Introduction to nexus9300v64-lite.10.3.5.M.ova

The nexus9300v64-lite.10.3.5.M.ova is a lightweight virtual appliance image for network simulation and lab environments, supporting Cisco Nexus 9300v virtual switches in NX-OS 10.3(5)M. Optimized for VMware ESXi and Workstation deployments, this “Lite” version reduces resource consumption by 40% compared to full-featured OVA images while maintaining core NX-OS functionality.

Cisco released this version in Q4 2024 to facilitate SDN testing scenarios requiring multiple virtual switch instances. The -lite suffix indicates removal of redundant diagnostic tools and hardware-specific drivers.

Key Features and Improvements

1. ​​Resource Optimization​​

   • Reduces memory footprint to 8GB (vs 16GB in full OVA)
   • Supports concurrent operation of 5+ instances on 64GB host systems

2. ​​Feature Preservation​​

   • Maintains full VXLAN EVPN and BGP-LU protocol support
   • Includes Python API for Ansible/Terraform automation

3. ​​Security Enhancements​​

   • Implements SSHv2 with ECDSA-521 host key authentication
   • Removes deprecated TLS 1.0/1.1 cipher suites

4. ​​Management Upgrades​​

   • Supports NETCONF/YANG 1.1 with 50% faster configuration commits
   • Integrates with Cisco DNA Center 2.3.5 for policy templates

Compatibility and Requirements
