Network Programming and Administration using Python


Course Number: PYTH-210

Duration: 3 days (19.5 hours)

Format: Live, hands-on

Networking using Python Training Overview

This Network Programming and Administration using Python training course teaches attendees how to create TCP/IP client and server programs using multi-tasking and multi-threading in Python. Students learn how to use Paramiko, Netmiko, and NAPALM (Network Automation and Programmability Abstraction Layer with Multivendor support) libraries and functions to obtain network device and configuration information, automate SSH tasks to communicate with network devices, and automate network device configurations changes.

Location and Pricing

This course is taught as a private course in-person or online for teams of 3 or more. To receive a quote for online corporate training, please contact us.

In addition, some Programming courses are available as live, online classes for individuals.

Objectives

  • Learn sufficient Python programming skills to write programs that manage and configure network devices
  • Write robust code for multi-tasking and multi-threaded operations
  • Install and use Paramiko, Netmiko, and NAPALM capabilities for managing and configuring network devices
  • Acquire network device information
  • Automate changes to network device configurations

Prerequisites

Participants must be working systems and/or network administrators/engineers/technicians with some experience with fundamental Linux utilities and commands. Python programming experience and working knowledge of a vendor-specific network device (CLI) are useful but not essential.
