Parameters

analyzer-id: Specifies an analyzer ID in dotted decimal format. It must be the same as the analyzer ID configured on the analyzer.

udp-port port-number: Specifies a UDP port on the analyzer for the collector to communicate with the analyzer. The value range is 1024 to 65535, and the default is 53312. As a best practice, use the default value. If you use other values, make sure the specified value is the same as that configured on the analyzer by using the protocol udp-port command.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. To specify an analyzer on the public network, do not specify this option.

Usage guidelines

A collector instance must be bound to an analyzer so that the collector can send instance-specific data to the analyzer.

The binding between the analyzer and the collector is used as follows:

1.     The collector encapsulates the data collected from MPs into packets, uses the analyzer ID bound to a collector instance as the destination IPv4 address, and sends the packets to the analyzer.

2.     The analyzer compares the analyzer ID in the packets with its own ID.

¡     If a match is found, the analyzer accepts the packets and summarizes the data in the packets.

¡     If no match is found, the analyzer identifies the packets illegal and discards them.

For the successful communication, make sure the specified analyzer ID meets the following requirements:

·     The analyzer ID and a collector can reach each other.

·     The analyzer ID bound to a collector instance must be the same as the analyzer ID configured on an analyzer by using the analyzer id command.

You can bind an analyzer to a collector instance or a specific collector.

·     An analyzer specified in collector view is bound to all collector instances.

·     An analyzer specified in collector instance view is bound to the specific collector instance.

The analyzer ID in collector instance view takes precedence over that in collector view. If no analyzer ID is specified in collector instance view, the analyzer ID in collector view applies.

A collector and a collector instance can be bound to only one analyzer. If you execute this command multiple times in the same view, the most recent configuration takes effect.

Examples

# Bind all collector instances to the analyzer with ID 10.1.1.1.

<Sysname> system-view

[Sysname] inqa collector

[Sysname-inqa-collector] analyzer 10.1.1.1

# Bind collector instance 1 to the analyzer with ID 11.1.1.1.

Predefined user roles

network-admin

Parameters

collector-id: Specifies a collector ID in dotted decimal format, for example, 10.1.1.1. The collector ID must be an IPv4 address that already exists on the collector.

Usage guidelines

The collector ID is used for communication between the analyzer and collector as follows:

1.     The collector encapsulates the data collected from MPs into packets, uses its ID as the source IPv4 address, and sends the packets to the analyzer.

2.     The analyzer compares the collector ID in the packets with collector IDs bound to analyzer instances.

¡     If a match is found, the analyzer accepts the packets and summarizes the data in the packets.

¡     If no match is found, the analyzer identifies the packet illegal and discards them.

For the successful communication, make sure the specified collector ID meets the following requirements:

·     The ID must be globally unique. As a best practice, configure the Router ID of the device as the collector ID.

·     The specified collector ID must be the same as the collector ID bound to an analyzer instance on the analyzer.

You can execute the collector command on the analyzer to bind the specified collector ID to an analyzer instance.

·     The collector ID and the analyzer can reach each other.

Predefined user roles

network-admin

Parameters

tos-bit tos-bit: Specifies a ToS field bit. The device supports only value 5.

Usage guidelines

iNQA uses ToS field bit 5 in the IPv4 packet header as the flag bit. By setting the flag bit value to 1 or 0 alternately at intervals to distinguish a target flow from unintended traffic flows.

The ToS field consist of a 6-bit (bits 0 to 5) DSCP filed and a 2-bit (bits 6 and 7) ECN field. If bit 5 is used as the flag bit, to avoid inaccurate packet loss statistics, do not use it for DSCP purposes.

To modify the flag bit for a collector instance that is already enabled, you must disable the collector instance first.

Examples

# Specify ToS field bit 5 as the flag bit.

<Sysname> system-view

[Sysname] inqa collector

[Sysname-inqa-collector] flag loss-measure tos-bit 5

flow (collector instance view)

Use flow to specify a flow to be monitored by a collector instance.

Use undo flow to remove the flow settings.

Syntax

flow { backward | bidirection | forward } { destination-ip dest-ip-address [ dest-mask-length ] | dscp dscp-value | protocol { { tcp | udp } { destination-port dest-port-number1 [ to dest-port-number2 ] | source-port src-port-number1 [ to src-port-number2 ] } * | protocol-number } | source-ip src-ip-address [ src-mask-length ] } *

undo flow { backward | bidirection | forward }

Default

No flow is specified for a collector instance.

