Programming SR Linux: Management APIs and Automation

Course number: OP00138
Course duration: 3 days (including lectures and hands-on lab exercises)
Price: €2,400

Course overview

This instructor-led, hands-on course will provide a comprehensive understanding of programming APIs (Application Programming Interface) for network automation. This includes gNMI (Network Management Interface), which allows you to configure and monitor every aspect of SR Linux, including streaming telemetry. The JSON-RPC API offers similar configuration and monitoring capabilities; in addition to implementing Ansible modules, it allows SR Linux to be configured as part of an Ansible automation workflow. gNOI (Network Operations Interface) provides a programmatic interface to network operations such as upgrading software, saving SR Linux files and rebooting a device. Finally, gRIBI (Routing Information Base Interface) allows external programs to populate entries directly into the SR Linux routing tables.
