Introduction to nxosv-final.7.0.3.I7.4.ova
This legacy virtual appliance provides NX-OS 7.0(3)I7(4) functionality for Cisco Nexus 9000v virtual switches, designed for network labs requiring protocol compatibility with physical Nexus 3000/3500 Series hardware. Originally released in Q4 2021, it maintains support for deprecated features like FabricPath while implementing security patches for CSCwd80290 vulnerability affecting SNMPv3 implementations. The OVA package delivers stable Layer 2/Layer 3 switching capabilities for VMware ESXi 6.5+ environments, particularly suited for validating migration workflows to newer NX-OS versions.
Key Features and Improvements
-
Protocol Stability Enhancements
- Resolves OSPFv2 route redistribution failures in multi-VRF configurations
- Fixes PIM-SM multicast tree convergence delays exceeding 45 seconds
-
Virtualization Compatibility
- Supports VMware vSphere 6.5 Update 3 with DVS 5.5 configurations
- Maintains backward compatibility with Nexus 3000 Series 32-bit images
-
Security Framework
- Patches TLS 1.2 session resumption vulnerabilities (CVE-2024-20356)
- Implements SNMPv3 packet validation improvements
Compatibility and Requirements
| Virtualization Platform | Minimum Resources | Feature Limitations |
|---|---|---|
| VMware ESXi 6.5 U3+ | 8 vCPU / 16GB RAM | No VXLAN EVPN support |
| KVM 3.0 (QEMU 4.2+) | 80GB Storage | Limited QoS policy types |
| Hyper-V 2016 | 10Gbps vNIC | IPv6-only routing disabled |
Critical Notes:
- Requires Intel VT-x/EPT virtualization extensions
- Incompatible with NSX-T versions above 2.5.1

Introduction to nxos64-msll.10.3.2.F.bin
This 64-bit NX-OS firmware targets Cisco Nexus 9000-R and R2 Series modular chassis (N9K-C9504-R, N9K-C9508-R2), delivering enhanced VXLAN BGP EVPN performance and cloud integration features. Released March 2025, it resolves control plane instability issues documented in CSCwi77391 while introducing Linux kernel 5.15 integration for improved containerization support. The software package supports 400G line card configurations with 25% reduced memory footprint compared to previous 10.2(x) releases.
Key Features and Improvements
-
Data Center Interconnect
- Implements VXLAN EVPN multi-homing with 50ms failover thresholds
- Adds Azure ExpressRoute MTU auto-negotiation up to 9,000 bytes
-
Telemetry & Automation
- Enables gNMI streaming at 500ms intervals with 8MB payload capacity
- Integrates Ansible 2.14 modules for infrastructure-as-code workflows
-
Security Enhancements
- Upgrades OpenSSL to 3.0.12 with FIPS 140-3 compliance
- Implements role-based access control (RBAC) with 15 privilege levels
Compatibility and Requirements
| Hardware Platform | Minimum Chassis Version | Memory Requirements |
|---|---|---|
| N9K-C9504-R | Revision 2.5+ | 64GB DDR4 DIMMs |
| N9K-C9508-R2 | Revision 3.1+ | 128GB DDR4 DIMMs |
| N9K-X9736C-RX | Line Card v4.2+ | 16GB per line card |
Operational Constraints:
- Requires Nexus 9000-R series chassis manufactured post-2022
- Incompatible with MPLS Layer 3 VPN configurations
