Ping, tracert, and system debugging
commands
debugging
Use debugging to enable debugging for a module.
Use undo debugging to disable debugging for a module or for all modules.
Syntax
debugging module-name [ option ]
undo debugging { all | module-name [ option ] }
Default
Debugging is disabled for all modules.
Views
User view
Predefined user roles
network-admin
Parameters
module-name: Specifies a module by its name, such as arp or device. For a list of supported
modules, use the debugging ? command.
option: Specifies the debugging option for a module. Available options vary by module. To display
the debugging options supported by a module, use the debugging module-name ? command.
all: Specifies all modules.
Usage guidelines
CAUTION:
Output of e
xcessive debugging messages increases the CPU usage and downgrades the system
performance.
To guarantee system performance, enable debugging only for modules that are in an
exceptional condition.
The system sends generated debug messages to the device information center, which then sends
the messages to appropriate destinations based on the log output configuration. For more
information about the information center, see Network Management and Monitoring Configuration
Guide.
To disable all types of debugging by using a shortcut method, press Ctrl+O. To display the shortcut
keys supported by the device, use the display hotkey command. If you log in to the device
through terminal software and shortcut key Ctrl+O has been used by the software, the shortcut key
cannot disable all types of debugging on the device.
Examples
# Enable debugging for the device management module.
<Sysname> debugging dev

Parameters
module-name: Specifies a module by its name. For a list of supported modules, use the display
debugging ? command. If you do not specify a module name, this command displays the enabled
debugging features for all modules.
Examples
# Display all enabled debugging features.

ping
Use ping to test the reachability of the destination IP address and display ping statistics.
Syntax
ping [ ip ] [ -a source-ip | -c count | -f | -h ttl | -i interface-type
interface-number | -m interval | -n | -p pad | -q | -r | -s packet-size | -t
timeout | -tos tos | -v | -vpn-instance vpn-instance-name ] * host
Views
Any view
Predefined user roles
network-admin
Parameters
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.
-c count: 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.
-f: Sets the "Don’t Fragment" bit in the IP header.
3
-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.
-m interval: 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.
-p pad: 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 9600, 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.
-tos tos: 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.
-vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the
destination belongs. The vpn-instance-name argument represents the VPN instance name, 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
To ping a device identified by its host name, configure the DNS settings on the device first. If the DNS
settings are not configured, the ping operation fails.
To abort the ping operation during the execution of the command, press Ctrl+C.

Parameters
-a source-ipv6: Specifies an IPv6 address of the device as the source IP address of ICMP echo
requests. If this option is not specified, the source IPv6 address of ICMP echo requests is the IPv6
address of the outbound interface. See RFC 3484 for information about the address selection rule.
-c count: Specifies the number of ICMPv6 echo requests that are sent to the destination. The
value range is 1 to 4294967295, and the default is 5.
6
-i interface-type interface-number: Specifies the source interface for ICMPv6 echo
requests. This option must be specified when the destination address is a multicast address or a link
local address. 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 ICMPv6 echo requests.
-m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply. The value
range is 1 to 65535, and the default is 1000.
-q: Displays only the summary statistics. If you do not specify this keyword, the system displays all
the ping statistics.
-s packet-size: Specifies the length (in bytes) of ICMPv6 echo requests (excluding the IPv6
packet header and the ICMPv6 packet header). The value range is 20 to 9600, and the default is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The value range
is 0 to 65535, and the default is 2000.
-tc traffic-class: Specifies the traffic class value in an ICMPv6 packet. The value range is 0
to 255 and the default is 0.
-v: Displays detailed information (including the dst field and the idx field) about ICMPv6 echo
replies. If this keyword is not specified, the system only displays brief information (not including the
dst field and the idx field) about ICMPv6 echo replies.
-vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the
destination belongs. The vpn-instance-name argument represents the VPN instance name, 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 IPv6 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
To ping a device identified by its host name, configure the DNS settings on the device first. If the DNS
settings are not configured, the IPv6 ping operation fails.
To abort the IPv6 ping operation during the execution of the command, press Ctrl+C.

tracert
Use tracert to trace the path that the packets traverse from source to destination.
Syntax
tracert [ -a source-ip | –e | -f first-ttl | -m max-ttl | -p port | -q

Parameters
-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.
-e: Enables the device to use a fixed destination port number in probe packets. If you do not specify
this keyword, the device increases the destination port number by 1 each time it sends probe
packets to the destination in a tracert operation. Some firewall devices might falsely identify tracert
probe packets with incremental destination port numbers as port scanning attack packets. If such a
device exists, specify the -e keyword to ensure that the tracert operation can be performed correctly.
-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.
-q packet-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.
-vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the
destination belongs. The vpn-instance-name argument represents the VPN instance name, a
case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify
this option.
-resolve-as: Specifies a routing table for autonomous system (AS) resolution. Tracert searches
the specified routing table for the AS that each hop along the path belongs to. If you do not specify
this keyword, the global routing table is used. If the AS information is found, this command displays
the AS number next to the address of the hop in the probe result.
•
global: Specifies the global routing table.
•
none: Disables AS resolution.
•
vpn: Specifies the VPN routing table.
-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.
If the destination address is on the public network, you do not need to specify the -resolve-as
keyword to obtain the AS information. The device automatically uses the global routing table for AS
resolution.
If the destination address is on a private network, address information of intermediate hops might be
stored in either the global routing table or the VPN routing table. To learn the AS path that the
9
packets traverse, execute the tracert command twice, once with the -resolve-as global
keywords and again with the -resolve-as vpn keywords.
The output from 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.
Before starting a tracert operation, you must enable sending of ICMP destination unreachable
messages on the intermediate devices between the source and destination. The tracert operation
stops if any one of the following ICMP destination unreachable messages is received:
•
!N—Network unreachable.
•
!H—Destination host unreachable.
•
!P—Protocol unreachable. The protocol number is unknown.
•
!F—Fragmentation needed. This message indicates that packet fragmentation is needed but
the "Don’t Fragment" bit is set on an immediate device.
•
!W—Destination host unknown.
•
!Q—Network unreachable for ToS.
•
!T—Host unreachable for ToS.
•
!X—Communication administratively prohibited by filtering policies.
•
!V—Host precedence violation.
•
!C—Precedence cutoff in effect.
To abort the tracert operation during the execution of the command, press Ctrl+C.
