Introduction to cat9k_lite_iosxe.17.03.05.SPA.bin

This maintenance release for Cisco Catalyst 9300 Series Switches delivers IOS XE 17.3.5, focusing on operational stability and security compliance for mid-sized enterprise networks. As part of the Amsterdam release train, it addresses 23 documented defects while maintaining backward compatibility with existing SD-Access deployments.

The firmware supports Catalyst 9300L and 9300SK hardware variants, optimized for environments requiring reduced power consumption and simplified license management. Cisco recommends this build for organizations transitioning from legacy IOS to intent-based networking architectures.
