Introduction to BRKARC-3863.pdf
This technical architecture document provides implementation blueprints for Cisco Catalyst 9200/9300/9400 series switches running IOS XE Amsterdam 17.9.1a. Designed for network architects, it details SD-Access underlay optimization strategies and TrustSec policy enforcement mechanisms compatible with Cisco DNA Center 2.3.5+.
The 89-page PDF contains validated design patterns for campus fabric deployments, including VXLAN EVPN multihoming configurations and Crosswork Network Controller integrations. Cisco’s internal testing confirms compatibility with Cisco UADP 3.0 ASIC-based line cards and StackWise Virtual topologies.
Key Features and Improvements
- Fabric Underlay Optimization
- Segment Routing IPv6 (SRv6) with 128-bit SID support
- BGP-LU (Labeled Unicast) for MPLS backbone convergence
- 25% faster EVPN route redistribution through enhanced RT constraints
- Security Enforcement
- MACsec 256GCM encryption for 100GbE interfaces
- SGT propagation across VXLAN overlay via CTS piggybacking
- Quantum-Resistant Cryptography trial configuration templates
- Telemetry Enhancements
- YANG-modeled EEM policies for streaming ASIC counters
- Cross-platform NetFlow v10 template sharing
- 40% reduction in gRPC dial-out latency through payload compression
