With Hardware VTEP being implemented in, well, hardware, how things work depends on capabilities of the underlying chipset. This means that when we design solutions using these products, we need to keep these capabilities in mind and configure things accordingly.
In this short post I’ll cover a situation we’ve encountered at one of our customers where things “should” have worked but didn’t, and what was the reason for that.
This post is next in series on using HW VTEPs with NSX-v. You can find earlier posts here: 1, 2, and 3.
Today we’ll look at a couple of choices you’ll need to make when deploying Brocade’s HW VTEP, and then check if our configuration is correct before linking it with NSX-v next time.
In a couple of previous blog posts, we’ve looked at the use cases for HW VTEPs. Now, let’s start digging a bit deeper.
In this instalment, we’ll have a look at what things you need to think about when planning your Hardware VTEP deployment. While I’ll be using Brocade VCS as the HW VTEP for this post, some of this info should be applicable to other Vendors’ solutions.
VMware NSX for vSphere has been shipping beta support for hardware VTEPs since version 6.2.0, with General Availability (GA) coming in the next few months. With this in mind, I thought it would be useful to provide an overview of HW VTEP’s use cases and considerations.
