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

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.

-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.

network-admin

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.

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 (.).

tracert

Use tracert to trace the path that 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 | -vpn-instance vpn-instance-name [ -resolve-as { global | none |

vpn } ] | -w timeout ] * host

Views

Any view

Predefined user roles

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.

-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

7

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

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.

580 ms 470 ms 80 ms

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.

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.

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

10

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.

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 excessive 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 System Management Configuration Guide.

Examples

# Enable debugging for the device management module.

<Sysname> debugging dev

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 the voice operation.

<Sysname> system-view

[Sysname] nqa entry admin test

[Sysname-nqa-admin-test] type voice

[Sysname-nqa-admin-test-voice] advantage-factor 10

agent-type

Use agent-type to specify the SNMP agent type for the SNMP DCA operation.

Use undo agent-type to restore the default.

Syntax

agent-type { net-snmp | user-defined | windows }

undo agent-type

14

Default

The default SNMP agent type is Net-SNMP.

Views

Predefined user roles

network-admin

Parameters

net-snmp: Specifies the Net-SNMP agent type.

user-defined: Specifies the user-defined agent type.

windows: Specifies the Windows agent type.

Usage guidelines

The SNMP DCA operation monitors the performance of a device running an SNMP agent. It collects

the CPU, memory, and disk usage from the SNMP agent and determines the device performance

based on the collected object values and their associated thresholds and weights.

Different SNMP agent types use different OIDs for the CPU, memory, and disk usage objects. Make

sure the SNMP agent type specified in the SNMP DCA template matches the type of the SNMP

agent to be monitored.

For Net-SNMP or Windows SNMP agents, the NQA client has built-in OIDs to collect the CPU,

memory, and disk usage objects. You can use the cpu, memory, and disk commands to set the

thresholds and weights for these objects. You can also use the oid command to configure custom

SNMP objects.

For SNMP agents of the user-defined type, the NQA client does not have predefined SNMP objects

to collect. You must use the oid command to configure the interested SNMP objects and their

associated thresholds and weights.

Examples

# Set the SNMP agent type to Windows for SNMP DCA template test.

<Sysname> system-view

[Sysname] nqa template snmpdca test
