Like a physical switch, a virtual switch lets you connect other networking components together. Virtual switches are created as needed by the VMware Workstation software, up to a total of nine switches. You can connect one or more virtual machines to a switch.
By default, a few of the switches and the networks associated with them are used for special named configurations:
The other available networks are simply named VMnet2, VMnet3, VMnet4, and so on.
To connect a virtual machine to a switch: In the virtual machine settings editor, select the virtual network adapter to connect, and then configure the adapter to use the desired virtual network.
