Skills and Abilities

Objective 1.2 – Prepare Host Clusters for Network Virtualization

  • Prepare vSphere Distributed Switching for NSX
  • Prepare a cluster for NSX
    • Add/Remove Hosts from cluster
  • Configure the appropriate teaming policy for a given implementation
  • Configure VXLAN Transport parameters according to a deployment plan

Objective Prerequisites

The following prerequisites are assumed for this Objective:

  • A working VMware vSphere 6.x environment.
  • The VMware NSX Manager has been deployed.
  • At least one VMware NSX Controller has been deployed (if required).

Objective Breakdown

Prepare vSphere Distributed Switching for NSX

I’m unsure what they will expect for us to configure.  However, I would suggest that they will expect the creation of a Distributed Switch with the right port groups and the right MTU value (1600).  I won’t be covering the creation of vDS here, if you are unsure how to do this, then check out the VMware article.

The MTU value, if not set correctly (i.e. 1600 or higher) on creation can be configured by editing the Distributed Switch.

Prepare a cluster for NSX

Note: These steps assume you are not even logged into vCenter Server.  Skip the first few steps if you are!

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Click Network and Security.

Click Installation tab.

Select Host Preparation.

Highlight the target vSphere Cluster and click Actions then Install.

Click Yes.

The installation of the NSX VIBs will now complete.

Add/Remove Hosts to/from a cluster

See HOWTO: Remove a Host from a VMware NSX enabled vSphere Cluster

See HOWTO: Add a Host to a VMware NSX enabled vSphere Cluster

Configure the appropriate teaming policy for a given implementation

Within this knowledge item, I believe it is all about configuring the VMware Distributed Switch with the appropriate load balance method required for the actual implementation and whether you need single or multiple VTEP support.

Configure VXLAN Transport parameters according to a deployment plan

Note: These steps assume you are not even logged into vCenter Server.  Skip the first few steps if you are!

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Click Network and Security.

Click Installation.

Click the Host Preparation tab.

Under VXLAN, click Not Configured.

Select the appropriate Switch from the dropdown, enter the VLAN Id and select Use IP Pool from the VMKNic IP Addressing option.

Click New IP Pool… from the dropdown.

Enter values for the Name of the New IP Pool, the IP Gateway Address, the Prefix Length and the Static IP Pool address range.

Click OK.

Select the appropriate VMKNic Team Policy from the drop down.

Click OK.
