Introduction to c8000aep-universalk9_noli.17.06.06a.SPA.bin
This Cisco IOS XE software package provides critical maintenance updates and feature enhancements for Catalyst 8000 Series routers, specifically designed for enterprise edge and SD-WAN deployments. The “_noli” designation indicates this build excludes certain telemetry components for environments with strict data sovereignty requirements. Released as part of the Fuji 17.06.x train, version 17.06.06a addresses 18 CVEs while maintaining backward compatibility with legacy WAN interfaces.
Compatible with C8500/C8300/C8200 platforms, this release focuses on operational stability for networks transitioning to Secure Access Service Edge (SASE) architectures. The software supports FIPS 140-2 Level 1 cryptographic validation, making it suitable for government and financial sector deployments.
