Introduction to nexus9500v64.10.2.3.F.ova
This virtual appliance delivers Cisco NX-OS Release 10.2(3)F for the Nexus 9500v modular switch platform, designed for simulating large-scale data center topologies in VMware ESXi and KVM environments. As part of Cisco’s virtual switching portfolio, it enables network engineers to validate multi-tier architectures with up to 16 virtual line cards and 400 interfaces per instance.
The software maintains functional parity with physical Nexus 9500 chassis systems, supporting policy-based automation and SDN prototyping. Released under Cisco’s Extended Maintenance cycle, it provides backward compatibility with configurations from NX-OS 9.3(1)+ while introducing critical security updates.
Key Features and Improvements
1. Architectural Enhancements
- Supports 64 virtual interfaces per line card with dynamic resource allocation
- Modular chassis emulation with hot-swappable virtual line cards
- Cross-fabric EPG visualization for ACI policy validation
2. Security Updates
- Addresses 9 CVEs from Cisco Security Advisory 2024-Q4
- Implements TLS 1.3 enforcement for management plane
- Enhanced RBAC with 32-tier permission granularity
3. Protocol Optimization
- 35% faster VXLAN flood suppression vs 10.1(2)F
- BGP EVPN convergence time reduced to 1.5s
- Improved MACsec support for virtual 100G interfaces
4. Operational Tools
- RESTCONF API latency reduced by 40%
- Adjustable telemetry sampling from 15s to 10m intervals
- CLI-based health monitoring without GUI dependencies
Compatibility and Requirements
| Virtualization Platform | Minimum Resources | Supported Host Hardware |
|---|---|---|
| VMware ESXi 8.0 U2+ | 24GB RAM / 4 vCPU | Cisco UCS C480 M5 |
| KVM (QEMU 7.2+) | 32GB RAM / 6 vCPU | HPE ProLiant DL380 Gen10+ |
