Ping and tracert commands
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

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.
-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.
2
-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.
-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.

tracert
Use tracert to trace the path that the packets traverse from source to destination.
Syntax
tracert [ -a source-ip | -f first-ttl | -i interface-type interface-number
| -m max-ttl | -p port | -q packet-number | -t tos | -vpn-instance
vpn-instance-name [ -resolve-as { global | none | vpn } ] | -w timeout ] * host

network-admin
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.
-i interface-type interface-number: Specifies the source interface of probe packets. If
you do not specify this option, the system looks up the routing table or forwarding table for a
matching route and uses the output interface of that route as the source interface of probe packets.
-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.
7
-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
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

Probe result of the probe packets that contain a TTL value of 2, including
the following information about the second hop:
• Domain name of the hop. If no domain name is configured, the IP
address is displayed as the domain name.
• IP address of the hop. The IP address is displayed in parentheses.
• Number of the AS that the hop belongs to. The AS number appears
only when it is found for the hop in the specified routing table.
• The round-trip time of the probe packets.
The number of packets that can be sent in each probe can be set by using
the
-q
keyword.
tracert ipv6
Use tracert ipv6 to display the path that the IPv6 packets traverse from source to destination.
Syntax

Parameters
-a source-ipv6: Specifies a valid IPv6 address on the device as the source IPv6 address of the
probe packets. If you do not specify a source IPv6 address, the source IPv6 address of the probe
packets is the IPv6 address of the outbound interface.
-f first-hop: Specifies the TTL value of the first packet. The value range is 1 to 255, and the
default is 1. The value must be no greater than the value of the max-hops argument.
-i interface-type interface-number: Specifies the source interface of probe packets. If
you do not specify this option, the system looks up the routing table or forwarding table for a
matching route and uses the output interface of that route as the source interface of probe packets.
You must specify this option if the destination address is a multicast address or a link-local address.
-m max-hops: Specifies the maximum number of hops allowed for a packet. The value range is 1
to 255, and the default is 30. The value must be no smaller than the value of the first-hop
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 sent each time. The value range is 1
to 65535, and the default is 3.
-t traffic-class: Specifies the traffic class value in an IPv6 probe packet. 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 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 of a probe packet. The
value range is 1 to 65535, and the default is 5000.
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
After identifying network failure with the ping ipv6 command, you can use the tracert ipv6
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
packets traverse, execute the tracert ipv6 command twice, once with the -resolve-as
global keywords and again with the -resolve-as vpn keywords.
10
The output from 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.
Before starting an IPv6 tracert operation, you must enable sending of ICMPv6 destination
unreachable messages on the intermediate devices between the source and destination. The IPv6
tracert operation stops if any one of the following ICMPv6 destination unreachable messages is
received:
•
!N—No route to destination.
•
!P—Communication with destination administratively prohibited by filtering policies.
•
!A—Address unreachable. The unreachable reason is unknown.
•
!S—Beyond scope of source address. This message is displayed if the probe packet has a
link-local source address and a non-link-local destination address. Such a packet cannot be
delivered to the destination without leaving the scope of the source address.
To abort the tracert operation during the execution of the command, press Ctrl+C.
