Introduction to pp-adv-c9800-1712.1-49-72.0.0.pack.zip Software
This device pack provides hardware abstraction layer updates for Cisco Catalyst 9800 Series Wireless Controllers running IOS XE 17.12.1 software. Released in Q2 2025, it enables support for new 802.11be (Wi-Fi 7) access points including Catalyst 9168 and 9172 models, while maintaining backward compatibility with existing WLC configurations.
The package implements critical radio resource management (RRM) optimizations required for 320MHz channel bandwidth operations in 6GHz spectrum. Network administrators must install this update before deploying Wi-Fi 7 access points in environments using C9800-80/C9800-CL controllers with 32GB+ RAM configurations.
