Introduction to C9800-CL-universalk9.17.14.01.ova

This OVA template delivers Cisco IOS XE 17.14.01 for the Catalyst 9800-CL Cloud Wireless Controller – a virtualization-optimized WLC solution supporting hybrid cloud architectures. Released in Q3 2024 as part of the Dublin-17.14.x release train, it addresses critical security vulnerabilities while enhancing operational stability for enterprise wireless networks.

The OVA format streamlines deployment on VMware ESXi 7.0U3+ and integrates preconfigured resource profiles for medium-scale environments (2,000-4,000 APs). This build specifically resolves certificate validation errors in HA clusters and improves encrypted traffic analysis for IoT device management.
