(NOTE: I keep calling the config_textfile "config dot textfile". This is of course an error haha. That was the original name of the file when I first created the demo, but decided to change it to an underscore)

Hi. Thanks for the video. How can we capture exceptions? Incase of failed tasks. I will like to capture exceptions and put them into a txt file

Hi, just wondering if you are releasing a video with enable on cisco devices password protected. I am having trouble with dynamically assigning the enable secret for netmiko. If I add it on the yaml file it works but requesting is using = is not working where pwd = getpass()

Why do you use eve-NG and not gns3. Is it better in any way or just preferences? I never tried eve. Eve GUI looks nicer.

Hi John, Quick question.. the section at 4.21 where we can edit the ip address, can we reference that section to another txt file where we have some specific IP addresses from different subnets?

nice tutorial but you could have put the username/password in default.yaml, to make this host file clean and avoid typing credentials for 1000 devices
