Introduction to “cat9k_iosxe.17.03.01.SPA.bin” Software
This consolidated software package delivers Cisco IOS XE Amsterdam 17.3.1 for Catalyst 9300 Series Switches, addressing critical network infrastructure requirements for enterprise access layer deployments. Released in Q1 2023 as part of the Amsterdam 17.3.x software train, it provides security hardening and feature parity with Cisco’s SD-Access architecture implementations.
The firmware supports all Catalyst 9300 models (C9300-24UB, 48UN, 48UXM, etc.), including both fixed and modular variants. As a Single Package Archive (SPA), it combines essential components for wireless controller integration, DNA Center compatibility, and advanced QoS capabilities in a unified binary.
