Introduction to c8000aes-universalk9_noli.17.12.03.SPA.bin

Designed for Cisco Catalyst 8300/8500 Series Edge Platforms, this firmware delivers IOS XE Amsterdam 17.12.03 with enhanced Zero Trust networking capabilities. The “_noli” designation indicates a non-licensed base image optimized for secure SD-WAN edge deployments requiring FIPS 140-3 validated cryptography. Cisco released this version in Q1 2025 to address CVE-2024-20356 (BGP session hijacking) and CVE-2024-21234 (IPsec key negotiation vulnerabilities) identified in previous releases.

The software supports hybrid cloud architectures with pre-integrated Azure Virtual WAN and AWS Cloud WAN templates. It maintains backward compatibility with existing 17.12.x configurations while introducing new telemetry features for Cisco ThousandEyes integration.
