Parameter
all: Enables
or disables all debugging.
timeout interval: Sets the timeout time for all debugging, in the range of 1 to
1,440 (in minutes). After the setting, all debugging is valid in the specified
period which starts from the time when the debugging is enabled. After the
period, all debugging will be disabled.

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.
Ethernet switches provide various debugging
functions for technical support specialists and senior maintenance personnel to
do network fault diagnostics.
Enabling debugging will generate a great
deal of debugging information and thus will affect the efficiency of the
system, especially after enabling all debugging through the debugging all
command, the system may collapse. Therefore, it is recommended not to use the debugging
all command. The undo debugging all command brings great convenience
for you to disable all debugging at a time instead of disabling them one by
one.

Description
Use the display diagnostic-information
command to display operation information about all or specified functional
modules.
When the system goes wrong, you need to
collect much information to locate the fault. However, each module has its
corresponding display command, which make it difficult for you to collect all
the information needed at a time. In this case, you can use display
diagnostic-information command to collect the operation information about
all or specified module. For displaying all information at a time costs a long
time and is not convenient to view, this command provides two modes for you to
collect the information
l
Output information to the Console.

-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.

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.
-r:
Specifies to record the routes. By default, the system does not record any
route.

after an ECHO-REQUEST packet is sent. The timeout argument ranges
defaults to 2,000 ms.
-tos tos:
Sets the ToS value of the 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-RESPONSE
packets). By default, except for the ECHO-RESPONSE packets, other ICMP packets
are not displayed.
ip: Chooses IP ICMP packet.
host-ip:
Domain name or IP address of the destination host, 1 to 30 characters long.
ipx: Chooses IPX packet.
ipx-address:
IPX address of the destination host.
clns:
Chooses CLNS ECHO packets.
nsap-address:
NSAP address of the destination host.
Description
Use the ping command to check the
connectivity of IP network or IPX network, and the reachability of a host.
The process of executing of the ping
command in the IP network: 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.

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 num-packet 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).
host: IP
address of the destination host or the host name of the remote system, 1 to 30
characters long.
clns: Connectionless
network service, a suit of protocols in OSI system, including CLNP, ISIS and
ESIS.
-m max-TTL: Sets a maximum TTL value. The max-TTL argument
ranges from 1 to 255 and defaults to 30.
-n
num-packet: Indicates the integral number of the
sent test packets. The num-packet argument ranges from 0 to 65535 and
defaults to 3.
-t
timeout: Sets the timeout time of the tracert
command. The timeout argument, in seconds, ranges from 0 to 65535 and
defaults to 5.
-v: Explains
the error if the response packet error occurs. If no error occurs, after you
execute the command, the result is the same as the command is executed without -v.
nsap-address:
NSAP address of the destination host.
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.

If the switch can not boot through primary and
backup boot applications, it chooses an application in the Flash randomly for
boot. If the switch still can not boot, then the switch fails to boot.
The BootROM with the version not below 400 supports
double applications boot.
Example
# Specify the S7500.APP as the primary
application adopted when the switch reboots next time.
<H3C> boot boot-loader primary
S7500.APP
