Introduction to C9800-L-hw-programmables.17.03.01.SPA.pkg
This specialized software package provides hardware-level programmability components for Cisco Catalyst 9800-L wireless controllers running IOS XE Cupertino 17.3.x releases. Officially released in Q2 2024 through Cisco’s security advisory CSCwh77482, it addresses FPGA firmware vulnerabilities in the QLogic 8300 series wireless modules while enabling OpenFlow 1.5 support for SDN integrations.
The package is mandatory for controllers managing Catalyst 9104/9115/9120 access points with 802.11ax Wave 3 hardware revisions. It maintains backward compatibility with Cisco DNA Center 2.3.5+ when using NETCONF/YANG 1.1 protocol extensions for programmable hardware management.
