Introduction to C9800-CL-universalk9.17.09.07.qcow2 Software

The C9800-CL-universalk9.17.09.07.qcow2 file represents Cisco’s KVM-optimized cloud wireless controller image, part of the IOS XE Dublin 17.9.x software branch. Designed for Linux Kernel-based Virtual Machine (KVM) environments, this QCOW2 format virtual disk enables enterprise-grade wireless network management in private cloud deployments.

As a production-ready release validated for Red Hat Enterprise Linux 7.6+ and Ubuntu 16.04 LTS platforms, this version supports centralized control of up to 6,000 access points with native integration to Cisco DNA Center 2.3.5+ management systems. The software package received Cisco’s cryptographic validation on July 31, 2023, meeting FIPS 140-2 Level 1 compliance requirements.
