Setting Up CVP

Note: Single-Node is not recommended for production deployments.

Pre-installation Checklist

  • Ensure that you have console access to the CVP virtual machine on each appliance, via WOK web access. See Web Access into CVX and CVP Consoles via WOK.
  • Enter the CVP Console.
  • Ensure all configurations are done via console and not via SSH.
Note: This configuration will change the IPs and will drop connectivity if done over SSH.

Setup Steps for Single Node CVP

To set up single node CVP, complete the following steps.

  1. Access the primary CVP VM via WOK.
  2. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of a Single-Node.

Setup Steps for Multi-node CVP Cluster

Assign to each of the three CVP VMs a role (primary, secondary or tertiary).

  • The roles may be assigned in any way, but the roles must be kept consistent throughout the installation. No two nodes may share the same role.
  • Maintain the installation order starting with primary, then secondary, and finally tertiary.

To assign the roles, complete the following steps.

  1. Print the CloudVision Worksheet. Circle the role of each appliance: one primary (P), one secondary (S), and one tertiary (T).
  2. Access the primary, secondary, and tertiary CVP VMs on the respective appliance via WOK.
  3. Refer to the CloudVision Configuration Guide for the Shell-Based Configuration of Multi-Node.

Log into the CVP Web Interface

After CVP is running on the multi-node appliance cluster, enter the CVP Web Interface of the primary node via its CVP IP/Hostname with default username/password of cvpadmin/cvpadmin to set the password.

For Multi-node clusters, setting the password only has to be done on one node, and is synced to other nodes so subsequently any node can be accessed via its web interface. Refer to the CloudVision Configuration Guide for instructions on using CVP.

Site Selection

Read the safety instructions in your Safety, Environmental, and Regulatory Information booklet before you begin.

The following criteria should be considered when selecting a site to install the appliance:

  • Before you begin, review the safety instructions located at https://www.arista.com/en/support/product-documentation.
  • Begin installing the rails in the allotted space that is closest to the bottom of the rack enclosure.
  • Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
    • Clearance areas to the front and rear panels allow for unrestricted cabling.
    • All front and rear panel indicators can be easily read.
    • Power cords can reach from the power outlet to the connector on the rear panel.
Note: All power connections must be removed to de-energize the unit.
Note: This unit is intended for installation in restricted access areas.
