Deep Dive into Cisco Network Programability

Inspired by Netmiko & Netdev to make scripts run much faster

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites:

• Linux OS (Recommended for Ubuntu 18.04)
• Python >=3.5 (pre-installed)

python3 --version

• SSH enabled and tested (connectivity)

ssh cisco@192.168.1.10

Installing:

• Download the repository into a directory

git clone https://github.com/omarthe95/DeepDive.git

• Run setup.sh

bash setup.sh

• Edit IPaddress_Switches.txt file with your own IP address, each device IP per line

nano IPaddress_Switches.txt

• You may change the access credentials inside each python script individually, because the default access credentials into network devices is cisco:Cisco123

Running the Scripts

We will start with each script with GIF to see it function

Sequential.py

Entering each device (one-by-one) take so much time

python3 Sequential.py

MultiThreading.py

But executing it with Threads for each independently device of one another makes it faster

python3 MultiThreading.py

Asyncio_Netdev.py

Concurrent the code with Asyncio that runs in a single thread will go beyond faster

python3 Asyncio_Netdev.py

MultiThreading vs. Asynchronous
