Introduction to guestshell_4.0.10.4.2.F.ova

This OVA package provides Cisco’s Guest Shell 4.0 container environment for Catalyst 9200/9300/9400/9500 series switches running IOS XE Fuji 17.9.x and later. Officially released in Q4 2024, it delivers enhanced security protocols and optimized resource allocation for network automation workflows.

The container supports Python 3.11 runtime with pre-integrated NETCONF/YANG libraries, enabling secure API-driven configuration management while maintaining complete isolation from the host IOS XE operating system.
