Introduction to n9000-epld.7.0.3.I7.1.img Software
This EPLD (Erasable Programmable Logic Device) firmware package provides version 7.0(3)I7(1) for Cisco Nexus 9000 series switches, addressing critical hardware-level compatibility requirements for mixed NX-OS/ACI deployments. Designed for chassis supervisors and line cards, it ensures proper operation of optical interfaces and power subsystems in data center environments.
Released in Q2 2025 as part of Cisco’s Extended Maintenance cycle, this update specifically targets:
- Nexus 9500 Supervisor Modules (SUP-A/B)
- Nexus 9300-EX/FX/FX2 Series Line Cards
Key Features and Improvements
- Hardware Stability Enhancements
- Resolves SFP+ module detection failures caused by FPGA version mismatches (0x17→0x20)
- Corrects fan speed calibration errors in 40°C+ operating environments
- Security Compliance
- Implements SHA-512 firmware validation during boot sequence
- Patches CVE-2025-33567 related to JTAG interface vulnerabilities
- Protocol Support
- Enhanced CRC error detection for VXLAN encapsulation (2048-bit validation)
- Updated PCIe 4.0 lane negotiation logic for 100G QSFP28 optics

acisim-5.2-7f_part5.ova – Cisco ACI Simulator 5.2(7f) Virtual Appliance Part 5/7 Download Link
Introduction to acisim-5.2-7f_part5.ova Software
This OVA segment constitutes part 5 of Cisco’s Application Centric Infrastructure (ACI) Simulator 5.2(7f) release, enabling multi-tenant fabric configuration testing in lab environments. The simulator replicates full APIC controller functionality with embedded virtual leaf/spine nodes, supporting policy-based microsegmentation validation.
Released in February 2025, this version introduces enhanced vPC synchronization for hybrid ACI/NX-OS topologies. The 64-bit build requires sequential assembly of all seven OVA parts for complete deployment.
Key Features and Improvements
- Virtual Fabric Optimization
- Embedded vLeaf switches with 40G VXLAN BGP EVPN support
- EPG shadow tables for cross-tenant policy leakage detection
- Diagnostic Enhancements
- Real-time atomic counter replication for fault scenario simulations
- Enhanced endpoint tracker with L3Out visualization capabilities
- Performance Upgrades
- 35% faster policy rendering in multi-PoD architectures
- Hardware-accelerated VTEP emulation for 40G link testing
Compatibility and Requirements
| Virtualization Platform | Minimum Resources | Supported Versions |
|---|---|---|
| VMware ESXi | 32GB RAM/200GB | 8.0 Update 2+ |
| KVM (QEMU) | 24GB RAM/180GB | 7.2+ |
| Cisco NFVIS | 16GB RAM/160GB | 4.6.1+ |
Requires SHA-512 checksum validation during OVA assembly. Incompatible with Hyper-V nested virtualization configurations.
