (also called a ping) to a host by specifying its fully qualified domain name (FQDN) or IP address, using the options configured by ping-option.
Pings are often used to test connectivity.

Example
This example pings a host with the IP address 172.16.1.10.
execute ping 172.16.1.10
The CLI displays the following:
PING 172.16.1.10 (172.16.1.10): 56 data bytes
64 bytes from 172.16.1.10: icmp_seq=0 ttl=128 time=0.5 ms
64 bytes from 172.16.1.10: icmp_seq=1 ttl=128 time=0.2 ms
64 bytes from 172.16.1.10: icmp_seq=2 ttl=128 time=0.2 ms
64 bytes from 172.16.1.10: icmp_seq=3 ttl=128 time=0.2 ms
64 bytes from 172.16.1.10: icmp_seq=4 ttl=128 time=0.2 ms
--- 172.16.1.10 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 0.2/0.2/0.5 ms
The results of the ping indicate that a route exists between the FortiMail unit and 172.16.1.10. It also indicates that during the sample period, there was no packet loss, and the average response time was 0.2 milliseconds (ms).
Example
This example pings a host with the IP address 10.0.0.1.
execute ping 10.0.0.1
The CLI displays the following:
PING 10.0.0.1 (10.0.0.1): 56 data bytes
After several seconds, no output has been displayed. The administrator halts the ping by pressing Ctrl + C. The CLI displays the following:
--- 10.0.0.1 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss
The results of the ping indicate that the host may be down, or that there is no route between the FortiMail unit and 10.0.0.1. To determine the cause, further diagnostic tests are required, such as traceroute.
