Introduction to C9800-CL-universalk9.17.06.06.ova
The C9800-CL-universalk9.17.06.06.ova file provides the Open Virtual Appliance (OVA) template for deploying Cisco Catalyst 9800-CL Cloud Wireless Controllers in virtualized environments. As part of the IOS XE 17.06.06 release (Q2 2025 maintenance update), this enterprise-grade solution enables centralized management of up to 6,000 access points across hybrid cloud infrastructures.
Designed for VMware ESXi and KVM hypervisors, this virtual appliance supports zero-touch provisioning of Catalyst 9100/9120AX access points while maintaining backward compatibility with AireOS 8.x migration templates. The release addresses critical vulnerabilities including CVE-2024-20389 through enhanced firmware signature validation.
