NQA commands

NQA client commands

advantage-factor

Use advantage-factor to set the advantage factor to be used for calculating Mean Opinion Scores (MOS) and Calculated Planning Impairment Factor (ICPIF) values.

Use undo advantage-factor to restore the default.

Syntax

advantage-factor factor

undo advantage-factor

Default

The advantage factor is 0.

Views

Voice operation view

Predefined user roles

network-admin

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

codec-type

Use codec-type to configure the codec type for the voice operation.

Use undo codec-type to restore the default.

Syntax

codec-type { g711a | g711u | g729a }

undo codec-type

Default

The codec type for the voice operation is G.711 A-law.

Views

Voice operation view

Predefined user roles

network-admin

Parameters

g711a: Specifies G.711 A-law codec type.

g711u: Specifies G.711 µ-law codec type

g729a: Specifies G.729 A-law codec type.

Examples

# Set the codec type to g729a for the voice operation.

<Sysname> system-view

[Sysname] nqa entry admin test

[Sysname-nqa-admin-test] type voice

[Sysname-nqa-admin-test-voice] codec-type g729a

community read

Use community read to specify the community name for the SNMP operation.

Use undo community read to restore the default.

Syntax

community read { cipher | simple } community-name

undo community read

Default

The SNMP operation uses the community name public.

Views

SNMP operation view

Predefined user roles

network-admin

Parameters

cipher: Specifies a community name in encrypted form.

simple: Specifies a community name in plaintext form. For security purposes, the community name specified in plaintext form will be stored in encrypted form.

community-name: Specifies the community name. Its plaintext form is a case-sensitive string of 1 to 32 characters. Its encrypted form is a case-sensitive string of 33 to 73 characters.

Usage guidelines

You must specify the community name for the SNMP operation when both of the following conditions exist:

·          The SNMP operation uses the SNMPv1 or SNMPv2c agent.

·          The SNMPv1 or SNMPv2c agent is configured with a read-only or read-write community name.

The specified community name must be the same as the community name configured on the SNMP agent.

The community name configuration is not required if the SNMP operation uses the SNMPv3 agent.

For more information about SNMP, see "Configuring SNMP."

Examples

# Specify readaccess as the community name for the SNMP operation.

<Sysname> system-view

[Sysname] nqa entry admin test

[Sysname-nqa-admin-test] type snmp

[Sysname-nqa-admin-test-snmp] community read simple readaccess

data-fill

Use data-fill to configure the payload fill string for probe packets.

Use undo data-fill to restore the default.

Syntax

data-fill string

undo data-fill

Default

The default payload fill string is the hexadecimal string 00010203040506070809.

Views

ICMP/UDP echo operation view

Path jitter/UDP jitter/voice operation view

ICMP/TCP/UDP template view

Predefined user roles

network-admin

Parameters

string: Specifies a case-sensitive string of 1 to 200 characters.

Usage guidelines

If the payload length is smaller than the string length, only the first part of the string is filled. For example, if you configure the string as abcd and set the payload size to 3 bytes, abc is filled.

If the payload length is greater than the string length, the system fills the payload with the string cyclically until the payload is full. For example, if you configure the string as abcd and the payload size as 6 bytes, abcdab is filled.

How the string is filled depends on the operation type.

·          For the ICMP echo operation, the string fills the whole payload of an ICMP echo request.

·          For the UDP echo operation, the first five bytes of the payload of a UDP packet are for special purpose. The string fills the remaining part of payload.

·          For the UDP jitter operation, the first 68 bytes of the payload of a UDP packet are for special purpose. The string fills the remaining part of the payload.

·          For the voice operation, the first 16 bytes of the payload of a UDP packet are for special purpose. The string fills the remaining part of the payload.

·          For the path jitter operation, the first four bytes of the payload of an ICMP echo request are for special purpose. The string fills the remaining part of payload.

Examples

# Specify abcd as the payload fill string for ICMP echo requests.

<Sysname> system-view

[Sysname] nqa entry admin test

[Sysname-nqa-admin-test] type icmp-echo

[Sysname-nqa-admin-test-icmp-echo] data-fill abcd

display nqa statistics

Use display nqa statistics to display NQA operation statistics.

