-h ttl: Specifies the TTL value for an ICMP echo request. The ttl argument is in the range of 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. 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. The interval argument
is in the range of 1 to 65535. The default value is 200.
-n: Disables domain name resolution for the host argument. If the host argument represents the host name
for the destination, and this keyword is not specified, 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.The pad argument is in the range of 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 0x0000002f to make the total length of the packet meet the requirements of the device. By
default, the padded value starts from 0x01 up to 0xff, where another round starts again if necessary, like
0x010203...feff01....
-q: Displays only statistics. If this keyword is not specified, the system displays all information.
-r: Records routing information. If this keyword is not specified, routes are not recorded.
-s packet-size: Specifies length (in bytes) of an ICMP echo request (not including the IP packet header
and the ICMP packet header). The packet-size argument is in the range of 20 to 8100. The default value
is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. If the source does not
receive an ICMP echo reply within the timeout, it considers the ICMP echo reply timed out. The timeout
argument is in the range of 0 to 65535. The default value is 2000.
-tos tos: Specifies the ToS value of an ICMP echo request. The tos argument is in the range of 0 to 255.
The default value is 0.
-v: Displays non ICMP echo reply received. If this keyword is not specified, the system does not display
non ICMP echo reply.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the destination belongs, where the
vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the
public network, do not specify this option.
host: IP address or host name (a string of 1 to 253 characters) for the destination.
Usage guidelines
To use the name of the destination host to perform the ping operation, you must first configure the DNS
on the device. Otherwise, the ping operation will fail.
To abort the ping operation during the execution of the command, press Ctrl+C.
Examples
# Test whether the device with an IP address of 1.1.2.2 is reachable.
<Sysname> ping 1.1.2.2
PING 1.1.2.2 (1.1.2.2): 56 data bytes, press CTRL_C to break
56 bytes from 1.1.2.2: icmp_seq=0 ttl=254 time=2.137 ms
56 bytes from 1.1.2.2: icmp_seq=1 ttl=254 time=2.051 ms
56 bytes from 1.1.2.2: icmp_seq=2 ttl=254 time=1.996 ms
56 bytes from 1.1.2.2: icmp_seq=3 ttl=254 time=1.963 ms
