Configuring Maintenance End Points for an EPL service
This use case article describes the configuration of the MEP for an Ethernet 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.
- Support for Multiple Maintenance Domain Level with MD Level of UP MEP being higher than the MD Level of Down MEP.
- Functionality of Continuity Check (CC – for intervals of 3.3ms and 1 second), Loopback (LB), and Link Trace (LT)
- Support for Cross-connect defect (DefXconCMM), Error-CCM defect (DefErrorCCM), Remote CCM defect (DefRemoteCCM), and RDI defect (DefRDICCM)
- MAC Status defect (DefMACstatus) is not supported, due to its capability not being supported in Marvell chipset.
