Configuration Management

Golden Rule

NEVER apply configuration without first capturing a baseline. If the change goes wrong, you need to know what to roll back to.

Change Workflow

Phase 1: Pre-Change Baseline

Capture the current state of everything the change might affect.

1A: Save Running Configuration

PYATS_TESTBED_PATH=$PYATS_TESTBED_PATH python3 $MCP_CALL "${PYATS_PYTHON:-python3} -u $PYATS_MCP_SCRIPT" pyats_show_running_config '{"device_name":"R1"}'

Store this output — it is the rollback reference.
