Device auto detect

Netmiko provides a mechanism that can guess the device type and detect it. It uses a combination of SNMP discovery OIDS and executes several show commands on the remote console to detect the router operating system and type, based on the output string. Then netmiko will load the appropriate driver into the ConnectHandler() class:

#!/usr/local/bin/python
__author__ = "Bassim Aly"
__EMAIL__ = "basim.alyy@gmail.com"


from netmiko import SSHDetect, Netmiko

device = {
    'device_type': 'autodetect',
    'host': '10.10.88.110',
    'username': 'admin',
    'password': "access123",
}

detect_device = SSHDetect(**device)
device_type = detect_device.autodetect()
print(device_type)                   
print(detect_device.potential_matches)

device['device_type'] = device_type
connection = Netmiko(**device)

In the previous script:

• The device_type inside the device dictionary will be autodetect, which will tell netmiko to wait and not load the driver till the netmiko guesses it.
• Then we instruct the netmiko to perform device detection using the SSHDetect() class. The class will connect to the device using SSH and will execute some discovery commands to define the operating system type. The returned result will be a dictionary, and the best match will be assigned to the device_type variable using the autodetect() function.
• You can see all the matching results by printing the potential_matches.
• Now we can update the device dictionary and assign the new device_type to it.
