An osSoamLmSessionStartStopAlarm notification is sent when the state of osSoamLmCfgSessionStatus changes. The management entity that receives the notification can identify the system from the network source address of the notification, and can identify the individual PM session reporting the start/stop by the indices in the OID osSoamLmCfgSessionStatus, including osEthServId, osEthServFlowId, and osSoamLmCfgIndex. An agent is not to generate more than one osSoamLmSessionStartStopAlarm 'notification-event' in a given time interval per LM session as specified by the osSoamPmNotifCfgAlarmInt. A 'notification-event' is the transmission of a single notification to a list of notification destinations. If additional operational state changes occur within the osSoamPmNotifCfgAlarmInt period, then notification generation for these changes are be suppressed by the agent until the current alarm interval expires. At the end of an alarm interval period, one notification-event is generated if any operational state changes occurred since the start of the alarm interval period. In such a case, another alarm interval period is started right away.
