Netmiko and NAPALM are two of the most widely used Python libraries for network automation. Netmiko simplifies SSH connections to network devices, while NAPALM provides a unified, vendor-agnostic API for configuration management and operational data retrieval.
Netmiko is a multi-vendor SSH library built on top of Paramiko. It handles the painful details of interacting with network device CLIs:
| Feature | Description |
|---|---|
| Auto-detection of device type | Identifies prompts and adjusts behaviour |
| Handles pagination | Automatically sends terminal length 0 or equivalent |
| Enter enable mode | enable() method with password support |
| Enter config mode | config_mode() enters and exit_config_mode() leaves |
| Structured output | Integrates with TextFSM for parsed results |
| Multi-vendor | Supports 60+ device types (Cisco IOS/XE/XR/NXOS, Arista, Juniper, etc.) |
pip install netmiko
