Introduction to nxos64-cs.10.5.2.F.bin Software

The ​​nxos64-cs.10.5.2.F.bin​​ is the primary NX-OS software image for Cisco Nexus 9000 Series switches, including 9300-EX, FX, FX2, FX3, and GX platform models. This release introduces architectural optimizations for hyperscale data center deployments, supporting advanced telemetry streaming and hardware-assisted security features documented in Cisco’s Q2 2025 release notes.

Compatible with spine-leaf architectures requiring 400G port density, the software enables unified management of Layer 2/Layer 3 protocols across physical and virtualized infrastructure. Cisco officially validates this build for deployments using VXLAN EVPN multi-site topologies with Nexus 9500-R series chassis.

Key Features and Improvements

Version 10.5(2)F delivers:

  1. ​​Distributed Buffer Management​​ – Reduces microburst-induced packet loss by 42% in 400G oversubscription scenarios
  2. ​​MACsec-256 Encryption​​ – Extends hardware-accelerated encryption to 100/400G interfaces on 9300-GX platforms
  3. ​​Telemetry Enhancements​​ – Supports gNMI/gRPC streaming at 10Hz sampling rates for real-time fabric monitoring
  4. ​​IPv6 Host Routing Scale​​ – Doubles ND entries to 512K per line card in LPM dual-host mode
  5. ​​FCoE Optimization​​ – Reduces NPIV login latency by 35% in storage-area network configurations

Technical documentation highlights improved TCAM utilization for ACL policies and automated EPLD firmware validation during ISSU upgrades.

Compatibility and Requirements

Supported Hardware Minimum NX-OS Version Memory Requirement
Nexus 9300-GX 10.3(1)F 32GB DRAM
Nexus 9500-R 9.3(5) 64GB per supervisor
Nexus 9300-FX3 10.2(2)F 16GB DRAM

​​Critical Compatibility Notes​​:

  • Requires BIOS version 6.1.2+ for 9300-GX switches
  • Incompatible with 32-bit NX-OS configurations (post-2019 hardware only)
  • Mandatory CMPv2 protocol for SNMPv3 implementations

Introduction to nexus9300v.9.3.5.ova Software

The ​​nexus9300v.9.3.5.ova​​ virtual appliance enables lab simulation of Cisco Application Centric Infrastructure (ACI) environments, replicating Nexus 9300 Series switch behavior in VMware ESXi 7.0+ and KVM hypervisors. This release aligns with ACI 9.3(5) fabric requirements, supporting advanced policy modeling for multi-tenant cloud architectures.

Validated for use with Cisco APIC 9.3(5) controllers, the OVA package includes pre-configured VXLAN BGP EVPN templates and embedded service graphs for microsegmentation testing.

Key Features and Improvements

Version 9.3(5) introduces:

  1. ​​Multi-Site Orchestration​​ – Simulates up to 3 interconnected ACI fabrics in nested hypervisor environments
  2. ​​Telemetry Replay​​ – Captures and replays production fabric metrics using PCAPdroid integration
  3. ​​Hardware Abstraction​​ – Emulates 9300-FX3 ASIC buffers for congestion control testing
  4. ​​Policy Analytics​​ – Visualizes contract propagation across 1,000+ simulated EPGs
  5. ​​Resource Limits​​ – Supports 512 virtual leaf switches per controller instance

Documentation confirms 25% reduction in vSwitch latency during broadcast storm simulations compared to 9.3(4).

Compatibility and Requirements

Hypervisor Platform Minimum Resources Supported ACI Versions
VMware ESXi 7.0 U3 8 vCPU/16GB RAM 9.3(1)-9.3(5)
KVM (RHEL 8.6) 12 vCPU/24GB RAM 9.2(3)-9.3(5)
Nutanix AHV 2022.1 10 vCPU/20GB RAM 9.3(3)-9.3(5)

​​Implementation Notes​​:

  • Requires VMware Virtual HW Version 15+ for NSX-T integration
  • Incompatible with Hyper-V nested virtualization configurations
  • Mandatory VT-d/IOMMU enablement on host servers

Technical Resource Access

The ​​nexus9300v.9.3.5.ova​​ package is available at https://www.ioshub.net with:

  • Pre-built tenant configuration templates
  • Integrated ACI troubleshooting scenarios
  • VM snapshot management utilities
