Description
This article describes the FortiGate's ping options that can be used for various troubleshooting purposes. Particularly useful options are repeat-count and source.
Solution
From the CLI, type the following command to see all options :
FGT# execute ping-options ?
# execute ping-options adaptive-ping <enable|disable>
# execute ping-options data-size <bytes>
# execute ping-options df-bit {yes | no}
# execute ping-options pattern <2-byte_hex>
# execute ping-options repeat-count <repeats>
# execute ping-options source {auto | <source-intf_ip>}
# execute ping-options timeout <seconds>
# execute ping-options tos <service_type>
# execute ping-options ttl <hops>
# execute ping-options validate-reply {yes | no}
# execute ping-options view-settings
# execute ping-options use-sdwan <yes | no>
# execute ping-options reset
Keyword Description Default
- adaptive-ping <enable|disable> FortiGate sends next packet as soon as the last response is received.
- data-size <bytes> Specify the datagram size in bytes.
- df-bit {yes | no}Set df-bit to yes to prevent the ICMP packet from being fragmented. Set df-bit to no to allow the ICMP packet to be fragmented.
- pattern <2-byte_hex> Used to fill in the optional data buffer at the end of the ICMP packet. The size of the buffer is specified using the data_size parameter. This allows you to send out packets of different sizes for testing the effect of packet size on the connection.
- repeat-count <repeats> Specify how many times to repeat ping.
- Source {auto | <source-intf_ip>} :Specify the FortiGate interface from which to send the ping.
If auto is specified, the FortiGate selects the source address and interface based on the route to the <host-name_str> or <host_ip>.
Specifying the IP address of a FortiGate interface is used to test connections to different network segments from the specified interface.
- timeout <seconds> Specify, in seconds, how long to wait until ping times out.
- tos <service_type> Set the ToS (Type of Service) field in the packet header to provide an indication of the quality of service wanted.
- lowdelay = minimize delay.
- throughput = maximize throughput.
- reliability = maximize reliability.
- lowcost = minimize cost.
- ttl <hops> Specify the time to live. Time to live is the number of hops the ping packet should be allowed to make before being discarded or returned.
- validate-reply {yes | no} Select yes to validate reply data.
- view-settings : Display the current ping-option settings.
- use-sdwan <yes | no> - if set to yes, then ping will be following SD-WAN rules and policy routes. Usually used with other options, for example source, to match specific SD-WAN rule that as based on specific source address.
- reset - reset ping options to default values.
