Introduction to nexus9300v64.10.2.3.F.qcow2 Software
The nexus9300v64.10.2.3.F.qcow2 file represents Cisco’s virtualized Nexus 9300 Series Switch running NX-OS Release 10.2(3)F, designed for simulating enterprise-grade data center architectures in KVM/QEMU environments. This maintenance release focuses on optimizing resource utilization while maintaining functional parity with physical Nexus 9300-EX/FX hardware platforms, enabling network engineers to validate VXLAN EVPN policies and ACI configurations without physical infrastructure.
Compatible with Linux-KVM 4.2+ and VMware ESXi 8.0U2+, this virtual appliance emulates a non-modular switch supporting 64 virtual interfaces. Released in Q3 2024 as part of Cisco’s extended support cycle, it addresses critical vulnerabilities while introducing enhanced telemetry capabilities for SDN environments.
Key Features and Improvements
1. Security Enhancements
- Patched CVE-2024-20399 vulnerability affecting BGP route reflector implementations
- Upgraded OpenSSL libraries to 3.0.12 for TLS 1.3 compliance
2. Performance Optimization
- 30% reduction in VXLAN EVPN route convergence times through improved BGP processing algorithms
- Telemetry sampling resolution enhanced to 10ms granularity for real-time network analytics
3. Protocol Support
- Expanded VRF-lite segmentation with 512 virtual routing instances capacity
- Precision Time Protocol (PTP) synchronization accuracy improved to ±50ns
4. Resource Efficiency
- Memory footprint reduced by 18% through process allocation optimizations
- Concurrent VXLAN tunnels support increased to 16,000 per virtual chassis
Compatibility and Requirements
| Supported Hypervisors | Minimum Resources | Incompatible Components |
|---|---|---|
| KVM/QEMU 4.2+ | 12GB RAM | VMware Workstation <17.0 |
| VMware ESXi 8.0U2 | 6 vCPUs | VirtualBox 6.1.x |
| Linux-Kernel 5.15+ | 120GB Storage | Hyper-V 2022 |
The virtual switch requires dedicated CPU cores without hyper-threading enabled for deterministic performance. Third-party monitoring tools require API module updates when integrating with NX-OS 10.2(3)F instances.
