This is dn on a cucsEtherPIoEndPoint object, giving the distinguished-name path of the endpoint sub-object nested under this specific physical port, representing the logical device UCS models as attached at the far end. It distinguishes the endpoint sub-object's own MIT path from the parent port's Dn, useful when a monitoring tool needs to address endpoint-specific properties, such as epCloudType, rather than the port itself. For example, an endPointDn nested one level under a specific FI port's Dn addresses just the endpoint metadata for that port's attached device.
