Introduction to nexus9300v64-lite.10.4.3.F.ova

This OVA package provides the virtualized implementation of Cisco Nexus 9300v switches running NX-OS Release 10.4(3)F, designed for data center network simulation and lab environments. As a lightweight version of the physical Nexus 9300 Series hardware, it enables full-featured Layer 2/Layer 3 switching capabilities in virtualized infrastructure like VMware ESXi or KVM hypervisors.

The software supports advanced features including VXLAN bridging, EVPN routing, and integration with Cisco Application Centric Infrastructure (ACI). Version 10.4(3)F introduces critical security patches and protocol optimizations validated through Cisco’s technical validation cycles.

Key Technical Enhancements

​​1. Security Hardening​​

  • Resolved 12 CVEs related to BGP and OSPF protocol stacks
  • Implemented TACACS+ command authorization improvements for RBAC policies

​​2. VXLAN Performance Optimization​​

  • Increased multicast traffic handling capacity by 40% in bridge-domain configurations
  • Enhanced VTEP scalability supporting up to 512 virtual tunnel endpoints

​​3. EVPN Enhancements​​

  • Added Type-5 route support for L3VPN integration
  • Reduced ARP/ND synchronization latency in multi-pod ACI fabrics

​​4. Resource Efficiency​​

  • 18% reduction in vCPU utilization during sustained 10Gbps traffic loads
  • Memory footprint optimized to 8GB minimum allocation for lab deployments

Supported Virtualization Platforms

Hypervisor Minimum Version Recommended Resources
VMware ESXi 7.0 U3 4 vCPU, 16GB RAM
KVM (RHEL) 8.6 6 vCPU, 24GB RAM
Microsoft Hyper-V 2019 8 vCPU, 32GB RAM

Compatibility data sourced from Cisco Virtual Switching System documentation

Known Compatibility Considerations

  • Requires VMware Tools version 12.1.5+ for VMXNET3 adapter stability
  • Incompatible with NSX-T 4.1 distributed firewall policies
  • Limited to 40Gbps aggregate throughput in nested virtualization configurations

For production-grade performance, Cisco recommends physical Nexus 9300 Series switches with dedicated ASICs.
