NX-OS exposes a full YANG data model. Tools like Ansible push JSON or XML payloads to configure the entire fabric. Example Ansible task:
Virtual Port Channel (vPC) allows links physically connected to two different Nexus switches to appear as a single Port Channel to a downstream device. This eliminates the blocking states associated with Spanning Tree Protocol (STP), enabling full bandwidth utilization across all uplinks and drastically improving network convergence times. 4.

Cisco's Nexus One initiative represents a fundamental shift in how data center networking is architected and operated. Rather than requiring organizations to choose between different operating models, Nexus One provides an open, unified networking platform that integrates silicon, systems, software, and a single operating model. The philosophy is simple: open choice, no compromises. This eliminates the blocking states associated with Spanning
