Introduction to C9800-CL-universalk9.17.15.02.ova Software

The C9800-CL-universalk9.17.15.02.ova is Cisco’s virtual appliance image for deploying the Catalyst 9800-CL Wireless Controller in cloud environments. This Open Virtualization Archive (OVA) package contains IOS XE Dublin-17.15.02 ED software optimized for VMware ESXi 7.0 U3+ and KVM hypervisors. Designed for hybrid cloud deployments, it enables centralized management of up to 6,000 Cisco Catalyst 9100/9120/9130/9160 series access points with enhanced IoT device orchestration capabilities.

Released in Q1 2025 as part of Cisco’s Extended Maintenance Release (EMR) cycle, this version introduces native Oracle Cloud Infrastructure (OCI) support and improved security compliance for federal networks. The virtual appliance format allows deployment across private cloud platforms (VMware, Hyper-V) and public cloud marketplaces like AWS and Azure.
