Introduction to CW9800H-wlc-universalk9.17.17.01.SPA.bin
This firmware package delivers Cisco IOS XE 17.17.01 for Catalyst 9800H series wireless controllers, designed to address enterprise-grade wireless network management requirements with enhanced multi-cloud capabilities. Released in May 2025, it introduces critical security patches for CAPWAP tunnel vulnerabilities while optimizing controller performance in high-density deployments supporting up to 10,000 access points.
The software enhances interoperability with Catalyst 9100/9136AX Wi-Fi 7 access points and industrial IoT devices like IW9167E rugged APs. It integrates with Cisco DNA Center 2.3.7 for centralized policy enforcement across hybrid cloud environments, including AWS Outposts and Microsoft Azure Stack deployments.