Predefined user roles

network-admin

Parameters

backward: Specifies a backward flow.

bidirection: Specifies the symmetric bidirectional flows. If you specify this keyword, both the src-ip-address and dest-ip-address arguments are required.

forward: Specifies a forward flow.

destination-ip dest-ip-address: Specifies a destination IPv4 address of the flow, in dotted decimal format. Only the unicast IPv4 addresses are supported.

dest-mask-length: Specifies a mask length for the destination IPv4 address. The value range is 1 to 32, and the default is 32.

dscp dscp-value: Specifies a DSCP value of the flow, in the range of 0 to 63. If bit 5 is used as the flag bit, do not specify this option to avoid inaccurate packet loss statistics.

protocol: Specifies a protocol type of the flow.

·     { tcp | udp }: Specifies the TCP or UDP protocol.

¡     destination-port dest-port-number1 [ to dest-port-number2 ]: Specifies a single destination port or a range of destination ports. The value range is 0 to 65535. For a port range, the dest-port-number2 argument must be higher than the dest-port-number1 argument.

¡     source-port src-port-number1 [ to src-port-number2 ]: Specifies a single source port or a range of source ports. The value range is 0 to 65535. For a port range, the src-port-number2 argument must be higher than the src-port-number1 argument.

·     protocol-number: Specifies the number of the protocol type. The value range is 0 to 255, excluding 6 (TCP protocol number) and 17 (UDP protocol number).

source-ip src-ip-address: Specifies a source IPv4 address of the flow, in dotted decimal format. Only the unicast IPv4 addresses are supported.

src-mask-length: Specifies a mask length for the source IPv4 address. The value range is 1 to 32, and the default is 32.

Usage guidelines

The target flows are key elements for iNQA operations. You can specify a flow by using any combination of the following items: protocol type, source IPv4 address, destination IPv4 address, source port number, destination port number, and DSCP value. Using more items defines a more explicit flow and generates more accurate analysis data.

A collector instance can monitor a maximum of two flows. Follow these guidelines when you specify the target flows:

·     To monitor only one flow, specify the forward keyword. The collector instance does not support monitoring only a backward flow.

·     To monitor two flows:

¡     If the endpoint devices of the two flows are the same, use the bidirection keyword, and specify both the destination IPv4 address and source IPv4 address..

¡     If the endpoint devices of the two flows are not identical, specify a forward flow and then a backward flow. Alternatively, you can create two collector instances, and specify a forward flow in each collector instance.

For the flows to be monitored by different collector instances, the flow attributes must not be identical.

For a forward flow and backward flow monitored by a collector instance, the flow attributes cannot be all identical. If they have the same attributes except the direction, define them as bidirectional flows.

Examples

# Configure collector instance 1 to monitor the forward UDP flow from 10.1.1.1 to 20.1.1.1 with the source port number 1025.

Usage guidelines

The intelligent network quality analyzer (iNQA) operations include the following device roles:

·     Collector—Manages measurement points (MPs), collects data from MPs, and reports the data to the analyzer.

·     Analyzer—Collects the data from collectors and summarizes the data.

After you configure this command on a device, the device functions as a collector.

You can enable the collector and analyzer functionalities on different devices or the same device.

Parameters

instance-id: Specifies a collector instance ID in the range of 1 to 8355838.

Usage guidelines

A collector collects data based on the collector instance. You can configure the target flows, MPs, measurement interval, and bound analyzer ID for a collector instance.

To collect packet loss statistics on the same target flow passing through multiple collectors, create an instance on the analyzer and each collector, and make sure the instance IDs are the same.

Examples

# Create instance 1 on the collector.

Parameters

interval: Specifies a measurement interval in seconds. The available values are 10, 60, and 600.

Usage guidelines

During a measurement interval, a collector instance counts the packets reported form MPs and reports the data results to the analyzer. Set a proper interval according to your measurement requirements and the actual network conditions.

The shorter the interval, the more frequently the data is reported to the analyzer, which might affect the processing performance of collector and the analyzer. Make sure the same collector instance on all collectors uses the same measurement interval.

