Introduction to pp-adv-c9800-176.1a-43-64.0.0.pack

This advanced protocol pack enhances Layer 3-7 service capabilities for Cisco Catalyst 9800 Wireless Controllers running IOS® XE Amsterdam 17.6.x. Designed for enterprise networks requiring granular traffic analysis, it integrates with Cisco DNA Center 2.3.5’s application visibility toolkit while maintaining full backward compatibility with existing policy configurations.

The software supports physical controllers (C9800-40/80) and cloud-managed C9800-CL instances deployed in SD-Access fabrics. Primary applications include healthcare IoT device management, financial transaction monitoring, and industrial control system (ICS) protocol optimization. The package requires base controller software version 17.6.1a for installation.
