Cisco DNA Center Healthcheck Device Netconf

Cisco DNA Center Healthcheck over Netconf-Yang from Console

This script verifies connectivity between Cisco DNA Center and the Network Device.

If Discovery fails on Netconf-yang (on Cisco DNA Center UI) for Network Device, then this script could verify that netconf-yang (port 830) is reachable from the maglev console (Cisco DNA Center). If it's not reachable, then there will be error logs with details from the ncclient module in python (timeout, credentials, port, etc.)

This script is used as an advanced troubleshooting tool, for the experienced Cisco DNA Center administrator.
