Introduction to “nexus9500v64.10.2.4.M.ova” Software

The “nexus9500v64.10.2.4.M.ova” file contains Cisco’s Nexus 9500v Virtual Switch software running NX-OS 10.2(4)M, designed for simulating modular data center switching architectures in lab environments. This OVA package emulates the physical Nexus 9500 platform’s functionality, supporting up to 16 virtual line cards and 400 interfaces on VMware ESXi 8.0U2+ and KVM/QEMU 5.2+ hypervisors. Released in Q2 2023, this version provides network engineers with a sandbox environment to validate spine-leaf topologies, test multi-protocol configurations, and develop automation scripts without requiring physical Nexus 9000 Series hardware.

Key Features and Improvements

1. Enhanced Virtualization Performance

• 40% reduction in memory footprint compared to NX-OS 9.x versions
• Support for 64-bit nested virtualization on Intel VT-x/AMD-V enabled hosts

2. Security Upgrades

• TLS 1.3 enforcement for all management plane communications
• Automated certificate rotation via REST API for virtual fabric components

3. Protocol Enhancements

• VXLAN EVPN control plane optimizations with 25% faster convergence
• BGP Add-Path support for improved multi-homed route selection

4. Operational Tools

• Real-time TCAM utilization monitoring through CLI/API
• Pre-configured QoS templates for voice/video/data traffic classes

Compatibility and Requirements

​​Critical Compatibility Notes​​:

• Incompatible with Hyper-V and XenServer platforms
• Requires VMware Hardware Version 19+ for full feature support
• Virtual interfaces don’t support hardware-accelerated encryption
