Ping, tracert, and system debugging
commands
debugging
Use debugging to enable debugging for a module.
Use undo debugging to disable debugging for a module.
Syntax
debugging { all [ timeout time ] | module-name [ option ] }
undo debugging { all | module-name [ option ] }
Default
Debugging functions are disabled for all modules.
Views
User view
Predefined user roles
network-admin
Parameters
all: Enables all debugging functions.
timeout time: Specifies the timeout time for the debugging all command. When all debugging is enabled,
the system automatically executes the undo debugging all command after the timeout time. The time
argument is in the range of 1 to 1440 minutes.
module-name: Specifies a module by its name, such as arp or device. To display the current module
name, use the debugging ? command.
option: Specifies the debugging option for a module. The option number and content differ for different
modules. To display the supported options, use the debugging module-name ? command.
Usage guidelines
Output of debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition.
Examples
# Enable debugging for the device management module.
<Sysname> debugging dev

ping
Use ping to determine whether the destination IP address is reachable, and display related statistics.
ip: Distinguishes between a destination host name and the ping command keywords if the name of the destination host is i, ip, ipv, ipv6, l, ls, or lsp. For example, you must use the command in the form of ping
ip ip instead of ping ip if the destination host name is ip.
-a source-ip: Specifies an IP address of the device as the source IP address of ICMP echo requests. If this
option is not specified, the source IP address of ICMP echo requests is the primary IP address of the
outbound interface.
-ccount: Specifies the number of ICMP echo requests that are sent to the destination. The value range is
1 to 4294967295, and the default is 5.
2
-f: Sets the "do-not-fragment" bit in the IP header.
-h ttl: Specifies the TTL value of ICMP echo requests. The value range is 1 to 255, and the default is 255.
-i interface-type interface-number: Specifies the source interface for ICMP echo requests. If you do not
specify this option, the system uses the primary IP address of the matching route's egress interface as the
source interface for ICMP echo requests.
-minterval: Specifies the interval (in milliseconds) to send ICMP echo requests. The value range is 1 to
65535, and the default is 200.
-n: Disables domain name resolution for the host argument. If the host argument represents the host name
of the destination, and if this keyword is not specified, the device translates host into an address.
-ppad: Specifies the value of the pad field in an ICMP echo request, in hexadecimal format, 1 to 8 bits.
The pad argument is in the range of 0 to ffffffff. If the specified value is less than 8 bits, 0s are added in
front of the value to extend it to 8 bits. For example, if pad is configured as 0x2f, then the packets are
padded with 0x0000002f to make the total length of the packet meet the requirements of the device. By
default, the padded value starts from 0x01 up to 0xff, where another round starts again if necessary,
such as 0x010203…feff01….
-q: Displays only the summary statistics. If this keyword is not specified, the system displays all the ping
statistics.
-r: Records the addresses of the hops (up to 9) the ICMP echo requests passed. If this keyword is not
specified, the addresses of the hops that the ICMP echo requests passed are not recorded.
-s packet-size: Specifies the length (in bytes) of ICMP echo requests (excluding the IP packet header and
the ICMP packet header). The value range is 20 to 8100, and the default is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. The value range is 0 to
65535, and the default is 2000. If the source does not receive an ICMP echo reply within the timeout,
it considers the ICMP echo reply timed out.
-tostos: Specifies the ToS value of ICMP echo requests. The value range is 0 to 255, and the default is
0.
-v: Displays non-ICMP echo reply packets. If this keyword is not specified, the system does not display
non-ICMP echo reply packets.
-topologytopo-name: Specifies the topology to which the destination belongs, where topo-name is a
case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this
option.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination
is on the public network, do not specify this option.
host: Specifies the IP address or host name of the destination. The host name is a case-insensitive string
of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore
(_), and dot (.).
Usage guidelines
Examples
To use the name of the destination host to perform the ping operation, you must first configure the DNS
on the device. Otherwise, the ping operation will fail.
To abort the ping operation during the execution of the command, press Ctrl+C.

