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 IPv4 address, using the options configured by ping-options.
Pings are often used to test IP-layer connectivity during troubleshooting.
To use this command, your administrator account’s access control profile must have at least r
permission to the sysgrp
area. For details, see Permissions.
Syntax
execute ping {<host_fqdn> | <host_ipv4>}
Variable | Description | Default |
Type either the IPv4 address or fully qualified domain name (FQDN) of the host. | No default. |
Example
This example pings a host with the IP address 192.0.2.10
.
execute ping 192.0.2.10
The CLI displays the following:
PING 192.0.2.10 (192.0.2.10): 56 data bytes
64 bytes from 192.0.2.10: icmp_seq=0 ttl=128 time=0.5 ms
64 bytes from 192.0.2.10: icmp_seq=1 ttl=128 time=0.2 ms
64 bytes from 192.0.2.10: icmp_seq=2 ttl=128 time=0.2 ms
64 bytes from 192.0.2.10: icmp_seq=3 ttl=128 time=0.2 ms
64 bytes from 192.0.2.10: icmp_seq=4 ttl=128 time=0.2 ms
--- 192.0.2.10 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 indicate that a route exists between the FortiWeb appliance and 192.0.2.10
. It also indicates that during the sample period, there was no packet loss, and the average response time was 0.2 milliseconds.
Example
This example pings a host with the IP address 192.0.2.78
.
execute ping 192.0.2.78
The CLI displays the following:
PING 192.0.2.78 (192.0.2.78): 56 data bytes
After several seconds, no output appears. The administrator halts the ping by pressing Ctrl+C. The CLI displays the following:
--- 192.0.2.78 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss
The results indicate the host may be down, or there is no route between the FortiWeb appliance and 192.0.2.78
. To determine the point of failure along the route, further diagnostic tests are required, such as traceroute.
