Introduction to nexus9300v64.10.2.4.M.qcow2 Software

This QCOW2 format virtual machine image provides an emulated Cisco Nexus 9300 Series switch environment running NX-OS Release 10.2(4)M. Designed for network simulation and pre-deployment testing, it replicates the hardware behaviors of physical Nexus 9300-FX/FX2 platform switches with 96% accuracy in control plane operations.

The 10.2(4)M release (Q4 2024) focuses on data center interconnection optimizations for virtualized environments. Supported hypervisor platforms include:

• VMware ESXi 7.0 U3+ with vSphere 7.0
• KVM/QEMU 6.2.0+ (RHEL 8.6/CentOS Stream 9)
• Microsoft Hyper-V 2022

Key Features and Improvements

This maintenance release introduces three core advancements:

1. ​​VXLAN Performance Optimization​​

   • 40% faster BGP-EVPN route convergence in multi-tenant configurations
   • Enhanced VXLAN flood suppression for multicast-heavy workloads
   • Improved VXLAN OAM packet handling (RFC 7348 compliance)

2. ​​Telemetry Enhancements​​

   • NetFlow v9 sampling rate increased to 1:1000 packets
   • Added gNMI telemetry support for interface counters
   • Reduced telemetry data export latency (<500ms)

3. ​​Security Updates​​

   • Patched 6 CVEs from Cisco PSIRT advisories (CSCwi44992, CSCwh33805)
   • TLS 1.3 support for REST API communications
   • MACsec key rotation interval reduced to 15 minutes

Compatibility and Requirements

​​Important Constraints​​

• Requires Intel VT-x/AMD-V virtualization extensions
• Incompatible with VMware Workstation Pro 17.x
• vSphere Distributed Switch (VDS) 7.0.3+ recommended
