NETCONF supports event notifications through a subscription model. The operation used to establish a notification subscription is create-subscription. When a client sends this operation, it can specify the stream and optional filters that determine which notifications are delivered to that NETCONF session. This is why create-subscription is the operation associated with session-specific notification filtering. The commit operation is used with the candidate configuration datastore to apply configuration changes to the running datastore; it does not create a telemetry or event subscription. The notification element is the message sent by the server after a subscription exists, not the operation used to create one. Logging is not a NETCONF operation in the protocol operation set. In Cisco model-driven management designs, NETCONF provides structured configuration and operational access using YANG data models, while notifications allow the management station to consume specific events without relying on repeated screen scraping or broad polling.
Therefore, the correct operation for creating filtering specific to session notifications is create-subscription.
