What Netmiko is

Netmiko is a free Python library for automating command-line connections to network devices. It simplifies SSH connections and documents supported Telnet device types. The library is designed to collect output from show commands and make configuration changes while handling low-level device state. Its platform list covers many vendors, grouped by regular, limited or experimental testing status. Regularly tested examples include Arista vEOS, Cisco IOS, IOS-XE, IOS-XR and NX-OS, Juniper Junos, and Linux. Documentation covers pip installation, API use and secure copy support, and links to a tutorial for using Netmiko with TextFSM. Examples show running commands such as “show ip int brief” and sending configuration command sets. Netmiko Tools can encrypt sensitive YAML values using Fernet or AES128, with guidance to protect the key and keep it out of version control. Optional package extras support the bulk-encryption CLI and Paramiko 4 compatibility. The project uses the MIT license; bug reports and feature requests go through GitHub issues, while general questions are directed to its Slack channel.
