About Programmability
• RESTCONF— Uses structured data (XML or JSON) and YANG to provide a REST-like APIs,
enabling you to programmatically access different network devices. RESTCONF APIs use HTTPs
methods.
• YANG—A data modeling language that is used to model configuration and operational features on
the switch. YANG determines the scope and the kind of functions that can be performed by
NETCONF and RESTCONF APIs. The following data models are supported:
– The ned.yang model—A Cisco-specific configuration data model that enables to you perform
write (SET) operations.
– The Operational Data Manager (ODM)—Enables you to read operational state data (GET
operations) using YANG models.
Figure 6-1 shows how the different components of Programmability come together.
