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

  1. ​​VXLAN EVPN Enhancements​​
    Supports 16,000 virtual networks per VDC with BGP route reflector scaling optimizations.

  2. ​​CoPP Security Hardening​​
    Implements role-based ACL enforcement for control-plane protection (CoPP) policies, resolving privilege escalation risks in previous releases.

  3. ​​Telemetry Optimization​​
    Delivers 1-second granularity for queue depth monitoring through OpenTelemetry 1.2 integration.

  4. ​​FHRP Stability​​
    Reduces First Hop Redundancy Protocol convergence time to <200ms in vPC topologies.

Compatibility and Requirements

Supported Hardware Minimum NX-OS Memory
Nexus 3232C 7.0(3)I7(8) 16GB
Nexus 3264Q 9.2(1) 32GB
Nexus 3548-XL 9.2(4) 64GB

​​Critical Notes​​:

  • Requires BIOS version 3.2.7 on Nexus 3548-XL chassis
  • Incompatible with 400G-FR4 optics on 3232C platforms

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

  1. ​​Multi-Site Orchestration​​
    Supports 8-site fabric topologies with sub-50ms failure recovery.

  2. ​​Telemetry Integration​​
    Streamlines 150+ metrics to Splunk via Apache Kafka 3.5 pipelines.

  3. ​​Security Enhancements​​
    Implements MACsec 256-bit encryption with 25% reduced latency overhead.

  4. ​​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​​:

  • Requires matching APIC-CCO image 16.1(1f)-cs-co
  • Incompatible with N9K-X9736C-FX linecards
