Introduction to guestshell.10.2.7.M.ova
This OVA package delivers Cisco’s Guest Shell 10.2(7)M – a secure Linux container environment for Catalyst 9000 Series switches running IOS XE Amsterdam 17.12.x+. Designed for network operators requiring custom automation workflows, this maintenance release resolves 6 critical vulnerabilities identified in Cisco’s 2025 security advisories while maintaining backward compatibility with 10.2(x) container configurations.
Compatible with VMware ESXi 8.5U1+ and KVM 4.4.0+ hypervisors, the virtual appliance provides preconfigured Python 3.11 and Docker 24.0 runtime environments. Cisco officially recommends this build for organizations implementing Zero Trust Architecture through automated policy enforcement workflows.
