All, thank you for the feedback. I’m glad to hear that this is useful.

Matt, thanks—I’ll give that a try, and see if its helpful.

Prashant, have a look at this post (http://blog.scottlowe.org/2012/10/31/layer-3-routing-with-open-vswitch/); it has the information you need on VLAN interfaces with OVS.

In response to “What are these commands doing, exactly? This is the part that I couldn’t find documented (well) anywhere. I saw lots of references to ovs-vsctl parameters like set interface or set port, but no clear explanation of what these commands were doing, or why.”

I was stymied by the same problem, in part due to the poor manpage formatting on the Open vSwitch website. The ovs-vswitchd.conf.db(5) manpage is what you’re looking for — except you’ll want to look at it using good old-fashioned “man” rather than online.

I have been trying to understand OVS myself and I couldn’t agree more with you.

Your article is very very helpful. Thank you!

Great article. It should be very helpful to anyone familiarizing themselves with the Open vSwitch – I struggled for a day to figure out the LAG configuration.

I noticed your reference to my article on configuring sFlow. The Open vSwitch supports both sFlow and NetFlow and anyone looking to monitor virtual switch performance might be interested in a more recent article describing how to configure both methods of monitoring and comparing the results you can expect:
