	vpn-instance-name ] * remote-system
View	Any view
Parameter	ip: Supports IPv4 protocol.
	-asource-ip: Specifies the source IP address of an ICMP echo request. It must be a
	legal IP address configured on the device.
	-ccount: 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.
	-httl: Specifies the TTL value for an ICMP echo request, in the range 1 to 255. The
	default value is 255.
	-iinterface-typeinterface-number: Specifies the ICMP echo request sending
	interface by its type and number.
	-minterval: Specifies the interval (in milliseconds) to send an ICMP echo response,
	in the range 1 to 65535. The default value is 200 ms.
	■ 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.
	■ 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.
	-ppad: 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 default, the padded bytes start from 0x01 up to 0xff where another
	round starts again if necessary.
