all: Used to
disable all debugging.
Description
Use the debugging command to enable
system debugging.
Use the undo debugging command to
disable system debugging.
By default, all debugging is disabled for
the system.
Enabling debugging will generate a great
deal of debugging information and thus will affect the efficiency of the
system. Therefore, it is recommended not to enable debugging for multiple
functional modules at the same time. The undo debugging all command brings
great convenience for you to disable all debugging at a time instead of
disabling them one by one.
Related command: display debugging.

View
Any view
Parameter
-a ip-address: Sets the source IP address to send the ICMP ECHO-REQUEST packets.
-c count: Specifies how many times the ICMP ECHO-REQUEST packet will be
sent. The count argument is the times, which ranges from 1 to 4,294,967,295 and
defaults to 5.
-d: Sets the
socket to DEBUGGING mode. By default, it is non-DEBUGGING mode.
-f:
Specifies to discard a packet directly instead of fragmenting it if its length
is greater than the MTU (maximum transmission unit) of the interface.
-h ttl:
Sets the TTL (time to live) value of the ICMP ECHO-REQUEST packets in the range
of 1 to 255. By default, the TTL value is 255.
-i: Selects
the port to send the packets.
interface-type: Interface type.
interface-number: Interface number.
ip: Selects
the IP ICMP packet.
-n:
Specifies to regard the host argument as an IP address without performing
domain name resolution. By default, the host argument is first regarded as an
IP address; if it is not an IP address, domain name resolution is performed.
-p pattern: Specifies the padding byte pattern of the ICMP ECHO-REQUEST
packets. The pattern argument is a byte in hexadecimal. For example, -p ff
fills a packet with only ff. By default, the system fills a packet with 0x01,
0x02, and so on, until 0x09; then it repeats this procedure from 0x01 again.
-q: Specifies
to display only the statistics and not to display the details. By default, all
the information including the details and statistics will be displayed.
-s packetize: Specifies the size (in bytes) of each ICMP ECHO-REQUEST packet (excluding
the IP and ICMP headers). The packetize argument ranges from 20 to 32,000 and defaults
to 56 bytes.
-t
timeout: Sets the timeout time (in ms) waiting for
an ICMP ECHO-REPLY packet after an ICMP ECHO-REQUEST packet is sent. The timeout
argument ranges from 0 to 65535 and defaults to 2,000 ms.
-tos tos:
Sets the ToS value of the ICMP ECHO-REQUEST packets in the range of 0 to 255.
By default, this value is 0.
-v: Specifies
to display other ICMP packets received (that is, non-ECHO-REPLY packets) as
well as the ECHO-REPLY packets. By default, except for the ECHO-REPLY packets,
other ICMP packets are not displayed.
host: Domain
name or IP address of the destination host.
Description
Use the ping command to check the IP
network connectivity and the reachability of a host.
The executing procedure of the ping
command is as follows: First, the source host sends an ICMP ECHO-REQUEST packet
to the destination host. If the connection to the destination network is
normal, the destination host receives this packet and responds with an ICMP
ECHO-REPLY packet.
You can use the ping command to
check the network connectivity and the quality of a network line. This command
can output the following information:
l
Response status of the destination to each ICMP
ECHO-REQUEST packet. If no response packet is received within the timeout time,
including the number of bytes, packet sequence number, TTL and response time of
the response packet. If no response packet is received within the timeout time,
the message "Request time out" is displayed
instead.
l
Final statistics, including the numbers of sent
packets and received response packets, the irresponsive packet percentage, and
the minimum, average and maximum values of response time.
You can set a relatively long timeout time
waiting for response packet if the network transmission is slow.
Related command: tracert.
Example
# Check the reachability of the host with
IP address 202.38.160.244.

] [ -p port ] [ -q num-packet ] [ -w timeout
] string
View
Any view
Parameter
-a source-ip: Sets the source IP address used by this command.
-f first-ttl: Sets the initial TTL of the packets to be
sent, so that this command displays the addresses of only those gateways on the
path whose hop counts are not smaller than the hop count specified by the first-ttl
argument. For example, if the first-ttl argument is three, the command displays
the addresses of the gateways from the third hop The first-ttl argument ranges
from 1 to 255 and defaults to 1.
-m max-ttl: Sets the maximum TTL value of the packets to be sent. After the command sends a packet with the maximum TTL, it will not
send any more packets. With this argument, this command displays the addresses
of only those gateways from the source destination to the hop count specified
by the argument. For example, if the max-ttl argument is 5, the command
displays the addresses of the gateways from the source to the fifth count. The max-ttl
argument ranges from 1 to 255 and defaults to 30.
-p port: Sets the destination port of the packets to be sent. The port argument ranges from 0 to 65535 and defaults to 33434.
Generally, you need not change the argument.
-q num-packet: Sets the
number of packets to be sent every time. The nqueries argument ranges from 0 to
65,535 and defaults to 3.
-w
timeout: Sets the timeout time to wait for ICMP error
packets. The timeout argument ranges from 0 to 65,535
and defaults to 5,000 (in milliseconds).
string: IP
address of the destination host, or host name of the remote system with 1 to 20
characters.
Description
Use the tracert command to trace the
gateways the test packets passes through during its journey from the source to
the destination. This command is mainly used to check the network connectivity.
It can help you locate the trouble spot of the network.
The executing procedure of the tracert
command is as follows: First, the source sends a packet with the TTL of 1, and
the first hop device returns an ICMP error message indicating that it cannot
forward this packet because of TTL timeout. Then, the source resends a packet
with the TTL of 2, and the second hop device also returns an ICMP TTL timeout
message. This procedure goes on and on until a packet gets to the destination
or the maximum TTL is reached. During the procedure, the system records the
source address of each ICMP TTL timeout message in order to offer the path that
the packets pass through to the destination.
If you find that the network is in trouble
by using the ping command, you can use the tracert command to
find where the trouble is in the network.
The tracert command can output the
IP addresses of all the gateways the packets pass through to the destination.
It output the string "***" if a gateway times out.
Example
# Trace the gateways the packets pass
through during its journey to the destination with IP address 18.26.0.115.

ID of a switch.
Description
Use the reboot command to restart a

When rebooting, the system checks whether there is any configuration
change. If there is, it prompts you to indicate whether or not to proceed. This
prevents you from losing your original configuration due to oblivion after
system reboot.
Example
# Directly restart this switch without
saving the current configuration.
<H3C> reboot
Start to check configuration with
next startup configuration file,
please wait......
This command will reboot the device.
Current configuration may be lost in next
startup if you continue. Continue?

the specified time is earlier than the current time.
After you execute the command, the system
will prompt you to confirm. Enter "Y" or "y" for your
setting to take effect, and your setting will overwrite the old one (if
available).
If you adjust the system time by the clock
command after executing the schedule reboot at command, the schedule
reboot at command will be invalid and the scheduled reboot will not happen.
Related command: reboot, display
