-h ttl
: Specifies the TTL value of ICMP echo requests. The value range is 1 to 255, and the default
is 255.
-i interface-type interface-number
: Specifies the source interface for ICMP echo
requests. If you do not specify this option, the system uses the primary IP address of the matching
route's egress interface as the source interface for ICMP echo requests.
-m interval
: Specifies the interval (in milliseconds) to send ICMP echo requests. The value range
is 1 to 65535, and the default is 200.
-n
: Disables domain name resolution for the
host
argument. If the
host
argument represents the
host name of the destination, and if 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, such as 0x010203…feff01….
-q
: Displays only the summary statistics. If this keyword is not specified, the system displays all the
ping statistics.
-r
: Records the addresses of the hops (up to 9) the ICMP echo requests passed. If this keyword is
not specified, the addresses of the hops that the ICMP echo requests passed are not recorded.
-s packet-size
: Specifies the length (in bytes) of ICMP echo requests (excluding the IP packet
header and the ICMP packet header). The value range is 20 to 9600, and the default is 56.
-t timeout
: Specifies the timeout time (in milliseconds) of an ICMP echo reply. The value range is
0 to 65535, and the default is 2000. If the source does not receive an ICMP echo reply within the
timeout, it considers the ICMP echo reply timed out.
-tos tos : Specifies the ToS value of ICMP echo requests. The value range is 0 to 255, and the
default is 0.
-v : Displays non-ICMP echo reply packets. If this keyword is not specified, the system does not
display non-ICMP echo reply packets.
-vpn-instance vpn-instance-name : Specifies an MPLS L3VPN instance to which the
destination belongs. The
vpn-instance-name
argument represents the VPN instance name, a
case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify
this option.
host
: Specifies the IP address or host name of the destination. The host name is a case-insensitive
string of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-),
underscore (_), and dot (.).
Usage guidelines
To ping a device identified by its host name, configure the DNS settings on the device first. If the DNS
settings are not configured, the ping operation fails.
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
