loss-measure single-ended-synthetic local-ratio-threshold test-id
Function
The loss-measure single-ended-synthetic local-ratio-threshold test-id command configures local packet loss ratio thresholds for single-ended synthetic loss measurement (SLM).
The undo loss-measure single-ended-synthetic local-ratio-threshold test-id command deletes the local packet loss ratio thresholds configured for single-ended SLM.
By default, no local packet loss ratio thresholds are configured for single-ended SLM.
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 local-ratio-threshold test-id test-id upper-limit upper-limit lower-limit lower-limit
undo loss-measure single-ended-synthetic local-ratio-threshold test-id test-id [ upper-limit upper-limit lower-limit lower-limit ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| test-id | Specifies the ID of a test instance. |
The value is an integer that ranges from 1 to 4294967295. |
| upper-limit upper-limit | Specifies an upper local packet loss ratio threshold for single-ended SLM. | The value is a string of 1 to 8 characters in the format of xxx.xxxx, in percentages. |
| lower-limit lower-limit | Specifies a lower local packet loss ratio threshold for single-ended SLM. | The value is a string of 1 to 8 characters in the format of xxx.xxxx, in percentages. The lower local packet loss ratio threshold must be less than the upper local packet loss ratio threshold. |
Usage Guidelines
Usage Scenario
On a point-to-multipoint or multipoint-to-multipoint network, run the loss-measure single-ended-synthetic local-ratio-threshold test-id command to configure local packet loss ratio thresholds for single-ended SLM. After configuring upper and lower local packet loss ratio thresholds, you can obtain data (such as the number of times that a threshold-crossing event occurs) within a sampling period to monitor network performance.
Prerequisites
A test instance has been created using the test-id command in the MA view.
Precautions
Thresholds can be configured only for proactive single-ended SLM and cannot be configured for on-demand single-ended SLM.
Example
# Set lower and upper local packet loss ratio thresholds for single-ended SLM to 10.1111 and 11.1111 respectively for test instance 1.
