The document discusses configuring Broadcom-based network switches using OpenNSL. It provides an overview of the Open Compute Project (OCP), Facebook's Wedge switch hardware, the Open Network Linux (ONL) operating system, and the Broadcom Trident2 chip. It then demonstrates how to perform basic L2 switching and L3 routing functions using the OpenNSL API, such as learning MAC addresses, forwarding traffic, creating IP interfaces, and adding routes. OpenNSL provides an open-source hardware abstraction layer for programming Broadcom switching ASICs.
