Thank you for your feedback
Synthetic loss measurement is used to measure the frame loss ratios (near-end and far-end) between two MEPs. Measurements and calculations are performed at one end only. You have to set up the SLM instance on the unit that you want to perform and display the SLM measurements.
Note: You must set up a MEP on the remote unit; setting up an SLM instance is optional.
▶ To set up or modify an SLM instance
Access the page SOAM ▶ CFM ▶ SLM ▶ Configuration.
All the existing Synthetic Loss Measurement Instances are displayed.Click Add to create an SLM instance or click the SLM instance index to edit an existing SLM instance.
Complete the required fields, then click Apply.
For more information on specific parameters, refer to the following table.
Synthetic Loss Message Configuration (SOAM ▶ CFM ▶ SLM ▶ Configuration)
| Parameter | Description |
|---|---|
| Index | The index of the SLM instance |
| Name SLM Name | The name of the SLM instance. |
| MEP Index MEP idx | The index assigned to the MEP |
| MEPID | The local Maintenance association End Point Identifier |
| Remote MEPID R-MEPID | The remote Maintenance association End Point Identifier |
| Priority | Priority value used in VLAN tags, if present, in the transmitted frame. |
| Interval | The time, expressed in milliseconds, at which this SLM instance issues SLM frames. Possible values are: 10 , 100, 1000 and 10000 milliseconds. Default: 1000 milliseconds |
| Enable State | The state of the SLM instance. When enabled, SLM frames are sent at the specified interval. Disabled by default. |
| Reference Period | Reference period, expressed in minutes, for the SLM instance. Range: 1 to 1440 minutes; default: 15 minutes. |
| Near-End Threshold | The frame loss threshold for near-end packet loss, expressed as a percentage. |
| Far-End Threshold | The frame loss threshold for far-end packet loss, expressed as a percentage. |
