Prepare Host Clusters for Network Virtualization

Step 1. Under the Installation section of Networking and Security, navigate to the Host Preparation tab. Click the Install link on your cluster
This will use EAM to install the vibs for NSX on your hosts. If it errors and says its not ready, EAM might not be working properly, which relies on VWS in 5.5. You might also have DNS related issues on your ESXi hosts.

Step 2. Once installed, we’ll configure VXLAN. Click Configure under the VXLAN column.
vxlan configure
Step 3.Choose the DVS, VLAN, Teaming policy and Addressing scheme for VXLAN. I chose to create a new pool of IPs for it to use.

    Hi Sean, I am getting below error during host preparation. I have a LAB environment and can share snapshots via email.

    “Operation is not allowed by the applied NSX license. Please check assigned NSX license and vCenter connectivity.”

    As per VMWare website, NSX Manager is not available for public evaluation. I managed to download the image, linked with vCenter, however, when I tried to install it asks for license. Any workaround for it ? What is the cost to purchase license for lab purposes ?
