For VNF Fault Management stage 2 solution over Itf-N, the Alarm IRP IS is applicable. The overall architectural feature of Alarm IRP is specified in TS 32.111-2 [2]. The Alarm IRP IS defines the semantics of alarms and the interactions visible across the reference point in a protocol neutral way. It defines the semantics of the operations and notifications visible in the Alarm IRP. It does not define the syntax or encoding of the operations, notifications and their parameters. For the purpose of notification, Notification IRP [3] is needed.
