Introduction to guestshell.10.2.7.M.ova

This OVA package delivers Cisco’s Guest Shell 10.2.7.M container environment for Catalyst 9000 series switches running IOS XE Amsterdam 17.9.x and later. Released in Q4 2024, it provides a secure Linux-based sandbox for running Python automation scripts and third-party applications without impacting core switch operations.

Designed for network automation workflows, the container supports Docker-compatible tools while maintaining full separation from the host IOS XE system. It inherits Cisco’s Application Framework (CAF) architecture for resource-constrained environments.

Key Features and Improvements

  • Patched OpenSSL 3.0.14 vulnerabilities affecting REST API communications
  • Added certificate chain validation for container registry access
  1. ​​Performance Optimization​​
  • Reduced memory footprint by 18% through Alpine Linux 3.19 base OS updates
  • Improved Python 3.11 runtime threading for NETCONF/YANG operations
  1. ​​Toolchain Enhancements​​
  • Pre-installed Ansible 8.6 with Cisco NSO integration modules
  • Added gNMI collector service for telemetry data aggregation
  1. ​​Diagnostic Capabilities​​
  • Extended guestshell-monitor CLI command with TCAM utilization alerts
  • Integrated syslog-ng 4.5 for container-level logging granularity
