MEP for an Ethernet Virtual Private Line Service
Configuring Maintenance End Points for an EVPL service
This use case article describes the configuration of the MEP for an Ethernet Virtual Private Line service.
Note: The Maintenance Domain and Maintenance Association must be configured prior to the configuration of the MEP.
- Configuring of S-VLAN-aware Down MEP on NNI Port and S-VLAN-aware UP MEP on UNI Port for each of S-VLAN in EVPL service.
Note: All other CFM functionalities will be supported as described in MEP for an EPL service.
