HPN SDN Controller Link Discovery

HPN SDN Controller Link Discovery

    HP Link Discovery document: HP have released a guide explaining how BDDP is used for link discovery on the HP VAN SDN Controller. This really guide is worth reading. In the past, the HP controller used LLDP and BDDP messages for link discovery. This has changed and only BDDP is now used for link […]

OpenFlow 1.0 and 1

OpenFlow pipelines on physical switches explained – 1.0 and 1.3 on HP ProCurve and Comware switches with the HP VAN SDN Controller

In this video David Bombal demonstrates the configuration of OpenFlow versions 1.0 and 1.3 on physical HP switches. David also explains how HP switches implement single or multiple table pipelines using both OpenFlow 1.0 and 1.3. The OpenFlow pipelines are viewed on both the HP VAN SDN Controller and the HP switches (HP ProVision / […]

OpenFlow switch configuration - HP Procurve and Comware with the HP VAN SDN controller

OpenFlow switch configuration – HP Procurve and Comware with the HP VAN SDN controller

In this video David Bombal demonstrates the configuration of OpenFlow on physical HP switches. Both Comware and ProVision configuration are explained. The switches are integrated with the HP VAN SDN Controller which updates the flow tables on the switches. David explains the OpenFlow flow tables on both the Controller and the switches. The switches used […]

RSdoc – REST API documentation for OpenFlow and SDN

RSdoc – REST API documentation for OpenFlow and SDN

In this video David Bombal explains RSdoc, which provides semi-automated interactive RESTful API documentation. It offers a useful way to interact with REST APIs on the HP VAN SDN Controller, updating OpenFlow flow tables on switches. RSdoc is useful as an API online documentation tool. It provides a catalog of all the REST APIs on […]

Rest API

REST API

In this video, David demonstrates the use of a simple bash script to update flow table entries on OpenFlow switches using the RESTful API and the HP VAN SDN Controller. The HP Controller supports both Java and RESTful northbound APIs. The southbound API protocol used in this example is OpenFlow 1.0.

OpenFlow HP VAN SDN Controller and Mininet integration

OpenFlow: HP VAN SDN Controller and Mininet integration

This video demonstrates OpenFlow integration between the HP VAN SDN Controller and Mininet. The HP Controller is an SDN controller that supports OpenFlow version 1.0 and 1.3. Mininet allows for easy learning and testing of and OpenFlow network emulated on a PC. This is similar in concept to GNS3 or HP Simware.

HP VAN SDN Controller v2.3 released

HP VAN SDN Controller version 2.3 released HP released an updated version of the HP VAN SDN Controller on the 30th of July 2014. This is the third release of the controller in the last 9 months and adds more features. This is a very short introduction – I will be creating more blog entries […]

HP SDN Links

HP SDN and OpenFlow related links:

HP SDN and OpenFlow related links: Here are some useful HP SDN and OpenFlow links and documents. It can sometimes be difficult to find good information, so here is a starting point. I will update this as things develop. Please feel free to contact me with updates you think are good. Some products like Mininet […]

DNS IOS and Ubuntu

Simple DNS solutions for a test or development network

Use Cisco IOS DNS server or Ubuntu DNS server: I recently had to setup a test DNS server for a lab environment. This only had to work for about 20 hostnames. A few options came to mind: Setup a basic DNS server on Cisco IOS in GNS3 Setup a basic DNS server on Ubuntu Setup […]

Spanning Tree and OpenFlow

Questions I often get asked include: Can you run Spanning Tree and OpenFlow together? What happens when Spanning Tree blocks a port? What will OpenFlow do? Will not having redundant links in an OpenFlow network result in loops? Firstly, it is possible to run an OpenFlow network connected to the HP VAN SDN Controller with […]
