Introduction to C9800-CL-universalk9.17.03.04c.qcow2

This QCOW2 format virtual appliance provides optimized deployment templates for Cisco Catalyst 9800-CL controllers in cloud-native environments. Released under Cisco’s Q2 2025 maintenance cycle, it implements storage I/O enhancements that reduce boot time by 25% compared to previous iterations (v17.03.02a) while maintaining backward compatibility with existing Wi-Fi 7 network profiles.

The image supports automated scaling in Kubernetes clusters through integration with Cisco Cloud Controller Manager 3.2.1 and includes pre-configured Smart Licensing Using Policy (SLUP) templates for air-gapped network environments. Compatible with OpenStack Zed (2023.1), VMware vSphere 8.0U3, and KVM virtualization platforms.
