NSX-T installation comes with a out of the box self-signed SSL certificate. Because of security and compliance reasons, most of customers want to replace default self-signed certificate with a CA signed certificates. We have been looking for guide that explains how to do this step-by-step but unfortunately we couldn’t find one! There are some very useful guides like this one from VMware but as you read through, you realize the documentation is not complete. So to make story short, we looked around and ran SSL certification replacement.Continue reading “NSX-T 3.0 SSL Certificate Replacement – Part 1”

Configure NSX-T 3.0 RBAC with Native Active Directory Integration
One of the new features which has been added to NSX-T 3.0 is supporting RBAC with Native Active Directory. In previous version of NSX-T we had to use VMware Identity Manager (vIDM) to be able to add users and groups from Active Directory for RBAC purposes. In set posts I have already described how to install and configure vIDM with NSX-T. I still believe configuring RBAC through vIDM has some added value like Multi-Factor Authentication(MFA).
To setup NSX-T Role-based Access Control(RBAC) it’s better to create groups in Active Directory and add users into the group for two reasons. First it’s easier to add a group with couple of users as members rather than assign role to many users in NSX-T. Second, with help of Group Policy you can define a “Restricted Group” and it locks down membership to that group. As a result it provides a layer of security.Continue reading “Configure NSX-T 3.0 RBAC with Native Active Directory Integration”
Configure Virtual IP for NSX-T Management Cluster
Now that we have finalize deploying three managers in NSX-T management cluster we can go ahead and configure a Virtual IP(VIP) on it. We can use NSX-T internal mechanism to set an IP address on the cluster or setup an external load balancer in front of NSX-T managers. Configuring VIP which is recommended by VMware is more simple but using a LB would load balance traffic among NSX-T managers. This is a design question and should be chosen based on requirements and customer needs.
Please keep in mind that if you want to choose this approach, you need to have all NSX-T managers are on the same subnet. In this case, managers are attached to SDDC Management network. To configure Virtual IP, login to NSX-T Manager UI, choose System and on the left panel select Appliances then click on SET VIRTUAL IP option.Continue reading “Configure Virtual IP for NSX-T Management Cluster”
Finalizing NSX-T Management Cluster Deployment
In the previous articles, we deployed first NSX-T Manager and then we added vCenter Server as Compute Manager in NSX-T Web UI. In this post we are going to finalize NSX-T Management cluster. In production environment for high availability and performance reasons, it is recommended to have three NSX-T Managers in the cluster. Second and third NSX-T Managers should be added from NSX-T Web UI. To deploy additional NSX-T manager appliances, go to System menu and choose Appliances and click on “ADD NSX APPLIANCE”.Continue reading “Finalizing NSX-T Management Cluster Deployment”
Add Compute Manager to NSX-T 3.0
In previous blog post we started NSX-T implementation by deploying first NSX-T Manager. Before deploying other two NSX-T Managers we need to add a Compute Manager. As it defines by VMware, “A Compute Manager is an application that manage resources such as hosts and VMs. One example is vCenter Server”. We do this because other NSX-T Managers will be deployed through Web UI and with help of vCenter Server. We can add up to 16 vCenter Servers in a NSX-T Management cluster.
To add compute manager in NSX-T, It is recommended to create a service account and customized vSphere Role instead of using NSX-T default admin account. The reason behind defining a specific role is because of security reasons. As you can see in the below screen shot I created a vSphere Role call “NSX-T Compute Manager” with the required privileges. I use this Role to assign permission to the service account on vCenter Server.Continue reading “Add Compute Manager to NSX-T 3.0”
