Overview
The OcNOS DC Layer 2 Guide provides a comprehensive reference for the switching and Ethernet capabilities supported in OcNOS for modern Data Center CLOS fabrics. It consolidates all Layer 2 protocols into a single resource, focusing on bridging, loop prevention, and high-performance capabilities essential for AI/ML and multi-tenant environments, such as lossless Ethernet via Data Center Bridging (DCB).
Each feature includes conceptual overviews, configuration procedures, topology examples, and command references. This guide explains how Layer 2 functions operate within OcNOS to ensure low latency in high-density data center architectures.
