By default, the on-demand measurement is disabled.

Format

test start test-session session-id packet-count packet-count [ period period ] [ time-out time-out ]

test start test-session session-id duration duration [ period period ] [ time-out time-out ]

Parameters

Parameter	Description	Value
packet-count packet-count	Indicates the number of packets sent over a test session.	The value is an integer ranging from 100 to 30000. The default value is 100.
period period	Indicates the interval at which packets are sent over a test session.	The value is an enumerated type: 10: Specifies a sending packets interval of 10 ms. 100: Specifies a sending packets interval of 100 ms. 1000: Specifies a sending packets interval of 1000 ms. 30000: Specifies a sending packets interval of 30000 ms. The value is 100 ms by default.
time-out time-out	Indicates the timeout period for response packets.	The value is an integer ranging from 1 to 10, in seconds. The default value is 5.
test-session session-id	Indicates the ID of a test session.	The value is an integer ranging from 1 to 2048.

Usage Guidelines

Usage Scenario

On-demand measurement works in a specified period after being triggered. It can be performed once in the specified period. To implement performance measurement once, run the test start command to enable on-demand measurement. On-demand measurement automatically stops after the specified period elapses or the number of sent packets reaches the specified threshold.

Precautions

On-demand measurement fails in any of the following situations:

On-demand measurement is started when proactive measurement is running.
On-demand measurement is started when board resources are insufficient. If the display twamp-light test-session command output shows inactive in the State option, on-demand measurement fails.

Example

# Set the number of packets sent over a test session to 30000 for on-demand measurement.
