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

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:
z 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.
z 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.

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.
