Automated SSL/TLS Cert in CVP

Posted on July 11, 2018 by

Hi, since CVP 2018.1 introduced the SSL/TLS certificate management to the web ui I wondered if there is also a supported way to change it via the cli on the system itself? I would like to automatically deploy and update the certificates with letsencrypt. Since the renewal happens every few weeks that would be better done via a cron job than by hand in the gui. I guess replacing the file on disk and then restarting nginx is not the best or supported way for our multinode cluster ;) What would you recommend to to besides buying a certificate with...

Error handling within CVP Configlet builder

Posted on November 23, 2017 by

What’s the best way of handling error conditions in a python configlet builder? My script takes data from a git repository to generate the configlet, the script validates the data before generating the configuration. If it’s invalid it will need to signal an error to CVP. What’s the best way to do this? I’m thinking I should raise and exception, however this simple test doesn’t seem to do the right thing:- <pre> from cvpServices import CvpErrorimport errorCodes CvpError(errorCodes.CONFIGLET_GENERATION_ERROR, ‘error an error occured’) </pre> Any suggestions?

CloudVision Portal RESTful API Client

Posted on September 25, 2017 by

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

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...

Export CVP Functionality to Ansible

Posted on April 14, 2017 by

In some network environments there is a separation of responsibility for the network infrastructure and the server side equipment. In these environments, different groups responsible for managing different equipment could use different tools for the job. This guide will discuss one of the several options for integrating Arista’s network management tool, CloudVision Portal (CVP), into an Ansible environment. Summary In this example, the environment uses Ansible as the configuration management tool for server provisioning but uses CVP for network management. The environment is set up to allow the server team to provision top of rack switch ports for servers using...

Leveraging CVP Telemetry and ZTP in an Ansible Environment

Posted on April 14, 2017 by

This guide will discuss one of several options for integrating Arista’s network management tool, CloudVision Portal (CVP), into an Ansible environment. Summary In data center environments where Ansible is used for configuration management of all devices including networking equipment, the network operations team may want to leverage the telemetry and Zero Touch Provisioning (ZTP) functionality provided by the CloudVision Portal product. In this example, CVP will be used for ZTP, image upgrades, and telemetry while Ansible will be used to manage the switch configuration directly. Documentation for setting up ZTP can be found in the CloudVision configuration guide. Implementation This...

CVP: Editing Configlet Builder

Posted on August 21, 2016 by

I am running CVP 2016.1.1 and I ran into a locking condition which prevent user from modifying the configlet builder once there’s a device attach to that builder generated configlet. My intention was to have a configlet builder script act as a questionaire during initial device deployment.  The configlet builder is a combination of forms and Python script.  The forms will have drop down options providing information for that device.  For example, I created a drop down box name Regions.  It contains values such as AMER, EMEA.  Based on the region values, the Python script will map the respective static configlet(s) to...
