delay-measure two-way variation-threshold test-id
Function
The delay-measure two-way variation-threshold test-id command configures variation thresholds for two-way proactive frame delay measurement (DM).
The undo delay-measure two-way variation-threshold test-id command deletes the variation thresholds configured for two-way proactive frame DM.
By default, no variation thresholds are configured for two-way proactive frame DM.
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
delay-measure two-way variation-threshold test-id test-id upper-limit upper-limit lower-limit lower-limit
undo delay-measure two-way variation-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 ranging from 1 to 4294967295. |
| upper-limit upper-limit | Specifies an upper variation threshold for two-way proactive frame DM. | The value is an integer ranging from 0 to 4294967295, in microseconds. |
| lower-limit lower-limit | Specifies a lower variation threshold for two-way proactive frame DM. | The value is an integer ranging from 0 to 4294967295, in microseconds. The lower variation threshold must be less than the upper variation threshold. |
Usage Guidelines
Usage Scenario
To configure upper and lower variation thresholds for two-way proactive frame DM that monitors link quality, run the delay-measure two-way variation-threshold test-id command. After configuring upper and lower variation 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
The configured threshold makes sense only after the proactive measurement is configured.
Example
# Set lower and upper variation thresholds for two-way proactive frame DM in VLAN scenarios to 200 microseconds and 400 microseconds, respectively.
