# View Synthetic Loss Measurement Results

**To view synthetic loss measurement results details**

1. Access the page **SOAM ▶ CFM ▶ SLM ▶ Results**. A summary of results for all SLM instances is displayed.
2. Click the **Index** of the SLM instance for which you want to view the synthetic loss measurements.

For more information on specific parameters, refer to the following table.

**SLM Results (SOAM ▶ CFM ▶ SLM ▶ Results)**

| Parameter | Description |
| --- | --- |
| Index | The index of the SLM instance |
| Name | The name of the SLM instance |
| MEP Index | The index assigned with the Maintenance association End Point |
| MEPID | The local Maintenance association End Point Identifier |
| Remote MEPID R-MEPID | The remote Maintenance association End Point Identifier. |
| Priority | The priority value to be used in VLAN tags, if present, in the transmitted frame |
| Period | The number of periods that have elapsed since measurement started The previous period is indicated in **Period Time**. **Continuous Results** in the section below gives the packet loss since the last time the statistics were cleared. |
| Period Time | The time when the current period results were moved to the previous period results |
| A Near-End Alarm | The state of the near-end SLM alarm |
| A Far-End Alarm | The state of the far-end SLM alarm |
| SLM Sent | The number of synthetic loss messages sent |
| SLR Received | The number of synthetic loss replies received |
| Remote SLM Received | The number of synthetic loss messages received by the remote MEP |
| Near-End Packets Lost | The number of packets lost at the near end |
| Far-End Packets Lost | The number of packets lost at the far end |
| Near-End Pkt-Loss Ratio NE Loss % | Near-end loss ratio The ratio of packets lost in a near-end network |
| Far-End Pkt-Loss Ratio FE Loss % | Far-end loss ratio The ratio of packets lost in a far-end network |
| Number of Gaps Nbr Gaps | The total number of gaps that have been detected from the sequence of packets that were received during the interval ***Note**: This counter is reset to zero at the beginning of each period.* |
| Largest Gap Size Largest Gap | The longest uninterrupted sequence of missing packets that was detected during the period. Expressed in packets ***Note**: This counter is reset to zero at the beginning of each period.* |
| Operational Status | The SLM operational status code. Valid values are: - **INAC**: Feature is inactive - **UNLK**: Remote device is unlinked - **WAPP**: Waiting for an application that supports the SLM to become active - **PROG**: Remote device is currently being programmed - **FAIL**: Remote device has encountered a failure - **ACT**: Remote device is active and fully functional |
