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 module-name [ option ]
undo debugging 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.
Usage guidelines
Output from debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition.
The system sends the debugging command output as debug messages to the device information
center. The information center then sends the messages to appropriate destinations based on the
log output configuration. For more information about configuring debug message output, see
Network Management and Monitoring Configuration Guide.
Examples
# Enable debugging for the device management module.
<Sysname> debugging dev

display debugging
Use display debugging to display the enabled debugging features for a module or for all modules.
Syntax
display debugging [module-name ]

network-operator
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 | { -topology topo-name | -vpn-instance
vpn-instance-name } ] * host
Views

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, or ipv6. 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.

3
-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 ICMPecho requests is the primary IPaddress
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 "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.
-m interval: Specifies the interval (in milliseconds) to send ICMPecho 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 thepacket 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 ICMPecho 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.
-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.

4
-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
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.
-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 8100, 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 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.
