It’s a script that helps you to backup each of your switch running configuration one at a time.
Before running the script, you must manually enter the file path on line 48.
For example, if I need to store the running configurations on a folder called “SW_config” under /usr/user/Desktop/, I should enter “/usr/user/Desktop/SW_config” as my file path.
2) What to do with “device_list.txt”?
This file stores your switch IP, account, and password. Your script will reference this file when performing configuration backup.
For instance, you should see the following two switch’s IP and credential:
Script reads these information line by line.
Each variable should be separated with a comma (,) and do not leave any space.
3) What to do with “AutoBackupConfig.bat”?
In order to make your Task scheduler working, creating a .bat file is necessary.
We need to put “Path to Python3” (space) “Path to your script” in it.
To get the path of Python, type where python in command prompt.
