Technical Tip: How to run a 'Fast PING' using 'adaptive-ping enable' option

[Pedro_FTNT]

Description	This article describes that it is sometimes necessary to send multiple PINGs, and multiple ICMP packages by using 'ping-options repeat-count' but it could take a long time to finish. To solve it, FortiGate has a new option named: 'adaptive-ping enable' to do a 'Fast PING'. Using this option will send the same ICMP packages more quickly.
Scope	FortiGate.
Solution	Example to use 'adaptive-ping enable' to send 50 ICMP packages: With normal ping, using 'repeat-cout': exe ping-options repeat-count 50 exe ping 8.8.8.8 64 bytes from 8.8.8.8: icmp_seq=0 ttl=58 time=5.0 ms 64 bytes from 8.8.8.8: icmp_seq=1 ttl=58 time=4.9 ms . . . 64 bytes from 8.8.8.8: icmp_seq=49 ttl=58 time=4.9 ms --- 8.8.8.8 ping statistics --- 50 packets transmitted, 50 packets received, 0% packet loss round-trip min/avg/max = 4.8/5.0/7.0 ms Using WireShark to see time: 50 seconds to complete the shipment of 50 packages: Using 'adaptive-ping enable': exe ping-options adaptive-ping enable exe ping-options repeat-count 50 exe 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=58 time=5.1 ms 64 bytes from 8.8.8.8: icmp_seq=1 ttl=58 time=4.9 ms . . . 64 bytes from 8.8.8.8: icmp_seq=49 ttl=58 time=4.9 ms --- 8.8.8.8 ping statistics --- 50 packets transmitted, 50 packets received, 0% packet loss round-trip min/avg/max = 4.8/5.0/9.9 ms 1 second to complete the shipment of the same 50 packages: To know about more options to do a PING refer to: Troubleshooting Tip: Using PING options from CLI Troubleshooting Tip: Using PING options from the FortiGate CLI
