Introduction to BRKDCN-3678.pdf
BRKDCN-3678.pdf is Cisco’s official technical design guide detailing advanced implementation strategies for Nexus 9000 series switches operating in Application Centric Infrastructure (ACI) mode. This 2023 release focuses on fabric scalability enhancements and programmable data plane configurations for hyperscale data center deployments. The document provides validated reference architectures supporting multi-pod/multi-site ACI fabrics with VXLAN EVPN integration.
Compatible with Cisco Nexus 93180YC-FX/N9K-C9336C-FX2 platforms running NX-OS 14.2(x) or later, this guide addresses operational challenges in leaf-spine topologies exceeding 500 nodes. While specific release dates aren’t publicly disclosed, Cisco typically updates BRKDCN-series documentation quarterly alongside NX-OS feature releases.
Key Features and Improvements
This technical blueprint introduces:
- P4 Programmable Pipeline Optimization: Implementation guidelines for Barefoot Tofino-based Nexus 34180YC switches using P4_16 language extensions
- Zero-Touch Provisioning Workflows: Automated fabric bring-up procedures leveraging Cisco Network Services Orchestrator (NSO) 5.7+
- Telemetry Enhancements: OpenConfig/YANG model support for streaming interface statistics at 10-second intervals
- Security Posture Verification: Integration guidelines with Tetration Analytics for east-west traffic anomaly detection
Resolved design considerations include VXLAN BGP EVPN route reflector scalability limitations and multicast forwarding inefficiencies present in pre-14.2(x) NX-OS versions.
Compatibility and Requirements
| Component | Supported Versions | Notes |
|---|---|---|
| Cisco Nexus Switches | 9300/9500 Series (ACI Mode) | N9K-C9336C-FX2 confirmed |
| APIC Controllers | 5.3(1) – 6.0(3) | Multi-site orchestration requires APIC 5.3(2b)+ |
| VMware vSphere | 7.0 U3 – 8.0 | VDS 8.0 mandatory for VMM integration |
| Monitoring Tools | Tetration 3.7+, Splunk 8.2+ | Requires Cisco DCNM 12.0+ for full visibility |
Critical Limitations:
- P4 programmability unavailable on N9K-X9636C-R/X models
- Maximum 32-way ECMP in spine layers
- Service graph chaining requires ACI 5.3(2) with IS-IS redistribution enabled
