Parameters
ip: Supports IPv4 protocol.
-a source-ip: Specifies the source IP address of an ICMP echo request. It must be a
legal IP address configured on the device.
-c count: Specifies the number of times that an ICMP echo request is sent, in the range
1 to 4294967295. The default value is 5.
-f: Discards packets larger than the MTU of a given interface, that is, the ICMP echo
request is not allowed to be fragmented.
-h ttl: Specifies the TTL value for an ICMP echo request, in the range 1 to 255. The
default value is 255.
-i interface-type interface-number: Specifies the ICMP echo request sending interface
by its type and number.
-m interval: Specifies the interval (in milliseconds) to send an ICMP echo response, in
the range 1 to 65535. The default value is 200 ms.
z If a response from the destination is received within the timeout time, the interval
to send the next echo request equals the actual response period plus the value of
interval.
z If no response from the destination is received within the timeout time, the interval
to send the next echo request equals the timeout value plus the value of interval.
-n: Specifies that the Domain Name System (DNS) is disabled. DNS is enabled by
default, that is, the hostname is translated into an address.
-p pad: Specifies the padded bytes in an ICMP echo request, in hexadecimal format.
For example, if pad is configured as ff, then the packets will be padded with ff. By
