You will need the following data handy before you can create a VMkernel interface:

• Name of the port group (Network label)—most organizations follow a naming standard. It is essential to arrive at an accepted naming format.
• Physical uplinks—not all uplinks are configured to pass all traffic. It important to make sure you identify the correct uplinks. For example, it is possible that only a fixed number of VLANs are trunked to a port the uplink is cabled to.
• An optional VLAN ID.
