The value of sdpBindEthCfmVMepFilter specifies whether
ETH-CFM PDUs egressing the sap or sdp-binding at the same
level or lower than that of the configured service MEP
(the virtual MEP) should be discarded or continue to
egress.
Only PDUs that were originated from the virtual MEP or from
the networks side of the service will be affected, local
down MEP ETH-CFM transmission are not. When set to 'true'
ETH-CFM PDUs with the same or lower level as the virtual
MEP will be discarded. When set to 'false', egressing
ETH-CFM PDUs will pass freely as per the existing ETH-CFM
configuration.
