What is dot1agCfmMepXconCcmDefect?

Indicates that this MEP is receiving a stream of CCMs from a MEP that may actually belong to a different Maintenance Association, a sign of a possible cross-connection error between service instances. This is one of the more serious CFM defects, since it can indicate two customers' traffic paths have been misconfigured together.

Examples
