Introduction to c8000aes-universalk9_noli.17.16.01a.SPA.bin Software

Designed for Cisco Catalyst 8000 Series edge platforms, the ​​c8000aes-universalk9_noli.17.16.01a.SPA.bin​​ software package delivers enhanced routing, security, and SD-WAN capabilities under Cisco IOS XE Amsterdam 17.16.x. This ​​No License Integrity (NLI)​​ variant excludes export-controlled cryptographic features for compliance with regional regulations.

As the successor to 17.15.x releases, this version focuses on enterprise edge deployments requiring high-performance VPN termination and zero-trust network segmentation. The software supports Catalyst 8200/8300/8500 routers, enabling hybrid workforce connectivity with cloud-optimized application delivery. Cisco officially released this build in Q2 2025 as part of its quarterly software maintenance cycle.
