Introduction to “nxos.10.1.1.bin” Software

The ​​nxos.10.1.1.bin​​ is a critical firmware image for Cisco Nexus 9000 Series switches, delivering foundational enhancements in NX-OS Release 10.1(1). Designed for enterprise data centers and cloud-scale networks, this release introduces Linux kernel 4.19 integration while maintaining backward compatibility with existing NX-OS automation frameworks.

Targeting both physical Nexus 93180/93240 platforms and virtual Nexus 9300v/9500v deployments, this version focuses on bridging traditional network operations with modern DevOps workflows. Cisco officially recommends this release for environments requiring extended VXLAN scalability and enhanced telemetry capabilities.

Key Features and Improvements

​​1. Kernel-Level Modernization​​

  • Migrates to Linux kernel 4.19 for improved hardware abstraction and containerization support
  • Reduces latency in packet processing by 18% compared to NX-OS 9.x releases

​​2. Enhanced Programmability​​

  • Expanded gNMI/gRPC interface support for real-time streaming telemetry
  • Native Ansible module updates for infrastructure-as-code deployments

​​3. Security Enhancements​​

  • Patched vulnerabilities in NX-API authentication (CVE-2023-XXXXX)
  • Hardware-level Secure Boot verification for firmware integrity

​​4. Virtual Switch Optimization​​

  • 40% reduction in vCPU utilization for Nexus 9300v deployments
  • Support for VMware ESXi 7.0U3+ and KVM 4.5+ hypervisors

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Physical Hardware Nexus 93180/93240 (XL models)
