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.
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
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.

3
-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 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 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.
-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.
-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 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.

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. (The address selection rule is defined by RFC 3484.)

6
-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.
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 use the name of the destination host to perform the ipv6 ping operation, you must first configure DNS
on the device. Otherwise, the ipv6 ping operation fails.
To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.
Examples
# Test whether the IPv6 address (2001::2) is reachable.

tracert
Use tracert to trace the path the packets traverse from source to destination.
Syntax
tracert [ -a source-ip | -f first-ttl |-m max-ttl | -p port | -q packet-number | -t tos | { -topology topo-name
|-vpn-instance vpn-instance-name } | -w timeout ] * host

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.
-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.
-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.

•Domain name (or IP address, if the domain name is not configured) of the
first hop.
•The round-trip time of the three probe packets.
The number of packets that can be sent in each probe can be set through the
-q keyword.
MPLS Label=100048 Exp=0
TTL=1 S=1
ICMP timeout packets on an MPLS network, carrying MPLS label information:
•Label—Label value that is used to identify a forwarding equivalence class
(FEC).
•Exp—Reserved, usually used for class of service (CoS).
•TTL—TTL value.
•S—MPLS supports multiple levels of labels. Value 1 indicates that the label
is at the bottom of the label stack, and value 0 indicates that the label is in
another label stack.
