Overview
NAPALM (Network Automation and Programmability Abstraction Layer with Multi-vendor support) allows engineers to write automation code that works across different vendors without needing to know the specific CLI commands for each.
Key Features
- Getters: Standardized methods to retrieve information (e.g.,
get_facts(),get_interfaces()). - Configuration Management: Supports 'replace' and 'merge' operations for configuration changes.
- Dry Run: Allows you to see the changes that would be made before applying them.
Importance
NAPALM promotes vendor interoperability and reduces the complexity of managing heterogeneous network environments.
