Uses the Netmiko Python library to connect to a device, retrieve the config and save the results to a text file.
The config_type variable can be changed as necessary (from "running" to "startup", etc.
)
get_device_config.py runs asynchronously with concurrent.futures thread pools. The number of threads can be adjusted with the max_threads variable.
device_list.py is provided as a template for externally storing the necessary device connection information as a list of Python dictionaries. It currently consists of two Cisco always-on sandbox
devices whose usernames and passwords change periodically, so YMMV if using them to test.
config_diff.py creates a side-by-side html diff of two files, color-codes additions, deletions or edits and optionally opens the diff in the default web browser.
