Introduction to guestshell.10.2.6.M.ova
This 1.2GB OVA template provides a containerized Linux environment for Cisco IOS XE 10.2(6)M deployments, enabling secure third-party application execution on Catalyst 9000 Series switches. Released in Q1 2025, it implements FIPS 140-3 validated cryptographic modules while maintaining backward compatibility with IOS XE 17.9(1)+ environments. The package (SHA256: 8d4f2…e9a31) isolates Python/REST API operations from core network functions through hardware-enforced resource quotas.
Designed for zero-trust architectures, this version supports automated compliance auditing with Cisco DNA Center 2.3.7+ and integrates natively with ThousandEyes enterprise agents. It specifically addresses healthcare and financial sector requirements for HIPAA/PCI-DSS compliant network automation workflows.
