The following acronyms are used in this module: - MEP: Maintenance End Point - MEPID: Maintenance End Point Identifier - CC: Continuity Check - CCDB: Continuity Check Database - SVLAN: Service Provider Virtual Local Area Network - VLAN: Virtual Local Area Network - CLI: Command Line Interface. - OAM: Operations Administration and Management.