tracert
Use tracert to trace the path the packets traverse from source to destination.
-a source-ip: Specifies an IP address of the device as the source IP address of probe packets. If this option
is not specified, the source IP address of probe packets is the primary IP address of the outbound
interface.
-f first-ttl: Specifies the TTL of the first packet sent to the destination. The value range is 1 to 255, and the
default is 1. It must be no greater than the value of the max-ttl argument.
-m max-ttl: Specifies the maximum number of hops allowed for a probe packet. The value range is 1 to
255, and the default is 30. It must be no smaller than the value of the first-ttl argument.
-p port: Specifies an invalid UDP port of the destination. The value range is 1 to 65535, and the default
is 33434.
-qpacket-number: Specifies the number of probe packets to send per hop. The value range is 1 to 65535,
and the default is 3.
-t tos: Specifies the ToS value of probe packets. The value range is 0 to 255, and the default is 0.
-topology topo-name: Specifies the topology to which the destination belongs, where topo-name is a
case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this
option.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination
is on the public network, do not specify this option.
-w timeout: Specifies the timeout time in milliseconds of the reply packet for a probe packet. The value
range is 1 to 65535, and the default is 5000.
host: Specifies the IP address or host name of the destination. The host name is a case-insensitive string
of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore
(_), and dot (.).
Usage guidelines
After identifying network failure with the ping command, use the tracert command to locate failed nodes.
The output of the tracert command includes IP addresses of all the Layer 3 devices that the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message. The reason might be the destination is unreachable or sending ICMP
timeout/destination unreachable packets is disabled.
To abort the tracert operation during the execution of the command, press Ctrl+C.

After identifying network failure with the ping ipv6 command, you can use the tracert ipv6 command to
locate failed nodes.
The output of the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices that the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message. The reason might be the destination is unreachable or sending ICMP
timeout/destination unreachable packets is disabled.
To abort the tracert operation during the execution of the command, press Ctrl+C.
Examples
# Display the path that the packets traverse from source to destination (2001:3::2).
<Sysname> tracert ipv6 2001:3::2

Parameters
factor: Specifies the advantage factor in the range of 0 to 20.
Usage guidelines
The evaluation of voice quality depends on users' tolerance for voice quality. For users with higher
tolerance for voice quality, use the advantage-factor command to set an advantage factor. When the
system calculates the ICPIF value, it subtracts the advantage factor to modify ICPIF and MOS values for
voice quality evaluation.
Examples
# Set the advantage factor to 10 for voice operations.

Parameters
cipher: Sets a ciphertext community name.
simple: Sets a plaintext community name.
community-name: Specifies the community name. This argument is case sensitive. If you specify the
simple keyword, the name must be a string of 1 to 32 characters. If you specify the cipher keyword, the
name must be a string of 33 to 73 characters.
13
Usage guidelines
Execute this command to specify the community name on the NQA client if the SNMP agent runs
SNMPv1 or SNMPv2c. The specified community name must be the read-only community name that has
been configured on the SNMP agent.
If the SNMP agent runs SNMPv3, you do not need to specify the community name on the NQA client.
For security purposes, the community name configured in plain text or cipher text is saved in cipher text.
Examples
# Specify readaccess as the community name for SNMPv1 and SNMPv2c probe packets.

Predefined user roles
network-admin
Parameters
string: Specifies a case-sensitive string of 1 to 200 characters.
Usage guidelines
If the payload length is smaller than the string length, only the first part of the string is filled. For example,
if you configure the string as abcd and set the payload size to 3 bytes, abc is filled.
If the payload length is greater than the string length, the system fills the payload with the string cyclically
until the payload is full. For example, if you configure the string as abcd and the payload size as 6 bytes,
abcdab is filled.
How the string is filled depends on the operation type.
• For the ICMP echo operation, the string fills the whole payload of an ICMP echo request.
• For the UDP echo operation, the first five bytes of the payload of a UDP packet are for special
purpose. The string fills the remaining part of payload.
14
p
• For the UDP jitter operation, the first 68 bytes of the payload of a UDP packet are for special
purpose. The string fills the remaining part of the payload.
• For the voice operation, the first 16 bytes of the payload of a UDP packet are for special purpose.
The string fills the remaining part of the payload.
• For the path jitter operation, the first four bytes of the payload of an ICMP echo request are for
special purpose. The string fills the remaining part of payload.
Examples
# Specify abcd as the payload fill string for ICMP echo requests.

