Introduction to C9800-CL-universalk9.17.02.01.ova Software
The C9800-CL-universalk9.17.02.01.ova represents Cisco’s cloud-optimized wireless controller software for virtualized deployments, supporting both private and public cloud infrastructures. Released under Cisco IOS XE Dublin-17.2.1 ED (Early Deployment) track, this Open Virtualization Archive (OVA) package enables seamless integration with major hypervisors while maintaining feature parity with physical Catalyst 9800 controllers.
Designed for enterprises requiring centralized wireless management across distributed locations, this version introduces enhanced scalability for up to 6,000 access points and 64,000 concurrent clients in cloud environments. The software maintains compatibility with Cisco’s intent-based networking architecture, offering programmable interfaces (NETCONF/YANG) and integration with Cisco DNA Center.
