Prepare vSphere Distributed Switching for NSX
I’m not 100% sure what they are looking for here. But a good guess (and requirement) is to make sure your DVS has the proper MTU set. The recommendated value from VMware is a minimum of 1600.
Step 1: Go into the DVS we are going to use for our NSX cluster(s) and go to properties and set the MTU to at least 1600. Also, make sure you set the physical underlay switching to the same if not more.
Prepare a Cluster for NSX
First, we need prepare the hosts by installing the software VIB on each host that will be using NSX features. We can achieve this by doing the following.
Navigate to Networking & Security in the vSphere Web Client, click on Installation then Host Preparation.
Under Actions, click Install and select Yes.
The installation will take a few minutes to install. If it appears to be installing after several minutes you may need to refresh the page.
Once complete we should see all green check boxes
Next we need to install the VXLAN component. When we add VXLAN support we will be creating/adding a VMkernel adapter (VTEPS) on each host for communication on each host. We’ll need to create an IP pool or use DHCP since these VMkernels will require an IP address. I’m going to use an IP Pool I’ve already created.
Configure the appropriate teaming policy for a given implementation
Here we are looking for the teaming policy within our DVS. We will want to make sure we have the correct teaming policy for our given requirements and/or goals we’re trying to achieve in terms of availability. Specifically for our VTEP support. We our requirements state we need to run multiple VTEP’s on a single host we may need to have multiple NIC’s and a specific load balancing policy set to meet our availability and/or performance requirements.
