Introduction to nxos.9.3.2.bin Software
This NX-OS system image delivers critical infrastructure enhancements for Nexus 3232C/3264Q/3548-XL switches, specifically addressing multicast forwarding inconsistencies reported in CSCvt02249. Validated with Cisco’s Extended Maintenance lifecycle, the 9.3(2) release introduces VXLAN EVPN multi-site orchestration capabilities for hybrid cloud deployments.
Compatible with Nexus 3000 Series hardware running 7.0(3)I7(8) or later, it supports automated fabric provisioning through Cisco DCNM 12.0.1+. The software passed FIPS 140-2 Level 1 validation on February 28, 2024, making it suitable for government and financial sector deployments.
Key Features and Improvements
-
VXLAN EVPN Enhancements
Supports 16,000 virtual networks per VDC with BGP route reflector scaling optimizations. -
CoPP Security Hardening
Implements role-based ACL enforcement for control-plane protection (CoPP) policies, resolving privilege escalation risks in previous releases. -
Telemetry Optimization
Delivers 1-second granularity for queue depth monitoring through OpenTelemetry 1.2 integration. -
FHRP Stability
Reduces First Hop Redundancy Protocol convergence time to <200ms in vPC topologies.

Introduction to aci-n9000-dk9.16.1.1f-cs_64.bin Software
This Application Centric Infrastructure (ACI) system image enables intent-based networking for Nexus 93180YC-FX3 spine switches in multi-pod architectures. Certified with APIC 5.2(7d)+ controllers, it resolves endpoint learning latency issues in stretched fabric deployments.
The “16.1.1f” build introduces quantum-resistant encryption for VXLAN data planes using CRYSTALS-Kyber algorithms, meeting NIST SP 800-208 compliance requirements. Validated for 400G-ZR coherent optics calibration on July 15, 2024.
Key Features and Improvements
-
Multi-Site Orchestration
Supports 8-site fabric topologies with sub-50ms failure recovery. -
Telemetry Integration
Streamlines 150+ metrics to Splunk via Apache Kafka 3.5 pipelines. -
Security Enhancements
Implements MACsec 256-bit encryption with 25% reduced latency overhead. -
Container Networking
Integrates with Red Hat OpenShift 4.12 through CNI plug-in auto-configuration.
Compatibility and Requirements
| Supported Hardware | APIC Minimum | Memory |
|---|---|---|
| Nexus 93180YC-FX3 | 5.2(7d) | 128GB |
| Nexus 9336C-FX2 | 6.0(1a) | 256GB |
| Nexus 93600CD-GX | 6.1(2g) | 512GB |
Dependencies:
