Introduction to c8000aep-universalk9.17.15.01a.SPA.bin Software

This Cisco IOS XE 17.15.1a release delivers enterprise-grade routing capabilities for Catalyst 8200/8300 series edge platforms, optimized for hybrid cloud and 5G edge computing deployments. Officially released in Q4 2024 as part of Cisco’s Extended Maintenance Release (EMR) cycle, it provides 24-month defect resolution support with enhanced SD-WAN integration for distributed network architectures.

The software specifically targets Catalyst 8000v and physical 8200-32FH/8300-48NMP models, offering non-disruptive upgrades for environments requiring continuous uptime. Its modular architecture enables simultaneous operation of traditional routing and SD-WAN services, making it ideal for multi-cloud application delivery scenarios.
