Common Issues When Deploying CVX 4.18.2F on vCenter 6 or 6.5

Common Issues When Deploying CVX 4.18.2F on vCenter 6 or 6.5  Summary   This article will go over how to install CVX on a vCenter 6 appliance. Starting from vCenter 6, there was a change in the OVFTool built into vCenter that changes the SHA hashing algorithm from 1 to 256. There is also an issue with 6.5 where it is required to go into the BIOS of the CVX vm and change the boot order from HDD to CD.   The vEOS image (whethere as a vEOS-lab, vEOS for vRouter functionality in Amazon Web Services or Microsoft Azure, or...

Installing CloudVision eXchange (CVX) on Ubuntu / KVM

Introduction This post is intended to give step-by-step instructions on how to install CVX on a KVM Hypervisor on Ubuntu LINUX. The Cloudvision Configuration Guide provides provides excellent instructions on configuring CVX after the install process is complete. You can also browse to the guide via the Support > Product Documentation pages on arista.com. Basic familiarity with Linux is needed in order to complete this task. Installation Procedure Refer to Section 1.1 of the Cloudvision Configuration Guide for host system requirements. Install Steps Download the Aboot and EOS software from https://www.arista.com/en/support/software-download. (CVX is really just an instance of EOS configured with the CVX Server function enabled. Aboot is the boot-loader)...

Deploying Arista Switches using CloudVision Portal

Deploying Arista switches using CloudVision Portal (CVP) Introduction CloudVision Portal or CVP is an automation and orchestration tool for management and deployment of switch configuration across an entire IP based data center network. CVP uses a container hierarchy for organizing devices into logical groups and splits the device configurations into ‘configlets’ which can be applied at varying levels of the hierarchy to provide inheritance and de-duplication of effort when developing device configuration. This approach reduces human error thru inheritance of configuration. Operators can focus on the device specific configuration, knowing that general configuration, such as, AAA, domain name and DNS...

VXLAN Without Controller for Network Virtualization with Arista physical VTEPs

  1) Introduction This article assumed an understanding of the VXLAN concepts. This article aims at guiding the design and implementation of network virtualization with VXLAN, employing physical VTEPs. This controller-less design provides Layer2 communication across a Layer3 network for any Layer2 Ethernet device. This solution guide resolves network virtualization for network teams that might not have yet a network virtualisation controller, or cloud management platform (CMP), but want to benefit now from all the advantages of VXLAN. Without network controller, the virtual switches will not participate natively in the VXLAN overlay setup, they would be configured the traditional way...
