Hello? I am a beginner of Arista switch. I have two questions on that.


1) How can I dump ovsdb on Arista switch?

2) I drew a diagram for self understanding of cvx, hsc and Arista switch. Is that right?



   |          HSC       |

   | (ovsdb server)|


   |         cvx          |


   | Arista Switch |

Hi Jeff,

CVX supports HSC schema so you just need to point at CVX.

Are you trying to integrate with VMware NSX, Openstack, Nuage, Plumgrid? Or are you trying to run something else, maybe custom?

CloudVision eXchange (CVX) would show you/represent/deal with the rest of the Arista physical switches for :

– finding the MAC addresses 

– finding the physical host in the topology (LLDP)

– provisioning VLANs, L2 trunks, and VXLAN VNIs, flood lists, etc.

OVSDB would provide not just overlay network instructions but also Layer2 reachability. Some controllers would also send Layer3 instructions.

That’s how it would normally work in the integration with Cloud Management Platforms such as the ones mentioned earlier.

Could you clarify what you are trying to achieve?

Hi, Alexis

Thank you for replying with this posting.

First of all, I read the manual for integrating with Arista and NSX via ( -> Module 4 (INTRODUCTION TO HARDWARE VTEP WITH ARISTA) <- This is a public site… and there are several terminologies which I’ve firstly seen like cvx and hsc…

So for better understanding myself, I just tried to draw its hierarchy or communication channel between them. I attached the questions as pdf file to more visualize what I understood. please take a review if you have a time.

Could you clarify what you are trying to achieve?

-> I am not familiar with Arista switch including cvx, hsc etc so that I just would like to get visualize how it works. and first question is based  on that I also found someone gets ovsdb dump on HP switch which integrated with NSX or else to see how its communication works. So that curious to know how to get ovsdb dump on Arista switch too. I’ve never found its commands on user manuals. That’s it. A beginner’s passion to learn.

Thank you
