Python Network Automation

Python is not the only language being used for network automation but the combination of being an easy to learn language, and many code samples and utilities has made it a go-to language for network engineers. Checkout all the resources available for developing with Python and Cisco Networking!

Explore Python sample code

On-Box Python

Example scripts that leverage Cisco provided Python libraries allowing access to the configuration, operational state, or event data from the network element.

Execute CLI via Python

Leverage the CLI library to execute the “show version” command on the box.

TDR Test Every Interface

Leverage the CLI library with a TDR test run on every interface in “up” status.

EEM Config Changes to Spark

Monitor configuration changes and send a message to a Cisco Spark Room.

Check out repo

Off-Box Python

Examples that leverage one of the many exposed interfaces (NETCONF, RESTCONF, SNMP, SSH, etc) on a network element within a script.

MIB Walk with Python

Perform a MIB walk against a device leveraging the “netsnmp” library.

NETCONF Connection with Python

Connect to a device with NETCONF using the “ncclient” library for Python.

Configure Interface IP Address with RESTCONF

Use RESTCONF to configure the IP address on an interface.

Check out repo

Python & Network Controllers

In addition to using Python to automate device by device, Python can be used to interact with Network Controllers such as APIC-EM, APIC, or OpenDaylight.

Get Inventory from APIC-EM

Retrieve inventory database information of the entire network using the REST API.

Get Host List from APIC-EM

Query and display a table of all clients connected to network devices.

Retrieve Tenants from ACI APIC

Leverage the ACI Toolkit to retrieve the list of tenants configured on an APIC controller.

Check out repo

Develop with Python SDKs and Tools

ACI Toolkit

The acitoolkit exposes a subset of the ACI object model in a way that is meant to provide an introduction to the ACI concepts and allow users to get the most common workflows up and running as quickly as possible.

Get started with ACI Toolkit

Cobra SDK

Cobra is a Python SDK that provides the developer with native ways to interact with the ACI API and object model. With Cobra, developers can quickly build powerful applications against ACI fabrics.

Get started with Cobra SDK

NX Toolkit

The NX Toolkit is a set of python libraries that allow basic configuration of the Cisco Nexus Switch. It is intended to allow users to quickly begin using the REST API and accelerate the learning curve necessary to begin using the Switch.

Check out repo

YANG Development Kit

YANG Development Kit (YDK) was developed to facilitate network programmability using data models. YDK-gen takes YANG models as input and produces Python APIs (YDK-Py) that mirror the structure of the models.

Check it out

Learn YDK with Python for NETCONF/YANG

Hello World for YDK-Py

A collection of sample applications that use YDK-Py for network programmability. The hello-ydk.py script prints the uptime of a device running Cisco IOS XR.

Basic YDK-Py Apps

These apps illustrate simple examples of using YDK-Py to program a network device. They do not require significant model or programming experience.

YDK Learning Lab

Leveraging YANG Development Kit (YDK) for Programmatic Access to Network Devices.

Get started with On-Box Python and GuestShell on IOS XE
