4 entPhysicalContainsEntry 1.3.6.1.2.1.47.1.3.3.1 entPhysicalContainsEntry 1.3.6.1.2.1.47.1.3.3.1 Indexes A single container / containee relationship. 1: entPhysicalIndex 2: entPhysicalChildIndex entPhysicalChildIndex 1.3.6.1.2.1.47.1.3.3.1.1 The value of entPhysicalIndex for the contained physical entity. General Group entLastChangeTime 1.3.6.1.2.1.47.1.4.1 The value of sysUpTime at the time a conceptual row is created, modified, or deleted in any of the following tables: • entPhysicalTable • entLogicalTable • entLPMappingTable • entAliasMappingTable • entPhysicalContainsTable Entity MIB Trap This section lists the entityMIBTrap objects. entConfigChange 1.3.6.1.2.1.47.2.0.1 An entConfigChange notification is generated when the value of entLastChangeTime changes. It can be utilized by an NMS to trigger logical/physical entity table maintenance polls. An agent should not generate more than one entConfigChange notification event in a given time interval (five seconds is the suggested default). A notification event is the transmission of a single trap or inform PDU to a list of notification destinations. If additional configuration changes occur within the throttling period, then notification events for these changes should be suppressed by the agent until the current throttling period expires. At the end of a throttling period, one notification event should be generated if any configuration changes occurred since the start of the throttling period; in such a case, another throttling period is started right away. An NMS should periodically check the value of entLastChangeTime to detect any missed entConfigChange notification events, for example, due to throttling or transmission loss. 4-18 Fabric OS MIB Reference Publication Number: 53-1000241-01
