​​Introduction to C9800-CL-universalk9.17.06.01.tar.gz Software​​

The C9800-CL-universalk9.17.06.01.tar.gz package provides Cisco IOS XE 17.06.01 software optimized for Network Functions Virtualization Infrastructure (NFVIS) deployments on ENCS 5100/5400 series appliances. This specialized build enables cloud-managed wireless control for SD-WAN integrated networks, supporting up to 3,000 access points and 32,000 clients in hybrid cloud architectures.

Released in Q3 2021, this version delivers feature parity with physical Catalyst 9800 controllers while maintaining compatibility with Cisco DNA Center 2.1.2+ for policy orchestration. The TAR.GZ format contains pre-configured NFVIS templates and validation scripts for rapid deployment on Cisco Enterprise Network Compute Systems.
