Introduction to “guestshell.10.2.1.F.ova” Software

This Open Virtual Appliance (OVA) package delivers Cisco IOS XE Guest Shell 10.2.1.F – a secure Linux container environment for Catalyst 9000 series switches. Officially released in Q4 2024, it enables network engineers to deploy custom automation scripts and third-party applications within IOS XE’s sandboxed environment while maintaining full compatibility with Cisco’s Software-Defined Access (SD-Access) architecture.

The container image supports Catalyst 9300/9400/9500 platforms running IOS XE Fuji 16.12.x or later, providing Python 3.8 runtime, Docker API compatibility, and secure access to switch telemetry data through IOS XE’s RESTCONF interface.
