A network label specification is used to configure desktop pools that need to automatically place desktops on one of multiple available virtual machine networks, often for network capacity reasons. This feature is currently available only when using PowerCLI.
In this example, the vSphere cluster where your desktop desktops will be deployed has two virtual machine networks named VLAN10 and VLAN20, and each virtual machine network can support no more than 250 desktops. We are going to create a desktop pool that has 500 desktops. To do this using the desktop Manager Admin console, we will need two virtual desktop master images, one connected to each virtual machine network. You will then need to create two desktop pools, one for each virtual desktop master image.
