Parameters
ip: Supports IPv4 protocol. If this keyword is not provided, IPv4 is also supported.
-a source-ip: Specifies the source IP address of an ICMP echo request (ECHO-REQUEST). It must be an
IP address configured on the device. If this option is not provided, the source IP address of an ICMP echo
request is the primary IP address of the outbound interface of the request.
-c count: Specifies the number of times that an ICMP echo request is sent, which ranges from 1 to
4294967295 and defaults to 5.
-f: Discards packets larger than the MTU of a given interface, which means the ICMP echo request is not
allowed to be fragmented.
-h ttl: Specifies the TTL value for an ICMP echo request, which ranges from 1 to 255 and defaults to 255.
-i interface-type interface-number: Specifies the ICMP echo request sending interface by its type and
number. If this option is not provided, the ICMP echo request sending interface is determined by
searching the routing table or forwarding table according to the destination IP address.
-m interval: Specifies the interval (in milliseconds) to send an ICMP echo request, which ranges from 1 to
65535 and defaults to 200.
• 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 the interval argument.
• 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 the interval argument.
-n: Disables domain name resolution for the host argument. When this keyword is not provided, if the
host argument represents the host name of the destination, the device translates host into an address.
-p pad: Specifies the value of the pad field in an ICMP echo request, in hexadecimal format, 1 to 8 bits,
in the range 0 to ffffffff. If the specified value is less than 8 bits, 0s are added in front of the value to
extend it to 8 bits. For example, if pad is configured as 0x2f, then the packets are padded with
