Introduction

Cisco NX-OS software is a data center-class operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. The Cisco NX-OS software provides a robust and comprehensive feature set that meets the requirements of virtualization and automation in mission-critical data center environments. The modular design of the Cisco NX-OS operating system makes zero-impact operations a reality and enables exceptional operational flexibility.

The Cisco NX-OS 7.0(3)F3(3) image is specifically designed to support and bring up the N3K-C36180YC-R switch of the Cisco Nexus 3600 Series platform switches.
