I love simple automation and scripting.
In this example, we had to audit thousands of network devices for a specific configuration line. Doing this by hand would take hours, with Python it takes minutes. (Yes, we will automate the fix at some point).
Basic conditions and loops combined with a handful of network libraries and regular expression knowledge can go a long way to making a more productive day.
#!/usr/local/bin/python3 from netmiko import Netmiko from getpass import getpass password = getpass() input = open('washu-3850-inventory.txt', 'r') for i in input: output =  devices = i.split() if devices: try: net_connect = Netmiko(host=devices, username="myusername", password=password, device_type="cisco_ios") net_connect.find_prompt() except: next output.append(net_connect.send_command("show run | inc frame", use_textfsm=True)) if output: print("Found on " + devices + " " + output) else: print("Not found on " + devices)
