Introduction to c8000aes-universalk9.17.15.01a.SPA.bin
This enterprise-grade software package delivers Cisco IOS XE Amsterdam 17.15.1a for Catalyst 8200/8300 Series Edge Platforms, specifically optimized for SD-WAN deployments requiring enhanced NAT management and IPv6 segmentation routing. Released in September 2024, it targets organizations operating hybrid cloud infrastructures with 400G interface requirements while maintaining backward compatibility with legacy 100G deployments.
Designed for C8200-1N-4S and C8300-2N2S-4T hardware configurations, this build introduces quantum-resistant encryption modules and improved telemetry capabilities. Cisco officially recommends deployment for environments requiring concurrent management of >5,000 IPSec tunnels with FIPS 140-3 validated cryptographic operations.