Syntax

display nqa statistics [ admin-name operation-tag ]

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

admin-name operation-tag: Specifies an NQA operation by its administrator name and operation tag. The admin-name argument represents the name of the administrator who creates the NQA operation. The operation-tag argument represents the operation tag. Each of the arguments is a case-insensitive string of 1 to 32 characters that cannot contain hyphens (-). If you do not specify an NQA operation, the command displays statistics for all NQA operations.

Usage guidelines

The statistics are generated after the NQA operation completes. If you execute the display nqa statistics command before the operation completes, the statistics are displayed as all 0s.

If a reaction entry is configured, the command displays the monitoring results of the reaction entry in the period specified by the statistics internal command. The result fields display hyphens (-) in one of the following conditions:

·          The threshold type is average value.

·          The monitored performance metric is ICPIF or MOS for the voice operation.

‌This command is not available for the UDP tracert operation.

expect data

Use expect data to configure the expected data.

Use undo expect data to restore the default.

Syntax

expect data expression [ offset number ]

undo expect data

Default

No expected data is configured.

Views

HTTP/HTTPS/TCP/UDP template view

Predefined user roles

network-admin

Parameters

expression: Specifies the expected data, a case-sensitive string of 1 to 200 characters.

offset number: Specifies the offset in bytes after which the first match operation starts. The value range for the number argument is 0 to 1000, and the default value is 0. If you do not specify an offset, the match operation starts from the beginning byte of the payload.

Usage guidelines

Upon receiving a response packet, the NQA client examines the target payload for the expected data.

·          If a match is found, the NQA client verifies the NQA destination device as legal.

·          If no match is found, the NQA client looks up the entire payload for a match. If no match is found again, the NQA destination device is verified as illegal. The NQA client does not perform the second round if no offset is specified. It verifies the NQA destination as illegal directly if no match is found for the first round.

Expected data check takes place in the following conditions:

·          For features that use the HTTP or HTTPS template, the NQA client checks for the expected data if the response contains the Content-Length header.

·          For features that use the TCP or UDP template, the NQA client checks for the expected data if the data-fill command is configured.

The first five bytes of the UDP packet payload identify the probe packet type. The start byte of the offset is the sixth byte of the UDP payload.

Examples

# In HTTP template view, set the expected data to welcome!.

<Sysname> system-view

[Sysname] nqa template http httptplt

[Sysname-nqatplt-http-httptplt] expect data welcome!

Parameters

admin-name operation-tag: Specifies an NQA operation by its administrator name and operation tag. The admin-name argument represents the name of the administrator who creates the NQA operation. The operation-tag argument represents the operation tag. Each of the arguments is a case-insensitive string of 1 to 32 characters that cannot contain hyphens (-).

start-time: Specifies the start time and date of the NQA operation.

hh:mm:ss: Specifies the start time of an NQA operation.

yyyy/mm/dd: Specifies the start date of an NQA operation. The default value is the current system time, and the value for the yyyy argument is in the range of 2000 to 2035.

mm/dd/yyyy: Specifies the start date of an NQA operation. The default value is the current system time, and the value for the yyyy argument is in the range of 2000 to 2035.

now: Starts the operation immediately.

lifetime: Specifies the duration of an operation.

lifetime: Specifies the duration of an operation in seconds. The value range is 1 to 2147483647.

forever: Performs the operation until you stop it by using the undo nqa schedule command.

recurring: Runs the operation automatically at the start time and for the specified duration. If you do not specify this keyword, the NQA operation is performed only once at the specified date and time.

Usage guidelines

The NQA operation works between the specified start time and the end time (the start time plus operation duration). If the specified start time is ahead of the system time, the operation starts immediately. If both the specified start time and end time are ahead of the system time, the operation does not start. To display the current system time, use the display clock command.

You cannot enter the view of a scheduled NQA operation. If you want to enter such view, use the undo nqa schedule command to stop the NQA operation first.

Specify a lifetime long enough for an operation to complete.

Examples

# Schedule the operation with administrator name admin and operation tag test to start on 08:08:08 2008/08/08 and last 1000 seconds.

Parameters

times: Specifies the probe times.

·          For the UDP tracert operation, this argument specifies the times of probes to each hop along the path. The value range for this argument is 1 to 10.

·          For other types of operations, this argument specifies the times of probes to the destination per operation. The value range for this argument is 1 to 15.

Usage guidelines

The following describes how NQA performs different types of operations:

·          A TCP or DLSw operation sets up a connection.

·          An ICMP jitter or UDP jitter operation sends a number of probe packets. The number of probe packets is set by using the probe packet-number command.

