Introduction to pp-adv-cat8k-179.1a-46-65.0.0.pack

This software package delivers advanced SD-WAN capabilities for Cisco Catalyst 8000 Series routers, extending their application-aware routing and cloud security functionalities. Designed for enterprises managing hybrid cloud infrastructures, it integrates with Cisco IOS XE Amsterdam 17.9.x releases to enable zero-trust network access and 5G-ready edge deployments. The bundle specifically addresses CSCwh87343 – a critical vulnerability in application recognition engines affecting policy enforcement accuracy.

Compatible with physical and virtual Catalyst 8000 platforms (C8000V/8200/8300/8500), this Q2 2025 release introduces dynamic SaaS optimization for Microsoft 365 and Zoom workloads. The package maintains backward compatibility with IOS XE 17.6.1a deployments through modular dependency resolution.
