Create Distributed Switch VDS for NSX Data Center for vSphere

To deploy a VMware NSX Data Center for vSphere your VMware environment should have a vSphere Distributed Switches as a prerequisite. It is recommended to install and configure the VDS in the environment before installing NSX Data Center for vSphere environments. My previous post was about NSX Data Center For vSphere Overview and In this post, we will share the procedure to create VMware vSphere Distributed Switch (VDS) for NSX Data Center and how to configure it with hosts .

Why vSphere Distributed Switch not vSphere Standard Switch with NSX?

First vSphere Distributed Switches is a requirement for NSX Data Center for vSphere. As we aware that multiple hosts network can be managed a centrally using only VDS . Also NSX services are not supported on a vSphere Standard Switch and all hosts within the cluster must be attached to a common VDS to prepare the hosts for NSX Data Center for vSphere. To understand more details on VDS refer vSphere Standard switch vs Distributed switch .

Create a vSphere Distributed Switch (VDS)

Navigate to the Network from vSphere client and right-click the Datacenter name and choose Distributed Switch > New Distributed Switch.

 

Provide a name for the new Distributed Switch and click Next

Select the Distributed switch version , clicking the information bubble will provide you the features per version and you can upgrade any time from the lower version higher version based on compatibility and requirements .

Choose the Number of uplinks per Distributed Switch and select  Network I/O Control if required  Default port group, and Port group name and Click Next

Review the settings and Click Finish to complete .

We have successfully created a new vSphere Distributed Switch (VDS) next will configure ESXi hosts to VDS
Configure ESXi  Hosts to  vSphere Distributed Switch (VDS)
Click on the Distributed Switch  > Add and Manage Hosts

Select the Add hosts option and click Next

Note:- Same Steps can be used to remove the hosts and manage host networking
Click on  +New Hosts option

Next Page will show you  hosts that are compatible with adding to the new VDS  , select  the required hosts to be configured with VDS  and Click Next

You can view Hosts are now selected (New) , Click next

 

From this page you have to choose the physical adapters of ESXi host to use for the vSphere Distributed Switch also if the port is already assigned to Standard Switches, you can migrating them to VDS . Click  on the Assign uplink to assign a chosen physical adapter to the VDS

Here We use one nic (vmnic0) for Standard Switch and another one (vmnic1) for VDS

Select the Uplink  for the nic you have chosen an click OK , you have option use the same uplink assignment for all the hosts you need to configured with VDS

All hosts uplink is are now assigned to DVS  and Click on Next

Next, Configuring the vMkernel adapters for the distributed switch , also you have the option to migrate exiting vmks to VDS  ,and it only required  if you need else leave it as it is and Clik Next .

If you do migration of f vMkernal you have to choose network and port group to migrate the VMkernel adapter to also there is option available to  Apply this port group assignment to the rest of the hosts , refer below image . Note:- Here we are not migrating standard switch vmk to vds

Next is migrate the VM Networking , you can  choose to migrate the VM networking also if required

 

Review the settings and click Finish

 

Conclusion

We have share the procedure to create vSphere Distributed Switch VDS for NSX Data Center through vSphere  HTML 5 client . As I mentioned above Distributed Switch is a requirement for all of the advanced functionality that NSX Data  Center for vSphere .