·          An FTP operation uploads or downloads a file.

·          An HTTP operation gets a Web page.

·          A DHCP operation gets an IP address through DHCP.

·          A DNS operation translates a domain name to an IP address.

·          An ICMP echo sends an ICMP echo request.

·          A UDP echo operation sends a UDP packet.

·          An SNMP operation sends one SNMPv1 packet, one SNMPv2c packet, and one SNMPv3 packet.

·          A UDP tracert operation determines the routing path from the source to the destination. The number of probe packets sent to each hop is set by using the probe count command.

·          A frame loss, latency, or throughput operation sends probe frames to the destination device to test the frame loss ratio, latency, or throughput of the network.

If an operation is to perform multiple probes, the NQA client starts a new probe in one of the following conditions:

·          The NQA client receives responses to packets sent in the last probe.

·          The probe timeout time expires.

This command is not available for the voice or path jitter operations. Each of these operations performs only one probe.

threshold-type: Specifies a threshold type.

accumulate accumulate-occurrences: Checks the total number of threshold violations. Available value ranges include:

·          1 to 15000 for the ICMP jitter and UDP jitter operations.

·          1 to 60000 for the voice operation.

average: Checks the packet average round-trip time.

threshold-value: Specifies threshold range in milliseconds.

upper-threshold: Specifies the upper limit in the range of 0 to 3600000.

lower-threshold: Specifies the lower limit in the range of 0 to 3600000. It must not be greater than the upper limit.

action-type: Specifies what action to be triggered. The default action is none.

none: Specifies the action of displaying results on the terminal display.

trap-only: Specifies the action of displaying results on the terminal display and meanwhile sending SNMP trap messages to the NMS.

Usage guidelines

You cannot edit a reaction entry after it is created. To change the attributes in a reaction entry, use the undo reaction command to delete the entry, and then configure a new one.

Only successful probe packets are monitored. Statistics about failed probe packets are not collected.

Examples

# Create reaction entry 1 for monitoring the average round-trip time of UDP jitter probe packets, and set the upper limit to 50 milliseconds and lower limit to 5 milliseconds. Before the NQA operation starts, the initial state of the reaction entry is invalid. After the operation, the average packet round-trip time is checked. If it exceeds the upper limit, the state is set to over-threshold. If it is below the lower limit, the state is set to below-threshold. Once the reaction entry state changes, a trap message is generated and sent to the NMS.

Parameters

path-change: Sends a trap when the UDP tracert operation detects a different path to the destination.

probe-failure consecutive-probe-failures: Sends a trap to the NMS if the number of consecutive probe failures in an operation is greater than or equal to consecutive-probe-failures. The value range for the consecutive-probe-failures argument is 1 to 15. The system counts the number of consecutive probe failures for each operation, so multiple traps might be sent.

test-complete: Sends a trap to indicate that the operation is completed.

test-failure: Sends a trap when an operation fails. For operations other than UDP tracert operation, the system counts the total number of probe failures in an operation. If the number reaches or exceeds the value for the accumulate-probe-failures argument, a trap is sent for the operation failure.

accumulate-probe-failures: Specifies the total number of probe failures in an operation. The value range is 1 to 15. This argument is not supported by the UDP tracert operation.

Usage guidelines

The ICMP jitter, UDP jitter, and voice operations support only the test-complete keyword.

The following parameters are not available for the UDP tracert operation:

·          The probe-failure consecutive-probe-failures option.

·          The accumulate-probe-failures argument.

Parameters

ip-address: Specifies the IP address for the TCP listening service.

port-number: Specifies the port number for the TCP listening service, in the range of 1 to 65535.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the NQA server listens on a public IP address.

tos tos: Specifies the ToS value in the IP header for reply packets. The value range is 0 to 255, and the default value is 0.

Usage guidelines

Use this command on the NQA server only for the TCP operation.

When you configure the IP address and port number for a TCP listening service on the NQA server, follow these restrictions and guidelines:

·          The IP address, port number, and VPN instance must be unique on the NQA server and match the configuration on the NQA client.

·          The IP address must be the address of an interface on the NQA server.

·          To ensure successful NQA operations and avoid affecting existing services, do not configure the TCP listening service on well-known ports from 1 to 1023.

Examples

# Configure a TCP listening service to enable the NQA server to listen to port 9000 on the IP address 169.254.10.2.
