Netmiko

Netmiko is a Python library built on top of Paramiko, which simplifies automating network device configuration and management tasks. It is designed to work with Cisco, Arista, Juniper, and other network vendors.

Examples

Here are a few examples of how Netmiko can be used to interact with Cisco routers:

  • Connecting to a Cisco router: Netmiko can be used to establish an SSH connection to a Cisco router. Here's an example of how to connect to a router using Netmiko:
from netmiko import ConnectHandler

# Define the device parameters
device = {
    'device_type': 'cisco_ios',
    'ip': '192.168.1.1',
    'username': 'admin',
    'password': 'password',
}

# Connect to the device
net_connect = ConnectHandler(**device)
  • Running commands on a Cisco router: Once connected, Netmiko can be used to run commands on a Cisco router. Here's an example of how to run the "show version" command on a router:
output = net_connect.send_command("show version")
print(output)
  • Configuring a Cisco router: Netmiko can also be used to configure Cisco routers. Here's an example of how to configure an interface on a Cisco router:
# Define the configuration commands
commands = [
    'interface FastEthernet0/1',
    'description Configured by Netmiko',
    'ip address 192.168.1.10 255.255.255.0',
    'no shutdown'
]

# Send the configuration commands to the device
net_connect.send_config_set(commands)

Netmiko provides a simple and consistent interface to interact with network devices and automate tasks such as configuration management, backup, troubleshooting and more. It supports a wide range of network vendors and platforms, and it includes support for SSH, Telnet and serial connections.
