Introduction to nexus9500v64.10.4.1.F.qcow2 Software

This QCOW2-formatted virtual machine image delivers Cisco NX-OS 10.4(1)F for the Nexus 9500v virtual modular switch platform. Designed for large-scale network simulations and multi-tier cloud architecture validation, it replicates the functionality of physical Nexus 9500 chassis deployments in KVM/QEMU environments.

As part of Cisco’s virtualized switching portfolio, the 10.4(1)F release (Q3 2024) introduces enhanced VXLAN EVPN multi-site orchestration capabilities and improved TCAM resource allocation for spine-leaf topologies. The software requires Cisco Network Services Orchestrator (NSO) 6.2+ for full feature integration and supports up to 16 virtual line cards in modular configurations.

Key Features and Improvements

  1. ​​Security Enhancements​​
  • TLS 1.3 enforcement for NX-API and gRPC communications
  • Hardware-backed secure boot verification for virtual instances
  1. ​​Fabric Optimization​​
  • 40% faster BGP route convergence for topologies exceeding 1 million routes
  • VXLAN flood suppression via enhanced IGMPv3 snooping
  1. ​​Protocol Support​​
  • Segment Routing over IPv6 (SRv6) with 128-bit SID support
  • EVPN Type 5 route enhancements for hybrid cloud deployments
  1. ​​Critical Fixes​​
  • CVE-2024-20361 mitigation for control plane spoofing vulnerabilities
  • Resolved intermittent packet drops in VPC+ configurations with >64 member ports

Compatibility and Requirements

Supported Platforms Minimum Specifications
Cisco UCS C240 M6 KVM 6.2.0+
Red Hat Enterprise Linux 8.6 QEMU 6.2.0+
VMware ESXi 8.0 U2 16 vCPU / 64GB RAM
Ubuntu 22.04 LTS 250GB Storage

Known limitations include reduced throughput when nesting under Hyper-V 2022 clusters and temporary CLI latency during TCAM reallocations exceeding 80% utilization. Full interoperability requires Nexus 9300v virtual switches running 10.3(2)F or later.
