Introduction to guestshell.10.3.3.F.ova Software
This OVA package (guestshell.10.3.3.F.ova) provides a secure Linux container environment for Cisco Nexus 9000 series switches running NX-OS 10.3(3)F+ releases. Designed for DevOps workflows, it enables execution of custom Python scripts and third-party utilities within isolated sandboxes while maintaining native switch functionality.
Cisco’s release documentation confirms version 10.3.3.F implements Kubernetes CRD integration, allowing containerized applications to directly interact with ACI fabric policies through APIC’s northbound APIs. Compatible with Nexus 9300-EX/FX and 9500-GX platforms, it supports automated service chaining for L4-L7 network functions.
