Introduction to C9800-CL-universalk9.17.17.01.tar Software
The C9800-CL-universalk9.17.17.01.tar is Cisco’s compressed software archive for deploying the Catalyst 9800-CL Wireless Controller in cloud environments running IOS XE Dublin-17.17.01 ED. This release focuses on enhanced security compliance and industrial IoT device management, supporting deployments across VMware ESXi 8.0 U3+, KVM (RHEL 9.6+), and Cisco ENCS platforms.
Designed for hybrid cloud architectures, this version introduces automated certificate lifecycle management for 10,000+ access points while maintaining backward compatibility with Catalyst 9100/9120/9130/9160 series APs. Cisco officially released this LTS (Long-Term Support) version in Q1 2025 to address critical infrastructure network requirements.
