Introduction to pp-adv-c9800-1715.1-52-72.0.0.pack.zip Software
This device pack provides critical hardware abstraction layer updates for Cisco Catalyst 9800 Series Wireless Controllers running IOS XE 17.15.1 software. Released in Q1 2025, it enables enhanced AP firmware validation processes and introduces support for new 802.11ax (Wi-Fi 6E) access points including Catalyst 9168 and 9172 models. The package implements radio resource management (RRM) optimizations required for 160MHz channel operations in 6GHz spectrum, while maintaining backward compatibility with existing controller configurations.
