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.

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

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

HTTPS 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 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 client performs only one lookup operation.

Usage guidelines

Upon receiving a response packet, the NQA client looks up the target payload content 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 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.

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.

Examples

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

Parameters

get: Gets a file from the FTP server.

put: Transfers a file to the FTP server.

Usage guidelines

When you perform the put operation with the filename command configured, make sure the file exists on the NQA client.

If you get a file from the FTP server, make sure the file specified in the URL exists on the FTP server. The NQA client does not save the file obtained from the FTP server.

Use a small file for the FTP operation. A big file might result in transfer failure because of timeout, or might affect other services for occupying much network bandwidth.

Examples

# Set the operation type to put for the FTP operation.

jitter-sd: Specifies source-to-destination jitter of each probe packet as the monitored element.

threshold-type: Specifies a threshold type.

accumulate accumulate-occurrences: Checks the total number of threshold violations in the operation. The value is in the range of 1 to 14999.

average: Checks the average one-way jitter.

threshold-value: Specifies threshold range in milliseconds.

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

Parameters

item-number: Assigns an ID to the reaction entry, in the range of 1 to 10.

owd-ds: Specifies the destination-to-source delay of each probe packet as the monitored element.

owd-sd: Specifies the source-to-destination delay of each probe packet as the monitored element.

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.

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.

No actions can be configured for a reaction entry of monitoring one-way delays. To display the monitoring results and statistics, use the display nqa reaction counters and display nqa statistics commands.

Examples

# Create reaction entry 1 for monitoring the destination-to-source delay of every UDP jitter packet, 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. The destination-to-source delay is calculated after the response to the probe packet arrives. If the delay exceeds the upper limit, the state of the reaction entry is set to over-threshold. If it is below the lower limit, the state is set to below-threshold. Once the state of the reaction entry changes, a trap message is generated and sent to the NMS.

Parameters

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. The system counts the total number of probe failures in an operation. If the number reaches or exceeds the value for the cumulate-probe-failures argument, a trap is sent for the operation failure.

cumulate-probe-failures: Specifies the total number of probe failures in an operation. The value range is 1 to 15.

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.

tos tos: Specifies the ToS value in the IP header for reply packets. The value range for this 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 the IP address 169.254.10.2 and port 9000.
