Python Script to find Cisco IOS facts

 Today I need that I should find one of the device Serial Number, Uptime, Vendor, Model & Hostname. I found Napalm module is the best and simplest way to connect device and get the IOS facts. I will work on all the Napalm modules and try to create some scripts and share it with everyone. 

Script: 

import json

from napalm import get_network_driver - Napalm Module

driver = get_network_driver('ios')

iosvl2 = driver('X.X.X.X', 'username', 'password')

iosvl2.open()

ios_output = iosvl2.get_facts()

print (json.dumps(ios_output, indent=4))

iosvl2.close()

Output:
