Introduction to oac.7.3.3.N1.1.ova Software
This Open Virtual Appliance (OVA) package provides the Cisco Network Automation Controller virtual instance, designed for orchestrating multi-vendor network infrastructures through RESTCONF/YANG APIs. Released in Q1 2025 as part of Cisco’s SDN 3.0 initiative, version 7.3.3.N1.1 introduces enhanced template validation engines and Kubernetes cluster integration for containerized network functions (CNFs).
The virtual appliance supports hybrid cloud deployments with native integration for AWS Outposts and Azure Stack Edge, enabling consistent policy enforcement across physical and virtual network domains.

Introduction to n5000_poap_script.7.3.3.N1.1.tcl Software
This TCL script implements enhanced Power-On Auto Provisioning (POAP) workflows for Cisco Nexus 5010/5548UP switches, optimized for high-availability storage area network (SAN) deployments. Version 7.3.3.N1.1 (Q2 2025) introduces dynamic VSAN zoning validation and FCoE buffer pre-allocation algorithms.
The script supports automated firmware validation against Cisco’s Cryptographic Assurance Program (CAP) hashes while maintaining compatibility with legacy Fibre Channel fabrics.
Key Features and Improvements
Deployment Automation
- 50% faster DHCP negotiation through optimized Option 67 parsing
- Automatic DCBx 2.0 parameter negotiation
- Dual-stack IPv4/IPv6 configuration template support
Fabric Management
- VSAN membership conflict detection during initialization
- Dynamic buffer allocation for lossless Ethernet flows
- Automated UDLD aggressive mode activation
Security Protocols
- HMAC-SHA384 signature verification for golden configurations
- TLS 1.3 encrypted template transfers
- RBAC enforcement through TACACS+ attribute filtering
Compatibility and Requirements
| Supported Hardware | NX-OS Version | TCL Runtime |
|---|---|---|
| Nexus 5010 | 7.3(1)N1(1) | 8.5+ |
| Nexus 5548UP | 7.3(3)N1(1) | 8.6+ |
| Nexus 5020 | 7.3(5)N1(1) | 8.7+ |
Critical Compatibility Notes
- Requires DHCP servers supporting RFC 5071 Cookie option
- Incompatible with FEX 2200 series fabric extenders
- Minimum 8MB free bootflash for temporary storage
