Recently, we talked with you about using Python for network programming. Let me share you an simple example of a Python script, which helps me a lot in my work. Before every course the trainers have to check the lab operation. The next week I will deliver the CCEA (Cisco Contact Center Enterprise Administration) course to seven students, and every student will use his individual lab pod. In the pod there are 13 virtual machines and hardware devices. Before we start the course I have to be sure that all VM are accessible through the network, so I have to connect to every lab pod and ping all the VMs and devices there. Of course, I can do it manually, however, it is time consuming. Let's use Python to automate this and save our time.

Python for Network Programming
The era in which a network engineer only had to manage or configure one device at a time is quickly disappearing. With the growth of network devices, the adoption of cloud, and the desire of companies to be more flexible for a competitive edge in their market, the old ways of performing network management do not work anymore.
If you examine the way devices have been managed for 20 years, you can see that there has been no good way to manage machine-to-machine communication with the network. Usually, device configuration by network engineers generally looked like the process below:

Hello!
Not so long ago, I helped my friend to configure a Cisco router in their office to connect to their Internet Service Provider (ISP) via ADSL. They had a UC520 SMB router installed, which needed to be connected to the ISP via an ADSL modem. A diagram of that connection is shown in the figure above.
