Deploy services on a Logical Switch in NSX
Note: These services that you deploy to a logical switch are usually third party. For the VCIX-NV test, I don’t believe you will need to know much about this except for attaching the service to a switch.
Step 1. Log into the vSphere Web Client and navigate to Networking & Security -> Logical Switches
Step 2. Select the Service that you would like to add to the logical switch, then click OK.
