Introduction to C9800-SW-iosxe-wlc.17.07.01.SPA.bin

This software package provides Cisco IOS XE Cupertino 17.7.1 for Catalyst 9800 Series Wireless LAN Controllers (WLCs), delivering enterprise-grade wireless management for Wi-Fi 6E and 5G-ready networks. Designed for high-density deployments in healthcare, education, and industrial IoT environments, it integrates with Cisco DNA Center for centralized policy enforcement and AI-driven analytics.

Released in Q4 2024 (as per Cisco’s internal build timestamps), this version addresses critical vulnerabilities reported in earlier 17.7.x releases while maintaining backward compatibility with Catalyst 9100/9120/9130/9160 series access points. The SPA (Software Package Archive) format ensures atomic updates for 9800-40, 9800-80, 9800-L, and C9800-CL virtual controller platforms.
