Programming SR Linux: NetOps Development Kit, CLI Plugins, and Event Handler

Course number: OP00139
Course duration: 3 days (including lectures and hands-on lab exercises)
Price: €2,400

Course overview

This hands-on, instructor-led course defines the programmability and customization capabilities of the Nokia SR Linux. This course covers its various functions such as the Netops Development Kit (NDK) that allows third-party applications to be added to the SR Linux using generic Remote Procedure Call (gRPC) services. This course also covers the Command Line Interface (CLI) plugin framework that allows users to create their own show and tools CLI commands, and the event handler framework that enables programmable actions to react on system events using MicroPython scripts.
