h
ttl
: Configures the TTL value for echo requests to be sent. The TTL value ranges
from 1 to 255. The default value is 255.
-i
:
Specifies an interface to send packets
.
interface-type
: Specifies the interface type.
interface-number
: Specifies the interface number.
-
n
: Configures to take the host parameter as IP address without domain name
resolution.
-
p
:
pattern
is the hexadecimal padding of ICMP echo-request, for example -p ff
pads the packet completely with ff. By default, the starting padding is 0x01,
crescent, and the ending padding is 0x09, and then repeat.
-q
: Configures not to display any other detailed information except statistics.
-r
: Record route. By default, the system does not record route.
-s
packetsize
: Specifies the length of ECHO-REQUEST (excluding IP and ICMP
packet header) in bytes. The length of the echo-request packet defaults to 56
bytes.
-
t
timeout
: Maximum waiting time after sending the echo-request (measured in
ms). The time defaults to 2000 ms.
-tos
tos:
Specifies TOS value for echo requests to be sent, range from 0 to 255.
The default value is 0.
-
v
: Displays other received ICMP packets (non echo-response). By default, no other
non echo-response ICMP packets is displayed.
-
vpn-instance
vpn-instance-nam
: VPN instance name.
host
: Destination host domain name or IP address of the destination host.
ip
: Chooses IP ICMP packet.
Description
Use the
ping
command to check the IP network connection and the reachability
of the host.
The
ping
command sends ICMP ECHO-REQUEST message to the destination. If
the network to the destination works well, then the destination host will send
ICMP ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST.
Perform
ping
command to troubleshoot the network connection and line quality.
The output information includes:
■
Responses to each of the ECHO-REQUEST messages. If the response message is
not received until timeout, output "Request time out". Or display response
message bytes, packet sequence number, TTL and response time.