Examples

# Set the measurement interval to 60 seconds for collector instance 1.

<Sysname> system-view

[Sysname] inqa collector

[Sysname-inqa-collector] instance 1

Predefined user roles

network-admin

Parameters

mid-point: Enable this feature on middle points. The middle points apply to point-to-point performance measurements.

duration: Specifies the number of minutes for which the measurement lasts. The values can be 5, 10, 15, and 30, and the default is 10.

Usage guidelines

iNQA counts the packet loss information in the specified time period. It is helpful when you want to measure the network performance in a time period or to accurately locate the fault points for packet loss.

This command will not be saved to the configuration file. The packet loss measurement cannot survive the master/subordinate, active/standby switchover, or device reboot.

For a collector instance, the fixed duration and continual packet loss measurements cannot be both enabled.

Examples

# Run the packet loss measurement for 30 minutes for collector instance 1.

Default

No MP is configured.

Views

Collector instance view

Predefined user roles

network-admin

Parameters

mp-id: Specifies an MP ID in the range of 1 to 16777215.

in-point: Specifies the MP as an ingress point. An ingress point colors the forward flow, and decolors the backward flow, and collects packet statistics for the forward flow.

mid-point: Specifies the MP as a middle point. A middle point only collects packet statistics for the target flow.

out-point: Specifies the MP as an egress point. An egress point decolors the forward flow, colors the backward flow, and collects packet statistics for the backward flow.

inbound: Specifies the flows entering the MP.

outbound: Specifies the flow leaving MP.

Usage guidelines

A collector instance measures the data passing through MPs. After specifying a collector instance, configure an MP.

Specify the in-point, mid-point, or out-point keyword as follows:

·     If the MP is the first point that the target flow passes through, specify the in-point keyword for the MP.

·     If the MP is the final point that the target flow passes through, specify the out-point keyword for the MP.

·     If you define an MP between an ingress point and egress point, specify the mid-point keyword for the MP. When packet loss occurs between an ingress point and egress point, you can specify middle points to locate the problem.

Specify the port direction as follows:

·     To collect the statistics on the flows entering the MP, specify the inbound keyword.

·     To collect the statistics on the flows leaving the MP, specify the outbound keyword.

One MP cannot be both an ingress point and an egress point of a measured flow.

Examples

# Configure ingress MP 100 for collector instance 1 to collect traffic data for the flows entering the MP.

Predefined user roles

network-admin

Parameters

analyzer-id: Specifies an analyzer ID in dotted decimal format, for example, 10.1.1.1. The analyzer ID must be an IPv4 address that already exists on the analyzer.

Usage guidelines

The analyzer ID is used for communication between the analyzer and collector as follows:

1.     The collector encapsulates the data collected from MPs into packets, uses the analyzer ID as the destination IPv4 address, and sends the packets to the analyzer.

2.     The analyzer compares the analyzer ID in the packets with its own ID.

¡     If a match is found, the analyzer accepts the packets and summarizes the data in the packets.

¡     If no match is found, the analyzer identifies the packets illegal and discards them.

For the successful iNQA communication, make sure the specified analyzer ID meets the following requirements:

·     The analyzer ID must be an IPv4 address that can be routable from the collector.

·     The specified analyzer ID must be the same as the analyzer ID bound to a collector instance on the collector.

·     As a best practice, configure the Router ID of the device as the analyzer ID.

With this command configured, iNQA uses the configured analyzer ID and the port number configured by the protocol udp-port command to start the UDP server. If the configured UDP port number is used by other services, the UDP server cannot be started, causing the configuration failure of this command.

Parameters

collector-id: Specifies a collector ID in dotted decimal format, for example, 10.1.1.1. The collector ID must be the same as that configured on the collector. If you do not specify this argument in the undo collector command, you unbind all collectors from the analyzer instance.

Usage guidelines

To bind multiple collectors to an analyzer instance, repeat this command. The analyzer instance collects and analyzes the reported data of all bound collectors.

Specify the collector ID the same as that specified on the collector in the collector id command.

After you enable the measurement functionality for an analyzer instance, you cannot modify the bound collectors. To modify the collectors bound to an analyzer instance, first disable the measurement functionality for the analyzer instance.

Table 6 Command output

Field

Description

Latest packet loss statistics for forward flow

Most recent statistics about target forward flow

Latest packet loss statistics for backward flow

Most recent statistics about target backward flow.

Period

Index of the measurement interval.

LostPkts

Number of lost packets.

