Introduction to guestshell_4.0.10.4.2.F.ova Software
The guestshell_4.0.10.4.2.F.ova represents Cisco’s containerized Linux environment for IOS XE network devices, providing a secure sandbox for running Python scripts, third-party applications, and network automation tools. This Q3 2024 release enhances operational flexibility for Catalyst 9000 series switches and ISR routers, enabling DevOps-style workflows without compromising device stability.
Compatible with IOS XE 17.12.1+ versions, this OVA package implements kernel-level isolation through Linux Containers (LXC), maintaining separate memory allocation and process space from the host OS. The “.F” designation indicates feature release status with full backward compatibility for Python 3.11 environments.
