Automating network configuration updates is powerful—but risky—especially with platforms like Cisco IOS that lack native, atomic config replacement. In this session, Michael Schwartzkopff shares a practical and resilient approach to managing full-device configuration from NetBox to Cisco IOS. By leveraging NetBox for config generation, scripting secure deployments, and creatively applying the config archive feature, the solution ensures automatic rollback if connectivity is lost. This talk is ideal for engineers seeking safe, hands-off deployment techniques in brownfield Cisco environments, and demonstrates how a NetBox-centric automation stack can reduce operational risk without sacrificing control.
