View
User view
Parameters
module-name: Module name.
debugging-option: Debugging option.
all: Specifies 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.
Note that:
zEnabled 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 functions at the same time. To disable all debugging at a
time, you can use the undo debugging all command.
zThe specific debugging information can be displayed on a terminal only after you
have configured the debugging, terminal debugging, and terminal monitor
commands.
zTo display the enabled debugging types, use the display debugging command.
For information about the terminal monitor command, refer to Information Center
Command.

information.
Use the undo terminal debugging command to disable terminal display for debugging
information.
By default, terminal display for debugging information is disabled.
Note that:
zTo display the debugging information on the terminal, you need to configure both
the terminal debugging and terminal monitor commands.
zIf you execute the undo terminal monitor command, you will disable the
monitoring of the log, trap, and debugging information on the current terminal.
Thereby, no log, trap, or debugging information will be displayed on the terminal.
zThe configuration of the terminal debugging command takes effect for the
current connection only. If the terminal re-establishes a connection, the terminal

2.1.1 ping
Syntax

[ ip ] [ -n ] [ - p pattern ] [ -q ] [ -s packetsize ] [ -t timeout ] [ -tos tos ] [ -v ] host
View
Any view
Parameters
-a ip-address: Specifies the source IPaddress to send ICMPECHO-REQUESTpacket.
This IP address must be a local interface IP address.
-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: Specifies the socket to be in DEBUGGING mode. By default, the socket is in
non-DEBUGGING mode.
-f: Specifies to discard a packet directly instead of fragmenting it if its length is greater
than the maximum transmission unit (MTU) of the interface.
-h ttl: Specifies the Time To Live (TTL) value of the ICMP ECHO-REQUEST packets in
the range 1 to 255. By default, the TTL value is 255.
-i interface-type interface-number: Specifies the ICMP echo request sending interface
by its type and number. With the interface specified, the TTL of packets are set to 1
automatically to test the directly-connected device (the IPaddress of the device is in the
same network segment with that of the interface).
ip: Specifies the device to support IPv4. By default, the device supports IPv4.
-n: Specifies to directly 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 all
ffs. 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 without the details. By default, all the
information including the details and statistics will be displayed.
-s packetsize: Specifies the size (in bytes) of each ICMP ECHO-REQUEST packet
(excluding the IP and ICMP headers). The packetsize argument ranges from 20 to
32,000 and defaults to 56 bytes.
-t timeout: Specifies the timeout time (in milliseconds) before an ICMP ECHO-REPLY
packet is received after an ICMP ECHO-REQUEST packet is sent. The timeout
argument ranges from 0 to 65535 ms and defaults to 2,000 ms.
-tos tos: Specifies the ToS value of the ICMP ECHO-REQUEST packets in the range 0
to 255. By default, this value is 0.
-v: Specifies to display other ICMP packets received (that is, non-ECHO-REPLY
packets). By default, other ICMP packets like non-ECHO-REPLY packets are not
displayed.
host: Domain name or IP address of the destination host.
Note:
The ping command also supports the ipv6 keyword. For details, refer to IPv6
Management Command.
Description
Use the ping command to check the reachability of a host, and output the related
statistics information.
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:
zResponse status of the destination to each ICMP ECHO-REQUEST packet,
including the number of bytes, packet sequence number, TTL and response time
of the response packet if the response packet is received within the timeout time. If
no response packet is received within the timeout time, the message "Request
time out" is displayed instead.
zFinal 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 if the network transmission speed is slow.

string
View
Any view
Parameters
-a source-ip: Specifies the source interface IP address used by this command.
-f first-ttl: Specifies the initial TTL value of the packets to be sent, so as to only display
the addresses of 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
3, 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: Specifies 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 only displays the addresses of those gateways from
the source address to hop according to the hop count specified by the argument. For
example, if the max-ttl argument is 5, the command displays the addresses of the

Command Manual – System Maintenance and Debugging

2-4
gateways from the source to the fifth hop. The max-ttl argument ranges from 1 to 255
and defaults to 30.
-p port: Specifies 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: Specifies the number of packets to be sent each time. The num-packet
argument ranges from 0 to 65,535 and defaults to 3.
-w timeout: Specifies 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.
Note:
The tracert command also supports the ipv6 keyword. For details, refer to IPv6
Management Command.
Description
Use the tracert command to trace the gateways that the test packets pass through
from the source device to device the destination. This command is mainly used to
check the network connectivity and help locate the network faults.
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 TTLis 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 faulty by using the ping command, you can use the
tracert command to find where the fault is in the network.
The tracert command can output the IP addresses of all the gateways that the packets
pass through to the destination. It outputs the string "***" if the response from a gateway
times out.
Examples
# Trace the gateways that the packets pass through to the destination with IP address
