Notice: For information specific to IOS-XE HTTP Vulnerability please see this link

Note: Thank you for continuing your support of the DNAC-Template Repository by your continued visits to the site. Over the past few years we have developed a lot of content as a result, it is time to reorganize it to help be more consise, and to aide users in finding the relevant content easily. Over the next few months you will notice changes and updates to the repository, as we add additional content, revise existing dated content and nomenclature. The folder structure and resources will be reorganized for ease of use, and so that CODE examples and TUTORIALS will be grouped together for ease of use. We hope this will help users to find the content they need in an easier manner.

Cisco Catalyst Center

Cisco Catalyst Center Overview

Cisco Catalyst Center is an intelligent Automation and Assurance platform for the campus. Cisco Catalyst Center enables, simplified Day-0 through Day-N management of switching, routing, and wireless infrastructure. It also improves operations with AI/ML-enhanced analytics to streamline troubleshooting and provide actionable insights into the health of the network and the quality of experience for users and applications. Here are some of the capabilities of Cisco Catalyst Center in their respective domains:

  • NetOps: Network Plug and Play for Zero Touch Deployment, Software Image Management, Compliance, Configuration Templates and Network Profiles, Model-Driven Configuration, and RMA Support.
  • AIOps: AI/ML-enhanced monitoring and troubleshooting support. Predictive Insights, Network Baselines, Network Reasoner, Device/Client/Application 360, Intelligent Capture.
  • SecOps: AI Endpoint Analytics, Group-Based Policy and Analytics, Software-Defined Access
  • DevOps: ITSM Integrations, APIs, SDK & Ansible Module

Overview

This Repository will give examples of templates used in Cisco Catalyst Center that can be modified. Additional information will be included to hopefully give a well rounded explanation of Automation methods with Templates using Cisco Catalyst Center and flows with both Onboarding and DayN Templates and concepts.

The repository will include scripts and examples with the following:

  1. Template Scripting for both Jinja and Velocity
  2. Variable notation and usage
  3. Binding Variables
  4. System Variables
  5. Regular Templates
  6. Composite Templates

The goal of this repository is a practical guide to allow engineers to rapidly begin using Cisco Catalyst Center automation and begin conversion of IOS CLI Templates. The Templates have been developed over the years and with various use cases in mind, and so the intent of sharing this collection is to reduce the lift to begin automating.

Intent Based Networking

Either one or multiple Templates may be used to deploy Intent in combination with the Design Settings and Policies deployed within the UI. One or Multiple templates may be used in Onboarding (PnP) or Day N methods. Day N methods are designed for making ongoing changes and may require 'no' statements depending on the configuration construct being modified.

Additionally:

  1. Intent can be defined as the set of code along with the configuration constructs deployed via a template.
  2. Variables can be used to modify or choose between constructs deployed via decision (‘IF’) statements
  3. Repetition of any construct may be introduced through the use of Looping structures on any device.
  4. Variables may be used when the device is being onboarded or provisioned

DNAC Template LABS

This section built out in a lab format to guide you through the typical steps to complete various automation tasks delivered by Cisco Catalyst Center. It allows for customers to practice Cisco Catalyst Center workflows with Onboarding, DayN Templates, and Application Policy automation on both Wired and Wireless Platforms, while reducing the time and effort needed to instantiate the network The lab will also introduce advanced velocity templating topics and troubleshooting tools, which may help determine common failure scenarios in a deployment.

New Catalyst Center Lab Content

This newer and more modular lab approach is designed to deal with and includes concepts from the legacy labs in a newer more modular format.

  1. Lab 1 Wired Automation - Covers green and brown field use cases (allow 4.0 hrs)
  2. Lab 2 Wireless Automation - Covers traditional wireless automation (allow 4.0 hrs)

Legacy Lab Content

In this section you will continue to find all the existing labs which deal with specifics in separate easy to do labs.

Practical Template Examples

In this section I have compiled a number of template examples built with Jinja2 Language. These samples include a wide ranging set of configurations which may be used in your labs to solve specific configuration requirements. This collection summarizes aspects covered previously in this templating repository, and are aimed at providing quick practical references to help engineers solve automation tasks with the help of Cisco Catalyst Center. Additionally these examples may be used in testing in dCloud with any of the labs on this repository.

DNAC Templates Store

This repository is built out to share Cisco Catalyst Center Templates and allow for ongoing submissions from those inclined to share their work with the community. Initially the repository includes all the examples that we have used in this repository in RAW TEXT and JSON format. After your first submission you will be able to continually add your templates as you develop new and interesting approaches to device management.

Please maintain the directory structure with submissions. If you have a suggestion please reach out and contact me.

Please use this menu to navigate the various sections of this separate DNAC Templates Store Github repository. Within the multiple folders are examples, explanation readme files for reference.

  • RAW TEXT Examples - Templates in raw text for editing
  • DAY ZERO JSON - JSON files for easy import to Cisco Catalyst Center for Day Zero
  • DAY N JSON - JSON files for easy import to Cisco Catalyst Center for Day N
  • REGULAR JSON - JSON files for easy import to Cisco Catalyst Center for Day N
  • COMPOSITE JSON - JSON files for easy import to Cisco Catalyst Center for Day N

DCLOUD as a LAB

Overview

As a quick start with Cisco Catalyst Center Automation, you may utilize the above labs in conjuction with DCLOUD's sandbox:

  1. Cisco Enterprise Networks Hardware Sandbox West DC
  2. Cisco Enterprise Networks Hardware Sandbox East DC

This allows you to run these labs and gives not only an environment to try the various code samples, but also to develop and export your own code for use in your production environment. DCLOUD provides for rapid and safe POC/POV on-demand environment without impacting production environments. DCLOUD also negates the need for shipping equipment, associated lead times, and licensing issues associated with setting up your own private testing environment. Please do adhere to the best practices for the DCLOUD environment when using it.

DCLOUD allows for use with a web-based browser client for VPN-less connectivity, as well as AnyConnect VPN client connectivity for those who prefer it. The labs are hosted in Cisco San Jose Facility (Select US East or US West Region when scheduling in DCLOUD). Choose the Cisco Enterprise Network Sandbox version you prefer.

Note: To access this or any other content, including demonstrations, labs, and training in DCLOUD please work with your Cisco Account team or Cisco Partner Account Team directly. Your Account teams will make sure the session is scheduled and shared for you to use. Once booked follow the guide within Github to complete the tasks adhering to the best practices of the DCLOUD environment.

Examples

These examples must be used with two conditions:

When building the template you will need to select a scripting language. Specific examples of Templates in the two scripting languages supported are available in the following folders:

The conditions that they are used are documented and are explained in Onboarding Templates and examples of DayN Templates are explained in DayN Templates
