It has uplinks used to connect the virtual switch to the physical world. It also supports connections to help you manage your virtual infrastructure.

Only instead of using a wired Ethernet cable, the virtual machine's connection to the port on the virtual switch is often referred to as a 'virtual wire'. The virtual switch can also have one or more uplinks. Uplinks are used to connect the virtual switch within the ESXi host, to an external physical switch. Just as you can connect uplink ports between two physical switches. In the "virtual world" you can connect or 'uplink" a virtual switch to an externa...
