For more information on specific parameters, refer to the following table. **Packet Loss Configuration (SOAM ▶ CFM ▶ Packet Loss ▶ Configuration)** | Parameter | Description | | --- | --- | | Index | The packet loss instance unique identifier | | PL Name Name | The name of the packet loss instance. | | MEP Index MEP idx | The index assigned to the Maintenance association End Point | | MEPID | The local Maintenance association End Point Identifier | | Remote MEPID R-MEPID | The remote Maintenance association End Point Identifier ***Note**: A peer MEP should have the sequence number enabled to allow a local MEP to perform CCM-based packet loss measurements.* | | Priority | The Priority value to be used in VLAN tags, if present, in the transmitted frame. Same as MEP's CCM priority. | | Interval | The Interval between packet loss measurements. This value is inherited from the MA/MEG's CCM interval. | | Enable | Enables packet loss measurements. | | Reference Period | Specify the reference period in minutes. | | Threshold | Specify (as a percentage) the maximum ratio of packets lost allowed before issuing an alarm during the reference period. | **© 2026 Cisco and/or its affiliates.