display nqa statistics
Use display nqa statistics to display NQA operation statistics.
admin-name operation-tag: Specifies an NQA operation by its administrator name and operation tag.
The admin-name argument represents the name of the administrator who creates the NQA operation.
The operation-tag argument represents the operation tag. Each of the arguments is a case-insensitive
string of 1 to 32 characters that cannot contain hyphens (-). If you do not specify an NQA operation, the
command displays statistics for all NQA operations.
28
Usage guidelines
The statistics are generated after the NQA operation completes. If you execute the display nqa statistics
command before the operation completes, the statistics are displayed as all 0s.
If a reaction entry is configured, the command displays the monitoring results of the reaction entry in the
period specified by the statistics internal command. The result fields display hyphens (-) in one of the
following conditions:
• The threshold type is average value.
• The monitored performance metric is ICPIF or MOS for the voice operation.
The command is not available for the UDP tracert operation.

Parameters
get: Gets a file from the FTP server.
put: Transfers a file to the FTP server.
Usage guidelines
When you perform the put operation with the filename command configured, make sure the file exis ts on
the NQA client.
If you get a file from the FTP server, make sure the file specified in the URL exists on the FTP server. The
NQA client does not save the file obtained from the FTP server.
Use a small file for the FTP operation. A big file might result in transfer failure because of timeout, or might
affect other services for occupying much network bandwidth.

Parameters
times: Specifies the probe times.
• For the UDP tracert operation, this argument specifies the times of probes to each hop along the
path. The value range for this argument is 1 to 10.
• For other types of operations, this argument specifies the times of probes to the destination per
operation. The value range for this argument is 1 to 15.
49
Usage guidelines
The following describes how NQA performs different types of operations:
• A TCP or DLSw operation sets up a connection.
• A UDP jitter or voice operation sends a number of probe packets. The number of probe packets is
set by using the probe packet-number command.
• An FTP operation uploads or downloads a file.
• An HTTP operation gets a Web page.
• A DHCP operation gets an IP address through DHCP.
• A DNS operation translates a domain name to an IP address.
• An ICMP echo sends an ICMP echo request.
• A UDP echo operation sends a UDP packet.
• An SNMP operation sends one SNMPv1 packet, one SNMPv2c packet, and one SNMPv3 packet.
• A path jitter operation is accomplished in the following steps:
a. The operation uses tracert to obtain the path from the NQA client to the destination. A
b. The NQA client sends ICMP echo requests to each hop along the path. The number of ICMP
maximum of 64 hops can be detected.
echo requests is set by using the probe packet-number command.
• A UDP tracert operation determines the routing path from the source to the destination. The number
of probes to each hop is set by using the probe count command.
If an operation is to perform multiple probes, the NQA client starts a new probe in one of the following
conditions:
• The NQA client receives responses to packets sent in the last probe.
• The probe timeout time expires.
This command is not available for the voice and path jitter operations. Each of these operations performs
only one probe.

path-change: Sends a trap when the UDP tracert operation detects a different path to the destination.
probe-failure consecutive-probe-failures: Sends a trap to the NMS if the number of consecutive probe
failures in an operation is greater than or equal to consecutive-probe-failures. The value range for the
consecutive-probe-failures argument is 1 to 15. The system counts the number of consecutive probe
failures for each operation, so multiple traps might be sent.
test-complete: Sends a trap to indicate that the operation is completed.
test-failure: Sends a trap when an operation fails. For operations other than UDP tracert operation, the
system counts the total number of probe failures in an operation. If the number reaches or exceeds the
value for the cumulate-probe-failures argument, a trap is sent for the operation failure.
cumulate-probe-failures: Specifies the total number of probe failures in an operation. The value range for
the cumulate-probe-failures argument is 1 to 15. This argument is not supported by the UDP tracert
operation.
Usage guidelines
The UDP jitter and voice operations support only the test-complete keyword.
