NSX-T Part2 : Host Preparation and adding to NSX-T Fabric

In continuation to the the NSX-T Part1 , in this part we would be preparing the ESXi nodes as a fabric node, i.e essentially installing the NSX-T modules on the nodes and registering them with the NSX-T management plane.

So, the first thing we do is connect to the NSX-T manager using SSH and get the status of the install-upgrade service. This service should be running for the vibs to be automatically installed on the ESXi nodes when we add them in the fabric.


Then , we need to SSH into the ESXi nodes and get the thumbprint from the nodes. You can also skip this step and do not enter any host thumbprint, this is were NSX-T UI will prompt you to accept the retrieved thumbprint. However, for demonstration I have retrieved the thumbprint from the ESXi node SSH.

ESXCLI command to retrieve thumbprint is : openssl x509 -in /etc/vmware/ssl/rui.crt -fingerprint -sha256 -noout


Next, on the browser log in to the NSX-T manager UI , and select Fabric > Nodes > Hosts and click Add. Enter the information as below.



Continue the same process for all the ESXi nodes part of the fabric.

Once the nodes are successfully added to the fabric , their manager connectivity status will show as “UP”.


Also, I have checked the list of vibs which get installed on the ESXi for NSX-T, and their are a bunch of them.


In the next part, I will write about how to prepare the added nodes into fabric as transport nodes and overlay network preparation.
