Introduction to nexus9300v64.10.2.4.M.ova
This virtual appliance provides Cisco NX-OS Release 10.2(4)M for Nexus 9300v series virtual switches, enabling network engineers to simulate enterprise-grade data center topologies in VMware ESXi and KVM environments. Designed for network prototyping and ACI policy validation, it replicates the feature parity of physical Nexus 9300-EX hardware switches while supporting up to 64 virtual interfaces per instance.
The software package supports both NX-OS standalone mode and ACI fabric emulation, making it essential for pre-deployment testing of multi-protocol configurations. Released under Cisco’s Long-Lived Maintenance (LLM) cycle, it maintains backward compatibility with configurations from NX-OS 9.3(1)+ while introducing critical security updates.
Key Features and Improvements
1. Security Hardening
- Patches 8 CVEs from Cisco Security Advisory 2024-Q3 (CSCwd93542, CSCwh234X)
- Enforces TLS 1.3 for all management plane communications
- Enhanced RBAC with 32-tier permission granularity
2. Protocol Enhancements
- 25% faster VXLAN flood suppression compared to 10.2(3)M
- Improved BGP EVPN route convergence time (1.8s → 1.2s)
- Extended MACsec support for virtual 25GbE interfaces
3. Operational Efficiency
- RESTCONF API response latency reduced by 30%
- Real-time telemetry sampling adjustable from 15s to 10m intervals
- Cross-fabric EPG visualization in topology mapping
4. Virtualization Optimization
- Memory footprint reduced by 18% vs 10.1(2)M
- Support for VMware ESXi 8.0 U2+ and KVM QEMU 7.0+
- Hot-swappable virtual line card emulation
Compatibility and Requirements
| Virtualization Platform | CPU Allocation | Memory Requirement | Storage |
|---|---|---|---|
| VMware ESXi 7.0 U3+ | 4 vCPUs | 16GB DRAM | 50GB |
| KVM (QEMU 7.0+) | 6 vCPUs | 24GB DRAM | 65GB |
| Nutanix AHV 2022.1+ | 8 vCPUs | 32GB DRAM | 75GB |
Critical Constraints
- Requires existing NX-OS 9.3(1)+ for in-service upgrades
- Incompatible with VMware Distributed Switch 7.x configurations
- vMotion operations require 10Gbps vSAN connectivity
