Introduction to cat9k_lite_iosxe.17.06.02.SPA.bin Software

This lightweight software package provides Cisco IOS XE Bengaluru 17.6.2 functionality for Catalyst 9200L series switches, specifically designed for lean network deployments requiring optimized memory utilization. The “lite” designation indicates a streamlined image supporting essential Layer 2/Layer 3 operations while excluding resource-intensive services like SD-Access or advanced telemetry.

Compatible with Catalyst 9200L-24P-4G, 9200L-48T-4X, and 9200L-48PX-4X models manufactured after Q2 2024, this release focuses on operational stability for retail branch offices and small campus networks. Cisco officially published this maintenance update to address critical security vulnerabilities identified in previous 17.6.x releases.
