Introduction to guestshell.10.2.3.F.ova Software

The ​​guestshell.10.2.3.F.ova​​ is a preconfigured virtual machine template enabling secure containerized application deployment on Cisco Catalyst 9000 series switches running IOS XE Fuji 10.2(3)F. This Open Virtual Appliance (OVA) package provides a Linux-based sandbox environment for running third-party Python scripts, monitoring tools, and custom automation workflows while maintaining strict separation from the host network OS.

Officially released in Q1 2025, this version introduces enhanced resource isolation controls and expanded API integration for Cisco DNA Center 2.3.7+ environments. It supports zero-touch provisioning in SD-Access architectures and complies with FIPS 140-3 cryptographic standards for government deployments.