PktLoss%

Packet loss rate.

Packet loss rate = (Total number of packets at the ingress MP – Total number of packets at the egress MP)/Total number of packets at the ingress MP.

If the clock of the collectors are not synchronized, or the ingress MP do not report any data, the packet loss rate might be negative. The minimum packet loss rate is –100%.

LostBytes

Number of lost bytes.

ByteLoss%

Byte loss rate.

Byte loss rate = (Total number of bytes at the ingress MP – Total number of bytes at the egress MP)/Total number of bytes at the ingress MP.

If the clock of the collectors are not synchronized, or the ingress MP do not report any data, the byte loss rate might be negative. The minimum packet loss rate is –100%.

flow (analyzer AMS view)

Use flow to specify the flow direction to be measured in an analyzer AMS.

Use undo flow to restore the default.

Syntax

flow { backward | bidirection | forward }

undo flow

Default

No flow direction is specified to be measured in the analyzer AMS.

Views

Predefined user roles

network-admin

Parameters

backward: Specifies a backward flow.

bidirection: Specifies the symmetric bidirectional flows.

forward: Specifies a forward flow.

Usage guidelines

The command is a must if you configure an AMS for point-to-point packet loss measurements.

The collector and analyzer each provide a flow command, and the direction keywords (forward, backward, and bidirection) in these commands function differently.

·     In collector instance view, the collector instance collects the statistics about the flows of the specified direction and reports the statistics to the analyzer.

·     In analyzer AMS view, the analyzer calculates the statistics about the flows of the specified direction.

The following matrix shows how the direction setting in the flow command results in different data calculation on the analyzer:

 

In collector instance view

In analyzer AMS view

Analyzer calculates data for

bidirection

forward

Only the forward flow.

The analysis data does not contains statistics for the backward flow.

forward

backward

Only for the backward flow.

Because the collectors does not report any backward flow data, the backward flow statistics in the AMS is 0.

 

Examples

# Specify forward flow to be measured in analyzer AMS 1 on analyzer 1.

<Sysname> system-view

[Sysname] inqa  analyzer

[Sysname-inqa-analyzer] instance 1

[Sysname-inqa-analyzer-instance-1] ams 1

network-admin

Parameters

collector collector-id: Specifies the ID of the collector where the MP resides, in dotted decimal format.

mp mp-id: Specifies an MP ID in the range of 1 to 16777215.

Usage guidelines

If packet loss occurs in a specific segment of the network, divide the network segment into multiple AMSs to locate the AMS where packet loss occurs.

The ingress MP group is required for an AMS. You can repeat this command to add multiple MPs to the ingress MP group.

Examples

# Add MP 100 of the collector with ID 10.1.1.1 to the ingress MP group for AMS 1 in analyzer instance 1.

Usage guidelines

The intelligent network quality analyzer (iNQA) operations include the following device roles:

·     Collector—Manages measurement points (MPs), collects data from MPs, and reports the data to the analyzer.

·     Analyzer—Collects the data from collectors and summarizes the data.

After you configure this command on a device, the device functions as an analyzer.

You can enable the collector and analyzer functionalities on different devices or the same device.

Examples

# Enable the analyzer functionality and enter its view.

<Sysname> system-view

[Sysname] inqa analyzer

[Sysname-inqa-analyzer]

instance (analyzer view)

Use instance to create an analyzer instance and enter its view, or enter the view of an existing analyzer instance.

Use undo instance to delete an analyzer instance.

Syntax

instance instance-id

undo instance instance-id

Default

No analyzer instance exists on an analyzer.

Views

Analyzer view

Predefined user roles

network-admin

Parameters

instance-id: Specifies an analyzer instance ID in the range of 1 to 8355838.

Usage guidelines

An analyzer instance collects and counts the measurement results for the same target flow passing through all collectors in the instance.

For an analyzer instance, you must bind it to a collector and choose to configure the description, packet loss upper limit, and packet loss lower limit. If you want to perform point-to-point performance measurements for an analyzer instance, configure AMSs.

To collect packet loss statistics on the same target flow passing through multiple collectors, create an instance on the analyzer and each collector, and make sure the instance IDs are the same.

Examples

# Create instance 1 on the analyzer.

<Sysname> system-view

[Sysname] inqa analyzer

[Sysname-inqa-analyzer] instance 1

loss-measure alarm

Use loss-measure alarm to configure packet loss logging for an analyzer instance.

