Introduction to guestshell.10.2.1.F.ova
This OVA template provides a preconfigured Linux-based container environment for Cisco Catalyst 9300/9400/9500 series switches running IOS XE Fuji 17.3.x releases. Designed to enable secure host-side scripting and automation workflows, it implements Cisco’s Guest Shell 3.0 architecture with enhanced resource isolation from the underlying network OS.
Compatible with WS-C9300-48UXM and WS-C9500-40X hardware platforms, this container environment supports Python 3.11 runtime, Ansible modules, and REST API toolkits for network automation. Cisco officially released this version on March 15, 2025, as part of their DevOps Enablement Package for enterprise networks.
