Introduction to pp-adv-cat9k-176.1a-43-64.0.0.pack
This Advanced Protocol Pack delivers critical industrial network protocol enhancements for Cisco Catalyst 9300/9400/9500X series switches running IOS XE 17.6.1a. Specifically engineered for manufacturing automation systems, version 64.0.0 introduces hardware-accelerated processing for EtherNet/IP Class 1 communications and improved TSN (Time-Sensitive Networking) capabilities.
Cisco officially released this package through its Industrial Network Advantage program on March 15, 2025, addressing compliance requirements for IEC 62443-4-1 certified environments. It supports concurrent operation of 14 industrial protocols with deterministic latency below 55μs for PROFINET IRT Class B applications.
