Synchronising CloudVision Portal Configlets with Ansible

Posted on February 19, 2020 by Hugh Adams | 1608 Views

Introduction As customers deploy Arista devices across multiple locations it becomes important to consider where and how these are managed. In most circumstances more than one instance of CloudVision Portal (CVP) will be required as this allows for multiple fault domains and redundancy within the management plane. This article will explore the use of the Arista CloudVision Ansible modules to synchronise a designated set of CVP Configlets across multiple CVP instances. This ability to synchronise Configlets provides an efficient way of ensuring organisational policies and security requirements can be quickly deployed across an entire Arista estate in a consistent automated...

CVP TIP – Encrypt local username passwords with Configlet Builder

Posted on March 20, 2019 by Markku Rantanen | 1153 Views

Introduction Arista CloudVision Portal (CVP) uses configlets to create configuration snippets for individual or groups of switches based on user selection. These configlets can be either static or dynamic. Static configlets include static EOS CLI configuration statements as if they were right on the switch configuration file. These configlets are used to create the full configuration for the network switches. An example of a static configlet in Arista CloudVision Portal: Below example is a static Arista EOS CLI configuration. These small pieces of configuration snippets can be applied as configlets in Network Provisioning view to selected device or devices....

Using CloudVision Portal to Manage Arista AnyCloud

Posted on February 4, 2019 by Michael Sparacio | 454 Views

Introduction There are many advantages to using Arista’s vEOS Router and CloudVision Portal (CVP) in hybrid cloud environments. Among those advantages are: Arista EOS is a proven and stable network operating system used in some of the largest networks in the world. The same EOS that runs on our physical switches also runs in the public cloud. CloudVision Portal provides a common management model for network devices whether running in a customer’s private data center or in public cloud environments. CloudVision Portal provides turn-key automation and real-time telemetry across private and public cloud environments. One of the primary challenges to...

An Exercise in Troubleshooting With CVP Telemetry

Posted on September 25, 2018 by Brian | 1556 Views

In a previous post, I demonstrated the ability of CVP Telemetry to do automatic analytics and event correlation. While each release of CVP includes additional analytic, event correlation, and visualization capabilities, there are still situations for which there is not yet automatic correlation. In this post, we are going to investigate a network problem and identify the root cause using telemetry data. The lab topology is a layer3 spine-leaf topology with 2 spines and 6 leafs configured as 3 MLAG pairs. As stated in the previous post, Cloud Tracer is a very useful tool for tracking the operational status of...

CloudVision Portal RESTful API Client

Posted on September 25, 2017 by Matthew Hartzel Hartzel | 5639 Views

Arista Cloudvision® Portal (CVP) provides a central point of management for Arista network switches through shared snippets of configuration (configlets) enabling Network Engineers to provision the network more consistently and efficiently. While CVP highlights a graphical user interface for configuration and management of devices, it also includes a full-featured RESTful API that provides all of the same functionality available via the GUI which can be used to automate workflows and integrate with other tools. CVPRAC is a wrapper client for CVP’s RESTful APIs which greatly simplifies usage of the API and more elegantly handles the connections to the CVP nodes....

CVP APIs: A Non-Programmer’s Guide

Posted on August 31, 2017 by Olufemi Komolafe | 2030 Views

1. What are CVP APIs? Most CloudVision Portal (CVP) users are familiar with the web user interface (UI) that facilitates network provisioning, inventory management, tasks management, change control and so on. CVP application programming interfaces (APIs) offer an alternative means of realizing the same functionality. The key difference is that, with the CVP APIs, the functionality is realized over a programmatic interface (i.e typically by a piece of software communicating with another piece of software) rather than by a user navigating over a web page and clicking and/or typing. Figure 1 shows a simplified example of these two methods of...

Using dynamic Ansible inventories to manage CloudVision switches.

Posted on June 5, 2017 by Daniel Hertzberg Hertzberg | 1479 Views

Ansible Dynamic libraries with CloudVision The common question when talking with customers about CloudVision is are we able to also use a configuration management tool such as Ansible along with CloudVision? You can use CVP and Ansible to both manage your Arista devices. This is a guide to dynamically pull CloudVision for its devices and automatically have Ansible use those CVP managed devices. Arista has supported Ansible EOS modules for quite some time and are still innovating on new modules in the latest version of Ansible which at the time of writing is 2.3. Summary Dynamic inventories are setup in Ansible...

CloudVision Automated snapshot using Cloudvision API

Posted on March 20, 2017 by shalin | 707 Views

Purpose The purpose of this document is to build an automated task to create container based snapshots using the CloudVision API along with a scheduled cron job from any reachable Unix/Linux/Mac server. This script will come in handy to compare network status/configuration of your entire network by taking snapshot on a predefined schedule and can be modified if an administrator’s requirements change. After we create a snapshot template in CloudVision (by default, CloudVision uses the show_inventory template, but can be customized with the desired set of commands), we will write a simple Python script that leverages the snapshot template to perform...

Datacenter Deployment Automated

Posted on March 8, 2017 by Werner Viljoen | 2117 Views

Planning Methodology There is a lot of talk about automation in the datacenter which indeed saves time but a lot of effort still goes into planning. After all, failing to plan is planning to fail. I needed a way to start automating some of the planning and repetitive tasks needed for deploying the same blueprint across various sites. One of the bigger tasks is the IP Plan and making sure that the correct IP’s get used in configurations. Additionally making sure that the same methodology gets used on different sites. Initially, I set out to use a very nice utility...
