Introduction to c8000aep-universalk9_noli.17.09.05a.SPA.bin

This Cisco IOS XE software package provides critical security updates and operational enhancements for Catalyst 8000 Series routers deployed in SD-WAN and enterprise edge environments. The “_noli” designation indicates this build excludes telemetry components for networks requiring strict data governance compliance. Released as part of the Bengaluru 17.09.x train, version 17.09.05a resolves 18 CVEs while introducing performance optimizations validated through Cisco TAC engineering teams.

Compatible with C8500/C8300/C8200 platforms, this release focuses on network stability for hybrid cloud architectures. It implements NIST SP 800-203 compliance for cryptographic operations, making it suitable for government deployments requiring FIPS 140-3 Level 1 validation.
