loss-measure single-ended-synthetic continual send
Function
The loss-measure single-ended-synthetic continual send command enables proactive single-ended synthetic loss measurement (SLM).
The undo loss-measure single-ended-synthetic continual send command disables proactive single-ended SLM.
By default, proactive single-ended SLM is disabled.
Only the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.
Format
loss-measure single-ended-synthetic continual send test-id test-id interval { 3.3 | 10 | 100 | 1000 | 10000 } [ sending-count count-value ] [ time-out timeout ] [ packet-size packet-size ]

Parameters
| Parameter | Description | Value |
|---|---|---|
| test-id test-id | Specifies the ID of a test instance. | The value is an integer that ranges from 1 to 4294967295. |
| interval { 3.3 | 10 | 100 | 1000 | 10000 } | Specifies the interval at which SLM frames are sent. | Enumerated value, in milliseconds:
|
| sending-count count-value | Specifies the times that SLM frames are sent within each measurement period. | The value is an integer ranging from 1 to 1000. The default value is 10. |
| timeout timeout | Specifies the timeout period during which the device waits for a response. | The value is an integer ranging from 1 to 10, in seconds. The default value is 5s. |
| packet-size packet-size | Specifies the size of the SLM frames. | The value is an integer ranging from 64 to 1518, in bytes. The default value is 64. |
Usage Guidelines
Usage Scenario
To collect accurate frame loss statistics on a point-to-multipoint network, run the loss-measure single-ended-synthetic continual send command to configure proactive single-ended SLM.
Prerequisites
A test instance has been created using the test-id command in the MA view.
Example
# Configure SLM with test id of 1 and statistics collection interval of 10s.
