Netmiko

Netmiko is an open-source Python library that simplifies SSH connections to network devices from multiple vendors, including Cisco, Juniper, Aruba, and many others. It handles the complexity of establishing SSH sessions, sending commands, and capturing output in a consistent way regardless of the underlying device type, eliminating the need to write custom connection code for each vendor. Netmiko is one of the most widely used Python libraries in network automation and is often the first tool network engineers learn when starting to automate CLI-based device interactions.
