In some situations, it is necessary to send PING tests with a time interval between each ICMP packet sent. To do it, FortiGate has a 'ping-options interval' option.
- Example using FortiGate CLI:
execute ping-options interval 10 <----- Time in seconds between each ping.
execute ping-options repeat-count 10 <----- Specify how many times to repeat the ping attempt, optional.
execute ping 8.8.8.8<----- To internet test IP.
execute ping-options interval 10
execute ping-options repeat-count 10
execute ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: icmp_seq=0 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=1 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=4 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=5 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=6 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=7 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=8 ttl=117 time=4.8 ms
64 bytes from 8.8.8.8: icmp_seq=9 ttl=117 time=4.8 ms
--- 8.8.8.8 ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 4.8/4.8/4.8 ms
Interval, ICMP each 10 seconds:
- ICMP time using sniffer in CLI, 10 seconds between each ICMP request.
- ICMP time using Wireshark capture, 10 seconds between each ICMP request.