Use undo loss-measure alarm to restore the default.

Syntax

loss-measure alarm upper-limit upper-limit lower-limit lower-limit

undo loss-measure alarm

Default

The packet loss logging is not configured for an analyzer instance. The analyzer will not generate logs for threshold crossing events.

Views

Analyzer instance view

Predefined user roles

network-admin

Parameters

upper-limit upper-limit: Specifies the packet loss upper limit, a string of 1 to 10 characters. The value range is 0.000001% to 100%, correct to six decimal places. The threshold is crossed if the packet loss rate exceeds it.

lower-limit lower-limit: Specifies the packet loss lower limit, a string of 1 to 10 characters. The value range is 0.000001% to 100%, correct to six decimal places. It must not be greater than the upper limit. The threshold is crossed if the packet loss rate drops below it.

Usage guidelines

iNQA calculates the packet loss rate periodically, and the analyzer generates a log on five consecutive crossings of a threshold.

·     If the packet loss rate exceeds the upper limit for consecutive five measurement intervals, the analyzer sends a log to the information center.

·     If the packet loss rate is less than the lower limit for consecutive five measurement intervals, the analyzer sends an event clearing log to the information center.

You can configure the information center to determine whether to output logs and the output destination. For more information about the information center, see "Configuring information center."

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the upper limit to 8% and the lower limit to 4.5% for analyzer instance 1.

<Sysname> system-view

[Sysname] inqa analyzer

[Sysname-inqa-analyzer] instance 1

[Sysname-inqa-analyzer-instance-1] loss-measure alarm upper-limit 8 lower-limit 4.5

measure enable (analyzer instance view)

Predefined user roles

network-admin

Usage guidelines

To avoid incorrect statistics on the analyzer, do not modify the iNQA settings on the collector when the measurement functionality of an analyzer instance is enabled. To modify the iNQA settings on a collector, perform the following steps:

1.     On the analyzer, execute the undo measure enable command to disable the measurement functionality of the analyzer instance bound to a collector.

2.     Log in to the collector and modify the collector settings.

3.     On the analyzer, execute the measure enable command to enable the measurement functionality of the analyzer instance.

Examples

# Enable the measurement functionality of analyzer instance 1.

<Sysname> system-view

[Sysname] inqa analyzer

[Sysname-inqa-analyzer] instance 1

[Sysname-inqa-analyzer-instance-1] measure enable

out-group

Use out-group to add an MP to the egress MP group for an AMS.

Use undo out-group to remove an MP from the egress MP group for an AMS.

Syntax

out-group collector collector-id mp mp-id

undo out-group [ collector collector-id mp mp-id ]

Default

The egress MP group does not have any MP.

Predefined user roles

network-admin

Parameters

collector collector-id: Specifies the ID of the collector where the MP resides, in dotted decimal format.

mp mp-id: Specifies an MP ID in the range of 1 to 16777215.

Usage guidelines

If packet loss occurs in a specific segment of the network, divide the network segment into multiple AMSs to locate the AMS where packet loss occurs.

The egress MP group is required for an AMS. You can repeat this command to add multiple MPs to an egress MP group.

Examples

# Add MP 200 of the collector with ID 2.1.1.1 to the egress MP group for AMS 1 in analyzer instance 1.

<Sysname> system-view

[Sysname] inqa analyzer

protocol udp-port

Use protocol udp-port to specify a UDP port for communication between the analyzer and collectors.

Use undo protocol udp-port to restore the default.

Syntax

protocol udp-port port-number

undo protocol udp-port

Default

The UDP port number used for communication between the analyzer and collectors is 53312.

Views

Analyzer view

Predefined user roles

network-admin

Parameters

port-number: Specifies a UDP port number in the range of 1024 to 65535.

Usage guidelines

With the analyzer id command configured, iNQA uses the configured analyzer ID and the port number configured by this command to start the UDP server. If the configured UDP port number is used by other services, the UDP server cannot be started, causing the failure of the analyzer. To resolve this issue, modify the UDP port number and then configure the analyzer id command again.

Specify a UDP port number the same as that in the analyzer command in collector instance view. Otherwise, the communication between the collectors and the analyzer fails.

Examples

# Specify UDP port 1024 for communication between the analyzer and collectors.
