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 configure the advantage factor. When the system calculates the ICPIF value, the specified advantage factor is subtracted to modify ICPIF and MOS values for voice quality evaluation.

Examples

# Set the advantage factor to 10 for the voice operation.

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 the payload size as 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

data-size

Use data-size to configure the size of the payload in each ICMP echo request of the ICMP echo and path jitter operations, or in each UDP packet of the UDP echo, UDP jitter, and voice operations.

Use undo data-size to restore the default.

Syntax

data-size size

undo data-size

Default

The default payload size of a probe packet for different operations is described in Table 1.

Table 1 Default payload size of a probe packet

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 template view

TCP template view

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 between the expected data and the actual data. The value range for the number argument is 0 to 1000, and the default value is 0.

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 template, the NQA client checks for the expected data if the response contains the Content-Length header.

· For features that use the TCP 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

status-list: Specifies a space-separated list of up to 10 status code items. Each item specifies a status code or a range of status codes in the form of status-num1 to status-num2. The value ranges for both the status-num1 and status-num2 arguments are 0 to 999. The value for the status-num2 argument must be equal to or greater than the value for the status-num1 argument.

Usage guidelines

The status code of the HTTP packet is a three-digit field in decimal notation and it includes the status information for the HTTP server. The first digit defines the class of response, and the last two digits do not have any categorization role.

Examples

# In HTTP template view, set the expected status codes to 200, 300, and 400 to 500.

Parameters

ip-address&<1-8>: Specifies a space-separated list of up to eight IP addresses. Each IP address represents a hop on the path.

Usage guidelines

The path jitter operation first uses tracert to detect each hop to the destination. It then sends ICMP echo requests to measure the delay and jitters from the source to each node. If multiple routes exist between the source and destination, the operation uses the path specified by using lsr-path command.

Examples

# Specify 10.1.1.20 and 10.1.2.10 as the hops on the LSR path for the path jitter operation.

<Sysname> system-view

[Sysname] nqa entry admin test

Parameters

times: Specifies the probe times in the range of 1 to 15.

Usage guidelines

The following describes how NQA performs different types of operations:

· A TCP or DLSw operation sets up a connection.

· A 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 operation 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 path jitter operation is accomplished in the following steps:

a. The operation uses tracert to obtain the path from the NQA client to the destination. A maximum of 64 hops can be detected.

b. The NQA client sends ICMP echo requests to each hop along the path. The number of ICMP echo requests is set by using the probe packet-number command.

· A UDP tracert operation sends a UDP packet to each hop along the path per probe. Use the probe count command to set the number of probes performed on each hop.

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 and path jitter operations. Each of these operations performs only one probe.

Before the NQA operation starts, the initial state of the reaction entry is invalid. After the operation, the consecutive probe duration is checked against the threshold range. If the total number of consecutive threshold violations reaches or exceeds 10, the state of the entry is set to over-threshold. If it is below the lower threshold, the state of the entry is set to below-threshold. Once the state of the reaction entry changes, a trap message is generated and sent to the NMS.

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 a VPN 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 for the tos argument 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 and port number 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 and respond to IP address 169.254.10.2 and port 9000.
