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.
