Python Programming for Cisco Networking Engineers

Engineers who implement software-based technologies in a Cisco enterprise or configure and manage network devices.

After you complete this course you should be able to:

• Write and test several functional Python scripts.
• Write, edit, modify, and expand complex Python scripts to utilize APIs and data models.
• Use the following APIs to automate configuration and management of Cisco networking devices:
  • Paramiko
  • REST
  • XML
  • JSON
  • NETCONF
  • RESTCONF
• Use the YANG and MIT data models to read and manage objects to automate configuration and management of Cisco networking devices.
• Automate configuration of multiple Cisco devices.
• Use the following DevOps / learning tools to enable efficient use of APIs and data models and effectively create Python scripts:
  • Postman
  • IDEs for both Windows and Linux
    • Notepad++
    • Sublime
    • PyCharm
    • Microsoft Visual Studio
    • Anaconda
    • Linux VI Editor
  • Lint tools for XML and JSON
  • Visore for Cisco Data Center
  • API Inspector for Cisco ACI
  • YANG Validator

 

Attendees should meet the following prerequisites:

• Knowledge of Cisco networking devices is required. ICND1 Recommended
• Knowledge of ACI is useful. INTACI Recommended
• Knowledge of programming or Python is NOT required
