This attribute specifies whether the Loss Measurement session is enabled. The value 'true' indicates the Loss Measurement session is enabled and SOAM PDUs are sent and/or measurements are collected when the session is running according to the scheduling objects (start time, stop time, etc.). The value 'false' indicates the Loss Measurement session is disabled and SOAM PDUs are not sent and/or measurements collected. For a Loss Measurement session to be removed the row is deleted in order to release internal resources. This object can written/modified after row creation time. If the LM session is enabled it resumes after shutdown/restart. This object does not affect whether the single-ended responder is enabled or not, which is enabled or disabled by the osSoamPmFlowLmSinglEndResponder and osSoamPmFlowSlmSinglEndResponder objects.
