default, the padded bytes start from 0x01 up to 0x09, where another round starts again
if necessary.
-q: Presence of this parameter indicates that only statistics are displayed. By default, all
information is displayed.
-r: Records routes. By default, routes are not recorded.
-s packet-size: Specifies length (in bytes) of an ICMP echo request, in the range 20 to
8100. The default value is 56.
-t timeout: Specifies the timeout value (in milliseconds) of an ICMP echo request, in the
range 0 to 65535. It defaults to 2000.
-tos tos: Specifies type of service (ToS) of an echo request, in the range 0 to 255. The
default value is 0.
-v: Displays non ICMP echo reply received. By default, the system does not display non
ICMP echo reply.
remote-system: IP address or host name (a string of 1 to 20 characters) of the
destination device.
Description
Use the ping command to verify whether the destination device in an IP network is
reachable, and to display the related statistics.
Note that:
z You must use the command in the form of ping ip ip instead of ping ip if the
destination name is a key word, such as ip.
z Only the directly connected segment address can be pinged if the outgoing
interface is specified with the -i argument.
Examples
# Check whether the device with an IP address of 10.1.1.5 is reachable.
<Sysname> ping 10.1.1.5
PING 10.1.1.5 : 56 data bytes, press CTRL_C to break
Reply from 10.1.1.5 : bytes=56 Sequence=1 ttl=255 time = 1 ms
