MEP for an Ethernet Private Line Service

Configuring Maintenance End Points for an EPL service

This use case article describes the configuration of the MEP for an Ethernet Private Line service.

• 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.
